What is nuclear energy and what is used to make nuclear energy?

Answer 1

Atoms that are large,radioactive and contain extra neutrons are known as unstable isotopes. Uranium 235 and Plutonium are two souces of nuclear fuel. If these large nucleii are hit by a neutron travelling at a certain speed they are likely to split into two smaller atoms along with release of heat energy and two or more new neutrons. If this process is allowed to continue unchecked in a quantity of the element larger than the critical mass it explodes violently.

If the reaction is controlled by mopping up neutrons with a moderator it can be controlled and to continue at a set level maintained in a nuclear reactor. The heat of the chain reaction is removed by passing a coolant through the reactor core and this heats water to steam to drive electrical turbines generating electricity. The nuclear material eventually becomes spent and has to be replaced. It is this spent fuel, still highly radioactive, that is the main problem with nuclear power. Also decommissioning of an old nuclear reactor can be as expensive as the cost of all the electricity generated during it's lifetime.

Answer 2

There are two types of nuclear power. Fission and fusion. With fission power, (the type most power plants use), controlled atoms split apart and give off energy. In fusion, (very difficult to do, mostly working for only a few seconds), controlled atoms fuse together and give off energy. Fission is easier to make than fusion power. Fusion power lasts longer and is the power of the Sun.

Answer 3

technically its not made by anywhere is comes from inside a atom...
