Oh, many spacecraft have them, either Plutonium-238 radio-thermal generators or actual operating fission reactors.

Canada was very upset in the late 1970s when a soviet reactor powered satellite ejected its spent reactor and it landed intact and very radioactive in Canada's tundra. It was not supposed to return to earth at all, the satellite was supposed to boost itself into a high orbit before ejecting the reactor, but the booster rocket failed. It was a messy radiological cleanup that Canada tried to get the USSR to pay for.

The US does not use such power sources in orbit, but uses both for long range space probes where solar cells would not work.
