Since these files control vital processes during quantification, independent review and thorough documentation is needed to ensure that the quantification results do not exclude valid failure sequences. The current mutually exclusive events file (PTN2KMEE.TXT) was changed as a result of the addition of new T&M events for LC/SWGR HVAC AHUs and Sump Level Indicators. The calculation package includes a description of "add double maintenance events for these basic events to mutually exclusive events." However, no justification for making the events mutually exclusive or specifying the combinations that are mutually exclusive is provided. In addition, the review of the mutually exclusive events file indicates that some complimentary combinations related to AFW pump maintenance may not be included. While this would lead to conservative results due to failure to remove invalid cutsets, the addition of inappropriate mutually exclusive combinations would have the opposite result. Similar errors can be introduced 34 | Since these files control vital processes during quantification, independent review and thorough documentation is needed to ensure that the quantification results do not exclude valid failure sequences.

If core uncovery has been used as the core damage criterion in the available Turkey Point MAAP analyses, it is possible that some scenarios for which success credit was not taken may in fact be successful.

1.0 DESCRIPTION
The proposed amendment would modify the Turkey Point Nuclear Plant (Turkey Point),
Units 3 and 4 Technical Specifications (TS) by relocating specific surveillance frequencies to a licensee-controlled program with the adoption of Technical Specification Task Force (TSFT)-425, Revision 3, "Relocate Surveillance Frequencies to Licensee Control - Risk Informed Technical Specification Task Force (RITSTF) Initiative 5b"
[Reference 1]. Additionally, the change would add a new program, the Surveillance Frequency Control Program (SFCP) to TS Section 6.0, Administrative Controls, Subsection 6.8, Procedures and Programs. The changes are consistent with NRC approved industry / TSTF Standard Technical Specifications (STS) change TSTF-425, Revision 3. Federal Register "Notice of Availability of Technical Specification Improvement to Relocate Surveillance Frequencies to Licensee Control - Risk Informed Specification Task Force (RITSTF) Initiative 5b, Technical Specification Task Force -
425, Revision 3," published on July 6, 2009 (74 FR 31996) [Reference 2] announced the availability of this TS improvement.
2.0 ASSESSMENT 2.1 Applicability of Published Safety Evaluation Florida Power and Light Company (FPL) has reviewed the safety evaluation dated July 6, 2009. The review included a review of the NRC staff's evaluation, TSTF-425, Revision 3, and the requirements specified in Nuclear Energy Institute (NEI) 04-10, Revision 1 "Risk-Informed Method for Control of Surveillance Frequencies,"
[Reference 3].
Attachment 2 includes FPL's documentation with regard to PRA technical adequacy consistent with the requirements of Regulatory Guide (RG) 1.200, Revision 1, "An Approach for Determining the Technical Adequacy of Probabilistic Risk Assessment Results in Risk-Informed Activities," [Reference 4], Section 4.2, and describes any Probabilistic Risk Assessment (PRA) models without NRC-endorsed standards, including documentation of the quality characteristics of those models in accordance with RG 1.200.
FPL has concluded that the justifications presented in the TSTF proposal and the safety evaluation prepared by the NRC staff are applicable to Turkey Point Units 3 and 4 and justify this amendment to incorporate the changes to the Turkey Point TS.
2.2 Optional Changes and Variations The proposed amendment is consistent with STS changes described in TSTF-425, Revision 3, but FPL proposes variations or deviations from TSTF-425, as described below:
- 1. Revised (clean) TS pages are not included in this amendment request given the number of TS pages affected, the straightforward nature of the proposed changes, and outstanding license amendment requests that may affect some of the same TS pages. Providing only mark-ups of the proposed TS changes satisfies the requirements of 10 CFR 50.90, "Application for amendment of license, construction permit, or early site permit," in that the mark-ups fully describe the changes desired.

Turkey Point Units 3 and 4 L-2014-033 Docket Nos. 50-250 and 50-251 Attachment 1 This is an administrative deviation from the NRC staffs model application dated July 6, 2009 (74 FR 31996) with no impact on the NRC staffs model safety evaluation published in the same Federal Register Notice. As a result of this deviation, the contents and numbering of the attachments for this amendment request differ from the attachments specified in the NRC staff's model application.
- 2. The Turkey Point TS were based on the standard TS at the time they were issued.
As a result, the Turkey Point TS surveillance numbers and associated Bases numbers differ from the surveillance numbers and Bases numbers in NUREG-1431, "Standard Technical Specifications -Westinghouse Plants," Revision 4, Volumes 1 and 2 [Reference 5] and TSTF-425, Revision 3. In addition, the Administrative Controls Section TS is Section 6.0 for Turkey Point verses Section 5.0 for NUREG-1431. These differences are administrative deviations from TSTF-425 with no impact on the NRC staffs model safety evaluation dated July 6, 2009 (74 FR 31996).
There are surveillances contained in NUREG-1431 that are not contained in the Turkey Point TS. These surveillances identified in TSTF-425 for NUREG-1431 are not applicable to Turkey Point. This is an administrative deviation from TSTF-425 with no impact on the NRC staffs model safety evaluation dated July 6, 2009 (74 FR 31996).
- 3. The Turkey Point TS include plant-specific surveillances that are not contained in NUREG-1431 and, therefore are not included in the NUREG-1431 surveillances provided in TSTF-425. FPL has determined that the relocation of the frequencies for these Turkey Point specific surveillances is consistent with TSTF-425, Revision 3, and with the NRC staffs model safety evaluation dated July 6, 2009 (74 FR 31996),
including the scope exclusions identified in Section 1.0, "Introduction," of the model safety evaluation, because the plant-specific surveillance frequencies involve fixed period frequencies. Changes to the frequencies for these plant-specific surveillances would be controlled under the SFCP.
The SFCP provides the necessary administrative controls to require that surveillances related to testing, calibration, and inspection are conducted at a frequency to assurethat the necessary quality of the systems and components is maintained, the facility operation will be within safety limits, and that the Limiting Conditions for Operation will be met. Changes to frequencies in the SFCP would be evaluated using the methodology and probabilistic risk guidelines contained in NEI 04-10, Revision 1, "Risk-Informed Technical Specifications Initiative 5b, Risk-Informed Method of Control of Surveillance Frequencies," as approved by NRC letter "Final Safety Evaluation for Nuclear Energy Institute (NEI) Topical Report (TR) 04-10, Revision 1, "Risk Informed Technical Specification Initiative 5b, "Risk-Informed Method for Control of Surveillance Frequencies(TAC No. MD61 11)," dated September 19, 2007 [Reference 6].
The NEI 04-10, Revision 1 methodology includes qualitative considerations, risk analyses, sensitivity studies and bounding analyses, as necessary, and recommended monitoring of the performance of systems, structures, and components (SSCs) for which frequencies are changed to assure that reduced testing does not adversely impact the SSCs. The NEI 04-10 Revision 1 methodology Page 3 of 6
Turkey Point Units 3 and 4 L-2014-033 Docket Nos. 50-250 and 50-251 Attachment 1 satisfies the five key safety principles specified in RG 1.177, "An Approach for Plant-Specific Risk-Informed Decision Making: Technical Specifications," dated August 1998 [Reference 7], relative to changes in surveillance frequencies.
Therefore, the proposed relocation of the Turkey Point-specific surveillance frequencies is consistent with TSTF-425 and with the NRC staff's model safety evaluation dated July 6, 2009 (74 FR 31996).
- 4. The definition of STAGGERED TEST BASIS is being retained in the Turkey Point TS Definition Section 1.0 since the terminology is being maintained in TS Surveillance Requirements in Sections 3/4.3, Instrumentation, 3/4.7, Plant Systems, and 3/4.8, Electrical Power Systems. In addition, the terminology is used in Section 6.8.4.k, "Control Room Envelop Habitability Program," which is not the subject of this amendment request and is not proposed to be changed. This is an administrative deviation from TSTF-425 with no impact on the NRC staffs model safety evaluation dated July 6, 2009 (74 FR 31996).
- 5. The insert provided in TSTF-425 for the TS Bases (Insert 2) states "The Surveillance Frequency is based on operating experience, equipment reliability, and plant risk and is controlled under the Surveillance Frequency Control Program." In a letter dated April 14, 2010 [Reference 8], the NRC staff agreed that the insert applies to surveillance frequencies that are relocated and subsequently evaluated and changed in accordance with the SFCP, but does not apply to frequencies relocated to the SFCP, but not changed. Therefore, the insert for the Bases is revised to "The Surveillance Frequency is controlled under the Surveillance Frequency Control Program." This is an administrative deviation from TSTF-425 with no impact on the NRC staffs model safety evaluation dated July 6, 2009 (74 FR 31996).
- 6. The Turkey Point TS were based on the standard TS at the time they were issued which did not contain Bases as comprehensive as those in NUREG-1431.
Therefore, many of the Bases mark-ups in TSTF-425 are not applicable to the Turkey Point TS. The proposed Bases changes in Attachment 4 revise only those Bases that currently discuss surveillance frequencies. This is an administrative deviation from TSTF-425 with no impact on the NRC staff's model safety evaluation dated July 6, 2009 (74 FR 31996). The existing Bases information describing the basis for the surveillance frequencies will be relocated to the Turkey Point SFCP.
- 7. The SR for the Reactor Trip System Instrumentation and Engineered Safety Features Actuation System Instrumentation in Turkey Point TS 3.3.1 and 3.3.2 are presented in tabular format, which is different from the format of the SR for the same instrumentation in NUREG-1431. To accommodate this difference, the proposed changes includes use of "SFCP" as a frequency notation in the tables that specify instrumentation SR. This is an administrative deviation from TSTF-425 due to differences in format between Turkey Point TS and NUREG-1431, which has no impact on the NRC staffs model safety evaluation dated July 6, 2009 (74 FR 31996).
- 8. TS Table 3.3-4, Action Statements, Action 27 is being revised to change "expect" to "except" and TS 3.7.1.2 is being revised to change "APPLICA81LITY" to "APPLICABILITY". These differences from TSTF-425 are editorial changes to correct existing typographical errors and have no impact on the NRC staffs model safety evaluation dated July 6, 2009 (74 FR 31996).

1.0 INTRODUCTION
The implementation of the Surveillance Frequency Control Program (SFCP, also referred to as Technical Specifications Initiative 5b) at Turkey Point Station will follow the guidance'provided in NEI 04-10, Revision 1 [Reference 1] in evaluating proposed surveillance test interval (STI) changes. The following steps of the risk-informed STI revision process are common to all proposed STI changes within the proposed licensee controlled program.
" Each proposed STI revision is reviewed to determine whether there are any commitments made to the NRC that may prohibit changing the interval. If there are no related commitments, or the commitments may be changed using a commitment change process based on NRC-endorsed guidance, then evaluation of the STI revision can proceed. If a commitment exists, and the commitment change process does not permit the change without NRC approval, then the STI revision cannot be implemented. Only after receiving NRC approval to change the commitment could a STI revision proceed.
" A qualitative analysis is performed for each STI revision that involves several considerations as explained in NEI 04-10, Revision 1.
- Each STI revision is reviewed by an expert panel, referred to as the Integrated Decision-making Panel (IDP), which is normally the same panel used for Maintenance Rule implementation, but with the addition of specialists with experience in surveillance tests and system or component reliability. Ifthe IDP approves the STI revision, the change is documented, implemented, and available for future audits by the NRC. Ifthe IDP does not approve the STI revision, the STI value is left unchanged.
- Performance monitoring is conducted as recommended by the IDP. In some cases, no additional monitoring may be necessary beyond that already conducted under the Maintenance Rule. Performance monitoring helps to confirm that no failure mechanisms related to the revised test interval are subsequently identified as sufficiently significant to alter the basis provided in the justification for the surveillance interval change.
" The IDP is responsible for periodic review of performance monitoring results. If it is determined that the time interval between successive performances of a surveillance test is a factor in the unsatisfactory performances of the surveillance, the IDP returns the STI back to the previously acceptable STI.
" In addition to the above steps, the Probabilistic Risk Assessment (PRA) is used, when possible, to quantify the effect of a proposed individual STI revision compared to acceptance criteria in NEI 04-10, Revision 1. Also, the cumulative impact of risk-informed STI revisions on PRA evaluations (i.e., internal events, external events, and shutdown) is compared to the risk acceptance criteria as delineated in NEI 04-10, Revision 1. For those cases where the STI cannot be modeled in the plant PRA (or where a particular PRA model does not exist for a given hazard group), a qualitative or bounding analysis is performed to provide justification for the acceptability of the proposed test interval change.
The NEI 04-10, Revision 1 methodology endorses the guidance provided in Regulatory Guide (RG) 1.200, Revision 1, "An Approach for Determining the Technical Adequacy of Probabilistic Risk Assessment Results for Risk-Informed Activities." The guidance in RG 3
1.200 indicates that the following steps should be followed when performing PRA assessments:
- 1. Identify the parts of the PRA used to support the application.
- Identify structures, systems, and components (SSCs), and operational characteristics that are affected by the application and how these are implemented in the PRA model.
- A definition of the acceptance criteria used for the application.
- 2. Identify the scope of risk contributors addressed by the PRA model.
If not full scope (i.e., internal events, external events, applicable modes),
identify appropriate compensatory measures or provide bounding arguments to address the risk contributors not addressed by the PRA model.
- 3. Summarize the risk assessment methodology used to assess the risk of the application.
- Include how the PRA model was modified to appropriately model the risk impact of the change request.
- 4. Demonstrate the technical adequacy of the PRA.
" Identify plant changes (design or operational practices) that have been incorporated at the site, but are not yet in the PRA model and justify why the change does not impact the PRA results used to support the application.
- Document peer review findings and observations that are applicable to the parts of the PRA required for the application, and for those that have not yet been addressed, justify why the significant contributors would not be impacted.
- Document that the parts of the PRA used in the decision are consistent with applicable standards endorsed by the RG (currently, RG 1.200, Revision 1, which includes only the internal events PRA standard).
Provide justification to show that where specific requirements in the standard are not adequately met, it will not unduly impact the results.
- Identify key assumptions and approximations relevant to the results used in the decision-making process.
Because of the broad scope of potential Initiative 5b applications and the fact that the impact of such assumptions differs from application to application, each of the issues encompassed in Items 1 through 3 will be covered with the preparation of each individual PRA assessment made in support of the individual STI interval requests. The purpose of the remaining portion of this attachment is to address the requirements identified in item 4 above.
This evaluation summarizes the assessment of the Turkey Point PRA capability as measured against the current ASME/ANS PRA Standard (ASME/ANS RA-Sa-2009)
[Reference 2], endorsed by NRC Regulatory Guide (RG) 1.200, Revision 2 [Reference 3]. While the NEI guidance document refers to RG 1.200, Revision 1, which includes 4
only the internal events PRA standard (ASME RA-Sb-2005), this evaluation addresses the broader scope of RG 1.200, Revision 2. This assessment addresses the technical adequacy of the Turkey Point PRA for use in risk-informed applications.
The assessment is based on a series of formal peer reviews and other technical reviews, documented in the peer review reports. This assessment uses the latest Turkey Point PRA model update [Reference 4] and internal flood analysis [Reference 5].
2.0 BACKGROUND
2.1 RG1.200 and PRA Standard The ASME/ANS PRA Standard (ASME/ANS RA-Sa-2009) has eight "parts" with technical elements, high level requirements (HLRs), and detailed supporting requirements (SRs). These parts represent the major classes of hazards included in a PRA:
e Part 2, internal events (addressed in Section 3.1),
e Part 3, internal flood (addressed in Section 3.1),
- Part 4, internal fire (addressed in Section 3.2),
e Part 5, seismic events (addressed in Section 3.2),
a Parts 6 to 9, other external hazard events (addressed in Section 3.2).
Note - Part 1 of the PRA Standard is introductory information and does not contain any requirements except configuration control (addressed in Section 3.3).
NRC Reg Guide 1.200, Revision 2 endorses this Standard with minor "clarifications."
The Standard supporting requirements allow the assessment of the portions of the PRA as Capability Category CC-I, CC-Il, or CC-Ill, with increasing scope and level of detail, plant-specificity, and realism. Thus, the overall assessment of PRA capability is the collection of the assessments of the hundreds of supporting requirements.
2.2 Turkey Point PRA History The Turkey Point PRA was originally developed in 1991 for the IPE submittal [Reference 6] as a Level 2 risk assessment of at-power operation of Turkey Point addressing internal events including fires and floods. This PRA was subject to a number of reviews, internal and external, during its preparation as well as extensive review by NRC through national labs following its publication. The first of these reviews consisted of normal engineering quality assurance practices carried out by the organization performing the analysis. A qualified individual with knowledge of PRA methods and plant systems performed an independent review of the results for each task. This represented a detailed check of the input to the PRA model and provided a high degree of quality assurance.
The second level of review was performed by plant personnel not directly involved with the development of the PRA model: This review was performed by individuals from Operations, Technical Staff, Training, and the Independent Safety Engineering Group, 5
who reviewed the system description notebooks and accident sequence description.
This provided diverse expertise with plant design and operations knowledge to review the system descriptions for accuracy.
The third level of review was performed by PRA experts from ERIN Engineering. This review provided broad insights on techniques and results based on experience from other plant PRAs. The review team reviewed the PRA development procedures, as well as the output products.
Comments obtained from all the review sources were incorporated, as appropriate, into the work packages and the final product. Following the Turkey Point IPE submittal to the NRC on June 25, 1991, it was reviewed extensively by the NRC and NRC contractors.
In fact, the Turkey Point IPE was one of the few IPE submittals to receive a Step 1 and a Step 2 review by the NRC. The Step 2 review consisted of a team of NRC representatives and contractors visiting FPL to conduct a week-long, extensive review of the Turkey Point IPE. Following these reviews, the Turkey Point IPE was revised in early 1992, and FPL received the NRC Safety Evaluation Report (SER) for the Turkey Point IPE on October 15, 1992. The SER concluded that the Turkey Point IPE had met the intent of GL 88-20.
The Turkey Point Internal Events Peer Review was performed in January 2002 using the NEI 00-02 process. Following the issuance of the ASME PRA Standard and Regulatory Guide 1.200 (RG 1.200), an internal gap analysis was performed where the findings from the original 2002 peer review were incorporated into the overall assessment of the PRA's quality with respect to the Standard's supporting requirements. The current Turkey Point gap analysis uses the RA-Sa-2009 version of the standard as endorsed by RG 1.200, Revision 2.
To supplement the original peer review and internal gap analysis, and to further verify the quality of the updated internal events model used in the Fire PRA, in April 2011, a focused peer review was performed assessing the human reliability analysis (HRA) and internal flooding analysis portions of the PRA using the latest PRA standard, ASME/ANS RA-Sa-2009, and Regulatory Guide 1.200, Rev. 2. The internal flooding analysis focused peer review was performed because the latest internal flooding analysis was a much more comprehensive analysis than the original screening analysis that was performed for the IPE [Reference 6]. Although the basic methods used for the HRA had not changed substantially, the HRA focused peer, review was performed because of the enhanced HRA dependency analysis and the use of the HRA Calculator software in the latest model, and the fact that HRA plays a significant role in the determination of the dominant sequences and overall risk profile.
Finally, a peer review was performed in October 2013, to assess portions of the PRA model which had received upgrades: 1) Common-cause failure analysis - use of alpha factors; 2) Level 2 analysis - upgrade to the latest methodology; and 3) Interfacing system LOCAs - upgrade to the latest methodology.
Significant findings from the peer reviews, along with their resolutions, are listed in the Enclosure.

Date Implemented.: / 3/2000 R-:d4 1 of 641 ' .' Unrfiltered 'Search This database is used to store the details of all modifications, proposed and actual, open or closed, for the Turkey Point PRA model. This includes findings and observations from peer reviews, self-assessments, and issues identified during use and update of the PRA model. The open items are all model enhancements or documentation issues, and have been judged not to significantly impact PRA model applications. Open items will be addressed in future PRA updates, based on the significance of the open item and the scope of the update.
As part of the PRA evaluation for each STI change request, a review of open model changes for Turkey Point will be performed and an assessment of the impact on the results of the application will be made prior to presenting the results of the risk analysis to the IDP. If a nontrivial impact is expected, then this may include the performance of additional sensitivity studies or PRA model changes to confirm the impact on the risk analysis.
2.4 Turkey Point PRA Capability Tarqet The target capability level for the Turkey Point PRA is Capability Category II(CC-II).
That is, the goal is to meet all supporting requirements (SRs) at least at the CC-Il level.
This is the maximum capability level needed by any foreseeable application.
Note that in many supporting requirements, the requirement spans all three capability categories. Thus, if the SR is met, it meets CC Ill. While CC II is the target, CC III is met in many SRs.
7
2.5 Assessment Process The assessment of PRA capability judges the Turkey Point PRA against each supporting requirement in the PRA Standard as "Meets" CC-I, CC-Il, or CC-Ill. If the PRA does not meet the requirements of category CC-Il for a specific SR, it is assessed as "Not Met."
This assessment is captured in a Microsoft Access database. There is a table in this database with the SR-by-SR assessments from industry peer reviews and internal self-assessments. There is a separate database with tables with Facts and Observations (F&Os) from the WOG peer review and the focused peer reviews, along with their status and resolutions.
3.0 EVALUATION The following sections describe the capability of the Turkey Point PRA for the major Standard parts.
3.1 Parts 2 and 3 - Internal Events and Internal Flooding The internal events portion of the Turkey Point PRA has been updated a number of times since the original IPE submittal.
As described in Section 2.2, there has been one global peer review, and focused peer reviews in the following areas: HRA, internal flooding, CCF, Level 2, and ISLOCA.
Three peer reviews have been conducted against internal event supporting requirements:
- In 2002, a review of all technical elements was performed using the industry PRA Certification process, the precursor to the PRA Standard. The 2002 peer review resulted in 60 findings and observations (2 "A"level, 28 "B" level, 28 "C" level, and 2 "S (Superior) level). All of the findings and observations have been addressed in the model updates following this peer review.
- In 2011, a focused peer review was performed for the elements IF and HR. This assessment replaced the 1999 peer review for those elements that were in scope. This review was done using the current PRA Standard (ASME/ANS RA-Sa-2009). The 2011 focused peer review resulted in 21 findings, 7 suggestions, and 1 strength. All of the findings and suggestions have been resolved, and, where changes were necessary, addressed in a model update.
- In 2013, a focused peer review was performed to review upgrades to the CCF, Level 2, and ISLOCA analyses. This review was done using the current PRA Standard (ASME/ANS RA-Sa-2009) and Regulatory Guide 1.200, Rev. 2. The peer review resulted in 11 findings and 2 suggestions. These findings and suggestions have not yet been resolved in the current PRA model, but will either be addressed via model updates before the implementation of 5b, or shown to have an insignificant impact on the 5b application.
Conclusion The findings and F&Os that have not yet been resolved will either be resolved in model updates before the implementation of the 5b application, or shown not to represent a significant deficiency in the analyses necessary to support the 5b application.
8
3.2 Parts 4 to 9 - External Events The NEI 04-10 methodology allows for STI change evaluations to be performed in the absence of quantifiable PRA models for all external hazards. For those cases where the STI cannot be modeled in the plant PRA (or where a particular PRA model does not exist for a given hazard group), a qualitative or bounding analysis is performed to provide justification for the acceptability of the proposed test interval change.
3.2.1 Part 4 - Internal Fire A fire PRA was performed for Turkey Point as part of the 1991 IPE submittal. Since it was done for the IPE, it was more of a screening analysis to discover any fire vulnerabilities than an attempt to determine a realistic estimate of core damage risk due to fire. It has not been updated since the original submittal.
Turkey Point is an NFPA-805 plant, and therefore has a fire PRA to support the NFPA-805 effort. The fire PRA uses the latest internal events PRA model as a basis. The Turkey Point NFPA-805 fire PRA uses NUREG/CR-6850 guidance as required by NFPA-805, and thus produces a conservative estimate of core damage risk due to fire.
A peer review of the Turkey Point (PTN) Fire PRA was performed in February 2010 at PTN using the NEI 07-12 Fire PRA peer review process, the combined PRA standard, ASME/ANS RA-Sa-2009, and RG 1.200, Revision 2. The purpose of this review was to provide a method for establishing the technical quality and adequacy of the Fire PRA for the spectrum of potential risk-informed plant licensing applications for which the Fire PRA may be used. The February 2010 PTN Fire PRA Peer Review was a full-scope review of all the Technical Elements of Part 4 of the ASME/ANS standard. This report was issued to PTN in April 2010 [Reference 8]. A subsequent peer review performed in March 2012 was a focused scope peer review addressing the FSS, HRA and PRM Technical Elements. The report was finalized and issued to PTN in May 2012
[Reference 9].
The Fire PRA update addressed the Supporting-Requirement-assessed deficiencies (i.e., Not Met or CCI). Completion of recommendations related to Supporting Requirement assessments and 'Finding' F&Os results in a Capability Category II assessment for the majority of the Supporting Requirements.
Conclusion Based on the completion of peer review recommendations and the assessment of deferred items, the Turkey Fire PRA is adequate to support this application, with the caveat that the PRA is a conservative representation of the fire risk from operation of Turkey Point Station. The Fire PRA model will be exercised to obtain quantitative fire risk insights, but refinements may need to be made on a case-by-case basis.
3.2.2 Part 5 - Seismic Events Turkey Point is sited in an area of very low seismicity. There is no seismic PRA for Turkey Point. For the seismic portion of the Turkey Point IPEEE (Reference 7), FPL used the FPL site-specific seismic program associated with Unresolved Safety Issue 9

3.2.4 Conclusion - External Events As stated earlier, the NEI 04-10 methodology allows for STI change evaluations to be performed in the absence of quantifiable PRA models for all external hazards.
Therefore, in performing the assessments for the other hazard groups, a qualitative or a bounding approach will be utilized in most cases. The Fire PRA model will be exercised to obtain quantitative fire risk insights but refinements may need to be made on a case-by-case basis. This approach is consistent with the accepted NEI 04-10 methodology.
3.3 PRA Model Maintenance and Control PRA model maintenance and control requirements are described in the PRA Standard, Section 1-5. These requirements are addressed in the current set of Nextera/FPL fleet procedures that address model maintenance and control:
EN-AA-105, Probabilistic Risk Assessment Program EN-AA-105-1000, PRA Configuration Control and Model Maintenance EN-AA-105-10000, Control of PRA Documentation and Evaluations
4.0 CONCLUSION
The Turkey Point PRA model of record fully meets all the requirements of Part 2 (Internal Events) and Part 3 (Internal Flood) of the current ASME/ANS PRA Standard.
All significant findings from peer reviews or other technical reviews have been addressed and closed.
Based on the completion of peer review recommendations and the assessment of deferred items, the Turkey Fire PRA is adequate to support this application, with the caveat that the PRA is a conservative representation of the fire risk from operation of Turkey Point Station. The Fire PRA model will be exercised to obtain quantitative fire risk insights, but refinements may need to be made on a case-by-case basis.
Seismic risk at Turkey Point is minimal and will not be a significant factor in the 5b application.
As stated earlier, the NEI 04-10 methodology allows for STI change evaluations to be performed in the absence of quantifiable PRA models for all external hazards.
Therefore, in performing the assessments for the other hazard groups, a qualitative or a bounding approach will be utilized in most cases. This approach is consistent with the accepted NEI 04-10 methodology.

- d. The success criteria for early core heat removal using the AFW system is described differently in the PTN System Analysis Notebook and the Accident Sequence Analysis Notebook. The fault tree modeling appears to be generally consistent with the criteria stated in the System Analysis Notebook. For example, the System Analysis Notebook states that for ATWS, the AFW system must supply flow from 2 AFW pumps through all six AFW control valves. In Table 8 of the Accident Sequence Analysis Notebook, the ATWS success criteria for AFW is stated as 2 AFW pumps to 3/3 SGs.
The structure of fault tree gate A0201 agrees with the System Notebook criteria rather than the Accident Sequence Analysis Notebook. Similar differences were noted in the success criteria descriptions related to the heat removal requirements for the Transient and Small-small LOCA sequences where the Accident Sequence Analysis only gives the pump success citeria without including the requirement to provide flow 15

With the myriad of redundant systems (1) The Turkey Point PRA model assumes equivalent to that provided which can trip the reactor, coupled with the further that ATWS is always the result of for the ESFAS logic and redundancy of the operating crew to manually trip the mechanical failures (control rod insertion :onsider adding system plant based on indicated parameters, it was deemed failure, trip breaker failure to open), such modeling for AFW to not worthwhile to produce a detailed model of the that a reactor trip signal will occur.

Further, common cause failure is not explicitly addressed for these gates, although there is a common cause failure "TRIP BREAKERS FAIL TO OPEN DUE TO COMMON CAUSE"; it isn't clear from the available documentation whether or not logic circuit common cause is included in this event. Further, it isn't clear that the possibility that signal failures leading to failure of both reactor trip and AFW startup or turbine trip, such that AMSAC actuation would be needed, have been addressed in this manner.
Development of a more detailed description of the ATWS fault tree logic should be considered.
(2) The AFW logic for ATWS sequences, where 2 pumps are required to provide flow to 3 steam generators, includes pump failures due to recirculation (i.e., "mini-flow") failures (e.g., Gate A0010). While this may normally be a valid failure mechanism for these pumps, it would seem that, with the high flowrates required for ATWS response, it would not apply under these conditions. Consider reviewing the basis for this modeling and correcting if necessary.

Since these files control vital processes during quantification, independent review and thorough documentation is needed to ensure that the quantification results do not exclude valid failure sequences. The current mutually exclusive events file (PTN2KMEE.TXT) was changed as a result of the addition of new T&M events for LC/SWGR HVAC AHUs and Sump Level Indicators. The calculation package includes a description of "add double maintenance events for these basic events to mutually exclusive events." However, no justification for making the events mutually exclusive or specifying the combinations that are mutually exclusive is provided. In addition, the review of the mutually exclusive events file indicates that some complimentary combinations related to AFW pump maintenance may not be included. While this would lead to conservative results due to failure to remove invalid cutsets, the addition of inappropriate mutually exclusive combinations would have the opposite result. Similar errors can be introduced 34

For the TPN Medium LOCA, i.e., breaks up to 13.5 inches, the PRA assumes that a single train of high head injection can mitigate this class of LOCAs, whereas typical PRAs would instead tend to credit a single train of low head injection for breaks at the upper end of this size range (i.e., above 6").
As noted above, analyses supporting the upper end of the Medium LOCA range with this success criterion were not available during the peer review.
MAAP 3.Ob analyses were used to support the definition of ECCS requirements for the MLOCA, even at the upper end of the break size range (i.e., 13 inches). In general, MAAP 3.Ob is not appropriate for rapid depressurizations as would be occurring for breaks in the MLOCA size range.

So, for those PRA success criteria for which the licensing basis analyses provide the success criteria bases, the 2200 degF value is appropriate. Where the MAAP code (or other codes / models with more simplified modeling detail than the licensing basis codes) is used, selection of a lower predicted temperature may be more appropriate.
If core uncovery has been used as the core damage criterion in the available Turkey Point MAAP analyses, it is possible that some scenarios for which success credit was not taken may in fact be successful. This is because in some events there may be a brief uncovery of the top of the core without gross fuel heatup, followed by refilling of the vessel as injection occurs.
Thus, some PRAs apply a combined temperature and onset of core uncovery, or temperature and time, criterion. It is not possible to determine from the available MAAP 3b analysis summary which cases might change, but the breaks in the S2 size range represent a set of cases where additional investigation might change requirements. Other criteria that could be examined include human action timing.

Measurement, at designated locations, of the CRE pressure relative to external areas adjacent to the CRE boundary during the pressurization mode of operation of the CREVS, operating at the flow rate required by Surveillance Requirement 4.7.5.d, at a Frequency of 18 months. Additionally, the supply fans (trains A and B) will be tested on a staggered test basis (defined in Technical Specification definition 1.29 every 36 months).
The results shall be trended and the CRE boundary assessed every 18 months.
- e. The quantitative limits on unfiltered air inleakage into the CRE. These limits shall be stated in a manner to allow direct comparison to the unfiltered air inleakage measured by the testing described in paragraph c. The unfiltered air inleakage limit for radiological challenges is the inleakage flow rate assumed in the licensing basis analyses of DBA consequences. Unfiltered air inleakage limits for hazardous chemicals must ensure that exposure of CRE occupants to these hazards will be within the assumptions in the licensing basis.

These provisions are intended to establish and confirm the position of the rod with the inoperable RPI to ensure that power distribution requirements are NOT violated.
The ACTION Statements which permit limited variations from the basic requirements are accompanied by additional restrictions which ensure that the original design criteria are met. Misalignment of a rod requires measurement of peaking factors and a restriction in THERMAL POWER. These restrictions provide assurance of fuel rod integrity during continued operation. In addition, those safety analyses affected by a misaligned rod are reevaluated to confirm that the results remain valid during future operation.
The maximum rod drop time restriction is consistent with the assumed rod drop time used in the safety analyses. Measurement with Tavg greater than or equal to 500OF and with all Reactor Coolant Pumps operating ensures that the measured drop times will be representative of insertion times experienced during a Reactor Trip at operating conditions.
Control rod positions and OPERABILITY of the Rod Position Indicators are required to be verified on a nominal basis of e,-ee per 12 h'-rc with more frequent verifications required if an automatic monitoring channel is inoperable. These verification frequencies are adequate for assuring that the applicable LCOs are satisfied.

The limits are consistent with the initial UFSAR assumptions and have been analytically demonstrated adequate to maintain a minimum DNBR above the applicable design limits throughout each analyzed transient.
The limits for Tavg and pressurizer pressure have been moved to the COLR. The measured RCS flow value of 270,000 gpm corresponds to a Thermal Design Flow of 260,700 gpm with an allowance of 3.5% to accommodate calorimetric measurement uncertainty.
The ,2 H-O periodic surveillance of these parameters through instrument readout is sufficient to ensure that the parameters are restored within their limits following load changes and other expected transient operation. The 1.8 Re*h periodic measurement of the RCS total flow rate is adequate to ensure that the DNB-related flow assumption is met and to ensure correlation of the flow indication channels with measured flow. The indicated percent flow surveillance z,-. a 1 2 huF ba.*,a will provide sufficient verification that flow degradation has NOT occurred. An indicated percent flow which is greater than the thermal design flow plus instrument channel inaccuracies and parallax errors is acceptable for the 12 he'.'

In MODE 5 only one Pressurizer Code Safety is required for overpressure protection. In lieu of an actual OPERABLE Code Safety Valve, an unisolated and unsealed vent pathway (i.e., a direct, unimpaired opening, a vent pathway with valves locked open and/or power removed and locked on an open valve) of equivalent size can be taken credit for as synonymous with an OPERABLE Code Safety.
Demonstration of the safety valves lift settings will occur only during shutdown and will be performed in accordance with the provisions of the ASME OM Code. The Pressurizer Code Safety Valves lift settings allows a +2%, -3% setpoint tolerance for OPERABILITY; however, the valves are reset to within +/-1% during the surveillance to allow for drift.
3/4.4.3 Pressurizer The l.Hetrr periodic surveillance is sufficient to ensure that the maximum water volume parameter is restored to within its limit following expected transient operation. The maximum water volume (1133 cubic feet) ensures that a steam bubble is formed and thus the RCS is NOT a hydraulically solid system. The requirement that both backup pressurizer heater groups be OPERABLE enhances the capability of the plant to control Reactor Coolant System pressure and establish natural circulation.

The RCS water inventory balance must be performed with the reactor at steady state operating conditions and near operating pressure. The Surveillance is modified by two notes.

Steady state operations is required to perform a proper inventory balance since calculations during maneuvering are NOT useful. For RCS operational leakage determination by water inventory balance, steady state is defined as stable RCS pressure, temperature, power level, Pressurizer and makeup tank levels, makeup and letdown, and Reactor Coolant Pump seal injection and return flows.
An early warning of PRESSURE BOUNDARY LEAKAGE or UNIDENTIFIED LEAKAGE is provided by the automatic systems that monitor containment atmosphere radioactivity, containment normal sump inventory and discharge, and reactor head flange leak-off. It should be noted that leakage past seals and gaskets is NOT PRESSURE BOUNDARY LEAKAGE. These leakage detection systems are specified in LCO 3.4.6.1, Reactor Coolant System Leakage Detection Systems.
Note ** states that this SR is NOT applicable to primary-to-secondary leakage because leakage of 150 gallons per day cannot be measured accurately by an RCS water inventory balance.

This SR verifies that primary-to-secondary leakage is less than or equal to 150 gpd through any one SG. Satisfying the primary-to-secondary leakage limit ensure that the operational leakage performance criterion in the Steam Generator Program is met. If this SR is NOT met, compliance with LCO 3.4.5, Steam Generator (SG)
Tube Integrity, should be evaluated. The 150-gpd limit is measured at room temperature as described in Reference 5. The operational leakage rate limit applies to leakage through any one SG. If it is NOT practical to assign the leakage to an individual SG, all the primary to secondary leakage should be conservatively assumed to be from one SG.
The SR is modified by Note ***, which states that the Surveillance is 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 establishment of steady state operation. For RCS primary to-secondary leakage determination, steady state is defined as stable RCS pressure, temperature, power level, pressurizer and makeup tank levels, makeup and letdown, and reactor coolant pump seal injection and return flows.
The surveillance frequency 4-e is a reasonable interval to trend primary to secondary leakage and recognizes the importance of early leakage detection in the prevention of accidents. The primary-to-secondary leakage is determined using continuous process radiation monitors or radiochemical grab sampling in accordance with the EPRI guidelines (Ref. 5).
SR 4.4.6.2.2 It is apparent that when pressure isolation is provided by two in-series check valves and when failure of one valve in the pair can go undetected for a substantial length of time, verification of valve integrity is required. Since these valves are important in preventing overpressurization and rupture of the ECCS low pressure piping, which could result in a LOCA that bypasses containment, these valves should be tested periodically to ensure low probability of gross failure.

Verifying Control Room indication applies to the valve position and NOT to the valve operator power removal. The breaker position may be verified by either the off condition of the breaker position indication light in the Control Room, or the verification of the locked open breaker position in the field. Verifying that power is removed to the applicable valve operators can be accomplished by direct field indication of the breaker (locked in the open position), or by observation of the breaker position status lamp in the Control Room (lamp is off when breaker is open). Surveillance Requirements for throttle valve position stops prevent total pump flow from exceeding runout conditions when the system is in its minimum resistance configuration.

3/4.6.2.3 Recirculation PH Control System The Recirculation pH Control System is a passive safeguard consisting of 10 stainless steel wire mesh baskets (2 large and 8 small) containing sodium tetra borate decahydrate (NaTB) located in the containment basement (14' elevation). The initial containment spray will be boric acid solution from the Refueling Water Storage Tank. The recirculation pH control system adds NaTB to the Containment Sump when the level of boric acid solution from the Containment Spray and the coolant lost from the Reactor Coolant System rises above the bottom of the buffering agent baskets. As the sump level rises, the NaTB will begin to dissolve. The addition of NaTB from the buffering agent baskets ensures the containment sump pH will be greater than 7.0. The resultant alkaline pH of the spray enhances the ability of the recirculated spray to scavenge fission products from the containment atmosphere. The alkaline pH in the recirculation sump water minimizes the evolution of iodine and minimizes the occurrence of chloride and caustic stress corrosion on stainless steel piping systems exposed to the solution.
The OPERABILITY of the recirculation pH control system ensures that there is sufficient NaTB available in the containment to ensure a sump pH greater than 7.0 during the recirculation phase of a postulated LOCA. The baskets will NOT interact with surrounding equipment during a seismic event.

To satisfy the surveillance requirement, the two large baskets and eight small baskets must contain a combined mass greater than 7500 Ibm of NaTB. As shown in the above table, this will ensure the sump pH exceeds 7.0 at the onset of spray recirculation and for the duration of the analyzed 30-day period. The large baskets have a length and width of 54 inches, and a height of 33.25 inches and are elevated 3.5 inches above the containment floor. The smaller baskets have a length and width of 36 inches and a height of 30 inches and are elevated 4.5 inches above the containment floor.
Varying basket dimensions or elevation (e.g. basket leg height) impacts the surface to volume ratio and changes the time the NaTB is in contact with containment sump water. For instance, shorter legs would allow the NaTB to contact containment sump water sooner, therefore increasing the pH at the onset of recirculation. Longer legs, however, would reduce the pH at the onset of recirculation. The level of NaTB in the baskets required to provide an equilibrium sump solution pH greater than 7.0 is 14.75 inches from the top of the "
basket; 18.50 inches for the large baskets and 15.25 inches for the small baskets from the bottom of the basket. The 1, e,,,th frequency for Surveillance Requirement 4.6.2.3 is sufficient to ensure that the stainless steel buffering agent baskets are intact and contain the required quantity of NaTB.

ACTION statement 3 describes the actions to be taken when a single Auxiliary Feedwater Pump is inoperable. The requirement to verify that two independent Auxiliary Feedwater Trains are OPERABLE is to be accomplished by verifying that the requirements for Table 3.7-3 have been successfully met for each train within the last surveillance interval.
The provisions of Specification 3.0.4 are NOT applicable to the third auxiliary feedwater pump provided it has NOT been inoperable for longer than 30 days. This means that a units can change OPERATIONAL MODES during a unit's heatup with a single Auxiliary Feedwater Pump inoperable as long as the requirements of ACTION Statement 3 are satisfied.
The specified flow rate acceptance criteria conservatively bounds the limiting AFW flow rate modeled in the single unit Loss Of Normal Feedwater analysis. Dual unit events such as a two unit Loss Of Offsite Power require a higher pump flow rate, but it is NOT practical to test both units simultaneously. The m, 4lp4h'flow surveillance test specified in 4.7.1.2.1.1 is considered to be a general performance test for the AFW system and does NOT represent the limiting flow requirement for AFW.

The -hthly testing of the Auxiliary Feedwater Pumps will verify their OPERABILITY. Proper functioning of the turbine admission valve and the operation of the pumps will demonstrate the integrity of the system.
Verification of correct operation will be made both from instrumentation within the Control Room and direct visual observation of the pumps.

Inoperable FCVs and FIVs that are closed or isolated must be verified on a periodic basis that they are closed or isolated. This is necessary to ensure that the assumptions in the safety analysis remain valid.
The 7 day Completion Time is reasonable in view of valve status indications available in the Control Room, and other administrative controls, to ensure that these valves are closed or isolated.
With two valves in the same flow path inoperable, there may be NO redundant system to operate automatically and perform the required safety function. Although the Containment can be isolated with the failure of two valves in parallel in the same flow path, the double failure can be an indication of a common mode failure in the valves of this flow path, and as such, is treated the same as a loss of the isolation capability of this flow path. Under these conditions, affected valves in each flow path must be restored to OPERABLE status, or the affected flow path isolated within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />. This action returns the system to the condition where at least one valve in each flow path is performing the required safety function. The 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> Completion Time is reasonable, based on operating experience, to complete the actions required to close the FCV or FIV, or otherwise isolate the affected flow path.
SR 4.7.1.7.a verifies that each FCV, FIV, and bypass line valve will actuate to its isolation position on an actuation or simulated actuation signal. The 18-I*mth Frequency is based on a refueling cycle interval and the potential for an unplanned transient if the Surveillance were performed with the reactor at power. Operating experience has shown that these components usually pass this Surveillance when performed at the 18 month Frequency. Therefore, the frequency was concluded to be acceptable from a reliability standpoint.
SR 4.7.1.7.b verifies that the closure time of each FCV, FIV, and bypass line valve, when tested in accordance with the Inservice Testing Program, is within the limits assumed in the accident and containment analyses. This SR is normally performed upon returning the unit to operation following a refueling outage. These valves should NOT be tested at power, since even a part stroke exercise increases the risk of a valve closure with the unit generating power. This is consistent with the ASME Code Section XI (Ref. 3), quarterly stroke requirements during operation in MODES 1 and 2.

In addition to the predetermined restrictions, assessments performed in accordance with the provisions of the Maintenance Rule (a)(4) will ensure that any other risk significant configurations are identified before removing an EDG from service for pre-planned maintenance.
A configuration risk management program has been established at Turkey Point 3 and 4 via the implementation of the Maintenance Rule and the On line Risk Monitor to ensure the risk impact of out of service equipment is appropriately evaluated prior to performing any maintenance activity.
The Surveillance Requirements for demonstrating the OPERABILITY of the diesel generators are in accordance with the recommendations of Regulatory Guides 1.9, Selection of Diesel Generator Set Capacity for Standby Power Supplies, March 10, 1971; 1.108, Periodic Testing of Diesel Generator Units Used as Onsite Electric Power Systems at Nuclear Power Plants, Revision 1, August 1977; and 1.137, Fuel-oil Systems for Standby Diesel Generators, Revision 1, October 1979.

Failure to meet any of the above limits is cause for rejecting the new fuel oil, but does NOT represent a failure to meet the Limiting Condition for Operation of TS 3.8.1.1, since the new fuel oil has NOT been added to the Diesel Fuel Oil Storage Tanks.
Within 30 days following the initial new fuel oil sample, the fuel oil is analyzed to establish that the other properties specified in Table 1 of ASTM-D975-81 are met when tested in accordance with ASTM-D975-81 except that the analysis for sulfur may be performed in accordance with ASTM-D1552-79 or ASTM-D2622-82. The 30 day period is acceptable because the fuel oil properties of interest, even if they are NOT within limits, would NOT have an immediate effect on EDG operation. The Diesel Fuel Oil Surveillance in accordance with the Diesel Fuel Oil Testing Program will ensure the availability of high quality diesel fuel oil for the EDGs.
Lubricity Specification for Ultra Low Sulfur Diesel Fuel Oil To ensure that Ultra Low Sulfur Diesel fuel (15 pm sulfur, S15) is acceptable for use in the Emergency Diesel Generators, a test is added in the Diesel Fuel Oil Testing Program that validates, satisfactory lubricity (
Reference:
Engineering Evaluation PTN-ENG-SEMS-06-0035).
The test for lubricity is based on ASTM D975-06, testing per ASTM D6079, using the High Frequency Reciprocating Rig (HFRR) test at 60 degrees C and the acceptance criterion requires a wear scar NO 3 larger than 520 microns.
Ott least... ever;y -.. dys, a sample of fuel oil is obtained from the storage tanks in accordance with ASTM-D2276-78. The particulate contamination is verified to be less than 10 mg/liter when checked in accordance with ASTM-D2276-78, Method A. It is acceptable to obtain a field sample for subsequent laboratory testing in lieu of field testing.
Fuel oil degradation during long term storage shows up as an increase in particulate, due mostly to oxidation. The presence of particulate does NOT mean the fuel oil will NOT burn properly in a diesel engine.
The particulate can cause fouling of filters and fuel oil injection equipment, however, which can cause engine failure.

O-ADM-536 TURKEY POINT PLANT ATTACHMENT 2 Technical Specification Bases (Page 166 of 176) 3/4.9 Refueling Operations 3/4.9.1 Boron Concentration The limitations on reactivity conditions during REFUELING ensure that:
(1) The reactor will remain subcritical during CORE ALTERATIONS, and (2) A uniform boron concentration is maintained for reactivity control in the water volume having direct access to the reactor vessel.
These limitations are consistent with the initial conditions assumed for the boron dilution incident in the safety analyses. With the required valves closed during refueling operations the possibility of uncontrolled boron dilution of the filled portion of the RCS is precluded. This action prevents flow to the RCS of unborated water by closing flow paths from sources of unborated water. The boration rate requirement of 16 gpm of 3.0 wt% (5245 ppm) boron or equivalent ensures the capability to restore the SHUTDOWN MARGIN with one OPERABLE charging pump.
The OPERABILITY of the Source Range Neutron Flux Monitors ensures that redundant monitoring capability is available to detect changes in the reactivity condition of the core. There are four source range neutron flux channels, two primary, and two backup. All four channels have visual and alarm indication in the Control Room and interface with the containment evacuation alarm system. The primary source range neutron flux channels can also generate reactor trip signals and provide audible indication of the count rate in the Control Room and containment. At least one primary source range neutron flux channel to provide the required audible indication, in addition to its other functions, and one of the three remaining source range channels shall be OPERABLE to satisfy the LCO.

Turkey Point Units 3 and 4 L-2014-033 Docket Nos. 50-250 and 50-251 Attachment 5 No Significant Hazards Consideration Description of Amendment Request:
The change requests the adoption of an approved change to the Standard Technical Specifications (STS) for Westinghouse Plants (NUREG-1431) to allow relocation of specific TS surveillance frequencies to a licensee-controlled program. The proposed change is described in Technical Specification Task Force (TSTF) Traveler, TSTF-425, Revision 3 (ADAMS Accession No. ML090800642) related to the Relocation of Surveillance Frequencies to Licensee Control -
RITSTF Initiative 5b and was described in the Notice of Availability published in the Federal Register on July 6, 2009 (74 FR 31966).
The proposed changes are consistent with NRC-approved industry/ TSTF Traveler TSTF-425, Revision 3, "Relocate Surveillance Frequencies to Licensee Control - RITSTF Initiative 5b."
The proposed change relocates surveillance frequencies to a licensee-controlled program, the Surveillance Frequency Control Program. This change is applicable to licensees using probabilistic risk guidelines contained in NRC approved Nuclear Energy Institute (NEI) 04-10, "Risk-Informed Technical Specifications Initiative 5b, Risk-Informed Method for Control of Surveillance Frequencies," (ADAMS Accession No. ML071360456).
Surveillance frequencies that have a set periodicity will be relocated to the Surveillance Frequency Control Program controlled by the licensee. Accordingly, changes to the periodicity can be made without prior NRC approval, provided they are made within the constraints of the Program. These constraints include, but are not limited to an engineering evaluation, an assessment of the risk associated with the change, and a review by an independent decision-making panel.
Basis for proposed no significant hazards consideration:
As required by 10 CFR 50.91(a), the FPL analysis of the issue of no significant hazards consideration is presented below:
- 1. Does the proposed change involve a significant increase in the probability or consequences of any accident previously evaluated?
Response: No The proposed change relocates the specified frequencies for periodic surveillance requirements to licensee control under a new Surveillance Frequency Control Program.
Surveillance frequencies are not an initiator to any accident previously evaluated. As a result, the probability of any accident previously evaluated is not significantly increased.
The systems and components required by the technical specifications for which the surveillance frequencies are relocated are still required to be operable, meet the acceptance criteria for the surveillance requirements, and be capable of performing any mitigation function assumed in the accident analysis. As a result, the consequences of any accident previously evaluated are not significantly increased.
Therefore, the proposed change does not involve a significant increase in the probability or consequences of any accident previously evaluated.
Page 2 of 3
Turkey Point Units 3 and 4 L-2014-033 Docket Nos. 50-250 and 50-251 Attachment 5
- 2. Does the proposed change create the possibility of a new or different kind of accident from any previously evaluated?
Response: No The proposed changes relocate the surveillance frequencies for Surveillance Requirements that have a set periodicity from the TS to a licensee controlled Surveillance Frequency Control Program. This change does not alter any existing surveillance frequencies. Within the constraints of the Program, the licensee will be able to change the periodicity of these surveillance requirements. Relocating the surveillance frequencies does not impact the ability of structures, systems or components (SSCs) from performing there design functions, and thus, does not create the possibility of a new or different kind of accident from any previously evaluated.
No new or different accidents result from utilizing the proposed change. The changes do not involve a physical alteration of the plant (i.e., no new or different type of equipment will be installed) or a change in the methods governing normal plant operation. In addition, the changes do not impose any new or different requirements. The changes do not alter assumptions made in the safety analysis assumptions and current plant operating practice.
Therefore, the proposed changes do not create the possibility of a new or different kind of accident from any accident previously evaluated.
- 3. Does the proposed change involve a significant reduction in the margin of safety?
Response: No The design, operation, testing methods, and acceptance criteria for systems, structures, and components (SSCs), specified in applicable codes and standards (or alternatives approved for use by the NRC) will continue to be met as described in the plant licensing basis (including the final safety analysis report and bases to TS), since these are not affected by changes to the surveillance frequencies. Similarly, there is no impact to safety analysis acceptance criteria as described in the plant licensing basis. To evaluate a change in the relocated surveillance frequency, FPL will perform a probabilistic risk evaluation using the guidance contained in NRC-approved NEI 04-10, Revision 1 in accordance with the TS Surveillance Frequency Control Program. NEI 04-10, Revision 1, methodology provides reasonable acceptance guidelines and methods for evaluating the risk increase of proposed changes to surveillance frequencies consistent with Regulatory Guide (RG) 1.177, An Approach for Plant-Specific Risk-Informed Decision-Making: Technical Specifications.
Therefore, the proposed changes do not involve a significant reduction in a margin of safety.
Based upon the discussion above, FPL concludes that the requested change does not involve a significant hazards consideration as set forth in 10 CFR 50.92(c), Issuance of Amendment.
