The problems stemming from tsunami damage to Fukushima Dachii reactor plant appear to be nonstop and growing regularly, and also consuming immense amounts of water while global droughts are becoming pandemic. Although one hopes they use undrinkable saltwater to cool all that nuclear fuel, I suspect they may not. Regardless, the water is undeniably unusable in ANY form once applied to spent or melting fuel rods. For many, many generations . Aside from the morality of generating material that is still going to be radioactive so many generations in the future I don't even want to do the math, we do not have the knowledge, capability, or apparently even the incentive to properly solve nuclear mishaps on this scale. All of which means, to a sane and responsible person, we should not be utilizing this technology.
SHUT THEM ALL DOWN NOW.
