Recent Results at the Tritium Systems Test Assembly

Recent Experiments at the TSTA have demonstrated successful operation of the integrated exhaust gas processing loop. In these experiments the final subsystem, the cryogenic compound pumps, was integrated into the loop. These tests were conducted with a tritium inventory of about 110 g and a processing rate of about 1 kg per day—full scale for a fusion machine such as ITER. The tests demonstrated a workable-exhaust gas processing system which could be used for ITER. Other recent tests include testing on a single shot tritium pellet injector developed and fabricated at ORNL.
