AP1000机组MR40转运容器结构设计

Structure Design of MR40 Cask for AP1000 Unit

MR40转运容器专门用于抓取和转运AP1000机组水回路系统中产生的放射性废过滤器芯。本文结合抓取对象的结构形式和操作工况等要求,给出了1套设备的结构设计方案,采用1套带有提升机构的无动力自重式机械抓具的铅容器来满足废过滤器芯的抓取和辐射防护等要求,并进行了相关的辐射防护和力学计算。最终,设备制造完成后顺利完成了各项试验,证明该结构设计满足使用要求。

MR40 cask is specially used in gripping and transiting radioactive spent filter for water circuit system of AP1000 unit.In the consideration of the gripping object structures and the requirements of operators,a structure designation of one set of equipment was made,which is a lead vessel with a no-power dead-weight mechanical gripping tool with lifting mechanism to fulfill the requirements of gripping and radioactive protection etc.,and the relevant radioactive protection and mechanics calculation was done.Finally,all the tests have been passed after the completion of the equipment and the structure designation was proved to fulfill the functioning requirements.
