FAILURE TO ADDRESS ALL THE EFFECTS OF EXTERNAL FLOODING SCENARIOS
"On August 28, 2013, Monticello Nuclear Generating Plant (MNGP) was notified of the NRC's final significance determination for a finding involving the failure to maintain a procedure addressing all of the effects of an external flooding scenario on the plant. Specifically, MNGP failed to maintain flood Procedure A.6, 'Acts of Nature,' such that it could support the timely implementation of flood protection activities within the 12 day timeframe credited in the design basis as stated in the updated safety analysis report.
"The finding is not a current safety concern. On February 15, 2013, actions were completed to reduce the flood mitigation plan timeline to less than 12 days by developing an alternate plan for flood protection features, pre-staging equipment and materials, improving the quality of the A.6 procedure, and preplanning work orders necessary to carry out Procedure A.6 actions.
"The NRC Resident Inspector has been notified."
