10 CFR 50, Appendix B, Criterion III, states in part that measures shall be established to assure that applicable regulatory requirements and the design basis, as defined in 50.2 and as specified in the license application, for those structures, systems, and components to which this appendix applies are correctly translated into specifications, drawings, procedures, and instructions.
10 CFR 50, Appendix B, Criterion III further states that these measures shall include provisions to assure that appropriate quality standards are specified and included in design documents and that deviations from such standards are controlled. Contrary to this requirement, from original plant licensing to October 26, 2012, design basis requirements for the Unit 1/2 Blockhouse, Unit 3 Blockhouse, and the 230 kV relay house werent adequately translated into specifications. The licensees failure to perform an adequate heat load analysis impacted the functionality of safety related equipment in the Unit 1/2 Blockhouse, Unit 3 Blockhouse, and the 230 kV relay house during certain design basis events. This condition was not greater than Green because the limited amount of hours per year above 90 degrees, the slow heatup allowing operator recovery, and the availability of the availability of the SSF and the Lee line limited the more significant sequences to those caused by Tornado or Fire initiators which have low initiating event frequencies. This violation was entered into the licensees corrective action program as
PIP O-12-10969.
