우라늄-235 핵분열
235U + 1n → 141Ba + 92Kr + 31n
개요
A uranium-235 nucleus absorbs a slow neutron and splits into barium-141 and krypton-92, releasing three neutrons and approximately 200 MeV of energy. This is one of many possible fission product combinations. The three released neutrons can trigger further fissions, creating a chain reaction. One kg of U-235 releases energy equivalent to 20,000 tonnes of TNT.
