Ex-plant Materials Harvesting Workshop Presentations

Dear Harvesting Workshop Presenters:

If you are receiving this emai l, 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 hop ing 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 ta ilor your presentation to the focus and length of the respective session .

There are two actions I request from presenters:

1. 1have attached the confirmed list of speake rs in an Excel document. Please take a look at this list to confi rm you are presenting in the session you expected and if I have made any m ista kes 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:

ht tps ://drive .google.com/drive/fo lders/0BSDWMLchSYSXcnpZZ0JOS0SSOUU?usp=sharing\

by the end of February if possible .

Than k yo u for your participation in t he workshop. We are looking forward to t he discu ss ion and engagement and appreciate your contrib ut ion to a prod uctive and interesting meeting !

U .S . DEPARTM NT OF ENERGY Nuclear Energy Light Water Reactor Sustainability (LWRS)

Program - Perspectives on Material Harvesting Ex-Plant Materials Harvesting Workshop Richard Reister Office of Light Water Reactor Deployment Office of Nuclear Energy U.S. Department of Energy March 7-8, 2017

U.S. DEPARTMENT OF ENERGY Light Water Reactor Nuclear Energy Sustainability (LWRS) Program LWRS Program Goal

  • Develop fundamental scientific basis to allow continued long-term safe operation of existing LWRs (beyond 60 years) and their long-term economic viability LWRS program is developing technologies and other solutions to
  • Enable long term operation of the existing nuclear power plants
  • Improve reliability
  • Sustain safety LWRS focus areas
  • Materials Aging and Degradation
  • Advanced Instrumentation and Controls
  • Risk-Informed Safety Margin Characterization Nine Mile Point - Courtesy Constellation Energy
  • Reactor Safety Technologies 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

  • 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 Advantages of service-aged Nuclear Energy 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 Zion Unit 1 Containment Cables Nuclear Energy 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 Zion Records Harvested from Nuclear Energy 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 Electrical Components for the US Nuclear Energy 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.

9

U.S. DEPARTMENT OF ENERGY Zion Cables Part 2 Nuclear Energy (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.~~~;

11

U.S. DEPARTMENT OF ENERGY Ginna Baffle Former Nuclear Energy 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).

12

U.S. DEPARTMENT OF l&C cables from Crystal River ENERGY 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 Jose Cabrera (Zorita) NPS sample storage and further examinations 14
