The invention provides a thermal container type integrated reactor, which comprises a pressure shell cylinder body; the lower part in the pressure shell cylinder body is provided with a poison tank; the poison tank comprises an inner shell of the poison tank and an outer shell of the poison tank; an upper boron water cavity for holding the boron water is formed between the inner shell and the outer shell of the poison tank; a passive shutdown system is arranged on the poison tank at the upper part of the boron water cavity; a reactor core is arranged in the middle of the bottom part of the inner part of the poison tank, and the outer part of the poison tank is provided with a steam generator; the inner part of the pressure shell cylinder body is provided with a driving device; an upper cavity is arranged in the pressure shell cylinder body at the upper part of the steam generator, and connects the poison tank with the steam generator; an annular declining channel is formed between the poison tank and the pressure shell cylinder body, a circumferential side of the lower end of the reactor core is provided with a radial coolant flow path; the radial coolant flow path connects the declining channel with the reactor core. The creation cancels a control bar in a traditional pressurized water reactor; the reactor is the reactor type for mounting the poison tank in the pressure container.
