WebU-235 is the only naturally occurring isotope which is thermally fissile, and it is present in natural uranium at a concentration of 0.7%. U-238 and Th-232 are the main naturally-occurring fertile isotopes. The probability that fission or any another neutron-induced reaction will occur is described by the neutron cross-section for that reaction. WebFission is the nuclear process that involves the splitting of a nucleus.

Some isotopes such as californium-252 can spontaneously fission, though most isotopes that are can undergo fission need ...

WebUranium. Uranium is a trace element that occurs naturally in the earth's crust. All of the isotopes of uranium are unstable and are radioactive. The most abundant isotopes are 238 U and 235 U. The percentage abundance of 238 U is 99.25 percent and the abundance of 235 U is 0.75 percent. WebThe vast majority of nuclear power reactors use the isotope uranium-235 as fuel; however, it only makes up 0.7% of the natural uranium mined and must therefore be increased through a process called enrichment. This increases the uranium-235 concentration from 0.7% to between 3% and 5%, which is the level used in most reactors.

WebEnergy from the uranium atom The nucleus of the U-235 atom comprises 92 protons and 143 neutrons (92 + 143 = 235). When the nucleus of a U-235 atom captures a moving neutron it splits in two (fissions) and releases …
