Advanced Manufacturing Technologies
- Action Plan Status -
Industry/NRC Materials Technical Exchange Meeting NRC Headquarters, Rockville, MD May 22, 2019 United States Nuclear Regulatory Commission Office of Nuclear Reactor Regulation Division of Materials and License Renewal Allen Hiser, Christopher Hovanec, David Rudland
2 Key Messages Efficient and effective disposition of advanced manufacturing technology (AMT) proposals Current regulatory framework is sufficient for AMTs Reasonable assurance of adequate protection based on performance criteria and safety significance Early communication/coordination with stakeholders
3 NRC, Transformation, & AMTs Transformation Initiative & Staff Guidance:
AMTs are becoming increasingly applicable to the U.S. nuclear industry and the NRC Mission
- Realize marked enhancements in NRC effectiveness, efficiency, & agility
- New materials & manufacturing approaches
- Actively identify, encourage, & implement innovation and transformation to advance the NRC mission
- Emphasis on proactive posture for new technologies
4 Advanced Manufacturing Technologies Techniques and material processing methods that have not been:
- traditionally used in the United States nuclear industry
- formally standardized/codified by the nuclear industry AMT Action Plan (ADAMS ML18347B158) Objective:
Proactively position the NRC for an efficient, effective, &
transparent regulatory review of licensee use of AMTs
5 Proactive Posture Mid 2017 November 2017 NRC Workshop on Additive Manufacturing December 2018 U.S. Department of Energy Advanced Manufacturing for Nuclear Workshop and Program Review January 2019 NRC Action Plan for AMTs February 2019 Public Meeting &
Guiding Principles April 2019 Candidate AMT Application,
Near-term Activities, &
External Interaction Plan Limited-scope effort focused on additive manufacturing Transformation guidance to NRC staff Continued Engagement
6 AMT Action Plan Five major tasks outlined over the next 12 months Task 5: Update Action Plan Task 4: Knowledge Management Task 1: Near-Term (~6 months)
Public meetings / communication Memo identifying candidate AMT Develop resource for review of 50.59 Task 2: Continuing Activities Continue/update select activities from Task 1 Develop plan for external interactions Develop generic technical guidance for AMT submittals Task 3: NRC Guidance Review NRC guidance and determine if updates/revisions are needed Memo recommending a path forward on guidance development or modification
7 AMT Regulatory Paths Nonregulated Application 10 CFR 50.59 Changes, Tests and Experiments.
10 CFR 50.55a Codes and Standards (C&S) 10 CFR 50.55a(z)
Alternatives to C&S Requirements
8 Candidate AMT Application Thimble Plugging Device:
Additive manufacturing SS 316L (wrought 304 SS)
Non-Code class Reactor water environment 10 CFR 50.59 Estimate ~6 months Perceived industry ranking of AMTs:
- 1. Laser Powder Bed Fusion (LPBF)
- 2. Powder Metallurgy - Hot Isostatic Pressing (PM-HIP)
- 3. Electron Beam (EB) Welding
9 NRC Review & Implementation Assumptions: (1) Quality assurance & current requirements satisfied, (2) AMT not codified Code class component Non-Code class, Safety-related Non-safety-related, Non-regulated Alternatives to C&S 10 CFR 50.55(a)(z)
Changes, tests
& experiments 10 CFR 50.59 Maintenance Rule 50.65(a)(4) and/or applicable process NRC Review Implement Activity
- Generic, simplified applicability of the 10 CFR 50.59 process. Actual regulatory path will be both plant-specific and application-specific. **
10 Future Public Meetings Planned:
Sept. 2019 - Generic technical information needed in AMT submittals Potential:
AMT Action Plan, Revision 1 NRC workshop / status meeting 10 CFR 50.59 applicability & unforeseen challenges Clarification, modification, and development of NRC guidance documents For Implementation of AMT:
At stakeholders request Future and/or candidate applications
11 Path Forward Maintain alignment with the NRC Transformation Initiative Execute & maintain the Action Plan Adhere to the Guiding Principles Continue communication and transparency with stakeholders
