Nuclear seems like the best hope for humanity, really a shame people are so afraid of it. Although, I guess the fear is justified given how many disasters there have been.
But fearmongering and people being incapable of understanding just how harmful coal is even in comparison to the worst nuclear disasters (which people frequently overestimate the harm from) has lead to significant regulations and cuts in funding, to the point where you're arguing about tech from the 70s.
There's tons of promising research, and without all of the fear, we would not be talking about uranium based BWR. We would have entire other classes of fuel, and some of the Gen4 designs that have been researched could burn all actinides.
You can create nuclear power from a lot more than just uranium.
