The inspectors identified a non-cited viol … The inspectors identified a non-cited violation of 10 CFR 50, Appendix B, Criterion XVI, Corrective Action, for the licensees failure to correct a condition adverse to quality by failing to implement adequate corrective actions to address degradation in the performance of the 2D RHR room cooler. On July 17, 2009, the 2D RHR room cooler thermal overload failed due to high mechanical vibrations, which the licensee failed to identify and correct prior to a subsequent failure on August 19, 2009. This finding was entered into the licensees corrective action program as PER 261728. The inspectors determined that the licensees failure to implement adequate corrective actions after the 2D RHR motor trip on July 17, 2009 was a performance deficiency. The performance deficiency was determined to be more than minor because it was associated with the Equipment Performance attribute of the Mitigating Systems Cornerstone in that it adversely affected the reliability of the 2D RHR room cooler to respond to initiating events. The inspectors determined that the finding was of very low safety significance because it did not result in inoperability of a safety function for greater than the allowed technical specification outage time. The inspectors determined that this finding directly involved the cross-cutting area of Problem Identification and Resolution, component of the Corrective Action Program and aspect of Appropriate and Timely Corrective Actions because the licensee did not implement appropriate and timely corrective actions to resolve a condition adverse to quality. Specifically, the problem with the 2D RHR room cooler was not adequately addressed after the motor trip on July 17, 2009.sed after the motor trip on July 17, 2009. +
