That's the question in Florida, and the topic of a new post from We Support Lee.
Below is from our rapid response team . Yesterday, regional anti-nuclear organizations asked federal nuclear energy regulators to launch an investigation into what it claims are “newly identified flaws” in Westinghouse’s advanced reactor design, the AP1000. During a teleconference releasing a report on the subject, participants urged the Nuclear Regulatory Commission to suspend license reviews of proposed AP1000 reactors. In its news release, even the groups making these allegations provide conflicting information on its findings. In one instance, the groups cite “dozens of corrosion holes” at reactor vessels and in another says that eight holes have been documented. In all cases, there is another containment mechanism that would provide a barrier to radiation release. Below, we examine why these claims are unwarranted and why the AP1000 design certification process should continue as designated by the NRC. Myth: In the AP1000 reactor design, the gap between the shield bu...

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.
