RIVER BEND STATION. UNIT 1 DOCKET NO. 50-458

1.0 INTRODUCTION

By application dated February 28, 2018 (Reference 1), as supplemented by letters dated July 10, July 24, December 17, and December 20, 2018 (References 2, 3, 4, and 5, respectively), Entergy Operations, Inc. (Entergy, the licensee) submitted a request for changes to the technical specifications (TSs) for River Bend Station, Unit 1 (RBS).

The proposed changes would modify the TSs to adopt the U.S. Nuclear Regulatory Commission (NRC)-approved Technical Specifications Task Force (TSTF) Standard Technical Specifications (STSs) Change Traveler TSTF-425, Revision 3, "Relocate Surveillance Frequencies to Licensee Control - RITSTF [Risk-Informed TSTF] Initiative 5b" (Reference 6) for RBS.

The supplemental letters dated July 10, July 24, December 17, and December 20, 2018, provided additional information that clarified the application, 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 Federal Register (FR) on May 22, 2018 (83 FR 23733).

2.0 REGULATORY EVALUATION

2.1 Description of the Proposed Changes The licensee proposed to modify the TSs by relocating specific surveillance requirement (SR) frequencies to a licensee-controlled program in accordance with Nuclear Energy Institute (NEI) 04-10, Revision 1 (Reference 7). The licensee stated that the proposed change is consistent with the adoption of NRG-approved TSTF-425, Revision 3. When implemented, TSTF-425 allows licensees to relocate most periodic frequencies of TS SRs to a licensee-controlled program, referred to as the Surveillance Frequency Control Program Enclosure 2

(SFCP), and provides requirements for the new program in the Administrative Controls section of the TSs. All surveillance frequencies can be relocated except the following:

Frequencies that reference other approved programs for the specific interval such as the lnservice Testing Program or the Primary Containment Leakage Rate Testing Program;

Frequencies that are purely event-driven (e.g., "each time the control rod is withdrawn to the 'full out' position");

Frequencies that are event-driven, but have a time component for performing the surveillance on a one-time basis once the event occurs (e.g., "within 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months after thermal power reaching ~ [greater than or equal to] 95% RTP [rated thermal power]"); and

Frequencies that are related to specific conditions (e.g., battery degradation, age and capacity) or conditions for the performance of a surveillance requirement (e.g.,

"drywall to suppression chamber differential pressure decrease").

The licensee proposed to relocate specific surveillance frequencies from the following TS sections to the SFCP:

3.1 Reactivity Control System 3.2 Power Distribution Limits 3.3 Instrumentation 3.4 Reactor Coolant System (RCS) 3.5 Emergency Core Cooling Systems (ECCS), Reactor Pressure Vessel (RPV)

Water Inventory Control, and Reactor Core Isolation Cooling (RCIC) System 3.6 Containment Systems

3. 7 Plant Systems 3.8 Electrical Power Systems 3.9 Refueling Operations

3. 1O Special Operations The licensee proposed to add the SFCP to RBS TS Chapter 5.0, "Administrative Controls."

Proposed TS 5.5.12, "Surveillance Frequency Control Program," describes the requirements for the SFCP to control changes to the relocated surveillance frequencies to ensure that surveillances are performed at intervals to ensure limiting conditions for operation (LCOs) are met. The TS Bases for each affected surveillance would be revised to state that the surveillance frequency is controlled under the SFCP, and were included in the application for information only. The proposed changes to the Administrative Controls section of the TSs include a specific reference to NEI 04-10, Revision 1, as the basis for making any changes to the surveillance frequencies when they are relocated out of the TSs.

In a letter dated September 19, 2007 (Reference 8), the NRC staff approved Topical Report NEI 04-10, Revision 1, as an acceptable methodology for referencing in licensing actions to the extent specified in NEI 04-10, Revision 1, and under the limitations and conditions delineated in the safety evaluation (SE) providing the basis for NRC acceptance of NEI 04-10, Revision 1.

The licensee proposed other changes and deviations from TSTF-425, which are discussed in SE Section 3.3, "Deviations from TSTF-425 and Other Changes."

2.2 Applicable Commission Policy Statements In the "Final Policy Statement: Technical Specifications Improvements for Nuclear Power Reactors," dated July 22, 1993 (58 FR 39132), the NRC addressed the use of probabilistic safety analysis (PSA, currently referred to as probabilistic risk assessment or PRA) in STS. In this 1993 publication, the NRC states (at 39135):

The Commission believes that it would be inappropriate at this time to allow requirements which meet one or more of the first three criteria [of Title 10 of the Code of Federal Regulations (10 CFR), Section 50.36(a)(2)(ii)] to be deleted from Technical Specifications based solely on PSA (Criterion 4). However, if the results of PSA indicate that Technical Specifications can be relaxed or removed, a deterministic review will be performed ....

The Commission Policy in this regard is consistent with its Policy Statement on "Safety Goals for the Operation of Nuclear Power Plants," 51 FR 30028, published on August 21, 1986. The Policy Statement on Safety Goals states in part, "* *

probabilistic results should also be reasonably balanced and supported through use of deterministic arguments. In this way, judgments can be made * *

about the degree of confidence to be given these [probabilistic]

estimates and assumptions. This is a key part of the process of determining the degree of regulatory conservatism that may be warranted for particular decisions.

This defense-in-depth approach is expected to continue to ensure the protection of public health and safety." ...

The Commission will continue to use PSA, consistent with its policy on Safety Goals, as a tool in evaluating specific line-item improvements to Technical Specifications, new requirements, and industry proposals for risk-based Technical Specification changes.

Approximately 2 years later, the NRC provided additional detail *concerning the use of PRA in the "Final Policy Statement: Use of Probabilistic Risk Assessment Methods in Nuclear Regulatory Activities," dated August 16, 1995 (60 FR 42622). In this publication, the NRC states, in part:

The Commission believes that an overall policy on the use of PRA methods in nuclear regulatory activities should be established so that the many potential applications of PRA can be implemented in a consistent and predictable manner that would promote regulatory stability and efficiency. In addition, the Commission believes that the use of PRA technology in NRC regulatory activities should be increased to the extent supported by the state-of-the-art in PRA methods and data and in a manner that complements the NRC's deterministic approach ...

PRA addresses a broad spectrum of initiating events by assessing the event frequency. Mitigating system reliability is then assessed, including the potential for multiple and common cause failures. The treatment therefore goes beyond the single failure requirements in the deterministic approach. The probabilistic approach to regulation is, therefore, considered an extension and enhancement

of traditional regulation by considering risk in a more coherent and complete manner....

Therefore, the Commission believes that an overall policy on the use of PRA in nuclear regulatory activities should be established so that the many potential applications of PRA can be implemented in a consistent and predictable manner that promotes regulatory stability and efficiency. This policy statement sets forth the Commission's intention to encourage the use of PRA and to expand the scope of PRA applications in all nuclear regulatory matters to the extent supported by the state-of-the-art in terms of methods and data ....

Therefore, the Commission adopts the following policy statement regarding the expanded NRC use of PRA:

(1) The use of PRA technology should be increased in all regulatory matters to the extent supported by the state-of-the-art in PRA methods and data and in a manner that complements the NRC's deterministic approach and supports the NRC's traditional defense-in-depth philosophy.

(2) PRA and associated analyses (e.g., sensitivity studies, uncertainty analyses, and importance measures) should be used in regulatory matters, where practical within the bounds of the state-of-the-art, to reduce unnecessary conservatism associated with current regulatory requirements, regulatory guides, license commitments, and staff practices. Where appropriate, PRA should be used to support the proposal for additional regulatory requirements in accordance with 10 CFR 50.109 (Backfit Rule). Appropriate procedures for including PRA in the process for changing regulatory requirements should be developed and followed. It is, of course, understood that the intent of this policy is that existing rules and regulations shall be complied with unless these rules and regulations are revised.

(3) PRA evaluations in support of regulatory decisions should be as realistic as practicable and appropriate supporting data should be publicly available for review.

(4) The Commission's safety goals for nuclear power plants and subsidiary numerical objectives are to be used with appropriate consideration of uncertainties in making regulatory judgments on the need for proposing and backfitting new generic requirements on nuclear power plant licensees.

2.3 Applicable Regulations In 10 CFR 50.36, "Technical specifications," the NRC established its regulatory requirements related to the content of TSs. Pursuant to 10 CFR 50.36, TSs are required to include items in the following categories related to station operation: (1) safety limits, limiting safety system settings, and limiting control settings; (2) LCOs; (3) SRs; (4) design features; and (5) administrative controls. These categories will remain in the RBS TSs.

Paragraph 50.36(c)(3) of 10 CFR states, "[s]urveillance requirements 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 limiting

conditions for operation will be met." The FR notice published on July 6, 2009 (74 FR 31996),

which announced the availability of TSTF-425, Revision 3, states that the addition of the SFCP to the TSs provides the necessary administrative controls to require that SR frequencies relocated to the SFCP are conducted at a frequency 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. The FR notice also states that changes to SR frequencies in the SFCP would be made using the methodology contained in NEI 04-10, Revision 1, including qualitative considerations, results of risk analyses, sensitivity studies and any bounding analyses, and recommended monitoring of structures, systems, and components (SSCs), and are required to be documented.

Existing regulatory requirements, such as 10 CFR 50.65, "Requirements for monitoring the effectiveness of maintenance at nuclear power plants" (i.e., the Maintenance Rule), and 10 CFR Part 50, Appendix B, Criterion XVI, "Corrective Action," require licensee monitoring of surveillance test failures and implementing corrective actions to address such failures. Such failures can result in the licensee increasing the frequency of a surveillance test. In addition, if the TSs are amended to require that changes to the frequencies listed in the SFCP be made in accordance with NEI 04-10, Revision 1, the licensee would be required to monitor the performance of SSCs for which SR frequencies are decreased to assure reduced testing does not adversely impact the SSCs.

2.4 Applicable NRC Regulatory Guides and Review Plans Regulatory Guide (RG) 1.174, Revision 3, "An Approach for Using Probabilistic Risk Assessment in Risk-Informed Decisions on Plant-Specific Changes to the Licensing Basis" (Reference 9), describes an acceptable risk-informed approach for assessing the nature and impact of proposed permanent licensing basis changes by considering engineering issues and applying risk insights. This RG also provides risk acceptance guidelines for evaluating the results of such evaluations.

RG 1.177, Revision 1, "An Approach for Plant-Specific, Risk-Informed Decisionmaking:

Technical Specifications" (Reference 10), describes an acceptable risk-informed approach specifically for assessing proposed TS changes.

RG 1.200, Revision 2, "An Approach for Determining the Technical Adequacy of Probabilistic Risk Assessment Results for Risk-Informed Activities" (Reference 11 ), describes an acceptable approach for determining whether the quality of the PRA, in total or the parts that are used to support an application, is sufficient to provide confidence in the results, such that the PRA can be used in regulatory decisionmaking for light-water reactors (LWRs).

NUREG-0800, "Standard Review Plan [SRP] for the Review of Safety Analysis Reports for Nuclear Power Plants: LWR Edition," Chapter 19, Section 19.2, "Review of Risk Information Used to Support Permanent Plant-Specific Changes to the Licensing Basis: General Guidance" (Reference 12), provides general guidance for evaluating the technical basis for proposed risk-informed changes. Guidance on evaluating PRA technical adequacy is provided in SRP, Chapter 19, Section 19.1, Revision 3, "Determining the Technical Adequacy of Probabilistic Risk Assessment for Risk-Informed License Amendment Requests After Initial Fuel Load" (Reference 13). More specific guidance related to risk-informed TS changes is provided in SRP, Chapter 16, Section 16.1, Revision 1, "Risk-Informed Decision Making: Technical Specifications" (Reference 14), which includes changes to surveillance test intervals (STls) (i.e.,

surveillance frequencies) as part of risk-informed decisionmaking. Section 19.2 of the SRP

references the same criteria as RG 1.174, Revision 3, and RG 1.177, Revision 1, and states that a risk-informed application should be evaluated to ensure that the proposed changes meet the following key principles:

The proposed change meets the current regulations unless it is explicitly related to a requested exemption or rule change;

The proposed change is consistent with the defense-in-depth philosophy;

The proposed change maintains sufficient safety margins;

When proposed changes result in an increase in core damage frequency (CDF) or risk, the increases should be small and consistent with the intent of the Commission's Safety Goal Policy Statement;

The impact of the proposed change should be monitored using performance measurement strategies.

NUREG-1434, Revision 4, "Standard Technical Specifications, General Electric BWR [Boiling Water Reactor]/6 Plants," Volume 1, Specifications, and Volume 2, Bases (Reference 15),

contain the improved STS for General Electric BWR/6 plants. The improved STS were developed based on the criteria in the Final Commission Policy Statement of Technical Specifications Improvements for Nuclear Power Reactors, dated July 22, 1993 (58 FR 39132),

which was subsequently codified by changes to 10 CFR 50.36 (60 FR 36953). 1

3.0 TECHNICAL EVALUATION

The licensee's adoption of TSTF-425, Revision 3, would provide for relocation of applicable SR frequencies to the SFCP, would provide for the addition of the SFCP to the Administrative Controls section of TSs, and would require the application of NEI 04-10, Revision 1, for any changes to SR frequencies within the SFCP. The licensee's application for the changes proposed in TSTF-425, Revision 3, included documentation regarding technical adequacy of the PRA consistent with the requirements of RG 1.200, Revision 2. In accordance with NEI 04-10, Revision 1, PRA methods are used, in combination with plant performance data and other considerations, to identify and justify modifications to the surveillance frequencies of equipment at nuclear power plants. This is consistent with guidance provided in RG 1.174, Revision 3, and RG 1.177, Revision 1, in support of changes to STls.

3.1 Five Key Safety Principles The guidance in RG 1.177, Revision 1, outlines five key safety principles necessary for risk-informed changes to TSs. Each of these principles is addressed in NEI 04-10, Revision 1.

Section 3.1.1 through Section 3.1.5 of this SE discuss the five principles, including the NRC staffs evaluation of how the licensee's LAR satisfies each principle.

1 RBS converted to the standard TSs via amendment dated July 20, 1995 (ADAMS Accession No. ML021610732).

3.1.1 The Proposed Change Meets Current Regulations Paragraph 50.36(c)(3) of 10 CFR states that TSs will include surveillances which are "requirements relating to test, calibration, or inspection to assure that necessary quality of systems and components is maintained, that facility operation will be within safety limits, and that the limiting conditions for operation will be met." The licensee is required by its TSs to perform surveillance tests, calibration, or inspection on specific safety-related equipment (e.g.,

reactivity control, power distribution, electrical, and instrumentation) to verify system operability.

Surveillance frequencies are based primarily upon deterministic methods, such as engineering judgment, operating experience, and manufacturer's recommendations. The licensee's use of NRG-approved methodologies identified in NEI 04-10, Revision 1, provides a way to establish risk-informed surveillance frequencies that complements the deterministic approach and supports the NRC's traditional defense-in-depth philosophy.

The surveillances themselves would remain in the TSs as required by 10 CFR 50.36(c)(3), but the frequencies would be specified by references to the SFCP, which per proposed TS 5.5.12, must ensure that LCOs are met. This change is analogous to other NRG-approved TS changes in which the SRs are retained in the TSs, but the related surveillance frequencies are relocated to licensee-controlled documents, such as surveillances performed in accordance with the lnservice Testing Program (required by RBS TS 5.5.6) and the Primary Containment Leakage Rate Testing Program (required by RBS TS 5.5.13). Thus, this proposed change complies with 10 CFR 50.36(c)(3) by retaining the 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.

The requirements in 10 CFR 50.65 and 10 CFR Part 50, Appendix B, Criterion XVI, and the monitoring of surveillance test failures that would be required by NEI 04-10, Revision 1, per proposed TS 5.5.12, will ensure that surveillance frequencies are sufficient to satisfy 10 CFR 50.36(c)(3) requirements and that any test failures will be identified and corrective actions will be implemented to address such failures . The licensee's SFCP ensures that SRs specified in the TSs are performed at intervals sufficient to assure that the above regulatory requirements are met. Based on the above, the NRC staff concludes that the proposed change to relocate surveillance frequencies meets the first key safety principle of RG 1.177, Revision 1, by complying with the current regulations.

3.1.2 The Proposed Change Is Consistent With the Defense-in-Depth Philosophy The defense-in-depth philosophy (i.e., the second key safety principle of RG 1.177, Revision 1),

is maintained if:

A reasonable balance is preserved among prevention of core damage, prevention of containment failure, and consequence mitigation.

Over-reliance on programmatic activities to compensate for weaknesses in plant design is avoided.

System redundancy, independence, and diversity are preserved commensurate with the expected frequency, consequences of challenges to the system, and uncertainties (e.g., no risk outliers). Because the scope of the proposed methodology is limited to revision of surveillance frequencies, the redundancy, independence, and diversity of plant systems are not impacted.

Defenses against potential common cause failures are preserved, and the potential for the introduction of new common cause failure mechanisms is assessed.

Independence of barriers is not degraded.

Defenses against human errors are preserved.

The intent of the General Design Criteria in 10 CFR Part 50, Appendix A, is maintained.

The adoption of TSTF-425, Revision 3, includes the application of NEI 04-10, Revision 1, for any changes to surveillance frequencies within the SFCP. The guidance in NEI 04-10, Revision 1, uses both the CDF and the large early release frequency (LERF) metrics to evaluate the impact of proposed changes to surveillance frequencies. The guidance in RG 1.174, Revision 3, and RG 1.177, Revision 1, for changes to CDF and LERF, is achieved by evaluation using a comprehensive risk analysis, which assesses the impact of proposed changes, including contributions from human errors and common cause failures. Defense-in-depth is also included in the methodology explicitly as a qualitative consideration outside of the risk analysis, as is the potential impact on detection of component degradation that could lead to an increased likelihood of common cause failures. The NRC staff concludes that both the quantitative risk analysis and the qualitative considerations assure that a reasonable balance of defense-in-depth is maintained in order to ensure protection of public health and safety, satisfying the second key safety principle of RG 1.177, Revision 1.

3.1.3 The Proposed Change Maintains Sufficient Safety Margins To evaluate a change in the relocated surveillance frequency, the licensee will perform a probabilistic risk evaluation using the guidance contained in NRG-approved NEI 04-10, Revision 1, in accordance with the SFCP. The licensee states that the SFCP provides the necessary administrative controls to require that SRs related to testing, calibration and inspection are conducted at a frequency 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. The engineering evaluation that will be conducted by the licensee under the SFCP when frequencies are revised will assess the impact of the proposed frequency change to assure that sufficient safety margins are maintained. The guidelines used to make that assessment will include ensuring the proposed surveillance test frequency change is not in conflict with approved industry codes and standards nor does it adversely affect any assumptions or inputs to the safety analysis, or, if such inputs are affected, justification is provided to ensure sufficient safety margin will continue to exist.

The design, operation, testing methods, and acceptance criteria for 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 Updated Final Safety Analysis Report and the Bases to TSs), because 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. As a result, the NRC staff concludes that safety margins are maintained by the proposed methodology, and, therefore, the third key safety principle of RG 1.177 is satisfied.

3.1.4 When Proposed Changes Result in an increase in Core Damage Frequency or Risk, the Increases Should be Small and Consistent with the Intent of the Commission's Safety Goal Policy Statement The guidance in RG 1.177, Revision 1, provides a framework for evaluating the risk impact of future changes to the surveillance frequencies in the SFCP. The risk evaluation includes the identification of the risk contribution from impacted surveillances, determination of the risk impact from the change to the proposed surveillance frequency, and performance of sensitivity and uncertainty evaluations. The adoption of TSTF-425, Revision 3 (which is reflected in proposed TS 5.5.12), includes the application of NEI 04-10, Revision 1, to any changes to the frequencies listed in the SFCP. The guidance in NEI 04-10, Revision 1, satisfies the intent of RG 1.177, Revision 1, guidelines for evaluating the change in risk, and for assuring that such changes are small by providing the technical methodology to support risk-informed TS for control of surveillance frequencies.

3.1.4.1 PRA Technical Adequacy The technical adequacy of the licensee's PRA must be commensurate with the safety significance of the proposed TS change and the role the PRA plays in justifying the change.

That is, the higher the change in risk or the greater the uncertainty in that risk from the requested TS change, or both, the more rigor that must go into ensuring the quality of the PRA.

Consistent with the information provided in Regulatory Issue Summary (RIS) 2007-06, "Regulatory Guide 1.200 Implementation," dated March 22, 2007 (Reference 16), the NRC staff used RG 1.200, Revision 2, to assess the technical adequacy of the PRA used to support risk-informed applications received after March 2010.

The guidance in RG 1.200, Revision 2, provides for assessing the technical acceptability of a PRA. RG 1.200 endorses (with clarifications and qualifications) the use of the following:

1. American Society of Mechanical Engineers (ASME)/American Nuclear Society (ANS)

RA-Sa-2009, "Addenda to ASME RA-S-2008 Standard for Level 1/Large Early Release Frequency Probabilistic Risk Assessment for Nuclear Power Plant Applications" (i.e., the PRA Standard) (Reference 17);

2. NEI 00-02, "Probabilistic Risk Assessment (PRA) Peer Review Process Guidance" (Reference 18); and

3. NEI 05-04, "Process for Performing Internal Events PRA Peer Reviews Using the ASME/ANS PRA Standard," Revision 2 (Reference 19).

RG 1.200, Revision 1 endorsed the internal events PRA standard ASME RA-Sb-2005, "Addenda to ASME RA-S-2002 Standard for Probabilistic Risk Assessment for Nuclear Power Plant Applications."

The RBS PRA to support the SFCP used an internal events PRA model, which included internal flooding. Additionally, the licensee performed an assessment of the PRA models used to support the SFCP using the guidance of RG 1.200, Revision 2, to assure that the PRA models were technically acceptable for use in assessing the change in risk due to changes to surveillance frequencies of SSCs, using plant-specific data and models. The guidance in NEI 04-10, Revision 1, necessitates that the supporting requirements of the PRA standard meet

Capability Category II for the internal events PRA and any identified deficiencies to those supporting requirements be assessed further to determine any impacts of proposed decreases to surveillance frequencies, including the use of sensitivity studies where appropriate.

The licensee stated that the RBS internal events PRA model, Revision 5, underwent a full-scope peer review in April 2011. The Boiling Water Reactor Owners Group conducted the peer review and reviewed the PRA model against the ASME/ANS RA-Sa-2009 PRA standard as endorsed by RG 1.200, Revision 2. The licensee stated that it subsequently completed the RBS PRA model, Revision 6, which incorporated the resolutions to all of the significant Facts and Observations (F&Os) from the full-scope peer review, as well as a PRA upgrade incorporating updates to the internal flooding and LERF analyses. The licensee also stated that a focused-scope peer review of the PRA model (i.e., Revision 6 upgrade), for internal flooding and LERF, was conducted in September 2017 against the ASME/ANS RA-Sa-2009 PRA standard as endorsed by RG 1.200, Revision 2.

In Tables 1 and 2 of Attachment 2 to the LAR dated February 28, 2018 (Reference 1), the licensee provided a description and disposition of the F&Os from the 2011 and 2017 peer reviews, respectively. The NRC staff reviewed the summary of the peer review findings and the licensee's resolution or assessment of the impact of the use of the PRA to manage the SFCP.

The NRC staff determined whether any gaps in the PRA model were identified that could impact the use of the PRA and ensured that any identified gaps in meeting Capability Category II would be addressed in the SFCP by using the methodology in NEI 04-10, Revision 1, consistent with RG 1.200, Revision 2. For the F&Os described below, the licensee did not initially provide justification for concluding that the F&O had a minimal impact on the use of the PRA with respect to the changes to the surveillance frequencies in the SFCP or describe how the impact of the unresolved F&O would be evaluated. In response to NRC staff questions, the licensee provided additional information to address the F&Os.

By supplemental letter dated December 17, 2018 (Reference 4), the licensee provided updated resolutions and assessments. The 2017 focused-scope peer review team created F&O RB-6096, related to internal flooding Supporting Requirement IFSO-A4, which identified that no evaluation was performed to identify human-induced flooding mechanisms. In its letter dated December 17, 2018, the licensee stated that it reviewed the test and maintenance procedures for human-induced flooding mechanisms and identified that only vent and fill operations create an opening in a system. These openings are small and have a low associated flow rate. Therefore, the likelihood of a maintenance-induced flooding event of any significance is not significant. Based on the licensee's assessment of low likelihood of human induced flooding mechanisms, the NRC staff concludes that this F&O has a negligible impact on this use of the PRA for changes to the surveillance frequencies in the SFCP.

The 2017 focused-scope peer review team created F&O RB-6101, related to Supporting Requirement LE-F3, which identified that a review of key assumptions in the LERF analysis had not been performed. In its December 17, 2018 letter, the licensee clarified that the LERF analysis reviews the key model assumptions and the applicability against the generic sources of model uncertainty. The licensee explained that in order to ensure the selected sensitivity cases adequately address the uncertainty from key assumptions, those sources of uncertainty with the potential to challenge the acceptance criteria for candidate STI changes, would be evaluated with additional sensitivity studies during the TSTF-425, Revision 3, implementation in accordance with NEI 04-10, Revision 1. Because the licensee confirmed that the key assumptions in the LERF analysis will be reviewed in accordance with the NRC-approved

NEI 04-10, Revision 1, the NRC staff concludes that this F&O has no impact on the use of the PRA for changes to the surveillance frequencies in the SFCP.

The 2017 focused-scope peer review team created F&O RB-6106, related to internal flooding Supporting Requirement IFQU-A5, which identified that a consistency check of the internal flooding human error probabilities (HEPs) was not performed. In its letter dated December 17, 2018, the licensee stated that a consistency check was performed for the internal flooding HEPs and that the HEPs were reasonable and consistent with similar operator actions in the analysis, given the context of the scenarios and plant operational practices, procedures, and experience.

Because the licensee confirmed that it performed internal flooding HEP consistency evaluations and found the HEPs acceptable, the NRC staff concludes that this F&O has no impact on the proposed use of the PRA.

The 2017 focused-scope peer review team created F&O RB-6108, related to internal flooding Supporting Requirement IFQU-A7, which identified that the human failure events (HFE) values in the dependency analysis were not set (seeded) with sufficiently high values to ensure that cutsets with multiple HFEs were not truncated. In its letter dated December 17, 2018, the licensee explained that the HEPs for all operator actions were set to a sufficiently high value and that this F&O has no impact on the application. Based on the information provided, the NRC staff concludes that the licensee has addressed the seeding of HEPs for the dependency analysis appropriately for the proposed use of the PRA.

The 2017 focused-scope peer review team created F&O RB-6110, related to internal flooding Supporting Requirement IFQU-B3, which identified that a review of sources of modeling uncertainty in the internal flooding PRA and its impact on the results was not performed. In its letter dated December 17, 2018, the licensee stated that a review of key model assumptions as well as the generic sources of model uncertainty was performed consistent with the guidance in NUREG-1855, Revision 1, "Guidance on the Treatment of Uncertainties Associated with PRAs in Risk-Informed Decisionmaking," dated March 2017 (Reference 20). The licensee stated that the sources of uncertainty will be used to identify candidate sensitivity analyses and assess those uncertainties that may impact the internal flooding analysis results. Because the licensee confirmed that it reviewed the key assumptions in the LERF analysis and will use those results to address impacts to the internal flooding analysis results, the NRC staff concludes that this F&O has no impact on the proposed use of the PRA.

Based on the preceding analysis, the NRC staff concludes that the licensee addressed the findings from the peer reviews and demonstrated that they have no significant impact on the technical adequacy of the PRA. Therefore, the NRC staff concludes that the licensee has evaluated its internal events PRA against the current ASME/ANS RA-Sa-2009 PRA standard and RG 1.200, Revision 2, and that the internal events, including internal flooding PRA model, is of sufficient technical adequacy to support the evaluation of changes to TS surveillance frequencies that are relocated to the SFCP.

3.1.4.2 Scope of the PRA In accordance with NEI 04-10, Revision 1, the licensee should evaluate each proposed change to a relocated surveillance frequency to determine the change's potential impact on risk (CDF and LERF) from internal events, fires, seismic, other external events, and at shutdown conditions. In cases where a PRA of sufficient scope or quantitative risk models are unavailable, the licensee may use bounding analyses, or other conservative quantitative

evaluations. A qualitative screening analysis may be used when the surveillance frequency impact on plant risk is shown to be negligible or zero.

The licensee has full-power internal events and internal floods PRA models. These models received peer reviews as discussed in SE Section 3.1.4.1. As required by proposed TS 5.5.12 and in accordance with NEI 04-10, Revision 1, the licensee will use these models to perform quantitative evaluations to support the development of changes to surveillance frequencies in the SFCP.

RBS does not have PRA models for internal fires, seismic events, external flooding, high winds, and other external hazards (e.g. transportation, nearby facility accidents, etc.). As required by proposed TS 5.5.12 and in accordance with NEI 04-10, Revision 1, the licensee will perform an initial qualitative screening analysis, and, if the qualitative information is not sufficient to provide confidence that the net impact of the STI change would be negligible, a bounding analysis will be performed. In its letter dated December 17, 2018, the licensee stated that qualitative assessment of external hazards will assess available Individual Plant Examination of External Events information to determine the impact on proposed STI changes, consistent with Step 1Oa of the NEI 04-10 methodology. The licensee stated that insights may also be obtained from the fire safe shutdown analysis and risk management actions for managing fire risk. In addition, bounding analyses for STI changes will be performed in accordance with Step 1Ob of NEI 04-10, Revision 1.

Additionally, the licensee stated that the evaluation of fire risk and other external events risk supporting the SFCP will reflect and consider the current plant configuration and operating experience. The licensee states that for applicable STI change evaluations, qualitative evaluation of fire and external events risk in support of Step 1Ob would include consideration of applicability to the current plant configuration and operating experience. The licensee will document this information for each STI change provided to the Integrated Decision Panel.

Based on the above considerations, the NRC staff finds the licensee's treatment of external events acceptable. In addition, the staff concludes that through the application of NRG-approved NEI 04-10, Revision 1, per proposed TS 5.5.12, the licensee's evaluation methodology is sufficient to ensure the scope of the risk contribution of each surveillance frequency change is properly identified for evaluation, and is consistent with Regulatory Position 2.3.2, "Scope of the Probabilistic Risk Assessment for Technical Specification Change Evaluations," of RG 1.177, Revision 1.

3.1.4.3 PRA Modeling The LAR (Reference 1) states that its SFCP methodology includes a determination of whether the SSCs affected by a proposed change to a surveillance frequency are modeled in the PRA.

Where the SSC is directly or implicitly modeled, a quantitative evaluation of the risk impact may be carried out. The methodology adjusts the failure probability of the impacted SSCs, including any impacted common cause failure modes based on the proposed change to the surveillance frequency. Where the SSC is not modeled in the PRA, bounding analyses are performed to characterize the impact of the proposed change to the surveillance frequency. Potential impacts on the risk analyses due to screening criteria and truncation levels are addressed by the requirements for PRA technical adequacy, consistent with guidance contained in RG 1.200, Revision 2, and by sensitivity studies identified in NEI 04-10, Revision 1.

The NRC staff concludes that through the application of NRG-approved NEI 04-10, Revision 1, which would be required by proposed TS 5.5.12, the PRA modeling is sufficient to ensure an acceptable evaluation of risk for the proposed changes in surveillance frequency, and is consistent with Regulatory Position 2.3.3, "Probabilistic Risk Assessment Modeling," of RG 1.177, Revision 1.

3.1.4.4 Assumptions for Time Related Failure Contributions The failure probabilities of SSCs modeled in PRAs may include a standby time-related contribution and a cyclic demand-related contribution. The adjustment criteria in NEI 04-10, Revision 1, adjust the time-related failure contribution of SSCs affected by the proposed change to a surveillance frequency. This is consistent with RG 1.177, Revision 1, Section 2.3.3, which permits separation of the failure rate contributions into demand and standby for evaluation of surveillance requirements. In addition, the process described by NEI 04-10, Revision 1, which would be imposed by TS 5.5.12, includes consideration of qualitative sources of information with regard to potential impacts of test frequency on SSC performance, including industry and plant-specific operating experience, vendor recommendations, industry standards, and code-specified test intervals. Thus, the NRC staff concludes that risk analyses and other information will be used.

The NRC staff concludes that through the application of NRG-approved NEI 04-10, Revision 1, the licensee will employ reasonable assumptions with regard to any extensions of STI, and is consistent with Regulatory Position 2.3.4, "Assumptions in Completion Time and Surveillance Frequency Evaluations," of RG 1.177, Revision 1.

3.1.4.5 Sensitivity and Uncertainty Analyses Proposed TS 5.5.12 would require that changes to frequencies listed in the SFCP be made in accordance with NEI 04-10, Revision 1. Therefore, the licensee would be required to use sensitivity studies to assess the impact of uncertainties from key assumptions of the licensee's PRA, uncertainty in the failure probabilities of the affected SSCs, impact on the frequency of initiating events, and any identified deviations from Capability Category II of the ASME/ANS RA-Sa-2009 PRA standard. Where the sensitivity analyses identify a potential impact on the proposed change, revised surveillance frequencies are considered, along with any qualitative considerations that may bear on the results of such sensitivity studies. The licensee would also perform necessary monitoring and feedback of SSC performance once the revised surveillance frequencies are implemented. Thus, through the application of NRG-approved NEI 04-10, Revision 1, the licensee will appropriately consider the possible impact of PRA model uncertainty and sensitivity to key assumptions and model limitations, consistent with Regulatory Position 2.3.5, "Sensitivity and Uncertainty Analyses Relating to Assumptions in Technical Specification Change Evaluations," of RG 1.177, Revision 1.

3.1.4.6 Acceptance Guidelines In accordance with the proposed TS 5.5.12, under its SFCP the licensee would quantitatively evaluate the change in total risk (including internal and external events contributions) in terms of CDF and LERF using the guidance contained in NRG-approved NEI 04-10, Revision 1. The qualitative evaluation will include both the individual risk impact of a proposed change in surveillance frequency, and the cumulative impact from all individual changes to surveillance frequencies. In accordance with the acceptance criteria in RG 1.174, Revision 3, for very small changes in risk, each individual change to surveillance frequency must show a risk increase

below 1E-6 per year for CDF, and below 1E-7 per year for LERF or the process terminates without permitting the proposed changes. Where quantitative results are unavailable for comparison with the acceptance guidelines, appropriate qualitative analyses are used to demonstrate that the associated risk impact of a proposed change to surveillance frequency is negligible. Otherwise, bounding quantitative analyses are used to demonstrate the risk impact is at least one order of magnitude lower than the acceptance criteria in RG 1.174 for very small changes in risk. In addition to assessing each individual SSC surveillance frequency change, the proposed SFCP would ensure that cumulative impact of all changes result in a risk increase less than 1E-5 per year for CDF, and less than 1E-6 per year for LERF. Further, proposed TS 5.5.12 would ensure that the total CDF and total LERF must be reasonably shown to be less than 1E-4 per year and 1E-5 per year, respectively. The NRC staff finds that these values are consistent with the acceptance criteria of RG 1.174, Revision 3, as referenced by RG 1.177, Revision 1, for changes to surveillance frequencies.

Consistent with the NRC safety evaluation dated September 19, 2007, on NEI 04-10, Revision 1, proposed TS 5.5.12 will require the licensee to calculate the total change in risk (i.e.,

the cumulative risk) by comparing a baseline model that uses failure probabilities based on surveillance frequencies prior to being changed per the SFCP to a revised model that uses failure probabilities based on the changed surveillance frequencies. The staff further notes that NEI 04-10, Revision 1, includes a provision to exclude the contribution to cumulative risk from individual changes to surveillance frequencies associated with insignificant risk increases (i.e.,

less than 5E-8 CDF and 5E-9 LERF) once the baseline PRA models are updated to include the effects of the revised surveillance frequencies.

The quantitative acceptance guidance of RG 1.174, Revision 3, is supplemented by qualitative information to evaluate the proposed changes to surveillance frequencies, including industry and plant-specific operating experience, vendor recommendations, and industry standards, or at least bounding, quantitative results of sensitivity studies and SSC performance data and test history. The final acceptability of the proposed change is based on all of these considerations and not solely on the PRA results. Post-implementation performance monitoring and feedback are also required to assure continued reliability of the SSC's. The licensee's application of NEI 04-10 provides acceptable methods for evaluating the risk increase associated with proposed changes to surveillance frequencies, consistent with Regulatory Position 2.4, "Acceptance Guidelines for Technical Specification Changes," of RG 1.177, Revision 1.

Therefore, the NRC staff finds that the licensee's proposed methodology satisfies the fourth key safety principle of RG 1.177, Revision 1, by assuring any increase in risk is small consistent with the intent of the Commission's Safety Goal Policy Statement.

3.1.5 The Impact of the Proposed Change Should Be Monitored Using Performance Measurement Strategies The licensee's proposed TS 5.5.12 requires the application of NEI 04-10, Revision 1, in the SFCP. The guidance in NEI 04-10 includes performance monitoring of SSCs whose surveillance frequencies have been revised as part of a feedback process to assure that any change in test frequency has not resulted in degradation of equipment performance and operational safety. The monitoring and feedback includes consideration of monitoring of equipment performance required by the Maintenance Rule (10 CFR 50.65). In the event of degradation of SSC performance, the surveillance frequency will be reassessed in accordance with the methodology, in addition to any corrective actions that may apply as part of the maintenance rule requirements. The performance monitoring and feedback specified in NEI 04-10, Revision 1, is sufficient to assure acceptable SSC performance and is consistent

with Regulatory Position 3.2, "Maintenance Rule Control," of RG 1.177, Revision 1. Thus, the NRC staff concludes that the fifth key safety principle of RG 1.177, Revision 1, is satisfied.

3.2 Limitations and Conditions The NRC staff's SE in response to NEI 04-10, Section 4.0, states that:

The NRC staff finds that the methodology in NEI 04-10, Revision 1 is acceptable for referencing by licensees proposing to amend their TSs to establish a SFCP provided the following conditions are satisfied:

1. The licensee submits documentation with regards to PRA technical adequacy consistent with the requirements of RG 1.200, Section 4.2.

2. When a licensee proposes to use PRA models for which NRG-endorsed standards do not exist, the licensee submits documentation which identifies the quality characteristics of those models, consistent with RG 1.200 Sections 1.2 and 1.3. Otherwise, the licensee identifies and justifies the methods to be applied for assessing the risk contribution for those sources of risk not addressed by PRA models.

Section 3.1.4.1 of this SE discusses the technical adequacy of the licensee's PRA model and finds it to be consistent with NRG-endorsed guidance. As discussed in Section 3.1.4.1 the NRC staff finds the information supplied in the LAR, as supplemented, supports the licensee's proposed PRA and therefore the limitations in the NRC staff's SE related to NEI 04-10 have been met.

3.3 Addition of Surveillance Frequency Control Program to Administrative Controls The licensee proposed to include the SFCP and specific requirements into the RBS TS 5.5.12, as follows:

Surveillance Frequency Control Program This program provides controls for Surveillance Frequencies. The program shall ensure that Surveillance Requirements specified in the Technical Specifications are performed at intervals sufficient to assure the associated Limiting Conditions for Operation are met.

a. The Surveillance Frequency Control Program shall contain a list of Frequencies of those Surveillance Requirements for which the Frequency is controlled by the program.

b. Changes to the Frequencies listed in the Surveillance Frequency Control Program shall be made in accordance with NEI 04-10, "Risk-Informed Method for Control of Surveillance Frequencies," Revision 1.

c. The provisions of Surveillance Requirements 3.0.2 and 3.0.3 are applicable to the Frequencies established in the Surveillance Frequency Control Program.

Based on its review in the sections above, the NRC staff concludes that the SFCP is an acceptable program to list surveillance frequencies and control changes to surveillance frequencies. The staff further finds that proposed TS 5.5.12 includes the necessary program and applicability requirements, that those requirements are consistent with the TSTF-425, Revision 3, and that those requirements will ensure that LCOs are met. Therefore, the NRC staff finds proposed TS 5.5.12 acceptable.

3.4 Deviations from TSTF-425 and Other Changes 3.4.1 Definition of Staggered Test Basis The definition of STAGGERED TEST BASIS is being retained in the RBS TSs due to its continued use in several SR frequencies, which are not the subject of this LAR (e.g.,

SRs 3.4.4.3, 3.5.1.7, and 3.6.1.6.1 ). This is an administrative deviation and the NRC staff concludes that the definition should be retained to inform the SRs that use the definition and that remain the TS. Therefore, the staff finds this deviation acceptable.

3.4.2 Variation in TS Surveillance Requirement Numbering The RBS SRs numbering differs from the corresponding TSTF-425 SRs. The NRC staff finds that the SR numbering variations are editorial and non-substantive deviations from TSTF-425 that are consistent with the TS numbering scheme at RBS. Therefore, the NRC staff concludes that these deviations are acceptable.

3.4.3 Comparison of SR Changes between the RBS TSs and NUREG-1434 TSs The licensee stated that NUREG-1434 contains SRs that are not in the RBS TSs. The NRC staff reviewed the variations from the STSs in NUREG-1434 and determined that, because the omitted SRs were previously found to be inapplicable to RBS when it converted to the STSs, these deviations are consistent with currently approved RBS TSs. Therefore, the staff finds these variations acceptable.

The licensee stated that plant-specific SRs are not included in TSTF-425. These SRs were added to the RBS TSs per Amendment No. 188 (Reference 21), which implements TSTF-523, Revision 2, "Generic Letter 2008-01, Managing Gas Accumulation." TSTF-523 allows the option of relocating the applicable SRs to the Surveillance Frequency Control Program (SFCP).

The licensee stated that the RBS plant-specific SRs involve fixed periodic frequencies and do not meet any of the four exclusion criteria of TSTF-425. The NRC staff reviewed the proposed plant-specific SRs listed in Section 2.2 of the LAR and concludes that relocation of the plant-specific SR frequencies is consistent with TSTF-425, and the plant-specific SRs do not meet any of the exclusions identified in Section 1.0, "Introduction," of the NRC staff's model SE dated July 6, 2009. Therefore, the staff finds these variations acceptable.

The licensee proposed to add the SFCP to TS Section 5.5.12 instead of adding the program to the end of TS Section 5.5, as indicated in the NRC staff's model SE dated July 6, 2009.

Additionally, the licensee would remove the word "deleted" currently in TS Section 5.5.12. This change requires formatting changes that move applicable portions of the text as identified in the licensee's markup of the TS pages. The licensee considers the deviations to be administrative deviations from TSTF-425, Revision 3, that do not affect the substantive conclusions in the NRC's model SE dated July 6, 2009. The NRC staff evaluated the deviations and determined

that differences from TSTF-425 are not substantive and do not affect the acceptability of the SFCP. Therefore, the NRC staff finds these deviations to be acceptable.

3.4.4 Control Room Envelope Habitability Program The licensee proposed to revise TS 5.5.14.d as follows (deleted text in strikeout and added text in italics):

Measurement, at designated locations, of the CRE pressure ... by one subsystem of the CRFA [Control Room Fresh Air] System ... at a Frequency of 24 months on a STAGGERED TEST BASIS in accordance with the Surveillance Frequency Control Program. The results shall be trended and used as part of the 24 month assessment of the CRE [control room envelope] boundary assessment specified in 5.5.14.c (ii).

The licensee adopted TSTF-448, "Control Room Habitability," in Amendment No. 154 (Reference 22), which revised the SRs to perform control room envelope unfiltered air leakage testing in accordance with the Control Room Envelope Habitability Program. The licensee designated the Control Room Envelope Habitability Program as TS 5.5.14 and the subject SR as TS 5.5.14.d. The SR revised under TSTF-448 for Standard Technical Specifications (under NUREG-1434) was designated as SR 3.7.3.4. TSTF-425 includes relocation of the frequency for SR 3.7.3.4 to the SFCP. The licensee proposed to adopt the frequency change identified for NUREG-1434 SR 3.7.3.4 for RBS as TS 5.5.14.d.

The NRC staff reviewed the proposed changes and determined that reflecting the relocation of the SR frequency in STS SR 3.7.3.4 in TSTF-425, by modifying RBS TS 5.5.14.d continues to require that the CRE unfiltered air leakage testing specified in SR 5.5.14.d is performed as required by the Control Room Envelope Habitability Program. Also, the frequency currently referenced in TS 5.5.14.d is a periodic frequency that does not meet the exclusion criteria in TSTF-425, and relocation of the frequency is consistent with the intent of TSTF-425, Revision 3.

Therefore, the NRC staff finds the proposed changes to TS 5.5.14.d acceptable.

3.4.5 Administrative Control Programs SR Frequencies The licensee proposed changes to SR frequencies in TS 5.5. 7, "Ventilation Filter Testing Program (VFTP)," and TS 5.5.9, "Diesel Fuel Oil Testing Program," related to total particulate concentration of the fuel oil in the storage tanks that are not identified for relocation in TSTF-425, Revision 3 because they are plant-specific TSs. The changes would replace the specific frequency requirements in this TSs with "in accordance with the Surveillance Frequency Control Program." The staff reviewed the licensee's proposed changes to relocate these SRs and determined that the SR frequencies do not meet the exclusion criteria of TSTF-425, Revision 3, that the frequencies are fixed periodic frequencies, and that relocation of these frequencies is consistent with the intent of this TSTF. Therefore, the NRC staff finds that relocation of these plant-specific TS SR frequencies to the SFCP is acceptable.

3.4.6 Combined Unit Power Supplies SR The licensee proposed to revise SR 3.8.1.8 to correct a formatting error. Currently, SR 3.8.1.8.a and SR 3.8.1.8.b are listed within the same SR row, each with a frequency specified as 24 months. The proposed amendment would modify SR 3.8.1.8 to combine the

two SRs into a single SR with two sub-activities and one frequency (i.e., in accordance with the SFCP). The licensee proposed the following changes to SR 3.8.1.8:

Verify, for required unit power supplies:

a. Manual transfer of unit power supply from the normal offsite circuit to required alternate offsite circuit; and

b. Automatic transfer of bus E22-S004 through NNS-SWG1A or NNS-SWG1 B from the 22 kV onsite circuit to required offsite circuit.

The NRC staff reviewed the proposed changes to SR 3.8.1.8 and determined that combining SR 3.8.1.8.a and b. to share one frequency is consistent with the current SR and will ensure that the 10 CFR 50.36(c)(3) requirement that the TSs include requirements relating to test, calibration or inspection to assure that the necessary quality of systems and components is maintained, that the facility operation will be within safety limits and the limiting conditions for operation will be met. . Further, this change is consistent with the formatting of similar SRs in the RBS TS (e.g., SRs 3.8.1.7, 3.8.1.11, and 3.8.1.12) and would improve the readability of the TSs by using consistent formatting. Therefore, the NRC staff finds these changes acceptable.

3.4. 7 Repagination of TS Pages Due to the relocation and modification of SR frequencies, there were multiple SRs that moved to the next page. The licensee proposed the following changes:

Add pages 3.3-6a, 3.3-52a, 3.5-5a, 5.0-16b;

Replace current page 3.8-16 with new page 3.8-16 to accommodate the SRs that move to the next page;

Delete from current page 3.8-16 the text, "Table 3.8.1-1 has been deleted";

Delete rows for SRs 3.6A.1. 7 and 3.8.3.6 because the associated SRs were deleted; and

Minor formatting corrections.

The NRC staff reviewed the proposed changes and determined that the formatting and pagination changes identified in the markup of the TS pages are minor deviations from TSTF-425, are consistent with existing RBS TSs, and do not affect the acceptability of the SFCP and relocation of SR frequencies as evaluated in the NRC's model SE dated July 6, 2009. Therefore, the NRC staff finds the proposed changes acceptable.

3.5 Summary and Conclusions The NRC staff reviewed the licensee's proposed relocation of certain surveillance frequencies to a licensee-controlled document, proposal to control changes to surveillance frequencies in accordance with a new program, the SFCP, which is required by TS 5.5.12. The NRC staff confirmed that this amendment adheres to the TSTF-425 exclusion criteria in that it does not relocate surveillance frequencies that are specified by other approved programs, are purely

event-driven, are event-driven but have a time component for performing the surveillance on a one-time basis once the event occurs, or are related to specific conditions.

The proposed adoption of TS changes consistent with TSTF-425, Revision 3, and the risk-informed methodology of NRG-approved NEI 04-10, Revision 1, as referenced in TS 5.5.12 of the Administrative Controls section of the RBS TSs, satisfies the key principles of risk-informed decision making as delineated in RG 1.177, Revision 1 and RG 1.174, Revision 3 in that:

The proposed changes meet current regulations;

The proposed changes are consistent with defense-in-depth philosophy;

The proposed changes maintain sufficient safety margins;

Increases in risk resulting from the proposed changes are small and consistent with the Commission's Safety Goal Policy Statement; and

The impact of proposed change will be monitored with performance measurement strategies.

The proposed adoption of TS changes in TS Sections 3 and 5 are consistent with TSTF-425, Revision 3, and the use of NEI 04-01, as required by proposed TS 5.5.12, also meets the limitations and conditions in the NRC staff's SE on NEI 04-10.

Section 50.36(c) of 10 CFR specifies the categories that must be included in the TSs.

Section 50.36(c)(3) states, Surveillance requirements 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 limiting conditions for operation will be met.

Based on the above evaluation, the NRC staff concludes that, the proposed relocation of surveillance frequencies to a licensee-controlled document, the SFCP, which is controlled by the TS 5.5.12 requirement that the program ensure surveillance frequencies assure that LCOs are met and any changes to those frequencies are appropriate under NEI 04-10, the licensee continues to meet the requirements in 10 CFR 50.36( c)(3).

4.0 STATE CONSULTATION

In accordance with the Commission's regulations, the Louisiana State official was notified of the proposed issuance of the amendment on March 6, 2019. The State official had no comments.

5.0 ENVIRONMENTAL CONSIDERATION

This amendment changes a requirement with respect to installation or use of facility components located within the restricted area as defined in 10 CFR Part 20 and involves changes to SRs. The NRC staff has determined that the amendment involves no significant increase in the amounts, and no significant change in the types, of any effluents that may be

released offsite, and that there is no significant increase in individual or cumulative occupational radiation exposure. The Commission has previously issued a proposed finding that the amendment involves no significant hazards consideration published in the Federal Register on May 22, 2018 (83 FR 23733), and there has been no public comment on such finding. The amendment also changes a recordkeeping, reporting or administrative procedures or requirements and makes editorial or other minor corrective changes. Accordingly, this amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9) and ( c)( 10 ). Pursuant to 10 CFR 51.22(b ), no environmental impact statement or environmental assessment need be prepared in connection with the issuance of this amendment.

6.0 CONCLUSION

The Commission has concluded, based on the considerations discussed above, that: (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) there is reasonable assurance that such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.
