Renewed License No. DPR-27 Amendment No. 234

SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 229 TO RENEWED FACILITY OPERATING LICENSE NO. DPR-24 AND AMENDMENT NO. 234 TO RENEWED FACILITY OPERATING LICENSE NO. DPR-27 FPL ENERGY POINT BEACH, LLC POINT BEACH NUCLEAR PLANT, UNITS 1 AND 2 DOCKET NOS. 50-266 AND 50-301

1.0 INTRODUCTION

By application to the U.S. Nuclear Regulatory Commission (NRC) dated December 14, 2006 (Ref. 1), as supplemented by letter dated June 13, 2007 (Ref. 2 ), the Nuclear Management Company, LLC (NMC, the licensee at the time of the submittal), requested changes to the Technical Specifications (TSs) for the Point Beach Nuclear Plant (PBNP), Units 1 and 2. The supplement dated June 13, 2007, provided additional information that clarified the application, did not expand the scope of the application as originally noticed, and did not change the staffs original proposed no significant hazards consideration determination as published in the Federal Register on January 16, 2007 (72 FR 1780). FPL Energy Point Beach, LLC has since become the current licensee, following a license transfer that occurred on August 28, 2007.

Therefore, from hereon in this safety evaluation (SE) any correspondence from NMC will be referred to as correspondence from the licensee.

The proposed amendment would revise TS 5.6.5, "Reactor Coolant System (RCS) Pressure and Temperature Limits Report (PTLR)". The revision would add the FERRET Code as an approved methodology for determining RCS pressure and temperature (P-T) limits for PBNP, Units 1 and 2.

During its review of the proposed license amendment discussed herein, the NRC staff determined that the RCS P-T limits for PBNP exceeded the approved limit of 25.59 effective full power years (EFPYs) of operation for Unit 1. The approved EFPYs of operation for Unit 1 corresponded to October 30, 2003. Because actual operation for Unit 1 did not match predicted operation, Unit 1 did not actually exceed its EFPYs of operation until February 2004.1 In a letter to the NRC dated November 7, 2003 (ML033240022), the licensee stated that they planned to issue new P-T curves prior to Unit 1 reaching 25.59 EFPYs. The licensee did not submit a revision of the PTLR until December 14, 2006. The results of the latest fluence calculations, and the fact that the P-T limits, the limiting RPV beltline values, and the material 1

In safety evaluation (SE) dated July 23, 2001, Unit 2 had an EFPYs, corresponding to October 1, 2008. The NRC staff did not find that the Unit 2 reactor vessel had exceeded its EFPYs.

properties for Unit 1 remain unchanged, demonstrate that the Unit 1 reactor vessel was not outside its safety limits. The vessel was fully capable to perform the required service.

2.0 REGULATORY EVALUATION

The regulatory requirements for pressure vessel fluence calculations are specified in General Design Criteria (GDCs) 30 and 31 (Ref. 4). In March 2001, the NRC staff issued Regulatory Guide (RG) 1.190, Calculational and Dosimetry Methods for Determining Pressure Vessel Neutron Fluence (Ref. 5). The NRC staff has approved vessel fluence calculation methodologies which satisfy the requirements of GDC 30 and 31 and adhere to the guidance in RG 1.190. Fluence calculations are acceptable if they are performed in accordance with approved methodologies or with methodologies which are shown to conform to the guidance in RG 1.190. Reactor coolant system P-T limit requirements, are specified in Appendix G to Title 10 of the Code of Federal Regulations Part 50, Fracture Toughness Requirements.

3.0 TECHNICAL EVALUATION

3.1 FERRET Code Methodology The proposed amendment would revise TS 5.6.5.b for both PBNP units to add the FERRET methodology (Ref. 6) to the PTLR approved methodologies for the calculation of the vessel fast neutron (E > 1.0 MeV) fluence. The FERRET Code was submitted for staff review in the Westinghouse topical report WCAP-16083-NP. The FERRET Code describes a least squares dosimetry optimization method for use in pressurized-water reactors (PWR) vessel dosimetry measurements. The Code was benchmarked and staff review found it acceptable for referencing in PWR vessels dosimetry calculations. The FERRET Code was approved by the NRC staff on January 10, 2006 (Ref. 3). One of the acceptance criteria was that the transport and dosimetry calculations follow the guidance in RG 1.190 (Ref. 5). The fluence value used for the estimation of the material properties per Appendix G to 10 CFR Part 50 for both PBNP units is determined in accordance with the guidance in RG 1.190. Therefore, the NRC staff finds that the TS change request to add the FERRET code to TS 5.6.5 as an approved methodology is acceptable.

3.2 Effective Full Power Years Westinghouse performed extensive fluence calculations for PBNP Unit 1 with and without the FERRET Code. Those calculations also accounted for hafnium rods (used in the early part of the PBNP operation for vessel flux reduction) in a variety of configurations and accounted for power uprates. The latest best estimate fluence calculations performed by Westinghouse are documented in LTR-REA-04-64 (Ref. 7) and demonstrate that the best estimate value (using the FERRET code) is 29.5 EFPYs for PBNP Unit 1, and is applicable until June 2008. Because the EFPYs for PBNP Unit 2, were not exceeded, the Unit 2 EFPYs were not further evaluated in this SE.

The results of Westinghouses latest fluence calculations, per the FERRET methodology, coupled with the fact that the P-T limits and the limiting RPV beltline values and material properties for both units remain unchanged, correspondingly demonstrate that the Unit 1 reactor vessel was not outside its safety limits. The vessel was fully capable to perform the required service, i.e., the fluence value used for the estimation of the material properties per Appendix G to 10 CFR Part 50 is conservative and in accordance with the guidance in RG 1.190. This conclusion is supported by the information in the NRC Reactor Vessel Integrity

Database. Based on the forgoing, the NRC staff concludes that the PBNP, Unit 1, P-T limits satisfy the requirements of Appendix G to 10 CFR Part 50 and are acceptable for operation through 29.5 for PBNP Unit 1. The NRC staff has completed its review of the FERRET code and the EFPYs and with the issuance and implementation of this license amendment, PBNP, Unit 1 reactor vessel will be in compliance with TS 5.6.5 and the associated P-T limits.

4.0 STATE CONSULTATION

In accordance with the Commission's regulations, the Wisconsin State official was notified of the proposed issuance of the amendments. The State official had no comments.

5.0 ENVIRONMENTAL CONSIDERATION

These amendments change a requirement with respect to the installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20. The staff has determined that the amendments involve no significant increase in the amounts and no significant change in the types of any effluent that may be released offsite, and that there is no significant increase in individual or cumulative occupational radiation exposure. The Commission has previously published a proposed finding that these amendments involve no significant hazards consideration and there has been no public comment on such finding (72 FR 1780). Accordingly, these amendments meet the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9). Pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the issuance of these amendments.

6.0 CONCLUSION

The Commission has concluded, based on the considerations discussed above, that (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of the amendments will not be inimical to the common defense and security or to the health and safety of the public.
