Regulatory Perspectives on Advanced Manufacturing Technology Allen Hiser, Christopher Hovanec, David Rudland U.S. Nuclear Regulatory Commission Office of Nuclear Reactor Regulation Division of Materials and License Renewal Regulatory Information Conference W22Use of Advanced Manufacturing for Power Reactors March 13, 2019
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 2
Advanced Manufacturing Technologies Techniques and material processing methods that have not been:
- Traditionally used in the U.S. nuclear industry
- Formally standardized/codified by the nuclear industry Examples:
- Additive manufacturing
- Powder metallurgy, hot isostatic processing (PM-HIP)
- Electron beam welding
- Coating/cladding methods Credit: Beamie Young\NIST 3
Anticipated Deployment AMTs are becoming increasingly applicable to the U.S.
nuclear industry and the U.S. Nuclear Regulatory Commission (NRC) mission:
- Foreign nuclear plants
- Aerospace, U.S. Department of Defense, and industries with high-reliability needs
- Significant resources expended 108mm diameter impeller and demonstration parts fabricated Krko NPP, Slovenia Credit: Siemens Technology development and possible implementation are moving rapidly, and the agency seeks to proactively position itself to respond appropriately 4
Transformation and AMTs NRC Transformation Initiative
- Realize marked enhancements in NRC effectiveness, efficiency, and agility
- New materials and manufacturing approaches
- Actively identify, encourage, and implement innovation and transformation to advance the NRC mission
- Emphasis on proactive posture for new technologies 5
AMT Regulatory Paths 10 CFR 50.59 Nonregulated Changes, Tests and Application Experiments.
10 CFR 50.55a 10 CFR 50.55a(z)
Codes and Alternatives to C&S Standards (C&S) Requirements 6
Proactive Posture Mid 2017 Limited-scope effort focused on additive manufacturing November NRC Workshop on Additive Transformation 2017 Manufacturing guidance to NRC staff December U.S. Department of Energy Advanced Manufacturing for Nuclear Workshop 2018 and Program Review January NRC Action Plan for AMTs 2019 February Public Meeting and 2019 Guiding Principles Continued TBD 2019 Follow-on Engagement Public Meeting(s) 7
Lessons Learned Efficient reviews:
- Early communication and precoordination
- Quality and completeness of applications/submittals
- Staff knowledge of topic prior to submittal:
- General technical aspects
- Technology meets (or fails to meet) the consensus C&S and/or regulations
- Past research and ability to conduct appropriate confirmatory research Emphasis on activities that occur prior to a formal submittal/request 8
AMT Working Group
Purpose:
- Initiate a strategyAMT Action Plan
- Proactively position for an efficient, effective, and transparent regulatory evaluation of expected licensee use of AMT Guiding Principles Safety Regulatory Adaptable Focused Stability Performance Technology Transparent Based Neutral 9
AMT Action Plan Five major tasks outlined over the next 12 months Task 3: NRC Guidance Task 1: Near-Term (~6 months)
Task 4: Knowledge Management Task 2: Continuing Activities Task 5: Periodically Update Action Plan 10
Future Public Meetings Planned:
- September 2019Generic technical information needed in AMT submittals Potential:
- October 2019Clarification, modification, and development of guidance documents
- TBDNRC workshop / status meeting For Implementation of AMT:
- At stakeholders request
- Future and/or candidate applications 11
Candidate Application Thimble Plugging Device:
- Additive manufacturing
- Non-American Society of Mechanical Engineers Boiler and Pressure Vessel Code class
- Reactor water environment
- Title 10 of the Code of Federal Regulations (10 CFR) 50.59
- Estimate ~6 months 12
Path Forward
- Maintain alignment with the NRC Transformation Initiative
- Execute and maintain the Action Plan
- Adhere to the agencys Guiding Principles
- Continue communication and transparency with stakeholders 13
Thank You 14
