Abstract
A nuclear island base slab of a nuclear power plant and a manufacturing method therefor, and a nuclear island of a nuclear power plant. The nuclear island base slab of a nuclear power plant includes a concrete base slab body and a plurality of air ducts embedded in the concrete base slab body. The air duct has an internal-penetrating bent pipe structure. A first end of the air duct is exposed on an upper surface of the concrete base slab body. A second end of the air duct is exposed on a side surface or the upper surface of the concrete base slab body.
