【What should we do in order to convey heat created with the atomic reactor?】

《Candidates for conductor of heat.》

In addition,a large amount of heat have to be carried wit the conductor of heat so efficiently that it flows very quickly.😃

Therefore,in an ordinary sense,if a matter for the conductor of heat is heavy,to be exact,it means when its density is very high,pipe laying for the conductor of heat will be forced to be thick,so it isn't realistic.Needless to say,if it burns easily,it isn't desirable at all.🙅

《The conductor of heat serves as a material of moderator》

As a result,the most appropriate the conductor of heat,or the refrigerant is water,or heavy water.Instead of hydrogen,heavy hydrogen is used for the heavy water,especially the heavy hydrogen which doesn't absorb neutrons very much.🙆

However,the heavy water is both little and expensive,so we usually adopt light water for the refrigerant.Then atoms of the hydrogen work as a moderator for the neutron,so it's very useful.👍
