| Title | Failure to Evaluate Operability of System Wide Anode Degradation in the Service Water System |
| Description | The inspectors identified a non-cited violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, for the licensees failure to follow Procedure PPM 1.3.66, Operability and Functionality Evaluation, Revision 25-27. Specifically, the licensee failed to evaluate extent of condition and operability of components affected by sacrificial anode degradation in service-water-supplied air-to-water heat exchangers. The licensee entered this issue into their corrective action program as Action Request AR 290553290553 The performance deficiency was more than minor because it affected the equipment performance attribute of the Mitigating Systems Cornerstone objective of ensuring the reliability of systems that respond to initiating events. The inspectors performed an initial screening of the finding in accordance with NRC Manual Chapter IMC 0609, Appendix A, The Significance Determination Process (SDP) for Findings At-Power. Using IMC 0609, Appendix A, Exhibit 2, Mitigating Systems Screening Questions, the inspectors determined this finding is of very low safety significance (Green) because: (1) the finding was not a deficiency affecting the design or qualification of a mitigating system; (2) the finding did not represent a loss of system and/or function; (3) the finding did not represent an actual loss of function of a single train for greater than its technical specification allowed outage time; and (4) the finding does not represent an actual loss of function of one or more non-technical specification trains of equipment designated as high safety-significant in accordance with the licensees maintenance rule program for greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. This finding had a crosscutting aspect in the area of problem identification and resolution associated with the corrective action program component because the licensee failed to periodically trend and assess information related to service water cooled heat exchangers in the aggregate to identify programmatic and common cause problems. |
