Gas Generation Testing of Plutonium Dioxide
Hydrogen and oxygen gas generation rates were measured for purified plutonium oxide (PuO2) powder as a function of water content, specific surface area (SSA), dose rate, and initial fill gas composition. Gas generation rates were found to increase with water content and dose rate and to decrease with specific surface area for given water content. Hydrogen generation rates were similar in air, nitrogen and argon, but oxygen generation rates were greater in nitrogen and argon than in air. The potential for reaching a steady state container pressure for PuO2 of given calcination temperature (i.e., SSA) and water content was evaluated by adding hydrogen to some test vessels and monitoring the effect on container pressure over time
