THE BIG PICTURE: Small Modular Reactors
Interest in small modular reactors (SMRs) has ramped up of late owing to applications in niche electricity or energy markets where large reactors would not be viable—such as for cogeneration in countries with small grids, remote and off-grid areas, and for nuclear/renewable hybrid projects. Modular attributes may also enable SMRs to target the economics of […]
