| Title | Inadequate Instructions for Changing Modes of Operation of the Residual Heat Removal system |
| Description | The inspectors identified a Severity Level IV noncited violation of 10 CFR 50.73, Licensee Event Report System, associated with the licensees failure to submit a licensee event report within 60 days following discovery of an event meeting the reportability criteria as specified. Specifically, on December 8, 2008, the licensee completed analysis of an issue associated with the residual heat removal system which determined that both trains of the system were inoperable when suction side temperature exceeded 249F. Based on the results of this analysis as well as plant operating history, it was determined that the licensee failed to report instances where the system was operated in a condition prohibited by technical specifications, and a loss of safety function of the system existed between March 20, 2008, and December 8, 2008. The licensee entered this issue into their corrective action program as Condition Reports 2009-1261 and 2009-1326 and Action Requests 15244, 17776, and 15306. The inspectors reviewed this issue in accordance with Inspection Manual Chapter 0612 and the NRC Enforcement Manual. Through this review, the inspectors determined that traditional enforcement was applicable to this issue because the NRC\'s regulatory ability was affected. Specifically, the NRC relies on licensee to identify and report conditions or events meeting the criteria specified in regulations in order to perform its regulatory function, and when this is not done, the regulatory function is impacted. The inspectors determined that this finding was not suitable for evaluation using the significance determination process, and as such, was evaluated in accordance with the NRC Enforcement Policy. The finding was reviewed by NRC management and, because the violation was determined to be of very low safety significance, was not repetitive or willful, and was entered into the corrective action program, this violation is being treated as a Severity Level IV noncited violation consistent with the NRC Enforcement Policy. This finding was determined to have a crosscutting aspect in the area of Problem Identification and Resolution associated with the corrective action program in that the licensee failed to appropriately and thoroughly evaluate for reportability aspects all factors and time frames associated with the inoperability of residual heat removal system when suction temperatures were above 249F P.1(c)(Section 2.1) |
