| Title | |
| Description | The inspectors identified a finding of very low safety significance and associated non-cited violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, because the licensee failed to follow work orders to properly configure and perform post-maintenance testing (PMT) of the main feedwater regulating valve (MFRV) limit switches. As a result, the limit switches that provide an input into the anticipated transient without scram mitigation system actuation circuitry (AMSAC) were not tested. Specifically, on June 10, 2011, when engineering change EC-12054 for the MFRVs was partially turned over to and accepted by operations for Mode 2 and AMSAC was required to be functioning, the licensee failed to perform a PMT as required by plant procedures. The licensee entered this issue into its corrective action program for evaluation and development of corrective actions. The finding was determined to be more than minor in accordance with IMC 0612, Power Reactor Inspection Reports, Appendix B, Issue Screening, dated December 24, 2009, because, if left uncorrected, the failure to perform PMT could lead to a more significant safety concern. Specifically, the failure to perform PMT of safetyor risk-related components prior to the operational condition for which the equipment was required could result in a latent failure that would only be discovered during a valid demand. This finding has a cross-cutting aspect in the area of human performance, work practices, because the licensee did not appropriately coordinate work activities by incorporating action to address the impact of changes to the activity on the plant and human performance. |
