Smoked Out: Mystery smoke spews from North Korea nuke plant crippled by typhoons sparking fears of Fukushima-style disaster

Mr Plant said: "The real risk is if they were in the middle of operations and there was a huge flood and it knocked out the pumps like it did in Fukushima." He added: “If for some crazy reason they tried to operate under conditions where the cooling wasn’t working, then all the bad things would happen. “And there are residual safety concerns about the reactors. The old one is very old and even well regulated reactors of that vintage do not meet modern safety standards.”
