June 14-15, 2023

• 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

• Non ASME B&PV Code class

• Non ASME B&PV Code class

• Research

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

• Assessment of additional NRC Activities - technologies: A rc --DED and diode laser cladding Moving For ward

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

irradiation, corrosion)

• Participation in ASME Code activities

• NRC AMT Workshop: October 24-26, 2023
