Uranium is mostly just for fission though. Assuming the availability of fusion, probably a reasonable assumption given interstellar travel, I'm not sure you really need uranium very much.

You can use it to make plutonium for bomb pits. So far the only viable fusion devices are H-bombs triggered by such pits.
