Steady Control Rod Drive Mechanism in Xi'an Pulsed Reactor

西安脉冲堆稳态控制棒驱动机构是实现反应堆启动、功率调节和停堆的关键设备。该机构采用滚珠丝杠副的传动方式,通过电磁铁的吸合,可以带动稳态控制棒上下运行,当释放电磁铁时,可以实现快速落棒。本文介绍了稳态控制棒驱动机构的结构特点、设计参数和试验情况。该机构已成功应用于西安脉冲堆。

Steady Control Rod Drive Mechanism (CRDM) in Xi'an Pulsed Reactor is one of the key equipments for implementing start-up, shutdown and power adjustment of reactor. It takes ball screws as drive machine, engaged electromagnet to drive steady control rod up and down, disengaged electromagnet to drop the control rod rapidly. The structure characteristics, the parameter of design and the test results of CRDM are presented. The machine has been used for Xi'an Pulse Reactor successfully.
