A while ago I watched a documentary on building the sarcophagus which encloses the Chernobyl Nuclear disaster site. I have unsuccessfully, tried to find that documentary as my recollection runs that the radioactivity released from the Chernobyl site was only able to be stopped by burying the reactor core in sand, concrete and an outer shell called a sarcophagus.
There seem to be parallels with the current Deepwater Horizon disaster in that we are witnessing once more that man is capable of unleashing uncontrollable forces in his pursuit of energy. Forces he had no contingency plan to deal with. Forces capable of devastating economies, destroying livelihoods and killing wildlife by contaminating the environment to such an extent that even people find they have to move away rather than suffer.
That the only way that we have to fix it once that bottle is uncorked, was to just bury it in concrete. In Russia the reactor core was covered in sand then concrete. In the Gulf of Mexico disaster, first mud was tried, but once the relief wells are drilled, it will be likewise be filled with concrete.
Based on this I went looking for supporting evidence to back up this initial premise, and am astounded by what I found.
