Heat pipe reactor passive residual heat removal system based on heat radiation

The invention relates to the technical field of nuclear reactor residual heat removal, in particular to a heat pipe reactor passive residual heat removal system based on heat radiation, which comprises a hot trap, a reactor core and a heat pipe heat exchanger are arranged in the hot trap, a plurality of residual heat removal heat pipes are inserted into the reactor core, and the outer ends of the residual heat removal heat pipes penetrate through the heat pipe heat exchanger and then are exposed in the hot trap. Under the operation condition, the evaporation section of the residual heat removal heat pipe takes away heat from the reactor core, and the exposed section radiates heat to the periphery; under the reactor shutdown working condition, decay waste heat of the reactor core is continuously radiated outwards from the exposed section of the waste heat removal heat pipe, and under the reactor shutdown isolated network state, the radiation heat dissipation operation can still be continuously carried out.
