Advanced Manufacturing Methods NEI Roadmap on Regulatory Acceptance March 13, 2019

©2018 Nuclear Energy Institute

Goal of NEIs Roadmap Challenge: Advanced manufacturing methods rapidly maturing for use by nuclear industry; however, a timely and clear pathway to regulatory acceptance remains an obstacle for many methods Objectives:

1. Identify the methods of most interest to industry - biggest benefits and nearest-term use

2. Provide insight to organizations assignment of resources toward furthering the commercialization of methods

3. Establish clarity on an expedited pathway to regulatory acceptance

Survey Results sortable by organization type (e.g., developer, manufacturer)

Understand interest

• Desired benefits (e.g., reduce cost, improved quality)

• Applications (e.g., radiation environment, non-water coolant)

• Types of components (e.g., vessels, pumps, fuel assembly)

• Concerns (e.g., lack of qualification data, standards development)

Identify for all methods

• Importance based on potential benefits and scope of applicability

• Urgency based on desired timeframe for using method

Regulatory Acceptance Pathways Current: NRC rulemaking to accept ASME code Challenge: Can take ASME years to incorporate into code, and then the NRC another few years to accept ASME code Proposed expedited pathways to accelerate NRC acceptance

• Application (e.g., topical report, license amendment) includes method qualification and component qualification data

• Two ways to provide method qualification data

1. NRC adoption of ASME code case (e.g., interim staff guidance)

2. Provided by applicant

• Expected content of application (e.g., functions, environment, properties, performance, quality/repeatability, )
