Action Plan for Advanced Manufacturing Technologies (AMTs)
Public Meeting - Category 2 NRC Headquarters, Rockville, MD February 07, 2019 United States Nuclear Regulatory Commission Office of Nuclear Reactor Regulation Division of Materials and License Renewal Presented by:
Christopher Hovanec, Ph.D.
2 Overview Key Messages Meeting Objectives AMT Action Plan Information Needed
3 Key Messages
- 1. The NRC is receptive to reviewing emergent technologies and intends to efficiently and effectively disposition proposals from licensees involving AMTs
- 2. The current regulatory framework is sufficient for AMTs; although, staff will seek to find efficiencies in processes were appropriate
- 3. Reasonable assurance of adequate protection will be based on performance criteria, and safety significance
- 4. Early communication/coordination between the NRC, licensees, OEMs, industry groups, DOE, and stakeholders is critically important to ensure an efficient and effective review
4 Meeting Objectives
- 1. Solicited feedback/comments from stakeholders to inform the execution and/or revision of the Action Plan
- 2. Gain insight into licensees intent to field AMTs:
- AMT method
- Alloy
- Component
- Intended regulatory path
- Time frame
5 Advanced Manufacturing Technologies Techniques and material processing methods that have not been:
- traditionally used in the United States nuclear industry
- formally standardized by the nuclear industry (e.g., nuclear codes and standards, or other processes resulting in NRC approval/endorsement)
6 AMT Action Plan (1)
Purpose:
- Initiate the development of a strategy that will address the items in the EDO memo [1] & SECY-18-0060 [2]
- Proactively position the NRC for an efficient, effective, &
transparent regulatory review of expected licensee use of AMT
[1] Memorandum from V.M. McCree to all NRC Staff, Innovation and Transformation at the NRC, ADAMS Accession No. ML18004A021, January 4, 2018
[2] SECY-18-0060, Achieving Modern Risk-Informed Regulation, ADAMS Accession No. ML18110A186, May 23, 2018 Objectives:
- Identify AMTs most likely to be used for nuclear hardware
- Prepare NRC staff to review submittals
- Identify and address AMT characteristics pertinent to safety
- Provide guidance and tools for review consistency, communication, and knowledge management
- Provide transparency to stakeholders
7 AMT Action Plan (2)
Action Plan Characteristics:
- Technology neutral
- Performance-based
- Safety and reliability focused
- No new regulations or processes
- Forward looking
- Living document High-Level Review Consideration:
Design & Performance Materials & Process Demonstration & Data In-service (degradation & Inspectability)
8 Major Tasks (1)
Five major Tasks outlined for the next ~12 months Task 1: Near-Term Needs Task 2: Continuing Needs Task 3: Determine if updated or new guidance is necessary Task 4: Knowledge management Task 5: Update Action Plan Task 1: Near-Term (~6 months)
- Public meeting
- Near-term communication/interactions
- Memo identifying a candidate AMT and component
- Information gathering on candidate AMT
- Develop technical/safety document for candidate AMT
- Develop briefing materials for review of 50.59
9 Major Tasks (2)
Task 2: Continuing Continue/update select activities from Task 1 Develop external interaction plan to leverage knowledgebase Develop generic technical staff resource for AMT reviews Conduct public meeting to discuss content of staff resource Task 3: NRC Guidance Review NRC guidance and determine if updates or revisions are needed Develop a memo recommending a path forward on guidance development or modification Task 4: Knowledge Management Develop a Knowledge management plan Task 5: Update Action Plan Evaluate the need to update plan and revise accordingly
10 Regulatory Paths
- NRC review is not required
- Experience can inform regulated applications Non-Regulated Application
- Licensee determines that NRC review/approval is not required
- Regional staff review the implementation of the 50.59 process 10 CFR 50.59 Process
- NRC is a voting member for ASME Code
- Endorsed: Regulatory Guides &/or incorporated by reference 10 CFR 50.55a - Codes and Standards (C&S)
- Generic topical reports or plant specific submittals
- NRC review/approval is required 10 CFR 50.55a(z) - Alternatives to C&S Requirements
11 Information Needed Application-specific
- AMT method
- Alloy
- Component
- Intended regulatory path
- Time frame Candidate Application Additive manufacturing SS 316L Non-Code Class Reactor water environment 10 CFR 50.59
~6 months Near-term tasks focused on assumed initial AMT
