Breeder reactors are really nice in that they produce lots of energy that you can use to produce food and oxygen. Biosphere 2 was a hippy project that tried to reproduce a complex ecosystem that nobody really understood. The Russians had much more pragmatic approaches. For this project https://en.wikipedia.org/wiki/BIOS-3 it's much easier to see how it could scale up to true self-containment.
