Title | Failure to Promptly Identify and Correct a Condition Adverse to Quality |
Description | The inspector identified a non-cited violation of 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Action, associated with the licensees failure to promptly identify and correct a condition adverse to quality. Specifically, following a turbine trip/load reject and subsequent reactor scram, reactor vessel level rose to the point of receiving a high level isolation signal (Level 8), and the licensee failed to identify this as an unexpected condition. The licensee entered this issue into the corrective action program as Condition Report CR-RBS-2012-07250. The failure to promptly identify and correct a condition adverse to quality was a performance deficiency. The performance deficiency is more than minor, and is therefore a finding because it affected the Mitigating Systems Cornerstone objective to ensure availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Using Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process (SDP) For Findings At-Power, the inspector determined that the finding is of very low safety significance (Green) because the finding: (1) was not a deficiency affecting the design or qualification of a mitigating structure, system or component, and did not result in a loss of operability or functionality; (2) did not represent a loss of system and/or function; (3) did not represent an actual loss of function of at least a single train for longer than its technical specification allowed outage time, or two separate safety systems out-of-service for longer than its technical specification allowed outage time; and (4) did not represent an actual loss of function of one or more nontechnical specification trains of equipment designated as high safety-significance in accordance with the licensees maintenance rule program. The finding has a cross-cutting aspect in the area of problem identification and resolution associated with the corrective action component, because the licensee failed to periodically trend and assess information from the corrective action program and other assessments in the aggregate to identify programmatic and common cause problems. |
