Experimental Study on the Scram of Electromagnetic Movable Coil Control Rod Drive Mechanism

Institute of Nuclear and New Energy Technology, Tsinghua Univ., Beijing, 100084, China

摘要: 可移动线圈电磁驱动机构是一种新型的反应堆控制棒驱动机构。对该型控制棒驱动机构本文进行了快速落棒实验,得到了各种工况的落棒时间和特性。还分析了造成落棒特性差异的原因,总结出了快速落棒的规律。结果表明:控制棒可移动线圈电磁驱动机构样机断交流时的落棒时间比断直流的时间长;控制棒落棒时间随着配重的增加而缩短;断电后电磁线圈中的剩余电流对落棒时间有较大的影响,断交流比断直流时的落棒时间增加300～700ms

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.
