The use of boron carbide in the nuclear industry
Boron carbide is used to make control rods, regulating rods, accident rods, safety rods, and extinction rods for nuclear reactors, to make boron carbide tiles, plates or neutron absorbers (made from high B10 content powder) for radiation protection, or mixed with cement It is used to produce the accelerating layer of nuclear reactors, which is a functional component formed by fuel nuclear components. Features: Boron carbide can absorb a large number of neutrons without any important isotopes, so it is an ideal neutron absorber in nuclear power plants and is also a core component of nuclear reactors. Neutron absorbers are mainly used to control the speed of nuclear reactors, but they are made into powder in order to increase the magnetic field. Boron carbide has a high neutron absorption equation, a wide absorption energy spectrum, low price, abundant sources of raw materials, and no strong secondary radiation of lambda rays after absorbing neutrons, so it is easy to handle. Therefore, boron carbide is an important neutron absorbing material. .
