一、核能发电现状与前景1．1938年秋，科学家发现铀235原子核在中子轰击下，可发生裂变，并释放出大量能量，从此人类进人了原子时代。核能的利用经过半个世纪的发展至今，目前世界上核电站装机容量已达3．5亿千瓦。人们已普遍认为，核能是一种经济、清洁、安全、可靠的能源。2 First, the status quo and prospects of nuclear power generation In the autumn of 1938, scientists discovered that the uranium 235 nuclei under the bombardment of neutrons could undergo fission and release a great deal of energy. Since then humans have entered the atomic age. The use of nuclear energy has developed over the past half a century. At present, the installed capacity of nuclear power plants in the world has reached 350 million kilowatts. People generally believe that nuclear power is an economical, clean, safe and reliable source of energy. 2
