The core involved was intended to be used in the Able detonation, during the Crossroads series of nuclear weapons testing. Slotin's experiment was said to be the last conducted before the core's detonation and was intended to be the final demonstration of its ability to go critical. After the accident, it needed time to cool. It was therefore rescheduled for the third test of the series, provisionally named Charlie, but this was cancelled due to the unexpected level of radioactivity after the underwater Baker test and the inability to decontaminate the target warships. The core was eventually melted down and reused in a later core.
