A nuclear reactor includes a reactor container, a reactor core, a control drum assembly, a hot channel, a heat exchanger and a main pump. The reactor container contains a coolant; the reactor core is arranged at a lower middle part of the reactor container; the control drum assembly is arranged on an outer periphery of the reactor core, and includes control drums arranged at intervals along a peripheral direction of the reactor core; the hot channel is arranged in the reactor container and located above the reactor core. The hot channel has a bottom hermetically connected to the control drum assembly and a top hermetically connected to an inner top surface of the reactor container. The hot channel has a hot pool passage for the coolant to pass through. The heat exchanger is arranged in the reactor container and located on an outer periphery of the hot channel.

Lead-cooled fast reactor utilizing control drums

A passive containment heat removal system and a control method thereof are provided. The system includes an outer containment an inner containment disposed in the outer containment, an air duct formed between the inner containment and the outer containment having an air inlet and an air outlet; a spraying assembly disposed outside the inner containment and configured to passively spray cooling water to an outer wall of the inner containment to cool the inner containment; a built-in heat exchanger disposed in the inner containment; an air cooling channel having an air inlet of the air cooling channel and an air outlet of the air cooling channel; an external air cooler disposed in the air cooling channel with an inlet connected with an outlet of the built-in heat exchanger via a first communicating pipe and an outlet connected with an inlet of the built-in heat exchanger via a second communicating pipe.
