![]() The process may take place spontaneously in some cases or may be induced by the excitation of the nucleus with a variety of particles (e.g., neutrons, protons, deuterons, or alpha particles) or with electromagnetic radiation in the form of gamma rays. 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. In nuclear fission the nucleus of an atom breaks up into two lighter nuclei. A fusion reactor produces helium, which is an inert gas. With more than 400 commercial reactors worldwide, including 93 in the United States, nuclear power. Fusion on the other hand does not create any long-lived radioactive nuclear waste. That heat is used to make steam that spins a turbine to create electricity. ![]() They contain and control nuclear chain reactions that produce heat through a physical process called fission. nucleosynthesis with a farnsworth-hirsch-fusor - a homemade nuclear fusion reactor that, in this case, fuses deuterium (H-2) atoms.the result is an intense o. \), a source of neutrons, and an explosive device for compressing it quickly into a small volume. Nuclear reactors are the heart of a nuclear power plant.
