The Fission Process | MIT Nuclear Reactor Laboratory
WEBWhen a U-235 nucleus absorbs an extra neutron, it quickly breaks into two parts. This process is known as fission (see diagram below). Each time a U-235 nucleus splits, it releases two or three neutrons.

WEBFission properties. Nuclear fission seen with a uranium-235 nucleus. The fission of one atom of uranium-235 releases 202.5 MeV (3.24 × 10−11 J) inside the reactor. That corresponds to 19.54 TJ/ mol, or 83.14 TJ/kg. [5] . Another 8.8 MeV escapes the reactor as anti-neutrinos. When 235.
WEBUranium-235 is useful as a reactor fuel because: 1) It will readily absorb a neutron to become the highly unstable isotope U-236. 2) U-236 has a high probability of fission (about 80% of all U-236 atoms will fission).

WEBSep 5, 2024 — uranium-235 (U-235), radioactive isotope of the element uranium with a nucleus containing 92 protons and 143 neutrons. Uranium-235 is the only naturally occurring fissile material; that is, the uranium-235 nucleus undergoes nuclear fission when it collides with a slow neutron (a neutron with a kinetic energy less than 1 electron volt).
