In general I am in favor of the newer Gen 3 and the future Gen 4 designs. Gen 1 and 2 now in the field are fossils. Yes, there is nuclear waste that we don’[t know how to handle yet and are currently burying. But…. I believe the human race will eventually skip over fission and go to fusion that, like the sun, will convert hydrogen to helium and produce tremendous quantities of energy. The temperatures are incredibly high so containment is still in the distant future. But, I have faith our children’s children will figure it out. In 100 years, there will be fusion facilities operating and converting the nuclear waste made today into other elements that will be used to manufacture who know what. I cannot guess. They will look back at our technology today and think it quaint – the way we look back at horse and buggy days and think of all the manure dropped by the horse and how it polluted the water in cities. One thing is certain. It we stop funding these types of projects we will never become the utopian “Hydrogen society” and nuclear waste will continue to fester for tens of thousands of years.
