Shutdown control rod and reactor shutdown and cooling integrated system with same

The invention relates to a shutdown control rod and a reactor shutdown and cooling integrated system with the same. The outer surface of the shutdown control rod is coated with a neutron absorption coating; a closed cavity is formed in the shutdown control rod, and a liquid metal coolant is arranged in the closed cavity; when the shutdown control rod is inserted into a reactor core of a reactor pressure vessel, the neutron absorption coating can absorb neutrons to stop the chain fission reaction of the reactor core, and the liquid metal coolant can absorb heat generated by the chain fission reaction of the reactor core to vaporize, so that the temperature of the reactor core is rapidly reduced, and a relatively dangerous condition caused by continuous temperature rise of the reactor core due to waste heat is effectively avoided. Due to the fact that the reactor shutdown control rod can achieve the cooling function of the reactor core while achieving the reactor shutdown function, waste heat in the reactor cor
