Problems solved by technology

However, the heat pipe also presents a new problem for the system design: in propulsion mode, the heat pipe must operate well below the maximum temperature of the fuel to avoid damage to the heat pipe due to overheating
This method increases the complexity and difficulty of development of the system, and reduces the reliability of the system during operation.

Abstract

The invention belongs to the technical field of nuclear reactors and discloses a heating pipe-type dual-mode space nuclear reactor core. The reactor core comprises a reactor core active zone, a reactor core cylinder, a radial reflection layer, an axial reflection layer and a control drum. The reactor core active zone is located in the reactor core cylinder. The axial reflection layer is located above the reactor core active zone. The axial reflection layer is a hollow cylindrical structure. The reactor core active zone, the axial reflection layer and a heating pipe are located in the cavity ofthe radial reflection layer. The reactor core can effectively prevent the heat pipe overheating and has the beneficial effects of safety and reliability such as passive and non-single point failure.

Description

technical field [0001] The invention belongs to the technical field of nuclear reactors, in particular to a heat pipe type dual-mode space nuclear reactor core. Background technique [0002] Dual-mode space nuclear reactors have the functions of propulsion and power generation at the same time, combining many advantages of nuclear thermal propulsion reactors and space reactor power sources over conventional energy sources. The reactor is very suitable for manned moon landing, manned Mars, space transportation and other missions. The United States, Russia and other space powers have carried out extensive research on dual-mode reactors, and proposed many reactor schemes, which can be mainly classified into three types. The following briefly introduces these schemes. [0003] Mohamed S.El Genk of the United States proposed a dual-mode reactor scheme based on a thermionic reactor in the document "ATopaz-II Bimodal Design Assessment Study and System Analysis". In this solution,...
