Development of Augmentation Mechanism for Large Reactivity Step in CFBR-II Reactor

Institute of Nuclear Physics and Chemistry, China Academy of Engineering Physics, Mianyang Sichuan, 621900, China

摘要: 使用直线电机作为CFBR-II堆大反应性阶跃添加的执行机构,用于在爆发脉冲的过程中阶跃地加入大反应性。整个系统包括直线电机、驱动放大器、PLC、油压缓冲吸收器等。直线电机驱动的大反应性阶跃添加机构,能较好地克服气动传动的缺点,具有体积小、重量轻、可高速运动、传动精度高等特点,同时直线电机可以按照预设速度曲线运行。
