Development of augmentation mechanism for large reactivity step in CFBR-II reactor

Linear motor, as the implementation mechanism for augmentation of large reactivity step in the CFBR-II reactor, is used to step increase the reactivity during the pulse burst. The whole system includes linear motor, Driving amplifier, Siemens PLC, ACE shock Absorber, and etc. The augmentation mechanism driven by linear motor can effectively overcome the disadvantages of pneumatic drive, and is featured by small volume, light weight, high speed movement, and high driving accuracy, and at the meantime, the linear motor can operate according to the preset rate curve.
