> It can be effectively renewable for all practical purposes, but there's an aversion to breeder reactors.

Breeder reactors reduce long-term waste issues, but they don't make nuclear renewable.

They push the timeline out so far that it's effectively renewable. The sun will burn out at some point, too, but we don't say solar is non-renewable.

We don't say solar is non-renewable because using every single available bit of solar today has no impact on the solar energy available tomorrow. This is not true of nuclear, even if you increase the total quantity of available fission-derived energy by 50 or 100 or whatever the outer estimate is for breeder reactors compared to non-breeder fission.

		Based on the math in this paper[1] there's enough uranium floating around to keep the planet running on the order of hundreds of millions of years at modern energy consumption levels. The price of the material would go up compared to what it costs currently, but the raw material costs are a small fraction of bottom line anyway.
