Nuclear Innovation Alliance Part 53 Comments 9 December 2021 NRC Commissioner Briefing on Part 53 Rule Development Dr. Patrick White pwhite@nuclearinnovationalliance.org 1

NIA focuses on NRC licensing modernization activities to enable advanced nuclear energy as a climate solution

• Nuclear Innovation Alliance (NIA) is a leading think-and-do tank focused on achieving the conditions for success for advanced reactors so they can be part of the climate solution.

• Deeply engaged with the advanced reactor community as well as the broader energy and climate community.

• NIAs core strengths:

Stakeholder Independent, Strong track Thought Analysis Advocacy collaboration non-partisan record leadership 2

NIA engages with other clean energy NGO stakeholders to inform comments and find common ground Part 53 Industry Public Group Meetings Insights NGO NIA Part 53 Developer Coordination Regulatory Regulatory Calls Strategy Discussions Industry NRC Staff Innovation & Leadership Council Engagement 3

Development of nuclear regulatory frameworks is an inherently iterative process General Design Probabilistic Beyond Design Criteria Analyses Basis Safety Siting Design Basis Operational Requirements Analyses Safety Risk-informed, Expert review performance-based based regulation regulation 4

Part 53 should enable both evolutionary and innovative approaches to regulation Regulatory paradigms

• Regulatory requirements

• Analysis methods

• Regulatory assumptions

• Reactor design criteria

• Probabilistic assessments Westinghouse AP1000

• Organizational programs Oklo Aurora 1120 MWe

• Operational requirements 1 MWe Water Cooled

• Equipment qualification Heat Pipe Cooled

• Reactor siting Evolutionary Regulation Innovative Regulation?

Part 53 regulations can balance certainty and flexibility across multiple characteristics Technology Single Technology Any Technology Technology Requirements Requirements Prescriptive Performance Based Methods Prescribed Method Any Method Methods Existing LWR regulation Released NRC Part 53 draft text Goal for a flexible regulatory framework 6

Part 53 could enable selection of framework pathways that meet facility or project goals Innovative: Development of new regulatory paradigm Establishment of new regulatory precedent New Commission policy decisions Consistent, Uniform flexible, performance Approval of topical reports for new methods predictable requirements regulation Development of new regulatory guidance Evolutionary: Continuing development of existing regulatory paradigm 7

Part 53 framework can be reimagined to facilitate both evolutionary and innovation regulations Clear Regulatory Purpose Statement Application-specific Uniform Performance Requirements regulatory decisions Self-Consistent Project-Specific Performance Requirements Project Safety Case Basis General regulatory guidance and Optional Prescriptive Methods approvals Regulatory rule contents Supporting materials 8
