| event text = At 0453 CST on 01/02/2006, the Plant Shift Superintendent (PSS) was notified that steam was observed leaking from the C-337A Position 1 West Autoclave. A 14 ton cylinder containing 0.711 % U235 assay uranium hexafluoride had been heating (TSR [Technical Safety Requirement] Mode 5) for approximately 5 minutes when the leak was observed. The autoclave pressure containment boundary is a TSR system required to be operable per TSR 2.2.3.1, 'Autoclave High Pressure Isolation System (HPIS),' when the autoclave is in Mode 5. The autoclave was placed in Mode 2, 'Autoclave Out-of-Service' in accordance with LCO Required Actions 2.2.3.1.C. | | event text = At 0453 CST on 01/02/2006, the Plant Shift Superintendent (PSS) was notified that steam was observed leaking from the C-337A Position 1 West Autoclave.

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. | This event is reportable as a 24 hour event in accordance with 10CFR 76.120(c)(2)(i).
