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.
