This is something similar to our Gas-Cooled Nuclear Reactor/Rocket Engines.

Ours are larger, with room for more than a hundred passengers, and they serve as the rocket motors for the combination Thrust Ring, Castle and Habitats A and B construct.

There are more than six hundred of them, and each has two reactors.

We will only use two hundred to bring the Flying Castle down to Mars. The others will be retained with the other structures.
