一、前言随着核电站向大功率,高燃耗和长期运行安全性方向的发展,对堆芯结构材料的使用性能和使用状态提出了新的要求。锆合金包壳管材内表面喷砂处理工艺取代原酸洗处理工艺就是其中之一。锆合金包壳进往喷砂 I. Introduction With the development of nuclear power plants in the direction of high power, high fuel consumption and long-term operation safety, new requirements have been put forward on the performance and use status of core structural materials. Zirconium alloy cladding pipe sand blasting process to replace the original pickling process is one of them. Zirconium alloy shell into the sandblasting
