A self-revealing finding was identified fo … A self-revealing finding was identified for the failure of engineering personnel to follow procedures and adequately evaluate an identified adverse condition for corrective actions associated with containment isolation valve UV002 as required by Procedure 90DP-0IP10, Condition Reporting and Procedure 86DP-0EE01, Reliability Centered Maintenance Based System Reviews. Specifically, the licensee identified during a cause analysis performed in 1997 and by a system review conducted in 2004 and 2007 that the failure of containment isolation valve UV002 could result in a reactor trip, but failed to take any corrective actions. This issue was entered into the licensee\'s corrective action program as Condition Report Disposition Request 3411547 which included corrective actions to evaluate the condition in accordance with station procedures and plan a modification to eliminate the adverse condition associated with containment isolation valve UV002.The finding was more than minor because it affected the design control attribute of the Initiating Events Cornerstone, and affected the cornerstone objective to limit the likelihood of those events that upset plant stability and challenge critical safety function during shutdown as well as power operations. Using Manual Chapter 0609.04, Phase 1 Initial Screening and Characterization of Findings, the finding was determined to have very low safety significance because the finding did not contribute to both the likelihood of a reactor trip and mitigating equipment or functions would not be available. This finding was evaluated as not having a crosscutting aspect because the performance deficiency is not indicative of current performance. is not indicative of current performance. +
