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.

The QPANDA nodal models, which are embodied in the SIMULA TE-3 code, have been extensively tested and benchmarked. Comparisons to quarter-core PDQ depletion calculations demonstrate the high degree of accuracy with which power distributions are predicted, even though SIMULA TE-3 contains no user-adjusted normalizations. The QPANDA pin power reconstruction model is introduced, and comparisons (versus CASMO colorset and PDQ quarter-core calculations) demonstrate that accurate pin power distributions are obtained by modulating the intranodal power distributions with single-assembly CASMO pin power distributions. Comparisons of SIMULATE-3 calculations to measured reactor fission rate integrals are presented. Also, the overall accuracy of the CASMO-3 cross sections, the QPANDA nodal model, and the QPANDA pin power reconstruction model is demonstrated.
