No impact from Savannah River radioactive wasps
The news is abuzz with recent news stories about four radioactive wasp nests found at the Department of Energy’s Savannah River Site in South Carolina. The site has been undergoing cleanup operations since the 1990s related to the production of plutonium and tritium for defense purposes during the Cold War. Cleanup activities are expected to continue into the 2060s.

A scheme, which initially requires only partial convergence of the source iteration, is introduced into boiling water reactor (BWR) void feedback iterations. By reducing the number of source iterations within the early void iterations where nuclear parameters are uncertain, the entire iterative procedure is accomplished more efficiently, the computer time is reduced, and final convergence is guaranteed. The scheme has proven very successful in conducting BWR fuel management and control rod programming calculations.
