Firstly, you talk about $ per capacity in MW, however solar capacity factor is 20%. Only use a levelized cost per MWh.
Secondly, solar needs storage which you think is trivial, but which turns out to be wayyyy more expensive than the solar panels. Some reports[1] only compare short-term (peaker generation) for storage. Nuclear is expensive, but battery storage is far more expensive to cover daily or longer load variation (non-peaker). That report mentions in a footnote a levelized cost of storage of crazy high $1613/MWh to $3034/MWh.
I strongly disagree with your point “we can install twice the capacity in MW for solar and still have money left over to put into a smarter grid or storage” because you appear to be making up numbers - what is your reference to sources?
You used MW in that comment - your new comment is not clarifying whether you made a mistake or what your actual point is.
LCOE is an averaged cost/MWh, which is absolutely inappropriate to use when discussing whether nuclear is expensive or not, because LCOE ignores usage patterns (which you obviously know, but are hand-waving away as “money left over”). From your Wikipedia link: “One of the most important potential limitations of LCOE is that it may not control for time effects associated with matching electricity production to demand” and “To ensure enough electricity is always available to meet demand, storage or backup generation may be required, which adds costs that are not included in the LCOE”.
Finally, almost any plot that uses “installed capacity” is deceptive by design: because capacity factors make solar/wind appear 5x better, which is not a trivial difference on a graph. Instantaneous capacity is usually not relevant (except during “peaker” loads).
