从世界上第一座核电站建成至今,经过30多年的发展和改进,核能已成为世界上一种重要能源,到1988年底为止,世界上已有26个国家和地区的428座核电厂在运行,累计4828堆年,总装机容量为309.4GWe,核发电量占世界总发电量的16%,有些国家的核发电量已占其本国总发电量的50—70%。由于电站的系统复杂、投资高、建造费用和周期难以确定,特别是三里岛 Since the establishment of the world’s first nuclear power plant, nuclear power has become an important energy source in the world after 30 years of development and improvement. By the end of 1988, 428 nuclear power plants in 26 countries and regions have been operating, A total of 4828 heaps of yards have a total installed capacity of 309.4GWe. Nuclear power generation accounts for 16% of the world’s total generating capacity. In some countries, nuclear power generation accounts for 50-70% of its total generating capacity. Due to the complex system of power plants, high investment, construction costs and cycles difficult to determine, especially three Mile Island
