Title | Safe Shutdown Procedure Implementation |
Description | The inspectors identified an Unresolved Item (URI) concerning safe shutdown procedure implementation. The fire protection safe shutdown procedures specified, as a precaution, that the procedures were to be followed only in the event that normal or emergency procedures were insufficient. The training provided to operators reinforced this procedural expectation. The inspectors were concerned that this precaution effectively established an entry condition, which could delay or preclude operators from entering safe shutdown procedures during a fire. The inspectors were concerned that operators may not perform necessary actions in sufficient time in the event of a severe fire. In response to the inspectors concerns, the licensee initiated AR 01258932, NRC FP Triennial 2011 NRC Question Regarding T-0, and AR 01272652. This issue is a URI pending further assessment of how operators would respond to ensure that 10 CFR Part 50, Appendix R, Section III.L performance goals are met in the event of a fire. The assessment will likely include development of fire scenarios which would challenge operator decision making abilities using existing procedures, and evaluation of how operators would respond under such scenarios either through table top review with the licensee or simulator demonstration. |
