| Title | Failure to Inspect Tube R1C2 of Steam Generator 2 during the Steam Generator Eddy Current Examination in 2007 |
| Description | An NRC identified non-cited violation (NCV) of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, was identified for failure to adhere to steam generator eddy current examination procedures during the 2007 Unit 2 refueling outage. As a result, a tube inspection was missed. The missed tube inspection was completed during a March 2010 inspection and was found to be without significant degradation. The licensee entered the issue into their corrective action program as CR 2010103680.
The inspectors determined that the finding was more than minor because it was associated with the human performance attribute of the Initiating Events cornerstone and affected the cornerstone objective of assuring that physical design barriers protect the public from radionuclide releases caused by accidents or events. Specifically, the failure to adhere to steam generator tube inspection procedures resulted in a missed tube inspection and affected the assurance that barrier integrity was maintained. The finding was determined to be of very low safety significance because subsequent testing of the missed tube in March 2010 did not indicate tube degradation. This finding was determined to not have a cross-cutting aspect associated with it due to the timeframe of the event and that the cause of the event is not indicative of current plant performance. |
