Kilowatt-level underwater nuclear reactor power supply

Abstract

The invention relates to a kilowatt-level underwater nuclear reactor power supply, comprising a fuel, a control drum, a radial reflection layer, a safety rod passage, a heat pipe and an axial reflection layer; the fuel is a columnar uranium-molybdenum alloy fuel, wherein the safety rod a passage and a heat pipe passage are arranged; the heat pipe is inserted into the heat pipe passage around the safety rod passage; the radial reflection layer is arranged on the outer side of the fuel, and the axial reflection layer is arranged at two ends of the fuel; the control drum is uniformly arranged inthe radial reflection layer. The kilowatt-level underwater nuclear reactor power supply has the beneficial effects as follows: the use of the uranium-molybdenum alloy fuel can avoid the risk of nuclear proliferation by using the fuel with a low degree of enrichment; the scheme uses the heat pipe to guide out core heat, eliminating two larger pressurized water circuits of TRIOS, and the heat pipe has the advantages of being passive and achieving non-single point failure.

Description

technical field [0001] The invention relates to the field of nuclear power engineering, in particular to a kilowatt-level underwater nuclear reactor power supply. Background technique [0002] According to public information, so far, there is no underwater kilowatt-level reactor power supply that has been practically applied in the world. In terms of related reactor power supply design schemes, there are TRIOS underwater reactor power supply schemes in the United States and Kilopower space reactor power supply schemes in the United States that are relatively close to this scheme. [0003] In the literature "Undersea Thermionic Reactors", D.T.Allen et al. of the United States proposed a submarine fixed reactor power supply called TRIOS. The reactor uses two kinds of fuel rods, which are 9 thermionic fuel elements and 106 uranium hydrogen zirconium fuel elements. Fuel, which provides sufficient reactivity for the core, while the inherent negative temperature coefficient of t...
