At 1217 CST, on 01-30-09 the Plant Shift S … At 1217 CST, on 01-30-09 the Plant Shift Superintendent (PSS) was notified that C-310 (product withdrawal facility) had lost power due to an electrical fault. As a result of the power loss, the C-310 High Voltage Process Gas Leak Detection (PGLD) System was rendered inoperable. This PGLD System contains detectors that cover the C-310 UF6 condensers, accumulators, and piping heated housing. At the time of this loss of power, these areas were operating above atmospheric pressure. TSR 2.3.4.4 requires that all of detector heads in this system be operable during operations above atmospheric pressure. Power was restored to this PGLD System at 1240 hours, which is within the one hour required by TSR LCO 2.3.4.4.A.1 to enter a continuous smoke watch. This event is reportable as a 24 hour event in accordance with 10CFR 76.120(c)(2)(i). This is an event in which equipment is disabled or fails to function as designed when: a.) the equipment is required by a TSR to prevent releases, prevent exposures to radiation and radioactive materials exceeding specified limits, mitigate the consequences of an accident, or restore this facility to a pre-established safe condition after an accident; b.) 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 c.) no redundant equipment is available and operable to perform the required safety function. Once the source of the fault was identified, power was restored to the C-310 the High Voltage PGLD System and the system was tested.</br>Power was restored at 1240 hours and the system was tested at 1258 hours. The NRC Senior Resident Inspector has been notified of this event.Inspector has been notified of this event. +
