What happens when energy is released during atomic fission?

Nuclear energy is called the energy obtained by the transformation of atomic nuclei, so small and heavy clusters of particles inside the atom. Nuclear energy can be produced in two ways, by cleavage or synthesis of nuclei. Heavy nuclei of radioactive elements such as uranium or plutonium, can be split into two nuclei. By splitting are released from the nucleus of neutrons that collide with other nuclei causing them to split and subsequent emission of neutrons. This is called a chain reaction. The condition calls self-sustaining nuclear reaction is slowing down neutrons. For this purpose, a special substance, called moderator. The neutrons collide with the molecules of the moderator precipitate heating speed while the moderator. The resulting heat heats the water so that a couple who drives a turbine generating electricity. Another way of producing nuclear energy is nuclear fusion, in which nuclei combine to light elements. So far, fusion, however, failed to carry out so that it can be applied to the economy as a source of energy.

Atomic fission occurs when a neutron strikes a heavy nucleus such as uranium, causing it to split and release heat, radiation, and more neutrons. If this initiates a chain reaction, an enormous amount of energy is released due to the nuclear binding energy difference between the parent and daughter nuclei.
During atomic fission, the nucleus of an atom is split into two smaller nuclei, resulting in the release of a significant amount of energy. The forces holding the nucleus together are disrupted, leading to the release of energy. The process is initiated by a neutron that strikes a heavy nucleus like uranium, which then splits and releases heat, radiation, and more neutrons.
If these released neutrons cause further fission in other nuclei, a chain reaction occurs. This reaction can either be controlled, as in nuclear power plants to produce electricity, or uncontrolled, leading to explosive energy release as in atomic bombs.
The energy release is because medium-mass nuclei have a greater nuclear binding energy per nucleon than heavy nuclei. Thus, when a heavy nucleus like uranium undergoes fission, the resultant medium-mass nuclei have lost some mass, which, according to Einstein's mass-energy equivalence (E=mc²), is converted into energy. Approximately 1 MeV per nucleon, or around 240 MeV per fission event, is liberated as energy.

Energy released during atomic fission occurs when a heavy nucleus splits into lighter nuclei, releasing heat, radiation, and kinetic energy. The process can initiate a chain reaction, leading to more fission events and significant energy output. This energy is harnessed in nuclear reactors for electricity generation.
