| Title | Failure to Report Conditions that Could have Presented Fulfillment of a Safety Function |
| Description | The inspectors identified a Severity Level IV noncited violation of 10 CFR 50.73, Licensee Event Report System, with three examples in which the licensee failed to submit licensee event reports within 60 days following discovery of an event meeting the reportability criteria. First, on April 10, 2008, Wolf Creek submitted Licensee Event Report 2008-002-00 under 10 CFR 50.73(a)(2)(i)(B) which is operation prohibited by technical specifications but failed to make a report for a loss of safety function per 10 CFR 50.73(a)(2)(v) for the same event in which both trains of the emergency core cooling system were inoperable on February 13-14, 2008. Second, Wolf Creek filed Licensee Event Report 2008-004-00 on June 6, 2008 under 50.73(a)(2)(iv)(A) for an event that caused automatic start of an emergency diesel during a loss of offsite power on April 16, 2008. No report was made under 50.73(a)(2)(v) for an event or condition that could have prevented a safety function due to the loss of offsite power. Third, on April 10, 2008, Wolf Creek filed Event Notification Report 44131 under 10 CFR 50.72(b)(3)(ii)(B) based on a possible trip of all four containment coolers. The notification was later retracted. The inspectors found insufficient evidence to show that the containment coolers would not trip and concluded the event should have been reported under 10 CFR 50.73(a)(2)(v). All three issues are collectively captured in Condition Report 15318. 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 the 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 the emergency core cooling system, the offsite power system, and the containment heat removal system P.1(c) (Section 4OA3) |
