| Title | Inadequate Procedure for Fuel Transfer Flange Installation |
| Description | A self-revealing NCV of TS 5.4.1.a, Procedures, was identified when Ginna personnel did not correctly establish procedure RF-401, Fuel Transfer Blind Flange Removal and Installation, Revision 0, by not ensuring that the procedure contained sufficient guidance to ensure that the flange bolts were properly tightened. The bolts were not tightened which resulted in an increase in the containment leakage rate. Ginna\'s corrective actions included revising the procedure to include torque specifications. This finding is more than minor because it is associated with the barrier performance attribute of the Barrier Integrity cornerstone and affects the cornerstone objective to provide reasonable assurance that physical design barriers (fuel cladding, RCS, and containment) protect the public from radionuclide releases caused by accidents or events. The inspectors determined that this finding is of very low safety significance (Green) using IMC 0609, Appendix A, Determining the Significance of Reactor inspection Findings for At-Power Situations. The finding did not represent a degradation of the radiological barrier function provided for the control room, or auxiliary building, or spent fuel pool; the finding did not represent a degradation of the barrier function of the control room against smoke or a toxic atmosphere; the finding did not represent an actual open pathway in the physical integrity of reactor containment (valves, airlocks, containment isolation system (logic and instrumentation) and heat removal components; and the finding did not involve an actual reduction in function of hydrogen ignitors in the reactor containment. Specifically, although the finding resulted in an increase in the containment leak rate, it did not represent an actual open pathway in the physical integrity of reactor containment. This finding had a cross-cutting aspect in the area of human performance, resources, in that the fuel transfer blind flange installation procedure was not complete, accurate and up to-date. Specifically, the procedure did not contain sufficient installation guidance to ensure that the flange-bolts were properly tightened (H.2(c) per IMC 0310). |
