Step 4e , MixCat   If the payload container is proposed for shipment with containers of different shipping categories and/ or dunnage containers, the compliance evaluation shall proceed as presented in Figure 4.6 5 and Section <IP_ADDRESS>.5, Compliance with Flammable ( Gas/ VOC) Limits by Mixing of Shipping Categories in a Payload Assembly.

Step 4f , Flammable ( Gas/ VOC) Concentration   Limits   Is the sum of flammable ( gas/ VOC) concentrations less than or equal to the MLEL? The flammable gas concentration within the innermost layer of confinement of the container must be determined using the data from the testing, as described in Section <IP_ADDRESS> and Appendix 3.10 of the CH TRU Payload Appendices. A specific MLEL must be calculated for the container, as described in HNF 2600, REV 15 Page 119 of 281 5/ 11/ 2005 HANFORD SITE TRANSURANIC WASTE CERTIFICATION PLAN Section <IP_ADDRESS>. If the sum of the flammable gas and VOC concentrations exceeds the MLEL, the container does not comply with flammable ( gas/ VOC) limits. Mitigation measures must then be taken under Step 4g , Mitigate and Update Payload Container Data Package. If the flammable ( gas/ VOC) concentration is less than or equal to the MLEL, the flammable ( gas/ VOC) limits are met, and the compliance evaluation is complete ( see Step 4i , Payload Container Meets Flammable ( Gas/ VOC) Limits).

Step 4g , Mitigate and Update Payload Container Data Package   If the flammable ( gas/ VOC) concentration determined from the testing exceeds the MLEL, the container is not eligible for shipment and must be segregated for repackaging, treatment, or other mitigation measures. Following the completion of mitigation measures, the compliance evaluation shall proceed to Step 4h , " Start."

Step 4h , " Start"   Following the completion and documentation of mitigation measures, the compliance evaluation shall start again as described in Figure 4.6 1 and Section <IP_ADDRESS>.1, Analytical Category: Compliance with Flammable ( Gas/ VOC) Limits.

Step 4i , Payload Container Meets Flammable ( Gas/ VOC) Limits   All containers reaching this step meet the flammable ( gas/ VOC) limits and are eligible for shipment if all other transportation requirements are satisfied.

<IP_ADDRESS>.5 Compliance with Flammable ( Gas/ VOC) Limits by Mixing of Shipping Categories in a Payload Assembly If the payload container under evaluation is proposed for shipment with containers of different shipping categories and/ or dunnage containers ( as determined in Step 1f of Figure 4.6 1, Step 3d of Figure 4.6 3, or Step 4d of Figure 4.6 4), the compliance with flammable ( gas/ VOC) limits must be evaluated for each container in the payload assembly. This method accounts for the use of dunnage containers to assemble the payload.

Figure 4.6 5 presents the logic for performing the compliance evaluation for flammable ( gas/ VOC) limits for the use of mixing of shipping categories in a payload assembly, which consists of the following steps:

Step 5a , Data Packages for Containers in Proposed Payload Assembly   The starting point for compliance evaluation for mixing of shipping categories in a payload assembly is the data packages for all payload containers proposed for inclusion in the payload.

Step 5b , Flammability Index for Each Container in Assembly   50,000   Is the flammability index ( FI) for each container proposed for inclusion in the payload assembly a non negative number   50,000? For each payload container, an FI must be calculated as the ratio of the actual flammable gas generation rate to the allowable flammable gas generation rate limit multiplied by 50,000. Appendix 2.4 of the CH TRU Payload Appendices describes the methodology for determining the FI for payload assemblies with mixed shipping categories. If the FI for any payload container is a negative number or exceeds 50,000, the compliance evaluation shall HNF 2600, REV 15 Page 120 of 281 5/ 11/ 2005 HANFORD SITE TRANSURANIC WASTE CERTIFICATION PLAN proceed to Step 5c , Reconfigure Payload Assembly. If the FI for each payload container in the payload assembly is a non negative number less than or equal to 50,000, the flammable ( gas/ VOC) limits are met and the compliance evaluation is complete ( see Step 5h , Payload Container Meets Flammable ( Gas/ VOC) Limits).

Step 5c , Reconfigure Payload Assembly   Can the payload assembly be reconfigured by proposing a different combination of payload containers? If the proposed payload assembly cannot be reconfigured, compliance with the flammable ( gas/ VOC) limits cannot be met for the proposed payload assembly. Mitigation measures must be taken under Step 5d , Mitigate and Update Payload Container Data Package. If the proposed payload assembly can be reconfigured with a different assembly of containers, the compliance evaluation shall proceed to Step 5f , Compile Data Packages for Revised Payload Assembly.

Step 5d , Mitigate and Update Payload Container Data Package   If the payload assembly cannot be reconfigured, the payload is not eligible for shipment and the payload containers exceeding the FI in the proposed payload assembly must be segregated for repackaging, treatment, or other mitigation measures. Following the completion of mitigation measures, the compliance evaluation shall proceed to Step 5e , " Start."

Step 5e , " Start"   Following the completion and documentation of mitigation measures, the compliance evaluation shall start again as described in Figure 4.6 1 and Section <IP_ADDRESS>.1, Analytical Category: Compliance with Flammable ( Gas/ VOC) Limits.

Step 5f , Compile Data Packages for Revised Payload Assembly   Following the compilation of the data packages for payload containers comprising the reconfigured payload assembly, the compliance evaluation shall proceed to Step 5g , To Step 5a Above.

Step 5g , To Step 5a Above   The evaluation of the reconfigured payload assembly shall start again under Step 5a , Data Packages for Containers in Proposed Payload Assembly.

Step 5h , Payload Container Meets Flammable ( Gas/ VOC) Limits   All payload assemblies reaching this step meet the flammable ( gas/ VOC) limits and are eligible for shipment if all other transportation requirements are satisfied.

<IP_ADDRESS> Hydrogen Gas Generation Rate and Decay Heat Limits for Analytical Category The maximum allowable hydrogen gas generation rate limit and decay heat limit, which will limit the concentration of hydrogen gas within any layer of confinement to less than or equal to 5% by volume, may be determined for alpha numeric and numeric shipping categories. Appendix 2.3 of the CH TRU Payload Appendices presents the methodology used for deriving the limits for alpha numeric shipping categories and the derivations of the formulas used to calculate the limits for numeric shipping categories. Appendix 6.9 of the CH TRU Payload Appendices describes the temperature dependence of hydrogen gas generation and release rates. Appendix 6.10 of the CH TRU Payload Appendices documents the effect on decay heat limits of overpacking containers. HNF 2600, REV 15 Page 121 of 281 5/ 11/ 2005 HANFORD SITE TRANSURANIC WASTE CERTIFICATION PLAN Table 4.6.2 1 lists the limits for approved alpha numeric shipping categories.

For numeric shipping categories that do not have a corresponding alpha numeric shipping category listed in Table 4.6.2 1, the procedure for determining limits is presented here. The method for calculating the decay heat limit and gas generation limit for numeric shipping categories is simple and conservative to provide a direct correlation between shipping category and the limits.

The numeric shipping category notation ( as described in Appendix 2.1 of the CH TRU Payload Appendices) is in the form of XX YYYY ZZZZ, where XX represents the waste type, YYYY represents the G value ( multiplied by 100), and ZZZZ represents the total resistance, RT, ( divided by 10,000 and rounded up). The hydrogen gas generation rate limit per innermost layer of confinement, CG, and the decay heat limit per innermost layer of confinement, Qi, are determined by the following equations:

CG = 0.05 ( ZZZZ * 10,000) sec/ mole and Qi = ( 4824.42) molecules/ mole * watt sec/ eV ( ZZZZ * YYYY) sec molecules/ mole eV For example, for shipping category 10 0040 0160, substituting 0040 for YYYY and 0160 for ZZZZ yields:

CG = 0.05 = 3.125E 08 mole/ sec ( 0160 * 10,000) sec/ mole Qi = 4824.42 molecules/ mole * watt sec/ eV = 0.7538 watts ( 0160 * 0040) sec molecules/ mole eV HNF 2600, REV 15 Page 122 of 281 5/ 11/ 2005 HANFORD SITE TRANSURANIC WASTE CERTIFICATION PLAN Table 4.6.2 1  List of Approved Alpha numeric Shipping Categories, Maximum Allowable Hydrogen Gas Generation Rates, and Maximum Allowable Wattages Numeric Payload Shipping Category Alpha numeric Payload Shipping Category Maximum Allowable Hydrogen Gas Generation Rate ( moles/ sec) Maximum Allowable Wattage ( watts) 10 0040 0034 I. 3C0 1.514E 07 3.6528 10 0040 0147 I. 3A0 3.416E 08 0.8241 10 0040 0168 I. 3A1 2.980E 08 0.7189 10 0040 0190 I. 3A2 2.643E 08 0.6375 10 0040 0207 I. 3B0 2.416E 08 0.5827 10 0040 0229 I. 3B1 2.189E 08 0.5281 10 0040 0250 I. 3B2 2.002E 08 0.4828 10 0040 0648 I. 3A3 7.721E 09 0.1863 10 0040 0709 I. 3B3 7.061E 09 0.1703 10 0040 0888 I. 3A4 5.634E 09 0.1359 10 0040 0949 I. 3B4 5.274E 09 0.1272 10 0130 0034 I. 2C0 1.514E 07 1.1240 10 0130 0147 I. 2A0 3.416E 08 0.2536 10 0130 0168 I. 2A1 2.980E 08 0.2212 10 0130 0190 I. 2A2 2.643E 08 0.1962 10 0130 0207 I. 2B0 2.416E 08 0.1793 10 0130 0229 I. 2B1 2.189E 08 0.1625 10 0130 0250 I. 2B2 2.002E 08 0.1486 10 0130 0648 I. 2A3 7.721E 09 0.0573 10 0130 0709 I. 2B3 7.061E 09 0.0524 10 0130 0888 I. 2A4 5.634E 09 0.0418 10 0130 0949 I. 2B4 5.274E 09 0.0391 10 0160 0034 I. 1C0 1.514E 07 0.9132 10 0160 0059 I. 1C2 8.598E 08 0.5185 10 0160 0147 I. 1A0 3.416E 08 0.2060 10 0160 0168 I. 1A1 2.980E 08 0.1797 10 0160 0190 I. 1A2 2.643E 08 0.1594 10 0160 0207 I. 1B0 2.416E 08 0.1457 HNF 2600, REV 15 Page 123 of 281 5/ 11/ 2005 HANFORD SITE TRANSURANIC WASTE CERTIFICATION PLAN Table 4.6.2 1  List of Approved Alpha numeric Shipping Categories, Maximum Allowable Hydrogen Gas Generation Rates, and Maximum Allowable Wattages ( Continued)

Prior to performing headspace sampling, DACs need to be met for headspace samples to be valid and is performed in accordance with WMP 400, Section 7.1.8. DACs are estimates of time required for VOCs in a payload container to reach 90 percent of the equilibrium steady state concentration within the different layers of confinement. Alternately, the headspace sample taken before the DAC has been met can be used to determine the 90% steady state concentration in a waste container. The 90% steady state concentration can then be correlated to the VOC concentration in the innermost HNF 2600, REV 15 Page 126 of 281 5/ 11/ 2005 HANFORD SITE TRANSURANIC WASTE CERTIFICATION PLAN layer of confinement by the use of prediction factors ( PFs), which are multipliers to be applied to the headspace concentration. The method used for determining the steady state ( 90%) VOC concentration from DACs ( or measurement) and PFs is based on Liekhus et al., October 2000.2 Three options are available:

Option 1 No DACs Required. If the concentration of flammable VOCs in a payload container can be shown to be less than or equal to 500 ppm from the waste generation procedures or records of process knowledge, then no DACs or PFs are required. If the concentration of flammable VOCs cannot be determined from the waste generation procedures or the records of process knowledge, headspace sampling must be performed and Option 2 or Option 3 below must be used.

Option 2 Assignment of DACs for Common Packaging Configurations. DACs for common representative packaging configurations used for CH TRU waste at the sites are presented in look up tables. Under Option 2, there are three container venting and sampling scenarios. Option 2 and the associated scenarios and look up tables are discussed in detail in Section Section <IP_ADDRESS> under Assignment of DACs for Common Packaging Configurations. DACs are determined and documented using WMP 400, Section 7.1.8.

Option 3 Calculation of Steady State VOC Concentrations for Specific Packaging Configurations. For specific packaging configurations not covered by Option 2, the steady state VOC concentration can be determined based on sampling ( measurement) using the methodology described in Liekhus et al., October 2000.2 Option 3 is described in Appendix 3.9 of the CH TRU Payload Appendices.

Figure 4.6.2 3 presents a flowchart for determining the appropriate option. A list of flammable VOCs identified by the sites in CH TRU waste is provided as Table 4.6.2 2. If additional flammable VOCs ( i. e., not listed in Table 4.6.2 2) are identified in concentrations greater than 500 ppm total, Section <IP_ADDRESS>, under Determine Concentration of Flammable VOCs Using PFs, specifies a formalized process for including these VOCs in the analysis for compliance with the flammable ( gas/ VOC) limits.

Assignment of DACs for Common Packaging Configurations The derivation of the DACs for Option 2 is based on specific packaging configurations and waste types commonly used at the TRU waste sites. Considering only the number of layers of confinement, the common packaging configurations currently described in the CH TRUCON document1 can be bound by the packaging configurations presented in Table 4.6.2 3.

For example, a packaging configuration consisting of a single plastic bag in a 55 gallon drum for Waste Type II or III could be conservatively placed into Configuration 2 ( i. e., the DAC for a packaging configuration consisting of 1 inner bag would be less than or equal to that for 3 inner bags and 1 liner bag). Similarly, a configuration of 2 inner bags and 2 liner bags in a 55 gallon drum for these waste types would be assigned to Configuration 3. In addition, filtered bag layers are also conservatively assigned to the configurations in Table 4.6.2 3. For example, a configuration of Waste Type II with 3 filtered inner bags and 1 filtered liner bag in a 55 gallon drum is bounded by Packaging Configuration 2. HNF 2600, REV 15 Page 129 of 281 5/ 11/ 2005 HANFORD SITE TRANSURANIC WASTE CERTIFICATION PLAN Table 4.6.2 3   Common CH TRU Waste Packaging Configurations Packaging Configuration Waste Types II and III Waste Types I and IV Packaging Configuration 1 ( 55 gallon drums) No inner bags, no liner bags Packaging Configuration 2 ( 55 gallon drums) Up to 4 bag layers, up to 1 of which is a liner bag Any configuration with 1 liner bag Packaging Configuration 3 ( 55 gallon drums) Up to 6 bag layers, up to 2 of which are liner bags Any configuration with 2 liner bags Packaging Configuration 4 ( pipe components) Up to 2 inner bags and 1 filtered metal can inside a pipe component ( headspace sample taken inside the pipe component) Packaging Configuration 5 ( SWBs and TDOPs) SWB or TDOP with up to 1 bag layer ( inner or liner)

Packaging Configuration 6 ( SWBs and TDOPs) SWB or TDOP with up to 6 bag layers, up to 1 of which is a liner bag Packaging Configuration 7 ( 85 gallon drums) 85 gallon drum with filtered inner lid ( no inner or liner bags and no rigid liners)

For Waste Types I and IV in 55 gallon drums, one or two liner bags are the configurations most commonly used. The DAC analysis conservatively assumes for solidified wastes that only the top of the liner bag is available for VOC transport. The presence of inner bags makes the entire liner bag area available and hence the DACs are bound by the configurations in Table 4.6.2 3.2 Any site requiring the transportation of TRU waste in the TRUPACT II or HalfPACT that cannot be covered under a packaging configuration included in Table 4.6.2 3 must request the determination of an appropriate DAC by submitting a request in writing to the WIPP CH TRU Payload Engineer.

The WIPP CH TRU Payload Engineer shall assign a conservative DAC for a packaging configuration not covered under Table 4.6.2 3 using the governing equations and methodology. 2,3 Compliance with all other transportation requirements of the CH TRAMPAC document shall also be demonstrated. The WIPP CH TRU Payload Engineer does not have the authority to change the transportation requirements for the TRUPACT II as specified in the CH TRAMPAC document without approval from the NRC. Section 4.1 describes the process for WIPP CH TRU Payload Engineer approval of new packaging configurations as part of the TRUCON code approval process.

DACs are defined for three unique venting and sampling scenarios. These venting and sampling scenarios are defined by the time elapsed after container closure and venting, as follows:

t1 = time ( days) elapsed after container closure until venting t2 = time ( days) elapsed after venting. HNF 2600, REV 15 Page 130 of 281 5/ 11/ 2005 HANFORD SITE TRANSURANIC WASTE CERTIFICATION PLAN Scenario 1: The drum liner headspace ( under liner lid) can be sampled at the time of venting if t1 is greater than DAC1. The drum age criterion DAC1 is defined as the time for a representative VOC to reach a concentration of at least 90% of its equilibrium concentration before drum venting. Table 4.6.2 4 presents the DAC1 values.

Table 4.6.2 4   DAC1 Values ( in Days)

Waste Type DAC1 ( days) Waste Types I and IV 127 Waste Types II and III 53 Scenario 2: For drums generated in an unvented condition and subsequently vented, the drum headspace can be sampled in a vented drum if t1 is greater than DAC1 and t2 is greater than DAC2.

The drum age criterion DAC2 is defined as the time for a representative VOC to reach a headspace concentration of at least 90% of its steady state concentration after venting a waste drum that was unvented for at least DAC1. DAC2 values are calculated for the two categories of waste types under Scenario 1 with four different opening sizes in the punctured drum liner lid and three different drum filter diffusivities.

In other words, under this scenario, if the drum has remained in an unvented condition for a period of at least 53 days for Waste Types II and III and 127 days for Waste Types I and IV, equilibration of VOCs is complete inside the drum. When the drum is subsequently vented, a time period for the appropriate DAC2 listed in Table 4.6.2 5 or 4.6.2 6 is needed before sampling to ensure reequilibration between the liner and the drum headspace.

Scenario 3: If t1 is less than DAC1 when the container is vented, the container headspace can be sampled when t2 is greater than DAC3. Also, for newly generated payload containers that were vented at the time of generation, the container headspace can be sampled after DAC3 has been exceeded.

The drum age criterion DAC3 is defined as the time for a representative VOC to reach a headspace concentration of at least 90% of its steady state concentration. DAC3 values are calculated for the two categories of waste types each with different packaging configurations, different opening sizes in the drum liner lid as well as the case of no rigid liner inside the drum, and different filter diffusivities. The appropriate DAC3 values are listed in Tables 4.6.2 7 and 4.6.2 8.

Because direct load TDOPs are equipped with a greater number of filters than SWBs, the SWB packaging configurations ( Packaging Configurations 5 and 6) bound the direct load TDOP packaging configurations.

Packaging Configuration 7 describes 85 gallon drums with a vented inner lid and no additional inner layers of confinement and no rigid liners. Sampling is performed between the inner and outer lids or inside the inner lid. The DAC values for an 85 gallon drum with no additional inner layers of confinement and no rigid liner are listed in Tables 5.2 7 and 5.2 8.

HNF 2600, REV 15 Page 136 of 281 5/ 11/ 2005 HANFORD SITE TRANSURANIC WASTE CERTIFICATION PLAN <IP_ADDRESS> United Flammable Gas Test Procedure Introduction CH TRU wastes to be transported in the TRUPACT II packages fall into one of two categories based on their gas generation potential   " analytical category waste" or " test category waste." The wastes that can be qualified for shipment based on decay heat limits derived from theoretical worst case calculations of gas generation potential comprise the " analytical category." The CHTRU waste containers that exceed the applicable decay heat limits set for the analytical category, or that exceed 500 ppm of flammable VOCs in the headspace, or that do not have an established theoretical bounding gas generation rate ( G value), belong in the " test category." The Unified Flammable Gas Test Procedure ( UFGTP) details the methodology used to evaluate compliance of test category wastes with flammable ( gas/ VOC) limits.

Purpose This UFGTP provides the technical basis for determining whether a test category payload container demonstrates compliance with the flammable ( gas/ VOC) limits. It also provides instructions for the methodology by which each test activity will be performed. The first, or short term, objective of the UFGTP is to facilitate shipment of waste in the test category by testing individual payload containers to show compliance with the flammable gas generation and concentration requirements. The second, or long term, objective is to improve waste shipability for specific populations or subpopulations of waste by arriving at more realistic gas generation rates based on the results of measurement and testing ( Hanford is not implementing this testing method at this time). The process for implementation of the long term objective is defined in the " UFGTP Long Term Objective Implementation Method" 3 and described in Section <IP_ADDRESS> under Determine Compliance with Flammable Gas Generation Rate Limit.

Applicability This procedure applies to individual containers of CH TRU waste that fall into the test category. Containers are placed into the test category if they fall into one of the following classifications.

  The decay heat loading of the waste container exceeds the analytical category decay heat limit for the shipping category of that payload container and the total concentration of potentially flammable VOCs within the container headspace is less than or equal to 500 ppm. Payload containers in Waste Types I ( 10), II ( 20), and III ( 30) belong in this category.   The total concentration of potentially flammable VOCs within the container headspace exceeds 500 ppm. Payload containers in Waste Type I ( 10), II ( 20), and III ( 30) belong in this category.

HNF 2600, REV 15 Page 137 of 281 5/ 11/ 2005 HANFORD SITE TRANSURANIC WASTE CERTIFICATION PLAN   A waste process does not have a fully characterized bounding G value from previous sampling or waste stream analysis. Payload containers in Waste Type IV ( 40) belong to this category. Hanford is not shipping waste type IV ( 40) at this time.

Summary of Procedure The UFGTP details the method used to evaluate the compliance of test category wastes with flammable ( gas/ VOC) rate and concentration limits. As described in Section <IP_ADDRESS> of this document, the evaluation of compliance of test category wastes with the limits is carried out through the use of one of two methods:

  Measurement   Testing.

The procedure outlined in this document is valid to show compliance on a per container basis assuming that each container will be assembled into a payload with payload containers belonging to the same payload shipping category, as defined in Section 4.6.1 of this document. Compliance evaluation requirements for payloads with multiple shipping categories and/ or dunnage containers are described in Sections <IP_ADDRESS> of this document. Data obtained from this procedure may be used in the mixing methodology for compliance with flammable ( gas/ VOC) limits described in Section 4.7.4 and the evaluation for compliance with payload total gas release rate limits described in Section 4.7.1.

Hanford is only implementing the measurement evaluation method and relies on WWIS for UFGTP calculations. Information is entered into WWIS using WMP 400, Section 7.1.5.

Measurement This consists of using a headspace gas measurement ( taken under the container lid, liner lid, or pipe component lid) along with the waste packaging configuration and history of the container to demonstrate compliance with flammable ( gas/ VOC) limits. This is applicable to test category wastes of Waste Types I, II, and III that exceed decay heat limits and/ or exceed 500 ppm flammable VOCs in the headspace of the payload container. The headspace concentrations of the flammable gases and the time history of the payload containers are used to determine the gas/ VOC concentrations in the innermost confinement layer. The flammable gas generation rates are determined from these measured concentrations using analytical solutions as discussed in Appendix 3.10 of the CH TRU Payload Appendices.

The headspace flammable ( gas/ VOC) concentrations are also used to determine compliance with the MLEL as discussed in Appendix 3.10 of the CH TRU Payload Appendices. The headspace concentrations of methane are evaluated for compliance with the screening limit of 1,250 ppm. Compliance with the allowable flammable ( gas/ VOC) concentrations using headspace gas measurement is described in detail in Section <IP_ADDRESS> under Procedure for Measurement.

For all containers, flammable ( gas/ VOC) concentrations may be measured in an inner layer of confinement rather than the payload container headspace. HNF 2600, REV 15 Page 138 of 281 5/ 11/ 2005 HANFORD SITE TRANSURANIC WASTE CERTIFICATION PLAN If the headspace of the outermost ( overpacking) payload container of an overpacked configuration with multiple containers ( drums in an SWB) is measured, the packaging configuration must be described as a direct load configuration in order to apply the limits specified in this section.

Testing Hanford is not implementing testing at this time.

Procedure for Measurement Compliance with transportation requirements through either measurement or testing shall either be documented on the CH TRU Waste Test Category Payload Container Data Sheet ( the Data Sheet) ( Appendix B 3) or shall be compiled through the use of a verified/ validated software package based on the method presented in this section and in Appendix 3.10 of the CH TRU Payload Appendices. If documented manually, Test Category Payload Container Datasheet in Appendix B 3 may be reformatted for site purposes, but all information on the data sheet shall be retained. If sections of the data sheet are not applicable, mark as such ( e. g., " not applicable" or " NA"). Record the identification parameters identified in Section 1 of the Data Sheet prior to proceeding to the other sections.

If a verified/ validated software package is used, the necessary data shall be input and recorded to assess transportation compliance and the Test Category Payload Container Datasheet in Appendix B 3 need not be completed.

The compliance evaluation for flammable ( gas/ VOC) limits by measurement is as described below:

Determine Compliance with Methane Screening Limit 1. Determine the headspace concentration of methane. The headspace measurement methods and the associated QA requirements are discussed in the Quality Assurance Program Plan ( QAPP) for the TRUPACT II Gas Generation Test Program. 4 2. Record the location of methane measurement ( container headspace or inside the rigid drum liner, if applicable), the date of methane measurement ( if applicable), and the determined concentration of methane ( see Section 2 of the Data Sheet).

4 U. S. Department of Energy ( DOE), " Quality Assurance Program Plan for TRUPACT II Gas Generation Test Program," DOE/ WIPP 01 3187, current revision, U. S. Department of Energy, Carlsbad Field Office, Carlsbad, New Mexico. HNF 2600, REV 15 Page 139 of 281 5/ 11/ 2005 HANFORD SITE TRANSURANIC WASTE CERTIFICATION PLAN 3. Compare the methane concentration to the 1,250 ppm screening limit. Indicate on the Data Sheet by ( Yes/ No) if the methane concentration is less than or equal to 1,250 ppm. ( The rationale for the methane screening limit is provided below.)

Position: A methane screening limit or concentration of 1,250 ppm in the container headspace should be used in flammability evaluations. If the container headspace methane concentration is below this screening limit, the concentration of methane should be added to the hydrogen concentration and the flammable gas generation rate should be determined. If the concentration is above the screening limit, the container is not eligible for shipment and the container shall be either repackaged or mitigation measures shall be adopted.

Rationale: Although the term " flammable gases" includes both hydrogen and methane, gas measurement data suggest methane is either not present or is present in very low concentrations. Laboratory analysis of methane concentration in the container headspace to date has been performed on approximately 14,000 CH TRU waste containers representing a broad spectrum of TRU waste content codes. In only two cases has methane been detected at concentrations greater than 1,000 ppm. Methods currently used by the Rocky Flats Environmental Technology Site and proposed for use for determining methane concentration in the headspace have minimum detection limits that range from 25 to 500 ppm. Other instruments ( e. g., gas chromatograph with flame ionization detector or with thermal conductivity detector) have minimum detection limits ranging from 5 to 100 ppm. All of these instruments will provide data of adequate accuracy and precision to determine if the 1,250 ppm methane screening limit has been met.

The 1,250 ppm methane screening limit concentration is equivalent to:

  2.5% of the methane lower explosive limit of 5 percent by volume   Fraction of the methane contribution to the flammable gas G value for polyethylene ( i. e., [ 0.1 molecules methane/ 100 eV] / [ 4.1 molecules flammable gas / 100 eV] or 2.4%).

If the methane concentration exceeds the 1,250 ppm screening limit, the payload container is not eligible for shipment and cannot be tested under this procedure and must be segregated for repackaging or other mitigation measures. If the methane concentration is less than or equal to 1,250 ppm, and if flammable VOCs could be present at concentrations greater than 500 ppm in the payload container headspace based on process knowledge, proceed to Section <IP_ADDRESS>, Determine Concentration of Flammable VOCs Using PFs. Otherwise, mark the appropriate box in Section 3 of the Data Sheet that shows that flammable VOCs in the headspace are less than or equal to 500 ppm and proceed to Section <IP_ADDRESS>, Determine Compliance with the Packaging Design Pressure Limit by Theoretical Analysis. HNF 2600, REV 15 Page 140 of 281 5/ 11/ 2005 HANFORD SITE TRANSURANIC WASTE CERTIFICATION PLAN Determine Concentration of Flammable VOCs Using PFs 1. Based on the methodology presented in Section <IP_ADDRESS>, determine the payload container headspace concentration ( 90% steady state) from the headspace measurement for each of the flammable VOCs listed in Table 5.2 2. If additional flammable VOCs ( i. e., not listed in Table 4.6.2 2) are identified in concentrations greater than 500 ppm total, the following process shall be used to include these VOCs in the analysis for compliance with flammable ( gas/ VOC) limits.

Each flammable VOC not listed in Table 4.6.2 2 will be identified by name and corresponding Chemical Abstracts Service number. A list of these VOCs shall be submitted by the shipper to the WIPP CH TRU Payload Engineer for evaluation. For each VOC, the WIPP CH TRU Payload Engineer will direct the evaluation of required physical and chemical properties in order to calculate the PF using the methodology documented in Appendix 3.9 of the CH TRU Payload Appendices and the Group Contribution Factor ( GCF) using the methodology documented in Appendix 3.10 of the CH TRU Payload Appendices.

Record the measured concentration in units of ppm for each flammable VOC and for the sum of flammable VOCs ( Section 3 of the Data Sheet). If the sum of flammable VOCs in the payload container headspace is less than or equal to 500 ppm, proceed to Section <IP_ADDRESS>, Determine Compliance with the Packaging Design Pressure Limit by Theoretical Analysis. Otherwise, proceed to Step B.

2. For each flammable VOC, multiply the flammable VOC concentration in the payload container headspace by the appropriate PF to predict the concentration of each flammable VOC within the innermost confinement layer. The PFs are determined for the payload container based on its packaging as described in Section <IP_ADDRESS>. Record the predicted innermost confinement layer concentration for each flammable VOC ( Section 3 of the Data Sheet).

3. Sum the predicted innermost confinement layer flammable VOC concentrations and record the sum ( Section 3 of the Data Sheet).

4. Proceed to Section <IP_ADDRESS>, Determine Compliance with the Packaging Design Pressure Limit by Theoretical Analysis to see if compliance with the TRUPACTII design pressure limit can be established by theoretical analysis.

Determine Compliance with the Packaging Design Pressure Limit by Theoretical Analysis As described in Section 3.4.4 of the TRUPACT II SARs, compliance with the TRUPACT II design pressure limits can be demonstrated by conservative theoretical analysis up to the wattage limits shown in Table 4.6.2 9 for Waste Types I, II, and III. HNF 2600, REV 15 Page 141 of 281 5/ 11/ 2005 HANFORD SITE TRANSURANIC WASTE CERTIFICATION PLAN Table 4.6.2 9   Wattage Limits for Theoretical Analysis of Design Pressure Limit Waste Type Container Type Wattage Limit per Payload Container and per TRUPACT II 55 gallon drum 40 Other container typesa 40 I TDOP 40 55 gallon drum 40 Other container typesa 40 II TDOP 40 55 gallon drum 37 Direct load SWB 23 55 gallon drum in an SWB overpack 38 85 gallon drum, 85 gallon drum overpack, or 55 gallon drum in an 85 gallon drum overpack 26 III TDOP 18 aOther container types are defined as follows: direct load SWB, 55 gallon drum in an SWB overpack, 85 gallon drum, 85 gallon drum overpack, and 55 gallon drum in an 85 gallon drum overpack. NA = Not applicable For cases where the wattage limits specified in Table 4.6.2 9 are exceeded but the packaging design limit of 40 watts per TRUPACT II is met, compliance with the container flammable gas generation rate limit by the method described in Section <IP_ADDRESS>, under Determine Compliance with Flammable Gas Generation Rate or Section <IP_ADDRESS>, under Determine Compliance with Flammable ( Gas/ VOC) Concentration limit, can be used to evaluate compliance with the total gas generation rate limit. Because the primary mechanism for gas generation for both flammable and total gas for Waste Types I, II, and III is radiolysis, compliance with the flammable gas generation rate limit implies actual G values ( both flammable and total) that are much lower than those used to derive the limits in Table 4.6.2 9. Therefore, compliance with the flammable gas generation rate limits will ensure compliance with the total gas generation rate limits for these cases ( e. g., Waste Type III SWBs greater than 23 watts in a TRUPACT II. An example calculation is provided below:

Assuming an SWB of Waste Material Type III. 1 with no layers of confinement and a decay heat loading of 30 watts, compliance with the total gas generation rate limit is ensured if compliance with the flammable gas generation rate limit can be demonstrated by measurement or testing. Using the equations in Section <IP_ADDRESS>, the maximum allowed hydrogen gas generation rate for the test category SWB can be calculated as 1.79E 07 moles/ second. Based on the 30 watt decay heat loading of the SWB and the requirement for the SWB hydrogen gas generation to be less than or equal to 1.79E 07 moles/ second, the actual G value ( flammable gas) for this container can be calculated as 0.06. This compares to a theoretical G value ( flammable gas) of 1.09 used to derive the analytical category limits. Because the mechanism for both hydrogen and total gas generation is HNF 2600, REV 15 Page 142 of 281 5/ 11/ 2005 HANFORD SITE TRANSURANIC WASTE CERTIFICATION PLAN radiolysis, a similar ratio exists between the actual and theoretical gas generation rates for hydrogen and total gas. This means that if the SWB passes the hydrogen gas generation rate limit of 1.79E 07 moles/ second, the actual G value ( total gas) for this container will be lower than the theoretical G value used to derive the limits in Table 4.6.2 9 by a factor of 1.09/ 0.06 = 18. Therefore, the actual total gas generation from this container will be extremely low and will easily comply with the packaging design pressure limits.

Determine the sum of the measured decay heat value and the decay heat measurement error ( one standard deviation) for the payload container from its data package. Record the decay heat plus the associated error and the wattage limit for the container and waste type from Table 4.6.2 9 ( Section 4 of the Data Sheet), and compare the two values. ( Note that the limits specified in Table 4.6.2 9 are per payload container and per TRUPACT II.) If the container decay heat plus error is less than or equal to the appropriate value in Table 5.2 9 and the concentration of flammable VOCs in the payload container headspace is less than or equal to 500 ppm, proceed to Section <IP_ADDRESS>, under Determine Compliance with Flammable Gas Generation Rate. If the container decay heat plus error is less than or equal to the appropriate value in Table 4.6.2 9 and the concentration of flammable VOCs in the payload container headspace is greater than 500 ppm, proceed to Section <IP_ADDRESS>, under Determine Compliance with Flammable Gas ( Gas/ VOC) Concentration Limit. If the container decay heat plus error is greater than the appropriate value in Table 4.6.2 9, then the container may be evaluated for compliance for flammable gas generation rate limits as described in Section <IP_ADDRESS>, under Determine Compliance with Flammable Gas Generation Rate and Section <IP_ADDRESS>, under Determine Compliance with Flammable Gas ( Gas/ VOC) Concentration Limit. If compliance with the flammable gas generation rate limits is demonstrated, then the total gas generation rate limits are met as described above.

Determine Compliance with Flammable Gas Generation Rate Limit 1. Calculate the flammable gas generation rate ( FGGR) within the innermost layer of confinement using the measured flammable gas concentration in the container and the time history of the payload container using the AltMeth algorithm described in Appendix 3.10 of the CH TRU Payload Appendices. Headspace measurement methods and associated QA/ QC requirements are provided in the QAPP. 5 Record the calculated FGGR ( Section 4 of the Data Sheet).

2. Record the maximum allowable hydrogen gas generation rate for the corresponding shipping category determined in accordance with the methodology described in Section <IP_ADDRESS> ( Section 4 of the Data Sheet).

3. Compare the calculated FGGR to the maximum allowable hydrogen gas generation rate. If the calculated FGGR is less than or equal to the maximum allowable hydrogen gas generation rate, then the payload container may be shipped if compliance with all other transportation requirements is demonstrated. If the calculated FGGR exceeds the maximum allowable hydrogen gas generation rate, the container may be reassessed for compliance with transportation HNF 2600, REV 15 Page 143 of 281 5/ 11/ 2005 HANFORD SITE TRANSURANIC WASTE CERTIFICATION PLAN requirements through the evaluation of a payload with different shipping categories or dunnage containers, as described in Section 4.7.4.

If the calculated FGGR for each overpacked container is less than or equal to the maximum allowable hydrogen gas generation rate for the payload shipping category, then the overpack may be shipped if compliance with all other transportation requirements is demonstrated.

If the calculated FGGR of any type of overpacked container exceeds the maximum allowable hydrogen gas generation rate limit of the payload shipping category, the container may be reassessed under the logic of Appendix 2.4 of the CH TRU Payload Appendices.

If the calculated FGGR of an overpacked container exceeds the maximum allowable hydrogen gas generation rate for the payload shipping category and is not reassessed through the logic of Appendix 2.4 of the CH TRU Payload Appendices, then the overpack shall be reconfigured, or mitigative measures shall be adopted. For mixing of container shipping categories within an overpack configuration, the configuration must be assessed under the logic of Section 4.7.4 and Appendix 2.4 of the CH TRU Payload Appendices.

If the above relevant limits are met, the payload container satisfies the test criteria. If the Data Sheet is used to document compliance, then the Data Sheet is signed by the Transportation Certification Official. If compliance is determined using a verified/ validated software package, then the necessary data are stored electronically and the Transportation Certification Official signs the completed PCTCD or OPCTCD, as appropriate. The payload container qualifies for shipment after verification of all of the transportation parameters. Containers that do not meet the test category criteria are segregated for repackaging or reprocessing.

Determine Compliance with Flammable ( Gas/ VOC) Concentration Limit 1. Calculate the FGGR within the innermost layer of confinement using the measured flammable gas concentration in the payload container and the time history of the container ( based on the method in Appendix 3.10 of the CH TRU Payload Appendices). Headspace measurement methods and associated QA/ QC requirements are provided in the QAPP5. Record the calculated FGGR ( Section 4 of the Data Sheet).

2. Calculate the concentration of the flammable gas within the innermost confinement layer at the end of the shipping period inside a TRUPACT II ( Xinner) using the following equation:

T inner R CG X * =

where, HNF 2600, REV 15 Page 144 of 281 5/ 11/ 2005 HANFORD SITE TRANSURANIC WASTE CERTIFICATION PLAN CG = Calculated FGGR ( mole/ second) RT = The total resistance to hydrogen release ( second/ mole) ( see Appendix 2.2 of the CH TRU Payload Appendices).

Record the calculated innermost confinement layer flammable gas concentration ( Section 4 of the Data Sheet).

3. Calculate the container specific MLEL within the innermost confinement layer using the flammable group method as described in Appendix 3.10 of the CH TRU Payload Appendices using the following equation:

i i GCF f % MLEL   = 100 where,

MLEL = Mixture lower explosive limit ( volume percent) fi = Fraction of flammable gas i in mixture on an air free and nonflammable VOC free basis ( i. e., the concentration of flammable compound i divided by the sum of the concentrations of flammable VOCs and flammable gas) GCFi = Group contribution factor for compound i.

The GCF values for various compounds are listed in Appendix 3.10 of the CH TRU Payload Appendices. Record the MLEL ( Section 4 of the Data Sheet).

4. Calculate and record the sum of the concentrations of the flammable gas in the innermost confinement layer and the flammable VOCs in the innermost confinement layer ( Section 4 of the Data Sheet).

5. Compare the sum of the flammable gas and flammable VOC concentrations within the innermost confinement layer to the calculated MLEL. If the sum of the flammable gas and VOC concentrations is less than or equal to the MLEL, then the container may be shipped if compliance with all other transportation requirements is demonstrated.

If the sum of the flammable gas and VOC concentrations exceeds the MLEL, the container may be reassessed for compliance with transportation requirements through the evaluation of a payload with different shipping categories or dunnage containers. If the sum of the flammable gas and VOC concentrations exceeds the MLEL and the container is not reassessed, the container shall be reconfigured or mitigative measures shall be adopted.

6. In the case of an overpack configuration with multiple containers ( drums in an SWB or TDOP) that consist of one or more overpacked payload container( s), the HNF 2600, REV 15 Page 145 of 281 5/ 11/ 2005 HANFORD SITE TRANSURANIC WASTE CERTIFICATION PLAN configuration must be assessed under Section 4.7.1 and Appendix 2.4 of the CHTRU Payload Appendices.

If the above relevant limits are met, the payload container satisfies the test category criteria. If the Data Sheet is used to document compliance, then the Data Sheet is signed by the Transportation Certification Official. If compliance is determined using a verified/ validated software package, then the necessary data are stored electronically and the Transportation Certification Official signs the completed PCTCD or OPCTCD, as appropriate. The payload container qualifies for shipment after verification of all of the transportation parameters. Containers that do not meet the test category criteria are segregated for repackaging or reprocessing.

Procedure for Testing Hanford does not perform this testing.

Implementation of Unified Flammable Gas Test Procedure Long Term Objective The long term objective of the UFGTP is applied to a population of containers with consistent gas generation properties. The long term objective of the UFGTP may be implemented once the required data have been collected through measurement for a subpopulation of these containers. If a bounding FGGR value for compliance determination can be established and shown to be below the maximum allowable FGGR for the population, no further need exists to test every container in the population. If the bounding FGGR value exceeds the maximum allowable FGGR, the population will continue to be processed under the measurement method of the UFGTP. This method is consistent with that used in the determination of dose dependent G values in Appendix 3.3 of the CH TRU Payload Appendices.

Site implementation of the UFGTP long term objective must be documented in site specific programs approved by DOE CBFO and Hanford has no such programs at this time.

4.6.3 Venting and Aspiration <IP_ADDRESS> Requirements Payload containers that have been stored in an unvented condition ( i. e., no filter and/ or unpunctured liner) shall be aspirated for the specific length of time to ensure equilibration of any gases that may have accumulated in the closed container. For payload containers with waste types in packaging configurations that do not generate any flammable gas, aspiration is not required ( i. e., Waste Material Type II. 2). Note: The aspiration requirement is applicable only to containers that have been stored in an unvented condition. The derivation of aspiration times is outlined in Appendix 3.7 of the CH TRU Payload Appendices. HNF 2600, REV 15 Page 146 of 281 5/ 11/ 2005 HANFORD SITE TRANSURANIC WASTE CERTIFICATION PLAN <IP_ADDRESS> Compliance and Verification The following sections describe the three options that are available for determining the required aspiration time. Tables in this section present aspiration times for common packaging configurations.

Project personnel ensure that all containers are properly vented or repackage CH TRU waste into vented containers. Unvented containers will be allowed to aspirate for a period of time determined using one of the options and applicable aspiration tables presented in this Certification Plan. If option 2 or 3 is used to determine aspiration time, project personnel follow headspace gas sampling requirements identified in TRU OP 001 to analyze the headspace gas samples. Analytical personnel determine the concentration of hydrogen in the headspace gas samples in accordance with LA 523 426. The WCO determines the aspiration option used in accordance with WMP 400, Section 7.1.8 and enters the information required to compute the aspiration time in WWIS in accordance with WMP 400, Section 7.1.5.

Refer to Appendix A, column " CH TRAMPAC (& Certification Plan Section, if applicable)" row 5.3, which contains the titles of applicable procedures that implement the requirements of this subsection.

Option 1   Aspiration Time Based on Date of Payload Container Closure Compliance shall be by records and database information. For sites using this option, the steps outlined below shall be implemented to determine the aspiration time for a payload container.

1. The potential shipping category of the payload container shall be known.

2. The duration for which the container has been in a closed condition should be computed from a knowledge of the date of closure of the drum. This closure time should be rounded up to the next highest time period listed in Tables 4.6.3 1, 4.6.3 2, or 4.6.3 3.

3. The required aspiration time corresponding to this closure time shall then be read from the same table under the column for the number of layers of confinement associated with the appropriate container shipping category.

4. The container shall be qualified for shipment only after being aspirated for at least this period of time.

Option 2   Headspace Gas Sampling at the Time of Venting Compliance shall be by measurement of headspace gas concentrations and records. For sites using this option, the steps outlined below shall be implemented to determine the aspiration time for a payload container.

1. The potential shipping category of the payload container shall be known. HNF 2600, REV 15 Page 147 of 281 5/ 11/ 2005 HANFORD SITE TRANSURANIC WASTE CERTIFICATION PLAN 2. At the time of venting, a headspace sample shall be taken from the container headspace ( Option 2A) or from the rigid liner headspace ( Option 2B) and analyzed for the hydrogen concentration.

3. The measured headspace concentration of all hydrogen shall be rounded up to the next highest mole percentage listed in Tables 4.6.3 4, 4.6.3 5, 4.6.3 6, 4.6.3 7, 4.6.3 8, or 4.6.3 9 determined by Option 2A or 2B, as appropriate.

4. The required aspiration time corresponding to this molar percentage shall be read from the same table under the column for the number of layers of confinement associated with the appropriate container shipping category.

5. The container shall be qualified for shipment only after being aspirated for at least this period of time.

Option 3   Headspace Gas Sampling During Aspiration Compliance shall be by direct measurement of the headspace gas concentration. For sites using this option, the steps outlined below shall be implemented to determine the aspiration time for a payload container.

1. The potential shipping category of the payload container shall be known.

2. Prior to measuring the hydrogen concentration in the payload container headspace, the drum shall be vented for at least two weeks.

3. The measured headspace concentration of hydrogen shall be rounded up to the next highest mole percentage listed in Tables 4.6.3 10, 4.6.3 11, or 4.6.3 12.

4. The required aspiration time corresponding to this molar percentage shall be read from the same table under the column for the number of layers of confinement associated with the appropriate container shipping category.

5. The container shall be qualified for shipment only after being aspirated for this period of time. HNF 2600, REV 15 Page 148 of 281 5/ 11/ 2005 HANFORD SITE TRANSURANIC WASTE CERTIFICATION PLAN Table 4.6.3 1 Aspiration Times Based on Date of Drum Closure ( Waste Type Ia)

HNF 2600, REV 15 Page 175 of 281 5/ 11/ 2005 HANFORD SITE TRANSURANIC WASTE CERTIFICATION PLAN 4.7 PAYLOAD ASSEMBLY REQUIREMENTS This subsection describes the procedures that must be followed to assemble a payload approved and qualified for transport in the TRUPACT II in accordance with the CH TRAMPAC.

The parameters described in previous subsections shall be evaluated for selection of a payload.

The CIN number shall uniquely identify the payload container. The content code identifies a payload shipping category per the CH TRUCON document. Whenever applicable, the measured parameters ( weight, fissile material, and the decay heat) shall be checked against the limits after addition of the measurement error, as detailed in previous subsections.

If the container does not meet any of the limits, it shall be rejected from transport, marked, and segregated. If all requirements are satisfied except for the decay heat limit or flammable VOC limits, the container can be assigned to a test category and can be qualified for transport only by the procedure outlined in subsection 4.7.2 of this Certification Plan and consistent with the CHTRAMPAC

Only waste with approved content codes described in the CH TRUCON document may be transported in the TRUPACT II. Shipping categories impose restrictions and requirements on the manner in which a payload can be assembled as follows:

  Payload selection shall be made from only those payload containers that have been approved for shipment.   After all the payload parameters have been quantified and verified and the transport requirements are satisfied, the shipping category must be confirmed.   Individual containers forming a payload within each TRUPACT II shall belong to the same shipping category or equivalent categories allowed by Appendix 2.4 of the CH TRU Payload Assemblies. This permits the management of different waste material types, different payload containers, and different internal packaging configurations. This requirement applies to drums ( including POCs), SWBs, and TDOPs.   Payload containers with different shipping categories may be shipped when each payload container demonstrates compliance with the flammability index ( FI). A payload can be qualified for shipment only if the FI of each payload container is equal to or less than 50,000. If one or more payload containers fail the FI requirements, the payload assembly shall be reconfigured until all payload packages satisfy this requirement. The FI is calculated as the ratio of the actual flammable gas generation rate to the allowable flammable gas generation rate limit multiplied by 50,000.   Transportation parameters of individual payload containers are recorded on the PCTCD or OPCTCD and/ or the TRUPACT II test category payload container data sheets. Separate PCTCD and OPCTCD forms are used for the analytical payload shipping category and the test payload shipping category. ( Examples of these forms are provided in appendices B 1, B 2, and C, respectively.) Information on these forms should be available for each payload container, even if the format is not identical to that shown in appendices B 1 through B 4 and C ( e. g., use of a computer generated form is acceptable provided all required information is included). A payload container may be certified for HNF 2600, REV 15 Page 176 of 281 5/ 11/ 2005 HANFORD SITE TRANSURANIC WASTE CERTIFICATION PLAN transport only if all transportation parameters are in compliance with the CH TRAMPAC. The TCO verifies compliance before containers are authorized for transport.   A TRUPACT II shipment is authorized only if all the transportation requirements are met and verified by the TCO. The transportation parameters of every TRUPACT II shipment are then recorded on the PATCD ( shown in Appendix D). The information on this form must be available for each payload assembly, even if the format is not identical to that shown in Appendix D ( e. g., use of a computer generated form is acceptable provided all required information is included). The shipper shall maintain the shipping records for a minimum period of three years.

All authorized payloads must meet the requirements set forth in the CH TRAMPAC. Data on the parameters for specific payloads are obtained by the methods outlined in this Certification Plan in accordance with the specific limits of the CH TRUCON document. The following subsections describe methods for evaluating the payload container and shipment data against TRUPACT II limits and restrictions. All container and shipment data are entered into WWIS and must be approved by CBFO.

4.7.1 Certification of Individual Payload Containers for Transport in the TRUPACT II ( Analytical Payload Shipping Category)

<IP_ADDRESS> Requirements Generating and storage sites shall qualify an individual payload container for transport in a TRUPACT II under the analytical category by verifying that the container meets the parameter requirements/ limits listed in previous subsections of this certification plan. All parameters noted on the PCTCD or OPCTCD for overpack containers shall be included in any modified version. Data on the parameters for specific payloads shall be obtained by the methods outlined in this Certification Plan, be consistent with the CH TRAMPAC and shall be consistent with the information for each parameter provided in the CH TRUCON document.

Individual payload containers must be qualified for transport in a TRUPACT II by verifying that each container meets the requirements and limits for the parameters listed on the PCTCD or OPCTCD for overpacks for the analytical payload shipping category.

<IP_ADDRESS> Compliance and Verification The TCO completes a PCTCD or OPCTCD for analytical category waste in accordance with WMP 400, Section 2.1.5, to qualify an individual payload container for shipping. The TCO signs and dates the PCTCD or OPCTCD after verifying that each container meets the following transportation parameter requirements.

  Container ID and container Bar Code Numbers identification numbers unique to each container and used to track process data and package history   Shipping Category assigned using the corresponding tables in the CH TRUCON document or as approved by the WIPP CH TRU Payload Engineer HNF 2600, REV 15 Page 177 of 281 5/ 11/ 2005 HANFORD SITE TRANSURANIC WASTE CERTIFICATION PLAN   Content Code acquired either from the data package ( preassigned) or by correlating the waste description with the applicable contents code list in the CH TRUCON document   Container Type and Configuration ( e. g., direct load or overpacked or fixed)   obtained by visual inspection, RTR, or VE   Certification Site the location at which transportation takes place ( e. g., the generating site for newly generated waste; the generating or storage site for retrievably stored waste)   CH TRAMPAC/ Transportation Parameters for each payload container, the following criteria must be met:

1. Residual liquids limited to residual amounts less than 1 percent of container volume ( no residual liquids)

2. Sharp/ heavy objects are blocked/ braced/ suitably packaged 3. Nonradioactive pyrophorics are prohibited 4. Radioactive pyrophorics are < 1% by weight 5. Explosives are prohibited 6. Corrosives are prohibited 7. Pressurized containers and compressed gases are prohibited 8. Sealed containers greater than 4 liters are prohibited, except for waste material Type II. 2 packaged in metal cans 9. Rigid liner ( if present) is punctured/ filtered 10. Flammable VOCs are limited to not more than 500 ppm per payload container or be evaluated for meeting the requirements of the test category ( see Subsection <IP_ADDRESS> of this Certification Plan)

11. Radiation dose rates are less than or equal to the limits specified in Subsection <IP_ADDRESS>, Table 4.4 2 of this Certification Plan.

12. Filter Identification   Information obtained by visual inspection includes filter vent identification of both supplier and date of installation, lot number, or unique serial number. The type and number of filters will be documented depending on container type. For fixed configurations ( e. g., pipe overpacks), the filter information shall be documented for both the payload containers ( e. g., inner pipe component and outer drum).

13. A single, unvented heat sealed bag is allowed provided the requirements of Appendix 6.13 of the CH TRU Payload Appendices are met. HNF 2600, REV 15 Page 178 of 281 5/ 11/ 2005 HANFORD SITE TRANSURANIC WASTE CERTIFICATION PLAN Measured Transportation Parameters   Weight the maximum weight limit for the appropriate payload container type shall be recorded. Loaded weight of each payload container obtained from the data package. Container weight ( plus error at one standard deviation) is obtained from the data package ( an error is assigned to the container weight in accordance with the project method) and total weight plus error compared against the allowable limit for each payload container. If overpacked, the maximum allowable limit applies to the outermost payload container.   Decay Heat ( Plus Error) obtained and recorded from the data package. Decay heat plus error ( at one standard deviation) is compared against the allowable decay heat limit per payload container for applicable shipping category. For mixed category and/ or taking credit for dunnage, the decay heat limit is marked N/ A, and the flammability index is used and recorded.   Fissile Mass ( Plus Two Times the Error) obtained from NDA data report ( fissile mass calculated by combining isotopic inventory data and 239Pu FGE for each radionuclide in the waste, plus error ( at one standard deviation) is assigned to the fissile mass for the appropriate payload container. If overpacked, the allowable limit applies to the outermost payload container.   Curie Limits   obtained and recorded from the NDA data reports, as applicable, for only S200 POCs. The measured curie value plus measurement error ( one standard deviation) must meet the appropriate limit.

Unvented Waste Parameters   Aspiration Method ( Option 1, 2a, 2b, or 3) confirms that the requirements on aspiration time for containers that have been closed ( e. g., not vented with an approved filter vent) for a period of time are met. Aspiration methods must be determined and recorded. Aspiration methods include:

1. Required Aspiration Period The required aspiration time for the selected option shall be noted or determined in accordance with Appendix 3.7 of the CH TRU Payload Appendices. If the hydrogen concentration indicates that aspiration is not needed, a zero shall be entered.

2. Container Closed Time ( Option 1)   the period of time a payload container has been unvented in storage. That time is recorded.

3. Headspace H2 Concentration ( Option 2a, 2b, or 3)   The H2 concentration measured in the headspace of a payload container is recorded.

4. Aspiration Period/ Aspiration Table   Aspiration time selected shall be limited to the value specified by appropriate aspiration table. If H2 concentration indicates the aspiration is not needed, a zero is recorded on the PCTCD. This is not applicable for test category containers or overpacked containers. HNF 2600, REV 15 Page 179 of 281 5/ 11/ 2005 HANFORD SITE TRANSURANIC WASTE CERTIFICATION PLAN 5. Time Container Vented   Indicates the number of days the payload container has vented. The time that the container was vented must comply with the prescribed aspiration period recorded above.

Overpack Payload Container Parameters Identification Parameters   Overpack Container ID Number/ Bar Code Number   The site specific ID number is unique to each container of waste and provides a means for tracking process data records and package history.   Payload Shipping Category Number   The governing shipping category for the overpack configuration shall be determined by selecting the payload shipping category of the container being overpacked with either the lowest decay heat limit or the lowest hydrogen/ flammable gas generation rate limit. These values shall be determined by consulting the appropriate PCTCDs completed for the payload container( s) to be overpacked.   Decay Heat Limit   The maximum allowable decay heat per payload container for the governing payload shipping category of the overpacked configuration. If mixing shipping categories within an overpack, indicate that the decay heat limit for the payload is not applicable. Mixing of shipping categories shall meet the requirements of Section 4.7.4.   Hydrogen/ Flammable Gas Generation Rate Limit   the governing flammable gas generation rate limit for the overpack is recorded either from an approved shipping category or from the test category container data sheet. If mixing shipping categories within an overpack, indicate that the hydrogen/ flammable gas generation rate limit for the payload is not applicable. Mixing of shipping categories shall meet the requirements of Section 4.7.4.   Overpack/ Overpacked Container Type   Select the appropriate overpack container type and overpacked container type. The payload container shall be one of the approved types in one of the following authorized configurations.

1. SWB with 55 gallon drum( s) ( SWB overpack)   Waste packaged in 55 gallon drum( s) overpacked in one SWB ( up to four 55 gallon drums per SWB)

2. TDOP with 55 gallon drums   Waste packaged in 55 gallon drum( s) overpacked in one TDOP ( up to ten 55 gallon drums per TDOP)

3. TDOP with SWB   Waste packaged in one SWB overpacked in one TDOP ( one SWB per TDOP)

4. TDOP with SWB overpack   Waste packaged in 55 gallon drum( s) overpacked in one SWB ( up to four 55 gallon drums per SWB) overpacked in one TDOP ( one SWB per TTDOP). HNF 2600, REV 15 Page 180 of 281 5/ 11/ 2005 HANFORD SITE TRANSURANIC WASTE CERTIFICATION PLAN 5. TDOP with 85 gallon drum overpack( s)   Waste packaged in one 55 gallon drum overpacked in one 85 gallon drum overpacked in one TDOP ( up to six 85 gallon drum overpacks per TDOP)

6. TDOP with 85 gallon drum( s) Waste packaged in 85 gallon drum( s) overpacked in one TDOP ( up to six 85 gallon drums per TDOP).

7. TDOP with bin overpack   Waste packaged in one bin overpacked in one SWB overpacked in one TDOP ( one bin overpack per TDOP).

8. 85 gallon drum with 55 gallon drum ( 85 gallon drum overpack).

  Weight Limit   The maximum allowable weight limit for the appropriate overpacking payload container type ( i. e., SWB or TDOP) shall be recorded. The limit applies only to the outermost payload container.   Fissile Mass Limit   The maximum allowable fissile mass limit for the appropriate payload container type ( i. e., SWB or TDO) shall be recorded.   Certification Site   The certification site shall be recorded at the location at which transportation certification occurs.   Content Code   The content code from the data package for the payload container shall be approved.

CH TRAMPAC Transportation Parameters Compliance information for the CH TRAMPAC transportation parameters shall be obtained from the data package for the payload container. The TCO indicates compliance and documents it on the OPCTCD as appropriate. The following criteria shall be met.
