Non-renewable energy: (nuclear energy)

Nuclear energy is energy in the nucleus of an atom. Atoms are tiny particles that make up every object in the universe. There is enormous energy in the bonds that hold atoms together.Power generated from nuclear reaction is similar to that of fossil fuels because they all use heat to turn blades to generate power.A nuclear power plant uses uranium as fuel. Uranium pallets are combined into large fuel assemblies and placed in a reactor core.Uranium was first discovered by a German Scientist called Martin Klaproth in 1789. The chamber in which the fission takes place is called a Reactor. In this reactor, uranium fuel is assembled in such a way that a controlled fission chain reaction can be achieved. CO2 emissions from nuclear fuel is very low, even lower than hydro-power. Nuclear power plants are very expensive to build. It also produces very dangerous waste in the form of radio-active waste, even though the amount of waste is small. These are usually disposed of very deep underground where geological conditions are stable and far from human or environmental exposure.

In 2011, a tsunami struck Japan and caused problems with its nuclear power plant in Fukushima. Radioactive materials are very dangerous to humans and the environment.

There are laws that check that countries with unclear plants comply with safety rules and also do not misuse their plants for developing nuclear weapons.
