【How do we concentrate the uranium?】

《Concentration.》

We take out the central part,it means the light one,and put it on the centrifuge 遠心分離器 again.We have to repeat the monotonous work like that so as to concentrate the uranium.😩

《Enriched uranium and 劣化 one》

We call the concentrated uranium 235 enriched one.Splendid stages on which as the fuel for the atomic reactor plays an active part waits for the enriched uranium.😃

Contrary to it,we call the uranium 238 劣化ウラン,and it's forced to be an obscure one.It may be used as the fuel for a fast-breeder reactor 高速増殖炉 in the future,but its experimental reactors have never obtain desirable result at all.🙅

For example,a critical nuclear accident occurred in 常陽,and other accident of having leaked sodium in もんじゅ.😒

We used to call the sodium natrium before.

Uranium 238 has been used as shell and so on at present,for it's by far higher than iron in relation to special gravity 比重💧
