(Shippingport Atomic Power Station). Quarterly operating report, fourth quarter 1981

Technical Report ·
OSTI ID:5403877
At the beginning of the fourth quarter of 1981, the Shippingport Atomic Power Station was operating with the 1A, 1B, 1C, and 1D reactor coolant loops and the 1AC and 1BD purification loops in service. The 1A, 1B, and 1C 991 psig self-actuated steam relief valves remained gagged during the quarter to prevent leakage through the valve seats. The 1D steam relief valve was removed during the Spring 1980 Shutdown for repairs and a blind flange was installed in its place. Gagging and/or removing of redundant relief valves is permitted by ASME Code and approved operating procedures. At the beginning of the quarter through December 10, the Station was operated for Duquesne Light Company system grid at maximum base load with the exception of one short duration shutdown and three load reduction periods. The station was shutdown on December 11, beginning the 1981 to 1982 Winter Shutdown. The station remained shutdown through the remainder of the fourth quarter.
