New types of reactors were designed, including the Fast Breeder reactor powered by plutonium and cooled by liquid sodium.

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。

At the same time , CEFR is the first pool-type LMFBR(Liquid Metal Fast Breeder Reactor)using dacay heat removel system to.

另外，CEFR又是世界上首次在堆内采用非能动手段来排出堆芯余热的池式快堆。

The material at Dounreay is not waste, it is a nuclear material from the fast breeder reactor programme that requires appropriate management.

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。

With plutonium no longer needed for use in the world's abandoned fast breeder reactor programmes and nuclear powers getting rid of their atomic weapons, large stockpiles of the highly toxic plutonium metal are starting to build up.

In December 1995, the Monju fast-breeder reactor at Tsuruga sprang a leak in its sodium-cooling circuitry.

ECONOMIST: Japan

Also on Wednesday, the watchdog decided to freeze further steps to bring the Monju prototype fast-breeder nuclear reactor online, criticizing Japan Atomic its operator for a series of significant safety lapses.
