HOW ABOUT CHEAPER AND CLEANER THORIUM. Thorium is a waste product in almost every granite quarry on earth, it can't be weaponized like other fissile material, a catastrophic meltdown would make an acre of land uninhabitable for about 60 years, a failsafe meltdown would just leave a 70 gallon containment vessel that needs to be disposed of, the technology exists the limitation is corrosion of parts, which china is saying they fixed and we know should be fixed with modern alloys, the chief factor in thorium having been abandoned in the west is that it would be too cheap and the regulatory board has too much competing financial interest in uranium reactors. "Too cheap" means other energy sectors couldn't compete and jobs and GDP would vanish over night. The main reactor can be made small enough to fit in the bed of a pick-up truck and still go under an overpass, thorium reactors would make sense in all maritime vessels over 60 crew, passenger and freight craft of the largest order, make sense as a military technology for rapid establishment of a forward operating base, you could fit a half dozen safely in a typical suburban home and create grid redundancy by eliminating telegraphed and centralized power infrastructure.
