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:
  • 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
  • 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

  • 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
