| Title | High Pressure Coolant Injection Temporarily Inoperable |
| Event Description | The following information was obtained from the licensee via facsimile (licensee text in quotes):
Unit 2 High Pressure Coolant Injection (HPCI) [was] declared inoperable due to a loose control power fuse clip associated with the HPCI Pump Suction from Suppression Pool Valve HV-055-212041. The loose clip resulted in loss of control power to this DC motor operated valve and therefore rendered the HPCI system inoperable. The fuse clip has been replaced and the HPCI system returned to an operable status. This report is being made pursuant to 10CFR 50.72(b)(3)(v)(D) as a condition that at the time of discovery could have prevented the fulfillment of the safety function of a system that is needed to mitigate the consequences of an accident. The licensee will notify the NRC Resident Inspector. |
