ENS 40547 | 26 February 2004 08:38:00 | The High Pressure Coolant Injection (HPCI) system had been removed from service to perform planned maintenance and testing. During post-maintenance testing, the HPCI gland seal condensate pump tripped due to a blown control power fuse. The maintenance scope did not include the pump or its power supply. The fuse was replaced and the surveillance completed satisfactorily. Investigation into the cause of the failure is ongoing. HPCI remains inoperable in support of additional pre-planned testing. The licensee notified the State and the NRC Resident Inspector. |
