Desired End State: Efficient, Effective, and Predictable Licensing Will we use Part 53?
- Must assume cost & schedule bases in the context of a project: insufficient data to do so today
- As an early adopter of RG 1.233 (LMP) and related approaches, X-energy is positioned to transition in the future when Part 53 can demonstrate improvement over Parts 50 or 52 Opportunities before us:
- Part 53 provides valuable insights into NRC staff thinking on advanced reactor policy matters today; near-term focus on advanced reactors in the current frameworks
- Getting Part 53 right is important, but not urgent to demonstrate these technologies in the 2020s
- Align on the right end state: establish the key metrics this rule must address DSA-influenced PRA-influenced LMP Framework for LBE Evaluation
