NextEra Energy Point Beach, LLC (NextEra), (formerly known as FPL Energy Point Beach, LLC), submitted a proposed license amendment request for Commission review and approval pursuant to 10 CFR 50.90 for Point Beach Nuclear Plant (PBNP),

Units Iand 2 (Reference I). The proposed amendment revises the licensing basis to reflect a revision to the spent fuel pool (SFP) criticality analysis methodology. The revised criticality analysis for the SFP storage racks credits burnup, integral fuel burnable absorber (IFBA), Plutonium-241 decay, and soluble boron, where applicable.

NextEra provided a supplemental response (Reference 2) containing additional quantitative information to support the fidelity of key methodology aspects described in Reference (1).

Reference ( I ) submitted the proposed Technical Specifications. The Technical Specification Bases were submitted for NRC staff information. Approval of the proposed Bases was not requested. Reference (3) submitted an Addendum to WCAP-16541-PINP, Revision 2, which contained an analysis that restores the full

0. 5% Ak analytical margin for the proposed storage configurations, addressing any identified non-conservatisms.

Document Control Desk Page 2 The enclosures to this letter add "Point Beach Units Iand 2 Spent Fuel Pool Criticality Safety Analysis - Addendum," WCAP-16541-NP, Revision 2, Addendum I, Westinghouse Electric Company, November 2009," as Reference 2 in proposed Technical Specification 4.0. This addition is also made in the reference section for Technical Specification Bases 3.7.1 1 and 3.7.12. Enclosure 1 contains revised Technical Specification 4.0. Enclosure 2 contains Technical Specification Bases 3.7.1 1 and 3.7.12, for information only. NRC approval is not being requested for the revised Bases.

This letter contains no new commitments and no revisions to existing commitments.

The Plant Operations Review Committee has reviewed the proposed change.

The addition of Reference 2 to Technical Specification 4.0 does not alter the no significant hazards consideration contained in Reference (1) and continues to satisfy the criteria of 10 CFR 51.22 for categorical exclusion from the requirements for an environmental assessment.

In accordance with 10 CFR 50.91, a copy of this proposed amendment with enclosures is being provided to the designated Wisconsin Official.

I declare under penalty of perjury that the foregoing is true and correct.

Fuel Storaae Pool Boron Concentration B 3.7.1 1 BASES SURVEILLANCE SR 3.7.11.1 REQUIREMENTS This SR verifies that the concentration of boron in the fuel storage pool is within the required limit. As long as this SR is met, the analyzed accidents are fully addressed. The 7 day Frequency is appropriate because no major replenishment of pool water is expected to take place over such a short period of time.
