Mission, G; Meulien, H

The assembly of solid moderator elements described is suitable for use on movable vehicles capable of subjecting it to substantial inclinations to the vertical and to considerable accelerations or decelerations. Each of the parallel moderator columns consists of a stack of blocks and includes an axial channel for receiving fuel elements and for permitting citculation of a refrigerant fluid. The columns are mutually independent and are capable of expanding laterally by reason of clearances provided between adjacent columns and axially by means of resilient guide means, which also provide axial compression for giving mechanical cohesion of each column. The resilient guide means comprise terminal members disposed at one end of each of the columns and carried by support members connected to the reactor casing and tubular terminal members disposed at the other end of each of the columns and surrounding fixed sleeves relative to which the tubular members are longitudinally movable, helical springs being seated between shoulders provided on each tubular member and its associated sleeve.
