| Title | Failure to Report Conditions That Could Have Prevented Fulfillment of a Safety Function |
| Description | The inspectors identified a non-cited violation of 10 CFR 50.73(a)(2)(i)(b) for the licensees failure to submit a licensee event report upon discovery that a condition prohibited by technical specifications had existed in the preceding three years. On April 18, 2011, the licensee issued calculation GK-06-W, SGK05A/B Class 1E Electrical Equipment Rooms A/C Units, Single Unit Operation Capability, Revision 2. This calculation concluded that with one of the two air conditioning units inoperable, the use portable fans and the opening of doors was required to maintain vital switchgear rooms below the maximum operability limits. The calculation further concluded that even with these compensatory actions, required temperatures could be maintained only if the temperature of all surrounding areas remained below 78F. Calculation GK-06-W thus demonstrated that a single cooler was incapable of maintaining the switchgear rooms within technical specification limits, without compensatory actions. Because one of the two air conditioning units had been out of service on multiple occasions during the preceding three years with no compensatory actions taken, the condition was reportable. The licensee entered this finding in its corrective action program as condition report 53452. The failure to submit a licensee event report was a performance deficiency. The team evaluated this performance deficiency using the NRCs significance determination process (SDP) and determined that it was of minor safety significance. It is therefore not associated with a finding or assigned a color. However, performance deficiencies which impact the NRCs regulatory ability are processed using traditional enforcement separately from the SDP evaluation. 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. When this is not done, the regulatory function is impacted. Therefore, the team determined that this performance deficiency was most appropriately processed using traditional enforcement. Using the Enforcement Policy and the available risk information, the inspectors concluded that this violation is a traditional enforcement violation of Severity Level IV. |
