Fast neutron reactor and alkali metal thermoelectric converter integrated device for exoplanet

Abstract

The invention discloses a fast neutron reactor and alkali metal thermoelectric converter integrated device for an exoplanet, which belongs to the technical field of nuclear power resources. According to the complete device disclosed by the invention, an alkali metal fast neutron reactor and an alkali metal thermoelectric converter are combined; the fast neutron reactor and alkali metal thermoelectric converter integrated device is formed by modularized equipment consisting of two barrels which are mutually inserted, has a simple structure, does not need to be connected by pipelines, depends on the natural circulation and does not require a pump or various valves and switches; the reliability of equipment is greatly improved; and various accidents can be avoided. A thermoswitch heat pipe is used as a waste heat discharge system and cannot be started under the normal working condition, so that the heat loss of a reactor core is avoided; and the heat pipe has excellent thermal conductivity, so that residual heat of the reactor core is timely conducted and the safety of the reactor core is ensured. The device can be placed on the moon or other exoplanets to provide daily domestic electricity or electricity for large-scale equipment and can also be used for providing continuous power for sparsely populated areas.

Description

technical field [0001] The invention belongs to the technical field of nuclear power energy, and in particular relates to an integrated device of a fast neutron reactor and an alkali metal thermoelectric converter for an alien planet. Background technique [0002] Developed countries led by the United States began to develop small modular reactors suitable for the space field as early as the 1960s, and made some progress. Most of the current experimental reactor types use early reactor types such as SP100 as templates, and fast neutron reactors use liquid sodium as the coolant. The heat generated by the fission is transferred to the thermionic power generation device at the other end of the heat pipe through the heat pipe inserted into the core. The thermionic power generation device generates thermions after heating, and then generates electricity. The system has complex structure, bulky size, low power, large number of pipelines, and inconvenient maintenance. And because...

Problems solved by technology

The system is complex in structure, bulky, low in power, large in number of pipelines, and inconvenient to maintain

And because there is no supporting device, the system is only suitable for outer space vehicles, not for installation on the surface of alien planets
