WebGenerating Heat Fission Fission produces energy and nuclear power plants use the fission reactions of U-236 to generate heat that then is converted to electricity. In a nuclear power plant, there is a chain reaction. Uranium-235 reacts with a neutron to generate uranium-236. This splits into fission products and also produces additional neutrons.

Nuclear fission can occur without neutron bombardment as a type of radioactive decay. This type of fission (called spontaneous fission) is rare except in a few heavy isotopes. In engineered nuclear devices, essentially all nuclear fission occurs as a "nuclear reaction" — a bombardment-driven process that results from the collis… WebAug 9, 2000 · A picture of a reactor is shown in Fig. 14-2. The energy released in the fission process, which is primarily in the form of the kinetic energy of the fission fragments, heats the water. The water serves both as a neutron moderator (it slows down the fission neutrons to thermal energies), and as a heat transfer fluid.
