Abstract
A hexagonal ring structure whose internal contour conforms to the external contour of the reactor core rests on the periphery of the reactor diagrid and is constituted by a plurality of layers of metallic plates. The layers are maintained in relative positional relation by means of clamping members, the plates of one layer being angularly displaced with respect to the plates of adjacent layers. The bottom end-connectors of the elements constituting the lateral shield system are fitted in vertical through-holes formed in the ring structure.
