At 0219 CST, on 12-08-08 the Plant Shift S … At 0219 CST, on 12-08-08 the Plant Shift Superintendent (PSS) was notified that the C-333 Unit 6 Cell 5 UF6 Release Detection (PGLD) System would not test fire during routine testing. Operators found that the READY, MANUAL, and POWER lights for this system were properly illuminated. This PGLD System contains detectors that cover only C-333 Unit 6 Cell 5 which was operating above atmospheric pressure. TSR 2.4.4.1 requires that at least the minimum number of detector heads in the cell are operable during steady state operations above atmospheric pressure. With the Unit 6 Cell 5 PGLD system inoperable, none of the required cell heads were operable. This PGLD System was declared inoperable, TSR LCO 2.4.4.1.B.1 was entered and a continuous smoke watch was put in place within one hour.</br>Engineering has determined, by analyzing the failed component, that the system would not have been able to perform its intended safety function when this condition was discovered. This event is reportable as a 24 hour event in accordance with 10CFR76.120(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.</br>The NRC Senior Resident Inspector has been notified of this event.</br>As of the time of the report, the problem has been corrected and the system returned to service.rected and the system returned to service. +
