WebThe chain reaction is controlled by Boron control rods. Boron is a non-fissile material. This means it will not undergo a fission reaction when bombarded with neutrons. WebNuclear fission is the process in which the nucleus of an atom is split, forming nuclei of lighter atoms and neutrons. The mass of these products is less than the original mass. According to Einstein's equation E = m c 2, the small amount of missing mass is converted into a large amount of energy. A chain reaction occurs when the neutrons ...
