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 2

• 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 collaboration Independent, non-partisan Strong track record Thought leadership

NIA engages with other clean energy NGO stakeholders to inform comments and find common ground 3

& Leadership Engagement

Development of nuclear regulatory frameworks is an inherently iterative process 4

Expert review based regulation Siting Requirements General Design Criteria Probabilistic Analyses Design Basis Analyses Operational Safety Risk-informed, performance-based regulation Beyond Design Basis Safety
