Description

In an electromagnetic pump of the present invention for use in circulation of coolants in an LMFBR type reactor, the outer circumference of coil conductors is covered by an insulator retaining cover, and powdery or granular insulator is filled between the coil conductors and the insulator retaining cover. Upon reaching high temperature, elongation of the coil conductors by heat expansion is absorbed by movement of the particles of the powdery insulator thereby preventing excess stresses from exerting on the coil insulator constituted with the insulator retaining cover and the powdery or granular insulator and preventing generation of crackings on the coil insulator. Thus, plant stability is improved. (N.H.)
