Generally speaking, a fast gas-cooled reactor
Out of the ones that actually exist?
none.
Out of the ones that might possibly one day get made?
USNC's Pylon
10 ton, 300kWe (for reference, 300kW is like a big truck engine)
realistically the only option, given the fact terrestrial SMRs that are in development generally start at 50 tons (most are way >150t) and to remind you, that's without the extra mass for additional radiators necessary for operation in space that you'd have to bolt on
there's also Rolls Royce's pitch for space reactor, but they are really nebulous about the specs and it seems to be just 3d render grift more than anything else

kilopower is too anaemic and SLS level of overpriced
