For one thing, the nuclear waste can be reprocessed. The energy currently extracted in a nuclear plant represents roughly 10% of the energy "stored" in nuclear fuel. Reprocessing can help extract a huge additional amount of energy.

Of course, the downside of reprocessing is that it creates plutonium, a substance much more dangerous in the wrong hands. Nevertheless, the added costs of security will be more than justified by the increased usability of nuclear fuel.

As for the limited lifetime of nuclear plants, that is simply not true. With the replacement of a few key components, a nuclear power plant can last indefinitely. Witness the current rash of relicensings, where older nuclear plants are granted 20-year extensions of their originial operating licenses. And even once you decommission a nuclear plant, the space is much less polluted than, say, an old oil-fired plant, so condominiums are actually not out of the question.
