Which are also very key parameters because the higher these Numbers are the more neutrons are produced per fission.

那些是关键的参数，因为这些数目越高，每个裂变产生的中子就越多。

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。

The solid fuel pellet (a ceramic oxide matrix) is the first barrier that retains many of the radioactive fission products produced by the fission process.

固体的燃料弹（陶式氧化物母体）是第一道防护，隔开裂变过程中产生的裂变放射。

Xenon-133 is a radioactive noble gas produced during nuclear fission that poses no concern at the detected level.

FORBES: EPA Sounds an 'All-Clear' (so far) for Western U.S.

Fusion is the process of forcing the nuclei of atoms so close together that they fuse into a nucleus of a new element. (Fission, of course, is the opposite: energy produced by splitting nuclei.) The new, fused nucleus weighs less than the original two.

FORBES: A Nuclear Hybrid

Reactors that exploit nuclear fission (in which energy is generated by splitting uranium atoms) have produced thousands of tonnes of spent fuel and other radioactive by-products.
