The NRC staff issued Reference 1 on March 12, 2012. Enclosure 1, of Reference 1, contains Requested Actions, Requested Information, and Required Response associated with Recommendation 2.1 for Seismic. , regarding seismic reevaluations, states:

If an addressee cannot meet the requestedresponse date, the addressee must provide a response within 90 days of the date of this information request and describe the alternative course of action that it proposes to take, including the basis of the acceptability of the proposedalternative course of action and estimated completion dates.

Carolina Power & Light Company (CP&L) and Florida Power Corporation (FPC) have determined that they can meet the requested response dates for submitting the Seismic Hazard Evaluation provided that the NRC and industry reach a mutual understanding of critical implementation details associated with calculating the seismic hazard by the end of July 2012. For example, the critical details that need to be mutually understood prior to

United States Nuclear Regulatory Commission RA-12-025 Page 2 commencement of the new seismic hazard evaluations include the elevation(s) at which the hazard/Ground Motion Response Spectrum (GMRS) will be calculated and the development of site amplification factors for sites with limited soil/rock profile data.

Within 60 days of NRC endorsement of the Screening, Prioritization and Implementation guidance, CP&L and FPC will submit: (1) their intention to follow the endorsed guidance, or (2) provide an alternative approach. At that time, CP&L and FPC will assess whether they can meet the submittal deadlines for the Seismic Risk Evaluation and take the appropriate regulatory action.

This letter contains no new regulatory commitments.

If you have any questions or require additional information, please contact Donna Alexander, Manager, Nuclear Regulatory Affairs, at (919) 546-5357.

I declare under the penalty of perjury that the foregoing is true and correct. Executed on June 11, 2012.

Sincerely, Garry Miller Vice President - Nuclear Engineering Progress Energy, Inc.
