Nuclear has always been expensive af. It's just "cheap" because all the real costs are not carried by the providers, but the states. Try getting an insurance for a nuclear power plant, have to find a solution for the waste. Besides that just take a look at the French: having to shut down mamy of their nuclear power plants, because the rivers don't have enough water to cool them down these days. On the other hand renewables, that are much faster build and way cheaper, are amortized after a few years.
