Embodiment Construction
[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0029] It should be noted that when a component is referred to as being “fixed on” or “disposed on” another component, it may be directly on the other component or indirectly on the other component. When an element is referred to as being "connected to" another element, it can be directly or indirectly connected to the other element. The orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", etc. are based on the orientation or positional relationship shown in the drawings, and are for convenience o...

The invention provides an intrinsic safety integrated small nuclear power supply for a marine environment. The intrinsic safety integrated small nuclear power supply comprises a containment vessel, apressure vessel, a reactor core, a steam generator, a steam turbine generator unit, a condenser and a deaerator. According to the invention, conversion of nuclear energy, heat energy, mechanical energy and electric energy is achieved through the reactor core, the steam generator, the steam collecting and conveying pipe and the steam turbine generator unit; deoxygenated condensate water is formed through the condenser and the deaerator and is supplied to the steam generator for recycling through the water supply distribution pipe, so that equipment and the structure are simple, and the arrangement difficulty and cost of the equipment and the structure are reduced; the pressure resistance and safety of a nuclear power source are improved through the double-ball type containment inner shell;and due to the design of the ballast water tank and the ballast tank, the nuclear power source has the capacity of submerging and floating in the ocean, and the marine environment adaptability of thenuclear power source can be improved.
Description
technical field [0001] The application belongs to the technical field of nuclear power, and more specifically relates to an inherently safe integrated small nuclear power source for marine environments. Background technique [0002] Nuclear power is a means of generating electricity using self-sustaining chain fission reactions of fissile nuclides. At present, nuclear power is widely used in land-based nuclear reactor installations to provide power supply for land-based power grids. The long-term efficient and safe power supply of undeveloped islands, offshore drilling platforms, seabed exploration and deep sea exploration workstations in vast sea areas has a strong demand for small nuclear power sources in the marine environment. Most of the existing marine nuclear power system designs use or learn from the original marine nuclear power technology. The system composition is relatively complex, construction and maintenance are difficult, and there are large uncertainties in...
