Abstract
A grade-7 nuclear leakage accident has happened in Fukushima nuclear power plant (Japan), which followed the magnitude-9.0 earthquake on March 11,2011, in Japan, and has been in focus worldwide now. This paper introduces the course of the accident, and analyzes its causes, impact and reflection. The inducements of the accident are obviously the earthquake and its resulted tsunami, but the causes in deep are very complex. In terms of technology, the causes are mainly summarized in the paper as three aspects - the second-generation nuclear technology adopted by the plant, the plant design not enough for earthquake proof, and the nuclear power unit 1 has being in operation over its design life time. In comparision of design, performance and technology on the third-generation technology AP1000 and EPR (Europe presure water reactor), it proves that AP1000 is better in securty than EPR. Aiming at the situation of the second and third generation nuclear technologies coexisting in China, the paper discusses the safety supervision system, the development direction of the chief reactor types of nuclear power, the emergency linkage mechanism, and the emergency preplans for the nuclear plants in China.关键词
