You don't know what you're talking about. Sweden, The Netherlands, The Czech Republic all have nuclear power and do not use it for weapons development in any way. I'd bet most nuclear energy producing states don't use their energy plants to develop weapons. How much nuclear waste has been blown up through weapons? A nearly immeasurably small amount no doubt. This is a silly claim all around.
Nuclear power makes as much economic sense as we want it to. We want power we build nuclear plants and send power to homes. We pay for it out of the public coffers. Why should it be profitable any more than schools or parks? We can safely store the waste but not under the current unequal system that demands both profitability from the operation and places a lower value on some human lives than on others with regards to waste disposal. Address these issues and there is nothing unsafe or unsustainable about nuclear power.
