How is chain reaction controlled in a nuclear power plant? Chain reaction is controlled through using neutron absorbing materials as reactor control rods (of high neutron absorbing material), boron, and/or cadmium.
Except for the reaction itself, the method by which nuclear plants create power is no different from coal or oil power plants. Due to the danger of radioactive waste, however, the infrastructure of nuclear plants is quite different from other types of power plants, incorporating concrete radiation shields enclosed by steel containment fields.
