Nuclear fusion does not currently occur in nuclear plants. Nuclear plants use nuclear fission, where atoms are split to release energy. Fusion reactions, in which atomic nuclei combine to release energy, are not yet used commercially for electricity generation.
It's really just a matter of degree, all reactors produce some power. Those used in a power plant will produce perhaps 3000 to 5000 Megawatts thermal. Low power reactors producing a few kilowatts are used for experiments, teaching in universities, and for producing radioisotopes by irradiating samples, but reactors in this sort of power level would not be harnessed to produce electricity, the heat produced if large enough would be removed and rejected to the atmosphere or to a water cooling circuit. This makes them simple to operate and to start and stop as required.
Nuclear fission occurs in the reactor core of a nuclear reactor. This is where nuclear fuel, typically uranium, is arranged in such a way that it sustains a chain reaction of splitting atoms, releasing energy in the process.
At the center, where the gravitational pressure is highest.
These are not chemical reactions but thermonuclear reactions.
Nuclear energy is produced in the core of a nuclear reactor, where controlled nuclear fission reactions occur. These reactions release heat energy, which is then used to generate electricity through steam turbines.
Fuel cells in a nuclear reactor are the structural components where nuclear fission reactions occur, generating heat. This heat is used to produce steam, which drives turbines to generate electricity. The fuel cells contain the nuclear fuel (such as uranium) and control rods to regulate the nuclear reactions.
The chain reaction in a nuclear power plant occurs in the reactor core, where nuclear fission reactions take place. Heat generated from these reactions is used to produce steam, which then drives turbines to generate electricity.

Nuclear fission reactions typically occur in the core of a nuclear reactor. This is where the fissionable material, such as uranium-235, is bombarded with neutrons, causing the nuclei to split and release more neutrons and energy in a chain reaction.

One type of nuclear reactions is fusion. This usually occur under extreme conditions - extreme temperatures and pressures. This most commonly occurs in the center of stars (including our Sun); in some cases also on the surface of a star (when matter falls onto the star, temporarily producing the high temperatures required). So far, it it not economically practical to do this artificially (search for "fusion reactor") - except for the destructive H-bomb. Fusion reactions usually occur if sufficient amounts of Uranium or some other heavy elements come together. This is the case with a nuclear reactor, and an atomic bomb.
In the PWR and BWR types it is a matrix of fuel assemblies stabilised with zircaloy fittings, and with control rods in certain specified channels within this matrix. This is where the nuclear heat is generated, and this heat is carried away by a flow of very pure water circulated by large pumps and at a high pressure.
Nuclear fission takes place in the nuclear fuel rods that are placed in the reactor core that is situated in the reactor pressure vessel. The reactor pressure vessel is usually situated inside the reactor containment.
A radioactive core is the central part of a nuclear reactor where nuclear fission reactions occur. These reactions release a tremendous amount of energy that is used to generate electricity. The core is typically made up of fuel rods containing radioactive materials such as uranium or plutonium.
A dangerous condition caused by overheating inside a nuclear reactor is called a nuclear meltdown. This occurs when the reactor core is unable to be cooled and may result in a breach of the containment structures, releasing radioactive material into the environment.
