INC. WATERFORD STEAM ELECTRIC STATION. UNIT 3 DOCKET NO. 50-382

1.0 INTRODUCTION

By letter dated June 17, 2015 (Reference 1), as supplemented by letters dated March 3, 2016 (Reference 2), April 28, 2016 (Reference 3), and July 12, 2016 (Reference 21 ), Entergy Operations, Inc. (the licensee), submitted a license amendment request (LAR) which proposed changes to the Technical Specifications (TSs) for Waterford Steam Electric Station, Unit 3 (Waterford 3), which are contained in Appendix A of Renewed Facility Operating License No. NPF-38. The licensee requested to revise the Waterford 3 TSs by relocating specific surveillance requirement (SR) frequencies to a licensee-controlled program. The licensee requested to revise the TSs to require that changes to such surveillance frequencies will be made in accordance with Nuclear Energy Institute (NEI) 04-10, "Risk-Informed Technical Specifications Initiative Sb, Risk-Informed Method for Control of Surveillance Frequencies," Revision 1, dated April 2007 (Reference 4). The requested change is the adoption of U.S. Nuclear Regulatory Commission (NRC)-approved Technical Specification 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 5). The Federal Register (FR) notice published on July 6, 2009 (74 FR 31996), announced the availability of TSTF-425, Revision 3. By letter dated January 22, 2016 (Reference 6), the NRC sent a request for additional information (RAI) to the licensee.

By letter dated March 3, 2016, the licensee responded to this request. As a consequence of this response, the NRC staff sent another RAI by letter dated April, 12, 2016 (Reference 7). By letter dated April 28, 2016, the licensee responded to this second request. By letter dated July 12, 2016, the licensee provided a supplement proposing minor edits to the Technical Specifications.

The supplements from the licensee dated March 3, 2016, April 28, 2016, and July 12, 2016, provided additional information that clarified the application, did not expand the scope of the application as originally noticed, and did not change Enclosure 2 the NRC staff's original proposed no significant hazards consideration (NSHC) determination as published in the Federal Register on September 1, 2015 (80 FR 52805).

2.0 REGULATORY EVALUATION

2.1 Description of the Proposed Changes The licensee proposed to modify the Waterford 3 TSs by relocating specific surveillance frequencies to a licensee-controlled program (i.e., the Surveillance Frequency Control Program (SFCP)) in accordance with NEI 04-10, Revision 1. The licensee .stated that the proposed change is consistent with the adoption of NRG-approved TSTF-425, Revision 3. When implemented, TSTF-425, Revision 3, relocates most periodic frequencies of TS surveillances to the SFCP, and provides requirements for the new program in the Administrative Controls sections 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 2:: [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 an SR (e.g., "drywell to suppression chamber differential pressure decrease").

The SFCP describes the requirements for the program to control changes to the relocated surveillance frequencies.

The licensee proposed to add the SFCP to Section 6.0, "Administrative Controls," of the Waterford 3 TSs. The TS Bases for each affected surveillance would be revised to state that the frequency is controlled under the SFCP. The current information in the TS Bases will be relocated to the licensee-controlled SFCP. The proposed changes to the Administrative Controls sections of the TSs to incorporate the SFCP include a specific reference to NEI 04-10, Revision 1, as the basis for making any changes to the surveillance frequencies once they are relocated out of the TSs. By letter dated September 19, 2007 (Reference 8), the NRC staff approved Topical Report NEI 04-10, Revision 1, as acceptable for referencing in licensing actions to the extent specified and under the limitations delineated in NEI 04-10, Revision 1, and the safety evaluation (SE) providing the basis for NRC acceptance of NEI 04-10, Revision 1. For Waterford 3, the licensee proposed other changes and deviations from TSTF-425, which are discussed in Section 3.3 of this SE. 2.2 Applicable Commission Policy Statements In the "Final Policy Statement:

Technical Specifications for Nuclear Power Plants," 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 STSs. In this 1993 publication, the NRC states, in part: 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) 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 for 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 five specific categories related to station operation:

(1) safety limits, limiting safety system settings, and limiting control settings; (2) limiting conditions for operation; (3) SRs; (4) design features; and (5) administrative controls.

Items in these categories will remain in the Waterford 3 TSs. Section 50.36(c)(3) of 10 CFR 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." 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 surveillance 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 limiting conditions for operation will be met. The FR notice also states that changes to surveillance frequencies in the SFCP are made using the methodology contained in NEI 04-10, Revision 1, as approved by NRC staff, 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, by specifying that the TSs require that changes to the frequencies listed in the SFCP be made in accordance with NEI 04-10, Revision 1, the licensee will be required to monitor the performance of SSCs for which surveillance 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) 1.17 4, "An Approach for Using Probabilistic Risk Assessment in Risk-Informed Decisions on Plant-Specific Changes to the Licensing Basis, Revision 2 (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 regulatory guide also provides risk acceptance guidelines for evaluating the results of such evaluations.

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

Technical Specifications,

Revision 1 (Reference 10), describes an acceptable risk-informed approach specifically for assessing proposed TS changes. RG 1.200, "An Approach for Determining the Technical Adequacy of Probabilistic Risk Assessment Results for Risk-Informed Activities,

Revision 2 (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 LWRs. General guidance for evaluating the technical basis for proposed risk-informed changes is provided in 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). Guidance on evaluating PRA technical adequacy is provided in SRP, Chapter 19, Section 19.1, "Determining the Technical Adequacy of Probabilistic Risk Assessment for Risk-Informed License Amendment Requests After Initial Fuel Load," Revision 3 (Reference 13). More specific guidance related to risk-informed TS changes is provided in SRP, Chapter 16, Section 16.1, "Risk-Informed Decisionmaking:

Technical Specifications," Revision 1 (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 1.177, Revision 1, and RG 1.17 4, Revision 2, 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 explicitly relates 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 increase(s) 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.

3.0 TECHNICAL EVALUATION The licensee's adoption of TSTF-425, Revision 3, provides for administrative relocation of applicable surveillance frequencies, and provides for the addition of the SFCP to the Administrative Controls sections of TSs. The changes to the Administrative Controls section of the TSs will also require the application of NEI 04-10, Revision 1, as approved by the NRC, for any changes to surveillance frequencies within the SFCP. The licensee's application for the changes described in TSTF-425, Revision 3, included documentation regarding the PRA technical adequacy consistent with RG 1.200, Revision 2 (Reference 11 ). NEI 04-10, Revision 1, states, in part, that PRA methods are used 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 1.17 4, Revision 2 (Reference 9), and RG 1.177, Revision 1 (Reference 10), in support of changes to STls. 3.1 Review Methodology RG 1.177, Revision 1, identifies five key safety principles required for risk-informed changes to TSs. Each of these principles is addressed by NEI 04-10, Revision 1. 3.1.1 The Proposed Change Meets Current Regulations Unless it is Explicitly Related to a Requested Exemption or Rule Change Section 50.36(c)(3) of 10 CFR requires that TSs 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 approved methodologies identified in NEI 04-10, Revision 1, provides a way to establish informed surveillance frequencies that complements the deterministic approach and supports the NRC's traditional defense-in-depth philosophy.

The SRs themselves are remaining in the TSs, as required by 10 CFR 50.36(c)(3).

This change is analogous with other NRG-approved TS changes in which the SRs are retained in TSs, but the related surveillance frequencies are relocated to licensee-controlled documents, such as surveillances performed in accordance with the lnservice Testing Program and the Primary Containment Leakage Rate Testing Program. 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 limiting conditions for operation will be met. The regulatory requirements in 10 CFR 50.65 and 10 CFR Part 50, Appendix B, and the monitoring required by NEI 04-10, Revision 1, ensure that surveillance frequencies are sufficient to assure that the requirements of 10 CFR 50.36 are satisfied and that any performance deficiencies will be identified and appropriate corrective actions taken. The licensee's SFCP ensures that SRs specified in the TSs are performed at intervals sufficient to assure the above regulatory requirements are met. In light of the above, the NRC staff concludes that the proposed change meets the first key safety principle of RG 1.177, Revision 1 (Reference 10), by complying with 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 (CCFs) are preserved, and the potential for the introduction of new CCF 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 changes to the Administrative Controls section of the TSs will require the application of NEI 04-10, Revision 1, for any changes to surveillance frequencies within the SFCP. 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 of RG 1.174, Revision 2 (Reference 9), and RG 1.177, Revision 1(Reference10), 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 CCFs. 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 CCFs. 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 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 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 for making that assessment will include ensuring the proposed surveillance test frequency change is not in conflict with approved industry codes and standards or adversely affects 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 plants' licensing bases, including the Updated Final Safety Analysis Report and TS Bases, 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. On this basis, the NRC staff concludes that safety margins are maintained by the proposed methodology, and the third key safety principle of RG 1.177, Revision 1, is satisfied. 3.1.4 When Proposed Changes Result in an Increase in CDF or Risk, the Increases Should Be Small and Consistent with the Intent of the Commission's Safety Goal Policy Statement RG 1.177, Revision 1, provides a framework for evaluating the risk impact of proposed changes to surveillance frequencies which requires 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 changes to the Administrative Controls section of the TSs will require application of NEI 04-10, Revision 1, in the SFCP. NEI 04-10, Revision 1, satisfies the intent of RG 1.177, Revision 1, guidance for evaluation of the change in risk, and for assuring that such changes are small by providing the technical methodology to support risk-informed TSs for control of surveillance frequencies.

3.1.4.1 Quality of the PRA The quality 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 greater the change in risk or the greater the uncertainty in that risk from the requested TS change, or both, the more rigor that must be employed when ensuring the quality of the PRA. RG 1.200 (Reference

11) provides regulatory guidance for assessing the technical adequacy of a PRA. The current revision (i.e., Revision 2) of this RG endorses, with clarifications and qualifications, the use of (1) American Society of Mechanical Engineers (ASME)/American Nuclear Society (ANS) Standard, 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 15), (2) NEI 00-02, "Probabilistic Risk Assessment (PRA) Peer Review Process Guidance," Revision 1 (Reference 16), and (3) NEI 05-04, "Process for Performing Internal Events PRA Peer Reviews Using the ASME/ANS PRA Standard," Revision 2 (Reference 17). The licensee has performed an assessment of the PRA models used to support the SFCP using the guidance of RG 1.200, Revision 2 (with the exception of the shutdown PRA model for which an NRG-endorsed PRA standard does not exist), to assure that the PRA models are capable of determining the change in risk due to changes to surveillance frequencies of SSCs, using plant-specific data and models. Capability Category (CC) II of the NRG-endorsed PRA standard is the target capability level for supporting requirements for the internal events PRA for this application.

Any identified deficiencies to those requirements are assessed further to determine any impacts to proposed decreases to surveillance frequencies, including the use of sensitivity studies where appropriate, in accordance with NEI 04-10, Revision 1. A full-scope peer review by the Westinghouse Owners Group of the Waterford 3 internal events PRA was performed in August 2009 using RG 1.200, Revision 1 and PRA standard ASME/ANS RA-Sb-2005, "Standard for Probabilistic Risk Assessment for Nuclear Power Plant Applications, Addendum B to ASME RA-S-2002" (Reference 18). The licensee performed a self-assessment of the internal events PRA in 2013 using RG 1.200, Revision 2 and ASME/ANS RA-Sa-2009, "Addenda to ASME/ANS RA-S-2008, Standard for Level 1 /Large Early Release Frequency Probabilistic Risk Assessment for Nuclear Power Plant Applications," dated Februrary 2, 2009. The LAR Attachment 2, Table 3-1, "Status of Identified Gaps to Capability Category II of the ASME PRA Standard" (Reference 1), identifies PRA standard Supporting Requirements determined by the self-assessment not to meet CC II and provides an assessment of the impact of these findings (referred to in the LAR as "gaps") for this application.

The LAR explains that the impact of each "gap" will be reviewed as part of STI change evaluations.

Though not provided in this LAR, the facts and observations (F&Os) or findings from the 2009 full-scope internal events PRA peer review were provided in the Waterford 3 National Fire Protection Association (NFPA) 805 transition report LAR dated November 17, 2011 (Reference 19), along with dispositions for that application.

The Waterford 3 NFPA 805 LAR also provided findings from the November 2010 full-scope peer review and 2012 and 2013 followup focused-scoped peer reviews, along with their dispositions.

The NRC staff reviewed the self-assessment findings for the internal events PRA, the 2009 full-scope peer review findings on the internal events PRA, and the 2010, 2012, and 2013 full-scope and focused-scope peer review findings for the fire PRA as provided in the Waterford 3 NFPA 805 LAR. The NRC staff assessed these "gaps" and findings to identify whether any incompleteness could impact this application and to ensure any deficiencies in meeting CC II can be addressed for the SFCP per the NEI 04-10, Revision 1 methodology.

The NRC staff noted several self-assessment findings identified in LAR Attachment 2, Table 3-1 (Reference 1 ), associated with the internal flooding PRA that are dispositioned as having little or no impact on STI evaluations without explanation of this determination.

The NRC staff requested further information in RAl-1, submitted by letter dated January 22, 2016 (Reference 6), about "gaps" that appeared to represent incompleteness in the internal flooding PRA modelling.

In RAl-1.A (Reference 6), associated with Gap #1, the NRC staff noted that even though pipe break flooding sources were conservatively treated, exclusion of other flooding sources could result in underestimation of internal flooding risk and impact STI evaluations.

The NRC staff, therefore, requested justification of excluding flooding sources. In response to RAl-1.A by letter dated March 3, 2016 (Reference 2), the licensee explained that "non-pipe break" flooding sources were considered in the internal flooding PRA (IFPRA) and cited examples of flooding caused by failures of valves, tanks, heat exchangers, pumps, seals, gaskets, and fitting. The licensee, however, also explained that human-induced flooding events were screened from the analysis because in such cases there would be a heightened awareness that would facilitate immediate recovery of the event. The licensee concluded that "there is no underestimation of flood frequencies." The NRC staff notes that PRA standard Supporting Requirements IFSO-A4 and IFS0-82 appear to be met because the criteria for screening the excluded flooding sources are documented.

The NRC staff also notes that the internal flooding CDF and LERF reported in the licensee's response to NFPA 805 RAI dated May 14, 2015 (Reference 20), is low (i.e., 2.5E-06 and 8.6E-08, respectively).

The NRC staff observes that a small increase in internal CDF and LERF values resulting from inclusion of excluded flooding sources would be well below the RG 1.17 4 limit of 1 E-06/year CDF and 1 E-07 /year LERF allowed for individual STI changes allowed by the SFCP (i.e., Step 12-A2 of NEI 04-10, Revision 1 ). Based on these observations, the NRC staff concludes that this modeling exclusion is acceptable because it has a minor effect on STI evaluations.

In RAl-1.B (Reference 6), associated with Gap #2, NRC staff noted that there are IFPRA assumptions for which engineering calculations were unavailable, and therefore, requested that the licensee justify that the unsupported assumptions have no impact on the internal flooding risk that impacts STI evaluations.

In its response to RAl-1.B (Reference 2), the licensee explained that the cited engineering calculations to support the IFPRA pipe break scenarios are now available as part of the PRA documentation.

The NRC staff concludes that this issue is resolved because the missing engineering calculations to support the cited assumptions are now part of the IFPRA documentation.

In RAl-1.C (Reference 6), associated with Gaps #3 and #6, NRC staff noted that flooding events in the Fire Pump House and the Condensate Polisher Building were excluded from the IFPRA modeling and requested further justification given that these exclusions could contribute to underestimation of internal flooding risk that impact STI evaluations.

In response to RAl-1.C (Reference 2), the licensee explained that any flooding in the Fire Pump House would not damage risk significant equipment or cause a "malfunction" that would lead the plant to trip. For the Condensate Polisher Building, the licensee explained that the worst-case flooding scenario is a plant trip with loss of main feedwater and loss of the 480 volt building switchgear.

The licensee explained that the conditional core damage probability of this scenario is 4.68E-05, and therefore has a "negligible impact [on] this evaluation" when combined with the flooding frequency.

The NRC staff notes again that the internal flooding CDF and LERF are low, as reported in the licensee's response to the NFPA 805 RAI (Reference 20), dated May 14, 2015, and that a small increase in internal CDF and LERF values due to inclusion of excluded flooding sources would be below the RG 1.17 4 limit of 1 E-06/year CDF and 1 E-07 /year LERF allowed for individual STI changes by the SFCP program. The NRC staff concludes that these modeling exclusions are acceptable because they would have minor impact on STI evaluations.

In RAl-1.D (Reference 6), associated with Gap #4, NRC staff noted that, per the gap assessment finding, the licensee inappropriately applied a reduction factor to convert rupture flow rates to spray flow rates in the IFPRA, and requested that the licensee justify this treatment.

In response to RAl-1. D (Reference 2), the licensee explained that the use of the reduction factor implied in the description in the licensee's analysis was not applied to determine a spray flow rate; rather, industry guidance was used to define spray flow rates. The NRC staff concludes that this issue is resolved because an inappropriate application of a reduction factor to convert rupture flow rates to spray flow rates was not used. In RAl-1.E (Reference 6), associated with Gap #8, NRC staff noted that numerical uncertainties were not propagated as part of IFPRA quantification, and therefore the state of knowledge correlation (SOKC) between failure rates was not considered, which might contribute to underestimation of the flooding risk that impacts STI calculations.

The NRC staff, therefore, requested justification for not incorporating SOKC. In its response to RAl-1. E (Reference 2), the licensee explained that the increase in internal flooding CDF and LERF due to SOKC would be "minor" and would have a "negligible impact on STI evaluations." The NRC staff acknowledges that incorporation of SOKC would have only a small impact on the mean IFPRA CDF and LERF (e.g., might cause a fractional increase of 10 percent) and notes that in STI calculations, the SOKC (with the exception of the failure rate associated with unavailable equipment) would be the same in the baseline and variant cases. In addition, the NRC staff notes that the internal flooding CDF and LERF are low, as reported in the licensee's response to the NFPA 805 RAI (Reference 20), and that a small increase in internal CDF and LERF values that might result from consideration of SOKC would be well below the RG 1.17 4 limit of 1 E-06/year CDF and 1 E-07/year LERF allowed for individual STI changes by the SFCP. The NRC staff concludes that exclusion of the impact of SOKC on internal flooding results is acceptable because it would have minor impact on STI evaluations. In RAl-2 (Reference 6), NRC staff noted that F&O IE-C6-01 from the 2009 internal events PRA full-scope peer review, concerning exclusion of initiating event fault tree model failure modes, did not appear to be resolved for this application and requested justification that the cited modelling exclusions would not impact STI evaluations.

The NRC staff reviewed the licensee's response to RAl-2 (Reference 2), and noted that it was still not clear whether all failure modes cited in the F&O that could impact STI evaluations had been incorporated into the modeling.

Therefore, the NRC staff requested further justification in a second RAl-2.01 submitted to the licensee by letter dated April 12, 2016 (Reference 7). In response to RAI 2.01 by letter dated April 28, 2016 (Reference 3), the licensee stated that the development of the revised model considered failure modes cited in F&O IE-C6-01, where many of those failures were added to the model and others were excluded due to limited contribution.

The licensee further provided an estimate of the overall risk contribution of the initiating event fault trees to the total plant CDF and LERF and stated that the overall risk contribution is very small. The NRC staff concludes that exclusion of some initiating event fault trees related to failures of valves, breakers, sensors, transmitters, and flow diversion paths is acceptable because it would have minor impact on STI evaluations.

Based on the licensee's assessments using the currently applicable PRA standard and revision of RG 1.200, the NRC staff concludes that the level of PRA quality, combined with the evaluation and disposition of gaps, is sufficient to support the evaluation of changes proposed to surveillance frequencies within the SFCP, and is consistent with Regulatory Position 2.3.1 of RG 1.177, Revision 1 (Reference 10). 3.1.4.2 Scope of the PRA The changes to the Administrative Controls section of the TSs will require the licensee to evaluate each proposed change to a relocated surveillance frequency using the guidance contained in NEI 04-10, Revision 1, to determine its potential impact on risk (i.e., CDF and LERF) from internal events, fires, seismic events, other external events, and shutdown conditions.

In cases where a PRA of sufficient scope or quantitative risk models are unavailable, the licensee uses 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 developed PRA models for at-power internal events, internal flooding, and fires, as well as a shutdown PRA model. 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. This is acceptable because the NRG-approved methodology in NEI 04-10, Revision 1, allows for more refined analysis to be performed to support changes to surveillance frequencies in the SFCP. In RAl-3 (Reference 6), the NRC staff noted that the LAR seemed to indicate that use of the fire PRA would be limited to qualitative analysis.

In response to the RAI 3 (Reference 2), the licensee explained that if an SSC modelled in the fire PRA meets the modelling criteria of NEI 04-10, Revision 1, Step 8, then the quantitative evaluation described in Step 12 of the guidance will be completed to evaluate the individual and cumulative impacts on CDF/LERF and the change in CDF/LERF. In RAl-4 (Reference 6), the NRG staff noted that the LAR submittal does not discuss how the SFGP will assess the risk of shutdown events when evaluating STls and requested a description of how shutdown events would be assessed.

In response to RAl-4 (Reference 2), the license explained that there is a shutdown PRA for Waterford 3 that will be used in accordance with guidance in NEI 04-10, Revision 1, to address the contribution of shutdown events in STI evaluations for SSGs that are included in the shutdown PRA model. In LAR Attachment 2 the licensee stated that no Waterford 3 PRA model or applications associated with external hazards (e.g, seismic, high wind, external flooding) exists that could provide quantitative insights to support the STI effort. The licensee further explained that a Waterford 3 seismic PRA was conducted as a one-time review in response to the NRG Individual Plant Examination of External Events (IPEEE) Program, but that the scope was limited to the identification of potential plant vulnerabilities and the understanding of associated severe accident risks. For those cases 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. In PRA RAl-5 (Reference 6), the NRG staff requested that the licensee explain the process for updating the IPEEE evaluations to incorporate new information when performing the qualitative or bounding analyses.

In its response to the RAl-5 (Reference 2), the licensee explained that the internal procedure for maintaining and updating the PRA ensures that needed improvements to external event evaluations (separate from the PRA) are also considered during periodic updates of the PRA models. The licensee explained that recent industry experience, new research, changes in industry standards, and other information are reviewed during the periodic update and will be used as applicable in updating the external event evaluations.

This supports the licensee's conclusion that the IPEEE analysis of external hazards, updated to incorporate new information, can be used to support the SFGP. The NRG staff notes that this approach is in accordance with NEI 04-10, Revision 1. Based on the above, the NRG staff concludes that through the application of NRG-approved NEI 04-10, Revision 1, 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 of RG 1.177, Revision 1 (Reference 10). 3.1.4.3 PRA Modeling The licensee's methodology includes the 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 CCF 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 (Reference 11 ), and by sensitivity studies identified in NEI 04-10, Revision 1. Thus, the NRG staff concludes that through the application of NRG-approved NEI 04-10, Revision 1, the Waterford 3 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 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.

LAR Attachment 2, Section 3.2, "Identification of Key Assumptions," states that determination of standby failure rates is a key source of uncertainty and therefore sensitivity studies will be performed on standby failure rates for STI evaluations.

The NRC staff notes that NEI 04-10, Revision 1, provides guidance on how to adjust the time-related failure contribution of SSCs and how to perform needed sensitivity studies (i.e., Step 14). NEI 04-10, Revision 1, criteria 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 (Reference 10), which permits separation of the failure rate contributions into demand and standby for evaluation of SRs. If the available data do not support distinguishing between the time-related failures and demand failures, then the change to surveillance frequency is conservatively assumed to impact the total failure probability of the SSC, including both standby and demand contributions.

The SSC failure rate (per unit time) is assumed to be unaffected by the change in test frequency, such that the failure probability is assumed to increase linearly with time, and will be confirmed by the required monitoring and feedback implemented after the change in surveillance frequency is implemented.

The NEI 04-10 process requires consideration of qualitative sources of information with regards 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 process is not reliant upon risk analyses as the sole basis for the proposed changes. The potential benefits of a reduced surveillance frequency, including reduced downtime and reduced potential for restoration errors, test-caused transients, and test-caused wear of equipment, are identified qualitatively, but not quantitatively assessed.

Thus, the NRC staff concludes that through the application of NRC-approved NEI 04-10, Revision 1, the licensee has employed reasonable assumptions with regard to extensions of STls, and is consistent with Regulatory Position 2.3.4 of RG 1.177, Revision 1. NEI 04-10, Revision 1, requires performance monitoring of SSCs whose surveillance frequencies have been revised as part of a feedback process to assure that the change in test frequency has not resulted in degradation of equipment performance and operational safety. The monitoring and feedback includes consideration of Maintenance Rule monitoring of equipment performance.

In the event of SSC performance degradation, the surveillance frequency will be reassessed in accordance with the methodology, in addition to any corrective actions which may be required by the Maintenance Rule. 3.1.4.5 Sensitivity and Uncertainty Analyses By specifying that the TSs require that changes to the frequencies listed in the SFCP be made in accordance with NEI 04 10, Revision 1, the licensee will be required to conduct sensitivity studies that assess the impact of uncertainties from key assumptions of the PRA, uncertainty in the failure probabilities of the affected SSCs, impact on the frequency of initiating events, and any identified deviations from CC II of the 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 will also be required to perform monitoring and feedback of SSC performance once the revised surveillance frequencies are implemented.

Thus, the NRC staff concludes that through the application of NRG-approved NEI 04-10, Revision 1, the licensee has appropriately considered the possible impact of PRA model uncertainty and sensitivity to key assumptions and model limitations and is consistent with Regulatory Position 2.3.5 of RG 1.177, Revision 1. 3.1.4.6 Acceptance Guidelines The licensee will be required to quantitatively evaluate the change in total risk (including internal and external events contributions) in terms of CDF and LERF for both the individual risk impact of a proposed change in surveillance frequency and the cumulative impact from all individual changes to surveillance frequencies using NEI 04-10, Revision 1, in accordance with the TS SFCP. Each individual change to surveillance frequency must show a risk impact below 1 E-6 per year for change to CDF, and below 1 E-7 per year for change to LERF. These changes to CDF and LERF are consistent with the acceptance criteria of RG 1.17 4, Revision 2 (Reference 9), for very small changes in risk. Where the RG 1.17 4, Revision 2, acceptance criteria are not met, the process in NEI 04-10, Revision 1, either considers revised surveillance frequencies which are consistent with RG 1.17 4, Revision 2, or the process terminates without permitting the proposed changes. Where quantitative results are unavailable for comparison with the acceptance guidelines, appropriate qualitative analyses are required to demonstrate that the associated risk impact of a proposed change to surveillance frequency is negligible or zero. Otherwise, bounding quantitative analyses are required which demonstrate the risk impact is at least one order of magnitude lower than the RG 1.17 4, Revision 2 (Reference 9), acceptance guidelines for very small changes in risk. In addition to assessing each individual SSC surveillance frequency change, the cumulative impact of all changes must result in a risk impact less than 1 E-5 per year for change to CDF, and less than 1 E-6 per year for change to LERF, and the total CDF and total LERF must be reasonably shown to be less than 1 E-4 per year and 1 E-5 per year, respectively.

These values are consistent with the acceptance criteria of RG 1.17 4, Revision 2, as referenced by RG 1 .177, Revision 1 (Reference 10), for changes to surveillance frequencies.

Consistent with the NRC's SE dated September 19, 2007, for NEI 04-10, Revision 1, the TS SFCP 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 NRC staff further notes that the licensee 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 per year for CDF and 5E-9 per year for LERF) once the baseline PRA models are updated to include the effects of the revised surveillance frequencies.

The quantitative acceptance guidance of RG 1.17 4, Revision 2, is supplemented by qualitative information to evaluate the proposed changes to surveillance frequencies, including industry and plant-specific operating experience, vendor recommendations, industry standards, the 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 components.

The licensee's application of NRG-approved NEI 04-10, Revision 1, provides acceptable methods for evaluating the risk increase associated with proposed changes to surveillance frequencies, consistent with Regulatory Position 2.4 of RG 1.177, Revision 1. Therefore, the NRC staff concludes that the 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 adoption of TSTF-425, Revision 3, requires application of NRG-approved NEI 04-10, Revision 1, in the SFCP. NEI 04-10, Revision 1, requires performance monitoring of SSCs whose surveillance frequencies have been revised as part of a feedback process to assure that the change in test frequency has not resulted in degradation of equipment performance and operational safety. The monitoring and feedback include consideration of Maintenance Rule monitoring of equipment performance.

In the event of SSC performance degradation, the surveillance frequency will be reassessed in accordance with the methodology, in addition to any corrective actions which may be required by the Maintenance Rule. The performance monitoring and feedback specified in NEI 04-10, Revision 1, is sufficient to reasonably assure acceptable SSC performance and is consistent with Regulatory Position 3.2 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 Addition of Surveillance Frequency Control Program to Administrative Controls The licensee proposed including the SFCP and specific requirements into the Waterford 3 TSs, Section 6.5.18, 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 that 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 Technical Specifications Initiative 5b, Risk Informed Method for Control of Surveillance Frequencies," Revision 1. c. The provisions of Surveillance Requirements 4.0.2 and 4.0.3 are applicable to the Frequencies established in the Surveillance Frequency Control Program. The proposed program is consistent with the model application of TSTF-425, and therefore, the staff concludes that it is acceptable.

3.3 Deviations from TSTF-425 and Other Changes In Attachment 1, Section 2.2 of the LAR, the licensee identified optional changes and variations from the approved TSTF-425, Revision 3. The NRC staff reviewed the changes and variations and made the following determinations:

1. The insert provided in TSTF-425 pertaining to text that describes each frequency relocated to the SFCP has been revised from "The Surveillance Frequency is based on operating experience, equipment reliability, and plant risk and is controlled under the Surveillance Frequency Control Program" to read "The Surveillance Frequency(ies) is/are based on operating experience, equipment reliability, and plant risk and is/are controlled under the Surveillance Frequency Control Program." As the licensee stated in paragraph 1 of Section 2.2 of the LAR, this variation was consistent with the inserts proposed by TSTF-425, Revision 3. The NRC staff determined that this is, therefore acceptable and the SRs will continue to meet 10 CFR 50.36(c)(3).

2. In the guidance in NUREG-1432, Revision 4, the Administrative Controls are located in Section 5.0. The approved programs for Waterford 3 are described in Section 6.0, "Administrative Controls," of the Technical Specifications.

Therefore, the Surveillance Frequency Control Program description will be located at 6.5.18 of the Waterford 3 TS in lieu of at 5.5.20 as in the NUREG-1432 guidance.

The description of the program is the same as in the approved TSTF-425, Revision 3. The NRC staff determined that this change is administrative in nature and is an acceptable variation from the approved TSTF tailored to fit the Waterford 3 TSs. Therefore the SRs will continue to meet 10 CFR 50.36(c)(3).

3. The licensee additionally proposed to remove a reference to the prescribed surveillance frequency

("at a frequency of 18 months on a STAGGERED TEST BASIS") of SR 4.7.6.1.b from TS 6.5.17 paragraph

d. Removal of this language from paragraph d was necessary so that the frequency of SR 4.7.6.1.b could be controlled by the new surveillance frequency control program of TSTF-425, Revision 3 upon approval of the LAR. The NRC staff determined that removal of the language does not otherwise affect the readability or intent of TS 6.5.17; therefore this change is acceptable and consistent with TSTF-425, Revision 3. TS 6.5.17 will continue to meet 10 CFR 50.36(c)(3).

4. Attachment 7 of the LAR contained a cross-reference between NUREG-1432 surveillances included in TSTF-425, Revision 3 versus Waterford 3 surveillances.

The cross reference served only as an aid in the NRC staff review and provided information as stated in paragraph 4 of section 2.2 of the LAR. 5. Paragraphs 5, 7 and the conclusion of Section 2.2 of the LAR identified that the Waterford 3 TSs are custom and contain plant-specific SRs not included in the approved TSTF-425, Revision 3. Approved TSTF-425, Revision 3 states, "The proposed change relocates all periodic Surveillance Frequencies from the Technical Specifications and places the Frequencies under licensee control in accordance with a new program" and "All surveillances are relocated except. .. [four exclusion criteria for the surveillance frequencies are listed]." It does not add, delete, or modify the content of the surveillance requirements themselves.

These statements denote that TSTF-425, Revision 3, applies to all surveillances, including the Waterford 3 plant-specific surveillances, that are periodic and do not meet one of the exclusion criteria.

Application of the TSTF to Waterford 3's custom TS format is in accordance with the Commission's final policy statement on TSs, as published in the Federal Register on July 22, 1993 (58 FR 39132). The NRC staff reviewed the marked-up SRs in the LAR and the supplement submitted by letter dated March 3, 2016, to ensure that no surveillances were included that matched the exclusion criteria.

The NRC staff determined that all marked-up surveillances included in the original LAR as supplemented, or corrected in the supplement, were included within the scope of approved TSTF-425, Revision 3. Therefore the SRs will continue to meet 10 CFR 50.36(c)(3).

6. The NRC staff reviewed only the changes proposed by the licensee for Waterford

3. Paragraph 6 of Section 2.2 of the LAR mentions that there are SRs contained in NUREG-1432, Revision 4, and in approved TSTF-425, Revision 3 that do not appear in Waterford 3 TSs. These are not within the scope of this plant specific Waterford 3 change and therefore were not reviewed.

3.4 Summary and Conclusions The NRC staff has reviewed the licensee's proposed relocation of some surveillance frequencies to a licensee-controlled document, and controlling changes to surveillance frequencies in accordance with a new program, the SFCP, which is identified in the Administrative Controls of the TSs. The NRC staff confirmed that this amendment does not relocate surveillance frequencies that reference other approved programs for the specific interval, 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 SFCP and TSs Section 6.0, Subsection 6.5.18 references NEI 04-10, Revision 1, which provides a risk-informed methodology using plant-specific risk insights and performance data to revise surveillance frequencies within the SFCP. This methodology supports relocating surveillance frequencies from TSs to a licensee-controlled document, provided those frequencies are changed in accordance with the NRG-approved NEI 04-10, Revision 1, which is specified in the Administrative Controls of the TSs. The licensee-proposed adoption of TSTF-425, Revision 3, and the risk-informed methodology of NRG-approved NEI 04-10, Revision 1, as referenced in the Administrative Controls of TSs, satisfies the key principles of risk-informed decisionmaking applied to changes to TSs, as delineated in RG 1.177 and RG 1.17 4, in that:

The proposed change meets current regulations;

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

The proposed change maintains sufficient safety margins;

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

The impact of the proposed change is monitored with performance measurement strategies.

Section 50.36(c) of 10 CFR discusses the categories that will be included in TSs. Section 50.36(c)(3) of 10 CFR discusses the specific category of SRs and 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." The NRC staff finds that with the proposed relocation of surveillance frequencies to a licensee-controlled document and administratively controlled in accordance with the TS SFCP, the licensee continues to meet the requirements in 10 CFR 50.36.

4.0 STATE CONSULTATION

In accordance with the Commission's regulations, the Louisiana State official was notified of the proposed issuance of the amendment.

The State official had no comments.

5.0 ENVIRONMENTAL CONSIDERATION The amendment changes a requirement with respect to installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20 and changes the surveillance requirements.

The NRC staff has determined that the amendment involves no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite, and that there is no significant increase in individual or cumulative occupational radiation exposure.

The Commission has previously issued a proposed finding that the amendment involves no significant hazards consideration, and there has been no public comment on such finding published in the Federal Register on September 1, 2015 (80 FR 52805). Accordingly, the amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9).

Pursuant to 10 CFR 51.22(b) no environmental impact statement or environmental assessment need be prepared in connection with the issuance of the 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 amendments will not be inimical to the common defense and security or to the health and safety of the public.
