ENTERGYS ANSWER OPPOSING STATE OF NEW YORKS PETITION TO INTERVENE AND REQUEST FOR HEARING I. INTRODUCTION Pursuant to 10 C.F.R. § 2.309(i)(1), Entergy Nuclear Operations, Inc. (Entergy) submits this answer opposing the petition to intervene and request for hearing filed on May 18, 2015, by the State of New York (New York or Petitioner).1 New York seeks to intervene in the proceeding associated with Entergys December 9, 2014, license amendment request (LAR),
which seeks to revise Indian Point Unit 2 (Unit 2 or IP2) Technical Specification 5.5.14, Containment Leakage Rate Testing Program, to extend the frequency of the Containment Integrated Leak Rate Test (ILRT) or Type A Test for Unit 2 from once every 10 years to once every 15 years on a permanent basis.2 New York proffers two proposed contentionsa safety contention (NYS-1) and an environmental contention (NYS-2).3 For the reasons set forth below, the Atomic Safety and Licensing Board (Board) should deny the Petition in its entirety. Although Entergy does not contest New Yorks standing to 1
State of New York Petition to Intervene and Request for Hearing (May 18, 2015) (Petition) (ML15138A415).

intervene in this proceeding,4 New York has failed to submit an admissible contention. The deficiencies in New Yorks proposed contentions are many, but perhaps the most obvious defect is New Yorks failure to provide any expert opinion or relevant technical information to support its overarching claim that issuance of the requested license amendment will imperil New Yorks citizens and environment. As discussed herein, New York provides no valid factual or technical support for that claimamong many otherscontrary to the requirements of 10 C.F.R.
§ 2.309(f)(1)(v).5 Contrary to the requirement of 10 C.F.R. § 2.309(f)(1)(vi), New York also fails to directly challenge the contents of Entergys license amendment application,6 which contains a detailed technical evaluation of the proposed extension of the interval for the primary containment ILRT from 10 to 15 years.7 That evaluation is supported by a detailed, plant-specific risk impact assessment that was prepared by a qualified probabilistic risk assessment (PRA) vendor, which concluded that increasing the ILRT interval on a permanent basis to a one-in-fifteen year frequency is not considered to be significant since it represents only a small change in the IP2 risk profiles.8 New York ignores these technical evaluations, and instead relies principally on 4
See Petition at 2-4. New York includes a list of historic, unique or otherwise significant sites within 50 miles of the IP2 site as Attachment 1 to its Petition, and a map of reservoirs in the vicinity of the IP2 site as Attachment
- 2. Insofar as New York appears to have included those attachments to support its claim of standing, which Entergy does not dispute, Entergy does not further discuss the attachments, which have no apparent nexus to the ILRT-related subject matter of Entergys pending license amendment request.
5 See Pub. Serv. Co. of N.H. (Seabrook Station, Units 1 & 2), ALAB-942, 32 NRC 395, 428 (1990) (stating that petitioner must provide a sufficient foundation to warrant further exploration) (citation omitted); Yankee Atomic Elec. Co. (Yankee Nuclear Power Station), CLI-96-7, 43 NRC 235, 262 (1996) (holding that a petitioner bears the burden to present the factual information or expert opinions necessary to support its contention adequately, and failure to do so requires the licensing board to reject the contention).

Reg. 33,168, 33,170 (Aug. 11, 1989) (stating that petitioner must read the pertinent portions of the license application . . . state the applicants position and the petitioners opposing view, and explain why it disagrees with the applicant).

conclusory assertions by counsel and discussion of historical containment-related incidents that occurredand were addressed35 years or more ago.9 New York also overlooks the fact that the ILRT is only one of numerous tests and inspections that Entergy performs to ensure that the IP2 containment performs its intended safety function. As discussed in the LAR and Section III below, in addition to the Type A tests (ILRTs),
Entergy performs: (1) Type B tests for the containment penetrations and airlocks, (2) Type C tests for the containment isolation valves, (3) IWE internal visual inspections of the containment liner every three and one-third years, (4) IWL external visual inspections of the containment concrete surfaces every five years, (5) general visual inspections of the outside surfaces of the containment (including the penetrations) every two years per plant procedure 2-PI-2Y001, and (6) general visual inspections of the internal and external containment surfaces prior to each ILRT and at a periodic interval between tests based on the performance of the containment system. As further discussed in Section III, IP2 has a weld channel pressurization system that allows for real-time monitoring of potential leakage through the portions of the containment boundary that it pressurizes. None of these other tests, inspections, or systems is affected by the requested change to the ILRT frequency.
Finally, New Yorks proposed contentions raise issues that are neither within the scope of this LAR proceeding nor material to the Staffs required findings, contrary to the requirements of 10 C.F.R. § 2.309(f)(1)(iii) and (iv). In particular, New York raises issues related to the Indian Point license renewal severe accident mitigation alternatives (SAMA) analysis and improperly 9
See, e.g., Petition at 1 (Entergys LAR would increase the risk that the citizens and environment of the State will be exposed to the release of radioactive materials.); id. at 12 (The history of the IP2 containment liner makes it particularly ill-suited for the reduced safety-margins proposed by Entergy.). These, like many statements in the Petition, are unaccompanied by citations. Moreover, as discussed herein, insofar as New York discusses specific supporting documents in its Petition, it repeatedly takes statements out of context and ignores other material information in those documents that contradicts its position.

challenges the Nuclear Regulatory Commission (NRC or Commission) Staffs proposed no significant hazards consideration determination for the LAR.10 For all these reasons, the Petition should be denied in its entirety.
II. PROCEDURAL HISTORY On December 14, 2014, Entergy filed with the NRC an application to amend the IP2 operating license pursuant to 10 C.F.R. § 50.90. The proposed amendment would revise Technical Specification 5.5.14, Containment Leakage Rate Testing Program, to extend the frequency of the ILRT from once every 10 years to once every 15 years on a permanent basis.11 As discussed in Section III.E of this brief, the NRC approved a license amendment that extended the Unit 2 ILRT interval on a one-time basis from ten years to 15 years in August 2002. In recent years, the NRC has approved numerous one-time and permanent extensions of the ILRT interval from 10 to 15 years for various plants based on the performance-based NRC regulations and NRC-approved industry guidelines (i.e., topical reports) discussed below.12 Entergys application contains a detailed technical evaluation (Attachment 1) of the proposed Technical Specification changes, which are in accordance with 10 C.F.R. Part 50, Appendix J, and the NRC-approved guidance document NEI 94-01, Rev. 2-A, Industry Guideline for Implementing Performance Based Option of 10 CFR Part 50, Appendix J (Oct. 2008).
Among other things, the LAR evaluation discusses the safety significance of the proposed Technical Specification change in accordance with the criteria of 10 C.F.R. § 50.92 (Issuance of 10 See Petition at 8-9, 19-22.
11 See LAR at 1.
12 Examples of previous NRC-approved ILRT interval extensions include Nine Mile Point, Unit 2 (permanent extension of ILRT interval from 10 to 15 years in 2010 (ML100730032)); Arkansas Nuclear One, Unit 2 (permanent extension of ILRT interval from 10 to 15 years in 2011 (ML110800034)); Palisades (permanent extension of ILRT interval from 11.25 to 15 years in 2012 (ML120740081)); Indian Point, Unit 3 (permanent extension of ILRT interval from 10 to 15 years in 2015 (ML15028A308)); Braidwood, Units 1 and 2 (one-time extension of ILRT amendment from 10 to 15 years in 2008 (ML080640290));Limerick, Units 1 and 2 (one-time extension of ILRT amendment from 10 to 15 years in 2008 (ML080310769)); and North Anna, Unit 2 (one-time extension of ILRT amendment from 10 to 15 years in 2008 (ML081510562)).

Amendment).13 Entergy determined that the proposed amendment does not involve a significant hazards consideration under 10 C.F.R. § 50.92(c).14 In addition, the application includes a detailed confirmatory risk impact assessment (Attachment 3) that evaluates the risk associated with implementing a permanent extension of the ILRT interval from 10 years to 15 years.15 The impact assessment demonstrates that increasing the ILRT interval is not risk significant because it represents only a small change in the IP2 plant-specific risk profile.16 The NRC accepted the LAR for docketing, and published a Hearing Notice on March 17, 2015.17 The Hearing Notice included the NRC Staffs proposed no significant hazards consideration determination and provided interested parties 60 days (i.e., until May 18, 2015) to request a hearing related to the LAR.18 New Yorks Petition was filed on May 18, 2015. As noted above, the Petition contains a proposed safety contention (NYS-1) and a proposed environmental contention (NYS-2). In brief, NYS-1 alleges that Entergys LAR fails to demonstrate that it complies with 10 C.F.R. §§ 50.40 and 50.92 or 10 C.F.R. Part 50, Appendix J, and therefore does not provide reasonable assurance of adequate protection for the public health and safety, as required by the Atomic Energy Act of 13 See LAR, attachment 1 at 17-18.

15 See id., attachment 3. Entergy third-party vendor ERIN Engineering & Research, Inc. prepared the risk impact assessment in accordance with NRC-approved industry guidelines discussed in Section III below. See id. at 1-1.
16 See id. at 7-2. This conclusion is consistent with the general findings of previous NRC and industry studies that the risk impact associated with extending the ILRT interval to one in 15 years is small. See LAR, attachment 1, at 15.

18 See id. at 13,903, 13,905-06. The NRCs no significant hazards consideration determination is consistent with the NRCs very recent approval of an amendment to the Indian Point Unit 3 (IP3) operating license allowing a permanent extension of the Type A primary containment ILRT frequency from once every 10 years to once every 15 years. See Letter from Douglass V. Picket, NRC, to Vice President of Operations, Entergy, Indian Point Nuclear Generating Unit No. 3 - Issuance of Amendment Re: Extension of the Type A Containment Integrated Leak Rate Test Frequency from 10 to 15 Years (TAC No. MF3426) (Mar. 13, 2015)
(ML15028A308).

1984, as amended (AEA).19 NYS-2 asserts that proposed license amendment is not categorically exempt from environmental review under 10 C.F.R. § 51.22(c)(9), and that Entergy and the NRC Staff must perform an environmental review to meet the requirements of the National Environmental Policy Act (NEPA).20 Entergy timely files this answer opposing the Petition in accordance with 10 C.F.R.
§ 2.309(i)(1).
III. REGULATORY BACKGROUND A. Safety Function of the IP2 Containment Structure The IP2 containment structure is a steel-lined reinforced concrete vertical cylinder with a flat base mat and hemispherical dome that completely encloses the reactor and reactor coolant system (RCS).21 The containment liner, which covers the inner surface of the concrete containment structure, provides an essentially leak-tight barrier against leakage out of the containment during an accident.22 The containments intended function is to ensure that any leakage of radioactive materials to the environment, even if a gross failure of the RCS were to occur, does not result in off-site doses greater than the limits of 10 C.F.R. Part 100.23 The IP2 containment pressure boundary consists of the steel-lined containment structure, containment access penetrations, and other process piping and electrical penetrations.24 19 Petition at 5.
20 Id. at 20.
21 See Letter from Patrick D. Milano, NRC, to Michael, R. Kansler, Entergy, Indian Point Nuclear Generating Unit No. 2 - Amendment Re: One-Time Deferral of Containment Integrated Leak Rate Test (TAC No. MB2414),

22 The containment liner is carbon steel. Therefore, the only credible degradation mechanism is general corrosion caused by continuous exposure of the steel to a corrosive environment.

IP2 is one of a very few U.S. plants to have a system that pressurizes the containment weld channels and certain containment penetrations during normal plant operation.25 Specifically, the IP2 Containment Weld Channel and Penetration Pressurization System (WC&PPS) keeps the channels pressurized during normal plant operation and, by design, during accidents.26 The pressure is maintained at or above calculated peak containment accident pressure. The WC&PPS provides for continuous on-line measuring of leakage through the portions of the containment boundary that it pressurizes, and thereby also allows plant operators to promptly detect increased leakage during normal operation (e.g., in the unlikely event that a through-wall flaw develops or an isolation valve fails open).27 The WC&PPS also prevents containment atmosphere from leaking out of the containment through the liner welds and penetrations, even with a failure, during a postulated accident.28 In this regard, the WC&PPS is an engineered safety feature that would act to prevent containment leakage through potential flaws in the liner welds.29 B. Applicable NRC Requirements, Including Required Leakage Tests To ensure that reactor containments are maintained properly and able to perform their design-basis functions, NRC regulations require that licensees conduct leakage rate testing and inspections of containments and associated pressure-retaining components at periodic intervals.30 Under 10 C.F.R. § 50.54(o), primary reactor containments are subject to the leakage testing requirements contained in 10 C.F.R. Part 50, Appendix J, Primary Reactor Containment Leakage 25 See id. at 5.
26 See id.
27 See id. IP2 Technical Specification 3.5.16 requires the system to be operable in modes above cold shutdown and places a limit on the total rate of leakage out of the WC&PPS during normal operation. Id. If the leakage rate exceeds the limit, then Entergy must reduce the leakage rate below the limit or shut down the plant. Id. Very limited portions of the WC&PPS system (approximately 4% of the total number of penetrations/weld channels supplied with Weld Channel air) have been retired in place.

Testing for Water-Cooled Power Reactors. Appendix J identifies three types of required tests:31 (1) Type A (ILRT) tests, which measure the containment overall integrated leakage rate;32 (2)
Type B local leakage-rate tests (LLRTs), which detect local leaks and measure leakage across pressure-containing or leakage limiting boundaries (other than valves) for containment penetrations; and (3) Type C LLRTs, which measure containment isolation valve leakage.33 The instant LAR, if approved, would modify only the Type A testing interval. The Type B and Type C testing intervals would not change. In addition, the frequencies of the general visual inspections discussed in Section III.F will not change.
C. Appendix J Test Program Option B and Related NRC-Approved Guidance In 1995, the NRC amended Appendix J to provide a performance-based Option B for the containment leakage testing requirements.34 Option B allows for test intervals for Type A, Type B, and Type C testing to be determined by using a performance-based approach.35 Performance-based test intervals are based on consideration of a components operating history failure risk.36 If selected, Appendix J, Option B requires that a Type A test be conducted at a periodic interval based on historical performance of the overall containment system.37 31 See 10 C.F.R. pt. 50, app. J, Option B, secs. III.A. & III.B.
32 See id. sec. III.A. The Type A test or ILRT measures integrated leakage rate from all potential leakage paths, including containment liner welds, valves, fittings, and components that penetrate containment. See 2002 IP2 Safety Evaluation at 2. These tests typically involve pressurizing the containment atmosphere to a specified test pressure for a duration that is sufficient to determine what the containment leakage would be under design-basis accident conditions. See id. The acceptance criteria for the Type A test and the Technical Specification leakage limits are conservatively established to ensure that, in the event of a design-basis accident, the dose received by a member of the general public will not exceed the limits specified in 10 C.F.R. Part 100. See id.

Current IP2 Technical Specification 5.5.14 states that leakage rate testing shall be performed as required by Option B, as modified by approved exemptions, and in accordance with the guidelines contained in NRC Regulatory Guide 1.163.38 Regulatory Guide 1.163 endorses Nuclear Energy Institute (NEI) Report 94-01, Revision 0,39 which NEI has since revised several times in response to subsequent developments and NRC-industry interactions, including NRC Staff requests for additional information (RAIs).40 Revision 2-A of NEI 94-01 added guidance for extending Type A ILRT surveillance intervals beyond ten years.
NEI 94-01, Revision 2-A, the revision referenced in the LAR, states that plant-specific confirmatory analyses are required when extending the Type A ILRT interval beyond ten years.41 Section 9.2.3.4 of NEI 94-01 states that the assessment should be performed using the approach and methodology described in Electric Power Research Institute (EPRI) Technical Report (TR) 1009325, Revision 2-A, Risk Impact Assessment of Extended Integrated Leak Rate Testing Intervals.42 The analysis is to be performed by the licensee and retained in the plant documentation and records as part of the basis for extending the ILRT interval. In a safety evaluation issued on June 25, 2008, the NRC Staff found the methodology in NEI 94-01, Revision 2, and EPRI TR-1009325, Revision 2, to be acceptable for referencing by licensees proposing to 38 See LAR, attachment 2; NRC Regulatory Guide 1.163, Performance-Based Containment Leak-Rate Testing Program (Sept. 1995) (ML003740058).

40 NEI submitted NEI 94-01, Revision 1 to the NRC in December 2005, and Revision 2 in August 2007. The NRC Staff approved Revision 2 as a topical report in a safety evaluation issued on June 25, 2008. At the Staffs request, NEI issued an NRC-approved version as NEI 94-01, Rev. 2-A in October 2008. (The industry typically resubmits a topical report with the suffix -A to denote that the document has been approved by the NRC.)

amend their licenses to permanently extend the ILRT interval to 15 years, provided that certain conditions set forth in Section 4.2 of the NRC Staffs safety evaluation are satisfied.43 D. Leakage Rate Test Acceptance Criteria The acceptance criteria for containment leakage rate tests are typically expressed in terms of the maximum allowable containment leakage rate, La, which would occur at the calculated peak containment internal pressure related to the design-basis loss-of-coolant accident (LOCA).44 Plant Technical Specifications typically specify values for La in terms of the allowable weight percent of the containment atmosphere that may leak in 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> at the peak containment internal pressure (Pa).45 The acceptance criteria for Type A tests, and the combined Type B and Type C tests, are typically specified as multiples of La.46 The IP2 maximum allowable containment leakage rate and leakage test acceptance criteria are specified in the plant Technical Specifications.47 The maximum allowable containment leakage rate (La) is 0.1 weight percent per day of the containment steam air atmosphere (at 47 pounds per square inch gauge (psig) and 271 degrees Fahrenheit (°F)).48 The as-found ILRT acceptance criterion is 1.0La, and the as-left ILRT acceptance criterion is 0.75La.49 The five Type A (ILRT) tests performed at IP2 all have been successful; i.e., met the as-found acceptance criterion of 1.0La.50 43 See Final Safety Evaluation by the Office of Nuclear Reactor Regulation, Nuclear Energy Institute (NEI) Topical Report (TR) 94-01, Revision 2, Industry Guideline for Implementing Performance-Based Option of 10 CR Part 50, Appendix J and Electric Power Research Institute (EPRI) Report No. 1009325, Revision 2, August 2007, Risk Impact Assessment of Extended Integrated Leak Rate Testing Intervals, Nuclear Energy Institute Project No. 689 (June 25, 2008) (ML081140105).

The performance leakage rate is equal to the sum of the measured Type A test upper confidence limit (UCL) and the total as-left minimum pathway leakage rate (MNPLR) of all Type B or Type C pathways isolated during performance of the Type A test.

E. The IP2 Containment Leakage Rate Testing Program By letters dated August 7, 1996 and March 12, 1997, IP2 submitted a Technical Specification change request to implement Appendix J, Option B. The NRC approved that request as Amendment 190 issued on April 10, 1997. With the approval of the amendment, IP2 transitioned to a performance-based 10-year frequency for the Type A tests. On July 13, 2001 Entergy submitted an amendment request to extend the ILRT interval on a one-time basis from ten years to 15 years. The NRC approved that amendment request, as later supplemented, in Amendment 232 to the license issued on August 5, 2002. The current proposed extension of the primary containment ILRT from ten to 15 years, if approved, would mean that the next scheduled ILRT would need to be completed by March 2021 (instead of March 2016).51 Entergy previously conducted periodic ILRTs in 1979, 1984, 1987, 1991, and 2006.
F. Required Code Inspections of the Reactor Containment 10 C.F.R. Part 50, Appendix J, Option B, paragraph III.A requires that, prior to each Type A test and at a periodic interval between tests based on the performance of the containment system, a general visual inspection of the accessible interior and exterior surfaces of the containment system be performed to identify structural deterioration that may affect the containment leak-tight integrity.52 In addition, inspections are performed as part of the Containment Inservice Inspection (ISI) Plan to implement the requirements of American Society performance criterion for a Type A test is met if the performance leakage rate is less than 1.0La. The acceptance criterion for the as-left Type A test is set at 75% of the allowed leakage rate (i.e., 0.75La), which provides a minimum 25% margin to address the possibility of containment leak tightness degradation over time between Type A tests while continuing to maintain less than the maximum allowable containment leakage rate (La).
50 See LAR, attachment 1, at 5-6 (Past IP2 ILRT results have confirmed that the containment is acceptable with respect to the design criterion of 0.1% leakage of containment air weight at the design basis loss of coolant accident pressure (La).).
51 Since the last ILRT was completed in April 2006, and the next one would be performed in March 2020 based on the current refueling outage schedule (if the LAR is granted), the actual interval would be about 14 years. See LAR, attachment 1, at 10.

NEW YORKS PROPOSED CONTENTIONS ARE INADMISSIBLE A. Governing Legal Standards for Contention Admissibility Petitions to intervene must set forth with particularity the contentions a petitioner seeks to have litigated in a hearing.61 The requirements for an admissible contention are set forth in 10 C.F.R. § 2.309(f)(1)(i)-(vi) and also described in the Hearing Notice.62 The Commissions contention admissibility requirements are strict by design.63 They seek to ensure that NRC hearings serve the purpose for which they are intended: to adjudicate genuine, substantive safety and environmental issues placed in contention by qualified intervenors.64 As such, the requirements reflect a deliberate effort to prevent the major adjudicatory delays caused in the past by ill-defined or poorly-supported contentions that were admitted for hearing although based on little more than speculation.65 To warrant an adjudicatory hearing, proposed contentions thus must have some reasonably specific factual or legal basis.66 Under 10 C.F.R. § 2.309(f)(1), a petitioner must explain the basis for each proffered contention by stating alleged facts or expert opinions that support the petitioners position and on 60 See LAR, attachment 1, at 10.

Proposed Contention NYS-1 Is Inadmissible Because It Fails to the Meet the Requirements of 10 C.F.R. § 2.309(f)(1)(iii)-(vi)
Proposed Contention NYS-1 claims that Entergys LAR does not demonstrate that it complies with 10 C.F.R. §§ 50.40 and 50.92 or 10 C.F.R. Part 50, Appendix J and, therefore, does not provide reasonable assurance of adequate protection for the public health and safety.71 New York presents six principal arguments or bases in support of its contention, which, for purposes of this response, Entergy refers to as Bases 1 through 6. They are: (1) Entergy has not adequately considered the plant-specific history of the IP2 containment liner;72 (2) Entergys request to postpone the containment integrity testing ignores recent inspections that revealed allegedly significant corrosion and other wear in the containment liner;73 (3) Entergy did not adequately consider new seismic data;74 (4) the LAR poses a significant hazard consideration under 10 67 10 C.F.R. § 2.309(f)(1)(ii), (v).

C.F.R. § 50.92(c);75 (5) the LAR relies on Entergys allegedly deficient license renewal SAMA analysis;76 and (6) Entergys alleged desire to reduce costs and maximize revenues also does not justify rolling back this important safety-related test.77 As demonstrated below, none of those bases supports the admission of Proposed Contention NYS-1.
- 1. Basis 1: Alleged Unique Degradation History of the IP2 Containment Liner New York asserts that conducting ILRTs at intervals exceeding 10 years is insufficient in view of certain historical unusual degradation events involving the IP2 containment liner.78 Specifically, it cites (1) buckling of the liner during initial plant construction in 1968, (2) deformation of the liner caused by a jet of steam and hot water in 1973, and (3) corrosion of the liner due to a flooding event in 1980.79 According to New York, these damaging incidents make IP2 ill-suited for the relaxed monitoring proposed by Entergy.80 New York further asserts that Entergys evaluation of the safety risk posed by the reduced ILRT inspection frequency fails to consider the cited history of events affecting the IP2 containment liner.81 For the reasons discussed below, none of these claims supports the admission of NYS-1.
As a preliminary matter, New York fails to explain how any of these historical eventsall of which occurred several decades agois germane to the instant LAR, which seeks to extend the ILRT interval by five years in accordance with current NRC regulations and NRC-approved industry guidelines. At a minimum, New York should have provided some assessment, preferably furnished by a qualified technical expert, explaining the significance of these events and how they 75 Id. at 8.

purportedly bear on the adequacy of the IP2 Containment Leakage Rate Testing Program. Indeed, such an assessment would have been particularly warranted here, given the specific, documented, and confirmed corrective actions taken in response to those events, and the various ILRTs, LLRTs, and visual/volumetric inspections performed to date (which have provided no indications that the IP2 containment is unable to perform its design function of maintaining integrity during accident conditions).82 Instead, New York relies solely on unsubstantiated claims by counsel, and ignores critical information contained in the very documents it references in its Petition.83 For example, New York asserts, without any supporting expert opinion or other credible factual basis, that performing ILRTs for the IP2 containment less frequently than every 10 years is insufficient to assure that there is a leak-tight barrier against the controlled release of radioactivity to the environment.84 However, New York overlooks that there are numerous containment tests and inspections (not just the ILRT) performed in accordance with other plant programs that collectively provide a high degree of assurance against containment degradation.
As discussed in Section III, supra, 10 C.F.R. Part 50, Appendix J, identifies three types of required tests: Type A (ILRT), Type B, and Type C tests. Further, as stated in the LAR, Type B and C tests identify the vast majority of potential containment leakage paths.85 In fact, when the NRC revised Part 50 in 1995 to provide a performance-based option for containment leakage-rate testing, it specifically noted, based on findings contained in NUREG-1493, that Type B and C 82 See infra, pp. 16-29; see also LAR, attachment 1, at 5-13 (discussing results of IP2 tests and inspections).

tests are capable of detecting over 97 percent of containment leakages, and that of the 97 percent, virtually all leakages are identified by LLRTs of containment isolation valves (i.e., Type C tests).86 This was a key consideration in the NRCs decision to allow the ILRT performance-based option.87 In addition to leakage rate tests, Appendix J specifies that visual examinations of the accessible interior and exterior surfaces of containment structures and components be performed prior to any Type A test, and at periodic intervals between Type A tests to identify any evidence of structural deterioration that may affect either the containment structural integrity or leak tightness.88 Furthermore, the NRC Part 50 regulations mentioned above specify ISI, repair, and replacement requirements that licensees must meet with regard to reactor containment structures and associated pressure- retaining components.89 Accordingly, there is no basis for New Yorks suggestion that the ILRT is the only means by which a licensee can ensure the containments continuing structural integrity and ability to perform its intended safety function.90 Moreover, there is no basis for New Yorks apparent belief that an ILRT interval exceeding 10 years will lead to an unacceptable risk of an undetected loss of containment integrity or reduction in the margin of safety at IP2.91 Significantly, the very documents New York references in its Petition undermine its claims.92 Specifically, New York cites a number of historical documents as purported evidence 86 See Primary Reactor Containment Leakage Testing for Water-Cooled Power Reactors, 60 Fed.

for its claims regarding the alleged unique history of damaging events affecting the IP2 containment liner.93 As discussed below, those documents actually demonstrate that the 1968, 1973, and 1980 incidents cited by New York have not compromised the integrity of the IP2 containment liner.
1968 Liner Buckling: The first historical incident cited by New York occurred in 1968 during the initial construction of IP247 years ago. Specifically, during construction of the welded steel liner on the IP2 containment structure, a buckle or liner deformation was observed in the vicinity of the fuel transfer tube canal penetration.94 Plant construction specification 9321 225-3, Containment Building Liner, allowed a two-inch tolerance for local buckling.95 Field measurements taken in the buckled zone indicated two points at which the acceptable limits were exceeded by 1/8-inch and 5/16-inch, respectively.96 As stated in the January 1968 licensee-prepared report cited by New York, it was concluded that the integrity of the liner has not been violated.97 The report explains that because the liner material is highly ductile, and the liner is deflection-limited by the reinforced concrete-wall, strains in the liner will remain elastic and the leak proof integrity of the liner is maintained under all anticipated conditions.98 It further states that the engineers and constructors decided, in any case, to install a system consisting of a combination of a strongback and stud anchors to prevent additional buckling of these points under compressive loadings (by holding the liner to the 93 Petition at 7.

concrete).99 Following repair of the liner bulge, leak tests were performed on the channels in the affected area, and magnetic particle inspection was made of all weld channel fillet welds in the same area.100 The weld channel system passed the leak and magnetic-particle tests, and the liner was determined to within the allowable tolerances at all points.101 Thus, nothing in the 1968 report cited by New York indicates that the IP2 liner fails to conform with the applicable specifications or is subject to unusual stresses.102 1973 Liner Deformation: The second incident cited by New York involved slight inward deformations of portions of the IP2 containment liner above the feedwater pipe penetrations that occurred as a result of the November 13, 1973 failure of a section of the feedwater line to Steam Generator No. 22. New York references four documents in connection with this event, each of which contradicts New Yorks claims of a structurally-compromised containment liner. The first document is a November 30, 1973 letter from Consolidated Edison (Con Edison), the previous IP2 licensee, to the Atomic Energy Commission (AEC), providing supplemental information concerning the incident.103 Among other things, that letter states that: There is no visual 99 See id. at 8.

Notably, the Commissions November 1970 safety evaluation report (SER) (page 81) references the January 1968 report discussed above, and Supplement 1 to the SER (Appendix A, page 1) indicates that the NRC reviewed corrective actions related to the containment liner bulge during a site inspection.

evidence of any reduction in containment liner integrity. In addition, the weld channel penetration and pressurization system air consumption in this area of containment following the incident was normal.104 The second document cited by New York is Con Edisons Feedwater Line Incident Report - Indian Point Unit No. 2, dated January 14, 1974.105 The report notes that in response to the event, Con Edison performed a survey of the liner profile, ultrasonic testing of liner studs, magnetic particle inspection of the liner, bend tests, and pressure and leak tests.106 Importantly, the report states that throughout and subsequent to the incident, there was no evidence of any reduction in containment liner integrity, and that the weld channel penetration and pressurization system air consumption in the affected area of containment following the incident was normal.107 It further states that the results of a Type B leakage test performed following the replacement of the pipe and endplates in the Line No. 22 feedwater penetration indicated that the leakage was small and acceptable for continued service and safe operation of the facility.108 Appendix IV of the report contains a detailed analysis of the containment liner, and concludes that the integrity of the deformed liner area had not been violated by the incident.109 104 Id. at 5.

The third document referenced in the Petition is a March 12, 1974 follow-up letter from Con Edison to the AEC.110 The concluding paragraph of the letter states that, based on the results of the special liner leakage test and other tests and analyses performed on the containment liner,111 Con Edison concludes that the effects of the feedwater incident which occurred on November 13, 1973 did not impair the ability of the containment liner to perform its function and that the original acceptance criteria for containment leakage are still satisfied.112 Finally, the fourth document cited by New York is an April 15, 1974 internal AEC letter documenting the agencys regulatory evaluation of the structural portions of the January 14, 1974 Feedwater Line Incident Report.113 As reflected in this document, the AEC agreed with Con Edisons conclusion that the damage to the liner has not impaired its integrity and that it can perform its function with an adequate margin of safety.114 New York does not challenge any of the conclusions contained in the aforementioned documents. As it correctly notes, in the April 15, 1974 letter, the AEC stated that increased attention should be given to the surveillance of the liner during the life of the plant, and that the 110 See Letter from Letter from William J. Cahill, Jr., Consolidated Edison, to James P. OReilly, Atomic Energy Commission (March 12, 1974) (ML093560204).
111 As discussed in the March 12, 1974 letter, Con Edison initially had performed two special leak rate tests, during which containment pressure was increased gradually to 47 psig and stabilized at that pressure, in order to verify the containment liner integrity following the slight bulging that resulted from the feedwater incident. See id. at 1
& attachment 1. The leakage was determined to be approximately 0.029% per day of the containment free volume, which is well within both the design leakage limit of 0.1% per day and the more restrictive criterion for the test of 0.04% per day. See id. at 1. Con Edison also performed a third special leakage test with the Containment Weld Channel and Penetration Pressurization System (WC&PPS) (described in Section III.A above). The results of that test, when analyzed in conjunction with the results of the first two tests, yielded a still-acceptable leak rate of 0.034% per day. See id. at 1 & attachment 2.

frequency of the leakage tests required by the Technical Specification should be increased.115 That fact, however, does not undermine the robust technical justification for the requested ILRT interval extension contained in the LAR, including the plant-specific PRA-based risk impact assessment. The AECs recommendation regarding increased testing frequency was made over 40 years ago based on the information and technical knowledge then available to it. Unsurprisingly, since that time, the NRCs and industrys understanding of containment-related phenomena and integrated leakage rate testing has increased substantially as a result of subsequent technical studies and four decades of operating experience. Indeed, it is that enhanced understanding and additional operating experience that led the NRC to issue in 1995 a new risk-based regulation based on the performance history of components (containment, penetrations, valves) as the means to justify an increase in the interval for Type A, B, and C tests,116 and to approve one-time and permanent extensions of the ILRT interval from 10 to 15 years for various plantsincluding IP2 and IP3.117 1980 Flood-Related Corrosion: The third historical incident mentioned by New York occurred on October 17, 1980. As noted in NRC IE Information Notice No. 80-37, personnel entering the IP2 containment to make a component repair discovered that water from leaking service water pipes had accumulated on the containment floor.118 Citing the NRC Staffs safety evaluation for the 2002 license amendment that allowed a one-time extension of the IP2 ILRT interval from 10 to 15 years, New York states that this event resulted in the corrosion of the containment liner at the 46 ft. elevation, where it meets the concrete containment floor.119 115 See id., encl. at 4.

New York again ignores those portions of the document that undercut its argument. The NRC Staffs safety evaluation for the 2002 ILRT-related license amendment specifically discusses the 1980 containment flooding event.120 It notes that during the 2000 refueling outage, Entergy examined the IP2 containment liner plate in accordance with ASME Code requirements as part of an ISI program inspection.121 Specifically, Entergy performed ultrasonic testing (UT) of the liner plates near the 46 ft. elevation (containment concrete floor) to determine the extent of corrosion.122 The areas examined included all locations at which there was degradation of the moisture barrier or the concrete floor.123 The measured liner thicknesses were greater than the conservatively specified minimum liner thickness (0.34 in.) required to maintain containment pressure boundary integrity.124 Entergy also repaired the moisture barrier seal (between the concrete containment floor and the insulation mounted on the containment wall in areas where it had deteriorated) to prevent any further corrosion of the liner below the cylinder/containment floor interface.125 Based on its review of the examination results, the Staff found reasonable assurance that the examinations had identified the minimum liner thickness in the areas where the liner is most likely to have been affected by the 1980 flooding event.126 It further concluded that the structural integrity of the containment is acceptable because the remaining liner thickness is sufficient to withstand the loading associated with design-basis accident conditions.127 Also noting Entergys 120 See 2002 IP2 Safety Evaluation at 8-10, 14 (ML021860178).

planned future re-inspections of the affected areas, the Staff found the licensees approach for ensuring that the integrity of the containment liner will be maintained to be acceptable.128 In summary, insofar as it relies on Basis 1, NYS-1 fails to satisfy the criteria of 10 C.F.R.
§ 2.309(f)(1)(iv), (v) and (vi). New York fails to: (1) establish that the various historical events discussed in its Petition are material to the Staffs findings on the instant LAR; (2) provide any support for its claim that the structural integrity and intended function of the IP2 containment liner have been compromised; and (3) explain why the LAR is deficient when evaluated under the NRCs current ILRT requirements and related NRC-approved guidelines.
- 2. Basis 2: Alleged Insights from Previous Tests and Inspections Despite the contrary evidence discussed above, New York asserts that more recent inspections of the IP2 containment surfaces, including the containment liner, confirm that the liner and related surfaces have been harmed by the historical accidents.129 For example, citing the 2002 NRC safety evaluation report discussed above, New York states that visual and UT inspections of the liner plate conducted during the 2000 refueling outage revealed coating deterioration and corrosion.130 It further states that during IWE inspections performed in 2008, 2012, and 2014, inspectors observed general surface corrosion, minor coating peeling/flaking, blistered paint, as well as loose or buckling stainless steel insulation panels.131 New York posits that because the last ILRT was performed in 2006, it is unknown whether the indications observed in these visual inspections would result in the failure of an ILRT.132 128 Id. at 9.

As an initial matter, it bears emphasis that the limited surface corrosion and conditions cited by New York were identified during IWE visual inspections, the frequency of which is unaffected by the LAR. In addition, New York fails to explain why or how any of the observed conditions could result in the failure of an ILRT.133 Finally, New Yorks arguments again are belied by the supporting evidence on which it purports to rely. As discussed above, the NRC Staffs 2002 safety evaluation report concluded that the structural integrity of the containment liner is acceptable despite some observed liner corrosion.134 The later (i.e., 2008, 2012, and 2014)
IWE inspections are specifically discussed in Entergys LAR, which contains the following uncontroverted findings and conclusions:
Refueling Outage 2R18 (2008) Containment Inservice Inspection: The general surface corrosion, minor coating peeling/flaking, and blistered paint were previously identified and evaluated. These conditions were a repeat of previous inspections and were minor with no change and therefore acceptable. The condition of the buckling locations and looseness on the VC liner plate insulation (columns 10 and 11 elevation 68 feet) was documented in the Corrective Action Program as Condition Report CR-IP2-2008-01892. Civil Engineering performed an inspection of the stainless steel insulation jacket and has determined that all but two of the insulation jacket issues are acceptable. The two areas not acceptable were repaired during 2R18 outage.135 Refueling Outage 2R20 (2012) Containment Inservice Inspection: All of the conditions noted during this inspection did not result in any structural degradation that adversely affects the ability of the containment to perform its design function of maintaining integrity during accident conditions.136 Refueling Outage 2R21 (2014) Containment Inservice Inspection: Most of the findings were a repeat of previous inspections and were minor with no change and therefore acceptable. All non-destructive examination (NDE) reports were accepted during the 2014 containment inspection therefore no condition reports were generated.137 133 Id. at 19.

New York also cites the results for the five ILRTs discussed in the LAR, as performed between August 1979 and April 2006.138 Quoting an NRC Staff RAI issued to Entergy on April 28, 2015, New York states that As found Leakage measured during the five ILRTs is on a continuous trend towards eclipsing the IP2 Technical Specification 5.5.14.d.1 leakage rate acceptance criteria of 0.75La (i.e., 0.075 percent containment air weight per day).139 Based on simple extrapolation of the data, New York states that the expected leakage rate for an ILRT conducted in 2016 would be 0.078, exceeding the current Technical Specifications leakage rate acceptance criteria of = 0.75La.140 That argument also lacks adequate support and fails to raise a genuine dispute on a material issue of fact or law.141 New York must do more than rest on the mere existence of RAIs as a basis for [its] contention,142 because the issuance of an RAI does not alone establish deficiencies in the application, or that the NRC Staff will go on to find any of the Applicants clarifications, justifications, or other responses to be unsatisfactory.143 Indeed, in CLI-15-8, the Commission recently reiterated that RAIs are a routine means for the Staff to ask for clarification or additional corroborating information from an applicant.144 They reflect follow-up 138 See Petition at 16-17.

questions, an ongoing dialogue between the Staff and applicant.145 As such, [r]arely will pointing to an RAI, without more, suffice as support for an admissible contention.146 In any case, a contention alleging an error or omission in an application must establish some significant link between the claimed deficiency and protection of the health and safety of the public or the environment.147 In other words, the petitioner must make at least a minimal demonstration that the application under review fails to meet a statutory or regulatory requirement.148 New York has not done so here through its reference to the Staffs RAI and simple extrapolation of the five available ILRT data points.
Specifically, as reflected in the LAR and further explained in Entergys June 8, 2015 response to the NRC Staffs RAI, all five of the ILRTs conducted at IP2 between August 1979 and April 2006 have satisfied the as-found leakage acceptance criterion of 1.0La, as specified in IP2 Technical Specification 5.5.14.149 This demonstrates that the overall containment leakage (Type A, Type B and Type C) has been maintained at leakage rates less than the assumed leakage rate in the plant accident analysis.150 Thus, Entergy does not believe that the IP2 Type A ILRT test 145 Id.

results since August 1979 indicate that the IP2 containment is degrading or constitutes an adverse trend requiring corrective action.151 Furthermore, even if the next as-found leakage is determined to be 0.78La, which New York predicts for an ILRT performed in 2016 based on its extrapolation of the current data, that value still will be less than the applicable as found acceptance criterion of 1.0La. In fact, even if the data are extrapolated to 2021 using New Yorks approach, the resulting as-found leakage rate value would be 0.85La, which still is less than the acceptance criterion of 1.0La.152 Importantly, if the measured as-found leakage exceeded 1.0La, then Unit 2 could not resume operations, and Entergy would need to take appropriate corrective actions, including more frequent testing.153 In addition, the IP2 Containment Leakage Rate Testing Program requires that the as left criterion of 0.75La be met prior to plant restart, to ensure that there is sufficient margin to accommodate potential degradation that could increase the containment leakage rate before the next ILRT is performed.154 Thus, in view of the above, New York has not shown that 151 See id.

The performance criterion for Type A tests is a performance leakage rate (as defined in this guideline) of less than 1.0La. Type A testing shall be performed at a frequency of at least once per 15 years. If the Type A performance leakage rate is not acceptable, the performance criterion is not met, and a determination should be performed to identify the cause of unacceptable performance and determine appropriate corrective actions. Once completed, acceptable performance should be reestablished by demonstrating an acceptable performance leakage rate during a subsequent Type A test before resuming operation and by performing another successful Type A test within 48 months following the unsuccessful Type A test.
Following these successful Type A tests, the surveillance frequency may be returned to at least once per 15 years.

- 3. Basis 3: Alleged Effect of the Elevated Seismic Hazard Referring to ongoing analyses done in connection with the NRCs various post-Fukushima initiatives, New York accuses Entergy of ignoring recent updates indicating elevated seismic hazards at the Indian Point site and not adequately considering the risk that the degraded containment liner and related containment systems and components will fail as a result of seismic activity at IP2.156 Specifically, New York states that new, revised seismic curves show that the anticipated ground motion is larger for higher frequency events than was understood when IP2 received its operating license in 1973,157 and this has led the NRC Staff to designate IP2 as Priority Group 1 plant for purposes of the NRCs and industrys ongoing Fukushima-related seismic hazard re-evaluations.158 Basis 3 is not adequately supported and fails to explain why the LAR suffers from any defect, much less a material defect warranting further exploration by the Board.159 To begin with, New York ignores the NRCs unequivocal statement, in the May 21, 2014 NRC internal memorandum cited by New York, that the NRC considered the re-evaluated hazard and previous estimates of plant capacity to conclude that this plant is safe to continue operating while 155 Indian Point, 68 NRC at 187 (stating that the NRCs contention admissibility rules require a petitioner to make at least a minimal demonstration that the application fails to meet a statutory or regulatory requirement).

additional evaluations are conducted.160 Consequently, there has been no change to the IP2 seismic design basis as a result of the ongoing seismic re-evaluation. Thus, there is no basis for New Yorks apparent belief that the IP2 containment structure and liner are somehow now more susceptible to seismically-induced failure that could lead to an unacceptable radiological release.
Additionally, if a petitioner believes that an application does not adequately address a relevant issue, then the petitioner must explain why the application is deficient.161 New York has not done so here. Citing pages of 5-26 to 5-31 of the confirmatory risk analysis submitted by Entergy in support of the LAR, New York merely avers that [t]he LAR does not address these new seismic data.162 It makes no attempt to explain why the new seismic data are relevant to the ILRT LAR or associated risk analysis; how, if at all, they might be considered within the context of those documents; and what impact, if any, they might have on the risk analysis results.163 Given that the IP2 seismic design basis has not changed as a result of the new, revised seismic curve, there is no basis for including the new seismic data in the LAR risk impact evaluation.

- 4. Basis 4: Alleged Existence of Significant Hazards Consideration New York further asserts that, contrary to Entergys and the NRC Staffs conclusions, the LAR poses a significant hazard consideration under 10 C.F.R. § 50.92(c).165 New York makes two arguments in support of that assertion. First, it claims that the requested ILRT interval extension increases the consequences of a release of radiation from the reactor, since any such release might escape containment and reach the environment and citizens of the State in amounts that exceed NRC safety standards.166 Second, New York claims that the LAR involves a significant reduction in a margin of safety under 10 C.F.R. § 50.92(c)(3) because reducing the frequency of ILRTs necessarily reduc[es] the margin of safety for containment integrity.167 Basis 4 fails to support the admission of NYS-1 for multiple reasons. As a threshold legal matter, 10 C.F.R. § 50.58(b)(6) explicitly bars the type of challenge raised by New York here. It states: No petition or other request for review of or hearing on the Staffs significant hazards consideration determination will be entertained by the Commission.168 As stated in the Hearing Notice, the NRC reviewed Entergys significant hazards consideration analysis in the LAR, and concluded that the standards of 10 C.F.R. § 50.92(c) are satisfied.

determine that the amendment request involves no significant hazards consideration.169 As another licensing board noted recently noted, [a] no significant hazards consideration determination is a procedural decision barred from litigation pursuant to 10 C.F.R. § 50.58(b)(6) and licensing board precedent.170 Accordingly, Petitioners argument is outside of the Boards jurisdiction, and is not subject to challenge in this proceeding.171 Even assuming New Yorks challenge to the Staffs proposed no significant hazards consideration determination was procedurally permissible (which it is not), the challenge is devoid of factual or technical support. In short, New York relies solely on speculation by counsel and claims that Entergy already has shown above to be groundless, viz., the alleged unique degradation history of the IP2 containment liner (including wear and degradation observed during more recent tests and inspections);172 the IP2 containments trending towards failing an ILRT by 2016;173 and the purportedly elevated seismic hazards at the Indian Point site.174 Further, New York fails to controvert any aspect of Entergys no significant hazards consideration analysis (as contained in the LAR and described in the Hearing Notice), which contains a number of key technical points that undermine various claims made by New York in its Petition:

The proposed amendment does not involve a physical change to the plant (i.e., no new or different type of equipment will be installed) or a change to the manner in which the plant is operated or controlled. Nor does it alter the manner in which safety limits, limiting safety system setpoints, or limiting conditions for operation are determined.175 The containment itself and the testing requirements to periodically demonstrate the integrity of the containment exist to ensure the plants ability to mitigate the consequences of an accident and do not involve any accident precursors or initiators.176 The proposed amendment adopts the NRC-accepted guidelines of NEI 94-01, Revision 2A, for development of the IP2 performance-based testing program for the Type A testing.
The specific requirements and conditions of the Containment Leakage Rate Testing Program, as defined in the Technical Specifications, ensure that the degree of primary containment structural integrity and leak-tightness that is considered in the plants safety analysis is maintained.177 Entergys confirmatory risk assessment using the IP2 PRA model concludes that extending the ILRT test interval from ten years to 15 years results in a very small change to the risk profile. Further, Entergy has determined that the increase in conditional containment failure probability due to the proposed change would be very small.178
- 5. Basis 5: Alleged Reliance on Erroneous Information from the IP2 License Renewal SAMA Analysis New York claims that the LAR is deficient because it purportedly relies on certain information obtained from the SAMA analysis prepared as part of the IP2 license renewal application.179 New York assertsagain without reference to any supporting technical analysis or expert opinionthat the SAMA analysis omits important considerations and contains erroneous assumptions and inputs that work to undercount the costs of an offsite radiation release and therefore skew the cost benefit analysis in favor of the requested amendment.180 In particular, it claims that the SAMA analysis: (1) does not take into account the value or decontamination cost of offsite properties with iconic value, natural resources, or critical infrastructure; (2) artificially 175 See LAR, attachment 1, at 17-18.

and improperly limits its scope to land and population only within 50 miles of the site; and (3) relies on an outdated dollar per person-rem value of $2,000.181 Basis 5 does not support NYS-1 because it fails to provide an adequately supported and reasoned statement of why the LAR is unacceptable in some material respect.182 First, New York provides nothingno credible facts, supporting references, or expert opinionto support its statements regarding the license renewal SAMA analysis. Second, it fails to establish any nexus between its (unsubstantiated) criticisms of the license renewal SAMA analysis and the contents of the LAR, particularly the risk impact assessment.
Entergy can discern no such nexus given the vagueness of New Yorks claims and its failure to explain with particularity how those claims relate to the assumptions and methods actually used in the risk impact assessment. Insofar as the risk impact assessment discusses the IP2 license renewal SAMA analysis, it makes the following points:
External events were accounted for in the risk impacts analysis based on the available information from the IP2 IPEEE, as reported and used in the license renewal SAMA analysis; i.e., the external events CDF contribution values used in the risk impact assessment for the relevant external event initiator groups (seismic, internal fire, high winds) are consistent with those used in the SAMA analysis.183 Since the most current external events models for IP2 and IP3 are those embodied in the IPEEE, a multiplier was applied to the internal events results based on the IPEEE, similar to that used in the SAMA analysis.184 Dose results for the containment failures modeled in the PRA can be characterized by information that was prepared to support the license renewal SAMA analysis. This information was supplemented with revised calculations for the base case containment intact scenarios, which are critical for use in the ILRT extension assessment.185 181 Id. at 20.

The use of the projected 2035 population to estimate population dose within a 50-mile radius of the plant for various release categories is consistent with the approach used in the license renewal SAMA analysis.186 It is entirely unclear how New Yorks vague claims regarding the economic value of iconic properties, distance truncation, and the $2,000 per person-rem value relate to, much less directly challenge, the assumptions and methodologies described in the risk impact assessment.
- 6. Basis 6: Entergys Alleged Desire to Reduce Costs and Maximize Revenues to the Detriment of Plant Safety New York asserts that Entergys desire to reduce costs and maximize revenues does not justify rolling back this important safety-related test.187 It bases this claim on Entergys statement in the LAR that [t]he performance of fewer ILRTs would result in significant savings in radiation exposure to personnel, cost, and critical path time during future refueling outages.188 New York further states that reduced costs and outage times are not relevant to the NRCs review of the LAR or adequate protection findings, and do not justify exposing millions of State citizens and the State environment to exposure from radiation escaping from a damaged containment structure.189 population dose runs for the intact containment scenarios, and the Level 2 PRA containment failure release frequencies. See id. at 5-6.
186 See id. at 3-1. In a related vein, New York criticizes Entergys reliance (in the risk impact assessment) on NUREG-1493, noting that the representative pressurized water reactor (PWR) considered in that study was the Surry reactor, located in rural Virginia. According to New York, it is wholly inappropriate to use Surry as a benchmark plant and site for regulatory analysis in a license amendment for IP2, which is located in a densely populated urban and suburban environment and has been subjected to various unique degradation events.
Petition at 19. This argument is factually groundless, and fails to recognize the manner in which the IP2 ILRT risk impact assessment was performed. Specifically, that assessment makes use of plant-specific Level 1 and Level 2 PRA information (e.g., initiating events, accident sequences, source terms and release frequencies) as well as Indian Point region-specific population data. The fact that NUREG-1493 used Surry as a representative PWR plant is wholly irrelevant to Entergys LAR and the detailed plant-specific technical justification set forth therein.

New Yorks assertions are both factually groundless and irrelevant. Nowhere in the LAR does Entergy cite reduced costs or outage times as justification for the requested 5-year extension of the ILRT interval. It simply notes that reduced radiation exposure to personnel, costs, and outage lengths are expected to result from an increased ILRT interval.
Notably, when Entergy sought an identical ILRT interval extension for IP3 last year, New York made similar statements in comments on the associated license amendment request. As documented in its March 13, 2015 safety evaluation, the NRC Staff rejected New Yorks claim that Entergys references to reduced costs were legally impermissible.190 The Staff explained that when the Commission issued the rules allowing licensees to request performance-based containment leak rate testing, it noted its expectation that licensees likely would save money by using the performance-based option.191 Therefore, the Staff further noted, Entergys statement that it expected to save money is congruent with the Commissions expectations.192 The Staff then emphasized that although cost-saving may result from the Commissions rules, cost is not a factor to be considered under 10 C.F.R. § 50.57(a), 10 C.F.R. § 50.54(o), or Appendix J to 10 C.F.R. Part 50, or in considering any related license amendment request.193 The Staff noted that New Yorks concerns should be assuaged in light of these facts.194 In summary, insofar as NYS-1 relies on Basis 6, it lacks adequate support, fails to raise a genuine dispute on a material issue of fact or law, and fails to directly challenge some material aspect of the application. Therefore, it is inadmissible under 10 C.F.R. § 2.309(f)(1)(iv)-(vi).

C. Proposed Contention NYS-2 Is Inadmissible Because It Fails to the Meet the Requirements of 10 C.F.R. § 2.309(f)(1)(iii)-(vi)
In NYS-2, New York asserts that Entergy and the NRC Staff must perform an environmental review of the LAR under NEPA.195 In short, New York argues that, contrary to Entergys and the Staffs conclusions, the LAR poses a significant hazard consideration under 10 C.F.R. § 50.92(c).196 It further asserts that because the LAR (purportedly) involves a significant hazards consideration, it does not qualify for the categorical exemptions from environmental review under 10 C.F.R. § 51.22(c)(9), and that under 10 C.F.R. § 51.101(a)(1), the Commission cannot act on the LAR until an environmental review is complete.197 NYS-2 must be rejected as inadmissible because it constitutes a second impermissible challenge to the NRC Staffs proposed no significant hazards determination. Indeed, New York incorporates by reference the same arguments presented in support of Basis 4 of NYS-1.
Accordingly, NYS-2 should be rejected for the same reasons discussed above (see supra, pages 31-33). In short, 10 C.F.R. § 50.58(b)(6) and related precedent bar adjudicatory challenges to the Staffs no significant hazards consideration determination. Inasmuch as New York challenges that determination and contends that an environmental review of the LAR is required by NEPA, it also improperly challenges 10 C.F.R. § 50.58(b)(6) and 10 C.F.R. § 51.22(c)(9) (which categorically excludes amendments or exemptions involving no significant hazards consideration from an environmental review under NEPA and 10 C.F.R. Part 51). A contention that challenges an NRC rule is outside the scope of the proceeding because, absent a waiver, no rule or regulation of the Commission . . . is subject to attack . . . in any adjudicatory proceeding.198 Finally, as discussed 195 Petition at 20.

above, New Yorks objections to the Staffs proposed no significant hazards consideration determination lack factual and technical support. Moreover, they are inconsistent with numerous other no significant hazard consideration determinations made by the Staff in its previous approvals of permanent and one-time extensions of plant ILRT intervals from 10 to 15 years.199 Accordingly, NYS-2 raises an issue that is outside the scope of this proceeding, contrary to 10 C.F.R. § 2.309(f)(1)(iii). The contention also fails to raise a material issue, lacks legal or factual support, and fails to demonstrate that a genuine dispute exists on a material issue of law or fact. As such, it also is inadmissible under 10 C.F.R. § 2.309(f)(1)(iv), (v), and (vi).
V. CONCLUSION As demonstrated above, New York has not proffered a contention that satisfies the contention admissibility requirements in 10 C.F.R. § 2.309(f)(1). Therefore, the Board should reject New Yorks Petition in its entirety.

However, as New York has not petitioned for a waiver of any NRC regulation, this process need not be discussed further.

(Entergy) submits this answer opposing the petition to intervene and request for hearing filed on May 18, 2015, by the State of New York (New York or Petitioner).1 New York seeks to intervene in the proceeding associated with Entergys December 9, 2014, license amendment request (LAR), which seeks to revise Indian Point Unit 2 (Unit 2 or IP2) Technical Specification 5.5.14, Containment Leakage Rate Testing Program, to extend the frequency of the Containment Integrated Leak Rate Test (ILRT) or Type A Test for Unit 2 from once every 10 years to once every 15 years on a permanent basis.2 New York proffers two proposed contentionsa safety contention (NYS-1) and an environmental contention (NYS-2).3 For the reasons set forth below, the Atomic Safety and Licensing Board (Board) should deny the Petition in its entirety. Although Entergy does not contest New Yorks standing to 1 State of New York Petition to Intervene and Request for Hearing (May 18, 2015) (Petition) (ML15138A415). 2 See Letter from Lawrence Coyle, Entergy, to NRC Document Control Desk, NL-14-128, Proposed License Amendment Regarding Extending the Containment Type A Leak Rate Testing Frequency to 15 years, Indian Point Unit Number 2, Docket No. 50-247, License No. DPR-26 (Dec. 9, 2014) (LAR) (ML14353A015). 3 Petition at 5, 20.
intervene in this proceeding,4 New York has failed to submit an admissible contention. The deficiencies in New Yorks proposed contentions are many, but perhaps the most obvious defect is New Yorks failure to provide any expert opinion or relevant technical information to support its overarching claim that issuance of the requested license amendment will imperil New Yorks citizens and environment. As discussed herein, New York provides no valid factual or technical support for that claimamong many otherscontrary to the requirements of 10 C.F.R. § 2.309(f)(1)(v).5 Contrary to the requirement of 10 C.F.R. § 2.309(f)(1)(vi), New York also fails to directly challenge the contents of Entergys license amendment application,6 which contains a detailed technical evaluation of the proposed extension of the interval for the primary containment ILRT from 10 to 15 years.7 That evaluation is supported by a detailed, plant-specific risk impact assessment that was prepared by a qualified probabilistic risk assessment (PRA) vendor, which concluded that increasing the ILRT interval on a permanent basis to a one-in-fifteen year frequency is not considered to be significant since it represents only a small change in the IP2 risk profiles.8 New York ignores these technical evaluations, and instead relies principally on 4 See Petition at 2-4. New York includes a list of historic, unique or otherwise significant sites within 50 miles of the IP2 site as Attachment 1 to its Petition, and a map of reservoirs in the vicinity of the IP2 site as Attachment
- 2. Insofar as New York appears to have included those attachments to support its claim of standing, which Entergy does not dispute, Entergy does not further discuss the attachments, which have no apparent nexus to the ILRT-related subject matter of Entergys pending license amendment request.

conclusory assertions by counsel and discussion of historical containment-related incidents that occurredand were addressed35 years or more ago.9 New York also overlooks the fact that the ILRT is only one of numerous tests and inspections that Entergy performs to ensure that the IP2 containment performs its intended safety function. As discussed in the LAR and Section III below, in addition to the Type A tests (ILRTs), Entergy performs: (1) Type B tests for the containment penetrations and airlocks, (2) Type C tests for the containment isolation valves, (3) IWE internal visual inspections of the containment liner every three and one-third years, (4) IWL external visual inspections of the containment concrete surfaces every five years, (5) general visual inspections of the outside surfaces of the containment (including the penetrations) every two years per plant procedure 2-PI-2Y001, and (6) general visual inspections of the internal and external containment surfaces prior to each ILRT and at a periodic interval between tests based on the performance of the containment system. As further discussed in Section III, IP2 has a weld channel pressurization system that allows for real-time monitoring of potential leakage through the portions of the containment boundary that it pressurizes. None of these other tests, inspections, or systems is affected by the requested change to the ILRT frequency. Finally, New Yorks proposed contentions raise issues that are neither within the scope of this LAR proceeding nor material to the Staffs required findings, contrary to the requirements of 10 C.F.R. § 2.309(f)(1)(iii) and (iv). In particular, New York raises issues related to the Indian Point license renewal severe accident mitigation alternatives (SAMA) analysis and improperly 9 See, e.g., Petition at 1 (Entergys LAR would increase the risk that the citizens and environment of the State will be exposed to the release of radioactive materials.); id. at 12 (The history of the IP2 containment liner makes it particularly ill-suited for the reduced safety-margins proposed by Entergy.). These, like many statements in the Petition, are unaccompanied by citations. Moreover, as discussed herein, insofar as New York discusses specific supporting documents in its Petition, it repeatedly takes statements out of context and ignores other material information in those documents that contradicts its position. 3
challenges the Nuclear Regulatory Commission (NRC or Commission) Staffs proposed no significant hazards consideration determination for the LAR.10 For all these reasons, the Petition should be denied in its entirety. II. PROCEDURAL HISTORY On December 14, 2014, Entergy filed with the NRC an application to amend the IP2 operating license pursuant to 10 C.F.R. § 50.90. The proposed amendment would revise Technical Specification 5.5.14, Containment Leakage Rate Testing Program, to extend the frequency of the ILRT from once every 10 years to once every 15 years on a permanent basis.11 As discussed in Section III.E of this brief, the NRC approved a license amendment that extended the Unit 2 ILRT interval on a one-time basis from ten years to 15 years in August 2002. In recent years, the NRC has approved numerous one-time and permanent extensions of the ILRT interval from 10 to 15 years for various plants based on the performance-based NRC regulations and NRC-approved industry guidelines (i.e., topical reports) discussed below.12 Entergys application contains a detailed technical evaluation (Attachment 1) of the proposed Technical Specification changes, which are in accordance with 10 C.F.R. Part 50, Appendix J, and the NRC-approved guidance document NEI 94-01, Rev. 2-A, Industry Guideline for Implementing Performance Based Option of 10 CFR Part 50, Appendix J (Oct. 2008). Among other things, the LAR evaluation discusses the safety significance of the proposed Technical Specification change in accordance with the criteria of 10 C.F.R. § 50.92 (Issuance of 10 See Petition at 8-9, 19-22. 11 See LAR at 1. 12 Examples of previous NRC-approved ILRT interval extensions include Nine Mile Point, Unit 2 (permanent extension of ILRT interval from 10 to 15 years in 2010 (ML100730032)); Arkansas Nuclear One, Unit 2 (permanent extension of ILRT interval from 10 to 15 years in 2011 (ML110800034)); Palisades (permanent extension of ILRT interval from 11.25 to 15 years in 2012 (ML120740081)); Indian Point, Unit 3 (permanent extension of ILRT interval from 10 to 15 years in 2015 (ML15028A308)); Braidwood, Units 1 and 2 (one-time extension of ILRT amendment from 10 to 15 years in 2008 (ML080640290));Limerick, Units 1 and 2 (one-time extension of ILRT amendment from 10 to 15 years in 2008 (ML080310769)); and North Anna, Unit 2 (one-time extension of ILRT amendment from 10 to 15 years in 2008 (ML081510562)). 4
Amendment).13 Entergy determined that the proposed amendment does not involve a significant hazards consideration under 10 C.F.R. § 50.92(c).14 In addition, the application includes a detailed confirmatory risk impact assessment (Attachment 3) that evaluates the risk associated with implementing a permanent extension of the ILRT interval from 10 years to 15 years.15 The impact assessment demonstrates that increasing the ILRT interval is not risk significant because it represents only a small change in the IP2 plant-specific risk profile.16 The NRC accepted the LAR for docketing, and published a Hearing Notice on March 17, 2015.17 The Hearing Notice included the NRC Staffs proposed no significant hazards consideration determination and provided interested parties 60 days (i.e., until May 18, 2015) to request a hearing related to the LAR.18 New Yorks Petition was filed on May 18, 2015. As noted above, the Petition contains a proposed safety contention (NYS-1) and a proposed environmental contention (NYS-2). In brief, NYS-1 alleges that Entergys LAR fails to demonstrate that it complies with 10 C.F.R. §§ 50.40 and 50.92 or 10 C.F.R. Part 50, Appendix J, and therefore does not provide reasonable assurance of adequate protection for the public health and safety, as required by the Atomic Energy Act of 13 See LAR, attachment 1 at 17-18. 14 Id. at 18. 15 See id., attachment 3. Entergy third-party vendor ERIN Engineering & Research, Inc. prepared the risk impact assessment in accordance with NRC-approved industry guidelines discussed in Section III below. See id. at 1-1. 16 See id. at 7-2. This conclusion is consistent with the general findings of previous NRC and industry studies that the risk impact associated with extending the ILRT interval to one in 15 years is small. See LAR, attachment 1, at 15. 17 Biweekly Notice; Applications and Amendments to Facility Operating Licenses and Combined Licenses Involving No Significant Hazards Considerations, 80 Fed. Reg. 13,902 (Mar. 17, 2015) (Hearing Notice). 18 See id. at 13,903, 13,905-06. The NRCs no significant hazards consideration determination is consistent with the NRCs very recent approval of an amendment to the Indian Point Unit 3 (IP3) operating license allowing a permanent extension of the Type A primary containment ILRT frequency from once every 10 years to once every 15 years. See Letter from Douglass V. Picket, NRC, to Vice President of Operations, Entergy, Indian Point Nuclear Generating Unit No. 3 - Issuance of Amendment Re: Extension of the Type A Containment Integrated Leak Rate Test Frequency from 10 to 15 Years (TAC No. MF3426) (Mar. 13, 2015) (ML15028A308). 5
1984, as amended (AEA).19 NYS-2 asserts that proposed license amendment is not categorically exempt from environmental review under 10 C.F.R. § 51.22(c)(9), and that Entergy and the NRC Staff must perform an environmental review to meet the requirements of the National Environmental Policy Act (NEPA).20 Entergy timely files this answer opposing the Petition in accordance with 10 C.F.R. § 2.309(i)(1). III. REGULATORY BACKGROUND A. Safety Function of the IP2 Containment Structure The IP2 containment structure is a steel-lined reinforced concrete vertical cylinder with a flat base mat and hemispherical dome that completely encloses the reactor and reactor coolant system (RCS).21 The containment liner, which covers the inner surface of the concrete containment structure, provides an essentially leak-tight barrier against leakage out of the containment during an accident.22 The containments intended function is to ensure that any leakage of radioactive materials to the environment, even if a gross failure of the RCS were to occur, does not result in off-site doses greater than the limits of 10 C.F.R. Part 100.23 The IP2 containment pressure boundary consists of the steel-lined containment structure, containment access penetrations, and other process piping and electrical penetrations.24 19 Petition at 5. 20 Id. at 20. 21 See Letter from Patrick D. Milano, NRC, to Michael, R. Kansler, Entergy, Indian Point Nuclear Generating Unit No. 2 - Amendment Re: One-Time Deferral of Containment Integrated Leak Rate Test (TAC No. MB2414), encl. 2, Safety Evaluation by the Office of Nuclear Reactor Regulation Related to Amendment No. 232 to Facility Operating License No. DPR-26, Entergy Nuclear Operations, Inc., Indian Point Nuclear Generating Unit No. 2, Docket No. 50-247 (Aug. 5, 2002) (2002 IP2 Safety Evaluation), at 4 (ML021860178). 22 The containment liner is carbon steel. Therefore, the only credible degradation mechanism is general corrosion caused by continuous exposure of the steel to a corrosive environment. 23 See 2002 IP2 Safety Evaluation at 4. 24 See id. 6
IP2 is one of a very few U.S. plants to have a system that pressurizes the containment weld channels and certain containment penetrations during normal plant operation.25 Specifically, the IP2 Containment Weld Channel and Penetration Pressurization System (WC&PPS) keeps the channels pressurized during normal plant operation and, by design, during accidents.26 The pressure is maintained at or above calculated peak containment accident pressure. The WC&PPS provides for continuous on-line measuring of leakage through the portions of the containment boundary that it pressurizes, and thereby also allows plant operators to promptly detect increased leakage during normal operation (e.g., in the unlikely event that a through-wall flaw develops or an isolation valve fails open).27 The WC&PPS also prevents containment atmosphere from leaking out of the containment through the liner welds and penetrations, even with a failure, during a postulated accident.28 In this regard, the WC&PPS is an engineered safety feature that would act to prevent containment leakage through potential flaws in the liner welds.29 B. Applicable NRC Requirements, Including Required Leakage Tests To ensure that reactor containments are maintained properly and able to perform their design-basis functions, NRC regulations require that licensees conduct leakage rate testing and inspections of containments and associated pressure-retaining components at periodic intervals.30 Under 10 C.F.R. § 50.54(o), primary reactor containments are subject to the leakage testing requirements contained in 10 C.F.R. Part 50, Appendix J, Primary Reactor Containment Leakage 25 See id. at 5. 26 See id. 27 See id. IP2 Technical Specification 3.5.16 requires the system to be operable in modes above cold shutdown and places a limit on the total rate of leakage out of the WC&PPS during normal operation. Id. If the leakage rate exceeds the limit, then Entergy must reduce the leakage rate below the limit or shut down the plant. Id. Very limited portions of the WC&PPS system (approximately 4% of the total number of penetrations/weld channels supplied with Weld Channel air) have been retired in place. 28 See id. 29 See id. 30 See id. at 2. 7
Testing for Water-Cooled Power Reactors. Appendix J identifies three types of required tests:31 (1) Type A (ILRT) tests, which measure the containment overall integrated leakage rate;32 (2) Type B local leakage-rate tests (LLRTs), which detect local leaks and measure leakage across pressure-containing or leakage limiting boundaries (other than valves) for containment penetrations; and (3) Type C LLRTs, which measure containment isolation valve leakage.33 The instant LAR, if approved, would modify only the Type A testing interval. The Type B and Type C testing intervals would not change. In addition, the frequencies of the general visual inspections discussed in Section III.F will not change. C. Appendix J Test Program Option B and Related NRC-Approved Guidance In 1995, the NRC amended Appendix J to provide a performance-based Option B for the containment leakage testing requirements.34 Option B allows for test intervals for Type A, Type B, and Type C testing to be determined by using a performance-based approach.35 Performance-based test intervals are based on consideration of a components operating history failure risk.36 If selected, Appendix J, Option B requires that a Type A test be conducted at a periodic interval based on historical performance of the overall containment system.37 31 See 10 C.F.R. pt. 50, app. J, Option B, secs. III.A. & III.B. 32 See id. sec. III.A. The Type A test or ILRT measures integrated leakage rate from all potential leakage paths, including containment liner welds, valves, fittings, and components that penetrate containment. See 2002 IP2 Safety Evaluation at 2. These tests typically involve pressurizing the containment atmosphere to a specified test pressure for a duration that is sufficient to determine what the containment leakage would be under design-basis accident conditions. See id. The acceptance criteria for the Type A test and the Technical Specification leakage limits are conservatively established to ensure that, in the event of a design-basis accident, the dose received by a member of the general public will not exceed the limits specified in 10 C.F.R. Part 100. See id. 33 10 C.F.R. pt. 50, app. J, Option B, sec. III.B. 34 Final Rule, Primary Reactor Containment Leakage Testing for Water-Cooled Power Reactors, 60 Fed.

Current IP2 Technical Specification 5.5.14 states that leakage rate testing shall be performed as required by Option B, as modified by approved exemptions, and in accordance with the guidelines contained in NRC Regulatory Guide 1.163.38 Regulatory Guide 1.163 endorses Nuclear Energy Institute (NEI) Report 94-01, Revision 0,39 which NEI has since revised several times in response to subsequent developments and NRC-industry interactions, including NRC Staff requests for additional information (RAIs).40 Revision 2-A of NEI 94-01 added guidance for extending Type A ILRT surveillance intervals beyond ten years. NEI 94-01, Revision 2-A, the revision referenced in the LAR, states that plant-specific confirmatory analyses are required when extending the Type A ILRT interval beyond ten years.41 Section 9.2.3.4 of NEI 94-01 states that the assessment should be performed using the approach and methodology described in Electric Power Research Institute (EPRI) Technical Report (TR) 1009325, Revision 2-A, Risk Impact Assessment of Extended Integrated Leak Rate Testing Intervals.42 The analysis is to be performed by the licensee and retained in the plant documentation and records as part of the basis for extending the ILRT interval. In a safety evaluation issued on June 25, 2008, the NRC Staff found the methodology in NEI 94-01, Revision 2, and EPRI TR-1009325, Revision 2, to be acceptable for referencing by licensees proposing to 38 See LAR, attachment 2; NRC Regulatory Guide 1.163, Performance-Based Containment Leak-Rate Testing Program (Sept. 1995) (ML003740058). 39 NEI 94-01, Rev. 0, Industry Guideline for Implementing Performance Based Option of 10 CFR Part 50, Appendix J (July 1995) (ML11327A025). 40 NEI submitted NEI 94-01, Revision 1 to the NRC in December 2005, and Revision 2 in August 2007. The NRC Staff approved Revision 2 as a topical report in a safety evaluation issued on June 25, 2008. At the Staffs request, NEI issued an NRC-approved version as NEI 94-01, Rev. 2-A in October 2008.

amend their licenses to permanently extend the ILRT interval to 15 years, provided that certain conditions set forth in Section 4.2 of the NRC Staffs safety evaluation are satisfied.43 D. Leakage Rate Test Acceptance Criteria The acceptance criteria for containment leakage rate tests are typically expressed in terms of the maximum allowable containment leakage rate, La, which would occur at the calculated peak containment internal pressure related to the design-basis loss-of-coolant accident (LOCA).44 Plant Technical Specifications typically specify values for La in terms of the allowable weight percent of the containment atmosphere that may leak in 24 hours at the peak containment internal pressure (Pa).45 The acceptance criteria for Type A tests, and the combined Type B and Type C tests, are typically specified as multiples of La.46 The IP2 maximum allowable containment leakage rate and leakage test acceptance criteria are specified in the plant Technical Specifications.47 The maximum allowable containment leakage rate (La) is 0.1 weight percent per day of the containment steam air atmosphere (at 47 pounds per square inch gauge (psig) and 271 degrees Fahrenheit (°F)).48 The as-found ILRT acceptance criterion is 1.0La, and the as-left ILRT acceptance criterion is 0.75La.49 The five Type A (ILRT) tests performed at IP2 all have been successful; i.e., met the as-found acceptance criterion of 1.0La.50 43 See Final Safety Evaluation by the Office of Nuclear Reactor Regulation, Nuclear Energy Institute (NEI) Topical Report (TR) 94-01, Revision 2, Industry Guideline for Implementing Performance-Based Option of 10 CR Part 50, Appendix J and Electric Power Research Institute (EPRI) Report No. 1009325, Revision 2, August 2007, Risk Impact Assessment of Extended Integrated Leak Rate Testing Intervals, Nuclear Energy Institute Project No. 689 (June 25, 2008) (ML081140105). 44 See 2002 IP2 Safety Evaluation at 2. 45 See id. 46 See id. 47 See LAR, attachment 2 (Technical Specification 5.5.14). 48 Id. 49 Id. The performance leakage rate is equal to the sum of the measured Type A test upper confidence limit (UCL) and the total as-left minimum pathway leakage rate (MNPLR) of all Type B or Type C pathways isolated during performance of the Type A test.

E. The IP2 Containment Leakage Rate Testing Program By letters dated August 7, 1996 and March 12, 1997, IP2 submitted a Technical Specification change request to implement Appendix J, Option B. The NRC approved that request as Amendment 190 issued on April 10, 1997. With the approval of the amendment, IP2 transitioned to a performance-based 10-year frequency for the Type A tests. On July 13, 2001 Entergy submitted an amendment request to extend the ILRT interval on a one-time basis from ten years to 15 years. The NRC approved that amendment request, as later supplemented, in Amendment 232 to the license issued on August 5, 2002. The current proposed extension of the primary containment ILRT from ten to 15 years, if approved, would mean that the next scheduled ILRT would need to be completed by March 2021 (instead of March 2016).51 Entergy previously conducted periodic ILRTs in 1979, 1984, 1987, 1991, and 2006. F. Required Code Inspections of the Reactor Containment 10 C.F.R. Part 50, Appendix J, Option B, paragraph III.A requires that, prior to each Type A test and at a periodic interval between tests based on the performance of the containment system, a general visual inspection of the accessible interior and exterior surfaces of the containment system be performed to identify structural deterioration that may affect the containment leak-tight integrity.52 In addition, inspections are performed as part of the Containment Inservice Inspection (ISI) Plan to implement the requirements of American Society performance criterion for a Type A test is met if the performance leakage rate is less than 1.0La. The acceptance criterion for the as-left Type A test is set at 75% of the allowed leakage rate (i.e., 0.75La), which provides a minimum 25% margin to address the possibility of containment leak tightness degradation over time between Type A tests while continuing to maintain less than the maximum allowable containment leakage rate (La). 50 See LAR, attachment 1, at 5-6 (Past IP2 ILRT results have confirmed that the containment is acceptable with respect to the design criterion of 0.1% leakage of containment air weight at the design basis loss of coolant accident pressure (La).). 51 Since the last ILRT was completed in April 2006, and the next one would be performed in March 2020 based on the current refueling outage schedule (if the LAR is granted), the actual interval would be about 14 years.

specifies the need for general visual examinations during at least three other outages before the next Type A test if the interval is extended to 15 years.60 IV. NEW YORKS PROPOSED CONTENTIONS ARE INADMISSIBLE A. Governing Legal Standards for Contention Admissibility Petitions to intervene must set forth with particularity the contentions a petitioner seeks to have litigated in a hearing.61 The requirements for an admissible contention are set forth in 10 C.F.R. § 2.309(f)(1)(i)-(vi) and also described in the Hearing Notice.62 The Commissions contention admissibility requirements are strict by design.63 They seek to ensure that NRC hearings serve the purpose for which they are intended: to adjudicate genuine, substantive safety and environmental issues placed in contention by qualified intervenors.64 As such, the requirements reflect a deliberate effort to prevent the major adjudicatory delays caused in the past by ill-defined or poorly-supported contentions that were admitted for hearing although based on little more than speculation.65 To warrant an adjudicatory hearing, proposed contentions thus must have some reasonably specific factual or legal basis.66 Under 10 C.F.R. § 2.309(f)(1), a petitioner must explain the basis for each proffered contention by stating alleged facts or expert opinions that support the petitioners position and on 60 See LAR, attachment 1, at 10. Tables 4.4-1 and 4.4-2 of the LAR illustrate the current and planned inspection intervals for the IP2 first and second IWE and IWL inspection intervals, respectively. See id. at 10-11. IP2 IWE containment inspections for the current fourth ISI interval were performed in 2008 (2R18), 2012 (2R20), and 2014 (2R21). See id. The results of those IWE inspections are summarized in Section 4.4.1 of the LAR. See id. at 11-12.

which the petitioner intends to rely in litigating the contention at hearing.67 To be admissible, the issue raised must fall within the scope of the proceeding and be material to the findings that the NRC must make with respect to the application.68 A contention, therefore, must provide sufficient information to show a genuine dispute with the applicant on a material issue of law or fact.69 The contention must refer to the portions of the application that the petitioner disputes along with the supporting reasons for each dispute; or, if the petitioner believes that an application fails altogether to contain information required by law, the petitioner must identify each failure and provide supporting reasons for the petitioners belief.70 B. Proposed Contention NYS-1 Is Inadmissible Because It Fails to the Meet the Requirements of 10 C.F.R. § 2.309(f)(1)(iii)-(vi) Proposed Contention NYS-1 claims that Entergys LAR does not demonstrate that it complies with 10 C.F.R. §§ 50.40 and 50.92 or 10 C.F.R. Part 50, Appendix J and, therefore, does not provide reasonable assurance of adequate protection for the public health and safety.71 New York presents six principal arguments or bases in support of its contention, which, for purposes of this response, Entergy refers to as Bases 1 through 6. They are: (1) Entergy has not adequately considered the plant-specific history of the IP2 containment liner;72 (2) Entergys request to postpone the containment integrity testing ignores recent inspections that revealed allegedly significant corrosion and other wear in the containment liner;73 (3) Entergy did not adequately consider new seismic data;74 (4) the LAR poses a significant hazard consideration under 10 67 10 C.F.R. § 2.309(f)(1)(ii), (v). 68 Id. § 2.309(f)(1)(iii)-(iv). 69 Id. § 2.309(f)(1)(vi). 70 Susquehanna, CLI-15-8, slip op. at 5 (quoting 10 C.F.R. § 2.309(f)(1)(vi)). 71 Petition at 5. 72 Id. at 6. 73 Id. at 8. 74 Id. at 10. 14
C.F.R. § 50.92(c);75 (5) the LAR relies on Entergys allegedly deficient license renewal SAMA analysis;76 and (6) Entergys alleged desire to reduce costs and maximize revenues also does not justify rolling back this important safety-related test.77 As demonstrated below, none of those bases supports the admission of Proposed Contention NYS-1.
- 1. Basis 1: Alleged Unique Degradation History of the IP2 Containment Liner New York asserts that conducting ILRTs at intervals exceeding 10 years is insufficient in view of certain historical unusual degradation events involving the IP2 containment liner.78 Specifically, it cites (1) buckling of the liner during initial plant construction in 1968, (2) deformation of the liner caused by a jet of steam and hot water in 1973, and (3) corrosion of the liner due to a flooding event in 1980.79 According to New York, these damaging incidents make IP2 ill-suited for the relaxed monitoring proposed by Entergy.80 New York further asserts that Entergys evaluation of the safety risk posed by the reduced ILRT inspection frequency fails to consider the cited history of events affecting the IP2 containment liner.81 For the reasons discussed below, none of these claims supports the admission of NYS-1.
As a preliminary matter, New York fails to explain how any of these historical eventsall of which occurred several decades agois germane to the instant LAR, which seeks to extend the ILRT interval by five years in accordance with current NRC regulations and NRC-approved industry guidelines. At a minimum, New York should have provided some assessment, preferably furnished by a qualified technical expert, explaining the significance of these events and how they 75 Id. at 8. 76 Id. at 19-20. 77 Id. at 10. 78 Id. at 2. 79 See id. at 2, 7-8, 13-15. 80 Id. at 6. 81 Id. at 7. 15
purportedly bear on the adequacy of the IP2 Containment Leakage Rate Testing Program. Indeed, such an assessment would have been particularly warranted here, given the specific, documented, and confirmed corrective actions taken in response to those events, and the various ILRTs, LLRTs, and visual/volumetric inspections performed to date (which have provided no indications that the IP2 containment is unable to perform its design function of maintaining integrity during accident conditions).82 Instead, New York relies solely on unsubstantiated claims by counsel, and ignores critical information contained in the very documents it references in its Petition.83 For example, New York asserts, without any supporting expert opinion or other credible factual basis, that performing ILRTs for the IP2 containment less frequently than every 10 years is insufficient to assure that there is a leak-tight barrier against the controlled release of radioactivity to the environment.84 However, New York overlooks that there are numerous containment tests and inspections (not just the ILRT) performed in accordance with other plant programs that collectively provide a high degree of assurance against containment degradation. As discussed in Section III, supra, 10 C.F.R. Part 50, Appendix J, identifies three types of required tests: Type A (ILRT), Type B, and Type C tests. Further, as stated in the LAR, Type B and C tests identify the vast majority of potential containment leakage paths.85 In fact, when the NRC revised Part 50 in 1995 to provide a performance-based option for containment leakage-rate testing, it specifically noted, based on findings contained in NUREG-1493, that Type B and C 82 See infra, pp. 16-29; see also LAR, attachment 1, at 5-13 (discussing results of IP2 tests and inspections). 83 As one Board aptly noted with respect to circumstances present here, if no expert opinion or supporting relevant documents are submitted, any fact-based argument that is provided must be reasonably specific, coherent, and logical, sufficient to show such a dispute and indicate the appropriateness of further inquiry.

tests are capable of detecting over 97 percent of containment leakages, and that of the 97 percent, virtually all leakages are identified by LLRTs of containment isolation valves (i.e., Type C tests).86 This was a key consideration in the NRCs decision to allow the ILRT performance-based option.87 In addition to leakage rate tests, Appendix J specifies that visual examinations of the accessible interior and exterior surfaces of containment structures and components be performed prior to any Type A test, and at periodic intervals between Type A tests to identify any evidence of structural deterioration that may affect either the containment structural integrity or leak tightness.88 Furthermore, the NRC Part 50 regulations mentioned above specify ISI, repair, and replacement requirements that licensees must meet with regard to reactor containment structures and associated pressure- retaining components.89 Accordingly, there is no basis for New Yorks suggestion that the ILRT is the only means by which a licensee can ensure the containments continuing structural integrity and ability to perform its intended safety function.90 Moreover, there is no basis for New Yorks apparent belief that an ILRT interval exceeding 10 years will lead to an unacceptable risk of an undetected loss of containment integrity or reduction in the margin of safety at IP2.91 Significantly, the very documents New York references in its Petition undermine its claims.92 Specifically, New York cites a number of historical documents as purported evidence 86 See Primary Reactor Containment Leakage Testing for Water-Cooled Power Reactors, 60 Fed.

for its claims regarding the alleged unique history of damaging events affecting the IP2 containment liner.93 As discussed below, those documents actually demonstrate that the 1968, 1973, and 1980 incidents cited by New York have not compromised the integrity of the IP2 containment liner. 1968 Liner Buckling: The first historical incident cited by New York occurred in 1968 during the initial construction of IP247 years ago. Specifically, during construction of the welded steel liner on the IP2 containment structure, a buckle or liner deformation was observed in the vicinity of the fuel transfer tube canal penetration.94 Plant construction specification 9321 225-3, Containment Building Liner, allowed a two-inch tolerance for local buckling.95 Field measurements taken in the buckled zone indicated two points at which the acceptable limits were exceeded by 1/8-inch and 5/16-inch, respectively.96 As stated in the January 1968 licensee-prepared report cited by New York, it was concluded that the integrity of the liner has not been violated.97 The report explains that because the liner material is highly ductile, and the liner is deflection-limited by the reinforced concrete-wall, strains in the liner will remain elastic and the leak proof integrity of the liner is maintained under all anticipated conditions.98 It further states that the engineers and constructors decided, in any case, to install a system consisting of a combination of a strongback and stud anchors to prevent additional buckling of these points under compressive loadings (by holding the liner to the 93 Petition at 7. 94 Report on the Containment Building Liner Plate Buckle in the Vicinity of the Fuel Transfer Canal, Indian Point Generating Station Unit No. 2 (Jan. 1968), at 1 (ML093521587). 95 See id. at 3. 96 See id. 97 Id. at 2. 98 Id. 18
concrete).99 Following repair of the liner bulge, leak tests were performed on the channels in the affected area, and magnetic particle inspection was made of all weld channel fillet welds in the same area.100 The weld channel system passed the leak and magnetic-particle tests, and the liner was determined to within the allowable tolerances at all points.101 Thus, nothing in the 1968 report cited by New York indicates that the IP2 liner fails to conform with the applicable specifications or is subject to unusual stresses.102 1973 Liner Deformation: The second incident cited by New York involved slight inward deformations of portions of the IP2 containment liner above the feedwater pipe penetrations that occurred as a result of the November 13, 1973 failure of a section of the feedwater line to Steam Generator No. 22. New York references four documents in connection with this event, each of which contradicts New Yorks claims of a structurally-compromised containment liner. The first document is a November 30, 1973 letter from Consolidated Edison (Con Edison), the previous IP2 licensee, to the Atomic Energy Commission (AEC), providing supplemental information concerning the incident.103 Among other things, that letter states that: There is no visual 99 See id. at 8. 100 See id. at 2. 101 See id. 102 Petition at 13, 14. Furthermore, the Commission necessarily inspected and approved the final, as-built design of the IP2 containment structure, including the steel liner, before authorizing fuel load and plant operation. See Safety Evaluation by the Division of Reactor Licensing, U.S. Atomic Energy Commission, In the Matter of Consolidated Edison Company of New York, Incorporated, Indian Point Nuclear Generating Unit No. 2, Buchanan, New York, Docket No. 50-247 (Nov. 16, 1970) (ML072260449); Supplement No. 1 to AEC Regulatory Staff Safety Evaluation, In the Matter of Consolidated Edison Company, Indian Point Nuclear Generating Plant Unit 2, Docket No. 50-247 (Nov. 20, 1970) (ML072260452); Supplement No. 2 to AEC Regulatory Staff Safety Evaluation, In the Matter of Consolidated Edison Company, Indian Point Nuclear Generating Plant Unit 2, Docket No. 50-247 (July 1971) (ML072260453). Notably, the Commissions November 1970 safety evaluation report (SER) (page 81) references the January 1968 report discussed above, and Supplement 1 to the SER (Appendix A, page 1) indicates that the NRC reviewed corrective actions related to the containment liner bulge during a site inspection. Supplement 1 (page 15) specifically states that [b]ased on our inspections to date, we conclude that there is reasonable assurance that the containment and other Class I structures will be completed in accordance with AEC regulatory requirements. 103 See Letter from William J. Cahill, Jr., Consolidated Edison, to James P. OReilly, AEC (Nov. 30, 1973) (ML093560700). 19
evidence of any reduction in containment liner integrity. In addition, the weld channel penetration and pressurization system air consumption in this area of containment following the incident was normal.104 The second document cited by New York is Con Edisons Feedwater Line Incident Report - Indian Point Unit No. 2, dated January 14, 1974.105 The report notes that in response to the event, Con Edison performed a survey of the liner profile, ultrasonic testing of liner studs, magnetic particle inspection of the liner, bend tests, and pressure and leak tests.106 Importantly, the report states that throughout and subsequent to the incident, there was no evidence of any reduction in containment liner integrity, and that the weld channel penetration and pressurization system air consumption in the affected area of containment following the incident was normal.107 It further states that the results of a Type B leakage test performed following the replacement of the pipe and endplates in the Line No. 22 feedwater penetration indicated that the leakage was small and acceptable for continued service and safe operation of the facility.108 Appendix IV of the report contains a detailed analysis of the containment liner, and concludes that the integrity of the deformed liner area had not been violated by the incident.109 104 Id. at 5. 105 See Consolidated Edison Company of New York, Inc., Feedwater Line Incident Report - Indian Point Unit No. 2 (Jan. 14, 1974) (ML100200180). 106 See id. at 4-8 to 4-24. 107 Id. at 3-2. 108 Id. at 4-24. Section 6 of the report discusses the various modifications and repairs to the liner. An additional 18 feet of insulation was added above the pipe break area completely around the inside of containment to preclude local heating and the resultant bulging similar to that which occurred with the incident. In the vicinity of feedwater and steam lines, the insulation was extended an additional eight feet. The failed section of feedwater piping was removed and replaced with a new section extending from the first elbow outside containment through the penetration, to near the first elbow inside containment. The containment penetration end plates and expansion joints were replaced. See id. at 6-3 to 6-4. 109 See id., app. IV at IV-29. 20
The third document referenced in the Petition is a March 12, 1974 follow-up letter from Con Edison to the AEC.110 The concluding paragraph of the letter states that, based on the results of the special liner leakage test and other tests and analyses performed on the containment liner,111 Con Edison concludes that the effects of the feedwater incident which occurred on November 13, 1973 did not impair the ability of the containment liner to perform its function and that the original acceptance criteria for containment leakage are still satisfied.112 Finally, the fourth document cited by New York is an April 15, 1974 internal AEC letter documenting the agencys regulatory evaluation of the structural portions of the January 14, 1974 Feedwater Line Incident Report.113 As reflected in this document, the AEC agreed with Con Edisons conclusion that the damage to the liner has not impaired its integrity and that it can perform its function with an adequate margin of safety.114 New York does not challenge any of the conclusions contained in the aforementioned documents. As it correctly notes, in the April 15, 1974 letter, the AEC stated that increased attention should be given to the surveillance of the liner during the life of the plant, and that the 110 See Letter from Letter from William J. Cahill, Jr., Consolidated Edison, to James P. OReilly, Atomic Energy Commission (March 12, 1974) (ML093560204). 111 As discussed in the March 12, 1974 letter, Con Edison initially had performed two special leak rate tests, during which containment pressure was increased gradually to 47 psig and stabilized at that pressure, in order to verify the containment liner integrity following the slight bulging that resulted from the feedwater incident. See id. at 1
& attachment 1. The leakage was determined to be approximately 0.029% per day of the containment free volume, which is well within both the design leakage limit of 0.1% per day and the more restrictive criterion for the test of 0.04% per day. See id. at 1. Con Edison also performed a third special leakage test with the Containment Weld Channel and Penetration Pressurization System (WC&PPS) (described in Section III.A above). The results of that test, when analyzed in conjunction with the results of the first two tests, yielded a still-acceptable leak rate of 0.034% per day. See id. at 1 & attachment 2.

frequency of the leakage tests required by the Technical Specification should be increased.115 That fact, however, does not undermine the robust technical justification for the requested ILRT interval extension contained in the LAR, including the plant-specific PRA-based risk impact assessment. The AECs recommendation regarding increased testing frequency was made over 40 years ago based on the information and technical knowledge then available to it. Unsurprisingly, since that time, the NRCs and industrys understanding of containment-related phenomena and integrated leakage rate testing has increased substantially as a result of subsequent technical studies and four decades of operating experience. Indeed, it is that enhanced understanding and additional operating experience that led the NRC to issue in 1995 a new risk-based regulation based on the performance history of components (containment, penetrations, valves) as the means to justify an increase in the interval for Type A, B, and C tests,116 and to approve one-time and permanent extensions of the ILRT interval from 10 to 15 years for various plantsincluding IP2 and IP3.117 1980 Flood-Related Corrosion: The third historical incident mentioned by New York occurred on October 17, 1980. As noted in NRC IE Information Notice No. 80-37, personnel entering the IP2 containment to make a component repair discovered that water from leaking service water pipes had accumulated on the containment floor.118 Citing the NRC Staffs safety evaluation for the 2002 license amendment that allowed a one-time extension of the IP2 ILRT interval from 10 to 15 years, New York states that this event resulted in the corrosion of the containment liner at the 46 ft. elevation, where it meets the concrete containment floor.119 115 See id., encl. at 4. 116 Primary Reactor Containment Leakage Testing for Water-Cooled Power Reactors, 60 Fed.

New York again ignores those portions of the document that undercut its argument. The NRC Staffs safety evaluation for the 2002 ILRT-related license amendment specifically discusses the 1980 containment flooding event.120 It notes that during the 2000 refueling outage, Entergy examined the IP2 containment liner plate in accordance with ASME Code requirements as part of an ISI program inspection.121 Specifically, Entergy performed ultrasonic testing (UT) of the liner plates near the 46 ft. elevation (containment concrete floor) to determine the extent of corrosion.122 The areas examined included all locations at which there was degradation of the moisture barrier or the concrete floor.123 The measured liner thicknesses were greater than the conservatively specified minimum liner thickness (0.34 in.) required to maintain containment pressure boundary integrity.124 Entergy also repaired the moisture barrier seal (between the concrete containment floor and the insulation mounted on the containment wall in areas where it had deteriorated) to prevent any further corrosion of the liner below the cylinder/containment floor interface.125 Based on its review of the examination results, the Staff found reasonable assurance that the examinations had identified the minimum liner thickness in the areas where the liner is most likely to have been affected by the 1980 flooding event.126 It further concluded that the structural integrity of the containment is acceptable because the remaining liner thickness is sufficient to withstand the loading associated with design-basis accident conditions.127 Also noting Entergys 120 See 2002 IP2 Safety Evaluation at 8-10, 14 (ML021860178). 121 See id. at 8. 122 See id. 123 See id. 124 See id. 125 See id. at 9. 126 See id. at 8. 127 Id. 23
planned future re-inspections of the affected areas, the Staff found the licensees approach for ensuring that the integrity of the containment liner will be maintained to be acceptable.128 In summary, insofar as it relies on Basis 1, NYS-1 fails to satisfy the criteria of 10 C.F.R. § 2.309(f)(1)(iv), (v) and (vi). New York fails to: (1) establish that the various historical events discussed in its Petition are material to the Staffs findings on the instant LAR; (2) provide any support for its claim that the structural integrity and intended function of the IP2 containment liner have been compromised; and (3) explain why the LAR is deficient when evaluated under the NRCs current ILRT requirements and related NRC-approved guidelines.
- 2. Basis 2: Alleged Insights from Previous Tests and Inspections Despite the contrary evidence discussed above, New York asserts that more recent inspections of the IP2 containment surfaces, including the containment liner, confirm that the liner and related surfaces have been harmed by the historical accidents.129 For example, citing the 2002 NRC safety evaluation report discussed above, New York states that visual and UT inspections of the liner plate conducted during the 2000 refueling outage revealed coating deterioration and corrosion.130 It further states that during IWE inspections performed in 2008, 2012, and 2014, inspectors observed general surface corrosion, minor coating peeling/flaking, blistered paint, as well as loose or buckling stainless steel insulation panels.131 New York posits that because the last ILRT was performed in 2006, it is unknown whether the indications observed in these visual inspections would result in the failure of an ILRT.132 128 Id. at 9.
129 Petition at 17. 130 See id. at 17-18. 131 See id. at 18. 132 Id. at 18-19. 24
As an initial matter, it bears emphasis that the limited surface corrosion and conditions cited by New York were identified during IWE visual inspections, the frequency of which is unaffected by the LAR. In addition, New York fails to explain why or how any of the observed conditions could result in the failure of an ILRT.133 Finally, New Yorks arguments again are belied by the supporting evidence on which it purports to rely. As discussed above, the NRC Staffs 2002 safety evaluation report concluded that the structural integrity of the containment liner is acceptable despite some observed liner corrosion.134 The later (i.e., 2008, 2012, and 2014) IWE inspections are specifically discussed in Entergys LAR, which contains the following uncontroverted findings and conclusions: Refueling Outage 2R18 (2008) Containment Inservice Inspection: The general surface corrosion, minor coating peeling/flaking, and blistered paint were previously identified and evaluated. These conditions were a repeat of previous inspections and were minor with no change and therefore acceptable. The condition of the buckling locations and looseness on the VC liner plate insulation (columns 10 and 11 elevation 68 feet) was documented in the Corrective Action Program as Condition Report CR-IP2-2008-01892. Civil Engineering performed an inspection of the stainless steel insulation jacket and has determined that all but two of the insulation jacket issues are acceptable. The two areas not acceptable were repaired during 2R18 outage.135 Refueling Outage 2R20 (2012) Containment Inservice Inspection: All of the conditions noted during this inspection did not result in any structural degradation that adversely affects the ability of the containment to perform its design function of maintaining integrity during accident conditions.136 Refueling Outage 2R21 (2014) Containment Inservice Inspection: Most of the findings were a repeat of previous inspections and were minor with no change and therefore acceptable. All non-destructive examination (NDE) reports were accepted during the 2014 containment inspection therefore no condition reports were generated.137 133 Id. at 19. 134 See 2002 IP2 Safety Evaluation at 8-9 (ML021860178). 135 See LAR, attachment 1, at 11-12. 136 See id. at 12. 137 See id. The LAR (Section 4.4.2) also discusses the results of IWL general visual inspections performed in 2005 and 2010. It states that all of the recordable indications identified during the inspections have been evaluated, and that none of them is a structural concern or reduces the structural capacity or ability of the containment structure to perform its safety function. See id. at 12-13. 25
New York also cites the results for the five ILRTs discussed in the LAR, as performed between August 1979 and April 2006.138 Quoting an NRC Staff RAI issued to Entergy on April 28, 2015, New York states that As found Leakage measured during the five ILRTs is on a continuous trend towards eclipsing the IP2 Technical Specification 5.5.14.d.1 leakage rate acceptance criteria of 0.75La (i.e., 0.075 percent containment air weight per day).139 Based on simple extrapolation of the data, New York states that the expected leakage rate for an ILRT conducted in 2016 would be 0.078, exceeding the current Technical Specifications leakage rate acceptance criteria of = 0.75La.140 That argument also lacks adequate support and fails to raise a genuine dispute on a material issue of fact or law.141 New York must do more than rest on the mere existence of RAIs as a basis for [its] contention,142 because the issuance of an RAI does not alone establish deficiencies in the application, or that the NRC Staff will go on to find any of the Applicants clarifications, justifications, or other responses to be unsatisfactory.143 Indeed, in CLI-15-8, the Commission recently reiterated that RAIs are a routine means for the Staff to ask for clarification or additional corroborating information from an applicant.144 They reflect follow-up 138 See Petition at 16-17. 139 See id. at 17; Letter from Douglas V.

questions, an ongoing dialogue between the Staff and applicant.145 As such, [r]arely will pointing to an RAI, without more, suffice as support for an admissible contention.146 In any case, a contention alleging an error or omission in an application must establish some significant link between the claimed deficiency and protection of the health and safety of the public or the environment.147 In other words, the petitioner must make at least a minimal demonstration that the application under review fails to meet a statutory or regulatory requirement.148 New York has not done so here through its reference to the Staffs RAI and simple extrapolation of the five available ILRT data points. Specifically, as reflected in the LAR and further explained in Entergys June 8, 2015 response to the NRC Staffs RAI, all five of the ILRTs conducted at IP2 between August 1979 and April 2006 have satisfied the as-found leakage acceptance criterion of 1.0La, as specified in IP2 Technical Specification 5.5.14.149 This demonstrates that the overall containment leakage (Type A, Type B and Type C) has been maintained at leakage rates less than the assumed leakage rate in the plant accident analysis.150 Thus, Entergy does not believe that the IP2 Type A ILRT test 145 Id.

results since August 1979 indicate that the IP2 containment is degrading or constitutes an adverse trend requiring corrective action.151 Furthermore, even if the next as-found leakage is determined to be 0.78La, which New York predicts for an ILRT performed in 2016 based on its extrapolation of the current data, that value still will be less than the applicable as found acceptance criterion of 1.0La. In fact, even if the data are extrapolated to 2021 using New Yorks approach, the resulting as-found leakage rate value would be 0.85La, which still is less than the acceptance criterion of 1.0La.152 Importantly, if the measured as-found leakage exceeded 1.0La, then Unit 2 could not resume operations, and Entergy would need to take appropriate corrective actions, including more frequent testing.153 In addition, the IP2 Containment Leakage Rate Testing Program requires that the as left criterion of 0.75La be met prior to plant restart, to ensure that there is sufficient margin to accommodate potential degradation that could increase the containment leakage rate before the next ILRT is performed.154 Thus, in view of the above, New York has not shown that 151 See id. 152 See id. 153 See id. at 5-6. As noted in Entergys June 8, 2015 RAI Response (attachment at 5-6), NEI 94-01, Rev. 2-A specifically states: The performance criterion for Type A tests is a performance leakage rate (as defined in this guideline) of less than 1.0La. Type A testing shall be performed at a frequency of at least once per 15 years. If the Type A performance leakage rate is not acceptable, the performance criterion is not met, and a determination should be performed to identify the cause of unacceptable performance and determine appropriate corrective actions. Once completed, acceptable performance should be reestablished by demonstrating an acceptable performance leakage rate during a subsequent Type A test before resuming operation and by performing another successful Type A test within 48 months following the unsuccessful Type A test. Following these successful Type A tests, the surveillance frequency may be returned to at least once per 15 years.

the LAR fails to meet a statutory or regulatory requirement or identified any substantive safety issue.155
- 3. Basis 3: Alleged Effect of the Elevated Seismic Hazard Referring to ongoing analyses done in connection with the NRCs various post-Fukushima initiatives, New York accuses Entergy of ignoring recent updates indicating elevated seismic hazards at the Indian Point site and not adequately considering the risk that the degraded containment liner and related containment systems and components will fail as a result of seismic activity at IP2.156 Specifically, New York states that new, revised seismic curves show that the anticipated ground motion is larger for higher frequency events than was understood when IP2 received its operating license in 1973,157 and this has led the NRC Staff to designate IP2 as Priority Group 1 plant for purposes of the NRCs and industrys ongoing Fukushima-related seismic hazard re-evaluations.158 Basis 3 is not adequately supported and fails to explain why the LAR suffers from any defect, much less a material defect warranting further exploration by the Board.159 To begin with, New York ignores the NRCs unequivocal statement, in the May 21, 2014 NRC internal memorandum cited by New York, that the NRC considered the re-evaluated hazard and previous estimates of plant capacity to conclude that this plant is safe to continue operating while 155 Indian Point, 68 NRC at 187 (stating that the NRCs contention admissibility rules require a petitioner to make at least a minimal demonstration that the application fails to meet a statutory or regulatory requirement).
156 Petition at 1, 10. 157 Id. at 15. 158 Id. at 16. NRC power reactor licensees have performed seismic hazard re-evaluations in response to an NRC request for information issued on March 12, 2012, pursuant to 10 C.F.R. § 50.54(f). 159 See Crow Butte Res., Inc. (North Trend Expansion Project), CLI-09-12, 69 NRC 535, 553 (2009) (noting that when a petitioner neglects to provide the requisite support for its contentions, a licensing board may not make assumptions of fact that favor the petitioner or supply information that is lacking). 29
additional evaluations are conducted.160 Consequently, there has been no change to the IP2 seismic design basis as a result of the ongoing seismic re-evaluation. Thus, there is no basis for New Yorks apparent belief that the IP2 containment structure and liner are somehow now more susceptible to seismically-induced failure that could lead to an unacceptable radiological release. Additionally, if a petitioner believes that an application does not adequately address a relevant issue, then the petitioner must explain why the application is deficient.161 New York has not done so here. Citing pages of 5-26 to 5-31 of the confirmatory risk analysis submitted by Entergy in support of the LAR, New York merely avers that [t]he LAR does not address these new seismic data.162 It makes no attempt to explain why the new seismic data are relevant to the ILRT LAR or associated risk analysis; how, if at all, they might be considered within the context of those documents; and what impact, if any, they might have on the risk analysis results.163 Given that the IP2 seismic design basis has not changed as a result of the new, revised seismic curve, there is no basis for including the new seismic data in the LAR risk impact evaluation. Here, counsel for New York merely speculates, with no technical or expert opinion 160 Memorandum from Scott C. Flanders, NRC, to David Skeen, NRC,

(inset to preliminary ground motion response spectra (GMRS) comparison plot for Indian Point Unit 2) (emphasis added) (ML14136A126). In making this statement, the NRC Staff referenced its May 9, 2014 letter to Entergy and other reactor licensees informing them of the NRCs seismic screening and prioritization determinations and expectations regarding further seismic risk evaluations. See Letter from Eric Leeds, NRC, to All Power Reactor Licensees and Holders of Construction Permits (May 9, 2014) (ML14111A147). The May 9, 2014 letter explains that based on its review of a March 12, 2014 EPRI fleet-wide seismic risk and design margin study and each licensees March 2014 plant-specific interim evaluation, the Staff confirmed that the conclusions reached in [Generic Issue]-199 safety/risk assessment remain valid and that the plants can continue to operate while additional evaluations are conducted.

Reg. at 33,170. 162 Petition at 10. 163 In this regard, New York does not directly take issue with any statement in the risk impact assessment prepared by Entergy vendor ERIN Engineering. For example, the risk impact assessment report states that the seismic risk contribution of 1.06E-05/yr used in the risk impact assessment was obtained from the seismic portion of the IP2 IPEEE, which was a conservative analysis.

support, that there is a greater risk that the containment liner will fail as a result of seismic activity at IP2.164 In view of the above, NYS-1 fails to meet the contention admissibility requirements in 10 C.F.R. § 2.309(f)(1)(iii)-(vi) insofar as it relies in Basis 3 for support.
- 4. Basis 4: Alleged Existence of Significant Hazards Consideration New York further asserts that, contrary to Entergys and the NRC Staffs conclusions, the LAR poses a significant hazard consideration under 10 C.F.R. § 50.92(c).165 New York makes two arguments in support of that assertion. First, it claims that the requested ILRT interval extension increases the consequences of a release of radiation from the reactor, since any such release might escape containment and reach the environment and citizens of the State in amounts that exceed NRC safety standards.166 Second, New York claims that the LAR involves a significant reduction in a margin of safety under 10 C.F.R. § 50.92(c)(3) because reducing the frequency of ILRTs necessarily reduc[es] the margin of safety for containment integrity.167 Basis 4 fails to support the admission of NYS-1 for multiple reasons. As a threshold legal matter, 10 C.F.R. § 50.58(b)(6) explicitly bars the type of challenge raised by New York here. It states: No petition or other request for review of or hearing on the Staffs significant hazards consideration determination will be entertained by the Commission.168 As stated in the Hearing Notice, the NRC reviewed Entergys significant hazards consideration analysis in the LAR, and concluded that the standards of 10 C.F.R. § 50.92(c) are satisfied. Therefore, it propose[d] to 164 Petition at 10.

determine that the amendment request involves no significant hazards consideration.169 As another licensing board noted recently noted, [a] no significant hazards consideration determination is a procedural decision barred from litigation pursuant to 10 C.F.R. § 50.58(b)(6) and licensing board precedent.170 Accordingly, Petitioners argument is outside of the Boards jurisdiction, and is not subject to challenge in this proceeding.171 Even assuming New Yorks challenge to the Staffs proposed no significant hazards consideration determination was procedurally permissible (which it is not), the challenge is devoid of factual or technical support. In short, New York relies solely on speculation by counsel and claims that Entergy already has shown above to be groundless, viz., the alleged unique degradation history of the IP2 containment liner (including wear and degradation observed during more recent tests and inspections);172 the IP2 containments trending towards failing an ILRT by 2016;173 and the purportedly elevated seismic hazards at the Indian Point site.174 Further, New York fails to controvert any aspect of Entergys no significant hazards consideration analysis (as contained in the LAR and described in the Hearing Notice), which contains a number of key technical points that undermine various claims made by New York in its Petition: 169 Hearing Notice, 80 Fed.

The proposed amendment does not involve a physical change to the plant (i.e., no new or different type of equipment will be installed) or a change to the manner in which the plant is operated or controlled. Nor does it alter the manner in which safety limits, limiting safety system setpoints, or limiting conditions for operation are determined.175 The containment itself and the testing requirements to periodically demonstrate the integrity of the containment exist to ensure the plants ability to mitigate the consequences of an accident and do not involve any accident precursors or initiators.176 The proposed amendment adopts the NRC-accepted guidelines of NEI 94-01, Revision 2A, for development of the IP2 performance-based testing program for the Type A testing. The specific requirements and conditions of the Containment Leakage Rate Testing Program, as defined in the Technical Specifications, ensure that the degree of primary containment structural integrity and leak-tightness that is considered in the plants safety analysis is maintained.177 Entergys confirmatory risk assessment using the IP2 PRA model concludes that extending the ILRT test interval from ten years to 15 years results in a very small change to the risk profile. Further, Entergy has determined that the increase in conditional containment failure probability due to the proposed change would be very small.178
- 5. Basis 5: Alleged Reliance on Erroneous Information from the IP2 License Renewal SAMA Analysis New York claims that the LAR is deficient because it purportedly relies on certain information obtained from the SAMA analysis prepared as part of the IP2 license renewal application.179 New York assertsagain without reference to any supporting technical analysis or expert opinionthat the SAMA analysis omits important considerations and contains erroneous assumptions and inputs that work to undercount the costs of an offsite radiation release and therefore skew the cost benefit analysis in favor of the requested amendment.180 In particular, it claims that the SAMA analysis: (1) does not take into account the value or decontamination cost of offsite properties with iconic value, natural resources, or critical infrastructure; (2) artificially 175 See LAR, attachment 1, at 17-18.
176 See id. at 17. 177 See id. at 17-18. 178 See id. at 17-18. 179 See Petition at 19-20. 180 Id. at 19. 33
and improperly limits its scope to land and population only within 50 miles of the site; and (3) relies on an outdated dollar per person-rem value of $2,000.181 Basis 5 does not support NYS-1 because it fails to provide an adequately supported and reasoned statement of why the LAR is unacceptable in some material respect.182 First, New York provides nothingno credible facts, supporting references, or expert opinionto support its statements regarding the license renewal SAMA analysis. Second, it fails to establish any nexus between its (unsubstantiated) criticisms of the license renewal SAMA analysis and the contents of the LAR, particularly the risk impact assessment. Entergy can discern no such nexus given the vagueness of New Yorks claims and its failure to explain with particularity how those claims relate to the assumptions and methods actually used in the risk impact assessment. Insofar as the risk impact assessment discusses the IP2 license renewal SAMA analysis, it makes the following points: External events were accounted for in the risk impacts analysis based on the available information from the IP2 IPEEE, as reported and used in the license renewal SAMA analysis; i.e., the external events CDF contribution values used in the risk impact assessment for the relevant external event initiator groups (seismic, internal fire, high winds) are consistent with those used in the SAMA analysis.183 Since the most current external events models for IP2 and IP3 are those embodied in the IPEEE, a multiplier was applied to the internal events results based on the IPEEE, similar to that used in the SAMA analysis.184 Dose results for the containment failures modeled in the PRA can be characterized by information that was prepared to support the license renewal SAMA analysis. This information was supplemented with revised calculations for the base case containment intact scenarios, which are critical for use in the ILRT extension assessment.185 181 Id. at 20. 182 See Fla. Power & Light Co. (Turkey Point Nuclear Generating Plant, Units 3 & 4), LBP-90-16, 31 NRC 509, 521, 521 n.12 (1990). 183 See LAR, attachment 3, at 5-26 to 5-29. 184 See id. at 5-26. 185 See id. at 3-1. More specifically, in the risk impact assessment, plant-specific release analyses were performed to estimate the weighted average person-rem doses to the population within a 50-mile radius from Unit 2. The releases were based on a combination of the information obtained from the IP2 SAMA analysis, additional 34
The use of the projected 2035 population to estimate population dose within a 50-mile radius of the plant for various release categories is consistent with the approach used in the license renewal SAMA analysis.186 It is entirely unclear how New Yorks vague claims regarding the economic value of iconic properties, distance truncation, and the $2,000 per person-rem value relate to, much less directly challenge, the assumptions and methodologies described in the risk impact assessment.
- 6. Basis 6: Entergys Alleged Desire to Reduce Costs and Maximize Revenues to the Detriment of Plant Safety New York asserts that Entergys desire to reduce costs and maximize revenues does not justify rolling back this important safety-related test.187 It bases this claim on Entergys statement in the LAR that [t]he performance of fewer ILRTs would result in significant savings in radiation exposure to personnel, cost, and critical path time during future refueling outages.188 New York further states that reduced costs and outage times are not relevant to the NRCs review of the LAR or adequate protection findings, and do not justify exposing millions of State citizens and the State environment to exposure from radiation escaping from a damaged containment structure.189 population dose runs for the intact containment scenarios, and the Level 2 PRA containment failure release frequencies. See id. at 5-6.
186 See id. at 3-1. In a related vein, New York criticizes Entergys reliance (in the risk impact assessment) on NUREG-1493, noting that the representative pressurized water reactor (PWR) considered in that study was the Surry reactor, located in rural Virginia. According to New York, it is wholly inappropriate to use Surry as a benchmark plant and site for regulatory analysis in a license amendment for IP2, which is located in a densely populated urban and suburban environment and has been subjected to various unique degradation events. Petition at 19. This argument is factually groundless, and fails to recognize the manner in which the IP2 ILRT risk impact assessment was performed. Specifically, that assessment makes use of plant-specific Level 1 and Level 2 PRA information (e.g., initiating events, accident sequences, source terms and release frequencies) as well as Indian Point region-specific population data. The fact that NUREG-1493 used Surry as a representative PWR plant is wholly irrelevant to Entergys LAR and the detailed plant-specific technical justification set forth therein. 187 Petition at 10. 188 Id. (quoting LAR, attachment 1, at 3). 189 Id. at 10-11. 35
New Yorks assertions are both factually groundless and irrelevant. Nowhere in the LAR does Entergy cite reduced costs or outage times as justification for the requested 5-year extension of the ILRT interval. It simply notes that reduced radiation exposure to personnel, costs, and outage lengths are expected to result from an increased ILRT interval. Notably, when Entergy sought an identical ILRT interval extension for IP3 last year, New York made similar statements in comments on the associated license amendment request. As documented in its March 13, 2015 safety evaluation, the NRC Staff rejected New Yorks claim that Entergys references to reduced costs were legally impermissible.190 The Staff explained that when the Commission issued the rules allowing licensees to request performance-based containment leak rate testing, it noted its expectation that licensees likely would save money by using the performance-based option.191 Therefore, the Staff further noted, Entergys statement that it expected to save money is congruent with the Commissions expectations.192 The Staff then emphasized that although cost-saving may result from the Commissions rules, cost is not a factor to be considered under 10 C.F.R. § 50.57(a), 10 C.F.R. § 50.54(o), or Appendix J to 10 C.F.R. Part 50, or in considering any related license amendment request.193 The Staff noted that New Yorks concerns should be assuaged in light of these facts.194 In summary, insofar as NYS-1 relies on Basis 6, it lacks adequate support, fails to raise a genuine dispute on a material issue of fact or law, and fails to directly challenge some material aspect of the application. Therefore, it is inadmissible under 10 C.F.R. § 2.309(f)(1)(iv)-(vi). 190 See Letter from Douglas V. Pickett, NRC, to Vice President, Operations, Entergy Nuclear Operations, Inc., Indian Point Energy Center, Indian Point Nuclear Generating Unit No. 3 - Issuance of Amendment Re: Extension of the Type A Containment Integrated Leakage Rate Test Frequency from 10 to 15 Years (TAC No. MF3426) (Mar. 30, 2015), encl. 2 (Safety Evaluation) at 15-16 (ML15028A308). 191 See id. at 16. 192 Id. 193 Id. 194 Id. 36
C. Proposed Contention NYS-2 Is Inadmissible Because It Fails to the Meet the Requirements of 10 C.F.R. § 2.309(f)(1)(iii)-(vi) In NYS-2, New York asserts that Entergy and the NRC Staff must perform an environmental review of the LAR under NEPA.195 In short, New York argues that, contrary to Entergys and the Staffs conclusions, the LAR poses a significant hazard consideration under 10 C.F.R. § 50.92(c).196 It further asserts that because the LAR (purportedly) involves a significant hazards consideration, it does not qualify for the categorical exemptions from environmental review under 10 C.F.R. § 51.22(c)(9), and that under 10 C.F.R. § 51.101(a)(1), the Commission cannot act on the LAR until an environmental review is complete.197 NYS-2 must be rejected as inadmissible because it constitutes a second impermissible challenge to the NRC Staffs proposed no significant hazards determination. Indeed, New York incorporates by reference the same arguments presented in support of Basis 4 of NYS-1. Accordingly, NYS-2 should be rejected for the same reasons discussed above (see supra, pages 31-33). In short, 10 C.F.R. § 50.58(b)(6) and related precedent bar adjudicatory challenges to the Staffs no significant hazards consideration determination. Inasmuch as New York challenges that determination and contends that an environmental review of the LAR is required by NEPA, it also improperly challenges 10 C.F.R. § 50.58(b)(6) and 10 C.F.R. § 51.22(c)(9) (which categorically excludes amendments or exemptions involving no significant hazards consideration from an environmental review under NEPA and 10 C.F.R. Part 51). A contention that challenges an NRC rule is outside the scope of the proceeding because, absent a waiver, no rule or regulation of the Commission . . . is subject to attack . . . in any adjudicatory proceeding.198 Finally, as discussed 195 Petition at 20. 196 Id. at 21. 197 Id. at 21-22. 198 10 C.F.R. § 2.335(a). A party can petition for a waiver of a specific NRC regulation, based on a showing of special circumstances such that application of the rule would not serve the purposes for which it was adopted. 37
above, New Yorks objections to the Staffs proposed no significant hazards consideration determination lack factual and technical support. Moreover, they are inconsistent with numerous other no significant hazard consideration determinations made by the Staff in its previous approvals of permanent and one-time extensions of plant ILRT intervals from 10 to 15 years.199 Accordingly, NYS-2 raises an issue that is outside the scope of this proceeding, contrary to 10 C.F.R. § 2.309(f)(1)(iii). The contention also fails to raise a material issue, lacks legal or factual support, and fails to demonstrate that a genuine dispute exists on a material issue of law or fact. As such, it also is inadmissible under 10 C.F.R. § 2.309(f)(1)(iv), (v), and (vi). V. CONCLUSION As demonstrated above, New York has not proffered a contention that satisfies the contention admissibility requirements in 10 C.F.R. § 2.309(f)(1). Therefore, the Board should reject New Yorks Petition in its entirety. Id. § 2.335(b); see also Dominion Nuclear Conn., Inc. (Millstone Nuclear Power Station, Units 2 & 3), CLI 24, 62 NRC 551, 559-60 (2005) (laying out a four-factor test for determining whether to grant a waiver). However, as New York has not petitioned for a waiver of any NRC regulation, this process need not be discussed further. 199 See, e.g., NRC safety evaluations contained in the documents referenced in footnote 12 above. 38
