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.

Calculated spectrum-averaged cross sections are presented for all of the reactions in the International Reactor Dosimetry File (IRDF-82) using the ten benchmark neutron fields that were distributed with IRDF-82. Comparisons to experimentally measured spectrum-averaged cross sections are presented for the 252Cf and 235U thermal fission spectra. This comparison shows that the difference between the measured and calculated spectrum averages is still much larger than the experimentally quoted uncertainties. This indicates that more precise knowledge of these spectra and further evaluations are still needed.
