Advanced Methods in Manufacturing:
Additive Manufacturing for Reactor Components Office of Nuclear Regulatory Research, Division of Engineering, Corrosion & Metallurgy Branch and Office of New Reactors, Division of Construction Inspection and Operational Programs, Quality Assurance Vendor Inspection Branch B Industry/NRC Materials Programs Technical Information Exchange, May 23, 2018
Overview: Why Additive Manufacturing for Reactor Components?
- RES Objective: Anticipatory review to allow NRC to be ready to assess adequacy of AM parts in NPPs - AM applications possible in 2018/2019.
- Driver/Applications: Provide critical jumpstart to ascertain NRC is ready for industry requests including direct metal laser melting (DMLM/AM).
- Prospective Collaboration: DOE, EPRI, NIST, ASTM, NASA, FAA, DOD DMLM Process Demonstration Specimen at GE Power Advanced Manufacturing Works, Greenville, SC, C.

Engage with Industry to be informed about potential applications NRC Workshop on Vendor Oversight NRC Standards Forum, Sept. 2018 RIS 2017-08 currently under revision to include AM-related questions:
- 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?
Coordinating with other regulators NRC interest areas
- Reliability of AM processing and quality of AM parts
- Properties of AM parts
- Structural performance of AM parts, including their inspectability
- Service performance and aging degradation of AM parts
- Codes & standards development for AM M. Gorelik, Regulatory Considerations for AM and Status of the FAA AM Roadmap, Nov. 28, 2017
