Harvesting of Aged Materials from Operating and Decommissioning Nuclear Power Plants M. Hiser3 , P. Purtscher3, P. Ramuhallib, A. B. Hull3 , R. Tregoning 3 , and C. E. Moyer3 au.s. Nuclear Regulatory Commission (NRC), Washington, D.C., USA bPacific Northwest National Laboratory (PNNL), Richland, WA, USA Recent developments in the nuclear industry include stronger interest in extended plant operation and plans to shut down a number of nuclear power plants (NPPs) In the U.S. , there is strong interest in extending NPP lifespans through subsequent license renewal (SLR) from 60 to 80 years.

Extended plant operation and SLR raise a number of technical issues that may require further research to understand aging mechanisms. U.S. utilities and the U.S . Nuclear Regulatory Commission (NRC) have focused on the aging of systems, structures, and components and in particular fou r key SLR issues: reactor pressure vessel (RPV) embrittlement, irradiation-assisted stress corrosion cracking ofreactor internals, concrete structures and containment degradation, and electrical cable qualification and cond ition assessment. Meanwhile, in recent years, a number of NPPs, both in the U.S. and internationally, have shut down or announced plans to shut down for various reasons, including economic, political, and technical challenges. Unlike in the past when there were very few plants shutting down, these new developments provide opportunities for harvesting components that were aged in representative Iight water reactor (LWR) environments.

In a third related development, economic challenges and limited budgets have restricted the resources available to support new research, including harvesting programs. Given this constrained budget environment, aligning interests and leveraging with other organizations is important to allow maximum benefit and value for future research programs.

NRC has recently undertaken an effort, with the assistance of Pacific Northwest National Lab (PNNL), to develop a strategic approach for harvesting aged materials from NPPs. Due to limited opportunities, past harvesting efforts have been reactive to individual plants shutting down and beginning decommissioning. Given the expected ava ilability of materials from numerous plants and anticipated research needs to better understand aging out to 80 years of operation, the NRC is pursuing a more proactive approach to prioritize the data needs best addressed by harvesting and identify the best sources of materials to address high-priority data needs for regulatory research.

The first step in this strategic approach is to prioritize data needs for harvesting. A data need describes a particular degradation scenario (combination of material and environment) and should be defined with as much detail as appropriate in terms of the material (alloy, compos ition, etc.)

and environment (temperature, fluence, chemistry, etc.).

A number of criteria may be considered when prioritizing the data needs for harvesting, including:

Applicability of harvested material for addressing critica l gaps o Harvesting for critical gaps prioritized over less essential technical gaps.

Ease of laboratory replication of the degradation scenario o For example, simultaneous the1mal and irradiation conditions are difficult to replicate or accelerated aging may not be feasible for a mechanism sensitive to dose rate.

Un ique field aspects of degradation o For example, unusual operating experie nce or legacy materials (fabrication methods, composition, etc.) no longer available.

Fleet-wide vs. plant-specific applicability of data o Greater value in addressing an issue applicable to a larger number of plants.

Harvesting cost and complexity o For example, harvesting unirradiated concrete or e lectrical cables less expensive and less complex than harvesting from the reactor internals or RPV.

Availability of reliable in-service inspection (ISi) techniques for the material / component o If mature inspection methods exist and are easy to apply to monitor degradation, harvesting may be less valuable.

Availability of materials for harvesting

Timeliness of the expected research results re lative to the objective.

The above potential criteria provide a systematic approach to prioritize data needs for harvesting.

Different organizations may weigh and consider each of these criteria differently based on their interests and perspectives, but each criteria is likely relevant to some degree for any organ ization.

NRC is interested in engaging with other o rganizations to prioritize data needs for harvesting and identify areas of common interest.

Another activity NRC is pursuing is the potential deve lopment of a database for sources of materials for harvesting, which could include both previously harvested materials and those available for future harvesting. This database would allow for aligning of high-priority data needs to the available sources of materials. As with the data needs effort, the level of detail for the sources of materials database should be appropriate for the factors influencing decision-making. NRC is interested in engaging with other organizations to develop a database for sources of materials for harvesting.

NRC 's experience is that harvesting can yield highly representative and valuable data on materials aging, but these efforts may be expensive and challenging. Having a clearly defined objective and early engagement with other stakeholders, including the NPP from which harvesting will take place, are key to success. As specific harvesting opportunities are identified through this strategic approach, the NRC welcomes opportunities for cooperation and leveraging resources with other interested research organizations.

Harvesting of Aged Materials from Operating and Decommissioning Nuclear Power Plants M. Hiser3 , P. Purtscher3, P. Ramuhallib, A. B. Hull3 , R. Tregoning 3 , and C. E. Moyer3 au.s. Nuclear Regulatory Commission (NRC), Washington, D.C., USA bPacific Northwest National Laboratory (PNNL), Richland, WA, USA Recent developments in the nuclear industry include stronger interest in extended plant operation and plans to shut down a number of nuclear power plants (NPPs) In the U.S. , there is strong interest in extending NPP lifespans through subsequent license renewal (SLR) from 60 to 80 years.

Extended plant operation and SLR raise a number of technical issues that may require further research to understand aging mechanisms. U.S. utilities and the U.S . Nuclear Regulatory Commission (NRC) have focused on the aging of systems, structures, and components and in particular fou r key SLR issues: reactor pressure vessel (RPV) embrittlement, irradiation-assisted stress corrosion cracking ofreactor internals, concrete structures and containment degradation, and electrical cable qualification and cond ition assessment. Meanwhile, in recent years, a number of NPPs, both in the U.S. and internationally, have shut down or announced plans to shut down for various reasons, including economic, political, and technical challenges. Unlike in the past when there were very few plants shutting down, these new developments provide opportunities for harvesting components that were aged in representative Iight water reactor (LWR) environments.

In a third related development, economic challenges and limited budgets have restricted the resources available to support new research, including harvesting programs. Given this constrained budget environment, aligning interests and leveraging with other organizations is important to allow maximum benefit and value for future research programs.

NRC has recently undertaken an effort, with the assistance of Pacific Northwest National Lab (PNNL), to develop a strategic approach for harvesting aged materials from NPPs. Due to limited opportunities, past harvesting efforts have been reactive to individual plants shutting down and beginning decommissioning. Given the expected ava ilability of materials from numerous plants and anticipated research needs to better understand aging out to 80 years of operation, the NRC is pursuing a more proactive approach to prioritize the data needs best addressed by harvesting and identify the best sources of materials to address high-priority data needs for regulatory research.

The first step in this strategic approach is to prioritize data needs for harvesting. A data need describes a particular degradation scenario (combination of material and environment) and should be defined with as much detail as appropriate in terms of the material (alloy, compos ition, etc.)

and environment (temperature, fluence, chemistry, etc.).

A number of criteria may be considered when prioritizing the data needs for harvesting, including:

Applicability of harvested material for addressing critica l gaps o Harvesting for critical gaps prioritized over less essential technical gaps.

Ease of laboratory replication of the degradation scenario o For example, simultaneous the1mal and irradiation conditions are difficult to replicate or accelerated aging may not be feasible for a mechanism sensitive to dose rate.

Un ique field aspects of degradation o For example, unusual operating experie nce or legacy materials (fabrication methods, composition, etc.) no longer available.

Fleet-wide vs. plant-specific applicability of data o Greater value in addressing an issue applicable to a larger number of plants.

Harvesting cost and complexity o For example, harvesting unirradiated concrete or e lectrical cables less expensive and less complex than harvesting from the reactor internals or RPV.

Availability of reliable in-service inspection (ISi) techniques for the material / component o If mature inspection methods exist and are easy to apply to monitor degradation, harvesting may be less valuable.

Availability of materials for harvesting

Timeliness of the expected research results re lative to the objective.

The above potential criteria provide a systematic approach to prioritize data needs for harvesting.

Different organizations may weigh and consider each of these criteria differently based on their interests and perspectives, but each criteria is likely relevant to some degree for any organ ization.

NRC is interested in engaging with other o rganizations to prioritize data needs for harvesting and identify areas of common interest.

Another activity NRC is pursuing is the potential deve lopment of a database for sources of materials for harvesting, which could include both previously harvested materials and those available for future harvesting. This database would allow for aligning of high-priority data needs to the available sources of materials. As with the data needs effort, the level of detail for the sources of materials database should be appropriate for the factors influencing decision-making. NRC is interested in engaging with other organizations to develop a database for sources of materials for harvesting.

NRC 's experience is that harvesting can yield highly representative and valuable data on materials aging, but these efforts may be expensive and challenging. Having a clearly defined objective and early engagement with other stakeholders, including the NPP from which harvesting will take place, are key to success. As specific harvesting opportunities are identified through this strategic approach, the NRC welcomes opportunities for cooperation and leveraging resources with other interested research organizations.

FW: RE: Draft slides Attachments: Ex-Plant Materials Harvesting Workshop.pptx, NRC Technical Data Needs for Harvesting.pptx Hi Pradeep, Thank you for sharing these slides. We've attached a PP that we are distributing to speakers and attendees describing the workshop overall as well as expectations for each session. We just developed this in the past few days, and are starting to distribute now. Please take a look for your awareness.

These slides are a good starting point, but are a little too broad for the sessions we're envisioning.

For the first presentation in session 2, focus on capturing Section 3.3 from the draft report you sent a couple days ago. So focus on the criteria for prioritizing harvesting data needs and the examplles that PNNL analyzed in the report: CASS, cables, DMWs, internals. We are planning a very short NRC slot in session 2 to cover more comprehensively NRC's data needs for harvesting; we want you t o cover the criteria and 4 examples and we'll lay out the whole range of high-priority data needs for metals, cables, and concrete. ITe current draft of our slides is attached for you awareness. Plus, we don't want to explicitly focus on SLR, but talk about long-term operation.

From the slides you have now for session 2, here are some suggestions:

I would delete slide 2 because it is high-level and should be captured in Session 1.

Keep slide 3 to capture briefly Ch. 2 ideas: why do harvesting, which leads to prioritization criteria

Add a slide to capture Section 3.1/3.2 on lit review/ basis for information

Add slide or two on criteria: why these criteria, how are they applied/used

Add several slides going through examples (maybe 1 slide/example) and how criteria led to an outcome o In other words, explain why we're interested in harvesting cables, CASS, and internals, but not DM welds so much

That's it!

For session 5 slides, put the focus on Section 4.2 from your report with references to 4.1 (harvesting experience) as needed to explain why we'd like various pieces of information for harvesting planning.

Suggestions on specific slides:

Delete slides 11/12 - don't need to cover info tool in this presentation

Maybe 1 or 2 background slides referring to harvesting experience (Ch. 4.1) in general

Focus several slides on Section 4.2 going in-depth on what information is needed for harvesting planning

o This presentation sets the stage in Session 5 for a discussion of harvesting plans from the various participants, so we want to thoroughly systematically lay out what information we think is helpful for informed decision-making Thanks!

[External_Sender) Harvesting Workshop Announcement

Dear Dr. Tregoning and Dr. Hiser,

Dr. Rosseel ofORNL kindly let me know that the USNRC is organizing a material harvesting workshop in March, and I am writing you to ask if there is any chance for us to participate and contribute, somehow, to the workshop.

We, CRTEPT, are working with Torn and Dr. Sokolov ofORNL on the characterization ofRPV materials from Zion Unit I under the US-Japan collaboration. We also have some discussions in Japan about materials harvesting from decomissioned Japanese LWRs because some of the Japanese utilities decided permanent shutdown of some of the old LWRs. So, materials harvesting is becoming a hot topic in Japan, and we are very much interested in participating in the workshop.

I would appreciate if our participation in the workshop is acceptable with the USN RC, and if so, please let me know your current idea about the scope o f the workshop so that we can discuss how we can contribute to the workshop.

I would like to send at least one researcher from CRIEPI, but some people from other organizations in Japan may also like to participate.

I look forward to hearing from you.

Best regards, Naoki Naoki Soneda, Dr.

[External_Sender) Re: Harvesting Workshop Announcement

Dear Rob,

Sorry for my late response. l talked to several stakeholders about our presentation at the workshop. At this point of time, it looks we should make a presentation in Session I on the motivation for harvesting.

CRJEPI has a lot of experiences on characterizing materials from nuclear reactors. We would like to talk about our motivation for harvesting in light of such experiences.

I learned that I need to stay within Japan during that week, and Dr.

Taku Arai and Dr. Sadao Higuchi will participate the workshop from CRTEPI. These two people are deeply involved in the discussions on future possible researches of decommissioned materials in Japan, even though such discussions arc still in a very early stage. So I think they can contribute to discussions in other sessions as well.

I would appreciate if you could provide me with any new information about the workshop so that my colleagues can start preparing for the workshop. You can find their e-mail addresses in the Cc: fields of this message.

[External_Scnder] Harvesting Workshop Announcement

Dear Dr. Tregoning and Dr. H iser,

>>> Dr.Rosseel of ORNL kindly let me know that the USNRC is organizing a material harvesting workshop in March, and I am writing you to ask if there is any chance for us to participate and contribute, somehow, to the workshop.

>>> We, CRlEPI, are working with Tom and Dr. Sokolov of ORNL on the characterization of RPY materials from Zion Unit I under the US-Japan collaboration. We also have some discussions in Japan about materials harvesting from decomissioned Japanese L WRs because some of the Japanese utilities decided permanent shutdown of some of the old LWRs. So, materials harvesting is becoming a hot topic in Japan, and we are very much interested in participating in the workshop.

>>> I would appreciate if our participation in the workshop is acceptable with the USNRC, and if so, please let me know your current idea about the scope of the workshop so that we can discuss how we can contribute to the workshop.

>>> I would like to send at least one researcher from CRIEPI, but some people from other organizations in .Japan may also like to participate.

>>> I look forward to hearing from you.

Ex-Plant Materials Harvesting Workshop March 7-8, 2017 USNRC HQ Rockville, MD, USA

Motivation

With plants shutting down both in the U.S. and internationally, there are increasing opportunities to harvest components from decommissioning plants

- Past harvesting efforts generally more reactive as opportunities arose, rather than proactively planned

Ex-plant materials may be valuable because they have been exposed to actual in-service plant operating conditions

- Can reduce the uncertainty associated with the applicability of the aging conditions

Insights from research on harvested materials can address technical data needs identified for extended plant operation

Lessons learned from past harvesting programs can help improve future harvesting efforts Challenges encountered in previous programs can be shared and mitigated or avoided in future programs

Approach

Domestic and international researchers, industry, regulators, and decommissioning companies' discuss benefits and challenges with ex-plant harvesting

- Encourage sharing of lessons learned as well as areas of common interest

Workshop consists of topical sessions with short presentations and significant time for open discussion

- Goal is to maximize engagement among meeting participants

Scope includes any materials aging issue that could benefit from harvesting, including metals, cables, and concrete

Expected Outcome

Participants become better informed and aware of the benefits and challenges associated with ex-plant harvesting

Discussions help identify areas of common interest for harvesting to address technical data needs

Presentations and discussions provide the starting point for a "database" of harvested materials and future harvesting opportunities

Contacts are made among research organizations to allow for further discussion of specific harvesting projects

Session Expectations

Session 1 Motivation for Harvesting Perspective from panel participants on their organizations' interest in and motivation for harvesting Brief (5-10 minute) presentation from each panel member followed by general discussion

Session 2 Technical Data Needs for Harvesting

- Presenters share high-priority data needs that may be best addressed by harvesting

Where does harvesting hold particular value compared to other sources of technical data 15-20 minute presentations followed by open discussion of technical data needs for harvesting

Session Expectations

Session 3 Sources of Materials Information on previously harvested materials and future harvesting opportunities

Materials located at research and vendor facilities

Decommissioning plants that may allow for future harvesting Short 5-10 minute presentations followed by open discussion Starting point for potential database of previously harvested materials and future harvesting opportunities

Session 4 Harvesting Experience: Lessons Learned and Practical Aspects Improving future efforts with lessons learned from past programs

Pitfalls to avoid and strategies to improve likelihood of success Practical perspective from non-researchers on how harvesting interfaces with the decommissioning process International decommissioning and harvesting experience 20-30 minute presentations followed by open discussion

Session Expectations

Session 5 Future Harvesting Program Planning

- Technical and logistical information needed when planning a specific harvesting program Perspective from panel participants on the workshop Next steps and actions from workshop Potential areas of common interest for future harvesting programs Brief (5-10 minute) presentation from each panel member followed by general discussion

Ex-Plant Materials Harvesting Workshop Location: NRC Headquarters in Rockville, MD, USA Dates: March 7-8, 2017 Motivation:

There are increasing opportunities to harvest the safety-critical components from decommissioning plants, both domestic and international.

The harvested materials are valuable because they have been exposed to actual in-service plant operating conditions (temperature, irradiation ,

coolant, etc.), unlike virgin materials tested under simulated conditions in the lab.

Data from ex-plant materials should help address technical gaps identified for extended operation of nuclear power plants due to highly relevant aging conditions.

Purpose and Objective:

For NRC staff and interested stakeholders to have greater awareness and knowledge of the benefits and challenges associated with ex-plant harvesting.

Facilitate contacts and communication to enable Q O O O O 0 specific cooperative ex-plant harvesting programs to be initiated.

Workshop Topics: .. , . 'i.. "

Harvesting decision-making and prioritization o Technical data needs best addressed by harvesting o Technical information needed in advance of harvesting

Sources of materials:

o Decommissioning reactors o Operating reactors - replaced components o Previous harvesting programs - "boneyards" o Tracking availlable materials

Harvesting process o Lessons learned from harvesting experience o Perspective of utility-owner and decommissioning contractor on harvesting o Communication and coordination between decommissioning and researchers

International collaborative programs on specific components at specific plants Workshop will consist of solicited presentations followed by discussion periods. If interested in attending or learning more about the workshop, please reach out to the contacts below.

Harvesting Workshop Attachments: Harvesting Workshop Announcement.docx, Condensed Workshop Agenda 12-12-16.docx T.G.:

I hope that this email finds you well and that you and your family are now settled inl(b)(S) I 1*m writing for a favor from you. In early March, we're hosting a materials harvesting workshop. I've attached the workshop announcement and the condensed agenda.

You can see that we are planning five unique sessions as part of the workshop. Each session has a specific theme, or objective, as outlined below (andl in the attached agenda).

1. Session 1 will consist of short presentations and a panel discussion on the motivation for harvesting.

2. Session 2 will discuss data needs best met through harvesting.

3. Session 3 will discuss sources of materials for harvesting programs

4. Session 4 will discuss lessons-learned from past harvesting programs and practical aspects associated with harvesting.

5. Session 5 will attempt to summarize the workshop and planning a harvesting program, as well as discuss actions and next steps Robin Dyle and Sherry Bernhoft are participating from EPRI and will provide that perspective.

However, we are also looking for some targeted international participation. We were therefore thinking that someone from MAI might be good to participate in Session 2 (or possibly another session).

What are your thoughts on this idea and, if you think MAI may be able to contribute to the workshop, do you have a POC that you can provide me so that I can see if they're interested?

I hope you and your family have a Happy Holidays and a prosperous New Year.

Dear Bob,

dear Matt As you probably know, SCK* CEN is willing to attend the harvesting workshop USN RC is preparing and that would take place in the US in March 2017. If the workshop can be scheduled week 13 (27 to 31 March), that would be great because Eric and myself will be in the US. If case another date is selected, I will be able to attend but not Eric (other commitments). We are preparing a presentation that overviews what was already done worldwide in the field of post-mortem tests on decommissioned vessel materials. Please let us know as soon as possible the final planning that we can start with the necessary arrangements.

Looking forward to see you and discuss future actions for a fruitful international collaboration.

E. Moyer, M. Sircar, J. Philip, J. E. Pires, D. D. Murdock, T. Koshy, A. B. Hull U.S. Nuclear Regulatory Commission (NRC}, Washington , D.C., USA The U.S. Nuclear Regulatory Commission (NRC) issues licenses for commercial power reactors to operate for up to 40 years. These licenses may be renewed for multiple 20-year increments.

Now that 4 7 of the 99 operating commercial reactors in the U.S. have entered their first period of extended operation (PEO) to operate for up to 60 years, several licensees have indicated intention to apply within the next few years for subsequent license renewal (SLR} for an additional 20-year period. The NRC has revised its key guidance documents to be ready for the review of SLR applications and to communicate expectations for the aging management of passive, long-lived plant systems, structures, and components (SSCs). Regulatory research on the aging management of SSCs is being conducted now and will continue beyond the receipt of the initial SLR applications to confirm the adequacy of these guidance documents through the SLR period. Should regulatory research identify concerns related to aging management, regulatory guidance may be revised to reflect the new results. Regulatory research is ongoing in the following four areas: reactor pressure vessel neutron embrittlement, irradiation assisted stress corrosion cracking of reactor vessel internals, concrete and containment degradation, and electrical cable qualification and condition assessment. This paper will focus on regulatory research related to concrete degradation , including alkali-silica reaction and irradiation damage to concrete, and condition assessment of electrical cables.

Harvesting of Aged Materials from Operating and Decommissioning Nuclear Power Plants M. Hiser3 , P. Purtscher3, P. Ramuhallib, A. B. Hull3 , R. Tregoning 3 , and C. E. Moyer3 au.s. Nuclear Regulatory Commission (NRC), Washington, D.C., USA bPacific Northwest National Laboratory (PNNL), Richland, WA, USA Recent developments in the nuclear industry include stronger interest in extended plant operation and plans to shut down a number of nuclear power plants (NPPs) In the U.S. , there is strong interest in extending NPP lifespans through subsequent license renewal (SLR) from 60 to 80 years.

Extended plant operation and SLR raise a number of technical issues that may require further research to understand aging mechanisms. U.S. utilities and the U.S . Nuclear Regulatory Commission (NRC) have focused on the aging of systems, structures, and components and in particular fou r key SLR issues: reactor pressure vessel (RPV) embrittlement, irradiation-assisted stress corrosion cracking ofreactor internals, concrete structures and containment degradation, and electrical cable qualification and cond ition assessment. Meanwhile, in recent years, a number of NPPs, both in the U.S. and internationally, have shut down or announced plans to shut down for various reasons, including economic, political, and technical challenges. Unlike in the past when there were very few plants shutting down, these new developments provide opportunities for harvesting components that were aged in representative Iight water reactor (LWR) environments.

In a third related development, economic challenges and limited budgets have restricted the resources available to support new research, including harvesting programs. Given this constrained budget environment, aligning interests and leveraging with other organizations is important to allow maximum benefit and value for future research programs.

NRC has recently undertaken an effort, with the assistance of Pacific Northwest National Lab (PNNL), to develop a strategic approach for harvesting aged materials from NPPs. Due to limited opportunities, past harvesting efforts have been reactive to individual plants shutting down and beginning decommissioning. Given the expected ava ilability of materials from numerous plants and anticipated research needs to better understand aging out to 80 years of operation, the NRC is pursuing a more proactive approach to prioritize the data needs best addressed by harvesting and identify the best sources of materials to address high-priority data needs for regulatory research.

The first step in this strategic approach is to prioritize data needs for harvesting. A data need describes a particular degradation scenario (combination of material and environment) and should be defined with as much detail as appropriate in terms of the material (alloy, compos ition, etc.)

and environment (temperature, fluence, chemistry, etc.).

A number of criteria may be considered when prioritizing the data needs for harvesting, including:

Applicability of harvested material for addressing critica l gaps o Harvesting for critical gaps prioritized over less essential technical gaps.

Ease of laboratory replication of the degradation scenario o For example, simultaneous the1mal and irradiation conditions are difficult to replicate or accelerated aging may not be feasible for a mechanism sensitive to dose rate.

Un ique field aspects of degradation o For example, unusual operating experie nce or legacy materials (fabrication methods, composition, etc.) no longer available.

Fleet-wide vs. plant-specific applicability of data o Greater value in addressing an issue applicable to a larger number of plants.

Harvesting cost and complexity o For example, harvesting unirradiated concrete or e lectrical cables less expensive and less complex than harvesting from the reactor internals or RPV.

Availability of reliable in-service inspection (ISi) techniques for the material / component o If mature inspection methods exist and are easy to apply to monitor degradation, harvesting may be less valuable.

Availability of materials for harvesting

Timeliness of the expected research results re lative to the objective.

The above potential criteria provide a systematic approach to prioritize data needs for harvesting.

Different organizations may weigh and consider each of these criteria differently based on their interests and perspectives, but each criteria is likely relevant to some degree for any organ ization.

NRC is interested in engaging with other o rganizations to prioritize data needs for harvesting and identify areas of common interest.

Another activity NRC is pursuing is the potential deve lopment of a database for sources of materials for harvesting, which could include both previously harvested materials and those available for future harvesting. This database would allow for aligning of high-priority data needs to the available sources of materials. As with the data needs effort, the level of detail for the sources of materials database should be appropriate for the factors influencing decision-making. NRC is interested in engaging with other organizations to develop a database for sources of materials for harvesting.

NRC 's experience is that harvesting can yield highly representative and valuable data on materials aging, but these efforts may be expensive and challenging. Having a clearly defined objective and early engagement with other stakeholders, including the NPP from which harvesting will take place, are key to success. As specific harvesting opportunities are identified through this strategic approach, the NRC welcomes opportunities for cooperation and leveraging resources with other interested research organizations.

Given the challenges we have had with getting UN Rs through management review and concurrence, less UNRs may be better. If necessary, the title can be changed to reflect broader scope. By the way, the UNRs we expect to receive from NRO and NMSS will also be "umbrella" type UNRs.

This really does not fit the objective of developing a general database for ex-plant materials (metals, concrete and cables).

Further, these points were niot vetted with DLR during our staff and management briefings on t his UNR. I would prefer not to surprise them by inserting things like this, w hich are not directly addressing the objective.

If you still insist, I will add t hese to t he final version.

Raj ifhe EMDA ranking of each aging-related degradation phenomena incorporates multiple factors t hat may not be adequately resolved by additional coupon testing of ex-plant materials.

issues that the industry has not yet developed a generic technical basis to support its resolution, the NRC will request applicants to address the technical issues with plant-specific programs in their SLR applications. The staff will review these plant-specific programs that address the SLR technical issues, but anticipates a longer application review process in these cases.

The requested research described below would provide information to support the staff in effectively evaluating aging management practices and developing staff positions to augment staff's preparedness for the evaluation of the feasibility of future applications for an SLR period.

These requested products should build upon analysis methods, tools, and expertise developed as part of ongoing research activities and new research activities focused specifically on aging effects during an SLR period of extended operation (i.e., 60 to 80 years).

Hold NRC/industry workshop( s) o n status of domestic and international research activities and operating experience to address and evaluate the status of materials degradation issues, identified in the EMDA reports, for a subsequent license renewal Commented [HAS): I think this should not be the first.

These meetings have been helpful in faci litating technical discussions, disseminating knowledge and information, and enabling the understanding of technical challenges, and paving the path-forward for resolution of the challenges and issues related to materials degradation during the SLR period of operations. As the NRC staff prepare for the review of the future SLR submittals, there is a need for continued engagement with domestic nuclear industry and other industries, DOE and other federal organizations, academia, international partners, and interested public stakeholders, through workshops targeted toward the status and resolutions of major technical issues outlined in the SRM and identified in IEMD~.

operations. RES staff should proviide an annual technical letter report summarizing the understanding gained through the workshops/meetings. The summary should include the status of domestic and international research activities in addressing materials degradation issues and aging management practices for an SLR period of operations.

The report should also discuss (1) areas of progress and issues resolution, (2) areas of insufficient progress that may warrant additional NRC interactions, and (3) any newly identified technical issues that should be considered for an SLR period of operations.

Schedule: The effort should last no more than 36 months from the period of inception of this user need request.

B. Provide RES staff assessments of the current knowledge and disposition of materials degradation issues identified in the EMDA documents Technical Need: As mentioned earlier, the EMDA volumes identified significant technical issues for nuclear power reactor operations beyond 60 years related to materials degradation. The major materials degradation issues fall under the following four topical areas, as outlined in SRM on SECY 14-0016:

Reactor pressure vessel neutron embrittlement at high fluence; Irradiation assisted stress corrosion cracking of reactor internals and primary system components;

Concrete and containment degradation; and Electrical cable qualification and condition assessment.

The NRC, DOE, and industry a re addressing the key technical issues related to materials degradation at NPPs, in order to gain better understanding of the materials aging and degradation mechanisms and their implications of structural and component integrity. DOE/LWRS and the industry have initiated numerous research activities on the four major technical areas. The NRC staff conducts confirmatory research, through several user need requests on specific technical issues, to independently verify licensee data, determine safety margins, and explore uncertainties. Results from NRC's research will be used, in part, to confirm the adequacy of industry's technical basis for SLR and the associated AMPs. The AMPs are cornerstones for managing materials degradation in SSCs during SLR. In addition, the NRC research will support and increase the efficiency of staff review of SLR applications. To fully support the staff review of the SLR applications, RES should develop staff assessments of the current knowledge and disposition of materials degradation issues related to the four major technical areas. The assessments should also include recommendations on the need for:

any interim staff guidance (ISG) to address aging management issues, and

new regulatory guidance and/or revision of existing ones to address uncertainties in knowledge and/or potential non-conservativisms..

Deliverable: Deliver a technical letter report that summaries the state-of-knowledge and current knowledge and disposition of materials degradation issues identified in EMDA. The report should also include recommendations on the need for any new or revised guidance to address component integrity of aging structures.

Schedule: The effort should last no more than 36 months from the period of inception of this user need request. The initial draft report should be completed by the end of FY 2018.

license renewal. Historically, this research has included laboratory testing on fresh materials under simulated aging conditions as well as testing and characterization of ex-plant materials harvested from nuclear power plants. Ex-plant materials a re extremely valuable because they have been exposed to actual in-service plant operating conditions (temperature, irradiation, coolant, etc.), unlike fresh materials tested under simulated conditions in the lab. Ex-plant materials reduce the uncertainty associated with the applicability of the aging conditions compared to fresh materials aged under simulated conditions. Therefore, this research is expected to provide fundamental insights on reactor materials degradation and information addressing potential technical issues or identified gaps to support anticipated future NRC needs. It will also further inform the value of existing databases based on simulated aging conditions by assessing their applicability to in-service conditions.

Based on the recent experience of recovering materials from decommissioned plants, such as Zion, Crystal River and Zorita (Spain), the efforts of planning, coordination and eventual harvesting of these materials is resource-intensive and time-challenging. Future efforts to retrieve materials from decommissioned plants should be focused on the highest value SSCs by proactively developing a strategic database for obtaining unique and significant materials aging degradation information from ex-plant components. Such a database will enable the NRC to focus its harvesting efforts and expeditiously obtain materials and components from plants to be decommissioned in the near future and develop information and knowledge to access the efficacy of the AMPs.

Deliverable: RES should develop a database for strategic harvesting containing information on:

research gaps for SLR that may be best addressed by harvesting due to challenges in simulating actual service conditions, and

materials that can be harvested from to-be-decommissioned NPPs and ex-plant components from operating plants to better inform the NRC's AMPs and aging-related regulatory oversight and to better plan research activities.

RES should deliver periodic reports assessing the effectiveness of such programs and recommending any improvements for a subsequent license renewal period.

Commented [HAS]: May need more time, we need to discuss further.

G. Provide technical assistance, as needed, for preparation of review of SLR applications.

Technical Need: As the NRR staff prepares for the anticipated SLR application in FY18, technical assistance from RES staff on emergent issues may be needed. Such issues may include, but not restricted to, ~echnical support for aging management program audits, public meetin~s related to communication efforts, and confirmatory reviews of licensee submittals.

Amy, Thank you very much for your insightful comments. I will address your comments and send a revised one. We had promised DLR to provide this early May. I had been pressed with other issues.

We did have a brief with both DLR staff and management on the four items. Certainly, you can talk with Bennett.

I think the AMP effectiveness audits and any plant-specific AMP can be captured in the last technical assistance task, as more specifics emerge as time goes on .

I agree with you on combining Task A and C. The Task Con Domestic and international collaboration was added as a separate item because Allen requested that.

This UNR was initially specific to getting a closure on EMDA issues and disposition (Task A-C).

I would prefer restricting this UNR to 2-3 years. We could move the strategic harvesting to a different UNR if that would require more time.

access to industry and international operating experience databases which deal with failures of SSCs experienced during plant operation. Because the first plants have just recently entered the initial renewed license operating period, there is limited operating experience information specifically re lated to aging management issues. To address this gap, research activities are in place to obtain materials degradation data through laboratory tests. However, obtaining data from materials harvested from decommissioned plants and ex-plant components will be crucial bridging the gap between data obtained from simulated experiments in laboratory and service-life components. This research is expected to provide fundamental insights on reactor materials degradation and information addressing potential technical issues or identified gaps to support anticipated future NRC needs. Thus, the NRC needs to keep abreast of opportunities to recover materials from plants that are being decommissioned or from ex-plant components.

Based on the recent experience of recovering materials from the decommissioned plants, such as Zion and Crystal River, the efforts of planning, coordination and eventual collection of these materials could be resource-intensive and time-challenging. Future efforts to retrieve materials from decommissioned plants could be accelerated by pro-actively developing a strategic database for obtaining unique and significant materials aging degradation information from diverse sources.

Steve, I have attached a revised version of the enclosure that includes some of Pat's comments. The assessment of appropriate t esting is referenced in Task E.

On the "gap" of small-scale vs. large scale t est ing is not new. There has been ample work. But, for components experiencing IAD, there may not be a full understanding.

I do not think there was a public comment on this for GALL-SLR. But, I could be wrong.

As you had suggested, we can an internal alignment on Pat's idea and pursue it with NRR.

There are at least cou ple of options - Task E (emergent need) from this UNR or IAD U NR.

Perhaps, there are more options.

For now, I have added a phrase (highlighted) in the deliverable of Task E.

"Such issues may include, but not restricted to, providing an assessment of effect of specimen size on the prediction of component performance, technica l support for aging management program audits, publ ic meetings related to communication efforts, and confirmatory reviews of licensee submittals."

Raj, Was this issue raised during the public comment period of the GALL-SLR or SRP-SLR?

If the identification of a gap in EMDA is new, it needs to be communicated to RES/DE management before we send specifics on it in a draft document to DLR. The EMDA is a RES deliverable, so obviously, RES/DE management should be briefed on it before we notify our counterparts in NRR. Perhaps, you or Pat could add wording to the draft that will allow us to be more specific in our response.

Any thoughts?

This really does not fit the objective of developing a general database for ex-plant materials (metals, concrete and cables).

2016-NRR-UNR-Draft-May 2016 abh rev.docx Raj , my two cents worth.

User Need Evaluate the Aging Management of Systems, Structures, and Components for Subsequent License Renewal

Background:

Although the NRC staff can accept subsequent license renewal (SLR) applications now, the review would be based on guidance provided in NUREG-1800, Revision 2, "Standard Review Plan for Review of License Renewal Applications for Nuclear Power Plants" and NUREG-1801 ,

Revision 2, "Generic Aging Lessons Learned (GALL) Report - Final Report." Because this guidance applies to plants operating from 40-60 years, additional review would be needed to ensure that the applicant addressed issues anticipated during 60-80 years of plant operation for SLR. Such reviews would be longer and more resource-intensive. To improve the efficiency of SLR application reviews, the NRC staff has undertaken several activities to revise the guidance documents. These activities include reviews of aging management practices, plant audits, technical information exchanges with industry and Department of Energy (DOE), and confirmatory research .

In cooperation with the DOE Light Water Reactor Sustainability (LWRS) Program, the NRC completed NUREG/CR-7153, "Expanded Materials Degradation Assessment (EMDA), Vol. 1-5" (ADAMS Accession Nos. ML14279A321 , ML14279A331, ML14279A349, ML14279A430, ML14279A461) to identify the most significant technical issues for nuclear power reactor operation beyond 60 years. The EMDA ranked the significance, current knowledge, and uncertainty associated with aging-related degradation phenomena that could affect systems, structures, and components (SSCs) over 80 years of operation. As outlined in the staff requirements memorandum (SRM) on SECY 14-0016, the major technical issue areas are:

Reactor pressure vessel neutron embrittlement at high fluence;

Irradiation-assisted stress corrosion cracking of reactor internals and primary system components;

Concrete and containment degradation; and

Electrical cable qualification and condition assessment.

The NRC staff conducted several audits to investigate the effectiveness of aging management programs (AMPs). The findings are documented in the report titled , "Summary of Aging Management Program Effectiveness Audits to Inform Subsequent License Renewal: R.E. Ginna Nuclear Power Plant and Nine Mile Point Nuclear Station, Unit 1" (ML13122A007). The development of SLR guidance was based on NUREG-1800 and NUREG-1801, the understanding gained from the audits, NUREG/CR-7153 {EMDA), an evaluation of domestic and international operating experience of nuclear plants, lessons learned from staff review of previous license renewal applications, and assessment of recent research findings. Draft SLR guidance documents were issued in December 2015, as draft "Generic Aging Lessons Learned for Subsequent License Renewal (GALL-SLR) Report," (NUREG-2191, Volumes 1 and 2) and draft "Standard Review Plan for Review of Subsequent License Renewal Applications for Nuclear Power Plants" (SRP-SLR) (NUREG-2192).

Since the draft guidance documents were issued, the staff has held several public meetings with stakeholders and the public to discuss the proposed revisions and bases for the revisions. The most recent meetings were held on January 21 and February 19, 2016. Going forward, the NRC staff will continue to lead outreach activities to stakeholders and the public in order to

provide information on the proposed changes to the guidance documents, solicit feedback on the documents, and revise the documents, as appropriate, to reflect stakeholder and public feedback. The final guidance documents are expected to be issued in mid-2017.

To support the review of an SLR application, an applicant will need to demonstrate how the effects of aging will be managed, including those associated with the technical issues listed above. Although the industry is conducting research to address these major technical issues for SLR, not all the research will be completed before the first application is submitted. For those issues that the industry has not yet developed a generic technical basis to support its resolution ,

the NRC will request applicants to address the technical issues with plant-specific programs in their SLR applications. The staff will review these plant-specific programs that address the SLR technical issues, but anticipates a longer application review process in these cases .

The requested research described below would provide information to support the staff in effectively evaluating AMPs and developing staff positions on the technical issues identified in EMDA reports. This effort will also augment the staff's preparedness for the evaluation of the feasibility of future applications for an SLR period. These requested products should build upon analysis methods, tools, and expertise developed as part of ongoing research activities and new research activities focused specifically on aging effects during an SLR period.

Description of Scope and Tasks A. Hold NRC/industry workshop(s) on status of domestic and international research activities and operating experience to address and evaluate the status of materials degradation issues identified in the EMDA reports for SLR.

Technical Need: In February 2008, the NRC and DOE first co-sponsored a "Workshop on U.S. Nuclear Power Plant Life Extension Research and Development" (ADAMS Accession Number ML080570419), which requested stakeholder input into aging management research areas for "Life Beyond 60." Since then, there have been multiple workshops/meetings on the research activities and operating experience that may impact aging management of SSCs for an SLR period. These meetings have been helpful in facilitating technical discussions, disseminating knowledge and information, enabling the understanding of technical challenges, and paving the path forward for resolution of the challenges and issues related to materials degradation during the SLR period. As the NRC staff prepares for the review of SLR applications, there is a need for continued engagement with domestic industry, DOE and other federal organizations, academia, international partners, and interested public stakeholders through workshops focused on the status and resolution of major technical issues outlined in the SRM and identified in EMDA.

Deliverable: RES staff should facilitate several workshops/meetings on operating experience from the initial license renewal period , research results on materials degradation issues, and aging management of SSCs during the SLR period.

These meetings should be specifically targeted toward the resolution of technical issues for effective aging management of SSCs during the SLR period. RES staff should provide an annual technical letter report summarizing the understanding gained through the workshops/meetings. The summary should include the status of domestic and international research activities in addressing materials degradation issues and aging management practices during the SLR period. The report should also discuss (1) areas of progress and issues resolution, (2) areas of insufficient progress that may warrant additional NRC-driven

interactions, and (3) any newly identified technical issues that should be considered .

Schedule: The effort should last no more than 36 months from the period of inception of this user need request.

B. Provide RES staff assessments of the current knowledge and disposition of materials degradation issues identified in the EMDA reports Technical Need: As mentioned earlier, the EMDA reports identified significant technical issues for nuclear power reactor operations beyond 60 years related to materials degradation. These issues fall under the following four topical areas, as outlined in SRM on SECY 14-0016:

Reactor pressure vessel neutron embrittlement at high fluence;

Irradiation-assisted stress corrosion cr.acking of reactor internals and primary system components;

Concrete and containment degradation; and

Electrical cable qualification and condition assessment.

The NRC, DOE, and industry are addressing the key technical issues related to materials degradation at NPPs. In order to gain better understanding of the materials aging and degradation mechanisms and their implications of structural and compo nent integrity, DOE and the industry have initiated numerous research activities on the four major technical areas. The NRC staff conducts confirmatory research, through several user need requests on specific technical issues, to independently verify licensee data, determine safety margins, and explore uncertainties. In addition, the NRC research will support and increase the efficiency of staff review of SLR applications. To fully support the staff review of the SLR applications, RES should develop staff assessments of the current knowledge and disposition of materials degradation issues related to the four major technical areas. The assessments should also include recommendations on the need for:

any interim staff guidance (ISG) to address aging management issues, and

new regulatory guidance and/or revision of existing regulatory guides (RGs) to address uncertainties in knowledge and/or potential non-conservativism.

Deliverable: Deliver a technical letter report that summarizes the current knowledge and disposition of materials degradation issues identified in EMDA. T he report should also include recommendations on the need for any new or revised guidance to address component integrity of aging structures.

Schedule: The effort should last no more than 36 months from the period of inception of this user need request. The initial draft report should be completed by the end of FY 2018.

C. Develop and implement a long-term strategy for obtaining information on materials degradation from decommissioned NPPs, as well as from ex-plant components from operating plants.

Technical Need: The NRC performs confirmatory research to inform and develop the technical basis for regulatory decisions related to aging management programs for

SLR. Historically, this research has included testing small-scale specimens or coupons on virgin materials under simulated aging conditions, as well as testing and characterization of ex-plant materials harvested from nuclear power plants. Ex-plant materials are valuable because they have been exposed to actual in-service plant operating conditions (temperature, irradiation, coolant, etc.), unlike virgin materials tested under simulated conditions in the lab. Testing ex-plant materials also reduces the uncertainty associated with the applicability of the aging conditions. Therefore, this effort is expected to provide fundamental insights on reactor materials degradation and information addressing potential technical issues or identified gaps to support anticipated future NRC needs. It will also inform the value of existing databases based on simulated aging conditions by assessing their applicability to in-service conditions.

Based on the recent experience of recovering materials from decommissioned plants, such as Zion, Crystal River and Zorita (Spain), the efforts of planning, coordination and eventual harvesting of these materials could be resource-intensive and time-challenging. Future efforts to retrieve materials from decommissioned plants should be focused on the highest value SSCs by proactively developing a strategic database for obtaining unique and significant materials aging degradation information from ex-plant components. Such a database will enable the NRC to focus its harvesting efforts and expeditiously obtain materials and components from plants to be decommissioned in the near future and develop information and knowledge to assess the efficacy of the AMPs.

Deliverable: RES should develop a database covering the four topical areas outlined in SRM on SECY 14-0016 and containing information on:

research gaps for SLR that may be best addressed by harvesting due to challenges in simulating actual service conditions, and

materials that can be harvested from to-be-decommissioned NPPs and ex-plant components from operating plants to better inform the NRC's AMPs and aging-related regulatory oversight and to better plan research activities.

RES should deliver periodic reports assessing the effectiveness of such programs and recommending any improvements for the SLR period.

Schedule: The effort should last no more than 36 months from the period of inception of this user need request.

D. Continue to Develop Domestic and International Partnerships to Share Expertise, Capabilities and Resources Related to Aging Management Research for Long-Term Operations (LTO)

Technical Need: Various domestic and foreign research organizations, government agencies, utilities and research organizations are presently engaged in aging management research, the results of which may be of value to the NRC regarding plant operations during the SLR period. Additionally, the Electric Power Research Institute (EPRI) is engaged with various international resea rch organizations to develop data on aging mechanisms/effects. As such, it benefits the NRC to be engaged in domestic and international research partnerships in order to evaluate all available operating experience and relevant research , leverage resources and minimize unnecessary

duplication of efforts. It would be advantageous to the NRC to develop partnerships with these entities such that the various research programs could be better coordinated and focused on high-priority needs.

Deliverable: Continue to develop agreements with domestic and international partners to collaborate on aging management research that results in information to help inform agency decisions regarding SLR and long-term operations. Integrate as appropriate the results of these collaborative research and information exchanges from international partnerships into Tasks A and B. Provide an annual summary of international collaborative research results and status of interactions (e.g ., references to meeting minutes, presentations, technical reports, etc.), highlighting international activities and results that may affect SLR.

Schedule: The effort should continue until the closure of this user need request.

E. Provide technical assistance, as needed, for preparation of review of SLR applications.

Technical Need: As the NRR staff prepares for the anticipated SLR application in FY18, technical assistance from RES staff on emergent issues may be needed. Such issues may include, but not restricted to, providing an assessment of effect of specimen size on the prediction of component performance, technical support for aging management program audits, public meetings related to communication efforts, and confirmatory reviews of licensee submittals.

Schedule: This effort, as needed, should continue until the closure of this user need request.

Is that OK with systems, structures, and components (SSCs) f o r ~ a Subsequent License you? (Bennett and I worked together to write the last Renewal (SLR) PeJckxl UNR) Also feedback is needed now from people such as John Burke who has been really closely involved with SLR work. Can I also talk to John?

Background:

Certainly, you can talk to Bennett and John or others.

Alth ough the NRC staff can accept subsequent license renewal applications now, the review We have had several meetings with DLR staff and would be based on guidance provided in' NUREGs-1800 and -18011. Because the guidance in management on the five tasks describe here. Allen these NU RE Gs is based on plant operation from 40-60 years, additional review would be wanted Task C to be separate from A. Also, we will not needed to ensure that the applicant addressed issues unique to 60-80 years of plant operation close the old UNR (2010-006) at this point. I believe for subsequent license renewal.
