Modular Construction

Mitsubishi utilizes an “Over the Top” modular construction method for the US-APWR. For this method, large sections, or modules, are constructed and then set into place rather than traditional item-by-item construction.  This significantly reduces construction item for the plant.

           

To facilitate this construction method, a super crane is used to lift the large, prefabricated blocks and position them within the construction site.
