Simply put, fission is the division of one atom into two, and fusion is the combination of two lighter atoms into a larger one. They are opposing processes, and therefore very different. (Merriam-Webster Online, www.m-w.com). Nuclear fission releases heat energy by splitting atoms. The surprising discovery that it was possible to make a nucleus divide was based on Albert Einsteinâs prediction that mass could be changed into energy. In 1939, scientist began experiments, and one year later Enrico Fermi built the first nuclear reactor.
Nuclear power stations use the heat released by nuclear reactions to boil water to make steam. The type of nuclear reaction used is called nuclear fission. In nuclear fission: 1  A neutron collides with a uranium nucleus. 2  A uranium nucleus is large and unstable. 3  The uranium nucleus splits into two similar-sized smaller nuclei. 4  More neutrons are released. 5  These neutrons can then collide with more uranium nuclei.
