Well, Germany invested a zillion into a pebble-based thorium high-temperature reactor. Technological marvel. It didn't work reliable enough and was too costly. Closed down by the industry relatively silently... There is a site for nuclear waste. It does not work as expected. It needs to be cleaned for a few zillions... Nuclear is dead in Germany. Nobody wants it, it's too costly, it lacks critical solutions (like fuel reprocessing and nuclear waste storage), which also nobody wants to host.
