Nuclear energy power generation system using liquid metal magnetofluid as working medium

Abstract

The invention discloses a nuclear energy power generation system using a liquid metal magnetofluid as a working medium, belonging to the technical field of nuclear energy and magnetofluid power generation. The nuclear energy power generation system mainly uses a magnetofluid nuclear reactor coolant as the working medium of a magnetofluid power generator simultaneously to take away the heat generated by a reactor core; and according to the nuclear energy power generation system, power generation is realized based on a direct cycle manner, so that a steam turbine-power generation part of a nuclear power station is saved, therefore the power generation efficiency of the nuclear power station is effectively improved. Moreover, no mechanical motion components are arranged in the power generation channel of the magnetofluid power generator, so that the design becomes easier, the cost of the system is reduced, and the stability is increased; the dependence and waste of water resource are avoided; and a liquid metal fluid is used as a coolant, so that environmental pollutions, such as CO2 emission, are prevented.

Description

technical field [0001] The invention belongs to the technical field of nuclear energy and magnetic fluid power generation, and in particular relates to a nuclear power generation system using liquid metal magnetic fluid as a working medium. Background technique [0002] The magnetic fluid generator is a new type of power generation method that began to be studied in the late 1950s. The principle of the magnetic fluid generator is the same as that of the ordinary generator. It is the law of electromagnetic induction. The moving conductor cuts the magnetic force line to generate induced electromotive force and induced current. [0003] There are two main types of magnetohydrogen generators, high-temperature plasma gas magnetohydrogen generators and liquid metal magnetohydrogen generators (Liquid metal MHD referred to as LMMHD). The former uses petroleum, coal, natural gas, etc. as heat sources and high-temperature ionized conductive gases as working fluids to generate power, ...

AI Technical Summary

Problems solved by technology

[0010] It can be observed from the above that the research on liquid metal magnetic fluid power generation has been carried out internationally for decades, but the progress is relatively slow, and there is still little research in this field in China

Moreover, there has not yet been a joint study of nuclear power plant reactor coolant and liquid metal magnetic fluid power generation, so this new power generation system provides a new direction for the in-depth research of the above two, which can be expanded into a new field. draw wider attention
