Chernobyl actual accident profile
Just as a correction to all of you who saw other reactors as being as unsafe as the Chernobyl design and having had similar accidents.
The Chernobyl reactor design has a positive void coefficient. This means that when it loses coolant the nuclear reaction accelerates which is really, really not a good idea. ALL western reactors have a negative void coefficient - if they lose coolant and if you leave it alone it shuts down.
Further, the Chernobyl reactor did not have a melt down, it actually went prompt critical and the explosion in the reactor chamber was a major nuclear release rather than a hydrogen explosion. This was all reported in the atomic energy agency final report but for some reason wasn't considered news and hence did not appear in any of the main stream news media at the time. I suspect that the Internet wouldn't let that happen today.
If anyone is still operating a Chernobyl style reactor they are completely insane and seriously need to stop it right now.
I could make further comment but I really can't be bothered to butt heads with all the ignorant trolls, I'll let the rest of you fight it out as you see fit.
