Abstract: The movable magnetic coils control rod drive line, a new kind control rod drive line for reactors, regulates and controls reactor power by driving control rods with electromagnetic force. A series of verification tests were conducted to break through the key technology in development process. The theoretical basis of equipment development was verified by the principle test, making a breakthrough in the feasibility. The stroke test and life test not only verified the stability, reliability of the equipment, but also got its operation characteristic parameters. The anti-seismic test verified the security function in extreme conditions. The verification test data provide reference for the installation, regulation and safe operation of the drive line.
