4. Introduction This historical timeline, prepared in 1993, traces the nuclear age from (1895-1993) the discovery of x-rays and radioactivity to the explosion of the first atomic bomb through the cold war to its thaw to the cleanup of the nuclear weapons complex.

5. Nuclear energy can be used to Make Atomic bomb Nuclear reactor Produce electricity Nuclear bomb Rocket

6. Make Atomic bomb If nuclear energy conversion takes place in a controlled manner, it can be used to generate electricity in a nuclear power station. If its energy conversion occurs in an uncontrolled way, like an atomic bomb, a hued amount of energy will be released during the explosion.

7. Nuclear reactor In 1993 there were 109 licensed power reactors in the U.S. and about 400 in the world. They generate about 20 percent of the U.S. electricity. (there are also a large number of naval power reactors.) The expansion of nuclear power depends substantially on politics, and this has come out differently in different countries. Very likely, after some time, the countries whose policies turn out badly will copy the countries whose policies turn out well.

8. Produce electricity in some countries, electrical energy comes from nuclear energy. Inside a nuclear power station, there is a nuclear reactor where nuclear fuels break down to produce heat energy. The heat energy turns water into steam, which drives a turbine generator to produce electricity. E.g. Daya bay power spation
