SDA
NRC Standard Design Approval
NRC Standard Design Approval (SDA) certifies reactor designs without site-specific elements under 10 CFR Part 52, Subpart B.
SDAs reference certified designs for COL applications, as used for System 80+ and ABWR. Limited to standard configurations without probabilistic risk assessment exemptions. Valid 15 years.
Why it matters now
SDAs facilitate 2025-2026 SMR referencing in COLs, speeding data center project timelines post-HALEU qualification.
