NEW MODE OF CONNECTION OF THE SOLID MODERATOR ARRANGED IN THE FORM OF A HEXAGONAL LATTICE IN A NUCLEAR REACTOR

OSTI ID:4095019
In order to guarantee the alignment of the channels crossing the core of a nuclear reactor constituted by a pile of hexagonal prismatic graphite blocks (these blocks being arranged in a regular hexagonal lattice), the blocks are stacked one above the other in such a way that their central holes form the said channels. Prismatic connecting elements having a star-shaped cross section with three radial branches, each having parallel side faces, are fitted in radial slots grooved into the blocks at their vertical edges so that each element connects three blocks of the same bed and the corresponding blocks of the succeeding bed. The elements of the same level are held at a distance by spacers lying in grooves provided at the horizontal edges of the blocks. Because of the anisotropic expansion of the blocks, the columns must be separated by free spaces. (NPO)
