高温气冷堆控制棒传动机构整体设置于一回路氦气环境,安装空间狭小,事故落棒时,缺乏有效的行程阻尼,因此,在球床模块式高温堆控制棒传动机构的设计中常采用结构紧凑的涡流限速器来吸收事故落棒的动能,减轻事故落棒对控制棒驱动线的冲击.本文简要介绍近年来涡流限速器在高温气冷堆中的实际应用情况,重点探讨了涡流限速器设计中的数值计算方法和实验方法.

As less damping caused by the helium gas atmosphere, the magnetic vortex damper is chosen to damp down the falling speed of the control-rod to reduce the shock applied to the drive mechanism located in the small space during the emergency shutdown. This paper introduces the practical applications of the magnetic vortex damper in the high-temperature gas-cooled reactor, focusing both the computational and experimental design methods in the recent study.
