What is nuclear energy? That energy is the result of nuclear reactions, in which matter is converted to energy. We have been able to harness that mechanism and regularly use it to generate power.

Nuclear reactions Changes can occur in the structure of the nucleus of the athoms. These changes are called nuclear reactions. Energy created in a nuclear reaction is called nuclear or atomic energy. Nuclear energy is produced in two different ways: Naturally: Some nuclear energy, like the Sun produces heat and light by nuclear reactions. Man-made: Machines called nuclear reactors, parts of nuclear power plants, provide energy for many cities. It also occurs in the explosion of atomic and hydrogen bombs.

Production Nuclear energy is produced in two different ways: Nuclear Fusion: In nuclear fusion, the nucleus of atoms are joined together, or fused. This happens only under very hot conditions. The Sun and the hydrogen bomb works by nuclear fusion. Nuclear fission: In nuclear fission, the atoms are split, causing energy to be released. The atomic bomb and nuclear reactors are work by fission. The uranium is the main fuel used to undergo nuclear fission.

History of nuclear energy December 2, 1942: The Nuclear Age began, by the first chain reaction in a pile of uranium. August 6, 1945: The United States dropped an atomic bomb on Hiroshima, Japan. November 1, 1952: The first large version of the hydrogen bomb was exploded by the United States. February 21, 1956: The first major nuclear power plant opened in England.

NUCLEAR ENERGY IN ANDALUSIA In Andalusia, they aren't any nuclear power plants because they think that this type of energy is very dangerous, so they musn't produce it.
