RE: Ex-plant Materia Is Harvesting Workshop Presentations
Dear Presenters:
Thank you for sending presentation titles. I have all but a couple at this point and have attached the updated agenda.
I know many of you are working on fina lizing you r slides for t he workshop (I already have 2 su bmitted as of today !). Please provide slides by Friday if al al l possible. It will be very cha llengi ng to load presentations onto the computer via thumb drive the day of the workshop due to NRC computer security restrictions, so sending them in advance is greatly preferred. Aga in, best options for sending are either email or upload to Google Drive:
https://dr1ye.google.com/dr1ve/folders/0BSDWMLch5YSXcnpZZ0JOS055OUU?usp=sharing.
I am looking forward to a productive workshop next week and appreciate your participation. Please let me know if you have any questions or suggestions for the workshop.
Thanks!

Ex-plant Materials Harvesting Workshop Presentations
Dear Harvesting Workshop Presenters:
If you are receiving this email, then I have you down on the agenda to present at the upcoming Ex-plant Materials Harvesting Workshop on March 7-8. I have attached the workshop introduction slides that have been shared with most, if not all, of you. These slides cover meeting logistics, motivation, approach, expected outcome, and session expectations. We are hoping these slides provide a common vision for the workshop that will allow for a focused, productive discussion.
Please take a look at these slides and try to tailor your presentation to the focus and length of the respective session.
There are two actions I request from presenters:
- 1. 1 have attached the confirmed list of speakers in an Excel document. Please take a look at this list to confirm you are presenting in the session you expected and if I have made any mistakes in the list of speakers. If you have not already done so, please provide me w ith a presentation title.
- 2. Please send me your slides (either via email or upload to Google Drive:
https://drive.google.com/drive/folders/0BSDWMLchSYSXcnpZZ0JOS0SSOUU?usp=sharing\\
by the end of February if possible.
Thank you for your participation in t he workshop. We are looking forward to the discussion and engagement and appreciate your contribution to a productive and interesting meeting!
Thanks!

- Enable long term operation of the existing nuclear power plants
- Improve reliability
- Sustain safety L WRS focus areas
- Materials Aging and Degradation
- Advanced Instrumentation and Controls
- Risk-Informed Safety Margin Characterization
- Reactor Safety Technologies Nine Mile Point - Courtesy Constellation Energy 2
U.S. DEPARTMENT OF ENERGY Materials Aging and Degradation Nuclear Energy Metals: including Reactor Pressure Vessels, core internals, steam generators, and balance of plant
- Irradiation-Assisted Stress Corrosion Cracking
- High-fluence phase transformations and swelling of core internals
- High-fluence effects on RPV steel
- Crack initiation in Nickel based alloys
- Thermal Aging of Cast Austenitic Stainless Steels
- Environmentally Assisted Fatigue Concrete: Joint research plan with EPRI focused on radiation effects (supports and biological shield) and monitoring tools Cables: Joint research plan with EPRI and NRC to better predict and monitor cable aging Mitigation, repair, and replacement technologies: Weld repair techniques; Post irradiation annealing; Advanced replacement alloys; and Advanced Non-Destructive Examination techniques 3
U.S. DEPARTMENT OF ENERGY Nuclear Energy Advantages of service-aged materials
- Fills knowledge gaps when there is limited operational data or experience Informs current degradation models The LWRS Program has ongoing or potential activities at:
Zion Ginna and Nine Mile Point Plants Crystal River 3: EPRI led effort in collaboration with LWRS and NRC (Cables)
Zorita: NRC led effort to obtain concrete cores from the biological shield. Testing at ORNL with possible LWRS support 4
U.S. DEPARTMENT OF ENERGY Difficulties and Limitations Nuclear Energy High cost High costs lead to multiparty cooperation to spread costs which adds to complexities Scheduling difficulties (both with decommissioning companies and operating plants)
Getting sufficient material pedigree Potentially limited research value (cost/benefit)
Limited opportunities Potential negative results could impact operating plants Difficult logistics
- Contracting
- Final disposition and disposal
- Liability
- Shipping 5
U.S. DEPARTMENT OF ENERGY Zion Coordination Nuclear Energy In support of extended service (and current operations), ORNL coordinated and contracted activities with Zion Solutions (Energy Solutions).
In collaboration with the US NRC, EPRI, and others, a list of materials for "harvesting" has been compiled and feasibility examined.
- Structures and components of interest:
- Thru-wall RPV sections
- Cabling
- Concrete bore samples
- Access to stored fuel containment
U.S. DEPARTMENT OF ENERGY Nuclear Energy Zion Unit 1 Containment Cables acquired in the Spring 2012 Harvested 6 sets of cables, ~ 25' in length, and each containing two cable types - CRDM DC power and position indicator. Also harvested 8 thermocouple cables identified during 2011 containment tour.
The LWRS Program and NRC are studying cables harvested from Zion to understand and predict cable degradation at extended lifetimes.
7
U.S. DEPARTMENT OF ENERGY Nuclear Energy Zion Records Harvested from Vault 2013 Zion Records: The acquisition of key records provides critical information about the initial materials properties, in service inspection, and operational history necessary to evaluate the degradation of materials.
8
U.S. DEPARTMENT OF Zion Harvesting 2013:
ENERGY Nuclear Energy Electrical Components for the US NRC Zion Electrical Components: During February 25, 2013, site visit, the NRG identified an L shaped bus bar that was harvested in 2013 for fire protection testing.

U.S. DEPARTMENT OF ENERGY Nuclear Energy Zion Cables Part 2 (2013-2017)
Harvested Zion Unit 2 low and medium voltage cables in collaboration with the NRC
- Accumulator Discharge MOV Cabling
- Instrumentation Cables
- Air-Operated Valve Cabling
- Cables in Electrical Penetrations ~

U.S. DEPARTMENT OF ENERGY Zion Unit-1 RPV Harvesting Nuclear Energy 2014-2017
- Two panel sections, ~14 tons each, were harvested in November 2015, cut into blocks and are now in the process of being machined into > 1,000 individual test specimens
- Goal of research:
Evaluation of radiation damage models Comparison to surveillance and high flux reactor experiments Attenuation and through wall variation in base and weld metal.
Mitigation techniques - annealing / re-irradiation studies.
WF-70, Belt-line Weld --w.~~~;

U.S. DEPARTMENT OF ENERGY Nuclear Energy Ginna Baffle Former Bolts
- Retrieval of bolts end of August 2016
- Post-service/irradiation evaluation of high fluence bolts that were withdrawn from service in 2011 from R.E. Ginna (2-loop down flow).
- Alloy 347, irradiation profiles spanning 15 to 42 dpa (variation of fluence along bolts with overlap between the two bolts - same fluence, different temperatures).
- Fracture toughness/ fatigue crack growth testing, microstructural examinations, and Stress Corrosion Cracking (SCC) testing.
12
U.S. DEPARTMENT OF ENERGY l&C cables from Crystal River and Zion Nuclear Energy Harvested l&C cables play a critical role in developing models to quantify the influence of environmental degradation and develop practical NDE techniques In collaboration with EPRI & NRC in 2016, over 5,000 feet of l&C cable outside of containment from Zion and Crystal River have been harvested and environmental degradation studies on highest priority materials has begun
U.S. DEPARTMENT OF ENERGY Zorita Concrete Nuclear Energy Harvesting concrete cores from reactor cavities of plants undergoing decommissioning will yield material that has experienced typical LWR radiation fields NRC led effort ORNL as contractor Possible DOE support for sample storage and further examinations Jose Cabrera (Zorita) NPS 14
