摘要
核防护运输容器的主要辐射防护层是铸铅层。本文详细研讨了铸铅工艺，为了保证浇铸质量，针对不同组件进行不同工艺设计：外壳防护层采用底注式一次铸成、顺序凝固等方法，而底盘铅层则先访后压，再机加工到尺寸。浇铸系统确保了工艺设计的实现。最后浇铸成的两组件，经放射性检测，完全符合性能要求．
The main rediation shielding of transporting container for the reactor coolant pump hydraulic assembly is lead casting Layer. This paper researches in detail the lead casting process. In order to assure casting quality, the different technical design for different parts isadopted. The shielding case is completed on its first cast by bottom casting,sequential solidifyetc. But the lead layer of chassis base is casted at first, then pressed, followed by machiningto the right size. Casting system assure the realization of technical desgin. Two parts castedlast prove that the performance is in accord with requirement through NDT.
