Abstract

Abstract

Electromagnetic movable coil control rod drive mechanism is a new type drive mechanism.The drive mechanism is experimentally studied to gain the characteristic of scram time.Further more,the reason of the different scram phenomena is analyzed and the disciplinarian of scram is also summarized.On the base of series experiments it can be concluded that scram time of AC break is longer than that of DC break and the residual current of coil’s can distinctly influence the scram time.The scram time of AC break is 300~700 ms longer than that of DC break.
