Burnable Poison

Name:
Burnable Poison
Detailed information:
A neutron absorber (poison) such as boron that when incorporated in the fuel or fuel cladding of a nuclear reactor, gradually “burns up” (is changed into nonabsorbing material) under neutron irradiation. This process compensates for the loss of reactivity that occurs as fuel is consumed and fission-product poisons accumulate and keeps the overall characteristics of the reactor nearly constant during use.
