If you wanna just take a quick look at a breeder reactor, we have either mixed oxide or plutonium oxide. There's a blanket region in which you can make plutonium using uranium 238.

如果你想快速观察一个增值反应堆，我们就可以得到混合氧化物或者二氧化钚，有一个空白的区域，那里你们能用铀238得到钚。

The fuel in No. 3 is a blend of plutonium and reprocessed uranium, referred to as MOX (for mixed oxide) and manufactured by the French nuclear company AREVA. MOX fuel rods are also less stable than plutonium-free rods.
