Description

technical field [0001] The invention relates to the fields of nuclear reactor engineering technology and power device design, and in particular relates to a nuclear power engine device. Background technique [0002] The peaceful use of nuclear energy can be realized by artificially controlling the speed of the chain fission reaction. The fission reaction will release a large amount of heat. The reactor converts the atomic energy during fission into heat energy. The coolant carries this part of the heat and transfers it to the power plant through the energy conversion device, and finally converts it into mechanical energy, which generates thrust to drive the aircraft to fly. [0003] Traditional aircraft engines use aviation kerosene as fuel, and the aircraft is limited by the amount of fuel carried, and the flight range is generally only hundreds to thousands of kilometers. The energy density of nuclear power engines is extremely high, and a reactor with a power of hundreds...
