1) Introduction:
a) Hook: Nuclear energy should be limited
b) Back ground information: Nuclear energy is produced during reactions in the nucleus of an atom. Atoms can be thought of as miniature solar systems with which the nucleus at the center like a sun and electrons orbiting around it like planets. Densely packed neutrons and protons make up the nucleus, which is held together with grate force, the “strongest force in the nature.” When the nucleus is bombarded with a neutron, it can be split apart a process called fission. Uranium is the heaviest natural element and has ninety-two protons because uranium atoms are so large, the atomic force that binds it together is relatively weak, so fission is more likely than other elements. In nuclear power plants, neutrons collide with uranium atoms splitting them. This split release neutrons from the uranium that, turn, collide with other atoms, causing a chain reaction. Fission release energy that’s heats water to approximately 520ºF in the core of the plant. The steam that is created is then used to spin turbines that are connected to generators, which produce electricity. c) Environmental damage and Nuclear weapons are the defects of nuclear energy 2) Body I: Nuclear waste did not begin to be generated in large quantities until after the World War II (1939-1945), when several nations began building thousands of nuclear weapons along with scores of nuclear power plants to generate electricity. Because national survival was thought to depend on building atomic bombs, radioactive waste was treated as unimportant. As a result, poorly contained wastes were created by weapons programs. In 1954, a chemical explosion at a Soviet (now Russian) waste- storage site at Kysthym in southern Ural Mountains contained about 5,800 square mi. (15,000 square km) and forced the evacuation of over 10,000 people. The Soviet Union denied that the event had occurred until 1989, and reports of hundreds of deaths from the accident...
