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.
