But this way strikes me as adding unnecessary losses.The trick would be to make sure the exhaust was not too radioactive.

Pumps etc powered by the reactor itself.I have toyed with the idea of a mixed power aircraft. Mainly because then I could have a reactor jettison hatch on the underside marked with yellow and black stripes (La Forge, prepare to dump the core...).However, would a bit of radioactive exhaust at ones airfield be considered an issue? Just tow the aircraft out to the boundary (the time taken could be used to get the reactor warmed up) and have them take off back towards the buildings.
