Problems of calculating and designing thin-walled cylindrical MHD-channels

The aper deals with problems of calculating and designing thin-walled channel designs for cylindrical linear induction pumps to be used for pumping liquid-metal coolants in NPP circuits. Designs in which thin walls are combined with rather high mechanical strength and stability are considered from the vieWpoint of mechanics. Dependences necessary for engineering calculatione of stress-strained states of channel elements are presentedj Thickness of shells may be decreased, as compared with traditional structures, in case of the channel shells rest on magnetic:conductors, or excessive pressure is built in the core, or the shells are connected by longitudinal ribs. The results obtained may be applied in developing large cylindrical MHD-pumps
