Finding

Title

Licensee-Identified Violation

Description

Technical Specification 3.7.2 requires that four main steam isolation valves and their associated actuator trains shall be operable. Technical Specification 3.7.2, Limiting Condition for Operation, Condition A, requires that with one main steam isolation valve with a single actuator train inoperable, that the main steam isolation valve actuator train be restored to operable status within 7 days. Contrary to the above, between July 31, and October 27, 2007, main steam isolation Valve 181 actuator Train A was found to be inoperable during surveillance test Procedure 73ST-9SG01, \"MSIVs Inservice Testing,\" Revision 32. The licensee identified air leakage between the four-way valve and the main steam isolation valve actuator due to maintenance personnel failing to install an air port O-ring. This issue has been entered into the licensee\'s corrective action program as PVAR 3083549, and significant CRDR 3087163. The finding is of very low safety significance because it did not result in a loss of system safety function, an actual loss of safety function of a single train for greater than its Technical Specification allowed outage time since actuator Train B was available, or screen as potentially risk significant due to a seismic, flooding, or severe weather initiating event.
