I wanted to check up your reasoning. Actual calculations can be pretty complicated so I relied on a real world example: the largest solar array project under construction in the world, Australia's Sun Cable.

A few numbers: the projected cost is $20 billion. The nameplate capacity is 10GW. The most efficient solar plant in the world (located in Arizona) has an efficiency of about 30%, and I think we can assume similar efficiency for the Australian one, which translates to a 3GW average output, assuming it includes enough giant batteries to stabilize the output. The size of the array, in one of the most favourable places in the world by climatic conditions, is 150Km^2 (more or les the size of Amsterdam). Note that in the Australian desert we can assume the cost of the land to be almost zero.
Always according to WP, the cost of nuclear per GW should be about $6 billion. So a 3GW nuclear power plant should cost about the same as the 3GW (in average output) solar array. The difference is that the power output of a nuclear plant is steady and entirely predictable, it occupies a minimal fraction of the space needed by the solar array, and it can work anywhere in the world- from Australia to the coldest and rainiest regions. Transferring the Sun Cable project from the Australian desert to Germany is simply impossible due to the climate and the cost of land; while it's perfectly possible to build in Germany ten or twenty 3GW nuclear plants.
