Nuclear fission can occur spontaneously in some cases or can be induced by the bombardment on the nucleus with a variety. with m is mass (kilograms), c is speed of light (meters/sec. To calculate the energy released during mass destruction in both nuclear fission and fusion, we use Einstein’s equation that equates energy and mass: (7.5.1) E m c 2. Fission is much easier to achieve than fusion although fission produces long-term radioactive by-products that are. The mass of an elements nucleus as a whole is less than the total mass of its individual protons and neutrons. ![]() Fission is where a large, unstable nucleus is split in two and fusion is where two smaller nuclei are joined to create a larger nucleus. During this process, the unstable radioactive nucleus is split into two smaller nuclei. Fusion and fission are both nuclear processes that can be used to produce energy. ![]() When fissionable material is in small pieces, the proportion of neutrons that escape through the relatively large surface area is great, and a chain reaction does not take place. Nuclear fission is the process of splitting a heavy nucleus, such as uranium or plutonium, in two smaller nuclei of nearly the same mass. (Radioactive tritium is neither a fissile nor a fissionable material.) There are no enriched materials in a fusion reactor like ITER that could be exploited to. ![]() This process is known as fission (see diagram below). \), a source of neutrons, and an explosive device for compressing it quickly into a small volume. When a U-235 nucleus absorbs an extra neutron, it quickly breaks into two parts.
