| Title | Leak in High Pressure Fire Water System |
| Event Description | At 1143, on 8/28/08, the Plant Shift Superintendent was notified of a large water leak on High Pressure Fire Water system (HPFW) A-12 in building C-333 due to a piping rupture. The HPFW system provides water for fire suppression to the plant's process buildings. A-12 is 1 of 66 HPFW systems in this process building. Leak analysis indicates the HPFW system A-12 would not have been able to perform its intended safety function while the leak was occurring. The leak was determined to be between the process building and the post indicating valve (PIV). The PIV for this system was closed which isolated the leak. Required TSR LCO actions have been and are being performed. This is being reported as an event in which equipment is disabled or fails to function as designed when the equipment is required by a TSR to be available and operable and either should have been operating or should have operated on demand, and no redundant equipment is available.
The NRC Senior Resident Inspector has been notified of this event.
On 8/29/08, the Kentucky Department of Water (KDOW) was notified that approximately 30,000 gallons of recirculating water (RCW) from the HPFW system containing 4 ppm phosphorus residual was discharged through Outfall 9. RCW discharge to Outfall 9 is reportable to KDOW as a bypass of a treatment system that causes an exceedance of a permit limit per 401 KAR 5:065 Section 1(12)(f). The NRC Senior Resident Inspector has been notified of this event. Notified R2DO (Nease) and NMSS EO (Mamish). |
