摘要

System for fixing the core in a nuclear reactor, comprising an upper set of fixing ring, a supporting surface in the lower fixing and a plurality of fixing elements arranged circumferentially adjacent to said core, each of said fixing elements comprising a group of at least two torsion bars disposed parallel and spaced around said core, upper and lower arms transmitters of the moment to create torsional forces in said bars arranged in the vicinity of the ends thereof, said upper arm resting against said upper assembly of the fixing ring so that it exerts a rotational direction on said bar, while the lower arm rests against said support surface of the fixing so that it exerts a torsional force in the opposite direction, a set of upper shoe next to the upper end of said group of torsion bars and penetrated by the s and a lower shoe assembly proximate the lower end of said group of torsion bars and penetrated thereto, said upper and lower shoe assemblies abutting against the periphery of the fuel elements of said core.
