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:

Analysis Advocacy Stakeholder Independent, Strong track Thought collaborationnon-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 ProbabilisticBeyond Design Criteria Analyses Basis Safety

Siting Design Basis Operational Requirements Analyses Safety Expert review Risk-informed, based regulation performance-based 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 OkloAurora 1120 MWe

• Operational requirements 1 MWe Water Cooled

• Equipment qualification Heat Pipe Cooled Evolutionary Regulation

• Reactor siting Innovative Regulation?

5 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-Uniform Performance Requirements specific regulatory Self-Consistent Project-Specific decisions Performance Requirements

Project Safety Case Basis General regulatory guidance and Optional Prescriptive Methods approvals
