| Title | Failure to Obtain NRC Approval for Changes to Control Room HVAC Requirements |
| Description | The inspectors identified a non-cited violation of 10 CFR 50.59, Changes, Tests, and Experiments, because the licensee failed to obtain a license amendment, pursuant to 10 CFR 50.90, prior to implementing a change to the control room heating, ventilation and air conditioning system (HVAC). Specifically, through the course of several Final Safety Analysis Report amendments, the licensee changed the control room habitability requirements from 75 degrees Fahrenheit (F) 3 degrees F to 85 degrees F effective temperature without obtaining a license amendment. The violation was evaluated using Section 2.2.4 of the NRC Enforcement Policy, because the violation may impact the ability for the NRC to perform its regulatory oversight function. In accordance with the NRC Enforcement Policy, the significance determination process was used to inform the significance of the failure to obtain a license amendment prior to implementing a proposed change to the main control room design requirements. Using Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process (SDP) for Findings At-Power, the inspectors determined the finding was of very low safety significance because the finding does not represent a degradation of the radiological barrier function provided for the control room and does not represent a degradation of the barrier function of the control room against smoke or a toxic atmosphere. Therefore, in accordance with Section 6.1.d of the NRC Enforcement Policy, the significance was determined to be at Severity Level IV, since the impact of the incorrect changes was evaluated as having very low safety significance by the significance determination process. This issue was entered into the licensee\'s corrective action program as AR 280119280119 and therefore, this violation is treated as SL-IV NCV consistent with Section 2.3.2 of the NRC Enforcement Policy. This violation did not have a cross-cutting aspect because it was strictly associated with a traditional enforcement violation |
