A nuclear reactor is a device that can manage a self-sustaining series of nuclear-fission reactions. Neutrons freed in one reaction may hit other heavy nuclei, causing them to split. Fission is the process in which a nucleus splits into two smaller pieces. A large amount of energy is released in this process.
In a nuclear reactor the chain reaction is maintained at a steady pace. The rate of this chain reaction is controlled by materials, usually in the form of rods that take in neutrons. Nuclear reactors are designed so they can't blow up like atomic bombs. Control rods made of boron are…
