By letter L-2010-113 dated October 21, 2010 [Reference 1], Florida Power and Light Company (FPL) requested to amend the Renewed Facility Operating Licenses DPR-31 and DPR-41 and revise the Turkey Point Units 3 and 4 Technical Specifications (TS) to implement an Extended Power Uprate (EPU) for each unit of approximately 15% that includes a 13% power uprate and a 1.7% measurement uncertainty recapture (MUR). The proposed amendments will increase each unit's licensed core power level from 2300 megawatts thermal (MWt) to 2644 MWt and revise C
tý0,
Turkey Point Nuclear Plant L-2011-390 Docket Nos. 50-250 and 50-251 Page 2 of 3 the Renewed Facility Operating Licenses and Technical Specifications to support operation at this increased core thermal power level.
By letter L-2010-169 dated August 5, 2010 [Reference 2], FPL requested to amend the Renewed Facility Operating Licenses DPR-31 and DPR-41 and revise the Turkey Point Units 3 and 4 TS 5.5.1 Fuel Storage - Criticality, to include new spent fuel storage patterns that account for both the increase in fuel maximum enrichment from 4.5 wt% U-235 to 5.0 wt% U-235 and the impact on the fuel of higher power operation proposed under the EPU project. Although the fuel storage was analyzed at the higher fuel enrichment in a new criticality analysis, the fuel enrichment limit of 4.5 wt% U-235 specified in TS 5.5.1 was not changed under the license amendment request (LAR No. 207). WCAP- 17094-P, Rev 2, "Turkey Point Units 3 and 4 New Fuel Storage Rack and Spent Fuel Pool Criticality Analysis," dated July 2010 was provided in Reference 2.
By letter L-2011-032 dated February 22, 2011 [Reference 3], FPL supplemented LAR No. 207 Fuel Storage Criticality Analysis, dated August 5, 2010 [Reference 2] with new proposed TS changes and supporting criticality analysis (WCAP-17094-P, Rev 3, "Turkey Point Units 3 and 4 New Fuel Storage Rack and Spent Fuel Pool Criticality Analysis," dated February 2011).
By letters L-2011-386 and L-2011-401 dated September 14 and 22, 2011 [References 4 and 5, respectively], FPL again supplemented LAR No. 207 to address specific NRC questions.
On October 31, 2011, the U.S. Nuclear Regulatory Commission (NRC) approved LAR No. 207 with the issuance of Amendments 246 and 242 for Turkey Point Units 3 and 4 addressing both new and spent fuel storage requirements [Reference 6].
As indicated in EPU LAR No. 205, the LAR No. 207 basis and justification for its TS changes included the impact of the higher enrichment and operation under EPU conditions so that it applies to and supports the proposed EPU TS changes. As such, the EPU proposed TS changes to TS 5.5.1 submitted in Reference 1 have been superseded by the newly issued amendments except for the proposed changes to TS 5.5.1.1.d and TS 5.5.1.2.b which will increase the maximum allowable enrichment in the spent fuel storage racks and the new fuel storage area to 5.0 wt% U-235.
Additionally, the proposed change to TS 5.5.1.2.b requires that storage of fuel assemblies in the new fuel storage area with nominal enrichments greater than 4.5 wt% U-235 have 16 or more Integral Fuel Burnable Absorber (IFBA) rods or an equivalent amount of other burnable absorber. Therefore, the previously proposed EPU changes regarding new and spent fuel storage will be superseded by the above changes to TS 5.5.1.1.d and 5.5.1.2.b. In addition, a change to the Power Range High Neutron Flux Allowable Value and Trip setpoint in TS Table 2.2-1 is being resubmitted here to correct a clerical error in the TS markup supplied via FPL letter L-2011-302 dated August 29, 2011
[Reference 7]. The TS Table 2.2-1 change was correctly submitted earlier in FPL letter L-2011-190 dated June 21, 2011 [Reference 8].
The Attachment to this letter contains a description of the proposed changes and their supporting justifications. As both the proprietary and non-proprietary versions of WCAP-17094, Rev 3, Turkey Point Units 3 and 4 New Fuel Storage Rack and Spent Fuel Pool Criticality Analysis, dated February 2011 were docketed as part of the LAR 207 supplement [Reference 3], they are not provided again as part of this submittal.

Turkey Point Nuclear Plant L-2011-390 Docket Nos. 50-250 and 50-251 Attachment Page 2 of 7 Supplement 2 to the Extended Power Uprate License Amendment Request No. 205 Regarding New and Spent Fuel Storage Requirement By letter L-2010-113 dated October 21, 2010 [Reference 1], Florida Power and Light Company (FPL) requested to amend the Renewed Facility Operating Licenses DPR-31 and DPR-41 and revise the Turkey Point Units 3 and 4 Technical Specifications (TS) to implement an Extended Power Uprate (EPU) for each unit of approximately 15% that includes a 13% power uprate and a 1,7% measurement uncertainty recapture (MUR). The proposed amendments will increase each unit's licensed core power level from 2300 megawatts thermal (MWt) to 2644 MWt and revise the Renewed Facility Operating Licenses and Technical Specifications to support operation at this increased core thermal power level.
By letter L-2010-169 dated August 5, 2010 [Reference 2], FPL requested to amend the Renewed Facility Operating Licenses DPR-31 and DPR-41 and revise the Turkey Point Units 3 and 4 TS 5.5.1 Fuel Storage - Criticality, to include new spent fuel storage patterns that account for both the increase in fuel maximum enrichment from 4.5 wt% U-235 to 5.0 wt% U-235 and the impact on the fuel of higher power operation proposed under the EPU project. Although the fuel storage was analyzed at the higher fuel enrichment in a new criticality analysis, the fuel enrichment limit of 4.5 wt% U-235 specified in TS 5.5.1 was not changed under the license amendment request (LAR No. 207). WCAP-17094-P, Rev 2, "Turkey Point Units 3 and 4 New Fuel Storage Rack and Spent Fuel Pool Criticality Analysis," dated July 2010 was provided in Reference 2.
By letter L-2011-032 dated February 22, 2011 [Reference 3], FPL supplemented LAR No. 207 Fuel Storage Criticality Analysis, dated August 5, 2010 [Reference 2] with new proposed TS changes and supporting criticality analysis (WCAP-17094-P, Rev 3, "Turkey Point Units 3 and 4 New Fuel Storage Rack and Spent Fuel Pool Criticality Analysis," dated February 2011).
By letters L-2011-386 and L-2011-401 dated September 14 and 22, 2011 [References 4 and 5, respectively], FPL again supplemented LAR No. 207 to address specific NRC questions.
On October 31, 2011, the U.S. Nuclear Regulatory Commission (NRC) approved LAR No. 207 with the issuance of Amendments 246 and 242 for Turkey Point Units 3 and 4 addressing both new and spent fuel storage requirements [Reference 6].
As indicated in EPU LAR No. 205, the LAR No. 207 basis and justification for its TS changes included the impact of the higher enrichment and operation under EPU conditions so that it applies to and supports the proposed EPU TS changes. As such, the EPU proposed TS changes to TS 5.5.1 submitted in Reference 1 have been superseded by the newly issued amendments except for the proposed changes to TS 5.5.1.1.d and TS 5.5.1.2.b which will increase the maximum allowable enrichment in the spent fuel storage racks and the new fuel storage area to 5.0 wt% U-235.
Additionally, the proposed change to TS 5.5.1.2.b requires that storage of fuel assemblies in the new fuel storage area with nominal enrichments greater than 4.5 wt% U-235 have 16 or more Integral Fuel Burnable Absorber (IFBA) rods or an equivalent amount of other burnable absorber. Therefore, the previously proposed EPU changes regarding new and spent fuel storage will be superseded by the above changes to TS 5.5.1.1 .d and 5.5.1.2.b. In addition, a change to the Power Range High Neutron Flux Allowable Value and Trip setpoint in TS Table 2.2-1 is being resubmitted here to correct a clerical error in the TS markup supplied via FPL letter L-2011-302 dated August 29, 2011

Turkey Point Nuclear Plant L-2011-390 Docket Nos. 50-250 and 50-251 Attachment Page 3 of 7 As both the proprietary and non-proprietary versions of WCAP- 17094, Rev 3, Turkey Point Units 3 and 4 New Fuel Storage Rack and Spent Fuel Pool Criticality Analysis, dated February 2011 were docketed as part of the LAR No. 207 supplement [Reference 3], they are not presented here. A description of the proposed TS changes and their supporting justifications is provided below.
Changes to the PTN Operating Licenses and Technical Specifications Technical Specification 5.5.1 Fuel Storage - Criticality Approved TS (Amendments 246 and 242) 5.5.1.1 The spent fuel storage racks are designed and shall be maintained with:
- d. A maximum enrichment loading for fuel assemblies of 4.5 weight percent ofU-235.
5.5.1.2 The racks for new fuel storage are designed to store fuel in a safe subcritical array and shall be maintained with:
- b. Fuel assemblies placed in the New Fuel Storage Area shall contain no more than 4.5 weight percent of U-235.
Proposed TS 5.5.1.1 The spent fuel storage racks are designed and shall be maintained with:
- d. A maximum enrichment loading for fuel assemblies of 5.0 weight percent of U-235.
5.5.1.2 The racks for new fuel storage are designed to store fuel in a safe subcritical array and shall be maintained with:
- b. Fuel assemblies placed in the New Fuel Storage Area shall contain no more than a nominal 4.5 weight percent of U-235 if the assembly contains no burnable absorber rods and no more than 5.0 weight percent of U-235 if the assembly contains at least 16 IFBA rods (or an equivalent amount of other burnable absorber).
TS changes previously proposed under EPU LAR 205 [Reference 1] affecting TS 5.5.1.1 b, 5.5.1. lc, 5.5.1.1f, 5.5.1.3, Tables 5.5-1 through 5.5-3, and Figures 5.5-1 through 5.5-4 have been superseded by Amendments 246 and 242 and so are withdrawn. Only the TS changes indicated above remain.
Basis for the Change:
As stated in EPU LAR No. 205 Attachment 1 [Reference 1], LAR No. 207 [Reference 2] submitted proposed TS changes and a new criticality analysis (WCAP-17094-P, Rev 2, "Turkey Point Units 3 and 4 New Fuel Storage Rack and Spent Fuel Pool Criticality Analysis," dated July 2010) to revise the current licensing basis for both new fuel and spent fuel storage. The LAR 207 TS changes were based on analysis that accounted for both the increase in fuel maximum enrichment from 4.5 wt%
U-235 to 5.0 wt% U-235 and the impact on the fuel of higher power operation proposed under EPU conditions, but did not request a change to the fuel maximum enrichment limit. These TS changes to the fuel maximum enrichment limit were reflected in the EPU LAR [Reference 1].
A supplement to LAR No. 207 [Reference 3] revised the proposed TS changes based on a further revised criticality analysis (WCAP- 17094-P, Rev 3, "Turkey Point Units 3 and 4 New Fuel Storage Rack and Spent Fuel Pool Criticality Analysis," dated February 2011). The proposed TS changes and latest criticality analysis were approved by the NRC with the issuance of Amendments 246 and 242 on October 31, 2011 [Reference 6]. It did not, however, propose that the fuel enrichment limit
Turkey Point Nuclear Plant L-2011-390 Docket Nos. 50-250 and 50-251 Attachment Page 4 of 7 of 4.5 wt% U-235 be changed. In the EPU LAR, the proposed TS changes are identical. except that the changes to TS 5.5.1.1 .d and TS 5.5.1.2.b will increase the maximum allowable enrichment in the spent fuel storage racks and the new fuel storage area to 5.0 wt% U-235. Additionally, the proposed change to TS 5.5.1.2.b requires that storage of fuel assemblies in the new fuel storage area with nominal enrichments greater than 4.5 wt% U-235 have 16 or more IFBA rods or an equivalent amount of other burnable absorber based on the latest criticality analysis. Since the LAR No. 207 basis and justification for its proposed TS changes included the impact of the higher enrichment and operation under EPU conditions, it also applies to and supports the proposed EPU TS changes regarding fuel storage requirements.
See attached TS 5.5.1.1.d and TS 5.5.1.2.b (TS page 5-5) markup. Note Functional Unit 10, 11 and loop design flow are associated with changes previously submitted in Reference 1 and are not changed by this submittal.
