An integrated PWR nuclear reactor that requires no refueling and is cooled by natural convection. It is housed within a reactor containment unit which is transportable to a placement site and placed within an underground building that allows heat transfer from the reactor to the surrounding soil. Tire reactor containment unit encloses an integrated PWR nuclear reactor, a pressure and chemical control system, a safety system and a turbo generator. After its operational life, the reactor's water and air are replaced with inert gases, circulating by natural convection to remove decay heat to the surrounding soil. This enables the integrated PWR reactor, initially designed to generate electricity, to act as a dry storage facility for uranium fuel elements after the end of its operational life.

This invention discloses an intermittent twin satellite power generation system based on temperature difference initiation and its control method. The system includes a first and second phase change chamber with identical structures, a turbine generator set, a shading switching component, a heat dissipation and radiation component, a power regulation and energy storage unit, and a control unit. The two phase change chambers are connected to the turbine generator set through a gas power-generating circuit with a switching valve and a condensation return circuit with a check valve. The shading switching component can selectively expose one chamber to sunlight while shading the other. The heat dissipation and radiation component dissipates heat from the shaded chamber. The control method uses pressure difference to drive the working fluid vapor to generate electricity, with the exhaust gas condensing in the low-pressure cold chamber. When the pressure difference is exhausted, the shading plate switches the roles of the two chambers, entering a reverse power-generating cycle. The intermittent power generation pulses are smoothed by the energy storage unit and then continuously output. Utilizing the inherent temperature difference in space as its driving force, it does not rely on solar irradiance intensity, providing a novel high-power-density, long-life energy solution for deep space exploration and highly maneuverable satellites.
