Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] Such as figure 1 As shown, the deep-sea nuclear power plant includes a reactor 1 , a thermoelectric conversion module 3 , a secondary loop 4 , a secondary loop driving pump 5 , a channel interlayer 6 , a pressure chamber 7 and an auxiliary system 8 .

[0027] The reactor 1 is a liquid metal reactor, which adopts liquid metal circulating flow for heat transfer. The reactor 1 envelops the core 2, and the core 2 and the thermoelectric conversion module 3 provide a boundary for coolant circulation. After the liquid metal is irradiated by nuclear radiation, the neutron activation is low, and the radiation to the thermoelectric conversion module 3 is small, so the thermoelectric conversion module is allowed to be arranged inside the reactor 1 . The reactor 1 is located at the lower part of the pressure chamber 7, lowering the center of gravi...

Abstract

The invention discloses a deep-sea nuclear power device which comprises a reactor, a thermoelectric conversion module, a secondary circuit, a secondary circuit driving pump, a runner sandwich, a pressure cavity and an auxiliary system, wherein the thermoelectric conversion module is a static thermoelectric conversion module for converting heat supplied by the reactor into electric energy; waste heat is discharged into a deep-sea environment through the secondary circuit and a pressure cavity. The deep-sea nuclear power device is provided with no moving component, so that continuous operation limitation of a conventional nuclear power device can be broken through; a static thermoelectric conversion system directly exchanges heat with the reactor, so that the overall efficiency of the systemis improved.

Description

technical field [0001] The invention relates to the technical field of nuclear energy engineering, in particular to a deep-sea nuclear power device. Background technique [0002] The ocean occupies 71% of the earth's surface and contains abundant natural resources. Due to the over-exploitation of offshore resources and environmental pollution, the utilization of marine resources is developing towards the far sea and deep sea. Conventional submersibles use batteries as energy sources and can only operate for short periods of time, severely limiting their operating range. The high energy density of the nuclear energy system can increase the endurance and speed of deep-sea underwater energy by an order of magnitude, and greatly promote the research work of deep-sea. [0003] Japan has done a lot of research in the field of deep-sea nuclear power. On the basis of marine reactors, it has developed deep-sea small reactor DRX, small submersible reactor SCR for underwater detector...
