| Title | Adequacy of Airlock Ball Valve Maintenance |
| Description | The inspectors identified an Unresolved Item (URI)05000440/2008003-01 associated with containment airlock maintenance. Maintenance was conducted on an upper containment airlock door seal system to replace a ball valve on March 26, 2008. The airlock seal failed on June 1, 2008, and the ball valve was found in a degraded condition with significant metal wear on the ball and stem interface. The licensee continued to review the issue at the end of the inspection period. Because the ball valve was found significantly degraded and had failed in less than three months after installation, the inspectors remained concerned whether appropriate procedures were implemented associated with the ball valve maintenance on March 26. The inspectors plan to reevaluate this URI following completion of the licensees investigation |
