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.

An extensive study has been carried out to evaluate possible use of the perfluoropolyether fluids, obtained from hexafluoropropylene photo-oxidation and specially purified and selected, as lubricants or vacuum-working fluids, in the presence of UF6. Some physicochemical properties are reported and the results of the tests experienced on perfluoropolyether cuts put into contact with UF6 at different conditions for a long aging time at high temperature in the presence of some typical engineering materials. The results allowed a verification of the long-term compatibility of the perfluoropolyether special fractions against UF6 at temperatures up to 130°C.
