Title | |
Event Description | On 03/16/11, at 1647 [EST], Peach Bottom Atomic Power Station Unit 2 declared the High Pressure Coolant Injection system inoperable for a condition found during testing which could cause the system to malfunction when swapping suction sources. While lined up to the suppression pool suction flow path, unsatisfactory results were obtained while venting for system fill verification, indicating potential voiding of a portion of the pump discharge piping. Unit 2 HPCI remains available while aligned to its normal suction, the condensate storage tank.
