IMPROVEMENTS RELATING TO CORE STRUCTURES FOR NUCLEAR REACTORS
A nuclear reactor core structure comprises a plurality of adjacent columns, each column consisting of a series of graphite blocks placed one above the other. Each block is suitably provided with an axial boring in such a way that the borings of the blocks of the same column form a reactor channel. Each block has a cross section symmetric with respect to the block axis. The distances between the axis of a given block and the axis of the blocks of adjacent columns are determined by a system of keys engaging in keyways in the lateral faces of the blocks. These keyways have sidefaces parallel to planes including the axis of the block in question, so that the keys connecting adjacent blocks are oriented according to at least three different planes of these planes. Suitably two of these planes form a right angle, while the third forms a bisection of the right angle. (IIB)
