There is a pretty good little nuclear power museum in Arco Idaho. Arco was the first town powered by nuclear although just for an hour or so in 1955. The museum had radiation detectors and radioactive sources you could learn about distance and shielding. That along with time are the 3 factors that can make radiation safe. They even had a air force prototype power plant sitting in the parking lot that was to see if a flying nuclear reactor would be possible. Spoiler alert, it didn't seem feasible at least in the 60s.
Also near Arco is Craters of the Moon national monument. The real reason we went there. Very cool landscape of lava flows and tubes from the Yellowstone supervolcano. Even when it's 110 degrees out in August the lava tube caves still have ice floors because of the amazing insulation of volcanic rock.
Now there's a power source to tap, a supervolcano. And if we could drain the energy off so it never erupted again then that's a real humanity saving effort.
