Liquid circulation cooling method for nuclear power stations

Abstract

The invention relates to a liquid circulation cooling method for nuclear power stations. The nuclear power stations are cooled through limited liquid circulation during operation, so that building of the nuclear power stations in water-free and unmanned areas such as deep deserts and deep mountains has conditions for implementation. Due to the fact that the quantity of liquid is limited, liquid which does not generate incrustation scale and is free of corrosivity can be adopted, cooling performance is improved, and corrosion to cooled parts is avoided. The nuclear power stations are built in the water-free and unmanned areas such as the deep deserts and deep mountains, and the influence of nuclear pollution generated by accidents on the environment and human beings is quite limited. Particularly, enough nuclear power plants are built in the deep position of the Inner Mongolia desert to completely replace chemical energy to be used in the North China, the Northwest China Region and the Northeast China Region, carbon peak reaching and carbon neutralization are certainly and greatly promoted, and the atmospheric environment quality in the North China, the Northwest China Region and the Northeast China Region is greatly improved.

Description

technical field [0001] The invention relates to a liquid cooling method for a nuclear power plant, in particular to a liquid circulation cooling method for a nuclear power plant. Background technique [0002] Existing nuclear power plants are all built on relatively densely populated seasides, riversides, riversides, and lakesides, using natural water systems for transient cooling. On the one hand, the hardness and corrosiveness of seawater, river water, river water, and lake water are relatively high. Not only does scale have an adverse effect on long-term cooling performance, but seawater and other high corrosiveness will also corrode cooled components and shorten the service life; on the other hand, if an accident occurs in a nuclear power plant, It will directly lead to the pollution of sea water, river water, river water and lake water, and the consequences of accidents will be more serious. For example, the nuclear disaster at the Fukushima nuclear power plant in Japa...
