Not quite compact nuclear reactors but interestingly, we've had the tech for decades to manufacture radioisotope thermoelectric generators powered by various radioisotopes like Strontium and Cerium. They have been known to kick out 1000W with a 10-20 year lifespan. They've been used for electrical power supply in remote areas. And this was 40 years ago.

I can only imagine what they've got in the DUMBs.
