Back in the 60's, people thought everything would be nuclear-powered; atomic cars, planes, trains, houses, etc. But like with building-sized computers, we've chosen a different path through the tech tree. There were terrestrial exceptions though, like "the Beta-M is a radioisotope thermoelectric generator (RTG) that was used in Soviet-era lighthouses and beacons." https://en.wikipedia.org/wiki/Beta-M https://en.wikipedia.org/wiki/Beta-M But people happened across them and got radiation poisoning, so imagine that happening a lot more often if they were powering all manner of home appliance. Also a lot more dirty bombs.
