Nuclear energy has been used widely only for thirty years . In sixtieth it was an exotic source of power, researched by scientists, and widely discussed in press. Nowadays, as Ilan Lipper & Jon Stone state in their article about nuclear powers and society, it is the second largest energy source in the U. S. There are more than 110 nuclear plants throughout the U. S, and they produce more energy than hydropower, oil or gas, researchers write. For the U. S nuclear energy became a cheap and relatively safe source of energy, and many countries decided to adopt American experience in this field.Today most European and Asian countries have nuclear plants that provide them with energy. Nevertheless, a question emerges which is whether it is safe to grant access to nuclear powers to countries of the Persian Gulf, like Iran, who are known for being aggressive and searching for the means to get weapons. Politicians and usual people all over the world are discussing this question.
