Abstract
Electromagnetic pumps have been employed to transport the various kind of liquid metal with the high electrical conductivity including circulation of liquid sodium in a sodium fast reactor. Especially, DC electromagnetic pumps have advantage of the simple geometrical structure without any impeller and sealing part, and the continuous flow control over mechanical pumps. However, the relatively high input current is required compared with that of the induction type electromagnetic pumps. In this study, for the liquid sodium circulation in the sodium-carbon dioxide reaction experimental loop, carried out is the design analysis on the pump electromagnetic and geometrical variables including the length, area and number of coil turns considering fluid effects for the design of the rectangular and helical type pumps with the flowrate of 3 L/min.
