By letter L-2010-169 dated August 5, 2010 [Reference 1], Florida Power and Light Company (FPL) requested to amend Renewed Facility Operating Licenses DPR-31 and DPR-41 and revise the Turkey Point Units 3 and 4 Technical Specifications (TS). The proposed amendment will revise TS 5.5.1, Fuel Storage - Criticality, to include new spent fuel storage patterns that account for both the increased maximum fuel enrichment from 4.5 wt% U-235 to 5.0 wt% U-235 and the impact of higher power operation proposed under the Extended Power Uprate (EPU) project.

Although nuclear fuel storage has been analyzed at the increased fuel enrichment in the new criticality analysis, the enrichment limit of 4.5 wt% U-235 specified in TS 5.5.1 will not be changed under this license amendment request (LAR).

On February 22, 2011, FPL supplemented LAR No. 207 by letter L-2011-032 [Reference 2] to provide a revised fuel storage criticality analysis and updated revisions to TS 5.5.1 to address the NRC Interim Staff Guidance (ISG) contained in DSS-ISG-2010-01 [Reference 3].

Turkey Point Units 3 and 4 L-2011-401 Docket Nos. 50-250 and 50-251 Page 2 of 2 On April 28, 2011, FPL received a Request for Additional Information (RAI) via email [Reference 4]

from the NRC Project Manager (PM) regarding the fuel storage criticality analysis associated with LAR No. 207. FPL responded to the RAI questions by letter L-2011-154, dated May 20, 2011

[Reference 5].

On September 1, 2011, during a teleconference between FPL and NRC staff, the NRC requested an additional change in TS 5.5.1.1 f to clarify the allowable fuel storage configurations. On September 14, 2011, FPL provided the requested clarification via letter L-2011-386 [Reference 6].

On September 13, 2011, during another teleconference between FPL and NRC staff, the NRC PM indicated that a NRC technical reviewer had requested another change to the Fuel Storage TS to include Areal Density Criteria for the Metamic Inserts. The criteria will be added as TS 5.5.1.1 g.

FPL's response to this NRC request is provided in the Attachment to this letter.

This submittal does not alter the significant hazards consideration or the environmental assessment previously submitted by FPL letter L-2011-032 [Reference 2].

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

The Turkey Point Plant Nuclear Safety Committee (PNSC) has reviewed the proposed license amendment. In accordance with 10 CFR 50.91(b)(1), a copy of this letter is being forwarded to the State Designee of Florida.

Should you have any questions regarding this submittal, please contact Mr. Robert J. Tomonto, Licensing Manager, at (305) 246-7327.

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

Executed on September ,2 ,Z-, 2011.

On February 22, 2011, FPL supplemented LAR No. 207 by letter L-2011-032 [Reference 2] to provide a revised fuel storage criticality analysis and updated revisions to TS 5.5.1 to incorporate the NRC Interim Staff Guidance (ISG) contained in DSS-ISG-2010-01 [Reference 3].

On September 1, 2011, during a teleconference between FPL and NRC staff, the NRC requested an additional change in TS 5.5.1.1 f to clarify the allowable fuel storage configurations. On September 14, 2011, FPL provided the requested clarification via letter L-2011-386 [Reference 4].

On September 13, 2011, during another teleconference between FPL and NRC staff, the NRC Project Manager indicated that a NRC technical reviewer had requested another change to the Fuel Storage TS to include Areal Density Criteria for the Metamic Inserts. The requested criteria will be included as TS 5.5.1.1 g. The requested revision to the affected page (TS Page 5-5) and the associated description and justification are presented below.

This submittal only affects the addition of TS 5.5.1.1g. The revisions shown to TS 5.5.1.1b, TS 5.5.1.1c, and TS 5.5.1.1f are retained from References 2 and 4.

TS Changes Technical Specification 5.5.1.1, Fuel Storage - Criticality Current TS 5.5.1.1 The spent fuel storage racks are designed and shall be maintained with:

Proposed TS 5.5.1.1 The spent fuel storage racks are designed and shall be maintained with:

a through f.

g. The Metamic neutron absorber inserts shall have a minimum certified l0 B areal density greater than or equal to 0.015 grams l°B/cm 2.

Basis for the Change: TS 5.5.1.1 g is added to specify the minimum certified l0B areal density for the Metamic neutron absorber inserts consistent with the spent fuel pool criticality analysis provided in Supplement I to LAR 207, i.e., WCAP-17094-P, Turkey Point Units 3 and 4 New Fuel Storage Rack and Spent Fuel Pool Criticality Analysis, Revision 3 [Reference 2].
