Finding

Title

Inconsistent Maintenance Rule Evaluations Performed on Containment Isolation Valves

Description

The inspectors found inconsistencies in how LD-4A/B/C valves were scoped in as risk significant or non-risk significant. An evaluation performed in 2008 called the valves risk significant, and an evaluation performed in 2009 called the valves non-risk significant. The difference in scoping would determine if a maintenance rule functional failure existed. Additionally, inspectors found an instance where a maintenance rule evaluation was not performed following an as-found test failure. The licensee entered these into the CAP and was evaluating the inspectors concerns. The inspectors need the results to determine if a performance deficiency existed and if it was more than minor.
