Decay chain of plutonium 239

WebOct 11, 2024 · An isotope of plutonium named plutonium-239 is fissile, which means that it can start a nuclear chain reaction. The United Nations lists it as one of only two radioactive isotopes used to... WebApr 10, 2024 · It has 92 protons and 146 neutrons in its nucleus. It is not fissile, which means it cannot sustain a nuclear chain reaction. However, it is fertile, which means it can absorb neutrons and undergo radioactive decay to produce other isotopes such as plutonium-239, which is fissile.

WebNuclear energy comes either from two nuclear reactions, fission and fusion. In the fission reaction, an atom with large atomic number such as thorium (232), uranium (235), or plutonium (239) is split into two or three lower atomic number elements when a neutron is absorbed. The fission releases large quantity of energy. WebPlutonium 240. 240 Pu is a fertile isotope because its fission cross-section is very low in comparison with fissile isotopes.Radiative capture of a neutron leads to the formation of fissile 241 Pu, similar to 238 U, which radiative capture leads to the formation of fissile 239 Pu.. It is a manufactured isotope and can be found in irradiated uranium fuel or spent …
