| Title | Untimely Corrective Action for the \\\'B\\\' Spent Fuel Pool Cooling Pump |
| Description | A Green, self-revealing non-cited violation (NCV) was identified of 10CFR50 Appendix 8, Criterion XVI, Corrective Action was identified when Exelon did not take timely corrective action to address an identified degrading trend in the performance of the \\\'8\\\' spent fuel pool cooling pump, resulting in the pump\\\'s performance falling below the required action criteria of its in-service test and being declared inoperable. Exelon repaired the pump by replacing the impeller and performed a satisfactory in-service test (IST) on December 8, and entered the issue into the corrective action program. The NCV was not similar to the examples cited in IMC 0612 Appendix E, but the inspectors determined it was more than minor because it was associated with the Structures, Systems and Components (SSC) performance attribute of the barrier integrity cornerstone objective to provide reasonable assurance that the physical design barriers protect the public from radionuclide releases caused by accidents or events by maintaining the functionality of the spent fuel pool cooling system. The inspectors determined this issue was of very low safety significance (Green) because the issue did not result in a loss of cooling to the spent fuel pool where operator or equipment failures could preclude restoration of cooling prior to pool boiling, did not result from fuel handling errors that caused damage to fuel clad integrity or a dropped assembly, and did not result in a loss of spent fuel pool inventory greater than ten percent of the fuel pool volume. The performance deficiency had a cross-cutting aspect in the area of human performance, work control H.3(b) because Exelon did not effectively coordinate work activities by implementing actions to communicate, coordinate and cooperate with each other during activities in which interdepartmental coordination is necessary to assure plant and human performance. |
