Chernobyl's Sarcophagus, Redux
Lasrick (2629253) writes "With the news that a multinational consortium is to the halfway point in constructing a huge stainless steel hangar that will sit over the ruined site of the Chernobyl nuclear reactor, Dan Drollette looks in the archives of the Bulletin of the Atomic Scientists and compares notes on the sarcophagus that was built 25 years ago, and the one that is being built now. 'No one really knows what went into the "concrete cube;" even the amount of concrete claimed to have been used is suspect, as it would form a volume larger than the sarcophagus, wrote nuclear engineer and author Alexander R. Sich in his 11-page article, "Truth was an early casualty."' Let's hope this new sarcophagus lasts longer."
If by taking responsibility you mean reburying the highly radioactive blob and unspent fuel which will continue to work its way to their water table...then yes they are.
A true example for the rest of the world.
The truth is we can't adequately cope with runaway reactions of any scale. The best we can do is try to keep the scale small which doesn't produce enough power to be useful. We also don't have a solid plan on what to do with the waste products besides weapons proliferation.[lots of ideas, no solid plans]
Nuclear energy is clearly something we are all bad at.
On a positive note, deeds such as this involving international assistance reinforce my retarded optimism that humanity might rise above tribalism into something astonishing.

The core melted a hole through the ground deep enough to hit the water table where it exploded on contact with water, then caused a steam explosion that was so powerful some of the material hit the jet stream. The heat continued causing hydrogen build up and further hydrogen explosions.
They tried to pour molten lead into the cavity but that just boiled and caused the radioactive steam to also carry lead vapor as well, making it even more toxic. So they gave up and filled it in with concrete. No one has any idea how large the whole was, if there was a chamber at the bottom from the water reservoir or multiple explosions. I don't find it the least bit suspicious that the amount of concrete poured into a random unexplored hole in the midst of the greatest man made disaster in history might be a bit off.
Please cite sources for the core melting through to the water table. Accounts that I've seen say the steam explosions are from the cooling loop and secondary explosions are due to hydrogen. Most of the dispersal was due to the fire which burned for days.
Yep, but the core didn't hit the water table. They located most of it years and years ago. The core is currently a solidified mass through a bunch of pipes, solidified pools, and such through much of the structure under where the reactor core was, the best known formation is the 'elephant's foot' located in a sub-basement.
Taking pictures of it was an interesting affair because the radiation is strong enough to fry even our best shielded robots, not that the Russians had them, so they had to get creative with more primitive tools.
Still, I haven't seen any evidence that it managed to make it to the water table.
