> There are a bunch of Small Modular Reactor companies (Nuscale is probably the most well known in the media but venerable Westinghouse has one too). SMRs are mostly useful for small grids. Efficiency for large grids comes from large reactors (>700MW, and perhaps even 1000MW) that are built in a pipeline (I've heard the term "Large Modular Reactor"). When the province of Ontario built out its CANDUs it built them in pairs, and plants had 'packs' of fours and eights. It was a fairly standardized design and so the supply chain settled down and could churn out components.
