【If there are too much neutrons,a terrible thing will happen!】

《Atomic fission and fast neutrons》

However,it depends on whether how many neutrons a nuclear fission creates.The atomic nucleus doesn't always work as we humankind expect.💦

《The material of absorbing neutrons》

What we humankind can do is we deal with the generated neutrons.We can't control the neutrons one by one directly,but we can take more drastic steps.☝

Some chemical elements have strong nature in which they absorb the neutrons.We put the chemical elements in the nuclear reactor as the material of absorbing neutrons.When feeling there are too much neutrons,we make the material absorb the neutrons.We hush up the neutrons.😲

【The problem is the neutron's speed.】

The neutron has neither electric charge nor magnetism.It's,so to speak,a stone.The neutrons flit around,and are looking for a chance to collide with the atomic nucleus in an atomic reactor..🔥
