I wouldn't consider Fukishima modern either, it began construction in 1967, with the actual design plans being a bit older. That is like 25 years from the first

I wouldn't consider Fukishima modern either, it began construction in 1967, with the actual design plans being a bit older. That is like 25 years from the first nuclear reactors, we are now 50 years of research and technology beyond fukishima. Yeah it has had some upgrades, but you can only modify an already existent reactor design so much.
