敦雷的原料不是废料，而是来自快中子增殖反应堆计划的需要适当管理的原材料。
The material at Dounreay is not waste, it is a nuclear material from the fast breeder reactor programme that requires appropriate management.
新型的反应堆被设计出来，包括由钚提供能量，液态钠参与冷却的快中子增殖反应堆。
New types of reactors were designed, including the Fast Breeder reactor powered by plutonium and cooled by liquid sodium.
敦雷曾是英国研发快中子增殖反应堆——目的在于消耗燃料的同时生成新燃料——的中心，直到1988年该项目取消。
Dounreay was the UK centre for developing fast breeder reactors, which aimed to create new fuel as they consumed it, until the programme was cancelled in 1988.
对于堆芯内布置不同燃耗深度的燃料元件的反应堆，应用本模型可以估算堆芯燃耗物理参数如：堆芯中子增殖系数、燃料元件燃耗增值等。
For reactors loaded with fuel assemblies of different burnup, the evaluation model can te used to calculate core physical parameters such as core neutron multiplication factor, burnup increment, etc.
我们已经使用了一个相对简单的词语，称为，中子的增殖系数，那就是K，如果K等于1，中子数，是稳定的，裂变速率也一样。
And we've used a relatively simplistic term called neutron Multiplication Factor which is the K that if the K equals one the neutron population is steady as is the fission rate.
