A bit of a stretch maybe, but I'm considering us to be discussing whether an energy source is renewable on Earth. The Sun is not renewable, but by the time that it's no longer viable the Earth will be long gone as well! So as long as the Earth exists, I would say that solar PV and other solar driven processes like wind and hydro are renewable.

By these standards yes, deep geothermal and tidal are "not renewable" either.

But that's exactly the "problem", there's enough fertile material for potential millions of years of consumption, and that's for fission alone.

I think the debacle is more because the definition of "renewable" is a little arbitrary than the dilemma if nuclear is renewable or not

I think we both agree on fertile material as discussed in another comment, the longevity issue is mostly with conventional LWRs burning up our fuel rapidly.

I'm just being pedantic about the sun, lol

Well, yes, the obvious counter argument being that, you will never build more advanced reactors on scale (some are already available), or develop new fuel cycle if you stunt the evolution process and block the technology we already have.

Imagine saying to be favourable to installing solar panels but only when they will be 100% recyclable and with efficiency close to the theorical maximum
