That's the question in Florida, and the topic of a new post from We Support Lee.
Ohio faces a decision soon about its two nuclear reactors, Davis-Besse and Perry, and on Wednesday, neighbors of one of those plants issued a cry for help. The reactors’ problem is that the price of electricity they sell on the high-voltage grid is depressed, mostly because of a surplus of natural gas. And the reactors do not get any revenue for the other benefits they provide. Some of those benefits are regional – emissions-free electricity, reliability with months of fuel on-site, and diversity in case of problems or price spikes with gas or coal, state and federal payroll taxes, and national economic stimulus as the plants buy fuel, supplies and services. Some of the benefits are highly localized, including employment and property taxes. One locality is already feeling the pinch: Oak Harbor on Lake Erie, home to Davis-Besse. The town has a middle school in a building that is 106 years old, and an elementary school from the 1950s, and on May 2 was scheduled to have a referendu

Ultimately the argument about renewability boils down to timescale. Sources like fossil, nuclear, even geothermal, will deplete (with current technology) on human timescales (100s to perhaps 1000s of years). Sources like tidal, solar, wind, etc. will not deplete for millions/billions of years.
The big plus for nuclear verus a lot of other low-carbon sources is that it's practical for baseload today, without needing to pre-suppose breakthroughs that might not appear. IMO it's best not to speculate on breakthroughs (such as extraction of fuel from diffuse sources), otherwise you're just debating energy fantasies with people pushing impractical energy non-solutions. Breeder technology is probably as far as I'd go in terms of projection - it's been practical for decades, but hasn't been successfully commercialised. Breeding plutonium (and U233 from thorium) would take us out 1000s of years - while not renewable, I'd call it sustainable.
That should work well with the recent reprocessing plant proposal--it would be a lot easier if they didn't have to separate actinides at all.
Here is my definition of renewable: the EROEI (energy return on energy invested) is infinite. Now this is precisely what advocates of diffuse power would have you believe about their pet projects. It's not true of course, as it would violate the second law. I'd even settle for something with an EROEI >> 100 as renewable, seeing as infinity is not about to happen.
