"The best case for nuclear in the future" will be off Earth (I hope). High density portable energy sources are a godsend for solar system colonization. Solar and wind on Mars are much worse energy sources than on Earth, especially if you factor in the cost of transport. For a long time the most powerful system per kg is the one to use.

Launching them from the ground is a bit risky though. We can do it reasonably safely with RTGs but with complete nuclear reactors the risk of contamination in a crash is somewhat greater.

Where did you get that information? A reactor that has never been run has almost no radioactivity. Its basically just native uranium metal/oxide. RTGs are a higher risk and more radioactive. It is really a shame that such wrong ideas are so widespread.
