168

UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 RELATED TO AMENDMENT NOS. 219 AND 168 TO RENEWED FACILITY OPERATING LICENSE NOS. DPR-67 AND NPF-16 FLORIDA POWER & LIGHT COMPANY. ET AL.

1.0 INTRODUCTION

ST. LUCIE PLANT. UNIT NOS. 1 AND 2 DOCKET NOS. 50-335 AND 50-389 By letter to the U.S. Nuclear Regulatory Commission (NRC or the Commission) dated May 21, 2013 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML13144A166), as supplemented by letter dated October 4, 2013 (ADAMS Accession No. ML13289A179), Florida Power & Light Company (FPL or the licensee) requested to amend Renewed Operating Licenses DPR-67 and NPF-16 for St. Lucie Plant, Unit Nos. 1 and 2 (St. Lucie).

The proposed change would modify the Technical Specifications (TSs) moderator temperature coefficient (MTC) surveillance requirements (SRs) associated with the implementation of Westinghouse Commercial Atomic Power (WCAP)-16011-P-A, "Startup Test Activity Reduction (STAR) Program" (ADAMS Accession No. ML050660118 for the non-proprietary version) for St. Lucie. The WCAP-16011-P-A is a topical report providing the technical justification to support licensees making changes to post-refueling startup physics test programs that are performed following a core reload.

By letter dated March 31, 2003, the Combustion Engineering (CE) Owners Group submitted to the NRC a proposed topical report WCAP-16011-P (proprietary version) and WCAP-16011-NP (nonproprietary version found at ADAMS Package Accession No. ML030980342). By letter dated January 14, 2005 (ADAMS Accession No. ML050180327), the NRC-approved WCAP-16011-P-A for referencing in licensing applications forCE-designed pressurized-water reactors (PWRs).

The supplement dated October 4, 2013, 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 July 23, 2013 (78 FR 44173).

Enclosure

2.0 REGULATORY EVALUATION

In Title 10 of the Code of Federal Regulations (1 0 CFR) Section 50.36, the Commission established its regulatory requirements related to the content of TSs. Pursuant to 1 0 CFR 50.36, the TSs must include items in five specific categories related to station operation: (1) safety limits, limiting safety system settings, and limiting control settings; (2) limiting conditions for operations (LCOs); (3) SRs; (4) design features; and (5) administrative controls.

The regulations do not specify the particular-requirements to be included in a plant's TSs and do not explicitly prescribe specific post-refueling startup testing. However, the post-refueling startup testing can be traced to the pre-operational testing required to be specified in the Final Safety Analysis Report required by 10 CFR 50.34.

Section 50.36 of 10 CFR specifies SRs relating to test, calibration, or inspection to assure that the necessary quality of systems and components is maintained, that facility operation will be within safety limits, and that the limiting conditions for operation will be met.

Appendix A, "General Design Criteria" (GDC), of 10 CFR Part 50 apply, in that the GDC establish the necessary design, fabrication, construction, testing, and performance requirements for structures, systems, and component important to safety. Part 50 of 10 CFR, Appendix B, "Quality Assurance Criteria for Nuclear Power Plants and Fuel Reprocessing Plants," applies, in that Criterion III"Design Control" requires that "measures shall provide for verifying or checking the adequacy of design, such as by the performance of design reviews, by the use of alternate or simplified calculational methods, or by the performance of a suitable testing program."

Specifically, the MTC is a parameter controlled in the licensees' TSs, including the SRs. As a value in the TSs, the MTC and the applicable SRs are subject to regulatory oversight.

Technical Specifications Task Force (TSTF}-486 changes NUREG-1432, "Standard Technical Specifications [STSs] Combustion Engineering Plants," to generically implement MTC SR changes associated with implementation of WCAP-16011-P-A, "Startup Test Activity Reduction (STAR) Program." WCAP-16011-P-A describes methods to reduce the time required for startup testing. WCAP-16011-P-A proposes methods to eliminate the control element assembly (CEA) worth and isothermal temperature coefficient (lTC) measurements at hot zero power (HZP).

The measured lTC is used to calculate the HZP MTC. WCAP-16011-P-A includes a method to substitute the measured verification of MTC at HZP with an alternate MTC verification consisting of the predicted (calculated) MTC and measured critical boron concentration at HZP. When this alternate MTC verification is utilized, WCAP-16011-P-A adds the requirement for the early in-cycle MTC measurement to verify MTC is not more negative or positive than allowed.

WCAP-16011-P-A adds an lTC measurement at intermediate to hot full power and applicability requirements for core design, fabrication, refueling, startup testing, and CEA lifetime viability requirements. WCAP-16011-P-A methods can only be applied to cores that are well characterized by an existing database. WCAP-16011-P-A is only applicable to the particular plants that participated in its development, as indicated in the document. TSTF-486 provides standardized wording in the CE STSs for plants implementing the WCAP-16011-P-A alternate MTC verification at startup.

3.0 TECHNICAL EVALUATION

3.1 Proposed Changes The licensee's proposed license amendment request (LAR) dated May 21, 2013, would modify MTC SRs associated with the implementation of WCAP-16011-P-A. The licensee proposed to make the following changes to the TSs for St. Lucie:

The proposed change revises the MTC SR 4.1.1.4.1, to indicate the MTC upper limit is specified in LCO 3.1.1.4.

The proposed change revises the MTC SR 4.1.1.4.1, Frequency, to add a requirement to verify MTC is within the upper limit within 7 effective full power days (EFPDs) of reaching 40 EFPDs of core burn up for each fuel cycle and prior to entering Mode 1 after each fuel loading. This verification would only be required if the MTC determined prior to entering Mode 1 is determined using an adjusted, predicted MTC.

The proposed change revises MTC SR 4.1.1.4.2 to indicate the MTC lower limit is specified in the core operating limits report (COLR).

The proposed change revises MTC 4.1.1.4.2, Frequency, to add a requirement to verify MTC is within the lower limit within 7 EFPDs of reaching 2/3 of expected core burnup for each fuel cycle. This SR requires that shutdown must occur prior to exceeding the minimum allowable boron concentration at which MTC is projected to exceed the lower limit and allows repeating SR 4.1.1.4.2 if the MTC is more negative than the lower limit specified in the COLR when extrapolated to the end of cycle.

This LAR revises St. Lucie Units 1 and 2 SRs 4.1.1.4.1 and 4.1.1.4.2, associated with TS 3.1.1.4, "Moderator Temperature Coefficient."

Currently, St. Lucie Units 1 and 2 SR 4.1.1.4.1 states:

The MTC shall be determined to be within its limits by confirmatory measurements.

MTC measured values shall be extrapolated and/or compensated to permit direct comparison with the above 1 limits.

The proposed SR 4.1.1.4.1 states; Verify MTC is within the upper limit specified in LCO 3.1.1.4.

a. Prior to entering MODE 1 after each fuel loading, and
b. Each fuel cycle within 7 effective full power days (EFPD) of reaching 40 EFPD core burnup. **
1. The 'above' limits are specified in LCO 3.1.1.4.
    • Only required to be performed when MTC determined prior to entering MODE 1 is verified using adjusted predicted MTC.

Currently, St. Lucie Unit 1 SR 4.1.1.4.2 states:

The MTC shall be determined at the following frequencies and THERMAL POWER conditions during each fuel cycle:

a. Prior to initial operation above 5% of RATED THERMAL POWER, after each refueling.
b. At any THERMAL POWER, within 7 EFPD after initially reaching a RATED THERMAL POWER equilibrium boron concentration.
c. At any THERMAL POWER, within 7 EFPD after reaching a RATED THERMAL POWER equilibrium boron concentration of 300 ppm.

Currently, St. Lucie Unit 2 SR 4.1.1.4.2 states:

The MTC shall be determined at the following frequencies and THERMAL POWER conditions during each fuel cycle:

a. Prior to initial operation above 5% of RATED THERMAL POWER, after each fuel loading.
b. At any THERMAL POWER, within 7 EFPD after reaching a RATED THERMAL POWER equilibrium boron concentration of 800 ppm.
c.

At any THERMAL POWER, within 7 EFPD after reaching a RATED THERMAL POWER equilibrium boron concentration of 300 ppm.

The proposed St. Lucie Units 1 and 2 SR 4.1.1.4.2 states:

4.1.1.4. 2*** Verify MTC is within the lower limit specified in the COLR.

Each fuel cycle within 7 EFPD of reaching 2/3 of expected core burnup.

      • If MTC is more negative than the lower limit specified in the COLR when extrapolated to the end of cycle, 4.1.1.4.2 may be repeated. Shutdown must occur prior to exceeding the minimum allowable boron concentration at which MTC is projected to exceed the lower limit.

3.2 The NRC Staff Technical Evaluation The NRC approved WCAP-16011-P-A on January 14, 2005, for referencing in LARs for participating CE-designed PWRs to the extent specified and under the limitations delineated in the topical report and the NRC staff's safety evaluation. The safety evaluation defines the conditions and limitations for applicability of the STAR program to a plant-specific application.

The proposed amendment would modify the TS MTC SRs associated with the implementation of WCAP-16011-P-A. The WCAP-16011-P-A describes the technical justification to support licensees making changes to post-refueling startup physics test programs that are performed following a core reload.

The NRC staff reviewed the licensee's proposed LAR dated May 21, 2013, and the licensee's response, dated October 4, 2013, to the staff's request for additional information in conjunction with WCAP-16011-P-A, and TSTF-486, Revision 2, as included in NUREG-1432, Revision 4.0.

The NRC staff determined that an NRC-approved methodology, WCAP-16011-P-A, is applied in the LAR to the extent specified and under the limitations and conditions stated in the topical report and the NRC safety evaluation for WCAP-16011-P-A. The St. Lucie cycle specific MTC values are calculated using approved methodologies specified in TS 6.9.1.11.b. "Core Operating Limits Report (COLR)." The staff concluded that the proposed TS changes regarding MTC surveillance for implementing the STAR program is applicable to St. Lucie.

SR 4.1.1.4.1 is being revised to state the upper MTC limit is specified in LCO 3.1.1.4. Currently, the location of the upper limit is stated in TS LCO 3.1.1.4, and SR 4.1.1.4.1 references this limit by stating the above limits." FPL is replacing this wording with, "specified in LCO 3.1.1.4." This change provides a more accurate representation of where the limits are stated and does not change any technical requirements in the TSs. Therefore, this change is acceptable.

SR 4.1.1.4.1 is also being revised to add a frequency that is required by WCAP-16011-P-A when the alternate MTC verification method is used to verify MTC is within the upper limit during startup testing. This frequency is consistent with WCAP-16011-P-A and NUREG-1432, "Combustion Engineering Standard Technical Specifications." Therefore, this change is acceptable.

SR 4.1.1.4.2 is being revised to state the lower MTC limit is in the COLR. Currently, the location of the lower limit is specified in LCO 3.1.1.4 to be, "in the COLR." This change makes SR 4.1.1.4.2 consistent with the LCO 3.1.1.4. The specific wording is also consistent with current wording in the NUREG-1432. Therefore, this change is acceptable.

The NRC staff also determined that an acceptable justification was provided by the licensee for the deviation of SR 4.1.1.4.2 for the MTC lower limit verification between each fuel cycle within 7 EFPDs of reaching 40 EFPDs core burnup and each fuel cycle within 7 EFPDs of reaching 2/3 of expected core burnup. Within 7 EFPDs of reaching 40 EFPDs of each fuel cycle is early in the cycle and adds less technical value for verification of the MTC lower limit. However, within 7 EFPDs of reaching 2/3 of expected core burnup of each fuel cycle verifies the lower limit well in advance of reaching the expected end of-life core burnup and well in advance of approaching the MTC lower limit. Therefore, the proposed deviation is acceptable.

In summary, the NRC staff concludes that the proposed changes are consistent with TSTF-486, Revision 2, NUREG-1432, Revision 4.0 and WCAP-16011-P-A, therefore the proposed TS changes to St. Lucie Units 1 and 2 SR 4.1.1.4.1 and SR 4.1.1.4.2 are acceptable.

3.3 Technical Evaluation Conclusion

The Commission has concluded, on the basis of 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.

4.0 STATE CONSULTATION

Based upon a letter dated May 2, 2003, from Michael N. Stephens of the Florida Department of Health, Bureau of Radiation Control, to Ms. Brenda L. Mozafari, Senior Project Manager, U.S. Nuclear Regulatory Commission, the State of Florida does not desire notification of issuance of license amendments. In an email dated July 25, 2012 (ADAMS Accession No. ML12208A014), from Cynthia Becker, Florida State Bureau of Radiation Control, to Farideh Saba, Senior Project Manager, U.S. Nuclear Regulatory Commission, the State of Florida confirmed that the May 2003 letter continues to reflect the State's position on notification of issuance of license amendments.

5.0 ENVIRONMENTAL CONSIDERATION

These amendments change a requirement with respect to installation or use of a facility component located within the restricted area as defined in 1 0 CFR Part 20 and changes surveillance requirements. The NRC staff has determined that the amendment involves no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite, and that there is no significant increase in individual or cumulative occupational radiation exposure. The Commission has previously issued a proposed finding that the amendment involves no significant hazards consideration and there has been no public comment on such finding (78 FR 44173, dated July 23, 2013). 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) there is reasonable assurance that such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.
