吊篮下挂分体式堆内构件设计研究

通过对模块式多用途小型压水堆（ACP100）结构特点进行分析，提出了一种吊篮下挂的分体式堆内构件，其吊篮组件悬挂于反应堆压力容器中部并由压紧筒组件压紧，该结构具有易于制造安装、冷却剂分流密封效果好、流量分配合理等优点。力学分析、控制棒驱动线综合实验、堆内构件流致振动实验结果表明，该结构具有很好安全性和可靠性，满足ACP100的功能需求。 

Design and Research of a Novel RVI with Separated Barrel Hang in Middle of RPV for ACP100

A novel reactor vessel internals (RVI), which a barrel assembly is fixed by the compression barrel assembly, and hang in the middle of reactor pressure vessel (RPV), was proposed by analyzing the structure characteristics of China small modular reactor (ACP100). This structure has many advantages, such as easy for manufacture and installation, good sealing performance, and well flow distribution capability. The results of mechanical analysis and control rods drive line comprehensive experiment and flow-induced vibration test show that it is with high security and reliability, and fully meets the functional requirements of ACP100.
