• Techniques and material processing methods

- Not traditionally used in the U.S.

nuclear industry

- Not formally Advanced standardized/codified by the Manufacturing nuclear industry

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

6 Technical Preparedness

• NDE confirmatory efforts on AMT components, mock-ups, welds

• Assessment of additional technologies: Arc --DED and diode laser cladding NRC

• Evaluation of long-term performance, including environmental effects (e. g., irradiation, corrosion)

Ongoing and User Need Participation in ASME Code activities Request Activities Communications and KM:

NRC NDE of AMT Technical Exchange: May 2023 NRC AMT Workshop: October 2023 7

• Additional Technical Assessments

- Arc Directed Energy Deposition

• NDE of AMT Components UNR Tasks - - Mock-ups and evaluation

• Data and Modeling for Technical Qualification Preparedness - In-process monitoring

- Digital data characterization

• Materials Performance of AMT Components
