Shippingport Atomic Power Station. Technical progress report, January 26-July 25, 1982

OSTI ID:6776830

The Shippingport Atomic Power Station was operated with the Light Water Breeder Reactor (LWBR) core primarily at high power levels (base load) throughout the report period, when the LWBR core had achieved 27,747 EFPH. Several brief reductions in power and two brief station shutdowns occurred during this period. Maximum allowable thermal power continued to be 80% of 236.6 MW thermal with reactor coolant flow at 100%, coolant pressure at 1600 psig and average temperature at 521/sup 0/F until June 1, 1982, when the movable fuel assemblies reached their top withdrawal limit of 84 inches at 26,909 EFPH. During subsequent equilibrium xenon power operation, the movable fuel assemblies remained at the 84 inch elevation while the reactor power level was continuously reduced (beginning June 12, 1982) to extend core reactivity lifetime, reaching 69% of full power at the end of the report period.
