You would think the cooling would be a critical issue (It usually is in
spacecraft), but the Russians flew a few surveillance birds with
reactors on board (and had at least one more such fail to make orbit).
Cosmos 954 also failed to eject its core to a safe orbit before reentry
and radioactive components were recovered from the impact site in
So yes, a nuclear powered bird is possible, I suspect by running the
entire thermodynamic cycle very hot and thereby increasing the radiative
cooling efficiency on the 'cold' side.
