Dear Sir or Madam:
On March 12, 2012, the NRC issued Reference 1 requesting information pursuant toTitle 10 of the Code of Federal Regulations 50.54(f). Enclosure 2 of that letter containsspecific requested Information associated with NTTF Recommendation 2.1 for flooding.By Reference 2 Entergy Operations, Inc. (Entergy) committed to submit the flood hazardevaluation for Arkansas Nuclear One (ANO), Units 1 and 2 as a Category 2 site byMarch 12, 2014.Entergy Operations, Inc.
1448 S.R. 333Russellville, AR 72802Tel 479-858-3110Jeremy G. BrowningSite Vice PresidentArkansas Nuclear One 0CAN031401 Page 2 of 3In September 2013 (Reference 3), Entergy requested the assistance of the NRC toobtain information from three Districts of the United States Army Corps of Engineers(USACE) to support the flood hazard reevaluation at ANO. Pursuant to the guidance inReference 4, Entergy is revising its commitment for submittal of the flood hazardreevaluation report to six months after USACE data is received.Reason for the Delay:The NRC recently notified Entergy that the kickoff meeting with the USACE and theNRC is expected to be scheduled in the near future. Receipt of the USACE informationis not expected for several months subsequent to the meeting.
Proposed Schedule:Subsequent to receipt of the USACE information, six months are necessary to: Complete the Dam Failure calculation. Use Dam Failure calculation as input to complete the Combined Effects calculation. Perform anticipated stepwise model refinements (consistent with the hierarchicalhazard assessment approach) to the Probable Maximum Precipitation, ArkansasRiver Probable Maximum Flood (PMF) flow, and Arkansas River PMF elevation calculations. Perform iterations to the Dam Failure and Combined Effects calculations. Complete flood hazard reevaluation report for submittal.Basis for Acceptability: Preliminary results to date based on publicly available information including theUSACE districts and National Inventory of Dams indicate the flood hazard isexpected be bounded by the current design basis flood level. The NRC has previously determined in their March 2012, 50.54(f) letter that thecurrent regulatory approach and the resultant plant capabilities provide confidencethat an accident with consequences similar to the Fukushima accident is unlikely tooccur in the United States. The NRC letter concluded that continued plant operationand the continuation of licensing activities do not pose an imminent risk to publichealth and safety. The events being analyzed in the flooding hazard reevaluation are beyond theplant's design basis (and licensing basis). The reevaluation results do not constitutean operability concern. The reevaluated flooding hazard is a very low probability event. The timeframe ofthe submittal delay is short relative to the probability of occurrence of the flood eventbeing evaluated.
