Fission byproducts
WebA small number of fission products also have very long half-lives, notably technetium-99 (212,000 years) and iodine-129 (16 million years.) Some repository risk studies suggest … WebFission is the opposite of fusion and releases energy only when heavy nuclei are split. As noted in Fusion, energy is released if the products of a nuclear reaction have a greater binding energy per nucleon (BE/ A) than the parent nuclei. Figure 2 shows that BE/ A is greater for medium-mass nuclei than heavy nuclei, implying that when a heavy ...

WebDec 27, 2024 · Nuclear fission is a process when one atom of a fuel used in nuclear power plants splits in tiny particles. For example, a commonly used nuclear fuel is uranium, which splits in two fission byproducts. The atomic nuclei of these two byproducts are highly unstable. This means that they keep losing their energy in the form of radiation (that is ... WebNuclear fission is a process where the atomic nucleus splits apart; nuclear fusion is where atomic nuclei combine (or fuse) together. Both processes are .
