Docket Nos. 50-247-LR & 50-286-LR Pre-filed Supplemental Testimony of Dr. Joram Hopenfeld In support of NYS-38/RK-TC-5 1 testimonies in 2012, Entergy has undertaken certain additional analyses that are relevant to the 2 issues raised in Contention NYS-38/RK-TC-5. In addition, Riverkeeper and New York State 3 successfully raised additional bases to Contention NYS-38/RK-TC-5 after the issuance of 4 Supplement 2 to NUREG-1930, Safety Evaluation Report Related to the License Renewal of 5 Indian Point Generating Unit Nos. 2 and 3 (Exhibit NYS000507) (SSER2) in November 6 2014. 4 The purpose of this supplemental testimony is to respond to Entergys further analyses 7 and provide support for the recently admitted additional contention bases. | |||
8 9 Q. Please describe your understanding of what additional analyses Entergy undertook 10 after you submitted your prefiled direct and rebuttal testimonies related to Contention 11 NYS-38/RK-TC-5 in this proceeding. | |||
12 A. In connection with Entergys regulatory Commitment 43, Entergys vendor 13 Westinghouse conducted a screening analysis aimed to allegedly determine the most limiting 14 locations for fatigue evaluation purposes, as well as subsequent refined fatigue evaluations. 5 In 15 addition, in connection with Entergys regulatory Commitment 49, the approval of which was 16 memorialized in the SSER2, Westinghouse conducted fatigue analyses related to reactor vessel 17 internal (RVI) components. 6 18 19 Q. Have you reviewed these additional analyses? | |||
20 A. Yes. | |||
21 22 Q. Have you reviewed anything else in connection with this supplemental testimony? | |||
23 A. Yes. In addition to the many documents I previously reviewed as described in my initial 24 and rebuttal testimonies related to Contention NYS-38/RK-TC-5, I have reviewed dozens of 4 | |||

8 A. Yes, I have prepared a report related to Entergys screening and refined fatigue analyses, 9 and the ongoing inadequacy of Entergys aging management program; this report has been 10 marked and provided as Exhibit RIV000144, and reflects my analysis and opinions. | |||
11 12 I relied on various documents in forming the opinions and conclusions in my report. Numerous 13 documents I have reviewed and relied upon in forming my opinions have been previously 14 submitted in this proceeding, and where discussed, are identified by their exhibit designations. I 15 have also relied on additional documents in forming my opinions; these documents have been 16 provided as Exhibits RIV000145 to RIV000160, or by New York State as NYS000490, 17 NYS000507, NYS000510, and NYS000511. To the best of my knowledge, these are all true and 18 accurate copies of each document that I used and/or relied upon in preparing this testimony. | |||
19 20 Q. Please describe how your supplemental report and analysis (RIV000144) relate to 21 your initial testimonies on Contention NYS-38/RK-TC-5. | |||
22 A. My initial testimonies on Contention NYS-38/RK-TC-5 related to Entergys failure to 23 demonstrate that metal fatigue of reactor components will be adequately managed during the 24 proposed periods of extended operation at the plant as required by 10 C.F.R. § 54.21(c). In 25 particular, my testimony criticized Entergys failure to expand the scope of its fatigue analysis, 26 and discussed Entergys then-vague and inadequate commitment (regulatory Commitment 43) to 27 determine the most limiting locations for Indian Point Unit 2 (IP2) and Indian Point Unit 3 (IP3) 28 and to conduct environmentally corrected fatigue analyses for any such locations. 7 My 29 testimony described what an analysis to determine the most limiting locations should entail, and 7 | |||

Docket Nos. 50 | Docket Nos. 50-247-LR & 50-286-LR Pre-filed Supplemental Testimony of Dr. Joram Hopenfeld In support of NYS-38/RK-TC-5 1 I provided a list of components to be evaluated to determine whether they are the most limiting. 8 2 After I submitted my earlier testimonies, Entergy did undertake a screening analysis in an 3 attempt to fulfill Commitment 43 and determine the most limiting locations at Indian Point, as 4 well as follow-up refined fatigue analyses. 9 My report, RIV000144, assesses the adequacy of 5 those analyses and thereby builds upon and updates my previous testimony related to whether 6 Entergy has appropriately expanded the scope of its fatigue analysis for Indian Point. | ||

11 A. In my supporting report, RIV000144, I conducted an extensive assessment of Entergys 12 screening and refined fatigue evaluations. In brief summary, these analyses conducted on behalf 13 of Entergy for Indian Point were flawed in various respects. In particular, and as detailed in my 14 report, the screening and subsequent refined fatigue evaluations (1) failed to adequately consider 15 the impact of dissolved oxygen on fatigue life; 10 (2) failed to consider synergistic aging effects 16 of radiation, thermal embrittlement, and stress corrosion cracking on fatigue life; 11 and (3) 17 improperly relied on CUF values of record without adequately accounting for changes in 18 geometry, surface finish, heat transfer, strain rate, and radiation. 12 Based on such a flawed 19 analysis, Entergys efforts to expand the scope of its fatigue assessment was inadequate and 20 incomplete, and Entergy has continued to fail to conduct an appropriately expanded, bounding 21 analysis of the most limiting locations at Indian Point. 13 Various components that are subject to 22 and may succumb to metal fatigue during the proposed periods of extended operation for Indian 8 | |||

6 Q. What conclusions have you drawn related to Entergys additional fatigue 7 evaluations, with respect to Entergys Commitment 43 to determine the most limiting 8 locations and conduct refined analysis for any such locations? | |||
9 A. As discussed in my report, based on my review of Entergys screening and refined 10 fatigue analyses, Entergy has failed to adequately determine the most limiting locations for 11 Indian Point and to conduct the necessary expanded fatigue analysis for the plants. 16 Also as I 12 discuss in my report, this failure represents a significant safety risk at Indian Point.17 It, thus, 13 remains my conclusion that Entergy has failed to demonstrate that metal fatigue will be 14 adequately managed at Indian Point during the proposed periods of extended operation. 18 15 16 Q. Have the opinions and conclusions you submitted in your earlier testimonies related 17 to Contention NYS-38/RK-TC-5 changed as a result of Entergys additional fatigue 18 evaluations? | |||
19 A. No, they have not. The analysis, opinions, and conclusions I discussed in my earlier 20 written testimonies remain valid and applicable, as Entergy has continued to fail to conduct an 21 appropriate expanded fatigue analysis. | |||

Docket Nos. 50-247-LR & 50-286-LR Pre-filed Supplemental Testimony of Dr. Joram Hopenfeld In support of NYS-38/RK-TC-5 1 Q. Please describe how your supplemental report and analysis (RIV000144) relate to 2 the additional bases of Contention NYS-38/RK-TC-5 that were admitted by the ASLB on 3 March 31, 2015. 19 4 A. The amended bases of Contention NYS-38/RK-TC-5 that were advanced by the ASLB, 5 and for which I submitted an expert declaration, relate to Entergys aging management plan for 6 RVI components. In particular, as memorialized in the SSER2, subsequent to the submission of 7 my earlier testimonies related to Contention NYS-38/RK-TC-5, Entergy expressed its intention 8 to rely on its Fatigue Monitoring Program (FMP) to manage the effects of fatigue on RVI 9 components at Indian Point during the periods of extended operation; in order to account for the 10 effects of the reactor coolant environment on the fatigue of RVI components as required under 11 the ASME Code Section III, Subsections NG-2160 and NG-3121, Entergy committed, in 12 regulatory Commitment 49, to recalculating CUF values for RVI components to include reactor 13 coolant environmental effects. 20 The supplemental bases of Contention NYS-38/RK-TC-5 that 14 were admitted into this proceeding contended, among other things, that Entergys commitment to 15 recalculate the CUF values of RVI components to include reactor coolant environment effects 16 involved a flawed methodology that failed to accurately and fully account for environmental 17 effects, and, thus, assure that fatigue of such components will be adequately managed during the 18 period of extended operation. 21 Entergy has conducted such fatigue evaluations for RVI 19 components, 22 and my report, Exhibit RIV000144, assesses the adequacy of those analyses. | |||
20 21 Q. What are your opinions on Entergys fatigue evaluations for RVI components, with 22 respect to Entergys Commitment 49? | |||
23 A. In my supporting report, Exhibit RIV000144, I conducted an extensive assessment of 24 Entergys fatigue evaluations related to RVI components. As discussed above, and detailed in 19 In the Matter of Entergy Nuclear Operations, Inc. (Indian Point Nuclear Generating Units 2 and 3), Docket Nos. | |||

21 See Declaration of Dr. Joram Hopenfeld (February 12, 2015) at ¶¶ 10-18 (Exhibit RIV000148) 22 See Westinghouse, Indian Point Unit 2 (IP2) and Unit 3 (IP3) Refined EAF Analyses and EAF Screening Evaluations, Calculation Note Number CN, PAFM-13-32 (August 2013), IPECPROP00078338 (Exhibit NYS000511). | |||
6 | |||
Docket Nos. 50-247-LR & 50-286-LR Pre-filed Supplemental Testimony of Dr. Joram Hopenfeld In support of NYS-38/RK-TC-5 1 my expert report, these analyses conducted on behalf of Entergy for Indian Point were flawed in 2 various respects since they (1) failed to adequately consider the impact of dissolved oxygen on 3 fatigue life; 23 (2) failed to consider the effects of radiation and stress corrosion; 24 and (3) 4 improperly relied on CUF values of record without adequately accounting for changes in 5 geometry, surface finish, heat transfer, strain rate, and radiation. 25 Based on such a flawed 6 analysis, Entergys evaluations related to RVI components are inaccurate and fail to demonstrate 7 that such components will not exhaust their fatigue lifeCUFen >1.0sometime during the 8 proposed extended periods of operation. 26 Importantly, as I discuss in my report, Entergys 9 flawed analysis represents a significant safety risk at Indian Point. 27 10 11 Q. What conclusions have you drawn related to Entergys fatigue evaluations for RVI 12 components? | |||
13 A. As discussed in my report, based on my review of Entergys additional fatigue analyses 14 related to RVI components, it is my professional opinion that Entergy has failed to demonstrate 15 that the effects of metal fatigue on RVI components will be adequately managed at the Indian 16 Point facilities during the proposed period of extended operation. 28 17 18 Q. Do you have any additional comments on Entergys Commitment 49 for managing 19 the effects of fatigue on RVI components during the proposed periods of extended 20 operations? | |||
21 A. Yes. As I discussed in my supporting declaration to Riverkeeper and New York States 22 amended contention, in Commitment 49 Entergy proposed (and NRC Staff agreed) that it need 23 not complete the calculation of CUFen values for IP3 RVI components until December 2015. 29 24 The schedule for Entergys resolution of this issue extends beyond the time frame for the 23 Supplemental Report of Dr. Joram Hopenfeld in Support of Contention NYS-26/RK-TC-1B and Amended Contention NYS-38/RK-TC-5 (June 9, 2015), at § 2 (Exhibit RIV000144). | |||

Docket Nos. 50-247-LR & 50-286-LR Pre-filed Supplemental Testimony of Dr. Joram Hopenfeld In support of NYS-38/RK-TC-5 1 hearings in this ASLB proceeding and thus will not allow for a testing of the adequacy of the 2 proposed resolution of these issues in this proceeding. That timeline likely will prevent 3 Riverkeeper from playing any meaningful role in their development or resolution. Entergys 4 commitment to complete CUFen evaluations for RVI components in the future, without review 5 by the public, the ASLB, and/or NRC Staff, is unacceptable. By merely making a future 6 commitment, it is not possible to fully determine the adequacy of the calculated CUFen values 7 and Entergys AMP for RVI components. An adequate analysis must be performed before a 8 determination is made about license renewal. NRC Staffs acceptance of Entergys commitment 9 49 in the SSER2 to conduct environmentally corrected metal fatigue evaluations for RVI 10 components at some time in the future is not warranted or acceptable. By failing to undertake 11 and complete an adequate CUFen analysis now and not in the future, Entergy has failed to 12 demonstrate that metal fatigue of RVI components will be adequately managed during the PEO. | |||
13 14 Furthermore, Entergy has not yet developed inspection acceptance criteria for baffle former bolts 15 in either IP2 or IP3. 30 Instead, it has agreed to develop a technical justification including 16 acceptance criteria for baffle former bolts sometime prior to the first round of anticipated 17 inspections, which might not occur until 2019 for IP2 and 2021 for IP3 and would be after an 18 evidentiary hearing in this proceeding. 31 The schedule for Entergys resolution of this issue 19 extends beyond the time frame for the hearings in this ASLB proceeding and thus will not allow 20 for a testing of the adequacy of the proposed resolution of this issue in this proceeding. That 21 timeline likely will prevent Riverkeeper from playing any meaningful role in their development 22 or resolution. | |||

In connection with Entergys regulatory Commitment 43, Entergys vendor 13 Westinghouse conducted a screening analysis aimed to allegedly determine the most limiting 14 locations for fatigue evaluation purposes, as well as subsequent refined fatigue evaluations. 5 In 15 addition, in connection with Entergys regulatory Commitment 49, the approval of which was 16 memorialized in the SSER2, Westinghouse conducted fatigue analyses related to reactor vessel 17 internal (RVI) components. 6 18 19 Q. Have you reviewed these additional analyses? | |||
20 A. Yes. | |||
21 22 Q. Have you reviewed anything else in connection with this supplemental testimony? | |||
23 A. Yes. In addition to the many documents I previously reviewed as described in my initial 24 and rebuttal testimonies related to Contention NYS-38/RK-TC-5, I have reviewed dozens of 4 | |||

Docket Nos. 50-247-LR & 50-286-LR Pre-filed Supplemental Testimony of Dr. Joram Hopenfeld In support of NYS-38/RK-TC-5 1 documents identified and provided by Entergy as relevant to Contention NYS-38/RK-TC-5 that 2 were disclosed after the my initial submissions, NRC and Entergy correspondence, additional 3 NUREG reports, the SSER2, and additional scientific and scholarly reports, books, and articles. | |||
4 I have used all these documents to inform me of the relevant facts and derive my conclusions. | |||
5 6 Q. Have you prepared an assessment relating to the additional analyses conducted by 7 Entergy described above? | |||
8 A. Yes, I have prepared a report related to Entergys screening and refined fatigue analyses, 9 and the ongoing inadequacy of Entergys aging management program; this report has been 10 marked and provided as Exhibit RIV000144, and reflects my analysis and opinions. | |||
11 12 I relied on various documents in forming the opinions and conclusions in my report. Numerous 13 documents I have reviewed and relied upon in forming my opinions have been previously 14 submitted in this proceeding, and where discussed, are identified by their exhibit designations. I 15 have also relied on additional documents in forming my opinions; these documents have been 16 provided as Exhibits RIV000145 to RIV000160, or by New York State as NYS000490, 17 NYS000507, NYS000510, and NYS000511. To the best of my knowledge, these are all true and 18 accurate copies of each document that I used and/or relied upon in preparing this testimony. | |||
19 20 Q. Please describe how your supplemental report and analysis (RIV000144) relate to 21 your initial testimonies on Contention NYS-38/RK-TC-5. | |||
22 A. My initial testimonies on Contention NYS-38/RK-TC-5 related to Entergys failure to 23 demonstrate that metal fatigue of reactor components will be adequately managed during the 24 proposed periods of extended operation at the plant as required by 10 C.F.R. § 54.21(c). In 25 particular, my testimony criticized Entergys failure to expand the scope of its fatigue analysis, 26 and discussed Entergys then-vague and inadequate commitment (regulatory Commitment 43) to 27 determine the most limiting locations for Indian Point Unit 2 (IP2) and Indian Point Unit 3 (IP3) 28 and to conduct environmentally corrected fatigue analyses for any such locations. 7 My 29 testimony described what an analysis to determine the most limiting locations should entail, and 7 | |||

- | 11 A. In my supporting report, RIV000144, I conducted an extensive assessment of Entergys 12 screening and refined fatigue evaluations. In brief summary, these analyses conducted on behalf 13 of Entergy for Indian Point were flawed in various respects. In particular, and as detailed in my 14 report, the screening and subsequent refined fatigue evaluations (1) failed to adequately consider 15 the impact of dissolved oxygen on fatigue life; 10 (2) failed to consider synergistic aging effects 16 of radiation, thermal embrittlement, and stress corrosion cracking on fatigue life; 11 and (3) 17 improperly relied on CUF values of record without adequately accounting for changes in 18 geometry, surface finish, heat transfer, strain rate, and radiation. 12 Based on such a flawed 19 analysis, Entergys efforts to expand the scope of its fatigue assessment was inadequate and 20 incomplete, and Entergy has continued to fail to conduct an appropriately expanded, bounding 21 analysis of the most limiting locations at Indian Point. 13 Various components that are subject to 22 and may succumb to metal fatigue during the proposed periods of extended operation for Indian 8 | ||

6 Q. What conclusions have you drawn related to Entergys additional fatigue 7 evaluations, with respect to Entergys Commitment 43 to determine the most limiting 8 locations and conduct refined analysis for any such locations? | |||
9 A. As discussed in my report, based on my review of Entergys screening and refined 10 fatigue analyses, Entergy has failed to adequately determine the most limiting locations for 11 Indian Point and to conduct the necessary expanded fatigue analysis for the plants. 16 Also as I 12 discuss in my report, this failure represents a significant safety risk at Indian Point.17 It, thus, 13 remains my conclusion that Entergy has failed to demonstrate that metal fatigue will be 14 adequately managed at Indian Point during the proposed periods of extended operation. 18 15 16 Q. Have the opinions and conclusions you submitted in your earlier testimonies related 17 to Contention NYS-38/RK-TC-5 changed as a result of Entergys additional fatigue 18 evaluations? | |||
19 A. No, they have not. The analysis, opinions, and conclusions I discussed in my earlier 20 written testimonies remain valid and applicable, as Entergy has continued to fail to conduct an 21 appropriate expanded fatigue analysis. | |||

Please describe how your supplemental report and analysis (RIV000144) relate to 2 the additional bases of Contention NYS-38/RK-TC-5 that were admitted by the ASLB on 3 March 31, 2015. 19 4 A. The amended bases of Contention NYS-38/RK-TC-5 that were advanced by the ASLB, 5 and for which I submitted an expert declaration, relate to Entergys aging management plan for 6 RVI components. In particular, as memorialized in the SSER2, subsequent to the submission of 7 my earlier testimonies related to Contention NYS-38/RK-TC-5, Entergy expressed its intention 8 to rely on its Fatigue Monitoring Program (FMP) to manage the effects of fatigue on RVI 9 components at Indian Point during the periods of extended operation; in order to account for the 10 effects of the reactor coolant environment on the fatigue of RVI components as required under 11 the ASME Code Section III, Subsections NG-2160 and NG-3121, Entergy committed, in 12 regulatory Commitment 49, to recalculating CUF values for RVI components to include reactor 13 coolant environmental effects. 20 The supplemental bases of Contention NYS-38/RK-TC-5 that 14 were admitted into this proceeding contended, among other things, that Entergys commitment to 15 recalculate the CUF values of RVI components to include reactor coolant environment effects 16 involved a flawed methodology that failed to accurately and fully account for environmental 17 effects, and, thus, assure that fatigue of such components will be adequately managed during the 18 period of extended operation. 21 Entergy has conducted such fatigue evaluations for RVI 19 components, 22 and my report, Exhibit RIV000144, assesses the adequacy of those analyses. | ||

Yes. As I discussed in my supporting declaration to Riverkeeper and New York States 22 amended contention, in Commitment 49 Entergy proposed (and NRC Staff agreed) that it need 23 not complete the calculation of CUFen values for IP3 RVI components until December 2015. 29 24 The schedule for Entergys resolution of this issue extends beyond the time frame for the 23 Supplemental Report of Dr. Joram Hopenfeld in Support of Contention NYS-26/RK-TC-1B and Amended Contention NYS-38/RK-TC-5 (June 9, 2015), at § 2 (Exhibit RIV000144). | ||

That timeline likely will prevent 3 Riverkeeper from playing any meaningful role in their development or resolution. Entergys 4 commitment to complete CUFen evaluations for RVI components in the future, without review 5 by the public, the ASLB, and/or NRC Staff, is unacceptable. By merely making a future 6 commitment, it is not possible to fully determine the adequacy of the calculated CUFen values 7 and Entergys AMP for RVI components. An adequate analysis must be performed before a 8 determination is made about license renewal. NRC Staffs acceptance of Entergys commitment 9 49 in the SSER2 to conduct environmentally corrected metal fatigue evaluations for RVI 10 components at some time in the future is not warranted or acceptable. By failing to undertake 11 and complete an adequate CUFen analysis now and not in the future, Entergy has failed to 12 demonstrate that metal fatigue of RVI components will be adequately managed during the PEO. | ||
13 14 Furthermore, Entergy has not yet developed inspection acceptance criteria for baffle former bolts 15 in either IP2 or IP3. 30 Instead, it has agreed to develop a technical justification including 16 acceptance criteria for baffle former bolts sometime prior to the first round of anticipated 17 inspections, which might not occur until 2019 for IP2 and 2021 for IP3 and would be after an 18 evidentiary hearing in this proceeding. 31 The schedule for Entergys resolution of this issue 19 extends beyond the time frame for the hearings in this ASLB proceeding and thus will not allow 20 for a testing of the adequacy of the proposed resolution of this issue in this proceeding.

4 I have used all these documents to inform me of the relevant facts and derive my conclusions.
5 6 Q. Have you prepared an assessment relating to the additional analyses conducted by 7 Entergy described above?
8 A. Yes, I have prepared a report related to Entergys screening and refined fatigue analyses, 9 and the ongoing inadequacy of Entergys aging management program; this report has been 10 marked and provided as Exhibit RIV000144, and reflects my analysis and opinions.
11 12 I relied on various documents in forming the opinions and conclusions in my report. Numerous 13 documents I have reviewed and relied upon in forming my opinions have been previously 14 submitted in this proceeding, and where discussed, are identified by their exhibit designations. I 15 have also relied on additional documents in forming my opinions; these documents have been 16 provided as Exhibits RIV000145 to RIV000160, or by New York State as NYS000490, 17 NYS000507, NYS000510, and NYS000511. To the best of my knowledge, these are all true and 18 accurate copies of each document that I used and/or relied upon in preparing this testimony.
19 20 Q. Please describe how your supplemental report and analysis (RIV000144) relate to 21 your initial testimonies on Contention NYS-38/RK-TC-5.
22 A. My initial testimonies on Contention NYS-38/RK-TC-5 related to Entergys failure to 23 demonstrate that metal fatigue of reactor components will be adequately managed during the 24 proposed periods of extended operation at the plant as required by 10 C.F.R. § 54.21(c). In 25 particular, my testimony criticized Entergys failure to expand the scope of its fatigue analysis, 26 and discussed Entergys then-vague and inadequate commitment (regulatory Commitment 43) to 27 determine the most limiting locations for Indian Point Unit 2 (IP2) and Indian Point Unit 3 (IP3) 28 and to conduct environmentally corrected fatigue analyses for any such locations. 7 My 29 testimony described what an analysis to determine the most limiting locations should entail, and 7

Docket Nos. 50-247-LR & 50-286-LR Pre-filed Supplemental Testimony of Dr. Joram Hopenfeld In support of NYS-38/RK-TC-5 1 I provided a list of components to be evaluated to determine whether they are the most limiting. 8 2 After I submitted my earlier testimonies, Entergy did undertake a screening analysis in an 3 attempt to fulfill Commitment 43 and determine the most limiting locations at Indian Point, as 4 well as follow-up refined fatigue analyses. 9 My report, RIV000144, assesses the adequacy of 5 those analyses and thereby builds upon and updates my previous testimony related to whether 6 Entergy has appropriately expanded the scope of its fatigue analysis for Indian Point.
7 8 Q. What are your opinions on Entergys additional fatigue evaluations, with respect to 9 Entergys Commitment 43 to determine the most limiting locations and conduct refined 10 analysis for any such locations?
11 A. In my supporting report, RIV000144, I conducted an extensive assessment of Entergys 12 screening and refined fatigue evaluations. In brief summary, these analyses conducted on behalf 13 of Entergy for Indian Point were flawed in various respects. In particular, and as detailed in my 14 report, the screening and subsequent refined fatigue evaluations (1) failed to adequately consider 15 the impact of dissolved oxygen on fatigue life; 10 (2) failed to consider synergistic aging effects 16 of radiation, thermal embrittlement, and stress corrosion cracking on fatigue life; 11 and (3) 17 improperly relied on CUF values of record without adequately accounting for changes in 18 geometry, surface finish, heat transfer, strain rate, and radiation. 12 Based on such a flawed 19 analysis, Entergys efforts to expand the scope of its fatigue assessment was inadequate and 20 incomplete, and Entergy has continued to fail to conduct an appropriately expanded, bounding 21 analysis of the most limiting locations at Indian Point. 13 Various components that are subject to 22 and may succumb to metal fatigue during the proposed periods of extended operation for Indian 8

6 Q. What conclusions have you drawn related to Entergys additional fatigue 7 evaluations, with respect to Entergys Commitment 43 to determine the most limiting 8 locations and conduct refined analysis for any such locations?
9 A. As discussed in my report, based on my review of Entergys screening and refined 10 fatigue analyses, Entergy has failed to adequately determine the most limiting locations for 11 Indian Point and to conduct the necessary expanded fatigue analysis for the plants. 16 Also as I 12 discuss in my report, this failure represents a significant safety risk at Indian Point.17 It, thus, 13 remains my conclusion that Entergy has failed to demonstrate that metal fatigue will be 14 adequately managed at Indian Point during the proposed periods of extended operation. 18 15 16 Q. Have the opinions and conclusions you submitted in your earlier testimonies related 17 to Contention NYS-38/RK-TC-5 changed as a result of Entergys additional fatigue 18 evaluations?
19 A. No, they have not. The analysis, opinions, and conclusions I discussed in my earlier 20 written testimonies remain valid and applicable, as Entergy has continued to fail to conduct an 21 appropriate expanded fatigue analysis.

Docket Nos. 50-247-LR & 50-286-LR Pre-filed Supplemental Testimony of Dr. Joram Hopenfeld In support of NYS-38/RK-TC-5 1 Q. Please describe how your supplemental report and analysis (RIV000144) relate to 2 the additional bases of Contention NYS-38/RK-TC-5 that were admitted by the ASLB on 3 March 31, 2015. 19 4 A. The amended bases of Contention NYS-38/RK-TC-5 that were advanced by the ASLB, 5 and for which I submitted an expert declaration, relate to Entergys aging management plan for 6 RVI components. In particular, as memorialized in the SSER2, subsequent to the submission of 7 my earlier testimonies related to Contention NYS-38/RK-TC-5, Entergy expressed its intention 8 to rely on its Fatigue Monitoring Program (FMP) to manage the effects of fatigue on RVI 9 components at Indian Point during the periods of extended operation; in order to account for the 10 effects of the reactor coolant environment on the fatigue of RVI components as required under 11 the ASME Code Section III, Subsections NG-2160 and NG-3121, Entergy committed, in 12 regulatory Commitment 49, to recalculating CUF values for RVI components to include reactor 13 coolant environmental effects. 20 The supplemental bases of Contention NYS-38/RK-TC-5 that 14 were admitted into this proceeding contended, among other things, that Entergys commitment to 15 recalculate the CUF values of RVI components to include reactor coolant environment effects 16 involved a flawed methodology that failed to accurately and fully account for environmental 17 effects, and, thus, assure that fatigue of such components will be adequately managed during the 18 period of extended operation. 21 Entergy has conducted such fatigue evaluations for RVI 19 components, 22 and my report, Exhibit RIV000144, assesses the adequacy of those analyses.
20 21 Q. What are your opinions on Entergys fatigue evaluations for RVI components, with 22 respect to Entergys Commitment 49?
23 A. In my supporting report, Exhibit RIV000144, I conducted an extensive assessment of 24 Entergys fatigue evaluations related to RVI components. As discussed above, and detailed in 19 In the Matter of Entergy Nuclear Operations, Inc. (Indian Point Nuclear Generating Units 2 and 3), Docket Nos.

Docket Nos. 50-247-LR & 50-286-LR Pre-filed Supplemental Testimony of Dr. Joram Hopenfeld In support of NYS-38/RK-TC-5 1 my expert report, these analyses conducted on behalf of Entergy for Indian Point were flawed in 2 various respects since they (1) failed to adequately consider the impact of dissolved oxygen on 3 fatigue life; 23 (2) failed to consider the effects of radiation and stress corrosion; 24 and (3) 4 improperly relied on CUF values of record without adequately accounting for changes in 5 geometry, surface finish, heat transfer, strain rate, and radiation. 25 Based on such a flawed 6 analysis, Entergys evaluations related to RVI components are inaccurate and fail to demonstrate 7 that such components will not exhaust their fatigue lifeCUFen >1.0sometime during the 8 proposed extended periods of operation. 26 Importantly, as I discuss in my report, Entergys 9 flawed analysis represents a significant safety risk at Indian Point. 27 10 11 Q. What conclusions have you drawn related to Entergys fatigue evaluations for RVI 12 components?
13 A. As discussed in my report, based on my review of Entergys additional fatigue analyses 14 related to RVI components, it is my professional opinion that Entergy has failed to demonstrate 15 that the effects of metal fatigue on RVI components will be adequately managed at the Indian 16 Point facilities during the proposed period of extended operation. 28 17 18 Q. Do you have any additional comments on Entergys Commitment 49 for managing 19 the effects of fatigue on RVI components during the proposed periods of extended 20 operations?
21 A. Yes. As I discussed in my supporting declaration to Riverkeeper and New York States 22 amended contention, in Commitment 49 Entergy proposed (and NRC Staff agreed) that it need 23 not complete the calculation of CUFen values for IP3 RVI components until December 2015. 29 24 The schedule for Entergys resolution of this issue extends beyond the time frame for the 23 Supplemental Report of Dr. Joram Hopenfeld in Support of Contention NYS-26/RK-TC-1B and Amended Contention NYS-38/RK-TC-5 (June 9, 2015), at § 2 (Exhibit RIV000144).

Docket Nos. 50-247-LR & 50-286-LR Pre-filed Supplemental Testimony of Dr. Joram Hopenfeld In support of NYS-38/RK-TC-5 1 hearings in this ASLB proceeding and thus will not allow for a testing of the adequacy of the 2 proposed resolution of these issues in this proceeding. That timeline likely will prevent 3 Riverkeeper from playing any meaningful role in their development or resolution. Entergys 4 commitment to complete CUFen evaluations for RVI components in the future, without review 5 by the public, the ASLB, and/or NRC Staff, is unacceptable. By merely making a future 6 commitment, it is not possible to fully determine the adequacy of the calculated CUFen values 7 and Entergys AMP for RVI components. An adequate analysis must be performed before a 8 determination is made about license renewal. NRC Staffs acceptance of Entergys commitment 9 49 in the SSER2 to conduct environmentally corrected metal fatigue evaluations for RVI 10 components at some time in the future is not warranted or acceptable. By failing to undertake 11 and complete an adequate CUFen analysis now and not in the future, Entergy has failed to 12 demonstrate that metal fatigue of RVI components will be adequately managed during the PEO.
13 14 Furthermore, Entergy has not yet developed inspection acceptance criteria for baffle former bolts 15 in either IP2 or IP3. 30 Instead, it has agreed to develop a technical justification including 16 acceptance criteria for baffle former bolts sometime prior to the first round of anticipated 17 inspections, which might not occur until 2019 for IP2 and 2021 for IP3 and would be after an 18 evidentiary hearing in this proceeding. 31 The schedule for Entergys resolution of this issue 19 extends beyond the time frame for the hearings in this ASLB proceeding and thus will not allow 20 for a testing of the adequacy of the proposed resolution of this issue in this proceeding. That 21 timeline likely will prevent Riverkeeper from playing any meaningful role in their development 22 or resolution.

Docket Nos. 50-247-LR & 50-286-LR Pre-filed Supplemental Testimony of Dr. Joram Hopenfeld In support of NYS-38/RK-TC-5 1 testimonies in 2012, Entergy has undertaken certain additional analyses that are relevant to the 2 issues raised in Contention NYS-38/RK-TC-5. In addition, Riverkeeper and New York State 3 successfully raised additional bases to Contention NYS-38/RK-TC-5 after the issuance of 4 Supplement 2 to NUREG-1930, Safety Evaluation Report Related to the License Renewal of 5 Indian Point Generating Unit Nos. 2 and 3 (Exhibit NYS000507) (SSER2) in November 6 2014. 4 The purpose of this supplemental testimony is to respond to Entergys further analyses 7 and provide support for the recently admitted additional contention bases.
8 9 Q. Please describe your understanding of what additional analyses Entergy undertook 10 after you submitted your prefiled direct and rebuttal testimonies related to Contention 11 NYS-38/RK-TC-5 in this proceeding.
12 A. In connection with Entergys regulatory Commitment 43, Entergys vendor 13 Westinghouse conducted a screening analysis aimed to allegedly determine the most limiting 14 locations for fatigue evaluation purposes, as well as subsequent refined fatigue evaluations. 5 In 15 addition, in connection with Entergys regulatory Commitment 49, the approval of which was 16 memorialized in the SSER2, Westinghouse conducted fatigue analyses related to reactor vessel 17 internal (RVI) components. 6 18 19 Q. Have you reviewed these additional analyses?
20 A. Yes.
21 22 Q. Have you reviewed anything else in connection with this supplemental testimony?
23 A. Yes. In addition to the many documents I previously reviewed as described in my initial 24 and rebuttal testimonies related to Contention NYS-38/RK-TC-5, I have reviewed dozens of 4

4 I have used all these documents to inform me of the relevant facts and derive my conclusions.
5 6 Q. Have you prepared an assessment relating to the additional analyses conducted by 7 Entergy described above?
8 A. Yes, I have prepared a report related to Entergys screening and refined fatigue analyses, 9 and the ongoing inadequacy of Entergys aging management program; this report has been 10 marked and provided as Exhibit RIV000144, and reflects my analysis and opinions.
11 12 I relied on various documents in forming the opinions and conclusions in my report. Numerous 13 documents I have reviewed and relied upon in forming my opinions have been previously 14 submitted in this proceeding, and where discussed, are identified by their exhibit designations. I 15 have also relied on additional documents in forming my opinions; these documents have been 16 provided as Exhibits RIV000145 to RIV000160, or by New York State as NYS000490, 17 NYS000507, NYS000510, and NYS000511. To the best of my knowledge, these are all true and 18 accurate copies of each document that I used and/or relied upon in preparing this testimony.
19 20 Q. Please describe how your supplemental report and analysis (RIV000144) relate to 21 your initial testimonies on Contention NYS-38/RK-TC-5.
22 A. My initial testimonies on Contention NYS-38/RK-TC-5 related to Entergys failure to 23 demonstrate that metal fatigue of reactor components will be adequately managed during the 24 proposed periods of extended operation at the plant as required by 10 C.F.R. § 54.21(c). In 25 particular, my testimony criticized Entergys failure to expand the scope of its fatigue analysis, 26 and discussed Entergys then-vague and inadequate commitment (regulatory Commitment 43) to 27 determine the most limiting locations for Indian Point Unit 2 (IP2) and Indian Point Unit 3 (IP3) 28 and to conduct environmentally corrected fatigue analyses for any such locations. 7 My 29 testimony described what an analysis to determine the most limiting locations should entail, and 7

11 A. In my supporting report, RIV000144, I conducted an extensive assessment of Entergys 12 screening and refined fatigue evaluations. In brief summary, these analyses conducted on behalf 13 of Entergy for Indian Point were flawed in various respects. In particular, and as detailed in my 14 report, the screening and subsequent refined fatigue evaluations (1) failed to adequately consider 15 the impact of dissolved oxygen on fatigue life; 10 (2) failed to consider synergistic aging effects 16 of radiation, thermal embrittlement, and stress corrosion cracking on fatigue life; 11 and (3) 17 improperly relied on CUF values of record without adequately accounting for changes in 18 geometry, surface finish, heat transfer, strain rate, and radiation. 12 Based on such a flawed 19 analysis, Entergys efforts to expand the scope of its fatigue assessment was inadequate and 20 incomplete, and Entergy has continued to fail to conduct an appropriately expanded, bounding 21 analysis of the most limiting locations at Indian Point. 13 Various components that are subject to 22 and may succumb to metal fatigue during the proposed periods of extended operation for Indian 8

6 Q. What conclusions have you drawn related to Entergys additional fatigue 7 evaluations, with respect to Entergys Commitment 43 to determine the most limiting 8 locations and conduct refined analysis for any such locations?
9 A. As discussed in my report, based on my review of Entergys screening and refined 10 fatigue analyses, Entergy has failed to adequately determine the most limiting locations for 11 Indian Point and to conduct the necessary expanded fatigue analysis for the plants. 16 Also as I 12 discuss in my report, this failure represents a significant safety risk at Indian Point.17 It, thus, 13 remains my conclusion that Entergy has failed to demonstrate that metal fatigue will be 14 adequately managed at Indian Point during the proposed periods of extended operation. 18 15 16 Q. Have the opinions and conclusions you submitted in your earlier testimonies related 17 to Contention NYS-38/RK-TC-5 changed as a result of Entergys additional fatigue 18 evaluations?
19 A. No, they have not. The analysis, opinions, and conclusions I discussed in my earlier 20 written testimonies remain valid and applicable, as Entergy has continued to fail to conduct an 21 appropriate expanded fatigue analysis.

Docket Nos. 50-247-LR & 50-286-LR Pre-filed Supplemental Testimony of Dr. Joram Hopenfeld In support of NYS-38/RK-TC-5 1 Q. Please describe how your supplemental report and analysis (RIV000144) relate to 2 the additional bases of Contention NYS-38/RK-TC-5 that were admitted by the ASLB on 3 March 31, 2015. 19 4 A. The amended bases of Contention NYS-38/RK-TC-5 that were advanced by the ASLB, 5 and for which I submitted an expert declaration, relate to Entergys aging management plan for 6 RVI components. In particular, as memorialized in the SSER2, subsequent to the submission of 7 my earlier testimonies related to Contention NYS-38/RK-TC-5, Entergy expressed its intention 8 to rely on its Fatigue Monitoring Program (FMP) to manage the effects of fatigue on RVI 9 components at Indian Point during the periods of extended operation; in order to account for the 10 effects of the reactor coolant environment on the fatigue of RVI components as required under 11 the ASME Code Section III, Subsections NG-2160 and NG-3121, Entergy committed, in 12 regulatory Commitment 49, to recalculating CUF values for RVI components to include reactor 13 coolant environmental effects. 20 The supplemental bases of Contention NYS-38/RK-TC-5 that 14 were admitted into this proceeding contended, among other things, that Entergys commitment to 15 recalculate the CUF values of RVI components to include reactor coolant environment effects 16 involved a flawed methodology that failed to accurately and fully account for environmental 17 effects, and, thus, assure that fatigue of such components will be adequately managed during the 18 period of extended operation. 21 Entergy has conducted such fatigue evaluations for RVI 19 components, 22 and my report, Exhibit RIV000144, assesses the adequacy of those analyses.
20 21 Q. What are your opinions on Entergys fatigue evaluations for RVI components, with 22 respect to Entergys Commitment 49?
23 A. In my supporting report, Exhibit RIV000144, I conducted an extensive assessment of 24 Entergys fatigue evaluations related to RVI components. As discussed above, and detailed in 19 In the Matter of Entergy Nuclear Operations, Inc. (Indian Point Nuclear Generating Units 2 and 3), Docket Nos.

Docket Nos. 50-247-LR & 50-286-LR Pre-filed Supplemental Testimony of Dr. Joram Hopenfeld In support of NYS-38/RK-TC-5 1 my expert report, these analyses conducted on behalf of Entergy for Indian Point were flawed in 2 various respects since they (1) failed to adequately consider the impact of dissolved oxygen on 3 fatigue life; 23 (2) failed to consider the effects of radiation and stress corrosion; 24 and (3) 4 improperly relied on CUF values of record without adequately accounting for changes in 5 geometry, surface finish, heat transfer, strain rate, and radiation. 25 Based on such a flawed 6 analysis, Entergys evaluations related to RVI components are inaccurate and fail to demonstrate 7 that such components will not exhaust their fatigue lifeCUFen >1.0sometime during the 8 proposed extended periods of operation. 26 Importantly, as I discuss in my report, Entergys 9 flawed analysis represents a significant safety risk at Indian Point. 27 10 11 Q. What conclusions have you drawn related to Entergys fatigue evaluations for RVI 12 components?
13 A. As discussed in my report, based on my review of Entergys additional fatigue analyses 14 related to RVI components, it is my professional opinion that Entergy has failed to demonstrate 15 that the effects of metal fatigue on RVI components will be adequately managed at the Indian 16 Point facilities during the proposed period of extended operation. 28 17 18 Q. Do you have any additional comments on Entergys Commitment 49 for managing 19 the effects of fatigue on RVI components during the proposed periods of extended 20 operations?
21 A. Yes. As I discussed in my supporting declaration to Riverkeeper and New York States 22 amended contention, in Commitment 49 Entergy proposed (and NRC Staff agreed) that it need 23 not complete the calculation of CUFen values for IP3 RVI components until December 2015. 29 24 The schedule for Entergys resolution of this issue extends beyond the time frame for the 23 Supplemental Report of Dr. Joram Hopenfeld in Support of Contention NYS-26/RK-TC-1B and Amended Contention NYS-38/RK-TC-5 (June 9, 2015), at § 2 (Exhibit RIV000144).

Docket Nos. 50-247-LR & 50-286-LR Pre-filed Supplemental Testimony of Dr. Joram Hopenfeld In support of NYS-38/RK-TC-5 1 hearings in this ASLB proceeding and thus will not allow for a testing of the adequacy of the 2 proposed resolution of these issues in this proceeding. That timeline likely will prevent 3 Riverkeeper from playing any meaningful role in their development or resolution. Entergys 4 commitment to complete CUFen evaluations for RVI components in the future, without review 5 by the public, the ASLB, and/or NRC Staff, is unacceptable. By merely making a future 6 commitment, it is not possible to fully determine the adequacy of the calculated CUFen values 7 and Entergys AMP for RVI components. An adequate analysis must be performed before a 8 determination is made about license renewal. NRC Staffs acceptance of Entergys commitment 9 49 in the SSER2 to conduct environmentally corrected metal fatigue evaluations for RVI 10 components at some time in the future is not warranted or acceptable. By failing to undertake 11 and complete an adequate CUFen analysis now and not in the future, Entergy has failed to 12 demonstrate that metal fatigue of RVI components will be adequately managed during the PEO.
13 14 Furthermore, Entergy has not yet developed inspection acceptance criteria for baffle former bolts 15 in either IP2 or IP3. 30 Instead, it has agreed to develop a technical justification including 16 acceptance criteria for baffle former bolts sometime prior to the first round of anticipated 17 inspections, which might not occur until 2019 for IP2 and 2021 for IP3 and would be after an 18 evidentiary hearing in this proceeding. 31 The schedule for Entergys resolution of this issue 19 extends beyond the time frame for the hearings in this ASLB proceeding and thus will not allow 20 for a testing of the adequacy of the proposed resolution of this issue in this proceeding. That 21 timeline likely will prevent Riverkeeper from playing any meaningful role in their development 22 or resolution.
23 24 Q. Does this conclude your supplemental testimony regarding Contention NYS-38/RK-25 TC-5?
26 A. Yes.
