Title:
ALKALI METAL REACTOR POWER SUPPLY
Document Type and Number:
WIPO Patent Application WO/2022/121878
Kind Code:
A1
Abstract:
An alkali metal reactor power supply, comprising: a reactor vessel (1), the bottom part of which is provided with a liquid alkali metal (2); a reactor core (4), which is arranged in the reactor vessel (1) and comprises a plurality of fuel rods (3) and a radial reflection layer (11) arranged at the periphery of the plurality of fuel rods (3), wherein the surface of each fuel rod (3) is provided with a first liquid absorption core (5), the bottom part of the reactor core (4) is provided with second liquid absorption cores (19) which are connected to the first liquid absorption cores (5), and the second liquid absorption cores (19) can be in contact with the liquid alkali metal (2); and alkali metal thermoelectric converters (7), which are arranged along the circumferential direction of the radial reflection layer (11), and divide the inside of the reactor vessel (1) into a high-pressure steam chamber (6) located above the alkali metal thermoelectric converters (7) and a low-pressure steam chamber (8) located below the alkali metal thermoelectric converters (7). By using the phase-change heat transfer of alkali metal, the circulating power of the liquid alkali metal (2) is provided by using the liquid absorption cores, the structure is simple, the arrangement is flexible, and the power generation efficiency is high.
