  • Techniques and material processing methods

- Not traditionally used in the U.S. nuclear industry Advanced - Not formally Manufacturing standardized/codified by the nuclear industry Technologies - AMTs can include new ways to fabricate or join components, surface treatments, or other processing techniques to provide a performance or operational benefit.

2 Examples of U.S. Applications installed under 10 CFR 50.59

Thimble Plug ging Device Channel Fastener

  • Byron Unit 1
  • Browns Ferry Unit 2
  • 316L stainless steel - LPBF* 316L stainless steel - LPBF

  • Technical Preparedness NRC s initial focus areas Technical Letter Reports (National Laboratories) Laser powder bed fusion NRC Technical Assessments (LPBF)

Laser direct energy

  • Regulatory Preparedness deposition (L-DED)

Draft Guidelines Documents - technology specific Cold spray (CS)

Draft Review Guidelines - generic Electron beam welding Implementation Using the 50.59 Process for AMTs (EBW)

  • Communications and Knowledge Management Power metallurgyhot Engagement with industry, codes & standards, isostatic pressing (PM-HIP) research organizations, international *new reactor fuel technologies Staff development are addressed outside the AMT Action Plan
