Integral Light-Water Small Reactors
Compact integral-vessel boiling- and pressurised-water reactor designs with passive safety allow licensable 300 MW-class units to be permitted and built on constrained sites and grids that cannot host gigawatt plants.
Developed mainly in: United StatesImpacting: North America and Europe
The U.S. Nuclear Regulatory Commission approved a construction permit for Clinch River Unit 1, a 300 MWe BWRX-300 small modular reactor from GE Vernova Hitachi Nuclear Energy, at the Tennessee Valley Authority's site near Oak Ridge, Tennessee. It is the first U.S. permit for this design and only the second advanced reactor construction permit issued. No start date was given.
