Similarly, the Russian RBMK nuclear reactors were designed for dual purpose: Producing electricity and producing weapons grade plutonium. Following your argument, we should weight down the Chernobyl disaster, when counting statistics for nuclear power?
Can you cite where the Chernobyl disaster was made the worse by the weapons grade plutonium production?
I have never seen that, but of course you would reduce the numbers.
It would be zero, if like some nuclear facilities the electricity was purely a byproduct. Unless I guess something that does the power creates the mess.
