Advanced Manufacturing Technologies

  • Techniques and material processing methods

- Not traditionally used in the U.S. nuclear industry

- Not formally standardized/codified by the nuclear industry

- AMTs can include new ways to fabricate or join components, surface treatments, or other processing techniques to provide a performance or operational benefit.

NRC Activities -

Moving Forward

  • Research
  • NDE confirmatory efforts on AMT components, mock-ups, welds
  • Assessment of additional technologies: Arc--DED and diode laser cladding
  • Evaluation of long-term performance, including environmental effects (e.g.,

irradiation, corrosion)

  • Participation in ASME Code activities
  • NRC AMT Workshop: October 24-26, 2023 6
