©2018 Nuclear Energy Institute 2Challenge: Advanced manufacturing methods rapidly maturing for use by nuclear industry; however, a timely and clear pathway to regulatory acceptance remains an obstacle for many methodsObjectives:

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 Goal of NEI's Roadmap

• 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 methodSurvey

©2018 Nuclear Energy Institute 6Current: NRC rulemaking to accept ASME codeChallenge: Can take ASME years to incorporate into code, and then the NRC another few years to accept ASME codeProposed 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 , )Regulatory Acceptance Pathways
