the fission of 235u (uranium - 235) nuclei is initiated by
Uranium-235 The fission of one atom of uranium-235 generates 202.5 MeV = 3.24 × 10−11 J, which translates to 19.54 TJ/mol, or 83.14 TJ/kg.[2] This is around 2.5 million times more than the energy released from burning coal.[3] When 235 92U nuclides are bombarded with neutrons, one of the many fission reactions that it can undergo is the following (shown visually in the adjacent image):
