ne total of these capacit, losses amounted to the equivalent of 6.3 full power hours (FPH,,). Other generation losses (those which would occur even at continuous full thermal power operation) netted to -0.9 FPH,,. (Negative net losses result from cooler-than-design (seasonal) circulation water temperatures at the condenser inlet).

De isolation signal originated from a RCiC room area differential temperature switch and continued for approximately 38 seconds before resetting itself. Operators dispatched to the RCIC toom continned that a stear. leak did not exist. The saspect switch, which had been installed in September 1997, was replaced and the isolation was cleared. Folicwing the isolation, extensive testing failed 10 indicate a cause for the event. He isoladon is considered to be spurious, here wano effect on plant operation or safety During the time the isolation was present, RCIC was
. inoperable, llowever, RCIC h not considered an emergency core cooling system and credit is not taken for RCIC to mitigate any accidents described in the safety analysis. LERN9712 Licensing Action Summary:
