NEW MODE OF PILING THE SOLID MODERATOR BLOCKS IN A NUCLEAR REACTOR
Patent
·
OSTI ID:4096235
In order to gusrantee the aligmnent of the channels crossing the core of a nuclear reactor constituted by a pile of graphite blocks (this pile is built up in such a way as to allow the anisotropic expansion of the blocks), the blocks are arranged in a regular square lattice and are stacked one above the other in such a way that their central holes form the channels. They are connected by independent keys, having an oval parallelly faced lozenge shape, each key fitting in the corresponding slots of two succeeding blocks of the same column and in the slots of the corresponding blocks of an adjacent column. Succeeding keys having the same orientation and forming a row in a direction perpendicular to their faces are held at a distance by prismatic spacers lying in grooves provided at the horizontal edges of the blocks.
