Really fascinating. I go quite often to Kiev and have debated getting a guided tour of the Chernobyl site and surroundings (organised). Kiev itself is a very beautiful city with wonderful women!

OMFG 
Cetainly makes you think..... The pictures of the creche won't leave my mind for a very long time
Ironically, I presume the guys who pushed the button is out of prison now......
Agreed though - Nuclear Power is deffo the way forward. It's just a shame that the dangers are just as potent as the advantages.......

One day in the distant future they will have to start digging coal out of the ground again. They may have to use scrubbers etc to get rid of the greenhouse gases etc though.

Pictures do bring home the human factors of the tragedy.
There's a little bit more to the cause of the original incident than the comments on that site - or here - fully tell. Lack of understanding of Xenon poisoning - especially when trying to restart a reactor much too quickly, positive reactivity coefficients, and poor control rod design were also contributing factors. The disabling of 6 (IIRC the numbers correctly) different safety systems, in a chain of events subsequent to the original tests was the thing that set it off, but putting any one of the other factors right would also have prevented the disaster.
Think it is fair to say that the person who pressed the button was not truly the guilty party, as I don't believe in any way it was an informed decision made with free will. It might be interesting to learn what happened to the people who gave the orders (who may well have been far away from the effects).
There are a very large number of design factors which prevent that kind of event occuring in UK reactors (although these factors vary from Magnox to AGR to PWR, which are the three reactor types in the UK). It would have been almost impossible with the Russian reactors, but if you override all the in built safety systems, and keep doing things they aren't designed to do, you can break anything.
There are one or two technical inaccuracies in the site, but I guess there may have been something lost in the translation. That's not a criticism - the message is not effected, and I know I couldn't get close to explaining nuclear physics in any foreign language.
