【The disaster of a fast-breeder reactor,もんじゅ】

The sodium has a property which is suitable for the fast-breeder reactor as coolant.In the fast-breeder reactor,the high speed sodium makes the plutonium of nuclear fuel cause atomic fission,and creates large amount of energy.😃

To my surprise,after the plutonium burned,it doesn't decrease,but increases.The sodium doesn't reduce the neutrons' speed,so the workers used to adopt it.

The coolant for the fast-breeder reactor is requested the next conditions.☝

①It transmits heat to other substance.

②Its concentration is comparatively low.

③It absorbs few neutrons.

④It doesn't reduce the neutrons' speed.

⑤Its price is low.

However,it doesn't always mean that the sodium has no demerits.When passing through a reactor core,it will be covered with radiation,and it reacts with water or oxygen easily.Explosions bring about sometimes,so it's very perilous🔥
