Boron-containing polyethylene board for radiation shielding materials for nuclear fusion and fission in nuclear power plants, and boron-containing polyethylene shielding door shielding room wall.
Boron-containing polyethylene board is a composite material made by evenly integrating boron into a high-density polyethylene substrate. Boron is known for its excellent neutron absorption ability, which can effectively absorb neutron radiation generated during nuclear reactions, thereby significantly reducing radioactive hazards. Polyethylene, as a substrate, gives the material good mechanical properties, processing properties and corrosion resistance, allowing boron-containing polyethylene boards to maintain stable performance in extreme environments .
Nuclear fusion and nuclear fission are the two main ways to utilize nuclear energy. Although they have huge energy, the accompanying radioactive ray problems cannot be ignored. During nuclear fission, heavy nuclei split into lighter nuclei, releasing a large amount of energy and neutrons; while nuclear fusion is the combination of light nuclei into heavy nuclei under high temperature and high pressure, which is also accompanied by strong radiation. If these rays are not effectively shielded, they will cause irreversible damage to personnel, the environment and even the ecosystem.
Different nuclear power plants or nuclear facilities have different requirements for radiation shielding materials due to differences in their operating conditions, reactor types and safety standards. Therefore, it is particularly important to support customization of the boron content of boron-containing polyethylene sheets. By precisely controlling the addition ratio of boron elements, it can be ensured that the material maintains optimal physical properties and cost-effectiveness while meeting specific shielding requirements. This flexibility not only expands the application range of the material, but also provides more possibilities for the safety design of nuclear power plants.
