Small modular reactors (SMRs) promise cheaper nuclear energy, supplying zero-carbon grid baseload and enabling new use cases for nuclear reactors. By shrinking the size of nuclear reactors compared to conventional large nuclear reactors, much of the construction is transferred to factory assembly lines, cutting capital costs and making nuclear power cost-competitive with renewables in many applications.
