The typical answers from nuclear proponents never cover what to do with the waste product.
Also new reactor types have solved all these problems. They can create very little waste that only has to be stored a far shorter time.
The problem is that anti-nuclear people have created a environment where no more research happens and old technology just limps along.
The science is clear, the needed technology is understood, we just need somebody to build it. There are startups who try, but its very difficult.
