Introduction to Reactor Core
A reactor core is the central part of a nuclear reactor where the nuclear fission reactions take place. It consists of fuel assemblies, control rods, coolant channels, and other components. The fuel assemblies contain the nuclear fuel, usually uranium or plutonium, which undergoes fission to release a large amount of energy in the form of heat. The control rods are used to regulate the rate of the fission reaction by absorbing neutrons. The coolant, such as water or liquid metal, is used to transfer the heat generated in the core to a steam generator or other heat - using devices.
The design and manufacturing of reactor cores are highly technical and safety - critical processes. High - quality materials, precise machining, and strict quality control are required to ensure the reliable and safe operation of nuclear reactors. In China, there are several leading factories that are at the forefront of reactor core manufacturing.
