Our oldest tested solar array is now about 40 years old and at age 35 had lost only 3.88% or 0.1% per year performance. Panels mounted in areas with higher UV levels will degrade a bit more but lower than 0.5% per year, more in the 0.2% per year. We could see 80 year old solar arrays still producing 85 to 90% of their original level.
"I don’t for a moment accept your figures are for nuclear power itself."
They aren't my numbers. They are real world numbers and you can check the sources.
The announced strike price for the proposed Hinkley Point reactors has been announced as £0.925. This includes UK provided loan guarantees. When the value of these guarantees are included the price rises to £0.10. $0.16/kWh.
This means that regardless of how cheap other sources of electricity might be the French and Chinese owners of the reactors will be paid 16 cents for the electricity they produce. They are further guaranteed that their electricity will be purchased first meaning that it is likely that cheaper sources will be curtailed.
This is a guaranteed price for all electricity produced for the next 35 years and the price will increase with inflation.

An analysis of the Vogtle reactor costs by Citigroup in early 2014 found the LCOE for electricity from those reactors to cost 11 cents per kWh. That is assuming no further cost or timeline overruns.
They also stated that reactors built after the Vogtle units would likely produce more expensive electricity as they would not be able to receive as low financing rates as Vogtle has.

I'm not going to get into the nuclear safety issue with you.
Nuclear is priced off the table simply because nuclear costs too much to build. Since the price of new nuclear would be well over 11c/kWh in the US (rising as interest rates recover) we could somehow eliminate enough of the safety measures to bring the cost of new nuclear down to 8c/kWh and it still would not be competitive.
Furthermore, load-following increases the kWh cost of nuclear. The price of nuclear is determined by the amount of power produced by the capex, finex and opex costs.
Producing less makes the Cost/Produced number larger.
