Pursuant to 10 C.F.R. § 2.1209, and the Atomic Safety and Licensing Boards (Board)

February 28, 2013 Order,1 Entergy Nuclear Operations, Inc. (Entergy) submits its Proposed Findings of Fact and Conclusions of Law (Proposed Findings and Conclusions) on New York State (New York) Consolidated Contention NYS-12C (NYS-12C).

The Proposed Findings and Conclusions are based on the evidentiary record in this proceeding, and are submitted in the form of a proposed Partial Initial Decision by the Board.

The Proposed Findings and Conclusions are set out in numbered paragraphs, with corresponding citations to the record of this proceeding.

I. INTRODUCTION

1. This Partial Initial Decision presents the Boards Findings of Fact and Conclusions of Law on NYS-12C, which relates to Entergys and the U.S. Nuclear Regulatory Commissions (NRC or Commission) Staffs compliance with the National Environmental Policy Act (NEPA),2 as implemented by the NRCs 10 C.F.R. Part 51 regulations. NYS-12C 1

challenges the adequacy of Entergys severe accident mitigation alternative (SAMA) analysis for Indian Point Energy Center (IPEC), as reviewed and approved by NRC Staff in the December 2010 Final Supplemental Environmental Impact Statement (FSEIS) for IPEC license renewal.3 Specifically, NYS-12C alleges that Entergy and the NRC Staff have significantly underestimated the economic costs of a severe accident at IPEC by relying on computer code input values that are not specific to the uniquely urban area surrounding IPEC, and that do not sufficiently take into account the greater difficulty and costs of cleaning up small-sized radioactive particles released by a severe reactor accident.4 As pursued at hearing, NYS-12C particularly focuses on the decontamination cost and decontamination time values (among other economic parameters) used by Entergy as inputs to the MELCOR Accident Consequence Code System Version 2 (MACCS2), the computer code which Entergy used to perform the offsite consequences portion of its SAMA analysis.5

2. Having considered all of the record evidence, the Board concludes that the contested SAMA analysis computer code inputs are reasonable and appropriate, as judged under NEPAs rule of reason6 and given the NRCs and industrys current state of knowledge and practice regarding SAMA analyses and other severe accident consequence assessments.

Moreover, the Board concludes that New Yorks criticisms of Entergys MACCS2 inputs (including New Yorks proposed alternative input values) do not credibly render the SAMA 3

analysis altogether unreasonable under NEPA standards.7 Nor, in the Boards view, do they support a finding that there are additional potentially cost-beneficial SAMA candidates beyond those identified in the Staffs FSEIS.8

3. Accordingly, the Board finds that the NRC Staff and Entergy have carried their respective burdens of proof on this contention, and resolves NYS-12C in their favor. The Board further finds that the NRC Staffs reliance upon Entergys SAMA analysis in satisfaction of its obligations under NEPA and 10 C.F.R. Part 51 is reasonable. In accordance with well-established NRC adjudicatory practice, the FSEIS is deemed supplemented by this decision.9 II. PROCEDURAL HISTORY OF CONTENTION NYS-12C A. The Indian Point License Renewal Application and Original Contention NYS-12
4. On April 23, 2007, Entergy applied to the NRC to renew the Indian Point Unit 2 and Unit 3 (IP2 and IP3) operating licenses for twenty years beyond their current expiration dates of September 28, 2013, and December 12, 2015, respectively.10 As required by 10 C.F.R.

At the time the NRC imposed this requirements, only three facilities had considered severe accident mitigation alternatives in connection with their initial operating licenses (Limerick, Comanche Peak, and Watts Bar).

analysis for IP2 and IP3.12 As discussed in Section II.B below, Entergy later submitted a revised SAMA analysis for IPEC in December 2009.13

5. In preparing the IPEC SAMA analysis, Entergy used methodologies that have been used by numerous other license renewal applicants and that are consistent with those described in NRC-approved guidance.14 That guidance endorses using the MACCS2 computer code to estimate the offsite dose and economic impacts that result from postulated radioactive material releases to the environment.15 The Commission has described MACCS2, which is commonly used by license renewal applicants, as the most current, established code for NRC SAMA analysis.16
6. A SAMA analysis is part of the NRCs license renewal review under NEPA.17 SAMA analyses, however, do not represent the NRCs NEPA analysis of potential severe accident impacts.18 The NRCs GEIS for license renewal generically evaluates severe accident impacts and provides the technical basis for the NRCs conclusion in 10 C.F.R. Part 51 that the probability-weighted consequences of atmospheric releases, fallout onto open bodies of water, 12 See generally Indian Point Energy Center License Renewal Application, App, E, Applicants Environmental Report, Operating License Renewal Stage, Indian Point Energy Center at 4-47 to -78, E-I to E.4-82 (Apr.

releases to groundwater, and societal and economic impacts from severe accidents are small for all plants.19 The GEIS thus addresses the impacts of severe accidents generically in bounding fashion.20

7. By way of comparison, a SAMA analysis is a site-specific environmental mitigation analysis performed under NEPA.21 It is conducted to identify additional mitigation measuresprocedure or hardware changesthat may be cost-beneficial to implement at a nuclear power plant to further reduce the already very low risk (probability or consequences) of a severe accident.22 It also is a probabilistic risk assessment (PRA) because it examines the probability of various hypothesized accident scenarios, spanning a spectrum of potential initiating events, accident sequences, and severity of consequences.23 As a NEPA mitigation analysis, the SAMA analysis is judged under NEPAs rule of reason.24 As such, it is not based on best-case or worst-case accident scenarios.25 Rather, a SAMA analysis estimates mean accident consequence values (both offsite population dose and economic costs), which are averaged over many hypothetical severe accident scenarios and over the examined 50-mile radius region surrounding the plant.26 19 Id. at 5-115 (emphasis added).

26 Pilgrim, CLI-12-01, slip op. at 20. Specifically, [t]he analysis uses the mean values of the accident consequence distributions for each accident category. These mean values are multiplied by the estimated frequency of the accident to determine population dose risk and offsite economic cost risk for each release

8. On August 1, 2007, the NRC published a Notice of Acceptance for Docketing of the Application and Notice of Opportunity for Hearing, in the Federal Register.27 The Hearing Notice explicitly clarified that proposed contentions shall be limited to matters within the scope of [license renewal].28 It also stated that any person whose interest would be affected by the proceeding and who wished to participate as a party in the proceeding must file a petition for leave to intervene within sixty days of the Notice (i.e., October 1, 2007).29 On October 1, 2007, the Commission extended the period for filing requests for hearing until November 30, 2007.30
9. In response to the Hearing Notice, New York filed a petition to intervene on November 30, 2007, in which it proposed various contentions, including NYS-12, the contention at issue here.31 As originally proffered, NYS-12 alleged that Entergys SAMA analysis is deficient because MACCS2 underestimates the costs of a severe accident due to its use of decontamination and clean-up costs that are based on large-sized radionuclides.32 New York asserted that a nuclear power plant severe accident likely would result in the dispersion of small-sized radionuclides that are more expensive to clean-up than the large-sized radionuclide particles purportedly assumed in Entergys SAMA analysis.33 As principal support for this argument, New York cited the 1996 Site Restoration Report, which examined the potential category studied. Id. (citation omitted).Section IV.B of this decision discusses the SAMA analysis methodology in further detail.

economic costs that the federal government might face if weapons-related nuclear material in its custody became involved in an accident culminating in the release of plutonium to the environment.34 In particular, the report focused on the directly attributable costs that might be faced by the government in compensating property owners for loss or damage and in restoring an accident site.35

10. New York argued that the IPEC SAMA analysis should incorporate the analytical framework contained in the Site Restoration Report as well as recent studies examining the cost consequences of accidents in the New York metropolitan area.36 It claimed that the Site Restoration Report recognized that earlier estimates of decontamination costs are incorrect because they are based on studies of nuclear weapons that produce large particles.37
11. Entergy opposed the admission of NYS-12, arguing that it presented a generic challenge to the MACCS2 computer code used to perform the IPEC SAMA analysis, lacked adequate factual or expert opinion support, and failed to controvert specific portions of the license renewal application.38 The NRC Staff also opposed the admission of NYS-12. The Staff contended that New York had not established the relevance of the Site Restoration Report, noting that the report relates to the dispersion of plutonium from a nuclear weapon as opposed to radionuclide releases from a nuclear power plant severe accident.39 It also argued that New York 34 Site Restoration Report at viii (NYS000249) (emphasis added).

had failed to show how the MACCS2 code is defective, or how the Site Restoration Report presents a superior alternative or methodology.40

12. In reply, New York acknowledged that the Site Restoration Report focuses on nuclear weapon plutonium dispersal events, but maintained that the report is still a relevant source of information on post-accident decontamination costs.41 New York also disputed Entergys claims that NYS-12 is a generalized attack on the MACCS2 code, arguing that it instead focuses on particular aspects of the MACCS2 code that mis-represent the post-accident consequences of a severe accident, thus distorting the SAMA analysis of the damages such an accident would cause.42
13. The Board heard oral argument on whether NYS-12 and New Yorks other proposed contentions met the Commissions contention admissibility requirements on March 11, 2008, in White Plains, New York.43 Thereafter, on July 31, 2008, the Board admitted NYS-12 to the extent that it challenges the cost data for decontamination and cleanup used by MACCS2.44 In doing so, we stated that NYS-12 is neither a challenge to the acceptability of using the MACCS2 computer program nor a direct challenge to MACCS2 itself.45 Rather, we viewed the contention as questioning whether specific inputs and assumptions made in MACCS2 SAMA analyses are correct for the area surrounding Indian Point.46 40 Id. at 51.

B. The NRC Staffs Environmental Review and Amended Contentions NYS-12A/12B/12C

1. Draft Supplemental Environmental Impact Statement and Amended Contention NYS-12A
14. As required by NEPA and 10 C.F.R. Part 51, the NRC Staff comprehensively reviewed Entergys license renewal application. The NRC Staff initiated that process by publishing a notice of intent to prepare a plant-specific supplement to the GEIS (i.e., a supplemental environmental impact statement or SEIS) and to conduct related environmental scoping activities.47
15. As part of that process, the NRC Staff conducted environmental site audits at Indian Point from September 10-14, 2007, and from September 24-27, 2007, which allowed the NRC Staff to tour the site, examine the data Entergy used in preparing the ER, and meet with Entergy personnel and representatives from federal, state, and local government agencies to obtain relevant information.48
16. The NRC also invited the applicant, federal, state, local, and tribal government agencies, local organizations, and individuals to participate in the scoping process by providing oral comments at scheduled public meetings and/or submitting written suggestions and comments.49 The scoping process included two public meetings held on September 19, 2007, in Cortlandt Manor, New York.50 Following the NRC Staffs prepared statements, the meetings 47 Entergy Nuclear Operations, Inc., Indian Point Nuclear Generating Unit Nos 2 and 3; Notice of Intent to Prepare an Environmental Impact Statement and Conduct Scoping Process, 72 Fed. Reg. 45,075 (Aug. 10, 2007). 10 C.F.R. § 51.20(b)(2) requires the NRC to prepare an EIS or SEIS for renewal of a reactor operating license. In addition, Section 51.95(c) states that the EIS prepared at the operating license renewal stage will be a supplement to the GEIS (NYS00131A-I).

were open for public comments.51 The Staff received hundreds of written and oral comments during the scoping process.52

17. In addition to its participation in the adjudicatory process, New York also participated in the environmental scoping process. On October 31, 2007, New York submitted numerous comments concerning the scope of the IPEC Draft Supplemental Environmental Impact Statement (DSEIS) and various aspects of the NRC Staffs environmental review.53 In one comment, New York stated that the Staffs NEPA review should address whether the plume model used in the SAMA analysis is sufficiently accurate for use in computing the health and safety consequences of an accident, as an environmental issue.54 New York did not mention issues related to decontamination costs, as assessed by MACCS2 or in a SAMA analysis.
18. A month later, on November 30, 2007, New York supplemented its scoping comments, generally echoing the issues raised in proposed Contention NYS-12.55
19. Concurrently, the NRC Staff proceeded with its NEPA review. In preparing its DSEIS for IP2 and IP3, the NRC Staff reviewed the IPEC ER and compared it to the GEIS; consulted with numerous federal, state, regional, and local agencies, and Native American Tribes agencies (as listed in Appendix D to the DSEIS); conducted an independent review of the issues in accordance with the guidance in NUREG-1555 (the Staffs Environmental Standard Review 51 See id.

Plan for license renewal applications); issued to Entergy detailed requests for additional information (RAIs); and considered public comments received during the scoping process.56

20. Based on its initial review of the SAMA analysis, the Staff issued SAMA-specific RAIs to Entergy in December 200757 and April 2008.58 Entergy responded to the Staffs RAIs in letters dated February 5, 2008, and May 22, 2008.59 Entergys responses resulted in the identification of several additional potentially cost-beneficial SAMAs as well as the elimination of one previously-identified cost-beneficial SAMA.60

Relevant here, in SAMA RAI 4, the Staff requested that Entergy briefly describe key MACCS2 input assumptions that contribute to the offsite economic cost risk, including the non-farm area decontamination cost input, and to [j]ustify that the input values used for these parameters are reasonable for the Indian Point site/region.61 As discussed further below, 56 See NUREG-1437, Supp. 38, Generic Environmental Impact Statement for License Renewal of Nuclear Plants, Regarding Indian Point Nuclear Generating Unit Nos. 2 and 3, Draft Report for Comment at xiii (Dec. 2008)

61 February 2008 RAI Response, Attach. 1 at 22 (ENT000460).

Entergy responded to the Staffs RAI in its February 2008 RAI Response.62 Entergy explained that its MACCS2 decontamination inputs are reasonable for the IPEC SAMA analysis region, because they are derived from well-established, reliable values contained in NRC guidance documents (NUREG-1150 and NUREG/CR-4551), and are based upon various levels of contamination and site-specific population estimates.63 Entergy further stated that some portions of the IPEC SAMA analysis region have relatively high population densities, whereas other areas have relatively low population densities (e.g., due to the high proportions of local, state and federal parkland and other rural property).64 Therefore, Entergys MACCS2 input values actually reflect local conditions.

22. In December 2008, the Staff issued the DSEIS for public comment.65 The Staff documented its initial review of Entergys SAMA analysis in Section 5.2 and Appendix G of the DSEIS. Among other things, the Staff concluded that certain MACCS2 inputs, including the population relocation cost, daily cost for a person who is relocated, and cost of farm and nonfarm decontamination were obtained from the MACCS2 Code Manual and inflation-adjusted using the consumer price index corresponding to the year 2005.66 The Staff also concluded that Entergys MACCS2-based methodology provides an acceptable basis for assessing the risk reduction potential for candidate SAMAs because the key elements of the methodology are consistent with standard practice.67 62 See id., Attach. 1 at 37-38 (ENT000460).

23. Subsequently, it held two public meetings in Cortlandt Manor, New York, on February 12, 2009. During those meetings, the Staff described the preliminary results of the NRC environmental review (as documented in the DSEIS), answered questions, and provided members of the public with information to assist them in formulating comments on the DSEIS.68 During the DSEIS comment period, the Staff received comments from 183 individuals or groups, including New York, and 88 commenters spoke during the public meetings.69 In a comment submitted on the DSEIS, New York asserted that as part of its analysis, the NRC Staff should consider the densely populated and developed New York City area, incorporate the regions property values, and ensure that the resulting financial costs are expressed in present value.70 New York again asserted that the NRC Staff should use the analytical framework contained in the 1996 Site Restoration Report.71
24. After reviewing the DSEIS, New York submitted Contention NYS-12A, which asserted that the DSEIS adopted the same flawed modeling contained in the ER and, therefore, also underestimated the true cost of decontamination and cleanup in the event of a severe accident.72 NYS-12A mirrored New Yorks above-described comments on the DSEIS.73 Thus, New York again asserted that the Staff should consider the densely populated and developed New York City area, incorporate the regions property values, and use the analytical framework contained in the 1996 Site Restoration Report.74 68 See FSEIS, Vol. 1 at xvi (NYS00133A).

25. In its Answer, Entergy asserted that New York had not met the requirements of 10 C.F.R. § 2.309(f)(2) for the admission of an amended contention, because it did not allege that the DSEIS contains data or conclusions that are significantly different from those in Entergys ER.75 The NRC Staff did not oppose the admission of the amended contention, insofar as it simply recast NYS-12 as challenge to the DSEIS.76
26. We admitted NYS-12A on June 16, 2009, and consolidated it with NYS-12,77 finding no issue with [New York] proactively asking the Board to recognize that an admitted contention relative to the ER challenges the same issue when included in the Draft SEIS.78
2. Entergys Revised SAMA Analysis and Amended Contention NYS-12B
27. Later, in November 2009, as part of its ongoing environmental review, the Staff sought clarification from Entergy regarding certain wind direction data as an input to the MACCS2 code.79 In addressing the Staffs inquiry, Entergy determined that the 5-year averaged wind direction data used in the original SAMA analysis were not representative of the regions wind direction conditions for the five-year period (2000-2004) originally considered by Entergy.80 Entergy submitted a revised SAMA analysis in December 2009 that addressed the Staffs concern by using a single, representative year of meteorological data; i.e., 2000.81 75 Answer of Entergy Nuclear Operations, Inc.

81 See id. Entergy selected the year 2000 because, of the five years of data used in the original analysis, the year 2000 resulted in the most conservative (i.e., largest) calculated population doses. Id. The use of one year of meteorological data is permitted by NEI 05-01. See NEI 05-01 at 15 (NYS000287) (stating that an applicant may use a full year of consecutive hourly values). In its revised SAMA analysis, Entergy used the same 2035 population estimate at issue in a separate New York contention, NYS-16B. See NL-09-065, Attach. 1 at

28. New York filed Amended Contention 12B as a challenge to Entergys revised SAMA analysis.82 NYS-12B contended that Entergys revised SAMA analysis underestimated the likely decontamination and cleanup costs associated with a postulated severe accident at IPECthe same allegation made in NYS-12 and NYS-12A.83 New York reiterated its view that Entergy and the Staff should have used decontamination cost information contained in the Site Restoration Report.84
29. Entergy and the NRC Staff filed Answers. Entergy continued to assert its disagreement with NYS-12/12A on the merits, but did not oppose admission of NYS-12B insofar as the amended contention simply reasserted claims that the Board already admitted as NYS-12/12A, and NYS-12B relied on the same evidence as the previously admitted contention.85 The NRC Staff also did not oppose the admission of NYS-12B.86 It noted that New Yorks supporting bases were substantially identical to New Yorks supporting bases for NYS-12 and NYS-12A, albeit modified to refer specifically to Entergys revised SAMA analysis.87 5 (ENT000009). NYS-16B claims that the FSEIS improperly accepts Entergys estimate of the 2035 population within 50 miles of IPEC, despite two alleged errors in Entergys estimate: (1) failure to account for census undercount of minority and low-income groups in the 2000 U.S. Census data underlying the estimate, and (2) failure to account for the commuter population within the 50-mile radius region surrounding IPEC.

3. Final Supplemental Environmental Impact Statement and Amended Contention NYS-12C
31. The NRC Staff issued its FSEIS in December 2010, which consists of three volumes and over 2,000 pages.89 In the FSEIS, the Staff considered and addressed all public comments on the scope of the Staffs NEPA review and its DSEIS.90 Appendix A to the FSEIS documents the Staffs responses to those comments.91
32. New Yorks submission of the aforementioned comments and related contention (as subsequently amended) is expressly reflected in Appendix A to the FSEIS:

A concern regarding the adequacy of the decontamination cost estimates used in the SAMA analysis was raised in a contention filed by the State of New York in the license renewal adjudicatory proceeding. The contention includes the criticisms mentioned above and has been admitted for litigation by the ASLB. Additional discussion of the decontamination cost estimates and their impact on the SAMA analysis has been provided in Section G.2.3 of Appendix G to the FSEIS.92 Thus, it is clear that in the FSEIS, the NRC Staff explicitly acknowledged and analyzed Entergys MACCS2 decontamination cost inputs and New Yorks criticism thereof, the same overarching criticism raised in Contention NYS-12/12A/12B.

33. FSEIS Section G.2.3 documents the NRC Staffs detailed evaluation of the IPEC SAMA analysis, including the methods used in those analyses and the results.93 As stated therein, the Staff utilized the relevant technical expertise of Sandia MACCS2 and decontamination specialists (including Staff witnesses Dr. Bixler and Mr. Jones) in performing its review.94
34. The NRC Staff concluded in the FSEIS that Entergys methodology provides an acceptable basis from which to proceed with an assessment of candidate SAMAs.95 It further concluded that Entergys decontamination cost estimates are reasonable and acceptable, and consistent with those used in SAMA analyses performed for other nuclear power plants and previously accepted by the NRC.96
35. As noted above, in FSEIS Section G.2.3, the NRC Staff also included a new technical analysis that directly addresses allegations made in New Yorks contention.97 The Staff, addressing the Site Restoration Report, stated that it does not consider the methodology for clean-up of a nuclear weapons accident relevant to the decontamination and clean-up after a nuclear power plant severe accident.98 Nonetheless, the Staff and its Sandia analysts reviewed the inputs and assumptions regarding particle size distribution and decontamination costs used in the IPEC SAMA analysis, and compared the decontamination cost factors derived from the 1996 Site Restoration Report cited by New York to those used in the IPEC SAMA analysis.99 93 Id. at 5-1 to 5-13; Id., App. G at G-1 to G-51.

The FSEIS states that the NRC Staff and Sandia performed a comprehensive review of relevant documents and references, including the ER, the DSEIS, the MACCS2 input decks for Indian Point and associated documentation, the New York contentions and supporting documents and references, the Boards rulings on the contentions, and other relevant filings in the adjudicatory proceeding. See id. at G-22.

36. As described in the FSEIS, the NRC Staff and Sandia identified the basic considerations of a nuclear weapons and a reactor accident (e.g., contaminants, half life of contaminants, and health and safety considerations), identified the decontamination methods required to cleanup each type of accident, and compared the Site Restoration Report cost values (as applied to the urban area of New York City) to those used in the IPEC SAMA analysis.100 Based on this review, the NRC Staff and Sandia concluded that Entergys decontamination cost estimates are reasonable, acceptable, and consistent with the estimates used in prior NRC-approved SAMA analyses for other nuclear power plants.101
37. New York filed Amended Contention NYS-12C, the last amendment to its contention, in response to the December 2010 FSEIS.102 In addition to updating its previously-admitted consolidated contentions (NYS-12/12A/12B), New York also sought to challenge the discussion in FSEIS Section G.2.3 insofar as it applies to those contentions.103 In particular, New York, based on a report prepared by its former consultant, Mr. David Chanin,104 argued that the FSEIS is inadequate because it: (1) accepts and applies cost data for moderate contamination events in lieu of cost data for heavy contamination events; and (2) fails to scale up the Site Restoration Report decontamination cost data, which New York alleged are based 100 See id. at G-23.

38. In its Answer, Entergy did not oppose New Yorks characterization of NYS-12C as an update to NYS-12/12A/12B, or New Yorks incorporation by reference of supporting evidence previously identified by New York in support of those contentions.106 However, Entergy opposed the admission of NYS-12C,107 asserting that New Yorks then-consultant, Mr.

Chanin, relied on several technical papers concerning the economic costs of rad/nuc attacks using nuclear weapons or dirty bombs.108 According to Entergy, New York did not demonstrate the relevance of those papers to a nuclear power plant SAMA analysis.109 Entergy further asserted that New York had not raised a genuine dispute of material fact with the FSEIS because: (1) the radionuclides postulated in the FSEIS are in fact small, and radionuclides similar to those used in the IPEC SAMA analysis have been found acceptable for other plants SAMA analyses; (2) Mr. Chanins report contradicted FSEIS conclusions regarding clean-up costs from plutonium and cesium dispersal; (3) there is no technical reason to require a higher 105 See id. at 7.

109 Entergy Answer to NYS-12C at 3. Entergy did not oppose NYS-12C on timeliness grounds, insofar as that contention sought to challenge the new discussion contained in Section G.2.3 of the FSEIS. However, Entergy expressly reserved any arguments or objections that might exist relative to the timeliness of New Yorks reliance on the three technical reports cited by Mr. Chanin, the most recent of which was published in February 2008. Id. at 17 n.90. Entergy asserted that New York could have identified those documents as supporting references for its contention as early as February 2009, when it filed NYS-12A in response to the DSEIS. Id.

Part 51.110

39. The Staff did not oppose NYS-12C to the extent that it sought to apply Contention 12/12A/12B to the FSEIS discussion of the IPEC SAMA analysis.111 The Staff, however, opposed the admission of NYS-12C in all other respects.112 It argued that NYS-12C: (1) relies upon information which was available to New York before the issuance of the FSEIS, and fails to satisfy the timeliness requirements set forth in 10 C.F.R. §§ 2.309(c)(1) and 2.309(f)(2);113 (2) is overly vague and lacking in basis, contrary to 10 C.F.R. § 2.309(f)(1)(ii);114 and (3) fails to raise a genuine material issue in dispute, as required by 10 C.F.R. § 2.309(f)(1)(iv) and (vi).115
40. We admitted NYS-12C and consolidated it with NYS-12/12-A/12-B as Consolidated Contention NYS-12C.116 In doing so, we emphasized that NYS-12Cs claims regarding the sufficiency of Entergys and the NRC Staffs SAMA reviews mirror the basic allegation found in the consolidated contention that NYS-12C seeks to amend; i.e., that Entergys and the NRC Staffs use of the MACCS2 code leads to an underestimation of the cleanup costs from a severe accident.117 We further explained that this overarching aspect of 110 See id. at 22-25.

Lemay, alleged that Entergys SAMA analysis significantly underestimates the economic costs of a severe accident at IPEC by relying on MACCS2 code input values that purportedly are not IPEC-specific and do not account for the particle types released from such an accident.122 In this regard, they principally asserted that: (1) the use of the MACCS2 Users Guide Sample Problem A inputs in lieu of site-specific inputs results in underestimated severe accident costs, because the Sample Problem A inputs are not current and are not appropriate for the dense population and buildings surrounding IPEC;123 (2) the decontamination factors and times used by Entergy and accepted by the NRC Staff are not rationally related to IPEC;124 and (3) the nonfarm decontamination cost input data used by Entergy and accepted by the Staff is not rationally related to IPEC.125 As described in his testimony and associated expert report,126 Dr.

Lemay proposed alternative values for various MACCS2 input parameters that the Board discusses in detail below.

42. Entergy filed a Motion in Limine to exclude certain portions of Dr. Lemays testimony, report, and supporting exhibits on the ground that New Yorks prefiled testimony discussed issues and challenged MACCS2 parameters beyond the scope of the admitted contention.127 Entergy asserted that, as pled and admitted, NYS-12C challenged only the adequacy of Entergys nonfarm decontamination cost value (MACCS2 input parameter CDNFRM), principally related to information contained in the Site Restoration Report and other studies cited by New York.128 Entergy contended that Dr. Lemays testimony improperly disputed numerous other Entergy MACCS2 inputs not previously challenged by New York.129
43. Entergy also viewed Dr. Lemays objections to Entergys use of MACCS2 Users Guide Sample Problem A values as a belated new argument.130 Finally, Entergy moved to strike Dr. Lemays testimony and report insofar as they relied on results generated using a modified version of the proprietary MACCS2 code.131 Specifically, Dr. Lemay modified the MACCS2 source code to accept larger non-farm decontamination cost (CDNFRM) and decontamination time (TIMDEC) values than would otherwise be allowed by the code.132 127 Applicants Motion in Limine to Exclude Portions of the Prefiled Testimony, Report, and Exhibits Filed by New York State and Dr. Francois Lemay in Support of Consolidated Contention NYS-12C (Jan. 30, 2012),

44. The NRC Staff supported Entergys Motion in Limine.133 In its Answer, the Staff asserted that New York and its original consultant (Mr. Chanin) had identified only two alleged errors in the FSEIS,134 and that Dr. Lemays testimony, report and supporting exhibits stray far from these two discrete issues.135 The Staff also contended that the Dr. Lemays uncontrolled changes to the MACCS2 code were not limited to the issue identified in New Yorks contention, such that the Board should exclude any related testimony.136 New York opposed Entergys Motion in Limine.137
45. We denied Entergys Motion in Limine noting that licensing boards admit contentions, not bases, and finding that the additional contested MACCS2 inputs go to the core of the question of property values and how they might be affected by a radionuclide-releasing accident at IPEC and the resulting decontamination process.138 We further noted that Dr.

Lemays MACCS2 source code modifications illustrate the effect of varying the codes assumptions to address alternative inputs, as conceptualized by the original admitted contention.139 Finally, the Board reiterated its prior ruling that the contention is not challenging 133 See NRC Staffs Answer to Applicants Motion in Limine to Exclude Portions of the Prefiled Testimony, Report, and Exhibits Filed by New York State and Dr. Francois Lemay in Support of Consolidated Contention NYS-12C (Feb. 9, 2012), available at ADAMS Accession No. ML12040A239.

According to the Staff, Mr. Chanin had asserted that in the FSEIS, the Staff (1) relied on cleanup costs estimates for a city with 1,344 person/km2 and made no adjustment to New York City, with its assumed 12,000 persons/km2; and (2) mistakenly claimed that cleanup costs for moderate contamination requiring a DF from 5 to 10 for plutonium is appropriate for achieving a DF of 15 for cesium.

the use of MACCS2 itself, but is questioning whether specific inputs and assumptions made in MACCS2 SAMA analyses are correct for the area surrounding Indian Point.140 D. Entergys and the NRC Staffs March 2012 Prefiled Testimony

46. Entergy filed its Statement of Position141, written testimony142, and supporting exhibits for contention NYS-12C on March 30, 2012.143 Entergy submitted written testimony from a panel of three witnesses: Ms. Lori Potts, Dr. Kevin OKula, and Mr. Grant Teagarden.144
47. In response to New Yorks direct testimony, Entergys experts testified that Entergy followed the NRC-approved, prescriptive guidance in NEI 05-01 to perform the SAMA analysis and appropriately used the NRC and industry standard code (MACCS2) in the analysis.145 In addition, they testified that Entergys MACCS2 decontamination cost and time inputs are reasonable and appropriate for use in a NEPA-based SAMA analysis.146 They explained that Entergys values, while coinciding with Sample Problem A values, are actually:

(1) based on peer-reviewed NUREG-1150 values that have been well-vetted by the nuclear industry, the national laboratories, and the NRC;147 (2) used in all NRC-approved SAMA analyses;148 and (3) applied in the NRCs recent State-of-the-Art Reactor Consequence Analyses 140 Id.

48. The NRC Staff also filed its Statement of Position153, written testimony154, and supporting exhibits for contention NYS-12C on March 30, 2012.155 The Staff filed testimony from a panel of four witnesses: Dr. Nathan Bixler, Dr. S. Tina Ghosh, Mr. Joseph Jones, and Mr.

Donald Harrison.156

49. The Staffs witness Dr. Bixler and Dr. Ghosh testified that NYS-12C does not raise valid issues that would materially impact the IPEC SAMA analysis.157 Among other things, they asserted that: (1) New York incorrectly claims that the SAMA analysis assumes unrealistically large particles, and that accounting for smaller particle sizes would result in 149 See id. at 13 (A26), 85-86 (A106).

greater cleanup costs;158 (2) the Site Restoration Report is inappropriate for modeling the clean-up costs from a reactor severe accident given the significant differences between cleanup of plutonium dispersal accidents and the isotopes resulting from a severe nuclear reactor accident;159 (3) MACCS2 provides a reasonable analytical framework to compute offsite economic costs in a SAMA analysis;160 (4) Entergy used appropriate site-specific and standardized MACCS2 inputs in the SAMA analysis;161 (5) the IPEC SAMA analysis accounted for the unique characteristics of New York City through the application of population-based cost parameters;162 and (6) the decontamination costs and times used by Dr. Lemay tend to be biased toward the worst accident scenarios and for the worst environmental conditions.163 E. New Yorks June 2012 Prefiled Rebuttal Testimony and Related Motions

50. On June 29, 2012, New York filed its Revised Statement of Position164, written rebuttal testimony165, and several new exhibits referenced therein.166 Therein, New York and Dr.

Lemay asserted, in principal part, that the central issue raised by NYS-12C is whether it was reasonable for Entergy and NRC Staff to rely upon Sample Problem A inputs instead of developing site-specific inputs for IPEC.167 They argued that NUREG-1150s technical pedigree does not justify the use of the MACCS inputs contested by New York, and that the 158 See id. at 48-51 (A41-45), 52-57 (A48-49).

NUREG-1150 values appear to be based on a draft document that was never published.168 New York and Dr. Lemay further claimed, for the first time, that in the 1980s the NRC commissioned a site-specific case study (i.e., Chapter 5 of Draft NUREG/CR-5148) to estimate the costs associated with a severe accident at Indian Point.169 According to New York, it was unreasonable for the NRC Staff to rely on NUREG-1150 values, given that a specific analysis was eminently possible and had been completed in conjunction with [Draft] NUREG/CR-5148.170

51. Entergy filed a Motion seeking leave from the Board to file written surrebuttal testimony and a revised position statement on NYS-12C.171 In support of its Motion, Entergy argued that it was prejudiced by New Yorks presentation of new arguments and evidence that exceeded the scope of rebuttal testimony, and to which Entergy did not have a fair opportunity to respond.172 In particular, Entergy objected to New Yorks reliance on Draft NUREG/CR-5148, and its related new argument that the draft report documented an Indian Point-specific case study.173 The Staff did not oppose Entergys Motion but did not file an Answer.174
52. The Board denied Entergys motion for leave to file surrebuttal testimony on contention NYS-12C.175 We ruled that the issues raised in the motion could be handled at the 168 See New York Rebuttal Testimony at 19:16-25:4 (NYS000420).

53. In the interim, on July 30, 2012, Entergy and the NRC Staff filed separate Motions in Limine seeking to exclude portions of Dr. Lemays rebuttal testimony (NYS000420),

Exhibits NYS000424178 and NYS000426,179 and related portions of New Yorks Revised Position Statement (NYS000419).180 They argued that the testimony and exhibits in question should be excluded from evidence because they belatedly advanced new arguments that Entergy and the Staff could not have reasonably anticipated when they prepared their prefiled direct testimony.181 Entergy and the Staff also challenged the new testimony and evidence as unreliable and not relevant under the evidence admissibility standards in 10 C.F.R. § 2.337(a).182 The Board later denied both Motions in Limine in a bench ruling issued on October 15, 2012, the first day of evidentiary hearings, opting instead to accord the challenged testimony and evidence its due weight after the hearing on the merits.183 176 See id.

F. Other Prehearing Procedural Matters

54. On August 8, 2012, New York filed a motion with respect to its seven Track 1 contentions,184 seeking to invoke its purported statutorily-granted cross-examination rights under Section 274(l) of the Atomic Energy Act (AEA), 42 U.S.C. § 2021(l).185 Specifically, New York claimed that as the host state to IPEC, Section 274(l) confers upon it expansive cross-examination rights that take precedence over the restrictive cross-examination rights allowed pursuant to 10 C.F.R. §§ 2.315(c) and 2.1204(b)(3).186 It argued that the 2004 modifications to the NRCs Administrative Procedure Act-compliant regulations, which it contended generally restrict the use of cross-examination by most parties, do not purport to address the rights preserved to the States in [Section 2021(l)].187 Thus, New York asserted, 10 C.F.R. §§ 2.135(c) and 2.1204(b)(3) do not apply to it as a host state and do not restrict its right to interrogate witnesses.188
55. Both Entergy and the NRC Staff opposed the motion as lacking a legal basis,189 arguing that New York mischaracterized as an absolute right what is actually a reasonable opportunity to cross-examine witnesses.190 184 Track 1 contentions consist of Riverkeeper TC-2 (Flow-Accelerated Corrosion), NYS-12C (SAMA Analysis -

Decontamination Costs), NYS-16B (SAMA Analysis - Population Estimate), NYS-17B (Land Values), NYS-37 (Energy Alternatives), Clearwater EC-3A (Environmental Justice), NYS-5 (Buried Piping), NYS-6/7 (Non-EQ Cables), and NYS-8 (Transformers). Prior to the October 2012 hearings, the parties settled another Track 1 contention, Riverkeeper EC-3/Clearwater EC-1 (Spent Fuel Pool Leaks to Groundwater). The Board approved that settlement agreement on October 17, 2012.

56. On August 29, 2012, in accordance with 10 C.F.R. § 2.1207(a)(3) and the Boards Scheduling Order, Entergy (and the other parties) submitted in camera proposed questions for the Board to consider asking to the other parties witnesses on Contention NYS-12C.191
57. In an Order issued on September 21, 2012, the Board granted, in part, New Yorks August 8, 2012 motion for cross-examination of witnesses during the evidentiary hearings.192 The Board found that New Yorks opportunity to cross-examine witnesses is bound by the same 10 C.F.R. Part 2 regulations that govern all parties to this proceeding.193 As a result, the Board found it unnecessary to address whether and if so to what extent, in some theoretical sense, the right to cross-examination granted to host states by the AEA may be different from those provided to parties under 10 C.F.R. Part 2.194 Citing 10 C.F.R. § 2.1204(b)(1), the Board noted that in any oral hearing held under Subpart L, a party may file a motion (accompanied by a cross-examination plan) seeking cross-examination by the parties on particular admitted contentions or issues.195 Pursuant to 10 C.F.R. § 2.1204(b)(3), the presiding officer may allow cross-examination by the parties only if the presiding officer determines that cross-examination by the parties is necessary to ensure the development of an adequate record for decision.196
58. The Board concluded that New York had complied with 10 C.F.R. § 2.1204(b) by filing the motion for cross-examination and proposed examination questions before the August 190 Entergy Answer Opposing New York Motion at 3-4, Staff Answer Opposing New York Motion at 9-10.

59. On September 24, 2012, the Board discussed its Order in a pre-hearing conference call in response to questions from the NRC Staff and Entergy.200 During that conference, Chairman McDade confirmed that New York would have the opportunity to examine witnesses on areas that the Board missed in its own witness examinations.201 He also suggested that the Board might limit New Yorks questioning if it becomes repetitive202 and stated that other parties would have a reasonable opportunity to interrogate witness on discrete issues through oral motions at the hearing if they made a sufficiently compelling request and avoided repetitive questions.203
60. Subsequently, on September 28, 2012, Entergy filed an emergency petition for interlocutory review of the Boards order with the Commission.204 Entergy requested, and was 197 Id.

granted, expedited briefing on its petition.205 New York opposed Entergys petition206 and the Staff supported it.207

61. On October 12, 2012, the Commission issued an Order denying Entergys request for interlocutory review, noting that the Board has the responsibility in the first instance to oversee the development of an adequate case record.208 In so ruling, the Commission cited Chairman McDades assurances, made during the September 24, 2012 prehearing conference call, that the Board would prohibit open-ended, lengthy, repetitive, and immaterial cross-examination, and allow all parties a full and fair opportunity to request cross-examination.209 The Commission further stated its expectation that the Board would act on cross-examination requests fairly and evenhandedly, rigorously oversee any cross-examination it allowed, and limit the cross-examination to supplemental and genuinely material inquiries, necessary to develop an adequate and fair record.210
62. During the hearing on the first contention (Riverkeeper TC-2), the Board indicated that it would allow questioning of the witnesses by the petitioner (there, Riverkeeper, Inc. (Riverkeeper)), Entergy, and the NRC Staff.211 Entergy objected to examination of witnesses by any party, and requested that the Board close the record on that contention.212 In 205 Id.; Commission Order (Oct. 2, 2012) (unpublished).

support, Entergy: (a) noted that Riverkeeper had not made, nor been required to make, the sort of showing contemplated by the Subpart L regulations, which was a circumstance that the Commission had found troubling; (b) argued that no sufficient constraints had been placed on examination by parties; (c) noted that the procedure, rather than constituting the rare occurrence contemplated by the Commission, was apparently being undertaken as the norm for these proceedings; and (d) argued that, with two full days of Board questioning, additional questioning by the parties was not truly necessary, as mandated by the Commission.213 In the alternative, Entergy requested reciprocal treatment; i.e., that it be afforded the same direct and cross-examination rights as the other parties.214

63. The Board denied Entergys motion to preclude party examination of witnesses, stating any additional showing need not be articulated, and that the Board envisioned allowing Riverkeeper, then Entergy, and then the Staff brief opportunities to conduct limited interrogation of the witnesses.215 During hearing on NYS-12C (the second contention), Entergy reiterated its objection, which was again denied by the Board, and Entergy asked that the Board recognize Entergys standing objection on such grounds with respect to all remaining contentions.216 Upon that basis, Entergy rested upon its standing objection, and did not repeat its procedural arguments in connection with subsequent contentions.

G. The October 17-18, 2012 Evidentiary Hearings

64. On October 15, 2012, the Board commenced evidentiary hearings on the Track 1 contentions and admitted into evidence the exhibits proffered by the parties.217 The Board held evidentiary hearings on Contention NYS-12C on October 17-18, 2012 at the DoubleTree Hotel in Tarrytown, NY, located at 455 South Broadway, Tarrytown, NY 10591.218
65. The Board conducted the hearing in accordance with the provisions of 10 C.F.R.

Part 2, Subpart L. In accordance with our September 21, 2012 Order, and the Commissions related guidance in CLI-12-18, the Board permitted limited cross-examination and redirect examination by all parties. Specifically, after the Board completed its questioning of the parties witnesses, it afforded all parties the opportunity to ask relevant, non-repetitive redirect and cross-examination questions to the witnesses.219 New York questioned the witnesses first, followed by Entergy and then the NRC Staff.220

66. After the conclusion of the hearing, the parties jointly submitted proposed corrections to the hearing transcripts on December 5, 2012.221 The Board issued an Order on December 27, 2012, adopting the parties proposed transcript corrections with some minor revisions.222
67. On March 22, 2013, the parties submitted proposed findings of fact and conclusions of law in the form of a proposed Initial Decision by the Board.

III. APPLICABLE LEGAL AND REGULATORY STANDARDS A. Law Governing Environmental Evaluations and SAMA Analyses Under NEPA

68. Two sets of regulatory requirements govern the NRCs review of license renewal applications. Under 10 C.F.R. Part 54, the NRC conducts a health and safety review focused on the detrimental effects of aging on the plant.223 Under 10 C.F.R. Part 51, the NRC completes a NEPA-based environmental review, focusing on the potential impacts of twenty additional years of operation. As explained above, the contention at issue hereNYS-12Carises under NEPA and the NRCs NEPA-implementing regulations in 10 C.F.R. Part 51.224
69. NEPA requires that federal agencies, such as the NRC, prepare an EIS for major Federal actions significantly affecting the quality of the human environment.225 NEPA is a procedural statute that does not mandate particular substantive results.226 Rather, it is designed to insure a fully informed and well-considered decision in the examination of potential environmental impacts of a proposed agency action.227 NEPA merely prohibits uninformed rather than unwiseagency action.228
70. Under NEPA, the Board must apply a rule of reason in determining whether the NRC took the requisite hard look at the proposed actions environmental impacts and alternatives.229 Under the rule of reason, an EIS need not be so all-encompassing in scope that the task of preparing it would become either fruitless or well nigh impossible.230 An EIS must 223 See Nuclear Power Plant License Renewal: Revisions, 60 Fed.

only furnish such information as appears to be reasonably necessary under the circumstances for evaluation of the project.231

71. As the Commission explained in Pilgrim, NEPA does not require agencies to use the best scientific methodology, and NEPA should be construed in the light of reason if it is not to demand virtually infinite study and resources.232 The Commission clarified that an EIS is not intended to be a research document, reflecting the frontiers of scientific methodology, studies and data.233 Nor does NEPA require agencies to use technologies and methodologies that are still emerging and under development, or to study phenomena for which there are not yet standard methods of measurement or analysis.234 Moreover, while there will always be more data that could be gathered, agencies must have some discretion to draw the line and move forward with decisionmaking.235 In short, the Commission explained, NEPA allows agencies to select their own methodology as long as that methodology is reasonable.236
72. [N]or does NEPA require [resolution of] disagreements among various scientists as to methodology.237 When specialists express conflicting views, an agency must have discretion to rely on the reasonable opinions of its own qualified experts.238 B. Legal Principles Applicable to SAMA Contentions
73. In the past several years, the Commission has issued a series of rulings that bear directly on the issue of adjudicatory challenges to SAMA analyses. For example, in the Pilgrim 231 Lee v. U.S. Air Force, 354 F.3d 1229, 1245 (10th Cir. 2004).

proceeding (CLI-12-01), the Commission recently stated that, unless a contention, submitted with adequate factual, documentary, or expert support, raises a potentially significant deficiency in the SAMA analysisthat is, a deficiency that could credibly render the SAMA analysis altogether unreasonable under NEPA standardsa SAMA-related dispute will not be material to the licensing decision, and is not appropriate for litigation in an NRC proceeding.239

74. In addition, the Commission stated in Seabrook (CLI-12-05) that, [g]iven the quantitative nature of the SAMA analysis, where the analysis rests largely on selected inputs, it may always be possible to conceive of alternative and more conservative inputs, whose use in the analysis could result in greater estimated accident consequences.240 As the Commission noted, however, the proper question is not whether there are plausible alternative choices for use in the analysis, but whether the analysis that was done is reasonable under NEPA.241 That is because SAMA adjudications would prove endless if hearings were triggered merely by suggested alternative inputs and methodologies that conceivably could alter the cost-benefit conclusions.242 Significantly, the Commission held that [a] contention proposing alternative inputs or methodologies must present some factual or expert basis for why the proposed changes in the analysis are warranted (e.g., why the inputs or methodology used is unreasonable, and the proposed changes or methodology would be more appropriate).243 Otherwise, as the Commission explained, there is no genuine material dispute with the SAMA analysis that was 239 Pilgrim, CLI-12-01, slip op. at 25; see also id.

done, only a proposal for an alternate NEPA analysis that may be no more accurate or meaningful.244

75. Thus, the fact that a computer model (MACCS2 in this case) could have been run with alternate inputs (e.g., nonfarm decontamination cost values) does not, by itself, suggest that the inputs used were unreasonable.245 As the Commission recently held in Pilgrim (CLI-12-15),

contentions challenging a SAMA analysis must identify a deficiency that plausibly could alter the overall resultsi.e., the conclusions as to which SAMAs may be cost-beneficialin a material way.246 C. Standard of Review and Burden of Proof

76. The Board reviews contested issues de novo.247 According to the Commission:

[W]hen resolving contentions litigated through the adversary process, [boards must] bring their own de novo judgment to bear. In such cases, boards must decide, based on governing regulatory standards and the evidence submitted, whether the applicant has met its burden of proof (except where the NRC Staff has the burden).248

77. With respect to NYS-12C, New York has the initial burden of going forward; i.e., it must provide sufficient evidence to support the claims made in the admitted contention.249 244 Id.

Once he has introduced sufficient evidence to establish a prima facie case, the burden then shifts to the applicant who, as part of his overall burden of proof, must provide a sufficient rebuttal to satisfy the Board that it should reject the contention as a basis for denial of the permit or license.)

If it does so, then the burden shifts to the applicant and the NRC Staff to provide sufficient evidence to rebut the intervenors contention.251 In challenging the NRC Staffs SAMA evaluation, it is the petitioners burden to provide support for why the further analyses or new computer modeling it seeks credibly could make a material difference to the SAMA analysis conclusions, not simply that the analysis might change in some fashion.252

78. An applicant generally has the burden of proof in a licensing proceeding.253 In cases involving NEPA contentions, the burden shifts to the NRC Staff, because it has the burden of complying with NEPA.254 The Commission has described that burden as follows:

Ultimately, NEPA requires the NRC to provide a reasonable mitigation alternatives analysis, containing reasonable estimates, including, where appropriate, full disclosures of any known shortcomings in available methodology, disclosure of incomplete or unavailable information and significant uncertainties, and a reasoned evaluation of whether and to what extent these or other considerations credibly could or would alter the [applicants]

79. Although the Staff must perform an independent review under NEPA, the Staff understandably relies upon the applicants ER in preparing the SEIS.256 Therefore, should the Applicant become a proponent of a particular challenged position set forth in the EIS, the Applicant, as such a proponent, also has the burden on that matter.257
80. From an evidentiary standpoint, the Applicants and NRC Staffs positions must be supported by a preponderance of the evidence.258 If the preponderance of the evidence shows that the Applicants and Staffs positions with respect to the contested issues are reasonable, then the Board will rule in their favor.

D. The Boards Decision Supplements and Amends the FSEIS

81. In accordance with these NEPA and administrative law principles, NRC hearings must focus on whether the NRC Staff has taken the required hard look at relevant, non-speculative environmental impacts.259 Thus, NRC hearings must focus on whether Staff has unduly ignored or minimized pertinent environmental effects.260 But it is not a game of 256 See 10 C.F.R. § 51.45(c) (The environmental report should contain sufficient data to aid the Commission in its development of an independent analysis.); id. § 51.70(b) (The NRC staff will independently evaluate and be responsible for the reliability of all information used in the draft environmental impact statement.).

82. In determining whether the environmental record in this proceeding is sufficient under NEPA and 10 C.F.R. Part 51, the Board considers the record as a whole, including the FSEIS and the evidentiary record for the hearing, as developed by the Board and the parties.262 As the Commission has explained:

Boards frequently hold hearings on contentions challenging the staffs final environmental review documents. In such cases,

[t]he adjudicatory record and Board decision (and . . . any Commission appellate decisions) become, in effect, part of the FEIS. Put another way, under our longstanding practice, the Staffs review (the FEIS itself) and the adjudicatory record will become part of the environmental record of the decision.263

83. Thus, after the Board considers the entire record of this proceeding, the FSEIS will be deemed supplemented by the Boards decisions on NEPA contentions and by any subsequent Commission decision.264 Likewise, the NRCs record of decision ultimately will include the Board and Commission decisions, which are based on the adjudicatory record.265 This process is codified at 10 C.F.R. § 51.102(c), which specifies:

When a hearing is held on the proposed action under the regulations in part 2 of this chapter or when the action can only be taken by the Commissioners acting as a collegial body, the initial decision of the adjudication, it is Intervenors burden to show their significance and materiality. Our boards do not sit to flyspeck environmental documents or to add details or nuances.) (internal quotes omitted).

AEC, 492 hearings, moreover, is not confined to the NRC.273 The rationale for allowing supplementation through the hearing process is straightforwardthe NRCs hearing process allows for greater public participation than NEPA otherwise requires.274

86. The Commission has repeatedly authorized supplementation through the hearing record, most recently last year, when it revised and clarified 10 C.F.R. § 51.102(c).275 The well-established process in Section 51.102(c), which governs the resolution of environmental issues following an adjudicatory hearing, requires the Board to consider the adjudicatory record as a whole when evaluating the environmental impacts of the proposed action, to supplement the FSEIS as necessary, and to modify the NEPA analysis and conclusions, if warranted.276
87. Despite this definitive governing precedent, New York argues that the process of supplementing a final EIS with the hearing record is inconsistent with another regulation, 10 C.F.R. § 51.92, which requires that the Staff prepare a supplemental EIS when there are F.2d 998, 1001-02 (2nd Cir. 1974) (omissions from an FEIS can be cured by subsequent consideration of the issue in an agency hearing); New England Coalition on Nuclear Pollution v.

This procedure fully comports with the letter and spirit of NEPA.) (citing Aberdeen & Rockfish R.R. v. SCRAP, 422 U.S. 289, 320-21 (1975); Citizens For Safe Power, Inc. v.

substantial changes to the proposed action or new and significant information.277 According to New York, this regulation requires an FSEIS supplement to address any new and significant information brought to light during the hearing if that information was not addressed in the FSEIS.278

88. New Yorks argument is incorrect for two reasons. First, despite Section 51.92s longstanding existence, the Commission has repeatedly authorized supplementation through the hearing record, most recently in reaffirming and clarifying 10 C.F.R. § 51.102(c) last year.279 Second, [a] basic tenet of statutory construction, equally applicable to regulatory construction,

[is] that a statute should be construed so that effect is given to all its provisions . . . .280 New Yorks claim that Section 51.92a more general regulation governing all EISs prepared by the NRC Staffforbids the supplementation of an EIS through the hearing record would render meaningless the more specific provisions in Section 51.102(c), which governs the resolution of environmental issues following an adjudicatory hearing. Because New Yorks argument would give no effect to Section 51.102(c), it cannot be correct.281

89. None of the federal cases on which New York relies is relevant to interpreting the NRCs regulations in Part 51, nor do these cases establish that those regulations somehow undermine the NEPA public participation process. The only two arguably pertinent cases cited 277 See, e.g., New York Rebuttal Position Statement at 31 (NYS000419) (NRC Staff may cure its NEPA deficiencies only by supplementing the FSEIS and circulating the supplement for public review and comment.); State of New Yorks Revised Statement of Position Regarding Contention NYS-17B at 7-8 (June 29, 2012) (New York Rebuttal Position Statement for 17B) (NYS000433).

281 Nor does the supplementation of an EIS through the hearing process necessarily mean that there is new and significant information. On the contrary, supplementation of the record through the Section 51.102 process is appropriate when the record of hearing shows no significant new picture of the environmental impacts of the proposed action. See Hydro Res, Inc., CLI-01-04, 53 NRC at 53.

by New York are readily distinguished from the NRCs hearing process by the NRCs Appeal Board decades ago, in decisions that remain binding in this proceeding and thus mandate rejecting New Yorks theory.282

90. First, in the I-291 Why? case, the court invalidated an agency decision because subsequent studieswhich were not circulated for review and comment and were available only to agency officials and not the publicshowed the EIS to be inadequate.283 In ALAB-262, the Limerick Appeal Bound readily distinguished the NRCs public hearing supplementation process from this situation.284 The Appeal Board found significant distinctions between the unpublished supplemental studies that the courts invalidated in I-291 Why? and any supplemental NEPA analysis that may result from the NRCs contested, public adjudicatory proceeding.285 This NRC proceeding is no different, in that the environmental issues have been thoroughly tested through a public, adversarial adjudicatory proceeding.
91. Second, ten years later, the Appeal Board considered the claim that Grazing Fields Farms v. Goldschmidt forbids the amendment of a final environmental statement through the hearing record, but again it found that case to be easily distinguished from the NRC hearing process.286 In Grazing Fields, the First Circuit held that the Federal Highway Administrations reliance on certain studies and memoranda that were in the administrative 282 New Yorks remaining authorities stand for the general principles that NEPA requires public participation in agency decisionmaking and the publication of relevant environmental information. See Minn. Public Interest Research Group v. Butz, 541 F2d 1292 (8th Cir. 1976); Ohio Valley Envtl Coalition v. Hurst, 604 F.Supp.2d 860 (S.D.W.Va. 2009); Custer Cnty. Action Assn v.

Once again, this hearing is no different, in that the relevant environmental issues have been fully and rigorously ventilated through a public adjudicatory hearing.289 Certainly, New York, as a full participant in this proceeding, can claim no prejudice to its own interests.290 ALAB-819 therefore controls, and mandates the rejection of New Yorks argument.
93. In summary, Section 51.102(c), which governs the resolution of environmental issues following an adjudicatory hearing, requires the Board to consider the adjudicatory record as a whole when evaluating the environmental impacts of the proposed action, to supplement the FSEIS as necessary, and to modify the NEPA analysis and conclusions, if warranted.291 287 Grazing Fields Farm v. Goldschmidt, 626 F.2d 1068 (1st Cir. 1980).

288 See Limerick, ALAB-819, 22 NRC at 705-07 & n.33 (citing New England Coalition on Nuclear Pollution v.

NRC, 582 F.2d at 94). The Appeal Board also rejected the argument that certain changes made to Part 51 in 1984 required the recirculation of NEPA documents following a hearing, holding that section 51.102 serves the same purpose as its differently worded predecessor, incorporating the adjudicatory decision into the environmental record of decision. See id. As detailed above, the Commission and its Boards have uniformly followed this interpretation of Section 51.102 ever since.

See NRC Staff Testimony at 2-4 (A1-2) (NRC000041).

299 Due to an internal reallocation of review responsibilities and associated staff resources within the Division of Risk Assessment, the license renewal SAMA reviews were recently reassigned to another branch, the Accident Dose Branch. NRC Staff Testimony at 4 (A2) (NRC000041). However, Mr. Harrison has retained responsibility for those SAMA reviews that were performed under APLA, including the IPEC SAMA analysis review. Id.

companies providing various services to the U.S. Department of Energy and national laboratories. Mr. Harrison also worked as a Research Engineer at the Battelle - Pacific Northwest Laboratory in Richland, Washington.

104. Based on the foregoing, and the respective backgrounds and experience of Dr. Bixler, Dr. Ghosh, Mr. Jones, and Mr. Harrison, the Board finds that all four Staff witnesses are qualified to testify as expert witnesses relative to the issues raised in NYS-12C.

3. New Yorks Expert Witness 105. New York presented testimony from one witness, Dr. Lemay. Dr. Lemay submitted written direct and rebuttal testimony and gave oral testimony at the hearing.

106. Dr. Lemay is Vice President of ISR.300 He holds a Ph.D. in Physics of Nuclear Reactors from the University of Birmingham, United Kingdom and is a professional engineer in the provinces of Ontario and Quebec, Canada. He has twenty-seven years of experience in safety analysis, emergency response plans, procedures and systems, radiation protection, radiation transport, risk assessment, environmental impact assessment, standards and guidelines.

He also has performed or participated in audits and evaluations, emergency exercises, courses and training exercises, and international projects. Dr. Lemay teaches an advanced-level course on the COSYMA and MACCS2 computer codes for health physicists and engineers.

107. Based on the foregoing, and Dr. Lemays background and experience, the Board finds that Dr. Lemay is qualified to testify as an expert witness on issues raised in NYS-12C.

300 Dr. Lemays professional qualifications are provided in his curriculum vitae (NYS000291) and summarized in his testimony. See New York Direct Testimony at 1:21-3:49 (NYS000241).

B. The SAMA Analysis Methodology 108. Before addressing New Yorks specific claims, we discuss the IPEC SAMA analysis methodology, including the MACCS2 inputs challenged by New York.301 As stated above, a SAMA analysis is intended to identify potential changes to a nuclear power plant, or its operations, that could reduce the already-low risk (the likelihood and/or the impact) of a severe accident, for which the benefit of implementing the change outweighs the cost of implementation.302 Changes to the plant that could reduce the risk of a severe accident include hardware modifications or operational changes (e.g., improved procedures and augmented training of control room and plant personnel).303 These potential changes are called SAMAs or SAMA candidates.304 109. A SAMA analysis models numerous accident release conditions that could, based on probabilistic analysis, occur at any time under varying weather conditions during a one-year period to calculate the mean annual consequences of a severe accident for the entire 50-mile radius area of interest.305 As such, a SAMA analysis makes use of best estimate values and 301 The parties prefiled testimony on NYS-12C contains extensive discussions of the SAMA analysis methodology. See Entergy Testimony at 16-46 (A27-A60) (ENT000450); NRC Staff Testimony at 19-31 (A8-A25) (NRC000041); New York Direct Testimony at 10:204-19:511 (NYS000241). Also, during the evidentiary hearing on NYS-12C, the Board requested an overview of the SAMA analysis methodology to lay the groundwork for further questions. The parties witnesses provided that overview on the first hearing day.

involves an averaging of potential consequences.306 The parties experts all agreed on this point.307 110. The industry has developed a guidance document, NEI 05-01, Rev. A (NEI 05-

01) to facilitate the preparation of complete SAMA analyses.308 NEI 05-01 was developed by several SAMA experts, including Ms. Potts, and was issued by NEI in November 2005.309 It identifies the information an applicant should include in a SAMA analysis supporting a license renewal application.310 NEI 05-01 draws from experience gained from prior SAMA analyses and NRC Staff reviews thereof.311 The Staff has specifically endorsed NEI 05-01 and recommended that applicants for license renewal follow the guidance provided in NEI 05-01, Revision A when preparing their SAMA analyses.312 111. A SAMA analysis involves four major sequential steps.313 In brief, the first step of a SAMA evaluation is to identify and characterize the leading contributors to core damage 306 Oct. 17, 2012 Tr. at 1907:3-7 (Teagarden) (A SAMA analysis is designed to be what we say [is] a best estimate analysis, a representative average basis. And to present that average basis you need to look at both ends of the spectrum.).

frequency (CDF) and offsite risk based on a plant-specific risk study.314 The second step in the process is to identify candidate SAMAs to mitigate these risk contributors.315 In the third step, an initial screening is performed to determine which SAMAs cannot be cost-beneficial.316 For example, if the cost of implementing a SAMA is higher than the elimination of all risk from operating the plant (called the maximum attainable benefit), then that SAMA is screened out.317 In the final step, a benefit assessment is performed for each SAMA that survives the initial screening to address how the change would affect relevant risk measures (i.e., the reduction gained in core damage frequency, offsite population dose risk, and offsite economic cost risk).318 An implementation cost assessment also is performed for each SAMA.319 To identify potentially cost-beneficial SAMAs, the net benefit of each SAMA is estimated and compared to its estimated implementation cost.320 112. As described further below, Entergy followed the four-step approach described above in performing both its original April 2007 SAMA analysis and December 2009 revised SAMA analysis (in which it used corrected meteorological data).321 The Staffs detailed review 314 See Oct. 17, 2012 Tr. at 1900:25-1910:2 (Teagarden); Entergy Testimony at 18-19 (A31) (ENT000450); NRC Staff Testimony at 19 (A9), 21 (A12) (NRC000041).

NEI 05-01 also recommends that applicants perform sensitivity analyses that evaluate how changes to certain assumptions and uncertainties in the SAMA analysis would affect the cost-benefit analysis outcome. See Entergy Testimony at 47 (A62) (ENT000450);

NEI 05-01 at 30-32 (NYS000287). As documented in the FSEIS, Entergy performed a number of sensitivity analyses. See FSEIS, Vol. 3, App. G at G-18, G-21, G-40, G-45 to G-47, G-49 (NYS00133I) (discussing Entergys various sensitivity analyses, including cases addressing use of a 3 percent discount rate (instead of 7 of Entergys SAMA analysis is summarized in Section 5.2 of the FSEIS and documented in full in Appendix G of the FSEIS.322

1. Characterization of Plant Risk (Step 1) 113. Three PRA steps are required to perform the first step of a SAMA analysis.323 The Level 1 PRA analyzes initiating events (e.g., equipment failures, operator actions) and ensuing accident sequences leading to core damage, and the results of that analysis are used as inputs to the Level 2 PRA, which evaluates accident progression leading to containment failure (or bypass) and release of radionuclides to the environment.324 The Level 3 PRA combines the Level 2 PRA results (source terms and frequencies) with site-specific parameters (e.g.,

population distribution, meteorological data, land use data, and economic data) to estimate offsite public dose and offsite economic consequences of the postulated releases to the environment.325 114. Entergy quantified the level of risk associated with potential reactor accidents using plant-specific PRAs and other risk models.326 Specifically, Entergy used the most recent probabilistic safety assessments for IP2 and IP3 available at the time it performed the SAMA analysis as well as insights from the Individual Plant Examination (IPE) and the Individual Plant Examination of External Events (IPEEE) for each unit.327 Entergy used the MACCS2 percent), use of a longer plant life, tourism and business losses, and an increased probability of a thermally induced steam generator tube rupture (TI-SGTR)).

code to perform the plant-specific offsite consequence analysis (i.e., the Level 3 PRA portion of the analysis).328 115. The MACCS2 code is the standard tool used in the U.S. to perform the offsite consequence analysis in the Level 3 portion of the PRA.329 MACCS2 performs its calculations based on plant- and site-specific, regional, and industry-standardized regulatory inputs (e.g., dose conversion factors, breathing rates).330 Plant-specific inputs to MACCS2 include, for example, the PRA-based source terms for each source term release category and the reactor core radionuclide inventory, site-specific meteorological data, projected population distribution, and economic data.331 The source term is the amount and radionuclide composition of material postulated to be released from the core of the analyzed nuclear power reactor during an accident scenario.332 116. MACCS2 is divided into three primary modulesATMOS, EARLY, and CHRONC.333 ATMOS performs all calculations pertaining to atmospheric transport, dispersion, and deposition of radioactive material, and to radioactive decay of that material both before and 328 See id. at G-4, G-19 to G-22.

332 NRC Staff Testimony at 23-24 (A17-18) (NRC000041). The information in the source term description includes the quantity of each important radionuclide released into the atmosphere, the initial time of the release relative to the start of the accident, the duration of the release, the elevation of the release, the buoyancy of the plume released, and the particle size of the released material. Source terms generally depend on how rapidly the accident progresses, the path by which the radionuclides escape from the reactor into containment, the path through containment (or possibly bypassing containment altogether), and the effectiveness of both passive and active safety features, especially pools and sprays, that are intended to mitigate releases by, for example, scrubbing the radionuclides and/or reducing containment internal pressure driving the release.

after its release into the atmosphere.334 It calculates air and ground concentrations, plume size, and timing information for all plume segments as a function of downwind distance.335 117. The results of the ATMOS calculations are then used by the other MACCS2 modules.336 Specifically, EARLY uses the calculated air and ground concentrations, plume size, and timing information for all plume segments calculated by ATMOS and other inputs (e.g.,

population) to calculate consequences due to radiation exposure in the emergency phase (i.e., in the first seven days from the time of release in the IPEC SAMA analysis).337 118. CHRONC uses the radioactivity concentrations determined by ATMOS, as well as extensive economic cost data inputs and parameters, to determine long-term offsite population dose and long-term economic costs.338 Long-term consequences are calculated for the period starting after the seven-day emergency phase and extending approximately 30 years.339 119. There are numerous economic cost inputs to CHRONC including, for example, average county-wide value of farm wealth and of non-farm wealth, average cost of labor to perform decontamination, population relocation costs, and daily cost for an evacuated person.340 Consistent with NEI 05-01 guidance, the economic inputs to the SAMA analysis are expressed in dollars for the year in which the SAMA analysis is being performed.341 This enables SAMA 334 Oct. 17, 2012 Tr. at 2057:8-12 (OKula); Entergy Testimony at 28 (A44) (ENT000450); NRC Staff Testimony at 25-26 (A19) (NRC000041).

economic costs to be compared to SAMA mitigation costs in current day dollars.342 To scale available economic data from a past census or survey to current conditions, NEI 05-01 recommends the use of the ratio of the consumer price indices (CPIs).343 120. MACCS2 provides results in terms of offsite population dose and offsite economic cost that are used to compute the offsite risk measures; i.e., population dose risk (PDR) expressed in units of person-rem/year, and offsite economic cost risk (OECR) expressed in dollars/year.344 The individual PDRs and OECRs for the spectrum of different accident release categories are summed to determine the overall PDR and overall OECR for the SAMA analysis.345 The PDR and OECR are the mean annual risk metrics and represent the mean cumulative impacts from postulated severe accidents (i.e., dose or economic costs) to all individuals and land within a 50-mile radius of the plant.346 Entergy calculated mean PDRs of 87.4 person-rem/year and 94.8 person-rem/year for IP2 and IP3, respectively.347 It calculated mean OECRs of 2.12 x 105 dollars/year and 2.61 x 105 dollars/year for IP2 and IP3, respectively.348 342 Entergy Testimony at 45 (A58) (ENT000450).

These mean values (which are obtained from the MACCS2 Level 3 PRA) are multiplied by the estimated frequency of the accident (obtained from the Level 1 and Level 2 PRAs) to determine population dose risk and offsite economic cost risk for each release category studied.

2. Identification of Potential SAMA Candidates (Step 2) 121. Entergy identified possible SAMAs for reducing the risk associated with the major risk contributors for each unit.349 In evaluating potential SAMAs, Entergy followed standard industry guidance and considered SAMAs that addressed the major contributors to the CDF and large early release frequency (LERF) at IP2 and IP3, as well as SAMA candidates for other plants that have submitted license renewal applications.350 Entergy identified 231 candidate SAMAs for IP2 and 237 SAMAs for IP3 (i.e., Phase I SAMAs).351 It then performed an initial screening in which it removed Phase I SAMAs that (1) were not applicable to IP2 and IP3 for design-related reasons, (2) were already implemented at IPEC, or (3) could be combined with other, similar SAMA candidates.352 This screening process reduced the list of potential SAMAs to 68 for IP2 and 62 for IP3 (i.e., Phase II SAMAs).353
3. Quantification of Risk Reduction Potential and Implementation Cost (Step 3) 122. Entergy next performed more detailed evaluations of the Phase II SAMAs.

Specifically, it evaluated each Phase II SAMAs benefit by modifying the baseline PRA to account for the effect of the plant improvement being evaluated, and then compared the risk results of the baseline and modified PRAs.354 The baseline PRA for a plant evaluates the risk of operating the plant based on its current state; i.e., without implementing any of the proposed improvements or procedures.355 For comparison purposes, all calculated consequences were 349 FSEIS, Vol. 3, App. G at G-30 to G-33 (NYS00133I).

expressed in dollars.356 The economic risk (in dollars) is reevaluated, assuming that one of the SAMAs was implemented.357 The benefit is the reduction in economic risk (in dollars) after implementing the SAMA compared with the baseline.358 123. Entergy evaluated each Phase II SAMA candidate individually.359 It performed a benefit assessment to address how the mitigation measure would affect relevant risk measures (i.e., CDF, PDR, and OECR).360 Entergy also developed cost estimates for implementing each SAMA candidate.361 This process included reviewing cost estimates for similar improvements considered in prior NRC-approved SAMA analyses.362

4. Identification of Potentially Cost-Beneficial SAMAs (Step 4) 124. Finally, Entergy compared the costs and benefits of each of the remaining SAMAs to determine whether the SAMA was cost-beneficial.363 To account for uncertainties 356 Id. at 22 (A13).

359 Id. In reality, if a given SAMA were to be implemented at the plant, then the baseline risk would decrease, such that incremental benefit of implementing additional SAMAs would decrease, particularly when the additional SAMAs are acting on the same accident sequences. See Oct. 18, 2012 Tr. at 2165:21-25, 2342:9-21 (Ghosh); see also id. at 2343:8-12 (Ghosh) (So there are essentially diminishing returns. As you -- if you were to do it in a sequential manner, you have increasing diminishing returns for implementing subsequent SAMA candidates.).

360 NRC Staff Testimony at 19 (A9), 22 (A13) (NRC000041). The benefit calculated for an individual SAMA is a fraction of the maximum attainable benefit, because an individual SAMA will not eliminate all possible accident initiators or mitigate all kinds of possible accidents. Id. at 22 (A13). Further, a given SAMA candidate does not necessarily have the same effect across all release categories (id.); i.e., the impact depends on the risk significance of the specific system that is being influenced in the PRA model. Id. at 19 (A9), 21-22 (A13) (NRC000041); Oct. 17, 2012 Tr. at 1912:19-1913:14 (Teagarden). For example, the effect of the plant improvement might be to decrease the likelihood of an accident or group of accidents calculated in the Level 1 PRA. Other plant improvements might have no effect on accident frequencies, but might diminish the outcome of some of the accidents, leading to smaller consequences. These would affect the magnitude of the source term predicted in the Level 2 PRA and result in lower consequences in the Level 3 PRA. Some plant improvements would reduce both accident frequencies and consequences; i.e., they would be both preventers and mitigators. Oct. 17, 2012 Tr. at 1915:17-1916:10 (OKula).

associated with the internal events CDF calculations, Entergy also compared the cost of SAMA implementation with a benefit value estimated by applying an uncertainty multiplier to the internal and external events estimated benefit.364 This value is defined as the baseline benefit with uncertainty.365 Entergy included any additional SAMAs identified as potentially cost-beneficial in the uncertainty analysis within the set of potentially cost-beneficial SAMAs.366 As documented in the FSEIS, Entergy identified a total of 22 IP2 and IP3 SAMA candidates as potentially cost-beneficial to implement in its final, revised SAMA analysis.367 C. Summary of Contested MACCS2 Input Values 125. As discussed above, Entergy used MACCS2 to provide plant-specific offsite consequence information as part of the first step in the SAMA analysis. Entergy thus used numerous site-specific inputs, such as IPEC-specific meteorological data (year 2000 data from the IPEC meteorological tower), the projected year 2035 population distribution within the 50-mile SAMA analysis region (based on year 2000 census data and state and county-level population projections), the IP2 and IP3 core radionuclide inventories, IP2 and IP3 source term and release characteristics, and region-specific economic data (i.e., for value of farm and nonfarm wealth).368 Consistent with NEI 05-01 guidance and prior SAMA analyses, Entergy also used certain standardized values as inputs to the MACCS2 code.

126. With the exception of Entergys 2035 population projection and the VALWNF region-specific economic discussed below (see infra Section IV.I.1), New York did not 364 FSEIS, Vol. 3, App G. at G-36 to G-38 (Tbl. G-6), G-42, G-45 (NYS00133I).

For purposes of this assessment, Entergy applied a multiplier of 8 to the internal-event benefits for each unit to account for both internal and external events, with analysis uncertainty. The multiplier of 8 slightly exceeds the product of the external-event multiplier and the uncertainty factor for each unit (i.e., 3.80 x 2.10=7.98 for IP2, and 5.53 x 1.40=7.73 for IP3) and adds some additional conservatism.

challenge Entergys numerous site-specific MACCS2 inputs.369 It principally took exception with Entergys use of several standardized decontamination cost-related inputs that are derived from NUREG-1150 and used in MACCS2 Users Guide Sample Problem A (see Table 1 below).370 127. As set forth in Dr. Lemays prefiled testimony and the ISR Report, New York proposed alternative values for the following IPEC-specific and standardized MACCS2 inputs:

  • CDNFRM, which defines the nonfarmland decontamination cost per individual for each level of decontamination. This input value was derived from NUREG-1150.
  • TIMDEC, which defines the time required for completion of each of the decontamination levels. This input value was derived from NUREG-1150.
  • VALWNF, which defines the value of the per capita nonfarm wealth in the region.

Nonfarm wealth includes all public and private property not associated with farming that would be unusable if the region was rendered either temporarily or permanently uninhabitable (e.g., the cost of land, buildings, infrastructure, and non-recoverable equipment or machinery). This input value was developed using economic data specific to the IPEC region.

  • POPCST, which defines the per capita removal cost for temporary or permanent relocation of population and businesses in a region rendered uninhabitable during the long-term phase time period. This cost is assessed if any of the following actions are required: decontamination alone, decontamination followed by interdiction, or condemnation. This value is derived in a way that takes account of both personal and corporate income losses for a transitional period as well as moving expenses. This input value was derived from NUREG-1150.
  • DSRATE, which defines the expected rate of return from land, buildings, equipment, etc. (e.g., the inflation-adjusted real mortgage rate for land and buildings could be used). This input value was derived from NUREG-1150.

369 The details associated with Entergys 2035 population estimate, which New York challenged in a separate contention, NYS-16B, are presented in Entergys expert witness testimony on that contention. See Testimony of Entergy Witnesses Lori Potts, Kevin OKula, Grant Teagarden, and Jerry Riggs on Consolidated Contention NYS-16B (Severe Accident Mitigation Alternatives Analysis) (Mar. 28, 2012) (ENT000003).

  • FRNFIM, which defines the nonfarm wealth improvements fraction. This input value was derived from NUREG-1150.371 128. In the IPEC SAMA analysis, Entergy used two CDNFRM values (as well as two TIMDEC values), one corresponding to a dose reduction factor (DRF) of 3 and the other corresponding to a DRF of 15.372 As Dr. OKula and Mr. Teagarden explained, in MACCS2, the relevant code input parameter is DSRFCT, which is defined as the effectiveness of the various decontamination levels in reducing dose.373 129. Table 1 below shows Entergys input parameter values, along with the corresponding values from NUREG-1150, for the six CHRONC parameters for which New York proposed alternative values. It also shows New Yorks proposed alternative values, as developed by Dr. Lemay and later revised in his June 2012 prefiled rebuttal testimony in response to Entergy and NRC Staff criticisms of his methodologies.374 371 See Entergy Testimony at 42 (A54, Tbl. 1), 65 (A84) (identifying and defining CHRONC parameter inputs for which Dr. Lemay proposed alternative values).

373 Id. at 66 (A86) (quoting NUREG/CR-6613, Vol. 1 at 7-11 (ENT000243)). The inputs applied in the MACCS2 code to evaluate decontamination, countermeasures such as interdiction, and economic consequences are termed dose reduction factors, or DRFs, rather than decontamination factors and are represented by the code parameter DSRFCT. Id. (citing NUREG/CR-6613, Vol. 1 at 7-9 to 7-11 (ENT000243)). A similar term, decontamination factor (DF), generally is defined as the ratio between the contamination levels before and after decontamination has been performed. Id. at 65 (A85). Thus, the DF is a measure of the efficiency of removing radioactivity from a surface, whereas the DRF generally refers to the reduction in dose levels following an application of a countermeasure. Id. at 66 (A86); see also Oct. 18, 2012 Tr. at 2295:15-2296:12, 2296:16-2297:4 (Teagarden). As a matter of convenience, we use the term decontamination factor or DF below.

130. The Board discusses each of these input parameters below. However, as at the hearing, we focus primarily on the CDNFRM and TIMDEC values (as reflected in Approaches A-D in the ISR Report), given the parties agreement that these values have the most significant impact of the MACCS2 parameters at issue here.375 Indeed, during the hearing, Dr. Lemay stated: It was our assessment that CDNFRM and TIMDEC were the most important ones, and the rest had minimal impact on the calculation of the offsite economic cost.376 131. Thus, at its core, Contention NYS-12C relates to the reasonableness of the CDNFRM and TIMDEC values used as inputs to MACCS2 in the IPEC SAMA analysis. In the Boards view, New Yorks position devolves into three primary claims. New York and its expert, Dr. Lemay, allege that: (1) Entergys and the NRC Staffs use of NUREG-1150 inputs (which, as discussed below, also are used in MACCS2 Users Guide Sample Problem A) in lieu of site-specific inputs is inappropriate because the challenged inputs were developed decades ago and are not appropriate for the dense population and buildings surrounding IPEC;377 (2) the nonfarm decontamination cost values used in the SAMA analysis are also not rationally related to the area surrounding IPEC;378 and (3) the decontamination factors and decontamination time values used in the SAMA analysis are not rationally related to the area surrounding IPEC.379 132. Accordingly, the balance of our decision is framed principally by the three issues set forth above. In addressing these issues, we are guided by the Commissions recent SAMA-related jurisprudence. In particular, we consider (1) whether the alleged deficiencies in 375 See Oct. 17, 2012 Tr. at 2053:18-2055:8 (Teagarden, Lemay).

376 Id. at 2054:23-2055:1 (Lemay) (emphasis added); id. at 2055:1-4 (So if youre limited by time and you want to get to the crux of the matter, CDNFRM and TIMDEC are the two parameters that are really at play here.)

Entergys SAMA analysis inputs are valid and so significant that they render the SAMA analysis altogether unreasonable under NEPA standards;380 and (2) whether the alleged deficiencies plausibly could alter NRC Staffs conclusions as to which SAMAs are cost-beneficial.381 D. Entergys Use of Economic Cost Inputs From NUREG-1150/MACCS2 Sample Problem A is Reasonable Under NEPA Standards 133. The Board first considers New Yorks claim that Entergy and the NRC Staff arbitrarily relied on default input values derived from MACCS2 Sample Problem A (as taken from NUREG-1150).382 New York claimed that these values are inappropriate because they are not specific to the area surrounding IPEC, including the hyper-urban New York City with its very high population density and high-rise buildings.383 In particular, Dr. Lemay asserted that the MACCS2 Sample Problem A inputs used by Entergy are based on data that are specific to the Surry nuclear power plant in Virginia, which he claimed is largely surrounded by farmland.384 New York also argued that the IPEC SAMA analysis inputs do not properly account for the size of particles released by a nuclear power reactor severe accident.385 134. Accordingly, in this portion of our decision, we discuss (1) the origin and purpose of the MACCS2 Sample Problem A values cited by New York (including their relationship to the Surry site); (2) Entergys justification for using values derived from NUREG-1150/MACCS2 Sample Problem A; (3) and New Yorks concern about the size of radionuclide particles that are 380 Pilgrim, CLI-12-01, slip op. at 25.

released to the atmosphere (i.e., postulated severe accident source terms) determined from the IPEC Level 2 PRAs.

1. Entergy reasonably relied on Sample Problem A input values insofar as those values are based on, and coincide with, the relevant values in NUREG-1150 135. By way of background, Dr. OKula and Mr. Teagarden explained the purpose of Sample Problem A and its relationship to the IPEC SAMA analysis.386 Specifically, they explained that Section 4.0 of the MACCS2 Users Guide (NUREG/CR-6613) contains six sample problems, Sample Problems A through F.387 The MACCS2 Users Guide uses these sample problems to compare MACCS and MACCS2 (e.g., the dose algorithms) and to show different aspects of code functionality.388 They also noted that Sample Problem A provides one of the more complete sample problems,389 and offers a full exercise of the code in all of its modules.390 136. The MACCS2 Users Guide states that Sample Problem A is based on input data obtained from NUREG-1150.391 NUREG-1150 is a seminal PRA study that presented population dose results for a 50-mile radial region around each of five representative nuclear power plants (including Surry Unit 1), as well as population dose results for a broader region (i.e., greater than 50 miles) that is typically referred to as the entire region.392 137. The NUREG-1150 study used the MACCS code (MACCS2s predecessor) and applied the same CHRONC economic inputs for each of the five study sites, except for the variables related to farm and nonfarm wealth (VALWF and VALWNF), which are based on 386 See Entergy Testimony at 59 (A75), 60-61 (A77) (ENT000450).

region-specific inputs.393 NUREG-1150 thus applied the same CDNFRM and TIMDEC values used in Sample Problem A to all five of the NUREG-1150 study sites.394 Therefore, contrary to New Yorks claim, the NUREG-1150 authors did not view those values as being applicable only to the Surry site.395 And, as discussed further below, use of the NUREG-1150 CDNFRM values is reasonable under NEPA because in SAMA analysis, the values are multiplied by region-specific population densities.

138. Entergy relied on certain Sample Problem A values insofar as those values are based on, and coincide with, the relevant values in NUREG-1150.396 Specifically, Entergy applied inputs that were based on the NUREG-1150 study, and it updated those input values using the CPI ratio for 1986 to 2005 (the basis year for the IPEC SAMA analysis), consistent with NEI 05-01 guidance.397 Mr. Teagarden emphasized that Entergy did not rely on Surry land use information, but instead used site-specific, regional-specific economic data for the value of land and property.398 139.

SAMA analyses) performed in the U.S.399 They further stated that, to their knowledge, all prior NRC license renewal applicants have used these same values (as appropriately escalated) in their SAMA analyses.400 140. In summary, the Board disagrees with New York that the Sample Problem A values are inapplicable default values originally developed for the Surry site. As Entergys witnesses explained, the contested Sample Problem A values are derived from the NUREG-1150 study, which applied them to all five plants examined in that study. The Board finds that the challenged values (including the NUREG-1150 values for CDNFRM and TIMDEC) are consistently used in license renewal SAMA analyses and are appropriate for that purpose.

2. Entergy and the NRC Staff appropriately considered the applicability of NUREG-1150 input values to the IPEC site-specific SAMA analysis 141. Ms. Potts, who helped prepare the IPEC SAMA analysis, testified that she and other Entergy technical reviewers considered the applicability of the NUREG-1150 values (as escalated) and concluded that they are reasonable values for IPEC.401 She noted that Entergy described the bases for this conclusion in its February 2008 RAI Response.402 That response addressed the Staffs request that Entergy describe the key MACCS2 input parameters that contribute to the offsite economic cost risk, and justify the applicability of Entergys selected input values to the IPEC site and region.403 The February 2008 RAI Response states that the 399 Id. at 61 (A78) (ENT000450).

NUREG-1150 values, as adjusted to 2005 dollars using the CPI ratio method, are reasonable for the IPEC region for three principal reasons that the Board and parties discussed at hearing.404 142. First, the NUREG-1150 economic and decontamination-related values are viewed as the most reasonable values currently available based on industry-reviewed studies.405 Dr. OKula and Mr. Teagarden testified that standard MACCS2 modeling for NRC assessments uses NUREG-1150 input values due to their well-established pedigree within the PRA community.406 Dr. OKula emphasized that NUREG-1150 was made available for public comment and subjected to multiple peer reviews that involved an unprecedented level of technical scrutiny.407 143. Dr. OKula and Mr. Teagarden stated that NRC and industry technical staff vetted key economic inputs before their inclusion in NUREG-1150, as reflected in NUREG/CR-4551:408 Estimation of offsite accident consequences is the customary final step in a probabilistic assessment of the risks of severe nuclear reactor accidents. Recently, the Nuclear Regulatory Commission reassessed the risks of severe accidents at five U.S. Power reactors (NUREG-1150). Offsite accident consequences for NUREG-1150 source terms were estimated using the MELCOR Accident Consequence Code 404 See February 2008 RAI Response, Attach. 1 at 38 (ENT000460).

System (MACCS). Before these calculations were performed, most MACCS input parameters were reviewed, and for each parameter reviewed, a best-estimate value was recommended. This report presents the results of these reviews. Specifically, recommended values and the basis for their selection are presented for MACCS atmospheric and biospheric transport, emergency response, food pathway, and economic input parameters.409 144. Entergys experts further testified that there is no NRC- and industry-accepted alternative to the NUREG-1150 values, and that to their knowledge, all license renewal applicants have used these NUREG-1150 values (as escalated) in their SAMA analyses.410 Mr. Teagarden explicitly stated that we believe these values represent the best values that are available for a SAMA analysis. We know of no technically superior values to use for the MACCS code input for these [parameters].411 Dr. OKula and Mr. Teagarden also cited the NRCs use of the NUREG-1150 values in the recently-completed SOARCA project as further evidence of their continued applicability and suitability for use in SAMA analyses.412 145. Second, as stated in Entergys February 2008 RAI Response, the NUREG-1150 economic cost parameters were developed based on information obtained for the five plant regions studied by the NRC in NUREG-1150413 and are reasonable for the Indian Point region because the initial development included heavily populated regions.414 Mr. Jones elaborated on this point at the hearing, stating that two of the five sites studied in NUREG-150 are not unlike IPEC with respect to the population density within the 10-mile radius Emergency 409 NUREG/CR-4551, Vol. 2, Rev. 1, Part 7 at iii/iv (NYS000248) (emphasis added).

Planning Zone (EPZ).415 He stated that the IPEC EPZ has about 300,000 people,416 and that the Surry EPZ (which includes the northern and eastern side of the James River) has a very comparable population density.417 He also noted that the now-decommissioned Zion plant located just north of Chicago had an EPZ population density comparable to that of IPEC.418 146. Third, as stated in Entergys February 2008 RAI Response, the NUREG-1150 decontamination cost values are reasonable for the IPEC region because they are based upon levels of contamination and population rather than upon the region in which the contamination occurs.419 In other words, MACCS2 applies the nonfarm economic inputs, including the nonfarm decontamination cost (i.e., CDNFRM), on a per person basis.420 This approach thus accounts for areas with high population densities and low population densities (e.g., due to the high proportions parkland and other rural property) within the 50-mile IPEC SAMA analysis region.421 147. Accordingly, in MACCS2, the populations within the IPEC SAMA analysis region are multiplied by these per person decontamination cost values, as appropriate, making 415 Oct. 17, 2012 Tr. at 1968:11-24 (Jones).

the resulting decontamination cost estimate site-specific.422 For the IPEC SAMA analysis, Entergy developed a year 2035 population estimate based on census data and population projections that are specific to the IPEC SAMA analysis region.423 Therefore, the large population centers (including the New York City metropolitan area) within the SAMA analysis region were multiplied by the CDNFRM values.424 As Mr. Jones and Dr. Bixler stated: By using a per-person basis, this approach takes into account the site-specific high population density of New York City and the correspondingly high density of buildings.425 Dr. Lemay agreed that the application of decontamination costs on a per person basis, as is done in MACCS2, is a valid approach.426 148. In summary, the Board finds that applying appropriately-escalated NUREG-1150 (and hence MACCS2 Sample Problem A) economic and decontamination cost values on a per-person basisas was done in the IPEC SAMA analysisis a reasonable method under NEPA standards. Contrary to New Yorks claim, Entergy and the NRC Staff have fully justified their reliance on the NUREG-1150 economic and decontamination inputs. It is clear that those values have a long-established technical basis and continue to be used in state-of-the-art severe accident consequence analyses, including other SAMA analyses and the recent SOARCA project.427 422 See Oct. 17, 2012 Tr. at 1949:23-1950:8 (Teagarden); Entergy Testimony at 55-58 (A72) (ENT000450). For example, when Entergys CDNFRM value of $13,824 per person (for a DF of 15) is applied to an apartment building housing 200 people, the resulting decontamination cost would $2.7 million.

3. Entergys MACCS2 inputs appropriately account for the types of particles released during a postulated severe accident 149. New York also contended that Entergys MACCS2 decontamination parameter inputs, as derived from NUREG-1150, reflect a faulty assumption that large radionuclide particles would be released by a severe reactor accident,428 and that accounting for smaller particle sizes that would actually be released in such an accident would increase offsite decontamination costs.429 With respect to this issue, Dr. Lemay asserted that small-sized, soluble cesium is more difficult to remove from porous surfaces than the large-sized, insoluble radionuclides, such as plutonium.430 150. As a threshold matter, the basis for New Yorks arguments related to particle size is unclear, given that the NUREG-1150/MACCS2 Sample Problem A values challenged by New York do not specify a particle size.431 Rather, the MACCS2 code user must specify a deposition velocity (a parameter not challenged by New York in NYS-12C).432 As explained by Dr. Bixler, the deposition velocity and surface roughness inputs to the MACCS2 code can be used in tandem to estimate the particle size considered in the SAMA analysis.433 151. Dr. Bixler reviewed Entergys deposition velocity and surface roughness inputs to the MACCS2 code.434 Based on the analysis described in his prefiled testimonywhich Dr. Lemay did not disputehe determined that the IPEC SAMA analysis effectively assumed 428 See New York Position Statement at 4-9, 36-37 (NYS000240) (summarizing contentions NYS-12, 12A, 12B, and 12C and asserting that the FSEIS underestimate[s] the costs associated with the dispersion of small particle radiation from a nuclear power facility accident). Although New York and Dr. Lemay raised this issue in their filings, it was not the subject of significant discussion during the two-day evidentiary hearing.

the release of radionuclide particles having an aerodynamic diameter of 6 micrometers or microns (which corresponds to a physical diameter of 3 micrometers and about a specific density of 4).435 Dr. Bixler stated that this particle size is representative of the aerosols that would be released into the atmosphere during a severe reactor accident.436 As he further noted, this conclusion refutes New Yorks claim that Entergys MACCS2 decontamination cost estimates are based on large-sized radionuclide particles, which New York itself defined as particles ranging in size from tens to hundreds of microns.437 152. Furthermore, Mr. Jones explained that decontamination of small particles is not necessarily more difficult or more costly than for large particles,438 and that there is no evidence that decontamination costs depend on particle sizes when they are in the range of 1 to 10 micrometers.439 He stated that particle size is only one of many factors affecting decontamination cost,440 an observation with which Entergys experts agreed and Dr. Lemay did not dispute.441 435 See id.

436 Id. at 57 (A49). Dr. Bixler stated that Entergys assumed deposition velocity (1 cm/s) is conservative because it produces more deposition and thus requires more decontamination within the 50-mile SAMA analysis region. Id. at 49 (A41), 50 (A43).

New Yorks definition of large radioactive particles is based on the Site Restoration Report. See New York Petition at 143 (citing Site Restoration Report at 2-9 to 2-10, 5-7 (NYS000249)). Notably, in the Seabrook proceeding, the Commission rejected another intervenors reliance on the Site Restoration Report in overruling the admission of a SAMA contention similar to NYS-12C. The Commission stated that the Site Restoration Report is focused on plutonium dispersal events and contains no suggestion that the MACCS2 code assumes inapplicable radionuclide particle sizes.

153. Based on the above findings, the Board concludes that there is no evidentiary support for New Yorks claim that the IPEC SAMA analysis, whether through its use of NUREG-1150 values or other inputs to the MACCS2 code, considers inapplicable radionuclide particle sizes.

E. The CDNFRM Values Used As Inputs to the IPEC SAMA Analysis Have an Established Technical Basis and Are Rationally Related to the IPEC Site 154. As stated above, New York and Dr. Lemay focused heavily on Entergys CDNFRM values. They claimed that support for the NUREG-1150 values simply does not exist,442 and that the values are not rationally related to the IPEC site.443 155. In support of these claims, Dr. Lemay asserted that neither NUREG-1150 nor NUREG/CR-4551 provides a detailed explanation of decontamination costs.444 He further contended that another document cited by the NRC Staff and Entergy in support of the NUREG-1150 CDNFRM values, NUREG/CR-3673, Economic Risks of Nuclear Power Reactor Accidents (Apr. 1984) (NUREG/CR-3673) (ENT000466), is not a reliable source.445 156. As Dr. OKula and Mr. Teagarden testified, Entergy selected values of

$5,184/person and $13,824/person for dose reduction factors (DRFs) of 3 and 15, respectively.446 Entergy obtained these values by using the values from NUREG-1150, which were $3,000/person for DRF of 3 and $8,000/person for DRF of 15, and then adjusting them by the CPI method in accordance with NEI 05-01 (NYS000287).447 The NUREG-1150 CDNFRM 442 New York Rebuttal Position Statement at 10 (NYS000419).

values can be traced to NUREG/CR-3673 (also referred to as Burke).448 NUREG/CR-3673 states that it developed and employed improved models to estimate the economic risks from unanticipated events which occur during U.S. LWR operation.449 As part of this effort, the study estimated the offsite costs of post-accident population protective measures and public health impacts for severe LWR accidents that result in a release of radioactive material to the environment.450 Those costs include non-farm area decontamination costs for three decontamination factors (DF = 3, 15, and 20). NUREG/CR-3673 states that [t]he cost estimates used in this study for various levels of decontamination effort in an area are taken from a detailed review of decontamination effectiveness and costs performed at Sandia National Laboratories (SNL).451 The detailed review apparently was documented in an unpublished report by Robert Ostmeyer and Gene Runkle entitled An Assessment of Decontamination Costs and Effectiveness for Accident Radiological Releases (Ostmeyer report).452 Despite their best efforts, none of the parties or their experts could locate a copy of the report, even in the Sandia library.453 448 See id. at 57 (A72) (ENT000450). See also NUREG/CR-4691, MELCOR Accident Consequence Code System (MACCS) Model Description, Vol. 2 at 1-9, 4-1 (NYS000288) (The economic effect models in MACCS are intended to estimate the offsite costs resulting from a reactor accident.

157. Dr. Lemay contended that the unavailability of the Ostmeyer report renders NUREG/CR-3673 unreliable and leaves a gaping hole in the record.454 Given the apparent link between the NUREG-1150 non-farm decontamination cost values and the Ostmeyer report (via NUREG/CR-3673), the Board does not disagree that the unavailable document might have proven helpful. However, the Board does not find that the documents unavailability renders the NRC Staffs or Entergys reliance on the NUREG-1150 decontamination cost values altogether unreasonable under NEPA.455 As Dr. Ghosh observed, the NUREG/CR-3673 authors presumably had access to the Ostmeyer report when they prepared NUREG/CR-3673.456 Therefore, we can reasonably presume that they reviewed the Ostmeyer reports contents in preparing NUREG/CR-3673, which was published as a final, NRC-approved document.

Moreover, NUREG/CR-3673 expressly states that Dr. Robert Ostmeyer, co-author of the referenced report, provided technical assistance and advice during the preparation of NUREG/CR-3673.457 Thus, we do not agree with New York that NUREG/CR-3673 is an unreliable source.458 158. As discussed above, the NUREG-1150 CDNFRM values have long been used in severe accident consequence analysesincluding all SAMA analyses performed to date.459 The PRA community continues to view them as acceptable values.460 In the Boards view, the 454 New York Rebuttal Testimony at 24:12-17 (NYS000420); New York Rebuttal Position Statement at 10 (NYS000419); Oct. 17, 2012 Tr. at 2043:5-10 (Lemay).

unavailability of the Ostmeyer report does not negate over two decades of established regulatory and probabilistic risk assessment practice. Consistent with NEPAs rule of reason, the NRC Staff has acted based on the best available information and analysis in completing its SAMA evaluation.461 NEPA does not require agencies to resolve all uncertainties, including, in this case, uncertainties associated with the ultimate provenance of the time-tested NUREG-1150 values used in the IPEC SAMA analysis.462 159. In any event, we find that NUREG/CR-3673 contains useful insights into the nonfarm decontamination cost estimates included in NUREG-1150 (as CDNFRM values of

$3,000 and $8,000 per person for DF =3 and DF =15, respectively). NUREG/CR-3673 states that these nonfarm decontamination cost estimates and decontamination factors reflect consideration of different decontamination methods, land uses, and accident magnitudes.

The cost estimates used in this study for various levels of decontamination effort in an area are taken from a detailed review of decontamination effectiveness and costs performed at Sandia National Laboratories (SNL). Cleanup cost estimates were provided for farmland and residential, business, and public property based on decontamination techniques which are currently feasible. The study also considered the large areas which may require decontamination after the worst accidents in defining the variety of decontamination techniques which could be employed.

The non-farm area decontamination costs and effectiveness values used in the new economic model are shown in Table 4.4. The decontamination cost estimates incorporate information on a multitude of possible methods to be used in the decontamination of non-farm areas, and have been weighted to account for residential, commercial and industrial, and public use land areas based on national average statistics. The methods to be employed for each level of effort and each type of area include combinations of decontamination techniques.463 461 Baltimore Gas & Elec. Co., 462 U.S. at 102.

160. Consistent with the above statements, Mr. Teagarden testified that the CDNFRM values ultimately incorporated into NUREG-1150 reflect a mixture of land uses.464 He also noted that the NUREG-1150 nonfarm decontamination cost value was applied universally across the five different sites examined in that study, suggesting that in the developers minds, those values were sufficiently applicable to each of the sites.465 Mr. Teagarden also asserted that the CDNFRM value was intended to be a global value given that the NUREG-1150 study, like a SAMA analysis, examined regions encompassing approximately 7,800 square miles and multiple land uses.466 161. During the hearing, Dr. Lemay pointed to a passage in NUREG/CR-3673 stating that [t]he cost and effectiveness estimates for decontamination contain large uncertainties, and results of future experimentation with decontamination techniques should be used to update models for decontamination.467 However, as Mr. Harrison testified in response, NUREG/CR-3673 also recognizes that the use of standardized decontamination cost values is reasonable when evaluating the potential decontamination costs for non-farm areas impacted by a postulated severe accident, as is done in a SAMA analysis, especially given the uncertainties inherent in such estimates.468 NUREG/CR-3673 states that detailed decontamination cost estimates based on land usage mapping or specific area types is not justified for risk models because areas requiring decontamination are large enough that average values provide reasonable cost estimates.469 It also notes that the large uncertainties inherent in estimates of reactor accident 464 Oct. 18, 2012 Tr. at 2169:24-2170:9 (Teagarden); see also id. at 2142:2-9 (Teagarden).

radionuclide release processes (e.g., source terms), atmospheric transport and deposition, decontamination effectiveness, and decontamination costs limit the usefulness of more detailed analyses.470 The upshot, as the Board sees it, is that more detailed or localized decontamination cost estimates (even assuming they could be developed) are not necessarily better suited for use in a time-averaged and spatially-averaged SAMA analysis.

162. Given the unavailability of the referenced Ostmeyer report, the Board queried whether the decontamination cost estimates presented in NUREG/CR-3673 (and later in NUREG-1150) might be based on a non-reactor (e.g., plutonium) source term, as suggested in New Yorks contention.471 Mr. Jones and Dr. Ghosh testified that they had no reason to believe that NUREG/CR-3673 authors had considered anything other than nuclear power plant severe accident source terms in their report.472 Dr. OKula also stated his expert opinion that NUREG/CR-3673 is concerned with decontamination costs for a reactor-type source term, as evidenced by the documents explicit focus on providing cost figures that implicitly include contamination over broad areas, such as would be expected with those associated with a reactor-type source term.473 163. The NUREG-1150 decontamination values clearly have withstood the test of time, as evidenced by their use in the NRCs recently-completed SOARCA project, a state-of-the-art assessment of the accident progression, radiological releases, and offsite consequences associated with a severe accident.474 NUREG-1935, which discusses the SOARCA project methodology and result, expressly states that [v]alues from NUREG-1150 provide the basis for 470 Id.

decontamination parameters, which consist of two levels of decontamination, just as in NUREG-1150.475 164. It bears emphasis that three of the experts testifying in this proceeding Dr. Bixler, Mr. Jones, and Dr. OKulawere directly involved in the SOARCA project and, in their expert opinions, the NUREG-1150 values are broadly accepted by the PRA community and reasonable for use in a SAMA analysis.476 It is well established that under NEPA, an agency must have discretion to rely on the reasonable opinions of its own qualified experts.477 Therefore, for purposes of its NEPA-based inquiry, the Board gives significant weight to the fact that the NRC currently relies on the same NUREG-1150 values for its state-of-the-art severe accident analyses.478 There also is no evidence in the record that the NRC Staff or the Commission expects licensees to rely on values other than those in NUREG-1150. There is certainly no evidence that the NRC expects licensees to engage in an extensive, world-wide research project to find alternate MACCS2 input values not previously reviewed or approved by 475 Draft NUREG-1935, at 63 (ENT000455) (emphasis added). We note that the final version of NUREG-1935 was published in November 2012, after the hearing on NYS-12C was held.

As Dr. Ghosh explained at the hearing and in a September 28, 2012 affidavit, the referenced e-mail related to a research proposal submitted by a now-deceased NRC Staff member in late 2010 as part of the NRCs FY 13 Long-Term Research Program (LTRP).

the NRC.479 Nor is such action required under NEPA. In fact, it is not at all clear that the NRC would even accept such alternate values for the purposes of a license renewal SAMA analysis given the long-established pedigree of the NUREG-1150 values.

165. Before discussing Dr. Lemays proposed CDNFRM values, we address two more arguments related to Entergys use of values derived from NUREG-1150. First, Dr. Lemay cited two NRC responses to public comments on a draft version of NUREG-1150 as purported evidence that the NUREG-1150 authors expected NRC Staff to require site-specific assessments of the costs of decontamination in the context of specific regulatory activities, such as those currently being conducted at [IPEC].480 Dr. Lemay claimed that the NRCs comment responses do not justify the use of the Sample Problem A inputs at [IPEC] or any other particular reactor.481 166. The Board is not persuaded by Dr. Lemays argument. As Dr. OKula explained during the hearing, the first NRC public comment response cited by Dr. Lemay relates to the first (February 1987) draft of NUREG-1150.482 And, in stating that the 1987 draft does not assess the costs of these or other improvements, the NRC was referring specifically to potential benefits of accident management strategies in reducing core damage frequency;483 viz., the effects of plant operational procedures to provide water and cooling to a reactor core to prevent 479 See Pilgrim, CLI-10-11, 71 NRC at 315-16 (There is no NEPA requirement to use the best scientific methodology, and NEPA should be construed in the light of reason if it is not to demand virtually infinite study and resources.

damage.484 The comment response, therefore, does not speak to the adequacy of the NUREG-1150 economic or decontamination cost values or their applicability to a site-specific SAMA analysis.485 167. The second comment response quoted by Dr. Lemay indicates that the first draft of NUREG-1150 followed conventional NRC methods for cost and benefit analyses, and that those analyses were not included in the second draft (and, subsequently, the final) NUREG-1150 report, because cost/benefit analyses of that type are more properly conducted in the context of specific regulatory activities (such as proposed rule changes).486 So again, the comment response does not relate to the final NUREG-1150 report or to the CDNFRM values incorporated therein.

168. In its rebuttal filings, New York also argued that Entergys reliance on the NUREG-1150 CDNFRM values is unreasonable because a site-specific analysis of decontamination costs is eminently possible and had been completed in conjunction with

[Draft] NUREG/CR-5148.487 Dr. Lemay stated that in further reviewing NUREG-1150, he learned that, in the 1980s, the NRC Staff contracted with Battelle Pacific Northwest Laboratory (PNL)488 to conduct a case study of the economic costs associated with severe accidents at

[Indian Point].489 According to Dr. Lemay, this site-specific case study is described in Chapter 5 of Draft NUREG/CR-5148.490 Dr. Lemay contended that it was unreasonable for 484 See NUREG-1150, Vol. 3, App. D at D-6 (NYS00252C) (stating that NUREG-1150 considers the effects of plant operational procedures to provide water and cooling to a reactor core to prevent its damage and on mitigating the consequences of core damage accidents).

Entergy and the NRC Staff to ignore the Draft NUREG/CR-5148 case study given its purported nexus to IPEC.491 169. But, as discussed at hearing, Draft NUREG/CR-5148 is not the site-specific analysis New York and Dr. Lemay first claimed it to be. As the draft report itself states:

The results that are reported should not be considered as representative of reactor accident consequences either for pressurized water reactors (PWR) in general or for the Indian Point reactors, since the plume direction was selected to maximize the offsite consequences in an area having a particularly high population density.492 Further, the source terms implemented in the IPEC case study were generic source terms used in a 1982 Sandia reactor siting study.493 They are not plant-specific source terms based on a plant-specific PRA analysis, like the source terms used in the IPEC SAMA analysis.494 170. Thus, the analyses presented in Draft NUREG/CR-5148 are not representative of the IPEC site and cannot be accurately characterized as site-specific.495 Nor are they consistent with the SAMA analysis objective, which is to estimate the mean annual offsite population dose and economic costs over the entire SAMA analysis region based on plant-specific information. Dr. Lemay conceded this fact, stating that many of the parameters that are in [Draft NUREG/CR-5148] are wrong, and that Im not advocating this particular example as a NEPA-type and site-specific analysis for Indian Point.496 In any case, Dr. Lemay did not 1150, Draft NUREG/CR-5148 contains no manuscript completion date or the publication date in the front matter of the report.

explain how this example study or the since-retired DECON code described therein could be used to develop a site-specific decontamination cost estimate, and in a form suitable for use in MACCS2.497 171. For all of the above reasons, the Board disagrees with New York that the CDNFRM values used in the IPEC SAMA analysis lack a technical basis or a rational relationship to the IPEC site. The Board also rejects the notion that more detailed or localized decontamination cost estimateseven if it were feasible to develop for use herewould be superior to the NUREG-1150 values used in the IPEC SAMA analysis. NUREG-1150s supporting technical documentation indicates that the CDNFRM values reflect consideration of multiple land uses and decontamination methods. It also establishes that NUREG-1150s average values are reasonable for estimating decontamination costs for the very large and varied geographic region considered in a SAMA analysis. And, as discussed earlier, the CDNFRM values are applied on a per-person basis by MACCS2. Therefore, they allow for site-specific decontamination cost estimates that reflect the high-population areas with the IPEC SAMA analysis region, including New York City. Accordingly, the Board finds that Entergys and the NRC Staffs reliance on the NUREG-1150 CDNFRM values (as escalated for time) is reasonable under NEPA standards.

F. New Yorks Proposed Alternative CDNFRM Values Are Not Reasonable or Appropriate for Use in a SAMA Analysis 172. Claiming that Entergys CDNFRM values are too low, Dr. Lemay proposed his own values.498 Dr. Lemays methodology is described in his direct testimony and the ISR 497 See id. at 2299:2-5 (Teagarden) (What were talking about is what gets rolled up into the cost for non-farm decontamination, CDNFRM, and the associated dose reduction factor.); id. at 2303:18-21 (Lemay)

(MACCS2 has no way of specifying techniques or anything at that level of detail. It has only one aggregate value, the cost of decontamination per person.).

Report.499 For purposes of his analysis, Dr. Lemay divided the spatial grid defined in the IPEC MACCS2 site input file into two discrete areas within the 50-mile radius SAMA analysis region for purposes of evaluation: (1) the NYC metropolitan area and (2) the areas outside of the NYC metropolitan area.500 For each of the areas, he calculated the costs of light and/or heavy decontamination (equating light decontamination to a DF of 3 and heavy decontamination to a DF of 15)501 using the per square kilometer decontamination costs obtained from four sources:

  • Approach A is based on data from the Site Restoration Report as modified by R.E. Luna, H.R. Yoshimura, and M.S. Soo Hoo, Survey of Costs Arising from Potential Radionuclide Scattering Events, WM2008 Conference (Feb. 2008) (Luna Paper)

(NYS000255);

  • Approach B relies upon data from Barbara Reichmuths presentation of results from radiological dispersal device economic consequence analysis in the U.S. (Reichmuth, et al., Economic Consequences of a Rad/Nuc Attack: Cleanup Standards Significantly Affect Cost, Proceedings of Working Together R&D Partnerships in Homeland Security, Boston, MA (Apr. 2005) (Pacific Northwest National Laboratory, PNNL-SA-45256)

(Reichmuth Paper) (NYS000257);

  • Approach C uses information from the CONDO Report (NYS000250), which relates to a decontamination cost estimation tool from the United Kingdoms National Radiological Protection Board, and its database; and
  • Approach D relies upon data from Chernobyl-related decontamination analyses completed by the Risø National Laboratory in Denmark.502 173. For each approach, Dr. Lemay calculated a single total cost for light and/or heavy decontamination within the 50-mile radius area.503 He then divided the total cost by the total population, as reported by Entergy, in the 50-mile radius area to obtain a per capita cost for light 499 See generally New York Direct Testimony at 30:668-51:1056 (NYS000241); ISR Report at 13-24 (NYS000242).

and/or heavy decontamination.504 Finally, Dr. Lemay updated the per capita cost for each approach to 2005 values, using the same CPI method used by Entergy.505 174. The Board discusses each of Dr. Lemays four methodologies below, and concludes that none of them yields a CDNFRM value that is appropriate for use in SAMA analysis. As explained below, Dr. Lemays CDNFRM values are based on references and assumptions that are inapplicable to a nuclear power plant severe accident or SAMA analysis.

1. Site Restoration Report/Luna Paper (ISR Approach A) 175. In ISR Approach A, Dr. Lemay relied on data contained in the 1996 Site Restoration Report to develop alternative decontamination cost estimates.506 Entergy and the Staff contended that the Site Restoration Report is inapplicable to a nuclear power plant SAMA analysis because it developed cost estimates for remediation of a plutonium dispersal event.507 During the hearing, Dr. Lemay conceded that the Site Restoration Report is not ideal because it relates to plutonium dispersal events, not to reactor severe accidents.508 In fact, he admitted that the reports focus on plutonium decontamination costs is a weakness of the method.509 176. Based on the record evidence, the Board finds that the Site Restoration Report has little, if any, relevance to a nuclear power plant SAMA analysis given its focus on plutonium cleanup.510 Cleanup of a plutonium dispersal event differs in significant respects from cleanup 504 Id. at 32:702-04.

of fission products from a severe reactor accident.511 In contrast, the decontamination required for a major reactor accident is primarily concerned with dose reduction of Cesium-137 (Cs-137).512 177. The Site Restoration Reports focus on plutonium significantly increases the decontamination costs estimated therein, because the reports authors assumed that any area requiring a DF greater than 10 would require complete demolition of contaminated structures.513 As the record evidence shows, this runs counter to actual remediation experience, where DFs of up to 15 have been achieved without resorting to complete demolition.514 178. The Site Restoration Report focused on relatively small areas for remediation and did not fully investigate attributes that would be pursued for a significantly larger-scale cleanup effort where complete demolition of all structures is not a viable option; e.g., segregating non-radiological waste from radiological waste, employing waste volume reduction techniques, and 511 Entergy Testimony at 68 (A90) (ENT000450). For example, Pu-239 is primarily an alpha emitter, the presence of which can be difficult to identify in the field. U.S. Environmental Protection Agency, OSC Radiological Response Guideline at 101 (Oct. 2006) (ENT000463).

512 NRC Staff Testimony at 13 (A6a), 15 (A6c) (NRC000041). Cs-137 is a gamma emitter, so it is primarily an external health hazard. OSC Radiological Response Guideline at 83-86 (ENT000463). As a gamma emitter, identification in the field is more readily performed. Id. at 84-85. The Site Restoration Report specifically recognizes this fact:

[T]he high-energy gamma radiations emitted from deposited radioactive cesium are easily detected with simple field instruments, even if the material migrates below surfaces. In contrast, plutonium measurement in the field might be very difficult, particularly if some of the material was lodged in crevices, under vegetation, or inside buildings. Decontamination [for plutonium] would probably be useless unless the post-cleanup level of residual contamination could be reliably quantified.

minimizing the costs associated with on-site disposal.515 The report explicitly recognizes this fact in stating that [o]ur choice of the potential size of the affected area should not be used to predict the costs of accidents.516 179. As discussed in Entergys and the NRC Staffs prefiled testimony, the ISR Approach A cost estimates also rest on a number of other technically unsupported assumptions.

For example, Dr. Lemay inappropriately considered compensation costs in the decontamination cost values developed from the Site Restoration Report. Per the Site Restoration Report, the compensation category addresses compensation to private and business property owners for damage to or disposal of property, and to business firms for lost income.517 As Dr. OKula and Mr. Teagarden explained, such costs are not included in the MACCS2 parameter CDNFRM.518 Rather, they are captured in other MACCS2 parameters, namely the variable POPCST, which addresses temporary or permanent relocation of residents and businesses in the region, including moving expenses and personal and corporate income losses 515 Id. at 130 (A160). See also Site Restoration Report at 7-1 (NYS000249) (In order to derive the cost estimates presented, we assumed that the size of the affected area could range from a few hundred square meters to a few square kilometers.).

516 Site Restoration Report at 7-1 (NYS000249). As part of ISR Approach A, Dr. Lemay also relied on data contained in a brief technical paper by Luna et al. (Luna Paper) that purports to survey efforts to estimate the clean-up costs for radiological dispersion events associated with radiological dispersion devices (RDDs) or dirty bombs. See ISR Report at 16-18 (NYS000242) (citing R.E. Luna, H.R. Yoshimura, and M.S. Soo Hoo, Survey of Costs Arising from Potential Radionuclide Scattering Events, WM2008 Conference (Feb.

2008) (NYS000255)). Like the Site Restoration Report, the Luna Paper concerns small-scale dispersion events and, therefore, lacks applicability in the present context. See Entergy Testimony at 92-93 (A119)

(ENT000450). Further, most of the data sets surveyed by Luna implicitly incorporate the Site Restoration Report economic model and, for that reason alone, lack applicability to a nuclear power plant SAMA analysis.

for a transitional period.519 Incorporating such costs into the variable CDNFRM results in double counting of costs, and also skews the internal cost-benefit determinations made within MACCS2 related to application of decontamination strategies.520 180. Also, in developing cost estimates for light and heavy decontamination based on the Site Restoration Report, Dr. Lemay assumed that the cost of cesium decontamination always equals or exceeds the cost of plutonium decontamination.521 But neither of the two references cited by Dr. Lemay supports that assumption. The first document cited by Dr. Lemay, the Holt study,522 documents Sandias efforts to remove both cesium and plutonium from concrete using a decontamination technique called strippable coatings.523 Dr. Lemay pointed to one result in which Sandia achieved a DF of 1.2 for cesium and a DF of 5.8 for plutonium, which ostensibly suggests that cesium is about five times more difficult to remove than plutonium.524 519 NUREG/CR-6613, Vol. 1 at 7-13 to 7-14 (NYS000243).

520 Entergy Testimony at 97 (A121) (ENT000450). In his rebuttal testimony, Dr. Lemay acknowledged this error, and removed the compensation costs and re-calculated CDNFRM for ISR Approaches A and B, as shown in the tables contained in Exhibit NYS000430. Dr. Lemays original ISR Approach A decontamination cost values were $135,927 to $271,854 per person for light decontamination, and $448,889 to $897,778 per person for heavy decontamination. As a result of correcting only one of the errors identified by Entergys experts, those values changed dramatically to $91,936 - $183,871 per person for light decontamination, and to

$208,780 to $417,561 for heavy decontamination. As Mr. Jones noted, [t]hats a very sensitive number.

Oct. 18, 2012 Tr. at 2116:19 (Jones). Dr. Lemays original ISR Approach B decontamination cost values

$200,000 to $252,000 per person for heavy decontamination. He revised those values to be $97,000 to

$150,720 per person.

521 See New York Direct Testimony at 39:822-25 (NYS000241). Using the data from the Site Restoration Report, Dr. Lemay concluded that an appropriate multiplicative factor for the overall costs shown for plutonium in Table 2 of the ISR Report is necessary to estimate the costs of cesium decontamination. Id. at 37:792-95. Dr.

Lemay considered two cases: (1) the cost of cesium decontamination equals that of plutonium, and (2) the cost of cesium decontamination is twice that of plutonium. Id. at 39:822-25.

181. As noted by the other parties experts, however, Dr. Lemays conclusion is incorrectly based on a single coupon test comparison for concrete.525 The Holt study actually included twenty-four test data sets. Review of the complete body of data reveals cases in which a much larger DF was achieved for cesium than for plutonium. This fact contravenes to Dr. Lemays assumption that the cost of cesium decontamination is twice that of plutonium, and invalidates his decision to multiply the CDNFRM input value used in MACCS2 by a factor of two.526 182. Dr. Lemays second supporting reference includes several datasets from the CONDO software tool. Specifically, Dr. Lemay referenced Table A7, Decontamination factors from a document associated with the CONDO software.527 Table A7 lists a series of decontamination techniques, the surface type being decontaminated, the time over which the DF is applicable, and the DFs.528 Of the 61 decontamination technique/surface pairings listed in the CONDO Report, only seven of them can be differentiated as resulting in a higher DF for plutonium than for cesium.529 Further, 52 of the remaining 54 sets of results are numerically identical and, in two cases, the DF reported for cesium was marginally higher than that reported for plutonium.530 Thus, the referenced data clearly do not support Dr. Lemays assertion that the DFs for cesium are always less or equal to the DFs for plutonium in the CONDO dataset.531 525 Entergy Testimony at 106 (A131) (ENT000450); NRC Staff Testimony at 50-61 (A52) (NRC000041).

183. For the foregoing reasons, the Board finds that the ISR Approach A decontamination cost values are not appropriate for use in a SAMA analysis. The principal source of information on which Dr. Lemay reliedthe Site Restoration Reportconcerns nuclear weapon-related plutonium dispersal events and has no demonstrated relevance to a nuclear power plant severe accident. Furthermore, Dr. Lemay made unsupported technical assumptions that are integral to his cost estimates, including the assumption that cesium decontamination costs always equal or exceed plutonium decontamination costs. The net result are CDNFRM values that, even after revision by Dr. Lemay to remove double counted compensation costs, are two to four times the maximum value of $100,000 per person allowed by MACCS2. Indeed, only by modifying the MACCS2 source code could Dr. Lemay even run the altered MACCS2 software using his proposed values.532 To our knowledge, there is no evidence of an independent review having been performed of the altered software.

2. Reichmuth Paper (ISR Approach B) 184. ISR Approach B is based principally on the Reichmuth Paper (NYS000257),

which purports to compare the economic costs associated with nuclear weapon and RDD detonations for several U.S. cities, including New York City.533 Reichmuth developed economic cost estimates based on two sources: (1) the economic model provided as a companion to the RADTRAN 5 computer code; and (2) a Federal Reserve Bank of New York (FRBNY) study of the economic effects of the 9/11 terrorist attack on the World Trade Center (WTC) in New York City.534 532 New York Direct Testimony at 50:1030-32 (NYS000241).

533 See Reichmuth Paper (NYS000257). Specifically, the Reichmuth Paper estimates economic consequences associated with three nuclear weapon detonations of varying sizes and a Cs-137 RDD in the New York City area.

534 Id. at 5-7.

94

185. The Board finds that both sources relied upon by Reichmuth are irrelevant to the analysis of nuclear power plant severe accident costs. The first source, the economic companion model to RADTRAN 5, is based on the Site Restoration Report methodology.535 For the reasons stated above, the Site Restoration Report is not applicable to a SAMA analysis.

186. The second source identified above, the FRBNY WTC-related study, also has no apparent relevance to a nuclear power plant SAMA analysis. 536 Specifically, we can discern no sound basis for using a non-radiological event involving enormous structural damage (i.e., the 9/11 WTC attacks) to estimate cleanup for a radiological event (i.e., an RDD detonation), in which the structural damage is essentially non-existent.537 And, as Mr. Jones noted, the chosen location for the postulated RDD detonation (New York City) would result in the deposition of the most contamination in the immediate city area.538 This clearly is a worst-case scenario (involving a terrorist attack) that is not representative of a severe accident at a nuclear power plant located 24 to 40 miles from New York City, as postulated in the IPEC SAMA analysis.

187. Dr. Lemay also referenced a second paper by Reichmuth that is briefly discussed in a Congressional Research Services (CRS) report but is not available to the Board and parties. Specifically, he relied on a graphical presentation of cost estimates for a postulated Cs-137 RDD attack on Vancouver that apparently was extracted from the second Reichmuth paper 535 Entergy Testimony at 112 (A136) (ENT000450).

536 Id. at 112-13 (A136).

537 As Dr. OKula, Mr. Teagarden, and Mr. Jones noted, there is no algorithm provided to demonstrate how the WTC data were used to derive costs, no process explaining how the WTC data were used, and no technical discussion of the approach to extend the WTC cleanup costs to represent cesium decontamination. See Entergy Testimony at 113 (A136) (ENT000450); NRC Staff Testimony at 77 (A69) (NRC000041).

538 NRC Staff Testimony at 77 (A69) (NRC000041). Indeed, the Reichmuth Paper states that the WTC site is not representative of New York City in general or any other major population center in the United States because of the unique and very high value buildings that stood on this site and which will be replaced with equally high value buildings. Reichmuth Paper at 7 (NYS000257). It also acknowledges that the replacement value reported in the FRBNY study is thus likely to be much higher than would be expected for the average high density urban area. Id.

and presented in the CRS report.539 Even putting aside the second Reichmuth papers unavailability, Dr. Lemay again failed to explain how a RDD attack in a major metropolitan area is relevant to the severe accident scenarios postulated to occur in the IPEC SAMA analysis.

Further, as Dr. OKula and Mr. Teagarden noted, approximately 85% of costs contained in the CRS report graphic are outside the scope of the MACCS2 parameter CDNFRM (i.e., they are unrelated to radiological cleanup costs), and the basis for the other 15% of the costs is unknown.540 The CRS report also provides no details regarding the cleanup cost estimate reported in the second, non-public Reichmuth paper.

188. Accordingly, the Board finds that the alternative CDNFRM values developed by Dr. Lemay in ISR Approach B are not reasonable or appropriate for use in a SAMA analysis.

The values have no relevant or reliable technical basis. The cited Reichmuth papers (the second of which is not in evidence) do not involve nuclear power reactors and lack sufficient information to allow a reasonable and reliable comparison to the costs of a nuclear power plant severe accident.

3. CONDO Report (ISR Approach C) 189. In ISR Approach C, Dr. Lemay used data related to the European CONDO software tool for estimating decontamination costs in the United Kingdom.541 He claimed that the CONDO user can enter site-specific inputs such as population and building density and use this information to develop site-specific decontamination cost estimates.542 However, he later 539 See Entergy Testimony at 113-15 (A137) (ENT000450). The CRS Report briefly describes this additional paper by Reichmuth, noting that it considers the economic impacts of a postulated explosive-driven RDD containing 1,000 curies of cesium-137 that is detonated at BC Place Stadium in Vancouver, British Columbia.

conceded that he did not actually run the CONDO computer code, but instead manipulated data contained in CONDO code documentation in self-generated spreadsheets.543 As discussed below, the Board finds that Dr. Lemays use of the CONDO dataset is not technically sound.

190. CONDO provides unit cost estimates for different decontamination techniques and applications of those technologies.544 However, for reasons explained by the NRC Staffs and Entergys witnesses, Dr. Lemay did not apply these unit costs appropriately in developing his cost estimates.545 Specifically, he did not consider the manner in which MACCS2 calculates contamination levels and assesses the decontamination efforts needed to return an area to habitability. As a result, Dr. Lemay failed to account for the mass balance of contamination that is accounted for in the modeling within the MACCS2 code.546 This is a significant error in his analysis.

191. Mr. Jones explained that mass balance is important because MACCS2 calculates an amount of contamination per unit area as if the contamination is being deposited on a flat plane, such as a perfectly horizontal surface.547 Applying additional multipliers that effectively increase the base areas used in MACCS2without equally reducing the amount of contamination in this arearesults in artificially high decontamination cost estimates.548 Mr. Jones explained the disconnect between the MACCS2 mass balance model and the CONDO fragmentation model:

544 NRC Staff Testimony at 78 (A69) (NRC000041). Dr. Lemay referenced Table A7, Decontamination factors of the CONDO Report (NYS000250). The table lists a series of decontamination techniques, the type of surface being decontaminated, the time over which the DF is applicable, and the DFs. The DFs are provided for cesium to represent the cesium and ruthenium element classes (i.e., beta/gamma emitters), and for plutonium to represent the plutonium element class (i.e., all alpha emitters).

CONDO allows you to include decontamination of the walls, decontamination of the interior and exterior. So if you put a building on this flat plane where MACCS calculates 100 curies, now youve got four walls and a roof. And youve got four interior walls, a floor and a ceiling. You have 11 surfaces. In Dr. Lemays analysis, he applies the heavy decontamination activities towards all of those surfaces. So hes removing effectively 100 curies from each of those surfaces to reduce this below habitability [dose threshold]. So 1,100 curies of cesium are being removed when only 100 is present.549 In other words, Dr. Lemays methodology assumes the decontamination of more cesium than is postulated to exist by MACCS2 based on the plant-specific source term inputs to the code.

192. Dr. Lemay initially disagreed with Mr. Jones, asserting that MACCS2 is not a mass conservation code.550 He claimed that the code contaminate[s] the surfaces and then decontaminate[s] them depending on how many surfaces we have to decontaminate.551 Dr. Lemay also said that MACCS2 assumes that the contaminant plume is continually replenished.552 193. Dr. Bixler agreed with Mr. Jones that MACCS2 conserves mass through a source depletion model.553 He explained that the simulated plume is depleted through various mechanisms modeled in MACCS2, including deposition on the ground, rainfall, and radioactive decay.554 He also clarified that plume depletion is accounted for through a transfer coefficient 549 Oct. 18, 2012 Tr. at 2117:25-2118:12 (Jones). See also NRC Staff Position Statement at 12 (NRC000039)

times a unit surface area that just represents [a] flat plane area.555 Dr. OKula and Mr. Teagarden agreed that the MACCS2 plume model is mass conservative.556 In this regard, they noted that the MACCS2-simulated plumes contain a finite amount of radioactivity,557 and that it is impossible to decontaminate more than you start with.558 194. After hearing the testimony of the NRC Staffs and Entergys experts, Dr. Lemay stated that I would like to concede to Dr. Bixler that indeed MACCS has mass conservation between the plume and the contamination deposited on the ground. So what goes on the ground is taken off from the plume. That is absolutely correct.559 In the Boards view, this concession casts significant doubt on the reliability of Dr. Lemays Approach C (CONDO) for decontamination cost estimates.

195. Moreover, Dr. OKula and Mr. Teagarden identified another significant flaw in the ISR Approach C methodology. Despite the availability of 61 decontamination techniques in the CONDO database, Dr. Lemay weighted his results predominantly on decontamination of internal walls in buildings, and relied on a single decontamination technique in all of his spreadsheet calculations.560 Specifically, one technique (vacuuming, cleaning and washing) is the dominant cost contributor for the semi-urban, urban and hyper-urban population densities 555 Id. at 2144:16-17 (Bixler).

areas described in the ISR Report.561 Dr. OKula and Mr. Teagarden explained that this approach is not reasonable because building interiors are expected to be less contaminated than the building exteriors in the event of a nuclear power plant severe accident,562 and that any decontamination effort would proceed through a highly prioritized process.563 Dr. Bixler and Mr. Jones agreed, explaining that all surfaces would not be decontaminated equally. Rather, decontamination efforts would focus on the most contaminated surfaces (e.g., on the ground floor of a building and near ventilation systems, where contamination is more likely to enter the building) with the goal of restoring habitability.564 196. Notably, Mr. Jones testified that if appropriate corrections are made to Dr. Lemays ISR Approach C decontamination cost estimates, the resulting CDNFRM values are much more in line with those used in the IPEC SAMA analysis. Mr. Jones stated that he redid the CONDO-related calculation provided by Dr. Lemay in Annex C of the ISR Report for heavy decontamination (where the New York City metropolitan area is considered urban and the remainder of the region is considered semi-urban).565 His objectives were to account for mass 561 Id. at 119 (A144). The CONDO datasets present data for three different population category ranges; i.e., rural

(< 25 persons/km2), semi-urban (> 25 but 1,000 persons/km2), and urban (> 1,000 persons/km2). See id. at 119-20 (A144-45). Dr. Lemay created a fourth population category called hyper-urban to account for a population density exceeding 10,000 persons/km2 for the New York City region. He then characterized the New York City metropolitan area as either urban or hyper-urban by population density, and the area outside the New York City metropolitan area (but still within the 50-mile SAMA analysis region) as either semi-urban or urban. New York Direct Testimony at 43:899-44:943 (NYS000241). The Board agrees with Dr. OKula and Mr. Teagarden that Dr. Lemays characterization is inconsistent with the actual population densities in the SAMA analysis region and leads to inflated cost estimates. Entergy Testimony at 118-21 (A143-45), 131 (A160) (ENT000450). The 50-mile (80-km) SAMA analysis polar grid indicates that only one of eighty 22.5-degree sector elements (1.8% of the total SAMA grid area) meets Dr. Lemays definition of hyper-urban (10,000 persons per km2), and that 68 of the remaining grid elements (81.5% of the total SAMA grid area) would not meet the definition of an urban area.

balance of the MACCS2 estimate of contamination and to evaluate the effect of the two largest multipliers (for building walls and building interiors) used by Dr. Lemay in his calculation.566 The ISR values for this estimate are shown in Table 7 of the ISR Report.567 197. When Mr. Jones input his adjusted values into Table 7 of the ISR Report, he obtained an estimated decontamination cost $23,631 per person for heavy decontamination (DF

= 15), which is nearly four times less than Dr. Lemays original value of $89,734.568 He reduced that number by another 29 percent based on the fact that 29 percent of the land area is not urban or semi-urban.569 The final value of $16,778 per person, which Mr. Jones calculated using the CONDO data but accounting for mass conservation, is reasonably close to Entergys decontamination value of $13,824 per person for a DF of 15.570 198. Based on his review of Dr. Lemays spreadsheets and Mr. Jones testimony, Dr. OKula concurred that if Dr. Lemays values are correctly renormalized to account for mass conservation and the non-uniform nature of contamination within a building, then those values would be much closer in value to the CDNFRM values used in the IPEC SAMA analysis.571 566 Id.

Id. at 2366:5-12 (OKula). At the hearing, New York counsel requested that Entergy disclose any spreadsheets or analyses documenting Dr. OKulas aforementioned review.

OKula as an interim disclosure on November 30, 2012. See Entergy Disclosure No. 9432, CONDO and RISO Spreadsheet, prepared by Dr. Kevin OKula (Oct. 2012). Entergy also listed Dr. OKulas spreadsheet in its Forty-Sixth Supplemental Disclosure Log transmitted to the parties on December 5, 2012.

101

199. In summary, the Board finds that the ISR Approach C decontamination cost estimation methodology is fundamentally flawed because it overlooks the use of mass balance principles in the MACCS2 code. As a result, Dr. Lemays proposed CDFRM values are neither reliable nor appropriate for use in the IPEC SAMA analysis.

4. Risø Report (ISR Approach D) 200. In ISR Approach D, Dr. Lemay repeated the methodology used in ISR Approach C, but substituted decontamination cost values obtained from a 1995 report prepared by Denmarks Risø National Laboratory for the costs reported in the CONDO dataset.572 For this approach, Dr. Lemay chose decontamination techniques from the Risø Report that most closely correlated to those selected in the CONDO analysis.573 For each type of area (hyper-urban, urban, semi-urban), the fraction of land covered by a given type of surface was taken from the CONDO spreadsheet, and the cost per km2 was calculated using the Risø values.574 The rest of the cost evaluation used the same methodology as the CONDO analysis described above.575 Claiming that the Risø techniques are recommended only for light decontamination, Dr. Lemay did not use the Risø data to calculate a CDNFRM value for heavy decontamination.576 201. The Board finds that ISR Approach D does not provide CDNFRM values that are appropriate for use in a SAMA analysis. Regardless, it is clear that Dr. Lemay simply 572 New York Direct Testimony at 46:963-67 (NYS000241). The RISO report provides a catalog of feasible techniques for reduction of dose 9 years after the Chernobyl accident. NRC Staff Testimony at 88 (A79)

substituted Risø cost data for CONDO cost data and maintained the area-specific values derived from the CONDO study.577 As such, ISR Approach D is based on the same flawed methodology and assumptions underlying the ISR Approach C (CONDO) cost estimate.578 Dr. Lemay thus again failed to account for mass conservation principles (as applied in MACCS2) and the non-uniform nature of contamination within a building.579 For that reason alone, the ISR Approach D decontamination cost values cannot be deemed reliable as a technical matter or more appropriate than Entergys CDNFRM values.

G. The TIMDEC Values Used as Inputs to the IPEC SAMA Analysis Have an Established Technical Basis and Are Rationally Related to the IPEC Site 202. New York also asserted that Entergys TIMDEC values (60 days for a DF of 3 and 120 days for DF of 15) are not rationally related to the IPEC site.580 Dr. Lemay asserted that those values are unreasonable in view of the Chernobyl and Fukushima accidents.581 He stated that decontamination of the area affected by the Chernobyl accident took four years and included the decontamination of tens of thousands of buildings in the most contaminated cities and villages of the former USSR.582 With respect to Fukushima, Dr. Lemay noted that some estimates suggest that the decontamination could last for decades.583 203. The Board recognizes the severity of the Chernobyl and Fukushima accidents and the magnitude of the resulting cleanup efforts.584 However, our task is to assess the 577 Entergy Testimony at 122 (A149) (ENT000450).

reasonableness of Entergys decontamination time and cost assumptions under NEPA, as reflected in specific inputs to the MACCS2 code and within the well-established framework of a SAMA analysis and applicable NRC guidance. The SAMA analysis examines the mean annual consequences of various hypothesized accident scenarios, spanning a spectrum of potential initiating events, accident sequences, and severity of consequencesand for the entire 50-mile radius region surrounding a plant.585 It does not endeavor to exactly mimic a real-life scenario.586 Nor does a SAMA analysis attempt to model highly localized and variable decontamination activities or provide highly detailed cleanup costs associated with a single, specific accident such as Chernobyl or Fukushima.587 204. In MACCS2, the decontamination time variableTIMDECrepresents the time period during which persons are temporarily interdicted (i.e., kept away from their residences) while decontamination activities are completed to reduce the dose by the specified dose reduction factor.588 Following the expiration of the TIMDEC period, and upon satisfaction of the specified habitability criteria, MACCS2 models the relocation of persons back to their residences.589 Thus, TIMDEC establishes the minimum time that an individual is relocated due to dose constraints.590 585 See Entergy Testimony at 18 (A31) (ENT000450).

205. MACCS2 requires users to input a decontamination time for each level of decontamination effectiveness modeled.591 The TIMDEC parameter defines the time required for completion of each of the user-selected decontamination levels.592 Thus, with two levels modeled in the IPEC SAMA analysis, two decontamination times are required: one for the lower DF, and one for the higher DF.593 As noted above, Entergy used an input of 60 days for a DF of 3, and 120 days for DF of 15.594 These values are the same values used in NUREG-1150.595 206. Entergys and the NRC Staffs experts discussed the historical and technical bases for the DF and TIMDEC values used in NUREG-1150, as well as in the IPEC SAMA analysis.596 Mr. Harrison and Dr. Ghosh noted that the NRC has been examining the decontamination times for over 37 years, beginning in 1975 with the Reactor Safety Study, which discussed decontamination activities that are capable of restoring areas to habitability quickly given sufficient resources.597 They further stated (as did Dr. OKula and Mr. Teagarden) that the genesis of the values used by Entergy can be traced back to NUREG/CR-3673.598 207. NUREG/CR-3673 identified an average effort required to restore habitability to an area after the most severe type of reactor accident; i.e., an SST1 accident source term as defined in the 1982 Sandia Siting Study (ENT000453).599 It states an average clean-up was 591 Id. at 72 (A94).

NUREG/CR-3673 states that the SST1 - SST3 accident source terms were defined in the 1982 Sandia Siting Study to represent the range of potential release of radioactive materials resulting from core-melt sequences with containment failure. The SST1 release category included accidents that result in containment failure due 105

expected to take 90 days with approximately 46,000 workers (11,000 person-years of effort) for this most severe type of reactor accident.600 Thus, the report cites this period as an average time to complete decontamination efforts following the most severe type of reactor accident.601 Less severe accidents, including ones that may result in little clean-up being required, may take less time or involve fewer resources.602 In either situation, NUREG/CR-3673 identified the average time to complete decontamination efforts to be about 90 days or less for severe reactor accidents.603 NUREG-1150 adopted 60-day and 120-day values for DF = 3 and DF = 15, respectively.604 208. Mr. Harrison and Dr. Ghosh testified that to provide a reliable and reasonable analysis, the decontamination time inputs to MACCS2 must represent all of the modeled severe accidents, including ones that require little decontamination.605 This is a reasonable approach, especially in the context of a SAMA analysis, which is a probabilistic, time- and spatially-averaged analysis that considers a multitude of clean-up scenarios.606 209. In his rebuttal testimony, Dr. Lemay argued that the assumptions made in NUREG/CR-3673 are unreasonable for a severe accident at [IPEC].607 According to Dr. Lemays calculations, applying the NUREG/CR-3673 methodology to the decontamination cost calculated by Entergy for the Early High release category at IP2 led him to conclude that to rapid overpressurization and release of a large fraction of the core inventory to the environment.

1.5 million workers (363,000 worker-years) would be required to decontaminate the affected area in 90 days.608 Dr. Lemay further asserted that even assuming decontamination occurred over a full year, 363,000 workers would still be required to complete decontamination within that period.609 Therefore, he claimed, the assumptions regarding the timeline in NUREG/CR-3673 are invalid,610 because a decontamination effort requiring anything over 100,000 to 150,000 people is not reasonable.611 210. However, as Dr. OKula explained, a SAMA analysis considers a broad spectrum of release categories, including those that involve minimal or no failure of the containment (and thus lower accident source terms).612 It is not concerned only with the most severe release category; i.e., the Early High release category singled out by Dr. Lemay in his testimony.613 211. Moreover, there are frequencies associated with each release category, and the lower release categories make up a significant portion of the overall release frequency.614 In effect, by focusing on the Early High release category in his decontamination worker calculation, Dr. Lemay applied a worst-case assumption.615 Accounting for the full spectrum of release categories and frequencies considered in the IPEC SAMA analysis, Mr. Teagarden and Dr. OKula estimated that the average number of decontamination workers would be 608 See id. at 22:17-21; see also Oct. 18, 2012 Tr. at 2112:19-2114:14, 2186:4-12 (Lemay).

approximately 60,000 to 80,000 people, the number of people that would fill Yankee Stadium on any given Sunday.616 212. In further defending Entergys TIMDEC values, Dr. OKula and Mr. Teagarden explained that NUREG/CR-3673 focused on the need to restore areas to habitability quickly and cost-effectively.617 They explained that the MACCS2 decontamination/economic models are based on a staged implementation of offsite population protective measures in post-accident situations (i.e., relocation, decontamination, interdiction, condemnation), and focus on achieving a decontamination level that is both cost-effective and feasible.618 This is reflected in NUREG/CR-3673, which states that the most effective approach is to complete decontamination of those areas which can be restored to acceptable levels as quickly as possible.619 213. Dr. OKula and Mr. Teagarden further explained that this staged approach to decontamination and re-habitation of interdicted areas always has been part of the MACCS/MACCS2 code logic,620 and that the NUREG-3673/CR authors viewed the staged implementation of post-accident protective measures as providing more reasonable cost 616 Id. at 2191:2-6 (Teagarden).

617 Entergy Testimony at 86-87 (A107) (ENT000450). In MACCS2, habitability decisionmaking can result in four possible outcomes: (1) land is immediately habitable; (2) land is habitable after decontamination; (3) land is habitable after decontamination and interdiction ; or (4) land is not deemed habitable after 30 years of interdiction (i.e., it is condemned). Land also is condemned if the cost of decontamination exceeds the value of the land. See id. at 37-40 (A51).

estimates.621 Thus, the assumption that decontamination activities will be performed in an expedited manner is integral to the MACCS2 decontamination and interdiction model.622 214. For these reasons, Dr. OKula and Mr. Teagarden concluded that NUREG/CR-3673 and NUREG-1150 (including its supporting technical bases in NUREG/CR-4551) support the conclusion that the two decontamination levels (DFs) and times (TIMDEC) defined in the IPEC SAMA analysis are appropriate to model early efforts within days to weeks after plume deposition, and before weathering and human activities (planned and inadvertent) affect the distribution of the contamination.623 They explained that the decontamination levels and times applied in the IPEC SAMA analysis are consistent with the limited time available for effective use of decontamination techniques and, and are technically justified within the context of a SAMA analysis, which uses probabilistic methods and cost-benefit analysis techniques.624 Dr. OKula and Mr. Teagarden recognized that in the event of an actual severe accident, decontamination activities could extend over longer periods, and noted that the TIMDEC variable is not intended to represent the physical cessation of all decontamination activities following a severe accident.625 621 NUREG/CR-3673 at 4-6 (ENT000466).

215. Further, we assume that if the Commission expected licensees to use new values in their SAMA analyses as a result of Fukushima or Chernobyl, it would have issued such guidance on a generic basis, but it has not. The Chernobyl accident occurred in 1986, over 25 years ago, and the NRC has not issued any guidance on decontamination time frames since then. Nor has the Commission issued any NEPA-related guidance as a result of Fukushima, which leads the Board to believe that values consistent with NUREG-1150 are acceptable.626 216. In conclusion, based on the parties testimony and evidence, and our understanding of how the TIMDEC input is used in MACCS2, the Board finds that Entergys two decontamination factors (DF = 3 and DF = 15) and the associated decontamination times (60 and 120 days) are reasonable under NEPA standards. These values are consistent with the NUREG-1150 values and have been applied in Level-3 type PRA analyses (including SAMA analyses and the SOARCA project) for many years. The TIMDEC values used in the IPEC SAMA analysis were designed to be average values that reflect the entire spectrum of severe accident scenarios examined in a SAMA analysis, which ultimately calculates mean average offsite dose and economic consequences over an approximately 7,800 square mile region.

H. New Yorks Proposed Alternative TIMDEC Values Are Not Reasonable or Appropriate for Use in a SAMA Analysis 217. In addition to alternative CDNFRM values, Dr. Lemay proposed TIMDEC values ranging from 2 to 30 years, which are substantially larger than the values used in NUREG-1150 626 In contrast, the Commission has issued safety-related directives in response to Fukushima. As noted in a recent First Circuit decision concerning the Pilgrim nuclear power plant, in March 2012, the NRC issued three orders to the industry implementing the recommendations of a task force chartered by the NRC to conduct a methodical and systematic review of the NRCs processes and regulations to determine whether the agency should make additional improvements to its regulatory system in light of the events at Fukushima.

and the IPEC SAMA analysis.627 As an initial matter, his proposed values are so large that they are outside the accepted input range of the MACCS2 code, which allows a maximum TIMDEC value of one year.628 Consequently, Dr. Lemay again needed to alter the MACCS2 source code to accept his much larger TIMDEC values.629 Dr. OKula and Mr. Teagarden maintained that altering the MACCS2 source code without an independent verification of proper code functionality is ill-advised and counter to standard industry configuration control and software quality assurance practices.630 Even putting that concern aside, the Board finds it unreasonable to expect applicants like Entergy to self-modify the MACCS2 code, particularly given the Commissions recent characterization of MACCS2 as the standard, NRC-endorsed tool for SAMA analyses.631 218. The Board also agrees with Entergys witnesses (Dr. OKula and Mr. Teagarden) and the NRC Staffs witnesses (Mr. Harrison and Dr. Ghosh) that alternative decontamination times proposed by Dr. Lemay are inconsistent with the MACCS2 codes integral decontamination and interdiction modeling assumptions.632 Dr. OKula and Mr. Teagarden convincingly testified that forcing a long decontamination period (e.g., beyond a year) in the MACCS2 analysis via the TIMDEC variableas done by Dr. Lemaydistorts the codes dose reduction resettlement optimization strategy.633 By design, MACCS2 will not model the relocation of persons back to their residences until TIMDEC expires.

long TIMDEC period precludes proper modeling of the resettlement of interdicted persons following the cessation of decontamination activities. For example, if a value of 10 years is used for TIMDEC, then MACCS2 will not model the return of any affected individuals to their residences until 10 years have passed.634 In reality, many individuals within the 50-mile radius SAMA analysis region would be able to return to their homes relatively quickly; i.e., within days to months.635 219. Dr. Bixler agreed, and stated that using TIMDEC values exceeding the one-year maximum allowed by MACCS2 defeats the logic in the code.636 He reiterated that one year was set as the upper bound, because the framework of the code was based on one year, not more than a year.637 Dr. Bixler explained that, within the MACCS framework, applying TIMDEC values as large as 15 or 30 years causes property values to decrease to zero or almost zero.638 This, in turn, precludes MACCS2 from modeling the successful decontamination of those properties (particularly for a DF of 15) and instead results in condemnation of the properties.

220. Dr. Bixler also explained that the TIMDEC and CDNFRM parameters are interrelated, and that MACCS2 analysts must consider that nexus in selecting input values.639 Mr. Teagarden agreed, stating that the decontamination factor, cost, and time form a suite of variables that reflect how MACCS2 models decontamination,640 and that the code user should not arbitrarily alter one of these variables without evaluating the impact of the change on the 634 Id.

other, related variables.641 As discussed above, it is clear that the DF, CDNFRM, and TIMDEC values used in NUREG-1150, the IPEC SAMA analysis, and the SOARCA study were, in fact, developed as a suite of parameters and designed to be consistent with the MACCS2 habitability decisionmaking model. The same cannot be said of Dr. Lemays proposed CDNFRM and TIMDEC values, which are based on a mixed bag of sources and assumptions.

221. In summary, the Board finds that the challenged NUREG-1150 decontamination time (TIMDEC) values have an established technical pedigree and a long history of use in severe accident analyses applying the MACCS2 code. In contrast, Dr. Lemays proposed decontamination time values are inconsistent with the MACCS2 codes internal logic, outside the accepted input range of the MACCS2 code, and at odds with actual decontamination experience. As Dr. OKula and Mr. Teagarden testified, the out-of-range values could be input only with modification of the MACCS2 code itself, and because the software was not independently verified, this questionable practice in itself renders any new output as highly suspect.642 Furthermore, the Board concludes that it is not reasonable to expect license renewal applicants to modify the MACCS2 source code, especially for purposes of a NEPA assessment, especially given the testimony from the NRC and Entergy experts regarding the inter-related complexity of the code.

I. Entergys Values for Other MACCS2 Economic Inputs Are Reasonable and Appropriate for Use in the IPEC SAMA Analysis 222. As noted above, the evidentiary hearing focused on Entergys CDNFRM and TIMDEC values given their acknowledged, much larger effect on the SAMA analysis results.

However, the parties testimony also discussed values for several other MACCS2 economic parameters: value of nonfarm wealth (VALWNF), relocation costs (POPCST), investment rate 641 Id. at 2248:5-9 (Teagarden); see also id. at 2269:15-22 (Teagarden).

113

of return (DSRATE), and fraction of nonfarm property due to improvements (FRNFIM). We briefly discuss each of these MACCS2 parameters below and conclude that Entergys associated input values are reasonable under NEPA standards.

1. Value of Nonfarm Wealth (VALWNF) 223. Dr. Lemay asserted that Entergys calculations of nonfarm wealth were outdated since the values obtained from SECPOP2000 were not scaled up from 1997 values to 2004 values.643 VALWNF defines the value of per capita nonfarm wealth in the region (expressed in dollars per person).644 Nonfarm wealth includes all public and private property not associated with farming that would be unusable if it was rendered temporarily or permanently uninhabitable.645 224. Entergy developed estimates of the nonfarm wealth value for each county based upon fixed reproducible tangible wealth, a measure of the durable goods that are owned in an area.646 It obtained county-specific values for nonfarm wealth data from the data set of the SECPOP2000 computer software.647 SECPOP2000 was previously developed by Sandia for the NRC and calculates estimated population and economic data about any point (specified by longitude and latitude) that lies within the continental United States.648 225. To ensure that economic information pertaining to New York City was included in the analysis, Entergy combined the nonfarm property values for four counties within the metropolitan New York City region as a weighted average (weighted by population) and 643 New York Direct Testimony at 58:1208-09 (NYS000241).

assigned it to the Queens economic region.649 Entergy then computed an average regional value of nonfarm wealth for the 50-mile radius area for use in the MACCS2 analysis.650 This value was calculated as VNFRM weighted by the area that each of the twenty-eight counties has in the IPEC 50-mile radius area.651 The original calculated baseline VALWNF value was

$163,631/person.652 226. Entergy later modified its original baseline VALWNF value. Specifically, after the initial analysis described above, Entergy estimated the impact of lost tourism and business as a sensitivity case in response to an NRC Staff RAI.653 To assess lost business, Entergy obtained measures of total economic activity by examining a suite of products related to the national Gross Domestic Product (GDP), which is a measure of the total value of goods and services produced in an area.654 Mr. Teagarden testified that this calculation is not customarily done by NRC license renewal applicants and represents a conservatism in Entergys SAMA analysis.655 227. The GDP per person values for 2004 were developed to estimate the total value of goods and services produced in the 50-mile radius area.656 This essentially is all the items that were manufactured or produced in the area in 2004, plus services that produce economic 649 Entergy Testimony at 50 (A68) (ENT000450) (citing Enercon MACCS2 Input Report at 5-5 to 5-6 (NYS00270A)).

activity in that year.657 The modified VALWNF values, therefore, were a measure of the peoples nonfarm wealth as well as a measure of their economic output.658 228. The average value of nonfarm wealth thus was developed based upon the most recent and complete economic dataset available at the time of the SAMA analysis for the counties within the 50-mile radius using the modified nonfarm wealth values.659 The revised estimate of average nonfarm wealth value for the full 50-mile radius region was quantified as

$208,838/person, a factor of 1.28 increase from the original estimated value of $163,631.660 229. Dr. Lemay correctly noted that Entergy did not scale up the 1997 SECPOP2000 values to 2005 values.661 However, the Board finds that this omission is not material. As Entergys experts explained, if the VALWNF value of $163,631/person was escalated from 1997 to 2005 using the CPI as suggested in NEI 05-01, the increase factor would be 1.22 (i.e., CPI value of 195.3 for 2005/CPI value of 160.5 for 1997).662 The increase factor (1.28) associated with lost tourism and business applied by Entergy in its updated SAMA base case bounds that associated with escalating the VALWNF value from 1997 to 2005.663 Therefore, we find that Entergys VALWNF value is reasonable under NEPA and appropriate for use in the SAMA analysis.

phase.664 POPCST was developed in NUREG/CR-4551 with a value of $5,000/person on the basis of per capita lost wages ($14,600/person-year, national value) for 140 days (i.e., twenty weeks).665 Entergy escalated the POPCST value using the CPI to a value of $8,640/person, which reflects per capita lost income of $61.70/person-day (i.e., $8,640/person divided by 140 days).666 MACCS2 applies this value to each individual relocated after a postulated severe accident, whether he or she is an adult or child, or is employed or unemployed. 667 231. Dr. Lemay agreed with Entergy that the moving expenses would contribute very little to the cost of long-term relocation (because the majority of the personal belongings would be contaminated), but felt that given current unemployment benefits policies in the State of New York, it seemed that 140 days of lost wages was too low.668 He noted that New York State unemployment benefits normally last twenty-six weeks (182 days) and have recently been extended to ninety-three weeks (651 days).669 Based on those assumptions, Dr. Lemay calculated the cost of long-term relocation by multiplying the 2005 average income per capita

($76/day) by a range of durations for the lost wages. The resulting costs were $10,640/person (for 140 days of lost wages) to $49,857/person (for 93 weeks of lost wages).670 232. Mr. Teagarden and Dr. OKula viewed use of the New York State value rather than the national value as reasonable.671 (Dr. Lemays daily rate is approximately 23% higher 664 Id. at 97 (A121), 125 (A154).

666 Id. Thus, for a household of three, the POPCST would provide $25,920 (i.e., $8,640/person times three persons), reflecting a per-household lost income of $185.10/day (i.e., $25,920 divided by 140 days).

than the value used by Entergy.)672 However, with regard to the length of time that the workers are assumed out of work, they disagreed that the current, temporary term of unemployment benefits in New York State is an appropriate basis for comparison.673 They testified that, in their expert opinions, historical unemployment durations provide a more reasonable basis.674 233. According to the Bureau of Labor Statistics (BLS), the median and average duration of unemployment in the U.S. in 2005 (the reference year for the SAMA economic inputs) was 8.9 weeks and 18.4 weeks, respectively.675 Although these 2005 values may be lower than current values associated with the recession, these 2005 values are still higher than broader historical unemployment durations.676 Based on BLS data from 1970 through 2010, the average unemployment duration over this 41-year time period is 15.5 weeks, with the average median duration being 7.9 weeks (approximately fifty-five days).677 234. Based on the BLS data, the Board agrees that Entergys assumption of 20 weeks (i.e., 140 days) is reasonable and, in fact, somewhat conservative. Further, based on the 41-year historical average, the duration value of twenty weeks used by the Entergy is 29% higher than the average value of 15.5 weeks.678 As Mr. Teagarden and Dr. OKula explained, this conservatism in the loss of work duration appears to offset the regional lost income variation cited by Dr. Lemay.679 Thus, the Board finds that Entergys POPCST value reasonable under NEPA.

3. Investment Rate of Return (DSRATE) and Fraction of Nonfarm Property Due to Improvements (FRNFIM) 235. Entergy used NUREG-1150 values for the DSRATE and FRNFIM inputs to MACCS2.680 As explained earlier in our decision, we view Entergys reliance on NUREG-1150 values as reasonable. Furthermore, Dr. Lemay noted that the overall effect of using allegedly more appropriate values for the remaining sensitive parameters was negligible on the final cost calculation.681 This is reflected in that fact Dr. Lemays proposed values for DSRATE and FRNFIM (5-7%, and 90%, respectively) are comparable to those used by Entergy (12%, and 80%, respectively).682 Therefore, the Board finds that Entergys DSRATE and FRNFIM values are reasonable under NEPA and appropriate for use in the IPEC SAMA analysis.

J. New York Has Not Provided Sufficient Evidence to Conclude That There Are Additional Potentially Cost-Beneficial SAMAs, Especially In View of the Conservatisms Inherent in the IPEC SAMA Analysis 236. The Board has thoroughly evaluated the technical bases for New Yorks claims and examined them through the lens of NEPAs rule of reason. For the reasons set forth in Sections IV.D through IV.I above, New York has not identified a significant deficiency in the IPEC SAMA analysis that renders the analysis altogether unreasonable under NEPA standards.683 New York also has not proposed reasonable alternative inputs or methodologies that, if adopted, would lead to a more accurate or meaningful SAMA analysis.684 Indeed, New Yorks proposed CDNFRM and TIMDEC values lack sufficient technical justification and significantly exceed the maximum values allowed by the MACCS2 code for those parameters.

237. The Board also finds that New York has not identified a deficiency in the IPEC SAMA analysis that plausibly could alter the overall results in a material way.685 This finding is bolstered by the significant conservatisms undergirding the SAMA analysis, as explained by the NRC Staffs and Entergys experts. For example, as Dr. Ghosh explained, SAMA analyses typically use two multipliers on the internal benefit quantification in order to account for (1) external events and (2) analysis uncertainties.686 The analysis uncertainties multiplier is typically based on the ratio of the 95th percentile CDF to the mean or point estimate CDF.687 Any SAMAs that become cost beneficial after the use of these two multipliers are included as cost-beneficial.688 238. Entergys use of mean consequence values also adds conservatism to the analysis, As Dr. Bixler explained, the distribution of Entergys MACCS2 offsite consequence results is roughly a lognormal distribution; i.e., the mean value is well above the median of the distribution.689 The median is defined as the value for which the outcome is lower half of the time and for which it is greater half of the time, whereas the mean is simply the arithmetic average of all the outcomes.690 Dr. Bixler testified that he evaluated Entergys MACCS2 results and estimated that the mean results were generally between the 66th and 72nd percentiles.691 685 Pilgrim, CLI-12-15, slip op. at 13.

687 Id. at 22 (A14). Although the analysis uncertainties multiplier is typically estimated as the ratio of the 95th percentile CDF to the mean or point estimate CDF, this multiplier is meant to account for analysis uncertainties generally, not just uncertainties in the level 1 PRA.

This means that the SAMA analysis results are skewed in the direction of greater offsite dose and economic consequences.692 239. In their prefiled and oral testimony, Entergy and NRC Staff witnesses identified other conservatisms that we briefly mention here. They include Entergys use of: (1) a deposition velocity that results in greater radionuclide deposition within the 50-mile SAMA analysis region;693 (2) the projected population in year 2035, which is the last year of the IP3 period of extended operation and two years after the end of the IP2 period of extended operation;694 (3) a no-evacuation assumption, which overestimates doses incurred in the early phase of potential accidents;695 (4) two decontamination factors instead of the three permitted by MACCS2;696 and (5) the results of a sensitivity case for lost tourism and business in the base case analysis.697 240. The significant conservatisms discussed above are manifest in the final SAMA analysis cost-benefit results. As Dr. Ghosh explained during the hearing, the theoretical benefit of actually implementing all of the IP2 and IP3 SAMAs identified by Entergy as potentially cost-beneficial would exceed the maximum attainable benefit (i.e., eliminate the baseline risks of plant operation) for IP2 and IP3, and, in the case of IP2, eliminate the baseline risks twice over.698 This reflects the fact that SAMA analysis is done on a per SAMA candidate basis, and 692 See Oct. 18, 2012 Tr. at 2290:21-2291:23, 2293:6-21 (Ghosh).

that many of the SAMA candidates are acting on the same accident sequences.699 Therefore, as the lower-cost alternatives for mitigating the dominant accident sequences (e.g., steam generator tube rupture) are implemented, the baseline risk, as recalculated, is reduced.700 This reduces the likelihood that other SAMA candidates acting on the same accident sequences will remain, or become, potentially cost-beneficial.701 Dr. Ghosh opined that the existing margin in the IPEC SAMA analysis can accommodate uncertainties of the type posited by New York relative to decontamination cost estimates.702 241. Dr. Ghoshs testimony is compelling, and provides further support for the Boards conclusion that New York has not shown that the IPEC SAMA analysis is unreasonable under NEPA standards, or that the alleged deficiencies in Entergys decontamination-related inputs have masked the existence of additional cost-beneficial SAMAs.703 699 Id. at 2164:24-2165:1 (There are multiple SAMAs that are already identified to mitigate the same types of accidents.); id. at 2223:11-21 (Ghosh).

700 Id. at 2165:21-2166:2 (Ghosh) (The point Im trying to make is that if you look at the existing list of candidates that are there and if you actually started to implement some of them, the incremental benefit of implementing additional SAMAs just goes down. And we cant completely eliminate the plant risk twice over.)

701 Id. at 2224:22-2225:2 (Ghosh) ([W]e dont believe were going to come up with any more SAMAs that would be potentially cost beneficial and that they would be cheaper alternatives to mitigating the same types of accidents that were already looking at mitigating with the list that we have.); see also id. at 2235:19-2236:8 (Ghosh) ([I]ts hard to imagine that they would really become cost beneficial since there is already alternatives on the table to mitigate those same types of accident sequences.).

702 Id. at 2235:5-10 (Ghosh) (You're right that my fundamental point is that the ISR New York State analysis introduces some uncertainty and into particular elements of the benefit calculation. And I believe that the existing margin in the analysis can accommodate this uncertainty already.).

703 In establishing the SAMA analysis requirement in 1996, the Commission concluded that it is unlikely that site-specific SAMA evaluations would identify major plant design changes or modifications as being cost-beneficial. See Final Rule, Environmental Review for Renewal of Nuclear Power Plant Operating Licenses, 61 Fed. Reg. 28,467, 28,481 (June 5, 1996) (NYS000127). In view of plant enhancements identified and implemented as part of the NRCs industry-wide IPE program, the Commission expected that any additional plant enhancements identified by license renewal SAMA analyses as cost-beneficial generally would be procedural and programmatic fixes, with any hardware changes being only minor in nature and few in number. Id. Entergy has identified a substantial number of SAMA candidatessome involving major plant modificationsas potentially cost-beneficial. This further reflects the conservatisms inherent in the IPEC SAMA analysis and supports our conclusion that the analysis is reasonable under NEPA standards.

SUMMARY

FINDINGS OF FACT AND CONCLUSIONS OF LAW 242. Based upon a review of the entire record of this proceeding and the parties proposed findings of fact and conclusions of law, and based upon the findings set forth above, which are supported by reliable, probative, and substantive evidence in the record, the Board has decided all matters in controversy in NYS-12C in favor of Entergy and the NRC Staff.

243. Regarding the Staffs obligations under NEPA, the Board finds that the NRC Staff has independently reviewed Entergys SAMA analysis, including Entergys economic inputs to the MACCS2 code. The Board concludes that the Staff is justified in relying upon Entergys data, modeling assumptions, and SAMA analysis results in meeting its obligation under NEPA to provide a reasonably complete discussion of possible mitigation measures.704 244. The Board also concludes that the NRC Staff has provided a reasoned evaluation of whether and to what extent the issues raised in NYS-12C credibly could or would alter the Entergys SAMA analysis conclusions on which SAMAs are cost-beneficial to implement.705 With respect to New Yorks challenge to Entergys MACCS2 economic and decontamination cost inputs, we find that the overwhelming preponderance of the evidence demonstrates:

245. Entergys SAMA analysis is principally based on plant-, site-, and region-specific data. Entergys use of certain standardized economic and decontamination cost inputs found in MACCS2 Sample Problem A is not arbitrary or unreasonable. The challenged inputs are derived from the NRCs landmark NUREG-1150 study and have been subject to extensive peer reviews.

The NUREG-1150 values thus have a well-established technical pedigree that is widely recognized and accepted by the PRA community and continue to be used in licensee PRA and 704 Robertson, 490 U.S. at 352.

705 Pilgrim, CLI-10-22, 72 NRC at 208.

123

SAMA analyses and state-of-the-art NRC severe accident analyses. Accordingly, use of the values in the IPEC SAMA analysis is reasonable under NEPA standards.

246. There is no technical justification for New Yorks claim that the IPEC SAMA analysis assumed unrealistically large radionuclide particles and that accounting for smaller particle sizes would have resulted in greater cleanup costs. To the contrary, the record evidence shows that Entergy used a conservative deposition velocity value that results in greater modeled deposition, and thus, higher assumed cleanup costs within the 50-mile radius SAMA analysis region.

247. The nonfarm decontamination cost (CDNFRM) inputs used in the IPEC SAMA analysis are reasonable for the IPEC region because they are based on levels of contamination and population rather than upon the region in which the contamination occurs. By applying the CDNFRM values on a per-person basis, MACCS2 accounts for the region-specific population, including the high population density of New York City and its correspondingly higher building density. These values are consistent with the NUREG-1150 values and have been applied in Level 3-type PRA analyses (including SAMA analyses and the SOARCA project) for many years.

248. The two decontamination factors (DF = 3 and DF = 15) and the associated decontamination time (TIMDEC) values (60 and 120 days) used in the IPEC SAMA analysis are reasonable for use in a SAMA analysis because they are, by design, average values intended to reflect the full spectrum of severe accident scenarios examined in a SAMA analysis. They also reflect the objective, as integral to the MACCS2 code logic, of restoring areas to habitability quickly and cost-effectively through a staged implementation of offsite population protective measures, including decontamination in post-accident situations. The challenged TIMDEC 124

values also are consistent with the NUREG-1150 values and have been applied in Level-3 PRA analyses (including SAMA analyses and the SOARCA project) for many years.

249. New York has not provided alternative nonfarm decontamination cost and decontamination values that are more appropriate than those used in the IPEC SAMA analysis.

Dr. Lemays proposed values for the CDNFRM and TIMDEC variables, as reflected in ISR Approaches A-D, are inappropriate because they are derived from cost data that have no applicability to a nuclear power plant SAMA analysis, are based on selective and incorrect use of the data, and lack adequate technical justification. Moreover, because New Yorks proposed values generally exceed the maximum values allowed by MACCS2, their use in a SAMA analysis would require modification of the NRC-recommended MACCS2 source code, and as such, is an inappropriate, unauthorized software quality assurance practice for a licensee. Thus, the Board finds that New Yorks values are not reasonable for use in a SAMA analysis.

250. We find that the contested decontamination-related inputs to the IPEC SAMA analysis are reasonable and appropriate, and that New York has not provided any basis to conclude that there are additional potentially cost-beneficial SAMAs, particularly in view of the numerous demonstrated conservatisms in the IPEC SAMA analysis. Accordingly, we conclude that the modeling and data used in the IPEC SAMA analysis are reasonable and adequate for use by the NRC in satisfaction of its obligations under NEPA. Issues, motions, and arguments presented by the parties but not addressed herein have been found to be without merit, unnecessary, or not relevant to the Boards findings on NYS-12C.

VI. ORDER WHEREFORE, IT IS ORDERED, pursuant to 10 C.F.R. §§ 2.1210 and 51.104(a)(3), that the Consolidated Contention NYS-12C is resolved on the merits in favor of the NRC Staff and Entergy.

IT IS FURTHER ORDERED, this Partial Initial Decision will constitute a final decision of the Commission forty (40) days from the date of issuance (or the first agency business day following that date if it is a Saturday, Sunday, or federal holiday, see 10 C.F.R. § 2.306(a)),

unless a petition for review is filed in accordance with 10 C.F.R. § 2.1212, or the Commission directs otherwise.

IT IS FURTHER ORDERED that any party wishing to file a petition for review on the grounds specified in 10 C.F.R. § 2.341(b)(1) must do so within twenty-five (25) days after service of this Partial Initial Decision. The filing of a petition for review is mandatory for a party to have exhausted its administrative remedies before seeking judicial review. Within twenty-five (25) days after service of a petition for review, parties to the proceeding may file an answer supporting or opposing Commission review. Any petition for review and any answer shall conform to the requirements of 10 C.F.R. § 2.341(b)(2)-(3).

Although this ruling resolves all matters before the Board in connection with Consolidated Contention NYS-12C, NRC Staff issuance of the renewed operating licenses under 10 C.F.R. Part 54 must abide, among other things, the resolution of the remaining admitted contentions, including those contentions designated for future hearings.
