• It is necessary for the rocket to have a propulsion system based on nuclear power.

• It is not necessary that the nuclear propulsion system works. If a rocket with nuclear propulsion (like the DRACO demonstrator) reaches space but the nuclear propulsion system fails, that would still count as YES.
