Provided is a flow distribution device, which comprises a flow distribution member (50) in a concave structure, wherein the concave structure forms a flow distribution cavity (53) having an opening, the flow distribution member (50) is arranged inside a pressure container (10) in a hung fashion and located right below a nuclear reactor core (30), the opening of the flow distribution member (50) faces towards the nuclear reactor core (30), a central hole (54) is further formed in the centre of the bottom of the flow distribution member (50) in a penetrating fashion, the central hole (54) is located right below the nuclear reactor core (30), and a plurality of flow splitting holes (55) are further formed in the flow distribution member (50) in a penetrating fashion; and under the actions of the central hole (54) and the flow splitting holes (55), a coolant can uniformly and stably flow into the nuclear reactor core (30), and the coolant is effectively prevented from generating a vortex under the action of the central hole (54) so that the uniformity and stability of the coolant flow distribution are further improved; moreover, since no vortex is generated, the safety and reliability of the nuclear reactor are guaranteed and the occurrence of nuclear safety accidents is reduced. Also disclosed is a nuclear reactor assembly with the flow distribution device. |
