Description

Nuclear power engine device
Technical Field
The invention relates to the field of nuclear reactor engineering technology and power plant design, in particular to a nuclear power engine device.
Background
The peaceful utilization of nuclear energy can be realized by artificially controlling the speed of the chain fission reaction. A great deal of heat can be released in the fission reaction, the atomic energy generated in the fission process is converted into heat energy by the reactor, the heat energy is carried away by the coolant and is transmitted to the power device through the energy conversion device, and finally the heat energy is converted into mechanical energy to generate thrust to drive the aircraft to fly.
Conventional aircraft engines use jet fuel as the fuel, and aircraft are limited by fuel carrying capacity, typically only hundreds to thousands of kilometers. The nuclear power engine has extremely high energy density, a reactor with hundreds of megawatts of power only needs a space of a few cubic meters, and the demonstration shows that the parameters of the nuclear power engine, such as weight, volume and the like, can meet the bearing requirements of the aircraft, so that the nuclear power engine can be well adapted to the aircraft. And the nuclear fuel has long service life, and can maintain the output power for several months or even years through reasonable design, which endows the reactor with long-time and great energy output capability, so that the aircraft using the nuclear power engine can realize extremely long voyage.
At present, for nuclear power engine devices adapted to ground and ship gas turbines, aviation turbofan engines, turbojet engines, turboprop engines and turboshaft engines, two schemes of direct circulation and indirect circulation are available through experimental verification. The direct-circulation nuclear power engine has the characteristics of direct principle, simple circulation and convenience in installation. However, direct cycle engines inject radioactive material directly into the atmosphere, causing severe radioactive contamination in the flight zone. The indirect cycle engine separates the reactor system from the propulsion system, overcoming the problem of radioactive contamination, but in order to pressurize the primary coolant, the primary side generally requires a separate compressor. This design results in a reactor system that is relatively heavy overall and the arrangement of the nuclear power engine installation in the aircraft cabin cannot be made compact. In addition, the increase of the pipelines means that the leakage probability is increased and the possibility of the occurrence of a breach accident is increased, once the pipelines connected with the main pump are damaged, the operation of the nuclear power system is seriously influenced, even a serious accident of power loss is caused, and the serious accident can cause the great potential safety hazard of the whole power device.
