Answer:
By absorbing neutrons, the control rod prevents further neutron fission. Control rods are an important safety system for nuclear reactors. Their rapid action and prompt reaction to the reactor are irreplaceable. Control rods are used to maintain the desired state of fission reactions in a nuclear reactor (i.e. subcritical state, critical state, power changes). They form a key component of the Emergency shutdown system (SCRAM).

Control rod assembly for the VVER reactor. Absorber – boron carbide
Control rods are typically cluster assemblies of control rods (PWRs) inserted into guide sleeves inside a nuclear fuel assembly. The shell protects the absorbing material (e.g. boron carbide granules), usually made of stainless steel. They are grouped into groups (rows), and movements
