英国敦雷(Dounreay)原子能中心为进行核燃料的再处理,建立了马歇尔实验室,此举使欧洲商用快中子反应堆更为接近完成其所耗燃烧的循环处理工作。该实验室由二个实验室,一个已耗燃料实验室及一个分解燃料的大型处理室组成,其目的是处理被快中子反应堆使用过的燃料,从中提取钚元素,并使回收率达到99.5％。 The Dounreay Atomic Energy Center in the United Kingdom established the Marshall Laboratory for the reprocessing of nuclear fuel, which has brought the European commercial fast reactors closer to the completion of the cycle of their burning and combustion. The laboratory consists of two laboratories, a fuel-consuming laboratory and a large-scale processing chamber for decomposing fuel. Its purpose is to process the fuel used by the fast-neutron reactor and extract the niobium from it, and the recovery rate is 99.5. %.
