| Title | Failure to Perform Adequate Surveillance Testing of the Control Room Air Conditioning System |
| Description | The inspectors identified a non-cited violation of 10 CFR Part 50, Appendix B, Criterion XI, Test Control, for the failure of the licensee to perform required surveillance testing of the control room heating, ventilation and air conditioning (HVAC) system. On October 30, 2012, the inspectors identified that the licensees procedures for testing the heat removal capability of the control room HVAC system tested the service water pump house coolers but did not test any components in the control room HVAC system. Following identification of this issue, the shift manager declared Technical Specification Surveillance Requirement 3.7.4.1 missed for both trains of control room HVAC and applied Surveillance Requirement 3.0.3 which allowed the licensee to delay declaring the limiting condition for operation not met for a limited period of time following the performance of a risk assessment. This issue was entered into the licensees corrective action program as Action Request 273408. This performance deficiency was more than minor because it adversely affected the procedure quality attribute of the Barrier Integrity Cornerstone objective to ensure that physical design barriers protect the public from radionuclide releases caused by accidents or events. 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 only represented a degradation of the radiological barrier provided for by the control room. The inspectors determined that this finding did not have a cross-cutting aspect since the decision to test a service water pump house room cooler in place of the control room HVAC cooler was made at the time of improved standard technical specifications implementation around 1998 and was therefore not reflective of current licensee performance. |
