| Title | Failure to Submit a Licensee Event Report for a Condition Prohibited by Technical Specifications Associated with the Essential Raw Cooling Water System |
| Description | The inspectors identified a Severity Level IV, non-cited violation (NCV) of 10 CFR 50.73(a)(2)(i)(B) for the licensees failure to submit a Licensee Event Report (LER) within 60 days for a condition which was prohibited by Technical Specifications (TS). On June 22, 2009 the licensee failed to recognize that they exceeded the limiting condition for operation (LCO) action time of TS 3.0.3 when both trains of the Essential Raw Cooling Water (ERCW) system were made inoperable when a cross connect valve was inadvertently opened and remained in that position for more than nine hours. Subsequent to this, the condition was discovered, TS 3.0.3 was entered, the valve was shut, and TS 3.0.3 was exited. The licensees initial reportability evaluation concluded that the event was not reportable because the ERCW system would have been able to perform its safety function. However, with the 2A and 2B header cross connected, the system did not meet TS 3.7.8 requirements and was inoperable. This evaluation failed to identify that operating for nine hours with the system inoperable exceeded the TS 3.0.3 LCO action time and thus placed the unit in a condition prohibited by TS, which is a reportable event. The licensee entered this issue into their Corrective Action Program as Problem Evaluation Report 314950. The inspectors determined that this issue was subject to Traditional Enforcement because it had the potential to impact the NRCs ability to perform its regulatory function and was not suitable for evaluation using the significance determination process. This Violation matched example nine in Section 6.9.d of the NRC Enforcement Policy and was, therefore, determined to be more than minor and a SL-IV Violation. Cross cutting aspects are not assigned to violations being dispositioned through the traditional enforcement process. |
