美国电力工业已悄然跨越一个里程碑：核电生产成本已降低到同行业的最低水准，而且，安全技术和运行方式的改善已将核电的“发电能力利用系数”(实际输出功率与潜在输出功率之比）提高到90%。 20年来，核电厂的生产成本一直在下降，1999年，美国核电厂平均每千瓦时电的生产 The U.S. electric power industry has quietly crossed a milestone: the cost of nuclear power production has been reduced to the lowest level in the industry, and improvements in safety technology and operating methods have resulted in nuclear power’s “utilization capacity utilization factor” (the ratio of actual output power to potential output power). ) Increase to 90%. In the past 20 years, the production cost of nuclear power plants has been declining. In 1999, the average production per kilowatt-hour of nuclear power plants in the United States
