Review of Additive Manufacturing for Reactor Materials & Components Office of Nuclear Regulatory Research NRC Workshop on Vendor Oversight, June 14, 2018 Amy B. Hull Sr. Materials Engineer, Office of Nuclear Regulatory Research, Division of Engineering, Corrosion & Metallurgy Branch
Introduction. Why Additive Manufacturing (AM) for Reactors?
2
Regulatory Research Perspective Objective of NRC Engagement AM is Not a Single Process
- A partial list of metal AM technologies
- Industry, agency, and society collaboration is needed to ensure safe introduction of AM in major industry sectors
Overview
- 1. Stimulus of June 7, 2017 GE-H meeting with NRC
- 2. ANSI AMSC Activities & Phase II Meetings
- 3. Advanced Manufacturing & Supply Chain Innovation Nuclear Energy Leadership Summit &
Industry Showcase and DOE-NE AMM Program Review (Oct 3-5 -- Idaho Falls)
- 4. Visit to WEC Churchill Laboratories to discuss direct metal laser melting (DMLM) irradiation and fabrication (Pittsburgh)
- 6. NRC/Industry Additive Manufacturing Technical Information Exchange, Nov 28-29
- 7. Visits to Advanced Manufacturing facilities
- 8. Ongoing Activities
- 9. Path Forward 6
Engage with Other Organizations to Understand Expertise and Resources Public meeting Additive Materials for Reactor Materials and Components
- Standardization activities
- AM research and applications in nuclear and other industry
- AM processes and capabilities
- Technical and regulatory challenges.

NRC Action Plan Early stages of development To address preparation of NRC readiness for review of AM parts Provide for interoffice coordination - reactor side, waste management, research Address involvement in standards and codes organizations A subject of NRC Innovation and Transformation initiative 10
NRC Regulatory Information Summary RIS 2017-08 under revision to address AM plans and schedules for fabrication of large components and modules (Including nontraditional or advanced manufacturing methods, such as additive manufacturing, cryogenic machining, and Powder metallurgy-HIP)
Are you considering using nontraditional or advanced methods of manufacturing (e.g., additive manufacturing (AM, 3-D printing), powder metallurgy-hot isostatic pressing, electron beam welding, etc.)
for reactor internals, fuel, or component subject to the Appendix B Program at any stage of their lifecycle?
If so, what materials, components, and manufacturing technologies are you considering?
What is the estimated time frame for putting a component into service that used a nontraditional or advanced fabrication method?
11
Summary
- Advanced manufacturing has been identified as an area of potential future utilization by the nuclear industry - when and how many are the questions
- NRC interest areas
- The reliability of AM processing and quality of AM parts
- The properties of AM parts
- The structural performance of AM parts, including their inspectability
- The service performance and aging degradation of AM parts
- Ongoing work in advanced methods for manufacturing.
- Codes and standards aspects of AM is a key to successful implementation
- Comparison of performance of parts from AM and conventional manufacturing process (benchmarking)
- NRC advanced manufacturing action plan under development
- Upcoming RIS may have questions pertaining to AMM 12
