| Title | Failure to Evaluate Several Safety Related Relays Installed Beyond Their Design Life |
| Description | A finding of very low safety significance and an associated non-cited violation of Title 10 of the Code of Federal Regulations, Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, was identified by the inspectors for the licensees failure to accomplish procedure EN-AA-203-1001, Operability Determinations/Functionality Assessments, when new degraded or non-conforming conditions adverse to quality were identified. Specifically, the licensee failed to evaluate operability and the acceptability for continued operation when an extent of condition review identified several safety-related time delay relays installed beyond the vendor recommended design life. The licensee documented the inspectors concerns in condition report 02015742. The affected relays were immediately declared operable but non-conforming, and a prompt operability determination and apparent cause evaluation to determine corrective actions were in progress at the end of the inspection period. The performance deficiency was determined to be more than minor because, if left uncorrected, failing to properly assess the operability of degraded or non-conformin
conditions and evaluating the necessity for compensatory measures would have the potential to lead to a more significant safety concern. Because the finding was a qualification deficiency confirmed not to result in loss of operability, the finding screened as very low safety significance (Green). This finding was associated with the crosscutting aspect of identification in the area of Problem Identification & Resolution because the licensee did not identify or capture the extent of the relay aging condition within the corrective action program to ensure that new conditions adverse to quality were properly screened for significance and potential operability impacts.
