Dear Sir or Madam:
On March 12, 2012, the NRC issued Reference 1 requesting information pursuant to Title 10 of
the Code of Federal Regulations 50.54(f). Enclosure 2 of that letter contained specific
requested Information associated with NTTF Recommendation 2.1 for flooding. By Reference 2
Entergy Operations, Inc. (Entergy) committed to submit the flood hazard evaluation for
Arkansas Nuclear One (ANO), Units 1 and 2 as a Category 2 site by March 12, 2014.
In September 2013 (Reference 3), Entergy requested the assistance of the NRC to obtain
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 in Reference 4, Entergy requested a revision to its commitment for submittal of the flood hazard reevaluation
report to six months after USACE data is received (Reference 5).
By email dated March 24, 2014 (Reference 6), an NRC request for additional information (RAI)
was forwarded to Entergy associated with the revised commitment of Reference 5 as follows:
The NRC staff requests that Entergy provide a more detailed breakdown of the activities and analyses that remain to be conducted, as well as the associated schedule for those activities and analyses. The NRC staff suggests that a Gantt chart or similar format would be an effective means of communicating the schedule information.
The NRC and ANO personnel discussed this request in phone conversation on March 25, 2014.
The NRC suggested ANO review similar information provided to the NRC by the Cooper and
Ft. Calhoun nuclear facilities. Following review, the ANO version of a Gantt chart did not
contain the level of detail provided by the aforementioned facilities. Therefore, remaining
activities were loaded as inputs into a work scheduling database to produce detail similar to that
previously provided to the NRC by other facilities.
The attachment to this letter provides a chart containing the information that Entergy believes provides the necessary response to the RAI.
This letter contains no new regulatory commitment. Should you have any questions concerning
the content of this letter, please contact Stephenie Pyle at 479.858.4704.
I declare under penalty of perjury that the foregoing is true and correct.
Executed on April 14, 2014.
Sincerely,
