NRC AMT Public Website Contains AMT-related documents and information
M ay 2-3, 2023, NDE of AMT Technical Exchange 5 NRC Perspective on AMT in US Nuclear Industr y
- Regulatory review preparations highly depend on awareness of industry interests, developments and advances
- A couple of parts have been introduced into US plants using the 50.59 process
- AMTrelated components in the current US Ls do not appear to be a high priority for safetyWR fleet
- Potential interest for SMR and advanced reactors
- Codes and standards development is a key enabler
- Limited data is a challenge, esp. environmentaleffects (corrosion, irradiation)
- Effective and reliable NDE is critical to qualify andmonitor the integrity of AMT components NRC Chair - visit to Advanced Manufacturing Pilot
Facility at Georgia Tech
- International developments:
L-DED fabrication of a 3 class 1 valve - Ko re a Installation of AM water impeller - Slovenia
M ay 2-3, 2023, NDE of AMT Technical Exchange 6 Current Regulator y Pathways Least likely
- Rulemaking
- License amendment (technical specification change, etc )
- 10 CFR 50.59 Changes, tests and experiments Subtask 2A of AMT Action Plan, Rev 1 One component installed via this method
- 10 CFR 50.55a Codes and Standards Most likely Endorsement of Code edition and Code cases on AMTs (z) alternatives to codes and standards
M ay 2-3, 2023, NDE of AMT Technical Exchange 7 Ongoing Staff Codes and Standards Activities
- ASME Special Committee on Use of Additive Manufacturing for Pressure Retaining Equipment Developed criteria qualification document for LPBF - ASME PTB-13 - plans to add DED 316L LPBF Data Package and Code Case under development Arc DED Data Package and Code Case under development - multiple materials
- ASME Section III WG on AM (MF&E) Working Group on Advanced Manufacturing Developing rules for fabrication of AM items, including support of AM Code Cases and new Section III Appendix for materials produced by AM processes
Process groups: PM/HIP, DED, QA Requirements
- ASME Section III, Division 5 Task Group on AM for High Temperature Applications Developing Code actions for incorporating AM materials/components in ASME Section III, Division 5 (high temperature reactors) for elevated temperature nuclear construction
First application is PM-HIP
M ay 2-3, 2023, NDE of AMT Technical Exchange 8 NDE Gap Assessment
- Sur vey of Pre-Ser vice and In -Ser vice Nondestructive Evaluation Techniques of AMT-Fabricated Components (ML20349A012)
- Literature search and gap analysis applicable to the NDE of AMT components with an emphasis on methodologies used in the nuclear industry.
- 21 gaps were identified and ranked as High, Medium, or Low Priority based on anticipated needs for pre-service and in-service NDE.
- PNNL identified eight High Priority gaps to address key questions:
- 1. What flaws need to be found?
- 2. What sections of the component volume should be inspected?
- 3. How will the critical flaws be identified?
M ay 2-3, 2023, NDE of AMT Technical Exchange 9 High Priority NDE Gaps - PNNL TLR
- 1. Identification of expected flaws and characteristics
- 2. Defect acceptance standards
- 3. Determination of applicable NDE methods
- 4. Validation of NDE techniques with destructive testing
- 6. Definitions of the relevant inspection volume
- 7. Required level of component surface finish
- 8. Size limitations for inspection of large components
M ay 2-3, 2023, NDE of AMT Technical Exchange 10 PNNL High Priority Gap Detail
M ay 2-3, 2023, NDE of AMT Technical Exchange 11 NRC Activities - Moving For ward
- Research tasks include:
- Assessment of 2 additional AMTs: Arc DED and diode laser cladding
- Long-term performance, environments (i.e., irradiation, corrosion, etc )
- NRC AMT Workshop: Oct. 2023
- Continue NRC participation in ASME Code activities
- Continue NRC involvement in AM standardization efforts
- Possible collaboration leading to share of mockups and test results.
