Development of a partitionable accumulator with pressure tolerance for the cryogenic hydrogen system at J-PARC

Tatsumoto, Hideki; Aso, Tomokazu ; Otsu, Kiichi; Kawakami, Yoshihiko

A partitionable accumulator with pressure tolerance has been developed to achieve a stable long-term operation for the J-PARC cryogenic hydrogen system. The accumulator has a bellows structure to spontaneously change the volume according to the pressure fluctuation, which is mainly caused by the proton beam operation. The developed accumulator had been installed in 2014 and uniformly expands and contracts with no hysteresis. It is confirmed through a 300-kW proton beam operation that the pressure rise agrees with the predicted value and becomes lower than that for the previous one. It is confirmed that the performance satisfies the requirements.
