Summary:The present invention provides an integrated passive reactor system comprising a pressure vessel, a containment vessel arranged outside the pressure vessel and a reactor core arranged inside the pressure vessel, wherein the primary loop operates in full natural circulation. The integrated reactor system is also provided with a secondary side passive residual heat removal system comprising primary loop heat exchanger(s) arranged inside the pressure vessel and passive residual heat removal heat exchanger(s) arranged outside the containment vessel, wherein the primary loop heat exchanger(s) is/are arranged above the reactor core, the passive residual heat removal heat exchanger(s) is/are arranged inside water tank(s) which is/are fixed outside the containment vessel, and the primary heat exchanger(s) and the passive residual heat removal heat exchanger(s) are connected by heat exchanger inlet pipelines and heat exchanger outlet pipelines. By adopting passive safety technology and passive residual heat removal system, and with the help of top double-layer structure of pressure vessel and break isolation measures, the integrated reactor system according to the present invention can reduce the loss of coolant to the greatest extent, thus meeting the requirements for mitigating design basis accidents, ensuring reactor safety and simplifying the design of the system.
