I said them, not you
In all seriousness it's a job that somebody MUST do. I was hoping somebody like ROman Ibranovich (spelling?) would do it out of the goodness of his heart (given that it seems he is a tosser from what I have learnt). I know that robots at the time failed at the job (hence the army was brought in, many of which died) because of the radiation, however, let's talk now, with it roughly contained and with much better robotic abilities.
I suggest a huge perimeter be built using everything from robotic planes to land cranes etc. where possible. THis would be approximately 30metres thick of concrete and lead layers., no roof would be put on at first. Using helicopters specifically built for lifting blocks we now create several inner barriers, each of which get taller and have roofs placed on, again, very thick, supported by the inner walls. This layering system with air gaps will be good for the containment.
At the end of all of this a final large roof would be put on the total overal unit. Sensors will be laced within the whole building to try and dectect whether the system is working or not.
All of the machine would be custom built at a cost of billions or more. It should be made to last PROPERLY before it's too late. We know how to beat radiation (lead stopping a lot of it over a short distance it's just we don't yet have such equipment to put it into place safely. But it HAS to be done.
Then the surrounding area has to be considered....
This sort of idea has been suggested before just nobody wants to put the money in.
