Some are talking about burying the plant under concrete, my issue with that, is that first it never worked in Chernobyl, second there are many reactors here and they would letting them all melt down under the concrete, which would then heavily pollute the earth below all the waste rods and the current active rods would melt. Third or fourth that Japan is a tiny island and shouldn't have any amount of it's land lost.
So my question is what do you all think the best answer is here?
It worked reasonably well in Chernobyl. The problem there is mainly the radioactive material that escaped before they could plug it with concrete.
There's no reason that the reactors will melt down. The nuclear reactors have been shut down since before the tsunami stuck. They are now kept warm by the decay heat of the waste products. This decay heat will dissipate reasonably quickly. After that there's no heat source to melt them so, as long as they wait a while before pouring the concrete there's no chance of a melt down.
Once it's buried under a layer of concrete there's no reason, in principle, why you couldn't re use the land. Since it will obviously be a hill, perhaps one use for it would be as "high ground" for people to run to if there's another tsunami.
Never trust anyone who is introduced by the media as someone with a book to sell.
In any event, we will see what happens. Presumably, if they close down the plant without the predicted "fire and brimstone" you will come back and apologise.
