!Note to requester: Attachment is immediately following.

Thanks for your input - I think it reads better and more clearly. I cleaned up the formatting and references per PLiM guidelines.

I agree with your suggestion to refocus the one criteria from available inspection methods to confidence in AMP. However, given that we already have slides and a poster with the old language, I didn't change the title of that particular criteria in the paper, but I will take tlnat into account in developing these criteria for us to discuss in a couple weeks.

If anyone else could provide input by noon today, then I will share with Steve this afternoon to hopefully smooth the path to approval by Monday from division management.

Thanks!

HARVESTING OF AGED MATERIALS FROM OPERA TING AND DECOMMISSIONING UCLEAR POWER PLANTS M. Hiser, P. Purtscher, A. B. Hull, R. Tregoning U. S. Nuclear Regulatory Commission, Office of Nuclear Regulatory Research Washington, DC Email: matthew.hiser@nrc.gov P. Ramuhalli Pacific Northwest National Laboratory Richland, WA, USA Abstract Recent developments, including strong interest in extended plant operation and plans to shut down a number of nuclear power plants (NPPs), provide opportunities for harvesting components that were aged in representative light water reactor (L WR) environments. Technical issues associated with extended plant operation, such as reactor pressure vessel (RPV) embrilllement, irradiation-assisted degradation of reactor internals and primary components, concrete structures and containment degradation, and electrical cable aging, may be used to focus harvesting efforts on high-priority issues.

Harvesting can provide highly representative aged materials for research and may be the only practical source of representative aged materials in some cases. Harvesting can be expensive and time-consuming, which makes it essential to focus on those technical needs with the highest importance and cooperate with multiple organizations whenever possible to optimally leverage resources. NRC is interested in engaging with other organizations to prioritize data needs for harvesting, identify areas of common interest, and develop a database for sources of materials for harvesting.

I. BACKGROUND 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 [ I]. Further research may be required to understand age-related degradation throughout the SLR period to help ensure that aging management programs are adequate.

U.S. utilities and the U.S. Nuclear Regulatory Commission (NRC) are focused on the aging of systems, structures, and components in four key technical areas: reactor pressure vessel (RPV) embrinlement, irradiation-assisted degradation of reactor internals and primary components, concrete structures and contaimnent degradation, and electrical cable aging [2]. In recent years, a number ofNPPs, 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 decommissioning plants, these plant shutdowns provide opportunities for harvesting components that were aged in representative I ight water reactor (L WR) environments. Additionally, harvesting programs can be costly and complex. Given these constraints, aligning interests and leveraging with other organizations is important to allow maximum benefit and value for future research programs.

2. NRC EXPERIENCE WITH HARVESTING NRC has significant experience with harvesting plant components and performing research on harvested materials to address technical issues. This experience includes a range of components from plants in various stages of operation both in the U.S. and internationally. Some of the harvesting projects that the NRC has participated in have studied the following materials or components:

RPV materials from the decommissioned Gundrernmingen plant to study fluence rate effects on RPY embrittlement [3],

Cast austenitic stainless steel (CASS) materials from the decommissioned Shippingport reactor. to study CASS thermal embrittlement [4],

RPV materials from the unfinished or never-operated Shoreham and Midland plants to improve understanding of flaw distributions for RPV embrittlement concerns [5-6],

RPV head control rod drive mechanism penetrations from the operating North Anna and Davis-Besse plants to study primary water stress corrosion cracking (PWSCC) of nickel alloys and the effectiveness ofnon-destructive evaluation (NDE) methods (8-12],

Reactor coolant system (RCS) piping nozzle weld materials from the operating V.C. Summer plant to study PWSCC of nickel alloys [I 1-12],

Reactor internals materials from the decommissioned Jose Cabrera (known as Zorita) plant to study high-fluence irradiation effects on stainless steel alloys [ 13],

Aluminum-based neutron-absorbing materials from the decommissioned Zion plant to study degradation in the spent fuel pool environment [ 14 ],

Electrical cables from the decommissioned Zion and Crystal River plants to investigate cable degradation [15],

Electrical bus ducts from the decommissioned Zion plant to study high-energy arc faults in electrical enclosures [ 16].

As illustrated by these programs, NRC's experience is that harvest.ing has contributed significantly to improved understanding of important technical issues for nuclear safety. For RPV materials, harvesting has increased knowledge of embrittlement mechanisms and the underlying flaw distributions in the RPV to allow reduction in unnecessary conservatism. For nickel alloys, harvesting has improved understanding of PWSCC and the development of acceptable inspection intervals, while also increasing confidence in the ability of NOE methods to detect and characterize flaws. Finally, recent work on electrical enclosures has helped to identify a potential new safety issue associated with high-energy arc faults in electrical components containing aluminum

[ 16].

3. NRC PERSPECTIVE AND LESSONS LEARNED FROM HARVESTING ACTIVITIES From NRC's perspective, a principal role of harvesting is to confitm other research results from simulated aging conditions. In many situations, accelerated aging through higher nux test reactor irradiations or elevated temperatures can be used to generate significant data to understand aging effects in a more cost-effective manner.

Limited harvesting efforts of materials from highly representative se1vicc environments can help confirm the adequacy of the knowledge gained from accelerated aging studies, and thus increase the confidence in the broader knowledge base.

However, in certain situations, harvesting may be the only practical source of representative aged materials.

For example, achieving high tluence levels with representative irradiation conditions through accelerated aging can be very challenging. Additionally, it is essential to gain as much information as possible regarding the materials and environment (temperature, tluence, irradiation conditions, chemistry, humidity, etc.) in advance before committing to a specific harvesting project so that the implications of the results from evaluating the materials can be properly understood.

Pragmatically, harvesting can be expens ive, complex, and time-consuming; therefore, focusing on technical needs of high importance will help ensure good value. Likewise, leveraging and cooperation among multiple organizations helps to mitigate cost challenges. It is also quite challenging to transport irradiated materials, particularly internationally, so minimizing or avoiding transportation of such materials is highly recommended.

4. NRC ACTIVITIES ON HARVESTfNG NRC is potentially interested in harvesting materials to assess age-related degradation in the four technical areas identified previously: reactor pressure vessel (RPV) embrittlement, irradiation-assisted degradation of reactor internals and primary components, concrete structures and containment degradation, and electrical cable aging [2]. The focus is to understand the impact of extended plant operation on material behavior, including the effects of higher tluences and longer exposures to aging conditions.

NRC has recently undertaken an effort, with the assistance of Pacific Northwest National Laboratory (PNNL), to develop a strategic approach for harvesting aged materials from NPPs. Past harvesting activities have been narrowly focused on the relatively few opportunities to get materials from decommissioning plants. Given the expected availability of materials from numerous plants and identified research needs to better understand aging out to 80 years of operation, the NRC is developing 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.

5. PRIORITIZATION OF DATA NEEDS BEST ADDRESSED BY HARVESTING The first step in this strategic approach is to prioritize data needs for harvesting. A data need describes a particular degradation scenario (i.e., combination of material and environment) and should be defined with as much detail as appropriate in terms of the material (e.g., alloy, composition) and environment (e.g., temperature, fluence, chemistry).

A number of criteria are being considered for prioritizing the harvesting data needs, including:

Applicability of harvested material for addressing critical gaps Harvesting to address critical gaps should be prioritized over less essential technical gaps Ease of laboratory replication of the degradation scenario Degradation mechanisms that are harder to replicate under simulated aging conditions are of higher priority for harvesting. For example, simultaneous thermal and irradiation conditions are difficult to replicate outside of the plant environment. Alternatively, accelerated aging may not be feasible for a mechanism sensitive to dose rate. These two degradation mechanisms may be best evaluated using harvested materials.

Unique field aspects of degradation For example, legacy materials (e.g., fabrication methods, composition) that arc no longer available, but may play an important role in a potential degradation mechanism, would have a higher priority than harvesting materials that can be obtained from other sources.

Fleet-wide vs. plant-specific applicability of data There is greater value in developing knowledge to address an issue that may be applicable to a larger number of plants compared to one that may only affect a relatively small number of plants.

Harvesting cost and complexity Activities witJ1 higher costs and complexity are less attractive than similar activities with lower costs and that are simpler to execute.. For example, harvesting unirradiated concrete or electrical cables is less expensive and less complex than harvesting from the reactor internals or RPV.

Availability of reliable inspection methods for the degradation scenario If mature inspection methods exist and arc easy to apply to monitor degradation, harvesting may be less valuable. lf inspection methods do not exist, harvesting may be essential to ensure confidence in the assessment of age-related degradation in that particular component.

Timeliness of the expected research results The ability of a potential harvesting program to provide timely results to support either a technical or regulatory need is important. Having high confidence that results will be timely increases the priority.

Availability of materials for harvesting The availability of materials to harvest for a particular data need is clearly essential and increases the priority.

The above potential criteria provide a systematic approach for prioritizing harvesting data needs. Different organizations may uniquely weigh these criteria differently, but the criteria are intended to be comprehensive.

NRC is interested in engaging with other organizations to further refine these criteria, use them to prioritize data needs for harvesting, and ultimately identify areas of common interest that may provide optimal harvesting opportunities.

6. DATABASE OF SOURCES OF MATERIALS FOR HARVESTING The NRC is also developing a database that identities sources of materials for harvesting. This database will include both previously harvested materials and those which may be available for future harvesting. This database will be used to align the high-priority harvesting needs to the available materials. As with the harvesting prioritization 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 that identities sources of materials for harvesting.

7. CONCLUSIONS NRC's experience is that harvesting can yield highly representative and valuable knowledge about materials aging. However, these efforts may be expensive and challenging. Having a clearly defined objective and early engagement with other stakeholders, including the decommissioning plant where harvesting will take place, are necessary to ensure project success. As specific harvesting opportunities are identified through this strategic approach, the NRC will develop strategies for pursuing these opportunities. The NRC also welcomes collaboration from other interested research organizations both in developing the proactive harvesting strategy and in pursuing harvesting opportunities of mutual interest.

Meg, Matthew, Patrick:

Many thanks for your help with this. The presentation looks good and it will be useful for having a targeted discussion on the topic and hopefully we will see some interest from them in this area. I made a few simple formatting changes to a few slides so they all have similar fonts (see attached).

Could you also provide me a reference for the PNNL report (i.e., title and report number)? I'd specifically like to let them know about this report and let them know that we are planning to have it completed sometime in the fall. I'm going to add this as a bullet to one slide.

Matt:

Can I get you to add another slide which summarizes, at a high level the harvesting workshop and then has a reference to the workshop summary report? Basically just a reminder of dates, attendance, agenda/discussion topics, and then the reference to the report. Since Kazu attended the meeting I don't think there are any issues with giving them the summary. Do you agree?

Motivation

~

U.S.NRC United States Nuclear Regulatory Commission Protecting Peopl.e and the Environment

• US utilities are interested in extending operating lifespans from to 60-80 years:

• Key technical areas for aging management:

• RPV embrittlement, irradiation-assisted degradation of internals, concrete structures and containment, electrical cables

• Many plant shutdowns worldwide provide opportunities to harvest components during decommissioning

• Harvesting can provide valuable information on aging mechanisms to increase confidence in aging management

• Limited budgets make cooperation for new research, including harvesting, essential:

• Important to align interested parties

• Leverage resources for maximum benefit

NRC Harvesting Experience

~

U.S.NRC United States Nuclear Regulatory Commission Protecting Peopl.e and the Environment

• NRC has participated in several programs:

• RPV, CRDM penetrations, RCS piping, RPV internals, neutron absorbers, and cables

• Materials harvested from unfmished, operating and decommissioning plants

• US and international programs

• NRC experience is there is significant value in using harvested components to confirm data from other research programs

Hi Carol, Hiser, Matthew Fri, 1 Jun 2018 19:14:50 +0000 Moyer, Carol Purtscher, Patrick;Audrain, Margaret;Tregoning, Robert RE: L TMD (SLR) Research Update Nothing really major. Here's the latest ongoing:

We met with the electrical and concrete folks a couple weeks ago to share what we've been doing in the metals area to prioritize technical needs for harvesting and ask them to do something similar.

Pat is trying to finish up the PNNL report (address NRR's comments) in near future.

We're nearly finished with getting information on previously harvested materials at national labs, etc. Just today we got input from Battelle in Columbus, OH, which has a number of pipes (both large and small) that were harvested and used in earlier research. The last big one will be Meg visiting PNNL late this month or next month (can't remember).

RE: LTMD (SLR) Research Update

Matt, Thanks very much for this recap. It is helpful for my near-term needs.

The main thing about which I was unsure was which tests, if any, were being done in-pile at Halden, and therefore would be the most impacted and most difficult to replicate elsewhere.

Irradiations would be delayed, if moved, but could be accomplished at other facilities. Based on your email's attachments, we were planning to use the Halden in-pile CGR capabilities for welds, and in-pile creep/SR for baffle bolts. But it is only the welds that are high-priority work, and the in-pile feature is not critical to this work.

Does that sound right? Please correct me if I have mis-characterized the situation.

RE: LTMD (SLR) Research Update Hi Carol, We have provided the attached documents to Brian and Chris (and others higher up) regarding our mitigation plan for a Halden shutdown. This has been a fast-moving activity over the past 3 weeks since we received word that Halden would likely decommission.

Essentially the most important IAD activity impacted by Halden is the further irradiation of stainless steels welds for IASCC CGR and FT (the first bullet in your list of IAD work). We will plan to work with EPRI to determine an alternate facility to perform this work, which we both consider high priority. Our rough estimate is a 2-4 year delay and >$1M cost increase to perform this work elsewhere.

For the 3 dpa CASS work, my understanding is those materials were irradiated at Halden, but are now at ANL, so there is no further dependency on Halden (is that right Sri?).

The other update on IAD related to void swelling is that the baffle bolts from Indian Point and Ginna that are now at Westinghouse will be in the DOE library likely within the next two months. We've received some temperature and fluence information on those bolts that seems to indicate they might be interesting to look at for void swelling. We also may be interested to look at them for baffle bolt degradation research as well (pending alignment within RES and NRR).

Let me know if you have any questions or need more info. I'll be stopping work around 3:15 today.

While I'll be in external training next week, I'll be checking email at least once a day.

Thanks!

LTMD (SLR) Research Update Hello, Sri and Matt, I will be briefing Brian next week on the status of Long-Term Materials Degradation research (that is, research related to subsequent license renewal), which includes IAD. Brian Harris had asked for some input and updates last month, but he was told that nothing really had changed in the IAD portion of the program.

Now that the Halden shut-down is all but certain, our near-and medium-term plans for irradiated materials testing will have to be adjusted. I must ask you both to take another look at my summary document (attached), and also the slide set that Steve Frankl used for the EPRI materials meeting last week (attached). I have inserted notes about expected programmatic risk due to the evolving Halden situation. But if you can give me more specific guidance on how our plans will change - do less, do the same work but with some delays, do something different,

? - I would very much appreciate it.

I am in the office today, so you can call me if you would like to discuss this. Thanks in advance!

Dogan, Once Jose and I complete our input, 1 will send it to you for review.

Matt requested to get it by 9/ 14.

Thanks, Mita

FW: Materials Harvesting Hi Kenn and Mita, I just wanted to follow up from this meeting/email back in May on harvesting priorities. I have attached a template of the prioritization of harvesting needs in the metals area. Can you follow that template to provide input for the electrical and concrete technical areas?

Please let me (or Meg or Pat on cc) know if you have any questions.

Thanks!

Motivation

~

U.S.NRC United States Nuclear Regulatory Commission Protecting Peopl.e and the Environment

• Interest in extending lifespan to 60-80 years

• Need to understand aging mechanisms

• Key areas: RPV embrittlement, IASCC of internals, concrete structures and containment degradation and electrical cables

• Announced plant shut downs worldwide -

opportunities to harvest in situ components

• Limited budgets have restricted new research, including harvesting

• Important to align interested parties

• Leverage resources for maximum benefit J

NRC Harvesting Experience

~

U.S.NRC United States Nuclear Regulatory Commission Protecting Peopl.e and the Environment

• NRC has participated in several programs:

• RPV, CRDM penetrations, RCS piping, RPV internals, neutron absorbers, and cables

• Materials harvested from unfinished, operating and decommissioning plants

• US and international programs

• Determined significant value in using harvesting components to confirm data from other research programs

Lessons Learned

~

U.S.NRC United States Nuclear Regulatory Commission Protecting Peopl.e and the Environment

• Technical

• Provides highly representative ages materials for research

• Important to gain as much information as possible before committing to specific harvesting project

• Logistical

• Expensive and time-consuming effort

• Leveraging resources helps mitigate cost challenges

• Transportation of irradiated materials is cumbersome and time-consuming

Current Work

~

U.S.NRC United States Nuclear Regulatory Commission Protecting Peopl.e and the Environment

• Develop strategic approach to materials harvesting

• Past efforts have been reactive to individual plants shutting down

• Prioritize data needs best addressed by harvesting, considering:

• Applicability of harvested material for addressing gaps Importance of harvested materials over laboratory aging

• Fleet-wide vs plant-specific applicability of data

• Regulatory considerations

• Harvesting cost/complexity

• Database for Sources of Materials Compilation of available materials at US national labs Eventually include materials previously harvested and available for future harvesting

• NRC is interested in engaging with other organizations in developing the database

Conclusion

~

U.S.NRC United States Nuclear Regulatory Commission Protecting Peopl.e and the Environment

• Harvesting can yield highly representative and valuable data on materials aging

• A focused approach to choosing harvested materials is necessary to get best outcomes

• NRC is working on a Sources of Materials Database and a Data Needs Prioritization scheme

• NRC welcomes opportunities for cooperation and leveraging with other interested research organizations

Discussion

~

U.S.NRC United States Nuclear Regulatory Commission Protecting Peopl.e and the Environment

• What (if any) activities are currently being undertaken in Japan for materials harvesting?

• Does Japan have an interest in harvesting? If so, what areas are considered most important?

• Would there be interest in leveraging resources if a harvesting project was identified?

Purpose

~

U.S.NRC United States Nuclear Regulatory Commission Protecting Peopl.e and the Environment

• Create a framework for a strategic approach to harvesting ex-plant materials to support regulatory needs associated with subsequent license renewal (SLR)

Ex-plant materials offer unique environmental exposure that cannot be entirely replicated by laboratory testing with fresh materials

• Align high priority data needs identified in SLR activities with harvesting opportunities from decommissioning plants

=

Background===

~

U.S.NRC United States Nuclear Regulatory Commission Protecting Peopl.e and the Environment

• To date, harvesting opportunities have been limited due to few decommissioning plants Zion in U.S., Zorita in Spain

• However, several U.S. plants have already shut down or are planning to do so in the near future Kewaunee, San Onofre, Crystal River, Vermont Yankee, Oyster Creek, Fort Calhoun, Clinton, Quad Cities, Diablo Canyon

• This provides a unique opportunity to plan harvesting to address the highest priority technical and regulatory is

Harvesting Experience

~

U.S.NRC United States Nuclear Regulatory Commission Protecting Peopl.e and the Environment

• Past harvesting efforts have generally involved reactive decision-making Limited opportunities to acquire ex-plant materials Limited strategic planning for harvesting

• Harvesting projects with NRC involvement:

Reactors internal materials from Zorita Concrete from Zorita Neutron absorber material from Zion Cables from Zion and Crystal River

Approach: Assessment of Technical Issues and Available Materials for Harvesting

~

U.S.NRC United States Nuclear Regulatory Commission Protecting Peopl.e and the Environment

• Utilize various sources of technical information with respect to anticipated degradation in NPPs out to 80 years of operation NRC, DOE, EPRI, IAEA

• Identify high-priority data needs that could be addressed through harvesting ex-plant materials Focus on identifying characteristics of important systems, structures, and components (SSCs) for harvesting

• Gather information on ex-plant material expected to be available based on identified needs May be from both operating and decommissioning_r=Pflll...-

Implementation

~

U.S.NRC United States Nuclear Regulatory Commission Protecting Peopl.e and the Environment

• What might the output of this activity look like?

For example, the review may show there is value in acquiring CASS material around 15% delta ferrite with various dose ranges

• Once that need is identified, this activity would identify what SSCs might be the best candidates for harvesting For example, perhaps lower support columns would be identified as the ideal SSC to address the CASS data need

• As decommissioning plants announce their plans, there is a clear list of SSCs and their characteristics (metallurgy, temperature, fluence, etc.) that would be desired t address the data need

Motivation

~

U.S.NRC United States Nuclear Regulatory Commission Protecting Peopl.e and the Environment

• US utilities are interested in extending operating lifespans from to 60-80 years:

• Key technical areas for aging management:

• RPV embrittlement, irradiation-assisted degradation of internals, concrete structures and containment, electrical cables

• Many plant shutdowns worldwide provide opportunities to harvest components during decommissioning

• Harvesting can provide valuable information on aging mechanisms to increase confidence in aging management

• Limited budgets make cooperation for new research, including harvesting, essential:

• Important to align interested parties

• Leverage resources for maximum benefit

NRC Harvesting Experience

~

U.S.NRC United States Nuclear Regulatory Commission Protecting Peopl.e and the Environment

• NRC has participated in several programs:

• RPV, CRDM penetrations, RCS piping, RPV internals, neutron absorbers, and cables

• Materials harvested from unfmished, operating and decommissioning plants

• US and international programs

• NRC experience is there is significant value in using harvested components to confirm data from other research programs

Lessons Learned

~

U.S.NRC United States Nuclear Regulatory Commission Protecting Peopl.e and the Environment

• Technical

• Provides highly representative aged materials for research

• Important to gain as much information as possible before committing to specific harvesting project

• Logistical

• Expensive and time-consuming effort

• Leveraging resources helps mitigate cost challenges

• Transportation of irradiated materials is cumbersome and time-consuming

Current Work

~

U.S.NRC United States Nuclear Regulatory Commission Protecting Peopl.e and the Environment

• Develop strategic approach to materials harvesting

• Past efforts have been reactive to individual plants shutting down

• Prioritize data needs best addressed by harvesting, considering:

• Applicability of harvested material for addressing gaps

• Importance of harvested materials over laboratory aging

• Fleet-wide vs plant-specific applicability of data

• Regulatory considerations

• Harvesting cost/complexity

• Database for Sources of Materials

• Compilation of previously harvested materials available at US national labs as well as those available for future harvesting

• NRC is interested in engaging with other organization

This is the only RES paper for PLiM. Once you have the paper and slides, l would expect that only a brief meeting will be necessary on this to make sure that we are in alignment on key messages and we can answer any questions that you have. The other thing that we'd like you at PLiM is represent us at a side-bar meeting on !FRAM. We will therefore need to get you up-to-speed on the efforts of IF RAM, the pl ayers at the side bar, and the objectives that we are trying to accomplish during that meeting. This effort may require more time to get you up to speed. I estimate that we will need between I - 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> to cover both topics, depending on the questions that you have and the level of discussion depth.

Your schedule is challenging. Can you identify a few windows between now and I 0/12 when we can meet to discuss both PLiM and the IFRAM side-bar meeting?

We are in the ' home stretch' for completing the work, and it should be ready, in draft, within the next week. Once we get all the material, we can consider what aspects of it you can deliver based on the agenda and how the research sessions align or not align with your sessions.

PLiM Conference Eric, George, Allen, After further discussion of this matter with Mike Weber, RES has decided to not participate in the PLiM Conference this year. Notwithstanding that George has been invited as Keynote speaker, and the RES travel was previously (initially) approved, Mike has expressed concerns that we are even planning on sending additional staff to the conference given all our higher priority program activities. He also thinks, and I agree, that we address research to support SLR through a number of-different venues in our interactions with the international community. Our plans were well intended, however, given our priorities coupled with our drive to be more efficient and effective in the conduct of research we will not participate in this year's PLiM Conference.

Please stop all activities to prepare for the research part of the conference. Thanks to all the staff who provided your support in preparation for RES to be presented in the conference.

MDLR comments on PNLL's Guidelines for Harvesting Materials for SLR Pat Following your request, I asked eight of our technical review staff to review and provide comments on PNNL's technical letter report on harvesting materials. Attached are general comments on the report and specific comments that I have compiled in red line/strikeout version of the report itself. Some of the comments are repetitious of comments made by other reviews. I have tried to group similar comments together.

When you have had a chance to review them, please see me if you have any questions.

I will try to answer your questions or get you to the right reviewer.

In spite of the rather negative comments on this report, we continue to believe that the Materials Harvesting Project will be in valuable in the future as the NRC deals with aging plants and needs an organized approach for selecting materials for harvesting withe the increased availability of sources.

Background and Motivation

• Recent trends in global nuclear industry:

Interest in extending nuclear power plant (NPP) lifespans Numerous NPPs, both in U.S. and internationally, have announced plans to or already have shut down

• Limited budgets have restricted the resources available to support new research, including harvesting programs Aligning interests and leveraging with other organizations is important to maximize value 3

~

U.S.NRC Unimi Sta[t.J S11dC'ar R.t-gula,ory Commission Prot<<:ting Pnlpk and tlw £nuiro111M11-t

NRC Harvesting Experience

• N RC has participated in numerous harvesting programs over the years:

RPV, CROM penetrations, RCS piping, RPV internals, neutron absorbers, and cables From unfinished, operating,and decommissioning plants in U.S. and internationally

• Significant value in using harvested components to confirm data from other research programs 4

~

U.S.NRC Unimi Sta[t.J S11dC'ar R.t-gula,ory Commission Prot<<:ting Pnlpk and tlw £nuiro111M11-t

Technical Lessons Learned

• Harvesting can provide highly representative aged materials for research May be only practical source of representative aged materials May be able to use limited harvested materials to validate larger accelerated aging data set

• Important to gain as much information as possible in advance before committing to specific harvesting project 5

~

U.S.NRC Unimi Sta[t.J S11dC'ar R.t-gula,ory Commission Prot<<:ting Pnlpk and tlw £nuiro111M11-t

Logistical Lessons Learned

• Harvesting is an expensive, time-consuming effort

• Leveraging resources with other research organizations helps mitigate cost challenges

• Transporting irradiated materials, particularly internationally, is cumbersome and time-consuming 6

U.S.NRC Unimi Sta[t.J S11dC'ar R.t-gula,ory Commission Prot<<:ting Pnlpk and tlw £nuiro111M11-t

Recent N RC Activities

• Strategic approach to materials harvesting Due to limited opportunities, past harvesting efforts have generally been reactive to individual plants shutting down

• Prioritize the data needs best addressed by harvesting

• Workshop held in March 2017 at NRC HQ to discuss all aspects of harvesting with other interested stakeholders 7

~

U.S.NRC Unimi Sta[t.J S11dC'ar R.t-gula,ory Commission Prot<<:ting Pnlpk and tlw £nuiro111M11-t

Potential Criteria for Harvesting Prioritization

• Applicability of harvested material for addressing critical gaps

• Ease of laboratory replication of the degradation scenario

• Unique field aspects of degradation

• Fleet-wide vs. plant-specific applicability of data 8

~

U.S.NRC Unimi Sta[t.J S11dC'ar R.t-gula,ory Commission Prot<<:ting Pnlpk and tlw £nuiro111M11-t

Potential Criteria for Harvesting Prioritization

• Harvesting cost and complexity

• Availability of reliable in-service inspection (ISi) techniques for the material/ component

• Availability of materials for harvesting

• Timeliness of the expected research results relative to the objective 9

~

U.S.NRC Unimi Sta[t.J S11dC'ar R.t-gula,ory Commission Prot<<:ting Pnlpk and tlw £nuiro111M11-t

Database for Sources of Materials

• NRC is pursuing the development of a database for sources of materials for harvesting

• Allow for aligning of high-priority data needs to the available sources of materials

• N RC is interested in engaging with other organizations in developing the database 10 Example of reactor internals harvesting plan

~

U.S.NRC Unimi Sta[t.J S11dC'ar R.t-gula,ory Commission Prot<<:ting Pnlpk and tlw £nuiro111M11-t

Conclusion and Path Forward

• Harvesting can yield highly representative and valuable data on materials aging

• Data Needs Prioritization and Sources of Materials Database

• As specific harvesting opportunities are identified, NRC welcomes opportunities for cooperation and leveraging with other interested research organizations 11

RE: NRAJ Bilateral Meeting Presentation on Harvesting Matt:

Just got a chance to look at this. Given that you've only got 1/2 hour, your 8 slides are probably the max. I would take more than 10 minutes to provide an overview of the activity. If you need to save time, slides 5 and 7 could be eliminated. You could provide them in the slide package but just gloss right over them in the presentation.

Obviously, Japan has a large number of plants that are shut-down. It's still not clear which of these plants will restart. Therefore, there may be a lot of harvesting opportunities there.

The main purpose of this discussion is to see if NRAJ has any activities (or planned activities) to identify harvesting opportunities. If so, it would be good to understand there approach. It would also be good to see if they know which plants are most likely to not restart.

With this in mind it would be good to have a slide or two with a list of questions or discussion topics on this issue to discuss with the Japanese. While we only have 1/2 hour, we may be flexible to extend the meeting if we need more discussion time on any topic.

Does this make sense?

Purpose

~

U.S.NRC United States Nuclear Regulatory Commission Protecting Peopl.e and the Environment

• Create a framework for a strategic approach to harvesting ex-plant materials to support regulatory needs associated with subsequent license renewal (SLR)

Ex-plant materials offer unique environmental exposure that cannot be entirely replicated by laboratory testing with fresh materials

• Align high priority data needs identified in SLR activities with harvesting opportunities from decommissioning plants

=

Background===

~

U.S.NRC United States Nuclear Regulatory Commission Protecting Peopl.e and the Environment

• To date, harvesting opportunities have been limited due to few decommissioning plants Zion in U.S., Zorita in Spain

• However, several U.S. plants have already shut down or are planning to do so in the near future Kewaunee, San Onofre, Crystal River, Vermont Yankee, Oyster Creek, Fort Calhoun, Clinton, Quad Cities, Diablo Canyon

• This provides a unique opportunity to plan harvesting to address the highest priority technical and regulatory is

Harvesting Experience

~

U.S.NRC United States Nuclear Regulatory Commission Protecting Peopl.e and the Environment

• Past harvesting efforts have generally involved reactive decision-making Limited opportunities to acquire ex-plant materials Limited strategic planning for harvesting

• Harvesting projects with NRC involvement:

Approach: Assessment of Technical Issues and Available Materials for Harvesting

~

U.S.NRC United States Nuclear Regulatory Commission Protecting Peopl.e and the Environment

• Utilize various sources of technical information with respect to anticipated degradation in NPPs out to 80 years of operation NRC, DOE, EPRI, IAEA

• Identify high-priority data needs that could be addressed through harvesting ex-plant materials Focus on identifying characteristics of important systems, structures, and components (SSCs) for harvesting

• Gather information on ex-plant material expected to be available based on identified needs May be from both operating and decommissioning_r=Pflll...-

Implementation

~

U.S.NRC United States Nuclear Regulatory Commission Protecting Peopl.e and the Environment

• What might the output of this activity look like?

For example, the review may show there is value in acquiring CASS material around 15% delta ferrite with various dose ranges

(<0.08 dpa, 1-3 dpa, and >5 dpa)

• Once that need is identified, this activity would identify what SSCs might be the best candidates for harvesting For example, perhaps lower support columns would be identified as the ideal SSC to address the CASS data need

• As decommissioning plants announce their plans, there is a clear list of SSCs and their characteristics (metallurgy, temperature, fluence, etc.) that would be desired t address the data need

Current N RC Activities

~

U.S.NRC United States Nuclear Regulatory Commission Protecting Peopl.e and the Environment

• NRC is working with Pacific Northwest National Lab (PNNL) to identify technical issues that may be best addressed by ex-plant harvesting Focused on unique value of harvesting to understand material properties in difficult to replicate environments

• NRC also seeking interest from other stakeholders to better understand availability of materials for harvesting Considering a public workshop in fall 2016 Stakeholders include EPRI, DOE, U.S. industry, international partners

Discussion Topics

~

U.S.NRC United States Nuclear Regulatory Commission Protecting Peopl.e and the Environment

• Japanese approach to ex-plant material harvesting

• Information on available harvesting opportunities from Japanese reactors Is it known which plants will not restart?

• Opportunities for coordination/ cooperation on ex-plant harvesting

RE: NRAJ Bilateral Meeting Presentation on Harvesting Matt:

Just got a chance to look at this. Given that you've only got 1/2 hour, your 8 slides are probably the max. I would take more than 10 minutes to provide an overview of the activity. If you need to save time, slides 5 and 7 could be eliminated. You could provide them in the slide package but just gloss right over them in the presentation.

Obviously, Japan has a large number of plants that are shut-down. It's still not clear which of these plants will restart. Therefore, there may be a lot of harvesting opportunities there.

The main purpose of this discussion is to see if NRAJ has any activities (or planned activities) to identify harvesting opportunities. If so, it would be good to understand there approach. It would also be good to see if they know which plants are most likely to not restart.

With this in mind it would be good to have a slide or two with a list of questions or discussion topics on this issue to discuss with the Japanese. While we only have 1/2 hour, we may be flexible to extend the meeting if we need more discussion time on any topic.

Does this make sense?

NRC/EPRI Management Meeting Brian/Chris:

I had a discussion yesterday during the NRC/lndustry material information meeting with Anne Demma of EPRI who was asking about the meeting next week and if we had any topics of interest for discussion. She wants to brief Kurt Edsinger in advance of the meeting. I told her that I would get back to her (today if possible). Last week we agreed that we would like to discuss 4 topics in the "opportunities to collaborate" related to materials in the DE portion of the meeting.

1.IAD

2. Harvesting 3.AM 4.xFEM I think we were also planning to have some discussion with EPRI on ANLWR materials collaboration under the DSA ANLWR topic. Do you want me to send Anne the brief bullets and the "asks" that we put together for you last week on each CMB topic? She can then pass them along to Kurt to ensure that we're in alignment prior to the meeting. I have the information that

we put together on IAD, harvesting, and AM. I can coordinate with Raj to make sure that I have the information for AM and ANLWR in advance of sending the email to Anne.

Just let me know how you would like me to proceed.

RE: NRC Form 1102, RIC PROPOSED DIGITAL PRESENTATION SUBMISSION FORM Good evening, Ms. Moyer.

Well, that was a pretty clean job. My edits are mostly minimal.

Find attached the files for your project, NRC Form 1102, RIC PROPOSED DIGIT AL PRESENTATION SUBMISSION FORM.

Since the text in the form does not permit tracking changes, I edited your text in a Word file. You'll see three Word files attached here: a _clean file, a _clean with comments file, and a _compare file.

Please use the _clean file going forward. The _clean_with_comments file includes additional comments you should review before you move forward. The _compare file includes all tracked changes and comments for your inspection.

If the text in the _clean Word file is satisfactory, and if you have modifed the document as needed with regards to the comments in the _clean with comments file, then just copy and paste the title and text from the Word file into your form and you're set to go.

Please consider this email as QTE concurrence with your project. Please let us know if you have any questions or concerns.

NRC/JNRA meeting during week of 9/17 Importance: High Meg/MatVPat:

Chris Regan and I are traveling to Japan in mid-September to meet with JNRA as part of our biannual materials research exchange. One of the agenda topics is material harvesting. In

preparation for the meeting, I am hoping that you can provide me with slides that summarize the state of our research activities and near-term plans. I'm hoping that much, if not all of this information will come from recycled talks and not require much additional burden on your end.

I'd also like you to consider the following questions related to RPV integrity:

1. What information would you like to get from JNRA?

2. What actions (e.g., future information, commitments, data sharing) would you like to see arise from this meeting?

You could include your questions for 1 and 2 as part of your presentation or you could simply send them to me in advance of the meeting.

I'm requesting that you provide me with this information by COB on 9/7. This will give me a week before the trip to make sure that we're aligned on the topic. I think it would be good if one of you coordinates all the input and I'm recommending Meg (since I'm going to hit Matt up on IAD) ©, but please just let me know you guys decide as lead for this request.

Thanks so much for your help on this. Please let me know if you have further questions as well.

I have only a few comments (attached). I think the key messages are on point. My only real quibble is stylistic. The slides are basically a ton of words. It would be nice to have some representative graphics or illustrations of some of the points just to break up the words.

However, I know it can take time to develop/find good representative graphics and given our limited window, I don't know if you want to tackle this or not. At a minimum, I recommend eliminating many of the sub-bullets and sub-sub-bullets from the slides themselves and moving them to the talking points. This will help Allen out as well.

Ill NRC Harvesting Experience

• NRC has participated in numerous harvesting programs over the years:

RPV, CROM penetrations, RCS piping, RPV internals, neutron absorbers, and cables From unfinished, operating,and decommissioning plants in U.S. and internationally

• Significant value in using harvested components to confirm data from other research programs

Technical Lessons Learned

• Harvesting can provide highly representative aged materials for research May be only practical source of representative aged materials May be able to use limited harvested materials to validate larger accelerated aging data set

• Important to gain as much information as possible in advance before committing to specific harvesting project

Logistical Lessons Learned

• Harvesting is an expensive, time-consuming effort

• Leveraging resources with other research organizations helps mitigate cost challenges

• Transporting irradiated materials, particularly internationally, is cumbersome and time-consuming Lifting operation for irradiated materials transport cask

Presentation Notes Date: 1/6/2021 9:20:50 AM Harvesting is an expensive, time-consuming effort Must balance cost with potential benefits carefully High technical relevance of materials is needed to ensure value Leveraging resources with other research organizations helps mitigate cost challenges Can introduce challenges for testing when aligning research priorities and interests of multiple organizations May be needed, particularly for expensive testing of irradiated materials Transporting irradiated materials, particularly internationally, is cumbersome and time-consuming Avoiding extra transport, especially between countries, is highly recommended

Ill Recent N RC Activities

• Strategic approach to materials harvesting Due to limited opportunities, past harvesting efforts have generally been reactive to individual plants shutting down

• Prioritize the data needs best addressed by harvesting

• Workshop held in March 2017 at NRC HQ to discuss all aspects of harvesting with other interested stakeholders

Presentation Notes Date: 1/6/2021 9:20:50 AM Strategic approach to materials harvesting Due to limited opportunities, past harvesting efforts have generally been reactive to individual plants shutting down Prioritize the data needs best addressed by harvesting Criteria for harvesting prioritization developed by PNNL Workshop held in March 2017 at NRC HQ to discuss all aspects of harvesting with other interested stakeholders Good discussion of experience, including challenges and pitfalls, from those with firsthand knowledge

Ill Potential Criteria for Harvesting Prioritization

• Applicability of harvested material for addressing critical gaps

• Ease of laboratory replication of the degradation scenario

• Unique field aspects of degradation

• Fleet-wide vs. plant-specific applicability of data

Presentation Notes Date: 1/6/2021 9:20:50 AM Applicability of harvested material for addressing critical gaps Harvesting for critical gaps prioritized over less essential technical gaps Ease of laboratory replication of the degradation scenario For example, simultaneous thermal and irradiation conditions are difficult to replicate Unique field aspects of degradation For example, unusual operating experience or legacy materials (fabrication methods, etc.) no longer available Fleet-wide vs. plant-specific applicability of data

Ill Potential Criteria for Harvesting Prioritization

• Harvesting cost and complexity

• Availability of reliable in-service inspection (ISi) techniques for the material/ component

• Availability of materials for harvesting

• Timeliness of the expected research results relative to the objective

Presentation Notes Date: 1/6/2021 9:20:50 AM Harvesting cost and complexity For example, harvesting unirradiated concrete or electrical cables less expensive and less complex than harvesting from the reactor internals Availability of reliable in-service inspection (ISi) techniques for the material/ component If mature inspection methods exist and are easy to apply, harvesting may be less valuable Availability of materials for harvesting Timeliness of the expected research results relative to the objective

Database for Sources of Materials

• NRC is pursuing the development of a database for sources of materials for harvesting

• Allow for aligning of high-priority data needs to the available sources of materials

• NRC is interested in engaging with other organizations in developing the database Example of reactor internals harvesting plan

Presentation Notes Date: 1/6/2021 9:20:50 AM NRC is pu rsuing the development of a database for sources of materials for harvesting Includes both previously harvested materials and those available for future harvesting Allow for aligning of high-priority data needs to the available sources of materials The level of detail should be appropriate for the factors influencing decision-making NRC is interested in engaging with other organizations in developing the database

Ill Conclusion and Path Forward

• Harvesting can yield highly representative and valuable data on materials aging

• Data Needs Prioritization and Sources of Materials Database

• As specific harvesting opportunities are identified, NRC welcomes opportunities for cooperation and leveraging with other interested research organizations

RE: NRC Staff Attendance at Workshop Harvesting Workshop Agenda 2-23-17.docx No, I think we just got our wires crossed a bit when discussing it on Tuesday. I updated the agenda document (attached) and rearranged session 5. How does this look?

RE: NRC Staff Attendance at Workshop Matt:

I'm still a bit unclear on session 5. Maybe I'm being dense PNNL (for NRC)

Technical Information Needed for Informed Pradeep Ramuhalli Harvesting Decisions EPRI Sherry Bernhoft DOE Rich Reister NRC Robert Tregoning NRC Perspective on Future Harvesting Planning DISCUSSION Action Items and Closing Thoughts

What specifically do we want Sherry and Rich to cover in their remarks? I thought we talked yesterday about EPRI, DOE, and NRC just providing some closing thoughts and then opening it up to the group. I envisioned that the session would look like this

1. Pradeep's talk

2. General Discussion using seeded questions.

3. Summary of action items

4. Closing thoughts about workshop and harvesting in general: first DOE, EPRI, and NRC and then open it up to the group.

While I'm not opposed to the above layout, I just want to make sure that we're clear what we want Sherry and Rich to communicate in their separate talks prior to the discussion.

On another note, I think it would be good to indicate specific times for each talk, especially within session 2 - 4 to reinforce the notion that each speaker only has been allotted that amount of time.

Otherwise, it looks good but I'd really like to get titles © Rob Robert Tregoning Technical Advisor for Materials US Nuclear Regulatory Commission Two White Flint North, M/S T-10 A36 11545 Rockville Pike Rockville, MD 20852-2738 ph: 301-415-2324 fax: 301-415-6671 From: Hiser, Matthew Sent: Wednesday, February 22, 2017 1:27 PM To: Tregoning, Robert <Robert.Tregoning@nrc.gov>; Purtscher, Patrick <Patrick.Purtscher@nrc.gov>

RE: NRC Staff Attendance at Workshop Hi Rob, I've attached the latest workshop attendee and webinar contact list. It's only a few external people. INL will be sending John Jackson who will give a brief talk on the NSUF sample library in session 3. Any other INL staff will participate via webinar.

I haven't heard back from EnBW, so I put together the agenda assuming they will not present. We could easily add them into session 4 if necessary. I've attached the final agenda. Please take a look and let me know what you guys think.

Thanks!

RE: NRC Staff Attendance at Workshop Matt:

Who's on the final webinar list? I think we have like 3 or 4 people correct? Do we have final confirmation that INL will just send one person? I think adding Mark is fine as long as we're right around 30 people.

NRC Staff Attendance at Workshop Pat Purtscher NRC Rob Tregoning NRC Matt Hiser NRC Mita Sircar NRC NRC Tom Koshy NRC NRR/DE NRC NRR/DLR NRC NRR concrete NRC Hi Rob and Pat,

This is the current list of NRC staff attending the workshop. Tom Koshy indicated a NRR electrical wouldn't be needed (or if NRR sent an electrical person then Tom wouldn't be needed), so I haven't included them on here. With these 8 NRC staff plus 23 external participants, we are at 31 total.

The other person that I have discussed this workshop with that has expressed strong interest in attending is Mark Kirk. Given the Belgian participation and interest in RPV topics, we might want to allow him to attend as well. That would put us at 32 total in the room. Thoughts?

Thanks!

Matt
