AP1000余热排出换热器支承框架W形钢和方形钢的制造

摘要

为了确保我国核电厂的安全运行，在A P1000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.
