To me modular means being able to buy one or 10 of these off the production line, plug them in and turn them on. A fantastic way of converting coal or gas power plants as they age or otherwise become non-viable, because a big part of the necessary support infrastructure is already there. All it needs is the manufacturing production line to actually exist, and the fuel supply chain and waste management which is unfortunately mostly political and the biggest risk to this sort of project.
