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.

Calculations of neutron wave propagation across a temperature discontinuity in graphite using a multigroup approach are reported. Diffusion, as well as thermalization properties of the medium, are investigated near the interface. As the interface is crossed from the higher to the lower temperature region, a depletion of sub-Bragg neutrons is observed. There is a buildup of neutrons as one crosses the interface from the lower to the higher temperature side.
