LEAKAGE OF WATER FROM GASKETED JOINTS PROPOSED FOR THE HWCTR-PART II AND PUMP MECHANICAL SEAL VAPOR LEAKAGE
Technical Report
·
OSTI ID:4842999
The average leakage rate was less than 0.3 pound per year per linear inch of gasket when mockups of typical joints proposed for the reactor vessel and the isolated coolant loops of the HWCTR were subjected to temperature and pressure cycling. The joints, which were exposed to deionized light water, were cycled about 100 times from 70 deg C and atmospheric pressure to 250 deg C and pressures of 1500 psig for the vessel joints and 750 psig for the joints designed for the isolated coolant loops. The average leakage of water vapor from a pump mechanical seal was less than 1.4 lb/yr during a five-month period. The pump circulated deionized water at 260 deg C and 850 psig. (auth)
