You can also do large nuclear reactors in a factory if you use shipyard construction. In the 1970s Westinghouse and Newport News had a joint venture called Offshore Power Systems to do this. They employed 1000 people at their peak and did serious design and construction work of their nuclear plant manufacturing facility in Jacksonville Florida. In fact they actually got a manufacturing license to build eight gigawatt-class floating nuclear power plants in it from the NRC in 1982. https://www.sciencefriday.com/segments/floating-nuclear-power-plants/ https://www.sciencefriday.com/segments/floating-nuclear-powe... https://www.youtube.com/watch?v=0awiL0BeZ-k https://www.youtube.com/watch?v=0awiL0BeZ-k https://whatisnuclear.com/blog/2020-01-26-offshore-power-systems.html https://whatisnuclear.com/blog/2020-01-26-offshore-power-sys...
