We magnetically compress that fusion fuel.

我们用磁力压缩聚变燃料。

And the target has to focus the energy of the projectile into the fusion fuel.

并且目标必须将射弹的能量集中到聚变燃料中。

Just one kilogramme of fusion fuel produces as much energy as 10mn kilogrammes of fossil fuels.

一公斤聚变燃料产生的能量相当于一千万公斤化石燃料产生的能量。

The  fusion fuel, in turn, triggers fission within a so-called " spark plug" made from uranium  or plutonium.

聚变燃料反过来会引发由铀或钚制成的所谓“火花塞”内的裂变。
