| Title | Inadequate Special Operating Procedure for Loss of Spent Fuel Pool Cooling |
| Description | A self-revealing Green NCV of TS 5.4.1, Procedures, was identified for NMPNS failure to provide an adequate special operating procedure for loss of SFP cooling. On May 25, 2012, following a loss of SFP cooling, the inadequate procedural guidance delayed restoration of SFP cooling for over two hours during which SFP temperature rose three degrees. NMPNS entered this issue into its corrective action program as CR 2012-004850 to track resolution of this issue. The finding is more than minor because it was associated with the procedure quality attribute of the Barrier Integrity cornerstone objective to provide reasonable assurance that physical design barriers protect the public from radiological release by maintaining functionality of the SFP cooling system. The finding was determined to be of very low safety significance (Green), due to it not being associated with a loss of cooling to the SFP that would have precluded restoration prior to boiling, a fuel handling error, or loss of SFP inventory. This finding has a cross-cutting aspect in the area of human performance, resources, because NMPNS did not ensure that procedures were adequate to ensure nuclear safety. Specifically, the special operating procedure for loss of SFP cooling did not contain adequate guidance either for restoration of a two skimmer surge tank lineup or for starting a SFP cooling pump on a single surge tank. |
