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.

Formulas for predicting the uncertainty of neutronic performance parameters are derived for three methods: the bias factor method, the adjustment method, and the combined method. The prediction uncertainties are obtained by including both experimental and method errors. The adjustment method, in principle, yields the same uncertainty as the combined method. The derived formulas are applied to a large homogeneous l000-MW(electric) liquid-metal fast breeder reactor core.
