摘要

Core device for nuclear reactor with solid moderator, device whose central part at least comprises vertical columns each constituted by solid bars of the same section, superimposed, of moderating material, columns maintained relative to each other by keying means, and channels parallel to the columns, limited by them and intended to receive fuel elements, these channels being arranged in the upper parts of a regular network whose passage is greater than the largest dimension of the straight section of any one of the columns, said device resting on a supporting surface and being surmounted by a ballast, characterized in that the ballast is divided into adjacent organs separated by gaps and arranged according to a network identical to that of the channels, because each of said organs is coupled to the adjacent organs by keying means arranged according to at least three planes passing through the axis of the organ, and by which means are provided for coupling between said organs and the columns to maintain the identity of the network of the channels and that of said organs.
