地震一直是世界核能界时刻关注的事。在核动力发展初期,地震知识十分有限。但是在过去30年中,人们对地震行为的理解,以及可用来更准确地测量许多地震现象的仪器和方法已大大增加。新知识已促使许多核电厂的安全屏障得到加强。例如,作为一个大型的美国评估计划的结果,易发生地震的加利福尼亚州迪亚布洛 Earthquakes have always been a concern of the world’s nuclear community at all times. In the early stages of nuclear power development, knowledge of earthquakes is very limited. However, in the past 30 years, people’s understanding of earthquake behavior and the instruments and methods that can be used to measure many seismic phenomena more accurately have greatly increased. New knowledge has helped to strengthen the safety barriers in many nuclear power plants. For example, as a result of a large U.S. evaluation program, Diaslo, California, prone to earthquakes
