Application of Boron Carbide in Nuclear Industry

Application of Boron Carbide in Nuclear Industry
Boron carbide has high neutron absorption capacity, high neutron capture cross section and wide capture energy spectrum. Boron has low cost, no radioactive isotopes, low secondary ray energy, corrosion resistance and good thermal stability, so it is more and more popular in the nuclear industry. Its main applications include: (1) Mixing B104C powder with graphite powder to make boron-carbon bricks, which are used outside the reactor to prevent the leakage of radioactive substances; (2) Pressing B104C powder into products at high temperature to be used as reactor control rods to control the reactor Reaction speed; (3) Press the B104C powder into a product at high temperature to be the shielding material of the reactor to absorb radioactive substances; (4) Use the normal pressure sintering process to sinter the B104C powder into a block, which is used for the shielding material of the reactor.
