【How do we get the uranium?】

《Isotope of the uranium》

Uranium 238 commands in the whole uranium overwhelmingly,but no atomic reactors working all over the world use the uranium 238 as their fuel.Instead they adopt the uranium 235.😃
　　　　　　　　　
Some nuclear reactors use plutonium in order to create atomic bombs.Except for them, density of the uranium 235 has to be raised up to several percentages.We call the operation of raising the density of the uranium 235 enrichment 濃縮.☝

《Gathering the uranium》

How do we pick up the uranium and process? How do we turn it into nuclear fuel?😲

Uranium is melted into the sea water,though it's low concentration.If uranium mine is exhausted in the future,we'll consider its extraction from the saltwater,but it's been gathered from the uranium mines at present.😃

Pitchblende and 人形石 are well-known uranium mine.The pitchblende is famous for the one Mrs.Curie discovered polonium and radium.The 人形石 is being gathered in an area which is famous for the deposit of uranium.😃
