CONTENTS OF THE TURKEY POINT NUCLEAR GENERATING STATION IMPROVED TECHNICAL SPECIFICATIONS (ITS) SUBMITTAL Executive Summary The proposed changes from the Turkey Point Nuclear Generating Station (PTN) Unit 3 and Unit 4 current Technical Specifications (CTS) to the Improved Standard Technical Specifications (ISTS) are based on Revision 5.0 of NUREG 1431, Standard Technical Specifications - Westinghouse Plants. There are no additional NRC approved generic changes (Technical Specification Task Force (TSTF) change travelers) since approval of NUREG-1431, Revision 5, to address in this license amendment request as of September 15, 2021. Additionally, there are no linked PTN submittals associated with this ITS license amendment request. Technical Specification Task Force (TSTF)-GG-13-01, Improved Technical Specifications Conversion Guidance, Revision 0, was used to prepare the content of the license amendment request.
* The Battery Monitoring and Maintenance Program is included to provide for battery restoration and maintenance per the guidance of IEEE 450-2010, IEEE Recommended Practice for Maintenance, Testing, and Replacement of Vented Lead-Acid Batteries for Stationary Applications. The Notice of Availability for TSTF-500, Revision 2, "DC Electrical Rewrite - Update to TSTF-360," (76FR54510) references the model application and safety evaluation for plant-specific adoption of TSTF-500, Revision 2 (NRC ADAMS Accession No. ML111751792). PTN has verified the applicable information specified in Section 2.2 of the TSTF-500 model application, including applicable UFSAR information. FPL has verified the following information in support of PTN adoption of TSTF-500, Revision 2:
* A letter has been obtained from the manufacturer of the batteries used at PTN Units 3 and 4 verifying the acceptability of using float current monitoring instead of specific gravity monitoring as a reliable and accurate indication of the state-of-charge of the battery and that this will hold true over the life of the battery.
* Measurement equipment used to monitor float current has the necessary accuracy and capability to measure electrical currents in the expected range.
* Spare battery chargers are available and appropriately sized to support each battery. Each 125 VDC battery charger is a full capacity charger. Typically, two battery chargers are operated in parallel to supply the battery and carry the DC loads. However, either connected battery charger can meet full DC bus load demand and recharge its associated battery. In addition, an additional full capacity swing battery charger can be connected to either DC bus.
* Maintaining battery connection resistances below the battery manufacturer specifications keeps the battery bounded by the battery performance data that was used to qualify the cells. The connection resistance readings are maintained within E1-1

20% of the baseline resistance values determined during installation for optimum performance of the battery system. IEEE 450-2010 supports this methodology.
Proposed commitments associated with TSTF-500 are provided in Enclosure 5. A description of the proposed UFSAR changes associated with TSTF-500 are provided in . Proposed commitments and UFSAR revision packages associated with TSTF-500 will be completed prior to implementation of the ITS Amendment.
Several risk informed initiatives incorporated into the Improved Standard Technical Specifications (ISTS) and associated Bases specified in NUREG-1431, Rev. 5.0, have been previously approved and incorporated into the PTN Unit 3 and Unit 4 Technical Specifications. Therefore, information related to the NRC reviewer notes provided in the ISTS and ISTS Bases associated with these risk informed initiatives are provided in the LAR submittals, FPL responses to NRC staff requests for additional information, and accompanying safety evaluations associated with these risk informed license amendments.
PTN adopted a Surveillance Frequency Control Program (SFCP) on Ju1y 16, 2015, in License Amendments 263 and 258, for Unit 3 and Unit 4 respectively (NRC ADAMS Accession No. ML15166A320). In the NRC safety evaluation accompanying the SFCP amendments, the NRC concluded that the adoption of TSTF-425, Revision 3, and risk-informed methodology of NEI 04-10, "Risk-Informed Method for Control of Surveillance Frequencies," Revision 1, as referenced in the Administrative Controls section of the Technical Specifications, satisfies the key principles of risk-informed decisionmaking applied to the relocated Surveillance frequencies as delineated in Regulatory Guide 1.177, Revision 1, and Regulatory Guide 1.174, Revision 2. Changes to Surveillance frequencies listed in the SFCP are made in accordance with NEI 04-10, Revision 1, as specified in CTS Chapter 6 (ITS Chapter 5).
PTN adopted TSTF -505, Revision 1, "Provide Risk-Informed Extended Completion Times - RITSTF Initiative 4b" to include Risk Informed Completion Times (RICTs) for selected Technical Specification systems. License Amendments 284 and 278, were issued on December 3, 2018, for Unit 3 and Unit 4 respectively, to incorporate the RICTs and an associated administrative program (NRC ADAMS Accession No. ML182703A429). In the NRC safety evaluation accompanying the RICT amendment, the NRC found that the PTN PRA maintenance and change process ensures that the configuration risk management program models used in the RICT calculations will continue to use PRA methods acceptable to the NRC and that the PRA model will be updated as necessary to reflect the as-built and as-operated plant. The NRC also found that appropriate programmatic and procedural controls for the RICT Program are consistent with the guidance of NEI 06-09, Revision 0-A. Controls to calculate Risk Informed Completion Times (RICTs) are provided in the CTS Chapter 6 (ITS Chapter 5) and implemented in accordance with NEI 06-09-A, Revision 0, "Risk-Managed Technical Specifications (RMTS) Guidelines. The LAR submittal, FPL responses to NRC staff requests for additional information, and safety evaluation accompanying the RICT amendment address the implementation of the RICT program to perform a contemporaneous assessment of the overall impact on safety of proposed plant configurations prior to performing and during performance of maintenance activities that remove equipment from service as stated in several NRC reviewer notes in the ISTS Bases.
E1-2 of the submittal for the conversion of the PTN Unit 3 and 4 CTS to the ISTS provides the proposed changes to the CTS, discussion of changes for the proposed CTS changes, the PTN Unit 3 and Unit 4 ITS and ITS Bases, as marked up utilizing NUREG-1431, and justification for deviations from the NUREG.

Volume 1 Volume 1 provides details concerning the application of the selection criteria to the PTN Unit 3 and Unit 4 CTS. Each CTS Specification is evaluated, and a determination is made as to whether the CTS Specification meets the criteria in 10 CFR 50.36(c)(2)(ii) for retention in the proposed ITS.
Volume 2 Volume 2 contains generic evaluations required by 10 CFR 50.91(a), which support a finding of No Significant Hazards Consideration (NSHC). Based on the inherent similarities in the NSHC evaluations, generic evaluations for a finding of NSHC have been provided for the following categories of CTS changes:
* Administrative Changes
* More Restrictive Changes
* Relocated Specifications E1-3
* Removed Detail Changes
* Less Restrictive Changes - Category 1 - Relaxation of LCO Requirements
* Less Restrictive Changes - Category 2 - Relaxation of Applicability
* Less Restrictive Changes - Category 3 - Relaxation of Completion Time
* Less Restrictive Changes - Category 4 - Relaxation of Required Action
* Less Restrictive Changes - Category 5 - Deletion of Surveillance Requirement
* Less Restrictive Changes - Category 6 - Relaxation of Surveillance Requirement Acceptance Criteria
* Less Restrictive Changes - Category 7 - Relaxation of Surveillance Frequency
* Less Restrictive Changes - Category 8 - Deletion of Surveillance Requirement Shutdown Performance Requirements
* Less Restrictive Changes - Category 9 - Deletion of Reporting Requirements For less restrictive changes not covered by a generic Less Restrictive Change category, specific NSHC evaluations have been provided in the applicable Chapter, Section, or Specification in Volumes 3 through 16. Additionally, specific NSHC evaluations have been provided for changes that have been identified beyond the CTS and the ISTS consistent with the guidance of TSTF-GG-13-01.
In addition, Volume 2 contains an evaluation of environmental consideration in accordance with 10 CFR 51.21. It has been determined that the proposed license amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(b), and no environmental impact statement or environmental assessment need be prepared in connection with the proposed license amendment.
Volumes 3 through 16 Volumes 3 through 16 provide the details and justification to support the proposed changes. Each volume contains the required information to review the conversion to ITS, and include the following:
* Individual Chapter, Section, or Specification, as applicable, in ITS order.
* Relocated/Deleted CTS Specifications (if applicable); and
* ISTS Specifications not adopted in the PTN Unit 3 and Unit 4 ITS (if applicable).
The information for each Chapter, Section, and Specification, as applicable, is organized as follows:
CTS Markup and Discussion of Changes (DOCs)
This section contains a markup of the CTS pages, either for CTS pages associated with an Individual ITS Specification or for Relocated/Deleted CTS Specifications, and the DOCs from the CTS. Other CTS license amendment requests under NRC review, as described in Enclosure 4 of this submittal, are not linked to this license amendment request and have not been incorporated in the proposed change.
The CTS markup pages for each ITS Specification are normally in numerical order.
However, more than one CTS Specification is sometimes used in the generation of an ITS Specification. In this case, the CTS pages that are the major contributor to the ITS E1-4

Specification are shown first, followed by the remaining associated CTS pages in numerical order.
The left-hand margin of the CTS markup pages includes a cross-reference to the equivalent ITS requirement. The upper right-hand corner of the CTS markup pages is annotated with the ITS Specification number to which it applies. Items on the CTS markup pages that are addressed in other proposed ITS Chapters, Sections, or Specifications are annotated with the appropriate reference.
The CTS markup pages are annotated with an alphanumeric designator to identify the differences between the CTS and the proposed ITS. The designator corresponds to a DOC, which provides the description and justification of the change to the CTS. The DOCs are located directly following the associated CTS markup for each Chapter, Section, or Specification, as applicable.
Each proposed change to the CTS is designated as one of the following DOC categories:
Designator     Category A         ADMINISTRATIVE CHANGES - Changes to the CTS that do not result in new requirements or change operational restrictions or flexibility.
These changes are supported in aggregate by a single generic NSHC.
M         MORE RESTRICTIVE CHANGES - Changes to the CTS that result in added restrictions or reduced flexibility. These changes are supported in aggregate by a single generic NSHC.
R         RELOCATED SPECIFICATIONS - Changes to the CTS that relocate specifications that do not meet the selection criteria of 10 CFR 50.36(c)(2)(ii). These changes are supported in aggregate by a single generic NSHC.
LA        REMOVED DETAIL CHANGES - Changes to the CTS that eliminate detail and relocate the detail to a licensee controlled document.
Typically, this involves details of system design and function, or procedural detail on methods of conducting a Surveillance Requirement.
These changes are supported in aggregate by a single generic NSHC.
In addition, the generic type of removed detail change is identified in italics at the beginning of the DOC.
L         LESS RESTRICTIVE CHANGES - Changes to the CTS that result in reduced restrictions or added flexibility. These changes are supported either in aggregate by a generic NSHC that addresses a particular category of less restrictive change, or by a specific NSHC if the change is not covered by one of the generic categories of less restrictive changes. If the less restrictive change is covered by a generic NSHC, the category of the change is identified in italics at the beginning of the DOC.
E1-5

The DOCs are numbered sequentially within each letter designator for each ITS Chapter, Section, or Specification.
The CTS Bases pages are replaced in their entirety by the proposed PTN Unit 3 and Unit 4 ITS Bases. Therefore, the CTS Bases markup pages are not provided in the ITS submittal.
ISTS Markup and Justification for Deviations (JFDs)
This section contains a markup of the NUREG-1431, Volume 1, ISTS pages, either for ISTS pages associated with an Individual ITS Specification or ISTS Specifications not adopted in the PTN ITS, and JFDs from the ISTS. The ISTS pages are annotated with a numeric designator to identify the differences between the ISTS and the proposed ITS. The designator corresponds to a JFD, which provides the justification for the difference. The JFDs are located directly following the associated ISTS markup for each Chapter, Section, or Specification, as applicable.
The left-hand margin of the ISTS markup pages includes a cross-reference to the equivalent CTS requirement.
ISTS Bases Markup and JFDs This section contains a markup of the NUREG-1431, Volume 2, ISTS Bases pages, either for ISTS Bases pages associated with an Individual ITS Specification or ISTS Specifications not adopted in the PTN Unit 3 and 4 ITS, and JFDs from the ISTS Bases. The ISTS Bases pages are annotated with a numeric designator to identify the differences between the ISTS Bases and the proposed ITS Bases. The designator corresponds to a JFD, which provides the justification for the difference. Where a JFD is applicable to only Unit 3 or Unit 4, it is identified as such at the beginning of the JFD in bold text. The Bases JFDs are located directly following the associated ISTS Bases markup for each Chapter, Section, or Specification, as applicable. The volumes for ITS Chapters 1.0, 4.0, and 5.0 do not include this section, because NUREG-1431 does not include any Bases for these Chapters.
Determination of NSHC This section contains the determination in accordance with 10 CFR 50.91(a)(1) using the criteria of 10 CFR 50.92(c) to support a finding of NSHC. For changes covered by a generic NSHC, the generic NSHCs are in Volume 2. For less restrictive changes not covered by a generic less restrictive category or have been determined to be a change beyond the CTS and the ITS, a specific NSHC evaluation has been performed. Each evaluation is annotated to correspond to the DOC discussed in the specific NSHC evaluation. For ITS Chapters, Sections, or Specifications for which the changes are covered by a generic NSHC evaluation, a statement that there are no specific NSHCs is provided.
