I don't think handwaving away the long term storage of nuclear waste and the risk of contaminating large areas can just be ignored, especially with a new unproven reactor design.
Long term storage is solved from a technical perspective, it's a political problem at this point. Deep holes in geologically stable places are ideally fit for purpose, and most of the really nasty stuff isn't' danger after about 200 years.
The Fukushima disaster is expected to kill precisely no one from the surrounding area due to radiation exposure, and the highest exposure among 36,478 dosimeters in Fukushima city in 2011 was 2.7 millisieverts with an average of 0.26 millisieverts. The 2.7 millisievert is believed to have come from a badge left in luggage that was x-rayed. A dose of 0.26 millisieverts is the same as the exposure from to round trip flights between NYC and London.
