Small Modular Reactors: Tiny Nukes, Big Revolution in Clean Energy
NuScale’s 77 MWe SMR became the first design certified by the U.S. NRC in 2020, with a six-module plant planned in Idaho by 2029. China’s HTR-PM began commercial operation in December 2023, while Canada licensed a 300 MWe BWRX-300 at Darlington in April 2025. The UK selected Rolls-Royce SMR for at least three units in June 2025, targeting grid connection in the mid-2030s.
