Title | Failure to Enter a Steam Leak on Safety Related Main Steam Piping in the Corrective Action Program |
Description | An NRC-identified non-cited violation (NCV) of 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Action, was identified for the licensees failure to adequately identify and correct a steam leak on a safety-related portion of the Main Steam system. The issue was entered into the licensees corrective action program as PIP C-10-3092 to evaluate the leak for operability and establish corrective actions. An E2 work request was also written to repair the leak. The finding was determined to be more than minor because if left uncorrected the steam leak could degrade and exceed the value used in the existing analysis for a Design Basis Steam Generator Tube Rupture and also could affect manual operation of equipment during execution of emergency and abnormal operating procedures. It was determined to be of very low safety significance (Green) using IMC 0609, Appendix H Table 4.1, Containment-Related SSCs Considered for Large Early Release Frequency Implications, due to the small size of the flow element line. This finding had a crosscutting aspect in the corrective action program component of the area of problem identification and resolution because the steam leak was not identified completely, accurately, and in a timely manner (P.1(a)). |
