Method for manufacturing guide pipe component of pressurized water reactor fuel assembly

The invention particularly relates to a pressurized water reactor nuclear fuel assembly guide pipe component manufacturing method which comprises the following steps: step 1, connecting an inner sleeve (1) in a guide pipe (3) in an expanded manner to form the expanded guide pipe (3); step 2, pressing an end plug (2) into the expanded guide tube (3); and step 3, welding a circular seam between the end plug (2) and the expanded guide pipe (3) through a vacuum electron beam welding machine to form the pressurized water reactor nuclear fuel assembly guide pipe part (3). According to the pressurized water reactor nuclear fuel assembly guide pipe component manufacturing method, the manufactured pressurized water reactor nuclear fuel assembly guide pipe component meets the fuel assembly manufacturing requirement. 本发明具体涉及一种压水堆核燃料组件导向管部件制造方法，包括如下步骤：步骤1、将内套管(1)胀接在导向管(3)内，形成胀接后的导向管(3)；步骤2、将端塞(2)压入胀接后的导向管内(3)；步骤3、通过真空电子束焊机将端塞(2)与胀接后的导向管(3)之间的环缝焊接，形成压水堆核燃料组件导向管部件(3)。本发明的压水堆核燃料组件导向管部件制造方法，制备的压水堆核燃料组件导向管部件满足燃料组件制造要求。
