The World Nuclear numbers use mined natural uranium on the input side, so enrichment losses are implicitly included for nuclear. There are a lot of different PV degradation mechanisms. Most of them have known engineering solutions. I personally think that some modules installed today will have an operational lifetime in excess of 50 years, but I'm conservative when it comes to picking defensible numbers for extrapolation. Did you account for cell-to-module energy losses and inverter loading ratios > 1 when you made your estimates? I chose 20% capacity factor, despite published national (US) EIA numbers in excess of 25% for utility scale projects, because EIA reports AC (post-inverter) numbers. With typical utility scale inverter loading ratios now at 1.3 or so, the module-level capacity factor is more like 20%. None of these issues change your major conclusions. I'm just going into details because I rarely find anyone else interested in the subject matter.
