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.
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.

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’m just being pedantic about the sun, lol
That’s look like not renewable, but like “smaller resources cost”.
