At 0130 [hrs. CDT] on 05-09-04, the Plant Shift Superintendent (PSS) was notified of a failure of the C-316 High Voltage UF6 Release Detection System. The High Voltage UF6 detection system was disabled by a computer malfunction. This High Voltage UF6 Release System is designed to activate alarms in the event of a UF6 release. The PSS declared the system inoperable and TSR [Technical Safety Requirement] LCO 2.3.4.4.A actions were implemented to post a continuous smoke watch in the affected area. The event is reportable as a 24 hour event, as required by 10 CFR 76.120(c)(2)(i); 'An event in which equipment is disabled or fails to function as designed when 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 preestablished safe condition after an accident.' The equipment was required by TSR to be available and operable and no redundant equipment was available to perform the required safety function. | At 0130 [hrs.
