Quick Answer: What is a nuclear reactor simple definition?

What is a nuclear reactor easy definition?

nuclear reactor. A device used to generate power, in which nuclear fission takes place as a controlled chain reaction, producing heat energy that is generally used to drive turbines and provide electric power. Nuclear reactors are used as a source of power in large power grids and in submarines.

What is a nuclear reactor kid definition?

A nuclear reactor is a machine that uses fission to generate heat. There are different designs which use different fuels. Most often, uranium-235 or plutonium-239 are the main components of these fuels. Most nuclear reactors are used to make electricity.

What is a nuclear reactor answer in one sentence?

A nuclear reactor is a container in which nuclear fission or nuclear fusion happens in order to produce energy. Nuclear reactors have systems to close down nuclear fission if unsafe conditions are detected. Fuel rods containing uranium are placed next to each other in a vessel called a nuclear reactor.

How does a nuclear reactor work?

Nuclear power plants use heat produced during nuclear fission to heat water. … The heat produced during nuclear fission in the reactor core is used to boil water into steam, which turns the blades of a steam turbine. As the turbine blades turn, they drive generators that make electricity.

How hot is a nuclear reactor?

Here is another important part of reactor technology: The temperature reached in a nuclear reactor is in the range of 300 degrees Celsius. This is higher than the usual boiling point of water, 100 degrees.
