Finding

Title

Failure To Maintain Design Control of the Emergency Diesel Generators Voltage Regulator Cabinets

Description

The inspectors identified a non-cited violation of 10 CFR Part 50, Appendix B, Criterion III, Design Control, associated with the licensees failure to assure that the applicable design basis requirements associated with the emergency diesel generators 1 and 2 voltage regulator cabinets were correctly translated into the plant design. Specifically, the licensee did not have an analysis that demonstrated that the emergency diesel generators voltage regulator cabinets would remain operable following a design basis seismic event due to their close proximity to the emergency diesel generator switchgear cabinets. The licensee entered this deficiency into their corrective action program for resolution as Condition Report CR-CNS-2012-05618. The licensee subsequently performed an operability evaluation and determined emergency diesel generators would be operable following a design basis seismic event. The licensees failure to maintain design control of the emergency diesel generators 1 and 2 voltage regulator cabinets was a performance deficiency. The performance deficiency is more than minor and is therefore a finding because it was associated with the design control attribute of the Mitigating Systems Cornerstone, in that the initial plant design failed to analyze for a potential seismic interaction between cabinets; as such, this affected the associated cornerstone objective to ensure availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The inspectors evaluated the finding using Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process For Findings At-Power. The inspectors determined that the finding is of very low safety significance (Green) because the finding: (1) was not a deficiency affecting the design or 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 technical specification allowed outage time, or two separate safety systems out-of-service for longer than its technical specification allowed outage time; and (4) did not represent an actual loss of function of one or more nontechnical specification trains of equipment designated as high safety-significance in accordance with the licensees maintenance rule program. This finding did not have a cross-cutting aspect because the most significant contributor did not reflect current licensee performance.
