| Title | Failure to Perform Technical Specification Surveillance Requirements on the Control Room Air Conditioning System |
| Description | The inspectors identified a non-cited violation of Technical Specification 3.7.11, Control Room Air Conditioning System (CRACS), for failure to perform the surveillance requirements specified for the control room air conditioning system. Surveillance Requirement 3.7.11.1 requires the licensee to verify that each control room air conditioning system train has the capability to remove the assumed heat load once every 18 months. The activities that the licensee was crediting to meet the requirement were not adequate because they did not actually verify heat load removal capability. The licensee entered Surveillance Requirement 3.0.3 for a missed surveillance, performed a risk assessment, and will verify that each control room air conditioning system train has the capability to remove the assumed heat load within 18 months. The licensee entered this issue into the corrective action program as Callaway Action Request 201207859. The inspectors determined that the failure to perform sufficient testing to satisfy a technical specifications surveillance requirement is a performance deficiency. The performance deficiency was more than minor because it impacted the structures, systems, and components and barrier performance attribute for the control room and auxiliary building and the Barrier Integrity Cornerstone objective to provide reasonable assurance that the radiological barrier remains functional. Using Inspection Manual Chapter 0609, Appendix A, Exhibit 3, Barrier Integrity Screening Questions, the finding was determined to be of very low safety significance (Green) because it did not represent an actual degradation of the barrier function of the control room to protect the operators inside from smoke or a toxic atmosphere. The issue has no cross-cutting aspect associated with it because it is not indicative of current licensee performance. |
