Jones, T. D.

At the beginning of the second quarter of 1978, the Shippingport Atomic Power Station was in operation with the 1A, 1B, 1C, and 1D reactor coolant loops and the 1AC and 1BD purification loops in normal service. The remainder of the expended PWR Core 2 was in storage under shielding water in the deep pit of the Fuel Handling Building. Twelve Core 2 blanket fuel assemblies were shipped offsite this quarter. 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 procedures. During the quarter, the station was operated for the Duquesne Light Company system grid including base load and swing load operation. Thirty-nine swing load operations have been performed on the LWBR Core this quarter to meet the LWBR core operating plan of 50 during this operating phase. The LWBR Core has generated 5282.8 EFPH from start-up through the end of the quarter. The generator load factor this quarter was 71.6%.
