摘　　要：重水堆核电厂自运行以来,装卸料机B推杆多次出现位置失效现象,导致换料中断、换料计划调整、甚至在通道关闭时装卸料机料仓超压而引起重水泄漏等情况。文章针对B推杆位置失效原因展开分析,重点分析了波纹管、减速器、机械计数器和电位计等B推杆的主要部件,就上述部件失效原因提出改进措施,从而大大减少位置失效现象。Since pressurized heavy water reactor （PHWR） put into operation, fueling machine ram B hadexperienced failure for many times, which further cause fueling inter ruption, schedule change, even overpressure of fueling machine and D2O leaking when the channel s closed. These article analyses the root cause of ram B fai lure,with emphasis on main components of bellow, speed reducer ,mechanical counter,and potentiometer. Regarding the failure cause, improvement measures are put forward in this article, and thus position failure is reduced significantly.
