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.
