-247-LR & 50-286-LR Pre-filed Supplemental Testimony of Dr. Joram Hopenfeld In support of NYS-38/RK-TC-5 3 documents identified and provided by Entergy as relevant to Contention NYS

-38/RK-TC-5 that 1 were disclosed after the my initial submissions, NRC and Entergy correspondence, additional 2 NUREG reports, the SSER2, and additional scientific and scholarly reports, books, and articles.

3 I have used all these documents to inform me of the relevant facts and derive my conclusions.

4 5 Q. Have you prepared an assessment relating to the additional analyses conducted by 6 Entergy described above?

7 A. Yes, I have prepared a report related to Entergy's screening and refined fatigue analyses, 8 and the ongoing inadequacy of Entergy's aging management program; this report has been 9 marked and provided as Exhibit RIV000144, and reflects my analysis and opinions.

10 11 I relied on various documents in forming the opinions and conclusions in my report. Numerous 12 documents I have reviewed and relied upon in forming my opinions have been previously 13 submitted in this proceeding, and where discussed, are identified by their exhibit designations. I 14 have also relied on additional documents in forming my opinions; these documents have been 15 provided as Exhibits RIV000145 to RIV000 160, or by New York State as NYS000490, 16 NYS000507, NYS000510, and NYS000511. To the best of my knowledge, these are all true and 17 accurate copies of each document that I used and/or relied upon in preparing this testimony.

18 19 Q. Please describe how your supplemental report and analysis (RIV000144) relate to 20 your initial testimonies on Contention NYS-38/RK-TC-5. 21 A. My initial testimonies on Contention NYS

-38/RK-TC-5 related to Entergy's failure to 22 demonstrate that metal fatigue of reactor components will be adequately managed during the 23 proposed periods of extended operation at the plant as required by 10 C.F.R. § 54.21(c). In 24 particular, my testimony criticized Entergy's failure to expand the scope of its fatigue analysis, 25 and discussed Entergy's then

-vague and inadequate commitment (regulatory Commitment 43) to 26 determine the most limiting locations for Indian Point Unit 2 (IP2) and Indian Point Unit 3 (IP3) 27 and to conduct environmentally corrected fatigue analyses for any such locations.

7 My 28 testimony described what an analysis to determine the most limiting locations should entail, and 29 7 See Prefiled Written Testimony of Dr. Joram Hopenfeld Regarding NYS

-38/RK-TC-5 (June 19, 2012)

-247-LR & 50-286-LR Pre-filed Supplemental Testimony of Dr. Joram Hopenfeld In support of NYS-38/RK-TC-5 4 I provided a list of components to be evaluated to determine whether they are the most limiting.

-up refined fatigue analys es.9 My report, RIV000144, assesses the adequacy of 4 those analyses and thereby builds upon and updates my previous testimony related to whether 5 Entergy has appropriately expanded the scope of its fatigue analysis for Indian Point.

6 7 Q. What are your opinions on Entergy's additional fatigue evaluations

, with respect to 8 Entergy's Commitment 43 to determine the most limiting locations and conduct refined 9 analysis for any such locations?

10 A. In my supporting report, RIV000144, I conducted an extensive assessment of Entergy's 11 screening and refined fatigue evaluations. In brief summary, these analyses conducted on behalf 12 of Entergy for Indian Point were flawed in various respects. In particular, and as detailed in my 13 report, the screening and subsequent refined fatigue evaluations (1) failed to adequately consider 14 the impact of dissolved oxygen on fatigue life;10 (2) failed to consider synergistic aging effects 15 of radiation, thermal embrittlement, and stress corrosion cracking on fatigue life

11 and (3) 16 improperly relied on CUF values of record without adequately accounting for changes in 17 geometry, surface finish, heat transfer, strain rate, and radiation.12 Based on such a flawed 18 analysis, Entergy's efforts to expand the scope of its fatigue assessment was inadequate and 19 incomplete, and Entergy has continued to fail to conduct an appropriately expanded, bounding 20 analysis of the most limiting locations at Indian Point.13 Various components that are subject to 21 and may succumb to metal fatigue during the proposed periods of extended operation for Indian 22 8 Id. at 12-15. 9 Westinghouse, Indian Point Unit 2 and Unit 2 EAF Screening Evaluations, Calculation Note Number CN

What conclusions have you drawn related to Entergy's additional fatigue 6 evaluations, with respect to Entergy's Commitment 43 to determine the most limiting 7 locations and conduct refined analysis for any such locations?

8 A. As discussed in my report, based on my review of Entergy's screening and refined 9 fatigue analyses, Entergy has failed to adequately determine the most limiting locations for 10 Indian Point and to conduct the necessary expanded fatigue analysis for the plants.16 Also as I 11 discuss in my report, this failure represents a significant safety risk at Indian Point.17 It, thus, 12 remains my conclusion that Entergy has failed to demonstrate that metal fatigue will be 13 adequately managed at Indian Point during the proposed periods of extended operation.18 14 15 Q. Have the opinions and conclusions you submitted in your earlier testimonies related 16 to Contention NYS

-38/RK-TC-5 changed as a result of Entergy's additional fatigue 17 evaluations?

18 A. No, they have not. The analysis, opinions, and conclusions I discussed in my earlier 19 written testimonies remain valid and applicable, as Entergy has continued to fail to conduct an 20 appropriate expanded fatigue analysis.

-38/RK-TC-5 that were admitted by the ASLB on 2 March 31, 2015.19 3 A. The amended bases of Contention NYS

-38/RK-TC-5 that were advanced by the ASLB, 4 and for which I submitted an expert declaration, relate to Entergy's aging management plan for 5 RVI components. In particular, as memorialized in the SSER2, subsequent to the submission of 6 my earlier testimonies related to Contention NYS

-38/RK-TC-5, Entergy expressed its intention 7 to rely on its Fatigue Monitoring Program (FMP) to manage the effects of fatigue on RVI 8 components at Indian Point during the period s of extended operation; in order to account for the 9 effects of the reactor coolant environment on the fatigue of RVI components as required under 10 the ASME Code Section III, Subsections NG

-2160 and NG

-3121, Entergy committed, in 11 regulatory Commitment 49, to recalculating CUF values for RVI components to include reactor 12 coolant environmental effects.20 The supplemental bases of Contention NYS

-38/RK-TC-5 that 13 were admitted into this proceeding contended, among other things, that Entergy's commitment to 14 recalculate the CUF values of RVI components to include reactor coolant environment effects 15 involved a flawed methodology that failed to accurately and fully account for environmental 16 effects, and, thus, assure that fatigue of such components will be adequately managed during the 17 period of extended operation.21 Entergy has conducted such fatigue evaluations for RVI 18 components,22 and my report, Exhibit RIV000144, assesses the adequacy of those analyses.

19 20 Q. What are your opinions on Entergy's fatigue evaluations for RVI components, with 21 respect to Entergy's Commitment 49? 22 A. In my supporting report, Exhibit RIV000144, I conducted an extensive assessment of 23 Entergy's fatigue evaluations related to RVI components.

24 and (3) 3 improperly relied on CUF values of record without adequately accounting for changes in 4 geometry, surface finish, heat transfer, strain rate, and radiation.25 Based on such a flawed 5 analysis, Entergy's evaluations related to RVI components are inaccurate and fail to demonstrate 6 that such components will not exhaust their fatigue life

-CUFen >1.0-sometime during the 7 proposed extended periods of operation.26 Importantly, as I discuss in my report, Entergy's 8 flawed analysis represents a significant safety risk at Indian Point.27 9 10 Q. What conclusions have you drawn related to Entergy's fatigue evaluations for RVI 11 components

? 12 A. As discussed in my report, based on my review of Entergy's additional fatigue analyses 13 related to RVI components, it is my professional opinion that Entergy has failed to demonstrate 14 that the effects of metal fatigue on RVI components will be adequately managed at the Indian 15 Point facilities during the proposed period of extended operation

.28 16 17 Q. Do you have any additional comments on Entergy's Commitment 49 for managing 18 the effects of fatigue on RVI components during the proposed periods of extended 19 operations?

20 A. Yes. As I discussed in my supporting declaration to Riverkeeper and New York State's 21 amended contention, in Commitment 49 Entergy proposed (and NRC Staff agreed) that it need 22 not complete the calculation of CUFen values for IP3 RVI components until December 2015.29 23 The schedule for Entergy's resolution of this issue extends beyond the time frame for the 24 23 Supplemental Report of Dr. Joram Hopenfeld in Support of Contention NYS

That timeline likely will prevent 2 Riverkeeper from playing any meaningful role in their development or resolution. Entergy's 3 commitment to complete CUFen evaluations for RVI components in the future, without review 4 by the public, the ASLB, and/or NRC Staff, is unacceptable. By merely making a future 5 commitment, it is not possible to fully determine the adequacy of the calculated CUFen values 6 and Entergy's AMP for RVI components. An adequate analysis must be performed before a 7 determination is made about license renewal. NRC Staff's acceptance of Entergy's commitment 8 49 in the SSER2 to conduct environmentally corrected metal fatigue evaluations for RVI 9 components at some time in the future is not warranted or acceptable. By failing to undertake 10 and complete an adequate CUFen analysis now and not in the future, Entergy has failed to 11 demonstrate that metal fatigue of RVI components will be adequately managed during the PEO.

12 13 Furthermore, Entergy has not yet developed inspection acceptance criteria for baffle former bolts 14 in either IP2 or IP3.30 Instead, it has agreed to develop a technical justification including 15 acceptance criteria for baffle former bolts sometime prior to the first round of anticipated 16 inspections, which might not occur until 2019 for IP2 and 2021 for IP3 and would be after an 17 evidentiary hearing in this proceeding.31 The schedule for Entergy's resolution of this issue 18 extends beyond the time frame for the hearings in this ASLB proceeding and thus will not allow 19 for a testing of the adequacy of the proposed resolution of this issue in this proceeding. That 20 timeline likely will prevent Riverkeeper from playing any meaningful role in their development 21 or resolution.

10 A. In my supporting report, RIV000144, I conducted an extensive assessment of Entergy's 11 screening and refined fatigue evaluations. In brief summary, these analyses conducted on behalf 12 of Entergy for Indian Point were flawed in various respects. In particular, and as detailed in my 13 report, the screening and subsequent refined fatigue evaluations (1) failed to adequately consider 14 the impact of dissolved oxygen on fatigue life;10 (2) failed to consider synergistic aging effects 15 of radiation, thermal embrittlement, and stress corrosion cracking on fatigue life

11 and (3) 16 improperly relied on CUF values of record without adequately accounting for changes in 17 geometry, surface finish, heat transfer, strain rate, and radiation.12 Based on such a flawed 18 analysis, Entergy's efforts to expand the scope of its fatigue assessment was inadequate and 19 incomplete, and Entergy has continued to fail to conduct an appropriately expanded, bounding 20 analysis of the most limiting locations at Indian Point.13 Various components that are subject to 21 and may succumb to metal fatigue during the proposed periods of extended operation for Indian 22 8 Id. at 12-15. 9 Westinghouse, Indian Point Unit 2 and Unit 2 EAF Screening Evaluations, Calculation Note Number CN

What conclusions have you drawn related to Entergy's additional fatigue 6 evaluations, with respect to Entergy's Commitment 43 to determine the most limiting 7 locations and conduct refined analysis for any such locations?

8 A. As discussed in my report, based on my review of Entergy's screening and refined 9 fatigue analyses, Entergy has failed to adequately determine the most limiting locations for 10 Indian Point and to conduct the necessary expanded fatigue analysis for the plants.16 Also as I 11 discuss in my report, this failure represents a significant safety risk at Indian Point.17 It, thus, 12 remains my conclusion that Entergy has failed to demonstrate that metal fatigue will be 13 adequately managed at Indian Point during the proposed periods of extended operation.18 14 15 Q. Have the opinions and conclusions you submitted in your earlier testimonies related 16 to Contention NYS

18 A. No, they have not. The analysis, opinions, and conclusions I discussed in my earlier 19 written testimonies remain valid and applicable, as Entergy has continued to fail to conduct an 20 appropriate expanded fatigue analysis.

-38/RK-TC-5 that were advanced by the ASLB, 4 and for which I submitted an expert declaration, relate to Entergy's aging management plan for 5 RVI components. In particular, as memorialized in the SSER2, subsequent to the submission of 6 my earlier testimonies related to Contention NYS

-38/RK-TC-5, Entergy expressed its intention 7 to rely on its Fatigue Monitoring Program (FMP) to manage the effects of fatigue on RVI 8 components at Indian Point during the period s of extended operation; in order to account for the 9 effects of the reactor coolant environment on the fatigue of RVI components as required under 10 the ASME Code Section III, Subsections NG

-2160 and NG

-3121, Entergy committed, in 11 regulatory Commitment 49, to recalculating CUF values for RVI components to include reactor 12 coolant environmental effects.20 The supplemental bases of Contention NYS

-38/RK-TC-5 that 13 were admitted into this proceeding contended, among other things, that Entergy's commitment to 14 recalculate the CUF values of RVI components to include reactor coolant environment effects 15 involved a flawed methodology that failed to accurately and fully account for environmental 16 effects, and, thus, assure that fatigue of such components will be adequately managed during the 17 period of extended operation.21 Entergy has conducted such fatigue evaluations for RVI 18 components,22 and my report, Exhibit RIV000144, assesses the adequacy of those analyses.

19 20 Q. What are your opinions on Entergy's fatigue evaluations for RVI components, with 21 respect to Entergy's Commitment 49? 22 A. In my supporting report, Exhibit RIV000144, I conducted an extensive assessment of 23 Entergy's fatigue evaluations related to RVI components.

-247-LR & 50-286-LR Pre-filed Supplemental Testimony of Dr. Joram Hopenfeld In support of NYS-38/RK-TC-5 7 my expert report, these analyses conducted on behalf of Entergy for Indian Point were flawed in 1 various respects since they (1) failed to adequately consider the impact of dissolved oxygen on 2 fatigue life;23 (2) failed to consider the effects of radiation and stress corrosion

24 and (3) 3 improperly relied on CUF values of record without adequately accounting for changes in 4 geometry, surface finish, heat transfer, strain rate, and radiation.25 Based on such a flawed 5 analysis, Entergy's evaluations related to RVI components are inaccurate and fail to demonstrate 6 that such components will not exhaust their fatigue life

-CUFen >1.0-sometime during the 7 proposed extended periods of operation.26 Importantly, as I discuss in my report, Entergy's 8 flawed analysis represents a significant safety risk at Indian Point.27 9 10 Q. What conclusions have you drawn related to Entergy's fatigue evaluations for RVI 11 components

? 12 A. As discussed in my report, based on my review of Entergy's additional fatigue analyses 13 related to RVI components, it is my professional opinion that Entergy has failed to demonstrate 14 that the effects of metal fatigue on RVI components will be adequately managed at the Indian 15 Point facilities during the proposed period of extended operation

.28 16 17 Q. Do you have any additional comments on Entergy's Commitment 49 for managing 18 the effects of fatigue on RVI components during the proposed periods of extended 19 operations?

20 A. Yes. As I discussed in my supporting declaration to Riverkeeper and New York State's 21 amended contention, in Commitment 49 Entergy proposed (and NRC Staff agreed) that it need 22 not complete the calculation of CUFen values for IP3 RVI components until December 2015.29 23 The schedule for Entergy's resolution of this issue extends beyond the time frame for the 24 23 Supplemental Report of Dr. Joram Hopenfeld in Support of Contention NYS

That timeline likely will prevent 2 Riverkeeper from playing any meaningful role in their development or resolution. Entergy's 3 commitment to complete CUFen evaluations for RVI components in the future, without review 4 by the public, the ASLB, and/or NRC Staff, is unacceptable. By merely making a future 5 commitment, it is not possible to fully determine the adequacy of the calculated CUFen values 6 and Entergy's AMP for RVI components. An adequate analysis must be performed before a 7 determination is made about license renewal. NRC Staff's acceptance of Entergy's commitment 8 49 in the SSER2 to conduct environmentally corrected metal fatigue evaluations for RVI 9 components at some time in the future is not warranted or acceptable. By failing to undertake 10 and complete an adequate CUFen analysis now and not in the future, Entergy has failed to 11 demonstrate that metal fatigue of RVI components will be adequately managed during the PEO.

12 13 Furthermore, Entergy has not yet developed inspection acceptance criteria for baffle former bolts 14 in either IP2 or IP3.30 Instead, it has agreed to develop a technical justification including 15 acceptance criteria for baffle former bolts sometime prior to the first round of anticipated 16 inspections, which might not occur until 2019 for IP2 and 2021 for IP3 and would be after an 17 evidentiary hearing in this proceeding.31 The schedule for Entergy's resolution of this issue 18 extends beyond the time frame for the hearings in this ASLB proceeding and thus will not allow 19 for a testing of the adequacy of the proposed resolution of this issue in this proceeding. That 20 timeline likely will prevent Riverkeeper from playing any meaningful role in their development 21 or resolution.
