福岛核事故后核电厂安全改进行动分析

Analysis of Nuclear Power Plant Safety Improvement Action After Fukushima Daiichi NPP Accident

介绍了福岛核事故后世界上主要核电国家相继开展的核电厂安全检查、再评价行动,并得出相应的检查和测试结论。法国、美国和中国等国家分别提出了福岛核事故后改进核电厂安全的建议、要求和行动,并制定了具体工程措施:在极端外部事件的设防,严重事故预防和缓解,水、电、通风实体改进,限制严重事故下的放射性释放和应急准备等主要方面开展的安全改进行动,将会提高核电厂的安全水平并提升缓解严重事故的能力。反思福岛核事故,总结福岛核事故对核电安全技术改进的促进作用,对未来核电安全技术的发展进行了展望。

The paper introduces nuclear power plant （NPP） safety inspections ,actions of re-evaluation and the main conclusions of the main countries with nuclear power in the world after the Fukushima Daiichi NPP accident .Countries ,such as France ,the United States and China ,carried out the NPP safety inspection and re-evaluation action ,and acquired conclusions . These countries respectively put forward the suggestions , demands and actions about improving NPP safety , and also formulated the specific engineering measures .The safety improvement actions ,such as fortification in extreme external events , severe accident prevention and mitigation , water , electricity and ventilation physical improvements ,limiting the radioactive release of severe accident , emergency preparedness ,and so on ,will increase the safety level and enhance ability to alleviate the severe accident of NPP .The profound consideration about the Fukushima Daiichi NPP accident , summarizing the promotion role of nuclear power safety＆amp;nbsp;technology improvement after the Fukushima Daiichi NPP accident , and the development of nuclear power safety technology in the future were discussed .
