At 0937 CDST, on 09/23/08 the Plant Shift … At 0937 CDST, on 09/23/08 the Plant Shift Superintendent (PSS) was notified that C-315 (tails withdrawal facility) had lost power due to a fault on a 14 KV feeder. As a result of the power loss, the C-315 High Voltage Process Gas Leak Detection (PGLD) System was rendered inoperable. This PGLD System contains detectors that cover the C-315 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. This PGLD System was declared inoperable. TSR LCO 2.3.4.4.A.1 was entered and a continuous smoke watch was put in place within one hour. 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-315 facility. The High Voltage PGLD system was tested, and the system was declared operable. Power was restored at 1039 hours and the High Voltage PGLD System was declared operable at 1118 hours.</br>The NRC Resident Inspector has been notified of this event.</br>PGDP Assessment and Tracking Report No. ATR-08-2371; PGDP Event Report No. PAD-2008-29; Responsible Division: Operations.2008-29; Responsible Division: Operations. +
