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.

High-order PN calculations of critical radii are carried out for both bare and reflected spheres in the one-speed model and also of critical half-thicknesses for slabs. Results are compared with published data where possible. It is found that PN calculations diverge for sufficiently large N, although good results are still obtained provided that the critical radius is not too small.
