Most nuclear reactors are built to produce electric power. A single nuclear reactor can generate enough energy to power 1,200,000 homes around the clock. The vast minority of reactors around the world are operated by power or energy companies that are licensed by the government, or by the government itself.
Some smaller reactors are constructed for research, and for the production of nuclear materials used in industry and medicine. Plutonium can also be produced in reactors, and its application as a nuclear fuel or a material for a nuclear weapon is widely known.
Nuclear fission of fissile isotopes of uranium and plutonium release an enormous quantity of energy; in the future the nuclear fusion will be used.
Not a nuclear reactor!
This is used in the nuclear reactor that is known as Boiling Water Reactor (BWR) in which heat produced by the nuclear fission in the nuclear fuel allows the light water reactor coolant to boil. Then, the nuclear reactor moisture separator is used to increase the dryness of the produced steam before it goes to the reactor steam turbines.
Typically, Uranium-235 is used as fuel in nuclear reactors.

In most reactors in the world, water is used to absorb heat released from the reactor.

Never a nuclear reactor is used in airplanes. However, it is used in submarines.
Boron is used inside a nuclear reactor inside a control rod which is used to 'soak' up the neutrons inside the nuclear reactor, a control rod can be used to control the rate of fission inside a nuclear reactor.

A Nuclear Reactor.
Most often, light water (H2O) is used as a moderator in a nuclear reactor. Sometimes, heavy water (D2O), or graphite is used.
The used fuel in a nuclear power plant is the nuclear fuel being discharged from the nuclear reactor after being irradiated during reactor operation. It is usually composed of trans-uranium heavy elements, a wide variety of fission products (that resulted from the nuclear fission processes in the nuclear reactor) and products of radioactive decay (produced before and after fuel discharge from the nuclear reactor).
Typically, Uranium-235 is used as fuel in nuclear reactors.
