摘要
为了确保我国核电厂的安全运行,在AP1000核装置中设置了非能动余热排出装置,该装置需增加1台换热器及核一级使用的不锈钢W形钢和方形钢支承框架。目前W形钢和方形钢的制造工艺取得了成功。经试验、试制,其形状、尺寸、公差以及各项理化性能试验数据都达到了设计要求,可作为核一级支承件,现已成功应用于核电项目中。
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.
