Abstract

The study of the maximal load capacity of the moveable coil electromagnetic drive for reactor control rod has been conducted at Institute of Nuclear and New Energy,Tsinghua University.The experiment finds that the load value of the control rod drive mechanism（CRDM） is linearly increasing following the current value of the coil,and the maximal load is 2276 N when the current value is 5A.The maximal load of CRDM declines clearly at running condition,and the decline scope is about 12%.The CRDM carrying capability is linearly increasing as the coil current,and relates with the running speed of the coil.
