Advanced Manufacturing Technologies

- Action Plan Status -

Allen Hiser, Christopher Hovanec, David Rudland United States Nuclear Regulatory Commission Office of Nuclear Reactor Regulation Division of Materials and License Renewal Industry/NRC Materials Technical Exchange Meeting NRC Headquarters, Rockville, MD May 22, 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

NRC, Transformation, & AMTs Transformation Initiative & Staff Guidance:

• 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 AMTs are becoming increasingly applicable to the U.S. nuclear industry and the NRC Mission 3

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 4

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 &

2019 Guiding Principles Continued Candidate AMT Application ,

April 2019 Near-term Activities, &

Engagement External Interaction Plan 5

AMT Action Plan Five major tasks outlined over the next 12 months Task 1: Near-Term (~6 months) Task 4: Knowledge Management

• Public meetings / communication

• Memo identifying candidate AMT

• Develop resource for review of 50.59 Task 5: Update Action Plan 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 6

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 7

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 8

NRC Review & Implementation Assumptions: (1) Quality assurance & current requirements satisfied, (2) AMT not codified Code class Alternatives to C&S component 10 CFR 50.55(a)(z)

NRC Review Changes, tests Non-Code class,

& experiments Safety-related 10 CFR 50.59 Implement Activity Maintenance Rule Non-safety-related, 50.65(a)(4) and/or Non-regulated applicable process 9 ** Generic, simplified applicability of the 10 CFR 50.59 process. Actual regulatory path will be both plant-specific and application-specific. **

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 10

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 11

Thank You 12
