Title | Inadequate Preventative Maintenance for Safety-Related Circuit Cards |
Description | A self-revealing Green non-cited violation (NCV) of Technical Specification (TS) 6.8.1.a, Procedures and Programs, was identified regarding PSEG failing to adequately establish, implement, and justify the initial replacement frequency for the 1DD481 inverter control circuit cards. As a result, an age-related failure of circuit cards for the safety-related 1E channel D (1DD481) Inverter occurred on December 24, 2013, which caused PSEG to enter an unplanned 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> shutdown TS 3.8.3.1.a.4 for On-site Power Distribution Systems. PSEGs corrective actions include conducting an extensive extent of condition review of first-call preventive maintenances (PMs). The performance deficiency was determined to be more than minor because it was associated with the equipment performance attribute of the Initiating Events cornerstone, and adversely affected the cornerstone objective to limit the likelihood of events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. The inspectors determined that this finding was of very low safety significance (Green) using NRC IMC 0609, Appendix A, The Significance Determination Process (SDP) for Findings At-Power, Exhibit 1 Initiating Events Screening Questions, dated June 19, 2012, because for findings involving support system initiators, i.e. the Loss of a DC [direct current] bus, the result did not involve the complete or partial loss of a support system that contributed to the likelihood of, or cause, an initiating event and affected mitigation equipment. The inspectors determined that there was no cross-cutting aspect associated with this finding because the cause of the performance deficiency occurred more than three years ago, and was not representative of present licensee performance. |
