摘要
5 MW供热堆使用水力步进式驱动系统作为控制棒驱动系统.它是一种不同于压水堆使用的电磁-机械式传动的一种全新的控制棒传动。它以反应堆冷却剂(水)为工作介质,经泵加压后,注入安装在压力壳内的水力步进缸。通过由电磁阀组成的控制单元,控制注入步进缸的流量,使缸外套作步进运动,拖动中子吸收元件;控制核反应的进行。整个系统包括有13套传动缸及其控制单元,所有的控制单元集成到两个组合阀体上。
The hydraulic step driving system is used for driving of control rods on the 5 MW DHR. The system is based on a new concept of control rod driving, which is different from electric-magnetic-mechanic driving used for PWR. The reactor coolant (water) is used as actuating medium, pressed by pump, and then injected into hydraulic step cylinders which are set in the reactor vessel. The outer tube of the cylinder will be moving step by step by controlling flow, driving the neutron absorber and controlling nuclear reaction. 5 MW DHR is the first reactor in the world, in which the hydraulic driving system was used. Using the system is for getting better safety, reliability and economy. The principle of hydraulic step driving, the design and experimental research of ,the system are described in the paper.
