The patent application (Publication Number: US20240029904A1) describes an integrated passive reactor system with various components such as a reactor main loop, containment cooling system, residual heat removal system, and core cooling system. The reactor main loop includes a pressure vessel with a core, pressure regulator, diversion device, and steam generator. The containment cooling system helps in reducing temperature and pressure within the containment, while the residual heat removal system cools the fluid in the steam generator when necessary. The core cooling system includes a pressure relief pipeline, safety-injection tank, and auxiliary circulation device to maintain proper cooling of the core under different conditions.

Furthermore, the integrated passive reactor system also features main pumps for driving the reactor coolant fluid, a containment cooling system with a heat exchanger and cooling water tank, a residual heat removal system with a heat exchanging device, and a core cooling system with additional components like a gravity injection pipeline and pit recirculation pipeline. The patent also details the configuration of the steam generator, auxiliary circulation device, and safety valves within the system to ensure efficient and safe operation. Overall, the patent application outlines a comprehensive design for an integrated passive reactor system with multiple safety features and cooling mechanisms to enhance the overall performance and reliability of the reactor.
