| Title | Licensee-Identified Violation |
| Description | 10 CFR 50, Appendix B, Criterion XVI, Corrective Action, required, in part, that measures shall be established to assure that conditions adverse to quality, such as defective equipment, were promptly corrected. Contrary to this, the licensee determined that it had failed to take adequate measures consistent with industry operating experience and vendor recommendations to assure that an identified equipment defect associated with MSRV stem thread degradation was corrected, which subsequently resulted in a failure of a Unit 2 MSRV to properly lift and reseat. This condition was identified as a result of performing a TS required surveillance procedure. This finding was entered into the licensees corrective action program as PER 174596 and PER 173480 for the associated root cause analysis. This finding was also determined to be of very low safety because it did not result in exceeding the TS limit for unidentified RCS operational leakage of 5 GPM, nor did the finding affect other mitigation systems resulting in a total loss of their safety function |
