| Title | Failure to Assure Qualification Testing Met Specified Requirements |
| Description | An NRC-identified Green NCV of 10 CFR Part 50 Appendix B Criterion VII was identified for the licensees failure to assure that purchased chillers for the main control room (MCR) and shutdown board room (SDBR) conformed to the procurement documents. Specifically, the equipment qualification documentation provided for the MCR and SDBR chillers did not provide sufficient evidence to reasonably conclude the equipment would be able to perform its active safety function of heat control before, during, and after the analyzed safe shutdown earthquake. The inspectors determined that the licensees failure to meet procurement specification SL M-0024-0 for qualification of MCR and SDBR chillers was a performance deficiency. The cause was reasonably within the licensees ability to foresee and correct and should have been prevented. The performance deficiency was more than minor because, if left uncorrected, the condition had the potential to lead to a more significant safety concern. The main control room chillers were required to assure habitability was maintained for mitigation and control of analyzed accidents. Because no further equipment qualification activities were planned, the capability of the main control room and shutdown board room cooling equipment to withstand an analyzed earthquake would continue to be indeterminate after installation and placement into service. The NRC concluded that the finding was of very low safety significance (Green) because the chillers had not been installed. The inspectors determined that the finding was directly related to the cross-cutting aspect in the area of Problem Identification and Resolution because the licensee did not take effective corrective actions to address issues in a timely manner commensurate with their safety significance (P.3). |
