Title | Feed Facility Autoclave O-Ring Failure |
Event Description | 08-18-07 at 0210 in the X-342 , Feed Facility, Autoclave #1, 10 minutes into the heating cycle (mode II) experienced an air leak past the Viton O-ring. The steam was secured and autoclave shell opened 30 minutes later. Inspection of the Viton O-ring resulted in the discovery of a 3/8" separation of splice joint. A pressure decay was performed to determine if the O-ring would have performed its 'Q' function. The test failed resulting in a 24 hr. event.
This was reported under 10CFR76.120(c)(2)(i). The licensee will notify the NRC Resident Inspector. |
