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 (MWt) to 3014 MWt. (Reference 1) This correspondence provides supplemental information to the CR-3 Extended Power Uprate (EPU) license amendment request (LAR) #309 as a result of discussions between FPC and the NRC staff during an NRC audit of the CR-3 EPU safety analyses at the AREVA NP, Inc. offices in Lynchburg, VA during the week of June 11-15, 2012.

Attachment A, "CR-3 LOCA Summary Report - EPU/ROTSG/Mark-B-HTP, Revision 4," is provided to support the NRC staff review of the EPU LAR. As noted in the FPC to NRC letter dated March, 19, 2012, "Crystal River Unit 3 -10 CFR 50.46 Notification of Change in Peak Cladding Temperature for Large Break Loss of Coolant Accident Analysis," two estimated adjustments in the large break loss of coolant accident analysis result in a net change in the fuel peak cladding temperature (PCT) of zero. (Reference 2) The first PCT adjustment is due to-an Crystal River Nuclear Plant ADD 15760 W. Powerline Street Crystal River, FL 34428

U.S. Nuclear Regulatory Commission Page 2 of 4 3F0712-03 error in the blow down model control variable that affected the Emergency Core Cooling System bypass calculation. The second PCT adjustment is due to changes in core cooling when the upper plenum column weldments are modeled.

These error adjustments are not explicitly included in the CR-3 EPU LOCA Summary Report contained in Attachment A. Additionally, the CR-3 EPU LOCA Summary Report (Attachment A) does not include a discussion related to thermal conductivity degradation and associated burnup-dependent uncertainties related to the PCT-limited LOCA analyses. This additional discussion is provided in Response SNPB 1-2 in Attachments A and C of the FPC to NRC letter dated June 18, 2012, "Crystal River Unit 3 -

Response to Request for Additional Information to Support NRC Nuclear Performance and Code Review Branch (SNPB) Technical Review of the CR-3 Extended Power Uprate LAR (TAC No.

ME6527)." (Reference 3)

Attachment B, "Technical Report ANP-3114(P): CR-3 EPU - Feedwater Line Break Analysis Sensitivity Studies, Revision 0 (Proprietary)," provides additional sensitivity studies related to the feedwater line break (FWLB) accident analysis performed for the CR-3 EPU to support the CR-3 license basis change request to revise the Reactor Coolant System pressure acceptance criterion for the FWLB accident consistent with the criterion in NUREG-0800, "Standard Review Plan," Section 15.2.8, "Feedwater System Pipe Break Inside And Outside Containment (PWR)," (Reference 1, Attachment 1).

Attachment B contains information that is considered proprietary. AREVA NP, Inc., as the owner of the proprietary information, has executed the affidavit provided in Attachment C and states that the identified information has been classified as proprietary, is customarily held in confidence, and not made available to the public. AREVA NP, Inc. requests the identified proprietary information be withheld from public disclosure in accordance with the provisions of 10 CFR 2.390(a)(4).

Attachment D, "Technical Report ANP-3114(NP):

CR-3 EPU -

Feedwater Line Break Analysis Sensitivity Studies, Revision 0 (Non-proprietary)," is a non-proprietary copy of the FWLB analysis sensitivity studies with the proprietary information redacted.

Attachment E, "Technical Report ANP-3052: CR-3 EPU Feedwater Line Break Analysis with Failure of First Safety Grade Trip, Revision 2," is provided to support the NRC staff review of the EPU LAR. The updated FWLB analysis with the first safety grade trip failed was re-evaluated to incorporate the model and limiting conditions defined in the FWLB sensitivity studies (Attachments B and D) and supersedes the FWLB report transmitted in the FPC to NRC letter dated October 25, 2011, "Crystal River Unit 3 - Feedwater Line Break Overpressure Protection Analysis to Support NRC Reactor Systems Branch Acceptance Review of the CR-3 Extended Power Uprate LAR and LAR Approval Schedule (TAC No. ME6527)." (Reference 4)

The information provided by this correspondence contains no new regulatory commitments and does not change the intent or the justification for the requested EPU license amendment. FPC has determined that this supplemental information to the CR-3 EPU LAR does not affect the basis for concluding that the proposed license amendment (Reference 1) does not involve a Significant Hazards Consideration. As such, the 10 CFR 50.92 evaluation provided in the June 15, 2011 submittal remains valid.
