| Title | Licensee-Identified Violation |
| Description | The licensee identified a violation of 10 CFR 50 Appendix B, Criterion XVI, Corrective Action, which requires, in part, that measures shall be established to assure that conditions adverse to quality, such as deficiencies, defective material and equipment, and non-conformances are promptly identified and corrected. Contrary to this requirement, while performing ultrasonic examinations on the reactor pressure vessel head during the spring 2012 refueling outage as required by 10 CFR 50.55a(g)(6)(ii)(D), the licensee failed to identify an unacceptable indication in Nozzle 49 that overlapped the J-groove weld and exhibited characteristics of primary water stress corrosion cracking. This finding was determined to be of very low safety significance because subsequent visual and volumetric examinations performed did not detect any leakage and sizing of the indication determined that structural integrity of the vessel head was not compromised. Additionally, the licensee reanalyzed 100% of the spring 2012 inspection data and did not discover any further missed indications. The licensee entered this condition in their corrective action program as Action Request 00606317. |
