Fissionable material, that is, material with the ability to fission, occurs in some isotopes of heavy elements. The most useful ones are uranium-235 (U-235) and plutonium-239 (Pu-239).

In brief, when fission occurs, an atom of nuclear fuel (and we're talking about the fission of nuclear fuel here) splits. This splitting yields what are called fission fragments, and the atom splits approximately in two. Note that there are several options as regards what the atom splits into. It can split into "A" and "B" or it can split into "C" and "D" or a few other resultants. But regardless, the fission fragments recoil after fission occurs, and most of the energy of this recoil, which is kinetic energy on the atomic scale, is expressed as heat (thermal energy).

The fuel in a reactor, whatever it is, is tightly sealed in a metal jacket ( How_is_energy_released_in_nuclear_fission). The atoms of the fuel are being held rigidly, and when fission occurs, the recoil of the fragments is "contained" in the fuel itself. This mechanical energy gives rise to the appearance of thermal (heat) energy. The lion's share of energy released by fission is carried off in the recoil of the fission fragments, which is kinetic (mechanical) energy. Said another way, the fission fragments can't "go anywhere" in the fuel matrix, and the kinetic energy they come away with after fission is captured in the fuel and appears as heat.

There are also free neutrons released, and they carry off kinetic energy like the fission fragments. These neutrons are slowed down in the moderator to increase the chances that they will be captured by other fuel atoms and cause other fission reactions. They will continue the chain and cause more fissions following neutron capture events. Electromagnetic radiation in the form of gamma rays is also produced in nuclear fission. It must be shielded against. In review, most of the energy of fission appears in the kinetic energy of the fission fragments, and that kinetic energy is converted into heat within the fuel element.

A nuclear reactor is a core made up of an assembly of fuel bundles, which are made of fuel elements, usually using enriched uranium as the nuclear fuel. In the pressurized water reactor, this assembly is inside a How_is_energy_released_in_nuclear_fission, as water is used as the primary coolant, and also the moderator. It can be ordinary water or heavy water. We also see some reactor designs that use graphite as a moderator. Also in the reactor are the control rods.

The primary coolant is the heat transfer medium. It carries heat out of the core and into the steam generator and back to the core in a closed loop. The reactor is made to reach criticality on start up when control rods are pulled. The chain reaction within the fuel will produce a steady power output as a result of nuclear fission, and this will release heat. The heat is used to produce steam in a steam generator, and the steam is feed to a conventional steam turbine/generating unit to generate electric power.

For those investigators attempting to trace the transformations of energy, nuclear energy (the binding energy that holds atomic nuclei together) is converted into electromagnetic and kinetic energy in fission. The electromagnetic energy, which appears as gamma rays, is largely lost as we cannot "capture" and "use" it. The kinetic energy (mechanical energy) of the fission fragments is converted into thermal energy (heat) because the fission products are "trapped" in the fuel matrix and cannot "fly free" as they would in air. The thermal energy created in the fuel bundles heats the fuel, and the primary coolant picks up that heat and transports it to a steam generator. The steam generator turns secondary water into steam, and the steam is piped to a turbine. The thermal energy of the steam is converted into mechanical energy in the turbine, and the mechanical energy is transferred into a generator. The generator converts the mechanical energy into electrical (electromagnetic) energy, and that is the useful product we derive from nuclear fission.
