Yes nuclear power plants are very expensive. But the energy density is phenomenal.
Energetic armortisation is far quicker on a nuclear plant than on solar panels.
And the argument of subsidies is usually a fake one, since governments also pour millions into renewable energies.
Broken down to lifetime cost to the cost of comparable technologies, nuclear is still on the same level as solar and wind.
Since I am from Germany, and German sources might not be ideal to share, let me explain it this way: People are not stupid. They will never choose the financially unwise option, if the other one would seriously be the better one.
This is a German source that incorporates many studies and presents their results. Some agree with my statement, some with yours. But fact is, that the financial difference is very small.

Page 23 for example suggests my statement.
On page 32 you can see the development that suggests that you are right.
But considering the costs for the expansion of the energy grid, battery storage systems, and the rising production costs of everything, I believe Nuclear to be the cheaper option and the far more reliable one.
