Westinghouse Non-Proprietary Class 3 eVinci Micro-reactor Deployment Test Reactor for Safety Feature Performance Assemble in Factory Transport to Site Install and Operate at Site Transport Away from Site Refuel/Refurbish Decommission or Test Reactor - Testing, Data Collection, and Analysis Primary Reactor Replacement Reactor Depleted Reactor Standard Design Certification per 10 CFR Part 52 Subpart B Remote Monitoring Station Limited Site Staff and Remote Operations Westinghouse eVinci licensing strategy relies on current Part 52 regulations eVinci Micro-reactor Deployment Model

10 CFR Part 53 Development

Westinghouse is supportive of a risk-informed regulation for advanced reactors

Treatment of safety functions, design criteria, and design features is beneficial

Potential efficiency gains in applications (e.g., fewer exemptions)

Key challenges

Draft rule adds onerous requirements for micro-reactors

Does not address regulatory requirements for micro-reactor deployment Westinghouse Non-Proprietary Class 3

Global climate change commitments and energy/national security concerns are driving the need for existing and new nuclear

AP1000 is ready now to address near-term energy needs

eVinci to support growing demand for distributed clean energy

Westinghouse supports NRC Part 50/52 rulemaking efforts

Eliminate Design Certification expiration

Consider broader risk-informed, performance-based regulations for LWRs

Streamline process to allow vendors to update Design Certification recognizing lessons learned from constructed certified designs Westinghouse Perspective on Priority Westinghouse Non-Proprietary Class 3
