Dear Sir:

By letter dated June 15, 2011, Florida Power Corporation (FPC) requested a license amendment to increase the rated thermal power level of Crystal River Unit 3 (CR-3) from 2609 megawatts to 3014 megawatts (Reference 1). In an FPC response to an NRC staff request for additional information associated with the CR-3 Extended Power Uprate License Amendment Request (Reference 2), a regulatory commitment was included to provide, by October 12, 2012, revisions to the main control room (MCR) atmospheric dispersion factors (X/Q) and associated dose results.

The attachment, "List of Regulatory Commitments," to this correspondence revises the content and date of the regulatory commitment included in FPC to NRC letter dated June 29, 2012 (Reference 2); and hereby, supersedes the previous regulatory commitment.

The regulatory commitment is being revised for the following reasons:

• The due date is being revised from October 12, 2012 to December 20, 2012, in part, due to the primary resources performing the necessary analytical work being unavailable for several weeks.

• To more effectively implement the guidance of Regulatory Guide 1.194, "Atmospheric Relative Concentrations for Control Room Radiological Habitability Assessments at Nuclear Power Plants," the input assumptions associated with the MCR X/Q calculations have been re-evaluated and will be revised, as applicable, to more accurately represent the resulting dose to the MCR environment. As a result, additional time is required to revise the input Crystal River Nuclear Plant 15760 W. Powerline Street Crystal River, FL 34428

U.S. Nuclear Regulatory Commission Page 2 of 3 3F1012-07 assumptions and re-perform the MCR X/Q calculations and determine the impact on the associated MCR dose calculations. As applicable, revised input assumptions associated with the MCR X/Q calculations will be provided along with the updated MCR X/Q values.

• The isolation of the MCR from outside air, upon receipt of a MCR intake high radiation signal, and subsequent operation of the Control Room Emergency Ventilation System will[ be credited during a fuel handling accident (FHA). As a result of this additional FIA assumption, the CR-3 Improved Technical Specifications and associated Bases are being revised as necessary to ensure the Control Room Emergency Ventilation System is available during a FHA. The applicable Improved Technical Specifications and Bases changes will be provided along with the revised MCR FHA dose results.

If you have any questions regarding this correspondence, please contact Mr. Dan Westcott, Superintendent, Licensing and Regulatory Programs at (352) 563-4796.
