Abstract

A nuclear reactor includes a reactor vessel containing an alkali metal thermoelectric converter. The bottom part of the vessel contains liquid alkali metal. A reactor core is arranged in the vessel and includes fuel rods. The surface of each fuel rod is provided with a first liquid absorption core. The bottom part of the reactor core is provided with second liquid absorption cores which are connected to the first liquid absorption cores. The cores are together configured to use capillary action to pump liquid alkali metal to an upper portion of an outer surface of the fuel rods, where the liquid alkali metal is vaporized into alkali metal vapor. The converter divides the inside of the reactor vessel into a high-pressure vapor chamber and a low-pressure vapor chamber. The converter is configured to receive alkali metal vapor from the high-pressure vapor chamber for use in electric power generation.
