Title	Safety Equipment Failure - Process Gas Leak Detection System
Event Description	At 1030, on 3-30-07 the Plant Shift Superintendent was notified of the failure of the C-333A Process Gas Leak Detection (PGLD) detector head YE-613-21. Detector head YE-613-21 is located in the piping trench between the autoclaves. The trench detector heads are scheduled to be replaced at a six month interval. Operators were performing an "as-found" test on the head prior to scheduled replacement. The detector head did not alarm as required when smoke was applied during the test. The Process Gas Leak Detection system is required to be operable according to TSR 2.2.4.1. This event is reportable as a 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> event in accordance with 10CFR 76.120(c)(2)(l). 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. The YE-613-21 detector head was replaced approximately 6 months ago and was last known to be functional approximately one month ago after some wiring tests were conducted in the area of the detector head. The permittee is conducting failure cause analysis to determine failure mode and possibly identify when failure occurred. The NRC Senior Resident Inspector has been notified of this event.
