Book excerpt: At the beginning of the second quarter of 1980, the Shippingport Atomic Power Station remained shutdown for the normally planned semiannual maintenance and testing program, initiated February 29, 1980. 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 station remained in a cooled down condition until April 8, when a plant heat-up was initiated and completed on April 11, from which time normal operating parameters were maintained. The reactor was operated at low power levels as required for cold and hot planned testing. Base mode operations began on April 19. Swingload operations began May 20 and occurred daily through May 29 with levels ranging down to 30% to 60% power. On May 30, the station underwent a planned shutdown to perform test procedure LWBR-DLCS 64601, Bank Reactivity Worth and Temperature and Power Coefficients of Reactivity at Power. On May 31, criticality was achieved and the station returned to full power. Swingload operations resumed on June 1 and continued daily through the end of the quarter with the exceptions of June 17 and June 30. Swingload levels ranged down to 27.5% to 60% power.
