From what I have read, the best traditional fission plant designs are very safe, efficient, and produce few byproducts. It's the older plants that have problems but we have learned from them and made improvements. Compared to the most state-of-the-art plant, thorium reactors are not significantly better and we have years of first-hand experience with traditional uranium reactors and very little with liquid fluoride thorium reactors so the incentives to start at square 1 with an new technology are small. So the good news is if we ever got over our irrational fear of nuclear power, we have time-tested plans for safe, clean and efficient power plants ready to be built.
