| Title | Failure to Incorporate Design Requirements for Switchgear Room Cooling |
| Description | The team identified a non-cited violation of 10 CFR Part 50, Appendix B, Criterion III, Design Control, associated with the licensees failure to fully incorporate applicable design requirements into the plant design. Specifically, since initial construction the licensee has failed to incorporate a ventilation system for the vital switchgear rooms that was capable of maintaining room temperature within design requirements under all design conditions. This issue does not represent an immediate safety concern because the licensee has compensatory measures in place to maintain room temperatures while corrective actions to resolve the issue are being implemented. This issue was entered into the licensees corrective action program as CR 2013 9804. The failure to fully incorporate applicable design requirements is a performance deficiency. The performance deficiency was determined to be more than minor, and therefore a finding, because it affected the design control attribute of the Mitigating Systems Cornerstone, and it directly affected the cornerstone objective to ensure availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Using Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process (SDP) for Findings At-Power, dated July 1, 2012, the finding was determined to have very low safety significance (Green) because it: (1) was not a deficiency affecting the design and qualification of a mitigating structure, system, or component, and did not result in a loss of operability or functionality; (2) did not represent a loss of system and/or function; (3) did not represent an actual loss of function of at least a single train for longer than its allowed outage time, or two separate safety systems out-of-service for longer than their Technical Specification allowed outage time; and (4) did not represent an actual loss of function of one or more non-Technical Specification trains of equipment designated as high safetysignificance in accordance with the licensees maintenance rule program. This finding has a cross-cutting aspect in the area of problem identification and resolution, associated with the corrective action program component, because the licensee did not thoroughly evaluate the problem and, consequently, the resolution did not identify the extent of cause as necessary. |
