A method and device for removing decay heat from a liquid metal reactor using a thermosyphon so as to cool the reactor is disclosed. The method and device of this invention uses a thermosyphon heating part in place of a conventional air separator, thus improving its decay heat removal capacity. In the method of this invention, decay heat from the reactor is absorbed at the flowing air and additionally at the evaporator section of the thermosyphon. The absorbed heat at the evaporator section is, thereafter, dissipated to the atmosphere from the condenser section of the thermosyphon. In the liquid metal reactor installed at a position between a containment and a reactor support concrete wall, the thermosyphon is installed at a position between the concrete wall and the containment vessel. The thermosyphon has a vertical evaporator section, an inclined adiabatic section extending upward from the top end of the evaporator section, and a vertical condenser section extending upward from the top end of the adiabatic section. Using a thermosyphon also reduces the temperature of the exhaust air of the cooling channel.
