radioactive materials used are materials that can ungergo a process knows as fission.

when, for example, uranium is purifiedit emits neutrons, these neutrons hit other uranium atoms and cause them to do the same but they emmit 2 neutrons.

if the sample of uranium is large enough (a quantity known as "crittical mass") the neutron interactions cause a chain reaction and generates heat as well as a significant increase in the rate of radioactive decay (to put it simply).

this chain reaction can get out of hand and can cause an accident, such as the one at chernobyl and this causes a "meltdown" where the reaction becomes uncontrolable and releases enormous quantities of radiation.

to prevent this occurring "control rods" are used. these are rods of neutron-absorbing material that can be lowered into the uranium and prevent the system from getting out of hand (hence the phrase "control rods"). as the excess neutrons are absorbed they do not interact with the uranium.

the heat that is generated by the uranium is transfered to a coolant (normally liquid CO2) and this heat is then transfered to a boiler where it boils water (this way the water never comes close to the radioactive uranium and is safer) the boiling water produces pressure which is used to turn turbines which generate electricity.

it is also worth noting that a nuclear power station does not generate CO2.
radio active substances produce heat. The heat is used to raise the temperature of water to produce steam. The steam is directed (at high pressure) onto the blades of a turbine causing it to rotate. The turbine drives a generator which produces electricity which is fed into the grid.

Uranium is used as the nuclear fuel in nuclear power plants. Uranium, unusally in the form of its oxide, is welded into fuel rods or plates, and the rods or plates are welded together in bundles.

How is nuclear energy used beside in power plants?

Though power plants are, perhaps, the most important use of nuclear energy, there are a lot of others. Radioactive substances are used in for variety of industrial and technical functions. The most common of these is possibly the use of radioactive materials in smoke detectors. Also, nuclear emissions are used for measurement, such as of the thickness of things otherwise difficult to measure,, or for imaging. There are important uses for radioactive substances in medicine. Some of these are used for diagnosis, such as in imaging. Others are used in therapy. Also, whether we like it or not, nuclear energy is used in nuclear bombs.
