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.
Boron Carbide.

Uranium and most transuranic elements. Plutonium and Americium are particularly good reactor fuels.
A nuclear reactor is a plant which deliver electricity and (or) heat.The function principle is the release of energy from nuclear fission of fissile materials as the isotope uranium-235.
It contains a model nuclear reactor. It used to be double this price.

Steel, borated concrete, lead, etc.

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.
The pressurised water reactor (PWR)

Most often, light water (H2O) is used as a moderator in a nuclear reactor. Sometimes, heavy water (D2O), or graphite is used.
