Nuclear Energy

Nuclear energy, also called atomic energy, is the powerful energy released by changes in the nucleus (core) of atoms. The heat and light of the sun result from nuclear energy. Scientists and engineers have found many uses for this energy, including the production of electric energy and the explosion of nuclear weapons. Scientists knew nothing about nuclear energy until the early 1900's, though they knew that all matter consists of atoms. Scientists then further learned …showed first 75 words of 7764 total…

As the nuclear power industry has continued to develop, many improvements in plant equipment and operation have increased safety. Nonetheless, some experts insist that the next generation of reactors should take greater advantage of design features that rely less--or not at all--on mechanical equipment such as pumps and valves to remove heat if an accident occurs. Some of these reactors are known as passively safe reactors.
