After all, it has all the costs of a coal or natural gas (a turbine who takes heated water to generate electricity), plus all the extra costs associated to the reality that nuclear explosions are more difficult to deal with than coal or natural gas burning.
By the document posted above (which was commissioned by the UK), nuclear has an edge in the CO2 emissions by KWh generated. Each solar panel produces very little in isolation, so the fabrication costs are outsized for its contribution. That said, they are not that far off.
