Hope this isn't old news (I did a search) but I was reading up about Chernobyl the other day (as you do) and I spotted this - http://www.chornobyl.in.ua/en/chernobyl-2.htm . A huge metallic structure hidden in the woods nearby.
I also discovered some unexpected information. Nature in the Zone of Alienation near the reactor "seems to have not only survived, but flourished due to significant reduction of human impact. The zone has become a 'Radiological Reserve', a classic example of an involuntary park" (from Wikipedia).
In a bizarre way, 20 years after the accident, Chernobyl has become a beautiful place out in the country.
