IMPROVEMENTS RELATING TO NUCLEAR REACTORS IN PARTICULAR TO HETEROGENEOUS GAS COOLED REACTORS
For a nuclear reactor with a horizontal charging floor situated above the reactor vessel, annular means are provided for shielding the radioactive fuel elements during the transfer from the charging hole into the charging machine as from the moment that the opening of the latter is brought into alignment with the said charging hole. The charging machine is movable on the rails of a bridge- like carriage, which is able to travel on rails situated on two sides of the charging area. Preferably said annular shielding means are also movable in two horizontal directions by an appropriate carriage system and comprise suitably a lower and an upper part pressed respectively against the charging floor and the lower surface of the charging-machine. The surfaces of these parts have opposing zigzag profiles, which interpenetrate so that there is nowhere a free path for radiation through the interspace bounded by these surfaces. (NPO)
