| Title | Failure to ldentify a Non-Conservative Technical Specification following Revision to River Stage Discharge Analysis |
| Description | An NRC identified non-cited violation (NCV) of 10 CFR 50, Appendix B, Criterion XVl, Corrective Actions, was identified because Exelon did not identify and correct a condition adverse to quality regarding the impact of a revised river stage discharge analysis result on Technical Specifications (TSs). Specifically, Exelon did not recognize that the revised river discharge analysis resulted in a lower flow-based river shutdown level, resulting in a non-conservative TS. The inspectors determined this was a performance deficiency because Exelon personnel did not promptly identify and correct a condition adverse to quality regarding the non-conservative TS 3.14.2. Exelon entered the issue into their corrective action program under lR 1272726. The finding is more than minor because the finding is associated with the protection against external factors attribute of the Initiating Event cornerstone to limit the likelihood of those events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. The inspectors evaluated the finding in accordance with IMC 0609, Attachment 4, Phase 1 - Initial Screening and Characterization of Findings, and determined it was of very low safety significance (Green) because the issue did not increase the likelihood of a fire or internal/external flood event. This finding has a cross-cutting aspect, as described in IMC 0310, in the area of Problem ldentification and Resolution, Corrective Action Program, because Exelon failed to identify issues completely, accurately and in a timely manner commensurate with their safety significance. Specifically, Exelon failed to identify the non-conservative TS in a timely manner. |
