Space stations don't need to be round to have artificial gravity. The tethered spacecraft in the diagram to the right represents an alternative design. Put the astronauts in a passenger capsule. (Put the "spam in a can" as they say.) Tether it to a heavy counterweight 16 km away and spin the whole thing around once every three minutes. Place your docking port and nuclear power plant on the axis and you're all set.
How far away should the passenger capsule be placed from the axis of rotation so that it experiences an apparent gravity equal to normal earth gravity?
What is the apparent gravity at the counterweight?
What is the apparent gravity at the nuclear power plant?
