What is renewable about nuclear? It's not a fossil fuel, but uranium has to be mined and is a finite resource just like oil.

    Uranium isn't the only fuel source, for one. Fusion reactors, if we can figure out the underlying science, world likely use hydrogen. New generation reactors can use Thorium, and breeder tractors are able to generate usable fuel from nuclear waste.

    Not to mention, uranium is finite but we have enough supply of it to develop other technologies while we still reduce emissions via nuclear.

    And this is discounting new technologies which could allow us to create a large artificial uranium supply.

    It's not renewable but we have something like 200 years worth. It's a cleaner stopgap than fossil fuels until we figure out fusion and build up renewable capacity.

    200 years with current technology.

    With breeders reactors such as superphenix built in the 90s you can multiply this amount by almost a 100.

    After a millennia if we still rely on the same technology and we start to worry about the supply we can start seawater extraction of uranium. Seawater extraction is not considered economically viable right now but it as the potential of bringing the supply nuclear reactors for another few billions years.

    So from a practical point of view it could be considered as renewable or close to it.
