Abstract
Control rod is a key safety control system for nuclear reactors, with the scram time parameters being crucial to reactor safety. Therefore, scram tests of the electromagnetic movable coil control rod drive mechanism were conducted for various flow velocities. The software VC is used to control the experiment and record the data. The scram time is obtained by analyzing the data. Analysis of the variations of the scram time shows that in each case, the scram time is less than 1 s and that the electromagnetic movable coil control rod drive mechanism functions in accord with the reactor design.
