Book excerpt: At the beginning of the second quarter of 1979, the Shippingport Atomic Power Station remained shutdown for the normally planned semiannual maintenance and testing program, initiated March 23, 1979. The station was in a cooldown condition at approximately 150/sup 0/F and 300 psig with a steam bubble maintained in the pressurizer and the reactor coolant pumps in slow speed. The reactor plant cooldown heat exchanger was in service to maintain coolant temperature. The 1A, 1B, 1C, and 1D reactor coolant loops and the 1AC and 1BD purification loops remained in service. The remainder of the expended PWR Core 2 was in storage under shielding water in the deep pit of the Fuel Handling Building. The 1A, 1B, 1C, and 1D 991 psig self-actuated steam relief valves remained gagged during the quarter to prevent leakage through the valve seats. Gagging of redundant relief valves is permitted by ASME Code and approved operating procedure. The LWBR Core has generated 10,771.43 EFPH from start-up through the end of the quarter.
