So if we start up here, fast neutrons produced by fission, by thermal fission and then you add the total number of fast neutrons produced.
如果我们在这开始，生产的快速中子,通过裂变，通过热能裂变,你加入生产的快速,中子的全部数量。

And you can see a very high energy as uranium 238 does have a fission cross section which in some ways can be used in fast reactors.
你能看到铀238有很高的能量8，有一个横截面在一些方式下，能够用于快速反应堆中。

Such reprocessing-or even fast-neutron reactors that don't use water to moderate fission and can potentially create more fuel than they consume-remain a distant prospect.
