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.

An accurate background cross-section method for nuclear reactor cell homogenization is developed that is based on the very precise moment expansion approximation to the neutron escape probability that we recently suggested. The moment expansion approximation is so devised to properly generalize the equivalence relation that the background cross-section method attains a high accuracy to <1% error for each individual resonance, yet still preserves the very features of universality and simplicity of Bondarenko's method.
