BWXT Advanced Technologies Perspectives on Proposed 10 CFR Part 53 Steve Schilthelm, Director of Regulatory & Mission Assurance, BWXT Advanced Technologies May 16, 2023 1

Long Nuclear Heritage and NRC Licensed Activities DECADES WORLD CLASS VERTICALLY INTEGRATED of nuclear operation nuclear manufacturing nuclear laboratory to NRC experience facilities Category 1 fuel and reactor manufacturing facilities Lynchburg, Virginia Erwin, Tennessee 2

Nuclear Enabling Sustainable Power In-Space and On-Earth In-space power Space propulsion Technology Programs DOE: ARDP BANR Terrestrial Power DOD: Project Pele DOE/NASA: Space Nuclear Propulsion Program, Nuclear Space Propulsion Thermal Propulsion Development DOE/NASA: Fission Surface Power as Partner to Space Power Lockheed Martin Terrestrial microreactor concept Spacecraft image credit: NASA 3

BWXT Microreactor Developed Perspectives - General o Significant commitment demonstrated by NRC Staff and stakeholders o BWXT generally supports comments provided by NEI and USNIC o Rule is overly complex and will have both intended and unintended impacts that are very difficult to predict o Two frameworks unnecessary - single framework can accomplish if focused on requirements versus methodology o Rule offers opportunities for microreactors that align with BWXT interests 4

BWXT Microreactor Developer Perspectives - Specific Interests o Manufacturing License fits BWXT experience with factory manufactured reactors and business models being developed o BWXT Supports Alternate Evaluation of Risk Insights (AERI)

Currently assessing AERI entry criteria against our ongoing microreactor safety analysis work AERI does not need its own Framework B Bounding consequence thresholds can provide regulatory options in other areas such as security and operator licensing o Part 53 enables coupling of AERI and Manufacturing License Potential fit for certain designs and business models 5

Thank You!
