摘　　要：发展快堆可将铀资源的利用率从单发展压水堆的1％左右提高到60～70％。美、英、法。德、日、俄、印等国发展快堆已有30～50年的历史。中、韩和巴西亦已开始了快堆计划。全世界共建成大小20座快堆,技术已近成熟。经验已经证明,快堆是安全、可靠的,并有良好经济前景。八十年代起,主要核国家开始注意长寿命稀有锕系核素问题,快堆用于烧锻和核电厂来的过剩钚和军用钚有其有利之处。快堆可以设计成增殖堆,也可设计成烧锕或烧钚的燃烧堆。未来三四十年,这些发展快堆的国家将按自己的需要实现这两种应用。By development and deployment of fast reactors the utiligation of uranium resources could be increased from about 1% based on pressuriged water reactors up to 60 ~ 70% . US, Russia, UK, France Germany, Japan and India have developed this Technology for 30-50 years. China, Korea and Brasil have started their own projects of fast reactor technology. Twenty fast reactors in different sige have been built up in the world. The fast reactor technologe has been near mature. It is proved that a fast reactor would be safe, reliable and will be competitivable in economy in future. Since 1980 s the main nuclear Countries have started to pay great attention on the long-lived minor Actinides. The fast reactor has its marits to burn them and excess plutonium from nuelear plants and from disarmament. A fast reactor could be designed as a breed or as a burner. In coming 30~40 years, both types of fast reactor will be further developed by the Countries as they need.
