反应堆控制棒驱动机构是反应堆系统中的重要部件,目前国际上普遍采用了电机结构,这种结构对电机的耐辐射性、密封绝缘等性能的要求很高,因而这种系统一般都十分昂贵。1991年清华大学核研院发展了一种新型水力驱动控制系统。水力驱动系统是依靠水力脉冲方波来实现控制棒的步升与步降的,对于步升来说,一般要求脉冲方波宽度为3
Reactor control rod drive mechanism is an important part of the reactor system. At present, the motor structure is universally adopted in the world. Such a structure has high requirements on the radiation resistance and sealing insulation of the motor. Therefore, such a system is generally very expensive. In 1991, Tsinghua University Nuclear Research Institute developed a new hydraulic drive control system. Hydraulic drive system is to rely on the hydraulic pulse square wave to achieve the control of the step-up and step-down, for step-up, the general requirement pulse square wave width of 3
