To avoid nuclear safety accidents as the Fukushima Daiichi Nuclear Power Plant and to ensure the operation safety, we introduced a passive residual heat removal device in AP1000 nuclear equipment The device requires an extra heat exchange and support frames made by W-shaped and square shaped steel which meet the requirement for nuclear safety class 1 equipment. At present, success is achieved in the manufacture process of W-shaped and square-shaped stainless steel. Through test and development, the shape, dimension, precision and other physical and chemical properties can meet the design requirement and can be used as nuclear safety class 1 supporting components. This product has been successfully applied in Sammen nuclear power project.
