1.引言 1951年美国建成的世界上第一座发电的实验快堆(EBR-I)证实了快堆增殖的可能。1964年美国又建成了另一座实验快堆(EBR-II),其目的是为验证带有蒸汽发电厂和闭路燃料后处理循环设施的钠冷快堆的工程可行性,经过几年的运行,达到了上述目的。实际上这就是一体化快堆的雏形。作为快堆的堆芯燃料,在堆的发展中使用了不同类型的燃料元件,在五十年代,为达到高的增殖比而采用金属
1. INTRODUCTION The first experimental fast reactor (EBR-I) in the world built in the United States in 1951 confirmed the possibility of rapid reactor proliferation. In 1964, another United States Experimental Fast Reactor (EBR-II) was built to verify the feasibility of engineering a sodium-cooled fast reactor with steam-fired power plants and closed-loop fuel aftertreatment facilities. After several years of operation, Achieve the above goal In fact this is the prototype of an integrated fast reactor. As a fast reactor core fuel, different types of fuel elements were used in the development of the stack, and in the fifties metal was used to achieve high growth rates
