To avoid bending moment stresses in a horizontally arranged cylindrical pressure vessel for a nuclear reactor, which stresses would be induced by the weight of the reactor core arranged within the vessel, the supports for vessel and the supports for the core structure are arranged in radial alignment. The pressure vessel is kept in place on its support structure and the core structure is kept in place within the pressure vessel by supporting means at their top surfaces, viz. by systems of keys and keyways. Preferably the keys and keyways keeping the pressure vessel in place are V-shaped and radial movements of the vessel relative to its support structure may take place. Fixing belts clasping round at least a part of the surface of the vessel are anchored in the supporting structure arranged within the radiation shielding, this shielding being mounted on the main support by keys and keyways.
