initially inside a nuclear reactor, uranium fuel such as uranium 235 is lowered inside the reactor and excess neutron is released, which is then absorbed by the uranium fuel and it atomically becomes unstable, so it splits into two smaller nuclei and more excess neutrons released. Again the same reaction occurs and splitting the nuclei into more smaller nuclei until it dies of or becomes atomically stable, the result of this is chain reaction.

It is produced in the fuel rods by fission of the U235 nuclei. Each fission produces a certain amount of heat, and this is transferred to the water or gas which is pumped past the fuel, by contact heat transfer.
"fission"
Fission
Nuclear fission.
Energy contained in bonds within a nucleus that is converted to kinetic energy.
It comes from the fission of certain nuclei, mostly U235 and Pu239. Every fission of a nucleus of an atom of these materials releases a certain amount of energy as heat.

When an atomic nucleus fissions, it splits into smaller atomic nuclei. These smaller atomic nuclei are referred to as "fission fragments." The unstable nucleus of a radioactive element can fission (split) into smaller nuclei, i.e. those of lighter elements. This can also release other atomic particles, as well as energy. In nuclear power and atomic weapons, the fission process is initiated to release the nuclear energy. Natural fission is a much rarer occurrence than radioactive decay.
Some nuclei, notably U235 and Pu239, can be made to cause a chain reaction where neutrons are produced in nuclear fission, and propogate more subsequent neutrons so that a steady rate of fissions can be achieved. Each fission releases an amount of energy in the form of heat, which is then used in generating plant similar to that in a fossil fuelled power plant.

The splitting of an atomic nucleus into smaller nuclei is called nuclear fission.

"fission"
Nuclear fission is defined as splitting large nuclei into smaller ones.
Good question. A fusion bomb combines (fuses) light nuclei (hydrogen) into larger nuclei to get its energy. But it needs a fission bomb to start it. A fission bomb breaks up (fissions) heavy nuclei (uranium/plutonium) into smaller nuclei to get its energy.
Yes, the results of nuclear fission include the production of lighter nuclei. The originating atom has split into smaller pieces.
