10 CFR 50, Appendix B, Criterion III, Design Control, requires, in part, that measures shall be established to assure that the applicable regulatory requirements and the design basis for structures, systems, and components are correctly translated into specifications, drawing, procedures, and instructions. Contrary to the above,
FENOC failed to correctly translate the design basis for protection against
tornado-generated missiles into their specifications and procedures. Specifically,
FENOC did not adequately protect Unit 1 and Unit 2s
main steam safety and atmospheric dump valve exhausts from
tornado-generated missiles. Additionally,
FENOC did not adequately protect Unit 2s component cooling pumps and spent fuel from
tornado-generated missiles by failing to include in their procedures actions for closing the tornado doors in the event of a tornado. The inspectors evaluated
FENOCs immediate compensatory measures, which included verifying that procedures are in place and training is current for performing actions in response to a tornado. Because this violation was identified during the discretion period covered by
Enforcement Guidance Memorandum 15-002, Revision 1,
Enforcement Discretion for
Tornado Missile Protection non-compliance (
ML16355A286) and because
FENOC has implemented compensatory measures, the NRC is exercising
enforcement discretion, is not issuing enforcement action, and is allowing continued reactor operation.
