1.0 INTRODUCTION

By letter dated July 8, 2014, as supplemented by letter dated July 15, 2015, 1 Florida Power & Light Company (the licensee) requested changes to the Technical Specifications (TSs) for Turkey Point Nuclear Generating Unit Nos. 3 and 4 (Turkey Point 3 and 4), which are contained in Appendix A of Renewed Facility Operating License Nos. DPR-31 and DPR-41.

The licensee requested to revise or add surveillance requirements (SRs) to the TSs to verify that system locations susceptible to gas accumulation are sufficiently filled with water and to provide allowances that permit performance of the verification. The licensee requested to adopt the U.S. Nuclear Regulatory Commission (NRC)-approved Technical Specifications Task Force (TSTF) Standard Technical Specifications (STSs) Change Traveler TSTF-523, Revision 2, "Generic Letter [GL] 2008-01, Managing Gas Accumulation," dated February 21, 2013. 2 The Federal Register (FR) notice published on January 15, 2014 (79 FR 2700), announced the availability of this TSTF.

The supplemental letter dated July 15, 2015, did not expand the scope of the application as originally noticed and did not change the NRC staff's original proposed no significant hazards consideration determination, as published in the FR on October 14, 2014 (79 FR 61661).

2.0 REGULATORY EVALUATION

2.1 Background On January 11, 2008, the NRC issued GL 2008-01, "Managing Gas Accumulation in Emergency Core Cooling, Decay Heat Removal, and Containment Spray Systems," 3 to address the issue of gas accumulation in emergency core cooling systems (ECCSs), decay heat removal (OHR) systems, and containment spray (CS) systems. Gas accumulation in such systems can result in water hammer, pump cavitation, and pumping of noncondensible gas into the reactor vessel.

These effects may result in the subject system being unable to perform its specified safety function. The industry and NRC staff agreed that a change to the STSs and plant-specific TSs would be necessary to address some issues discussed in GL 2008-01. TSTF-523, Revision 2 contains proposed changes to the STSs SRs and Bases to address some of the concerns in GL 2008-01.

2.2 Description of Proposed Changes The licensee proposed revising the Turkey Point 3 and 4 TSs to adopt the changes described in TSTF-523, Revision 2, with variations to address plant-specific numbering, format, and titles in the Turkey Point TSs. The proposed changes would revise ECCS SRs related to gas accumulation and add new SRs related to gas accumulation for the residual heat removal (RHR) and CS systems. The licensee also included associated draft changes to its TS Bases in its application.

The licensee proposed the following changes to the TSs (Section 3 of this Safety Evaluation describes the changes in more detail):

SR 4.4.1.4.1.3;

renumber SR 4.4.1.4.2 to SR 4.4.1.4.2.1 and add new SR 4.4.1.4.2.2;

Greater than or Equal to 350 °F [degrees Fahrenheit)": revise SRs 4.5.2b.1 and 4.5.2b.2;

  • TS 3/4.6.2, "Containment Systems - Depressurization and Cooling Systems": revise SR 4.6.2.1 a, add new SR 4.6.2.1 c, and renumber the remaining SRs;

renumber SR 4.9.8.2 to 4.9.8.2.1 and add new SR 4.9.8.2.2.

2.3 Regulatory Review The NRC staff considered the following regulatory requirements, guidance, and plant-specific licensing and design basis information during its review of the licensee's application.

TSTF 523, Revision 2 and its associated model safety evaluation 4 discuss applicable regulatory requirements and guidance, including 10 CFR Part 50, Appendix A. However, the Turkey Point 3 and 4 design approval for the construction phase was based on the proposed general design criteria (GDC) published by the Atomic Energy Commission in the FR (32 FR 10213) on July 11, 1967. Section 1.3, "General Design Criteria," .of the Turkey Point 3 and 4 Updated Final Safety Analysis Report (UFSAR) describes the Turkey Point GDC'. The UFSAR evaluation of the following draft GDC reflect design requirements similar to those specified in the final GDC discussed in TSTF-523, Revision 2: Criterion 1, "Quality Standards," Criterion 37, "Engineered Safety Features Basis for Design," Criterion 44, "Emergency Core Cooling Systems Capability,"

Criterion 45, "Inspection of Emergency Core Cooling Systems," Criterion 46, "Testing of Emergency Core Cooling Systems Components," Criterion 47, "Testing of Emergency Core Cooling Systems," Criterion 48, "Testing of Operational Sequence of Emergency Core Cooling Systems," Criterion 52, "Containment Heat Removal Systems," Criterion 58, "Inspection of Containment Pressure-Reducing Systems," Criterion 59, "Testing of Containment Pressure-Reducing Systems," Criterion 60, "Testing of Containment Spray Systems," and Criterion 61, "Testing of Operational Sequence of Containment Pressure-Reducing Systems." Additionally, the regulations in 1O CFR 50.46 provide specified ECCS performance criteria.

Appendix B, "Quality Assurance Criteria for Nuclear Power Plants and Fuel Reprocessing Plants," to Part 50 requires that applicants for construction permits include in their preliminary safety analysis reports a description of the quality assurance program to be applied to the design, fabrication, construction, and testing of the structures, systems, and components of the facility. Part 50, Appendix B also requires that applicants for operating licenses include, in their final safety analysis reports, information pertaining to the managerial and administrative controls to be used to assure safe operation. The quality assurance criteria provided in Part 50, Appendix B that apply to gas management in the subject systems include: Criteria Ill, V, XI, XVI, and XVII. Criteria Ill and V require measures to ensure that applicable regulatory requirements and the design basis, as defined in 10 CFR 50.2, "Definitions," and as specified in the license application, are correctly translated into controlled specifications, drawings, procedures, and instructions. Criterion XI requires a test program to ensure that the subject systems will perform satisfactorily in service and requires that test results shall be documented and evaluated to ensure that test requirements have been satisfied. Criterion XVI requires measures to ensure that conditions adverse to quality, such as failures, malfunctions, deficiencies, deviations, defective material and equipment, and nonconformances, are promptly identified and corrected, and that significant conditions adverse to quality are documented and reported to management. Criterion XVII requires maintenance of records of activities affecting quality.

The NRC's regulatory requirements related to the content of the TSs are contained in 10 CFR 50.36(c). The regulations in 10 CFR 50.36 require that the TSs include items in the 4 ADAMS Accession No. ML13255A169.

following categories: (1) safety limits, limiting safety systems settings, and limiting control settings; (2) limiting conditions for operation (LCOs); (3) SRs; (4) design features; and (5) administrative controls. SRs are requirements 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 LCOs will be met. Section 6 of the Turkey Point TSs requires the licensee to establish, implement, and maintain written procedures

.covering the applicable procedures recommended in Appendix A to Regulatory Guide (RG) 1.33, "Quality Assurance Program Requirements (Operation)." Furthermore, Appendix A to RG 1.33 identifies instructions for filling and venting the ECCS and OHR system, as well as for draining and refilling heat exchangers.

3.0 TECHNICAL EVALUATION

The SRs the licensee proposed to add are consistent with TSTF-523, Revision 2, and are appropriate to address the issues discussed in GL 2008-01. The NRC staff compared the proposed changes to the existing SRs, as well as the regulatory requirements of 10 CFR 50.36(c). The proposed SRs must be sufficient to provide reasonable assurance that the necessary quality of systems and components are maintained, that facility operation will be within safety limits, and that the limiting conditions for operation will be met.

The licensee proposed the following TS changes:

(1) Add SR 4.4.1.3.4, which states, "Verify required RHR loop locations susceptible to gas accumulation are sufficiently filled with water in accordance with the Surveillance Frequency Control Program.*" The added Footnote (*) states, "Not required to be performed until 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> after entering MODE 4."

(2) Add SR 4.4.1.4.1.3, which states, "Verify required RHR loop locations

(3) Renumber SR 4.4.1.4.2 to SR 4.4.1.4.2.1, and add SR 4.4.1.4.2.2, which states, "Verify RHR loop locations susceptible to gas accumulation are sufficiently filled with water in accordance with the Surveillance Frequency Control Program."

(4) Revise the language for SR 4.5.2b.1, which currently states, "Verifying that the ECCS piping is full of water by venting the ECCS pump casings and accessible discharge piping, and[,]" to state, "Verifying ECCS locations susceptible to gas accumulation are sufficiently filled with water, and[.]"

(5) Add Footnote (**) to SR 4.5.2b.2, which states, "Not required to be met for system vent flow paths opened under administrative control."

(6) Add Footnote (*) to SR 4.6.2.1 a, which states, "Not required to be met for system vent flow paths opened under administrative control."

(7) Renumber current SRs 4.6.2.1 c and 4.6.2.1 d to SRs 4.6.2.1 d and 4.6.2.1 e, respectively and add a new SR 4.6.2.1 c, which states, "In accordance with the

Surveillance Frequency Control Program by verifying containment spray locations susceptible to gas accumulation are sufficiently filled with water."

(8) Add SR 4.9.8.1.3, which states, "Verify required RHR loop locations susceptible to gas accumulation are sufficiently filled with water in accordance with the Surveillance Frequency Control Program."

(9) Renumber SR 4.9:8.2 to SR 4.9.8.2.1, and add SR 4.9.8.2.2, which states, "Verify RHR loop locations susceptible to gas accumulation are sufficiently filled with water in accordance with the Surveillance Frequency Control Program.

(10) Add and revise the affected TS SR Bases language to state the purpose of the SRs, discuss methods of identifying locations susceptible to gas accumulation, discuss gas volume acceptance criteria, discuss methods for performing the SR consistent with licensee actions and ongoing programs related to GL 2008-01, and describe the SR frequency.

(11) Add and revise TS LCO Bases language to describe what is required for operability of the systems and to reiterate the importance of gas management.

The new language for the SRs was developed using licensee responses to GL 2008-01. and the NRC discussion contained in Task Interface Agreement (TIA) 2008-03, "Emergency Core Cooling System (ECCS) Voiding Relative to Compliance with Surveillance Requirements (SR) 3.5.1.1, 3.5.2.3, and 3.5.3.1." 5 Many of the GL 2008-01 responses stated that licensees identified system locations susceptible to gas accumulation. In the TIA, the NRC stated that the intent of the TS SRs, which state "full of water," may be met if the licensee can establish, through an Operability Determination, that there is a reasonable expectation that the system in question will perform its specified safety function. Therefore, the phrase, "sufficiently filled with water," was recommended for the proposed TS changes. In the TSs, "sufficiently filled with water" is understood to mean, "sufficiently filled with water to support Operability."

The regulations in 10 CFR 50.36(c)(3) state that one of the purposes of the SR is to verify that the LCO is met. Therefore, the NRC staff finds that the new SR language that states, "Verify the [system name] locations susceptible to gas accumulation are sufficiently filled with water," is acceptable because this language will allow the licensee to make a conclusion as to whether or not a system is operable.

The language for the notes that state that the SR does not have to be performed until 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> after entering Mode 4 is acceptable because the note provides a limited time to perform the.

Surveillance. after entering the Applicability of the LCO. The licensee must have confidence that the SR can be met, or else the licensee must declare the LCO not met.

The language for the notes that allow the SRs to not be met for system vent flow paths opened under administrative control is necessary to allow the licensee to credit administratively controlled manual action to close the system vent flow path in order to maintain system 5 ADAMS Accession No. ML082560209.

Operability during system venting and performance of the proposed gas accumulation SR Therefore, the NRC finds that these notes are acceptable.

The NRC staff found that the proposed SRs meet the regulatory requirements of 10 CFR 50.36 because they provide assurance that the necessary quality of systems and components will be maintained and that the LCOs will be met. Therefore, the NRC staff finds the proposed change acceptable.

4.0 STATE CONSULTATION

In accordance with the Commission's regulations, the NRC staff notified the State of Florida official (Ms. Cynthia Becker, M.P.H., Chief of the Bureau of Radiation Control, Florida Department of Health) on July 16, 2015, 6 of the proposed issuance of the amendments. The State official had no comments.

5.0 ENVIRONMENTAL CONSIDERATION

The amendments change a requirement with respect to the installation or use of facility components located within the restricted area as defined in 10 CFR Part 20 and changes SRs.

The NRC staff has determined that the amendments involve 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 previously issued a proposed finding that the amendments involve no significant hazards consideration, and there has been no public comment on the proposed finding published in the FR on October 14, 2014 (79 FR 61661). Accordingly, the 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 the 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 amendments will not be inimical to the common defense and security or to the health and safety of the public.
