I know that this is a joke, but reactors cannot scale down that far. Unlike an electrical source powered by radioactive decay (like certain pacemakers [1]), the minimum mass for a nuclear reactor includes several kilograms of material. It's possible to shed neutron moderator mass by using high-purity fuel operating on fast fission, but these require more fuel to go critical so they still have multi-kilogram masses.

That may actually be not that far away: >first nuclear battery can deliver 100 microwatts of power and a voltage of 3V >plans to produce a battery with 1 watt of power by 2025 https://www.independent.co.uk/tech/nuclear-battery-betavolt-... | ||
