I would've thought they had some sort of fail safe in place for such an occassion. I understand the diesel generators went out, but you would think, they'd have plans A through Z covered. I can only assume once everything goes to shit, there will be a major overhaul of their Nuclear energy program. I think with any exposure, there could be signs of radiation poisoning. It won't be severe like Depleted Uranium, but it'll probably be mild stuff like nausea, vomiting and the shits. The other stuff would probably not happen, but depends on if it magically got 10 fold worse.
