Experiments on a ceramic electrolysis cell and a palladium diffuser at the tritium systems test assembly
A ceramic electrolysis cell and a palladium diffuser are developed in Japan and is tested with tritium in Tritium Systems Test Assembly (TSTA) of the Los Alamos National Laboratory, in order to confirm the feasibility as possible upgrades for the fuel cleanup system (PCU). The ceramic electrolysis cell made of stabilized zirconia was operated at 630/sup 0/C for an extended period with a mixture of 3% T/sub 2/O in He carrier gas in the circulation system with oxidizing catalyst bed. The palladium diffuser was tested with circulated pure tritium gas at 280/sup 0/C to verify the compatibility of the alloy with tritium, since the /sup 3/He produced in the metal could cause a degradation. The isotopic effects were also measured for both devices.
