| Description | Inspection Scope The inspectors reviewed operability determinations for the following degraded or non- conforming conditions based on the risk significance of the associated components and systems: Unit 1 Anchor Darling double disk gate valves evaluation resulting from NRC Information Notice 2017- 03 on July 13, 2017 Unit 1 fire protection system functionality during a fire water header break on July 20, 2017 Impact on Unit 1 SSST 1A from nearby fire water header break on July 20, 2017 Unit 1 EDG exhaust piping not protected from tornado- generated missiles on July 25, 2017 Unit 1 degraded main steam valve room high energy line break door on July 26, 2017 Unit 2 inoperable DRPI impact on verifying operability of control rod F10 on August 25, 2017 Unit 1 EDG 1 -2 building exhaust damper missing louver on September 22, 2017 The inspectors evaluated the technical adequacy of the operability determinations to assess whether TS operability was properly justified and the subject SSC remained available such that no unrecognized increase in risk occurred. The inspectors compared the operability and design criteria in the appropriate sections of the TS s and UFSAR to FENOCs evaluations to determine whether the SSCs were operable. The inspectors confirmed, where appropriate, compliance with bounding limitations associated with the evaluations. Where compensatory measures were required to maintain operability , the inspectors determined whether the measures in place would function as intended and were properly controlled by FENOC. 11 b. Findings 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 SSCs 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 EDG s exhausts from tornado generated missiles. FENOC documented the condition adverse to quality in their CAP under condition report 2017 -07550 and took immediate compensatory actions. 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 and is not issuing enforcement action and is allowing continued reactor operation |
