Abstract
An annular tank for storing nuclear reaction material in an annular space formed among seamless upper and lower annular dies disposed elevationally in a predetermined space and inner and outer sheaths extended on the inner and outer peripheral surfaces of the upper and lower dies. The tank avoids thermal strain and deformation by forming the upper and lower dies in a seamless manner to thus enhance the heat dissipating effect together with high working accuracy and strength. The method of fabricating the annular tank is simple by omitting the use of jigs for welding the segments with less loss and high production yield.
