【What is the chain reaction?】

《Chain reaction which branches off》

Then the atomic nucleus which is undergone fission in the first reaction is just a one,but two neutrons collide with two atomic nucleus in the next reaction,so more two neutrons are generated.Its number become 4,after that 8,16,…🔥

The neutrons increase infinitely,so it's forced to explode.We call the phenomenon not just the chain reaction but the one which branches off.😃

When leaving the atomic fission of uranium 235 alone,a great erruption breaks out,for the number of the neutrons in the one atomic fission branch off,continue to increase more than one.⚠

【Is the criticality 臨界 a terrible phenomemnon?】

There is an amount of criticality among very serious words in relation to the atomic fission.If matter which automatically breaks out chain reaction branched off like the uranium exceeds the amount of critically,it causes the chain reaction voluntarily,even if we do nothing wrong.💀
