It's not that simple. Nuclear regulation in the US has turned (similar to the FDA) into an innovation stifling behemoth... It's a lobbying place and a capital sink and has little to do with safety. If it was about safety, they would shut down current reactor designs yesterday and had started working on Thorium alternatives 20 years ago. The youtube link I posted from TEAC7 conference does explain that quite well.
