摘　　要：随着人类对能源的需求不断增长,国际核工程界提出发展第四代核电系统的主张,铅铋快堆是第四代反应堆系统6种堆型之一。铅铋快堆的停堆机构采用齿轮齿条式控制棒驱动机构,该机构主要功能为抓取和释放控制棒、升降与悬停控制棒及快速落棒。该文经过分析与初步试验,所设计的铅铋快堆控制棒驱动机构符合设计指标要求,并通过设计防反弹装置,达到了防止倾翻事故工况要求。With the increasing demand for energy,the international nuclear engineering community proposes to develop the fourth generation nuclear power system.Lead bismuth fast reactor is one of the six types of the fourth generation reactor system.Rack and gear control rod drive mechanism is used in the shutdown mechanism of lead bismuth fast reactor.The main functions of the shutdown mechanism are grabbing and releasing control rod,lifting,descending and holding control rod,dropping rod quickly.After analysis and preliminary tests,the designed lead-bismuth fast reactor control rod drive mechanism meets the design index requirements,and through the design of an anti-rebound device,the requirements for preventing tipping accidents are achieved.
