Each containment, vessel which produces 50MW of electric power, can fit on a truck. Each site might contain up to 12 separate reactors. That was basically the design constraint so the can be manufactured off site and shipped as one unit.

A regional power company might seek permitting at 10-20 locations. If some locations didn't get a permit or if other locations proved to be uneconomical to produce power at the time of construction, they could just build at the sites they chose. Basically takes the two phase pre-construction permitting and post-construction operating permit which has been killing nuclear power and streamlines it. Because the designs are standard and modular they will be pre-approved to operate.
