This is an infinitely tileable nuclear reactor design. It must be built on a lake using landfill, leaving two channels on either side of the reactor to provide water for the heat exchangers. The blueprint book contains 4 blueprints, reactor left side, reactor right side, heat exchangers, and turbines+steam tanks. One complete side of the reactor is 175 tiles wide, so a 2xN reactor would be 350 tiles wide total.
