Nuclear energy has sometimes been called "the double-edged sword of science." That phrase reflects the fact that nuclear energy can be used for both useful and constructive purposes and for deadly and destructive ends. Indeed, the context in which the world was first introduced to nuclear energy was the latter, when nuclear energy was used to produce the most destructive and terrible weapons the human race has ever seen. Nuclear scientists have always promised the general public that nuclear energy has many potential positive benefits also. Almost certainly, the greatest potential benefit accruing from nuclear energy is the availability of an almost endless and environmentally attractive source of power. The generation of nuclear power, however, also creates issues of safety and radioactive waste. Nuclear Power provides readers with clear and essential information needed to define, understand, and research these important issues.

Nuclear power plants do not emit carbon dioxide while generating electricity but they do produce radioactive waste that must be disposed of safely. Safety is also a crucial factor because an accident at a nuclear power station can release radioactive material into the environment and this ... Nuclear power reactors produce energy by initiating and controlling a sustained nuclear chain reaction.

The USA is the world's largest producer of nuclear power, accounting for more than 30% of worldwide nuclear generation of electricity. Following a 30-year period in which few new reactors were built, it is expected that 4-6 new units may come on line by 2020, the first of those resulting from 16 licence applications made since mid-2007 to ...
