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 deuterium exchange reaction between water vapor and hydrogen gas is studied at 1 atm total pressure and temperatures from 150 to 250°C using a commercially available platinum-impregnated alumina catalyst. Below a water vapor pressure of 190 Torr, two reaction processes, an external mass transfer of hydrogen and an adsorption of water vapor on the surface of the catalyst, are involved in the rate limiting transfer step. Above 190 Torr, external mass transfer of hydrogen governs the reaction rate. An activation energy of 1.5 ± 0.6 kJ/mol is obtained for this transfer step.
