K-25 K-25 was the codename given by the Manhattan Project during World War II for the project to produce enriched uranium for atomic bombs using the gaseous diffusion method. Originally the codename for the product, over time it came to refer to the project, the production facility located at the Clinton Engineer Works in Oak Ridge, Tennessee, the main gaseous diffusion building, and ultimately the site. When it was built in 1944, the four-story K-25 gaseous diffusion plant was the world's largest building, with over 1640000 sqft of floor space and a volume of 97500000 cuft .

South Holston Dam South Holston Dam is a hydroelectric and flood control dam on the South Fork Holston River in Sullivan County, in the U.S. state of Tennessee. It is the uppermost of three dams on the South Fork Holston owned and operated by the Tennessee Valley Authority, which built the dam in the 1940s as part of efforts to control flooding in the Tennessee River watershed. On October 21, 1950 the valve gate closed and water began backing up to create South Holston Reservoir. Work began on the dam in December 1941, but in November 1942, the War Production Board requested that the operation be suspended because of a shortage of critical materials. Work did not resume until July 1, 1947. The dam now impounds the South Holston Lake of 7550 acre , which extends northeastward across the Tennessee-Virginia state line.

SM-1 SM-1 was a 2-megawatt nuclear reactor developed by the United States Atomic Energy Commission for the US Army Nuclear Power Program (ANPP) in the mid-1950s. The compact "package" reactor was designed to produce electricity and generate heat for remote military facilities. The first, the SM-1, served as the Army's primary training facility to train reactor operations personnel from all three services (Army, Navy and Air Force). In 1954, the Department of Defense placed the US Army in charge of all military nuclear power plants except those used for propulsion by the US Navy. The Army's Chief of Engineers established the US Army Engineer Reactors Group in April 1954, and decided to construct the SM-1 facility at the Corps of Engineers headquarters at Fort Belvoir, Virginia, about 18 miles south of Washington, D.C.. About 800 personnel were trained on the SM-1 during its operational life, from 1957 to 1973. The power plant was shut down in March 1973, and is monitored within a "restricted access" section of the post. Inspectors enter the shut-down operations control room every decade or so, and the building may be demolished "about 50 years" after the reactor core was removed, possibly around 2030.

Aylesworth Creek Aylesworth Creek is a tributary of the Lackawanna River in Lackawanna County, Pennsylvania, in the United States. It is approximately 4.9 mi long and flows through Carbondale Township, Mayfield, and Archbald. The watershed of the creek has an area of 6.73 sqmi . Part of the creek is impaired by abandoned mine drainage and/or resource extraction. The creek tends to be slightly acidic, but its iron, manganese, and aluminum concentrations do not need reduction to meet its total maximum daily load requirements. Its watershed is in the Appalachian Mountain section of the ridge and valley physiographic province. The headwaters of the creek are in the Moosic Mountains. The rock formations in the watershed mainly consist of interbedded sedimentary rock and sandstone.

Divine Strake Divine Strake was the official designation for a large-yield, non-nuclear, high-explosive test that was planned for the Nevada National Security Site, formerly the Nevada Test Site. Following its announcement, the test generated great controversy, centering on two issues: its potential value in developing a nuclear "bunker buster" warhead, and the possibility that the mushroom cloud generated by the explosion could carry large amounts of radioactive dust deposited at the Test Site over years of nuclear testing.

Vermont Yankee Nuclear Power Plant Vermont Yankee was an electricity generating nuclear power plant, located in the town of Vernon, Vermont, in the northeastern United States. It generated 620 megawatts (MWe) of electricity at full power. The plant was a boiling water reactor (BWR), designed by General Electric. It operated from 1972 until December 29, 2014, when its owner Entergy shut down the plant. In 2008, the plant provided 71.8% of all electricity generated within Vermont, amounting to 35% of Vermont's electricity consumption. The plant is on the Connecticut River, upstream of the Vernon, Vermont Hydroelectric Dam and used the reservoir pool for its cooling water.

Frankfort Dam The Frankfort Dam impounds Marsh Stream near the center of Frankfort, Maine. Built in 1905 out of granite probably quarried at the nearby Mount Waldo Granite Works to provide power to local mills, it served for many years as a key element of the local economy. Its spillway has been adapted for use by a hydroelectric power station. The dam was listed on the National Register of Historic Places in 2003.

Alva B. Adams Tunnel The Alva B. Adams Tunnel is the principal component of the largest transmountain water project in Colorado, the Colorado-Big Thompson Project (C-BT). The tunnel transfers water from the western slope of the Colorado River drainage to the eastern Front Range of Colorado. The tunnel is 13.1 mi long and has a concrete lined diameter of 9.75 ft . The tunnel drops 109 ft in elevation along its length and runs in a straight line under the Continental Divide from west to east passing under Rocky Mountain National Park. At its deepest point, the tunnel is about 3,800 ft below the surface of the mountain peaks. Construction began on 15 June 1940, but was suspended as a result of World War II priorities, from the end of 1942 to August 1943. The tunnel was holed through on 31 March 1944, an event that was broadcast throughout the United States by NBC Radio. The tunnel was posthumously named for its chief advocate, US Senator Alva B. Adams.

Clay Pit Pond Clay Pit Pond, also known as Claypit Pond, is a pond in the Boston suburb of Belmont in Middlesex County, Massachusetts situated between Concord Avenue and Belmont High School. It is a man-made pond, excavated as the source of clay for industrial brick-making on the site from 1888 to 1926. The Pond was formed in 1933 when the Wellington Brook was redirected to flood the site, making it an essential part of the drainage system for much of Belmont.

Army Nuclear Power Program The Army Nuclear Power Program (ANPP) was a program of the United States Army to develop small pressurized water and boiling water nuclear power reactors to generate electrical and space-heating energy primarily at remote, relatively inaccessible sites. The ANPP had several accomplishments, but ultimately it was considered to be "a solution in search of a problem." The U.S. Army Engineer Reactors Group managed this program and it was headquartered at Fort Belvoir, Virginia. The program began in 1954 and had effectively terminated by about 1977, with the last class of NPP operators graduating in 1977. Work continued for some time thereafter either for decommissioning of the plants or placing them into SAFSTOR (long term storage and monitoring before decommissioning). The current development of small modular reactors has led to a renewed interest in military applications.

Fort Gibson Dam The Fort Gibson Dam is a gravity dam on the Grand (Neosho) River in Oklahoma, 5.4 mi north of Fort Gibson. The purpose of the dam is flood control and hydroelectric power production. It was authorized by the Flood Control Act of 1941 and construction began the next year. During World War II construction was suspended and it recommenced in May 1946. In June 1949, the river was closed and the entire project was complete in September 1953 with the operation of the last of the power plant's four generators. The dam and power rights originally belonged to the Grand River Dam Authority but were seized by the U.S. Army Corps of Engineers in 1946.
