| Title | Failure to Establish Goals and Monitor for a(1) ECCS Room |
| Description | The inspectors identified a noncited violation of 10 CFR 50.65(a)(1) for failure to establish goals for the safety-related room coolers and monitor room cooler performance against those goals. In 2005, residual heat removal pump Room Cooler SGL1OA had accumulated enough unavailability time to move the room cooler function to a(1) status. While dealing with a room cooler replacement schedule that was delayed several times, the licensee decided that a(1) goals did not need to be established until all room coolers were replaced. The inspectors considered this to be a case where no technically justified goals were established. The licensee entered this issue into their corrective action program as Condition Report 2008-3145 which included action to expedite room cooler procurement and replacement. Thisfinding is more than minor because it is consistent with Inspection Manual Chapter 0612, Appendix E, Example 7.a. Specifically, The licensee failed to establish a(1) goals and monitor performance against those goals for the a(1) GL-5 function for 3 years. The inspectors evaluated the significance of this finding and determined that the finding is of very low safety significance because the support function (GL-5) to cool pump rooms does not result in a total loss of any safety function as identified by the licensee probability risk assessment that contributes to external event initiated core damage accident sequences (i.e., initiated by a seismic, flooding, or severe weather event). The finding has a crosscutting aspects in the problem identification and resolution area associated with corrective action program because the licensee failed to take appropriate corrective actions to address this safety issue and the adverse room cooler trends in a timely manner, commensurate with safety significance and complexity P.1(d) |
