Generation III+
Generation III+ reactors are advanced LWRs with passive safety systems, longer life (60+ years), and standardized design for shorter construction.
Key designs: AP1000 (1100 MWe, NRC certified 2011), EPR (1600 MWe, FiR 2022), APR1400. Feature gravity-driven cooling, no AC power for 72+ hours, burnup to 60 GWd/t. AP1000 Vogtle units online 2023-2024 despite delays. GIF/NEA benchmark for safety/economics.
Why it matters now
III+ like AP1000 drives 2025 new-build economics for data centers. Licensing precedents aid SMR approvals.
