Neutron poison refers to substances that can absorb neutrons and thereby reduce the number of neutrons available to sustain a nuclear chain reaction. These materials are crucial in nuclear reactors for controlling the fission process. By absorbing neutrons, neutron poisons help to manage the reactor's reactivity and ensure safe operation. Common neutron poisons include: - **Boron**: Often used in the form of boron carbide or dissolved in water, it is effective due to its high neutron capture cross-section.
