Now you know why "nuclear power may have been dangerous in the past, but with modern technology it's completely safe and Chernobyl will never happen again" is not a good argument.
Chernobyl is the perfect example to not use outdated old technology. Had they used the modern western technology at that time to upgrade their nuclear reactors the kill switch would have prevented the whole disaster instead of increasing the neutrons make the core a nuclear bomb.
Next time educate yourself with facts before making a fool out of yourself
But you are aware that this thread is about a reactor in the west, that "updated" their certified hardware to a VM instead running on windows NT?
Wikipedia's pages on Chernobyl say that construction started in 1972 and the problem with the control rods causing an initial spike of power was discovered in 1983 ?
