Nuclear Graphite Products

Because of its special physical and chemical properties, graphite has become an indispensable strategic resource for the nuclear industry and the national economy, and also a key mineral for future high-tech development.

 

Importance of Nuclear Graphite Products

The graphite resources distribution is relatively concentrated in the world, and production is highly concentrated, the future world economic development to a graphite aggregate demand will increase steadily, with the application in the field of high technology breakthrough, especially the development of new energy vehicles, traditional industries such as steel and casting and pencil basically stable demand for graphite, the high-tech application will be greatly increased.

 

The graphite rods in the nuclear reactor

The high density graphite rod in the nuclear reactor produced by the company is an indispensable material for nuclear reactors and is widely used in nuclear power plants and military industry, the company has a long history of special graphite production, is the national nuclear industry and aerospace industry special graphite test and production enterprises.


Why Graphite Rod Is Used In Nuclear Reactor

Graphite rods play a critical role in nuclear reactors, particularly as neutron reducers. These rods are employed to slow down the high-speed neutrons produced during nuclear fission. Slower neutrons have an increased likelihood of interacting with uranium-235 nuclei, effectively sustaining the nuclear chain reaction, which is vital for energy production in nuclear power plants.


Moreover, graphite rods are integral for ensuring safety within nuclear reactors. They serve as structures that help moderate the speed of neutrons, preventing uncontrollable reactions and maintaining a controlled nuclear fission process. This function is paramount to avoid overheating and potential meltdowns in nuclear facilities.


Graphite rods also have unique applications in specific reactor designs, such as the RBMK reactor, infamous for the Chernobyl disaster. In such reactors, the role of graphite rods is particularly notable in controlling the nuclear reactions and ensuring stability.


How Is Graphite Used In Nuclear Reactors

You may want to know what does graphite do in a nuclear reactor. Graphite has a good neutron moderating agent and is used in atomic reactors. The uranium-graphite reactor is a kind of atomic reactor that is widely used at present. The decelerating material in the atomic energy reactor used for power should have a high melting point, stability, and corrosion resistance, and graphite can fully meet the above requirements. The purity of graphite used as an atomic reactor is very high, and the impurity content should not exceed tens of PPM. In particular, the boron content should be less than 0.5 PPM. In the defense industry, graphite is also used to make nozzles for solid-fuel rockets, nose cones for missiles, spare parts for space travel equipment, heat insulation materials and radiation protection materials.
