| Title | High Pressure Coolant Injection (Hpci) System Inoperable |
| Event Description | On 4/22/09 at approximately 1121, during surveillance testing on the High Pressure Coolant Injection (HPCI) System, the associated Primary Containment Isolation valves closed. This isolation rendered the HPCI system incapable of performing its safety function and is, therefore, reportable under 10 CFR 50.72(b)(3)(v). Technical Specification LCO 3.5.1 Condition C had been entered at 0837 to support testing. The cause of the isolation is unknown at this time. Troubleshooting is in progress. LCO 3.5.1 Condition C provides 14 days for restoration of the HPCI System, the plant will remain in the LCO until the cause is determined and any associated repairs have been completed.
A follow-up Licensee Event Report will be filed within 60 days. The NRC Resident Inspector has been notified. |
