| Title | Expansion Joint Degradation Resulted in River Water Inoperability |
| Description | The inspectors identified a Green NCV of TS 5.4.1 Procedures for FENOCs failure to adequately implement and maintain a replacement program for expansion joints installed in safety related systems. Specifically, rubber expansion joint REJ-1RW-24B was in service beyond the service life and degraded unacceptably while in service in the Unit 1 river water system. Corrective actions included replacing the expansion joint and addressing expansion joint preventive maintenance issues. FENOC entered the issue into the licensees corrective action program under CR 2012-03347. The finding is more than minor because it is similar to IMC 0612, Power Reactor Inspection Reports, Appendix E, Examples of Minor Issues, example 4.f in that a condition adverse to quality degraded after initial identification and affected the operability of the river water system. This finding is associated with the procedure quality attribute of the Initiating Events cornerstone and affected the cornerstone objective to limit the likelihood of those events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. The inspectors determined the finding did not contribute to both the likelihood of a reactor trip and the likelihood that mitigation equipment or functions would not be available. Therefore, the finding is considered to be of very low safety significance. This finding has a cross-cutting aspect in the area of Human Performance, Resources, because FENOC failed to ensure procedures supported maintaining long term plant safety by minimizing preventive maintenance deferrals |
