The inspectors identified an NCV at Unit 2 … The inspectors identified an NCV at Unit 2 of Title 10 of the Code of Federal Regulations (10 CFR) Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, because CENG did not assure that the replacement of cells in battery 2C were prescribed and performed by appropriate procedures which resulted in degraded accuracy of test results and potential degradation of safety-related battery cells. In response to this issue, CENG generated CR-2013-005235 and initiated actions to evaluate replacing the new cells. This finding is more than minor because it was associated with the equipment performance attribute of the Mitigating Systems cornerstone and affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. In accordance with IMC 0609.04, Initial Characterization of Findings, and Exhibit 2 of IMC 0609, Appendix A, The Significance Determination Process for Findings At-Power, issued June 19, 2012, the inspectors determined this finding is of very low safety significance (Green) because the performance deficiency was not a design or qualification deficiency, did not involve an actual loss of safety function, did not represent actual loss of a safety function of a single train for greater than its TS allowed outage time, and did not screen as potentially risk-significant due to a seismic, flooding, or severe weather initiating event. This finding has a cross-cutting aspect in the area of Human Performance, Decision-Making component, because CENG did not use conservative assumptions in decision making. Specifically, CENG did not monitor the cells in storage, question the adequacy of the discharged cells, charge the cells prior to installation, or fully evaluate the implications of the test and recharge results.ications of the test and recharge results. +
