your option of coolant without loss implies radiative cooling, how large a surface would be needed for how large a rocket for radiative cooling in the off shut down state? would the sunny side need to be reflective while the dark side needs to be emissive?
- marcosdumay 7y agoNuclear reactors can stand quite high temperatures, so it will be much easier than you would assume if you looked at other rocket projects. Remember that radiating power increases with the 4rth power of the temperature. Also, a shut down reactor quickly gets to ~1% of the energy of an active one, so, again, it's easier than it seems. Generated energy goes down exponentially with time. Of all the problems of creating a nuclear rocket, I don't think cooling stands up.
