Finding

Title

LICENSEE-IDENTIFIED Violation

Description

Title 10 CFR 50.54(hh)(2)(ii) states: Each licensee shall develop and implement guidance and strategies intended to maintain or restore core cooling, containment, and spent fuel pool cooling capabilities under the circumstances associated with loss of large areas of the plant due to explosions or fire, to include strategies in the following area of operations to mitigate fuel damage. On April 13, 2011, while performing procedure reviews as part of industry-wide self-assessments in response to the core damage events at Fukushima Daiichi, Wolf Creek engineers identified two instances of mitigating strategy procedures which did not contain sufficient information to accomplish those strategies successfully. The first example was the ability to refill the refueling water storage tank, and the second example involved flashing the diesel generator field using alternate dc sources. These issues were documented in the licensees corrective action program as Condition Report 37374. The inspectors evaluated these findings under Inspection Manual Chapter 0609, Appendix L, and determined these findings to be of very low safety significance because the findings did not involve unrecoverable unavailability of multiple mitigating strategies such that spent fuel pool cooling, injection to the reactor vessel, or injection to steam generators cannot occur, or unrecoverable unavailability of on-site, self-powered, portable pumping capability, or substantial inability to perform command and control enhancements.
