Nuclear has never been particularly affordable. It's always been more expensive than coal or gas, even in France in the 70s-80s and China in the 2010s.
Here's how much it cost to build nuclear in France during its golden age: https://ifp.org/nuclear-power-plant-construction-costs. Adjust for inflation and draw your own conclusion.
China's nuclear costs are more opaque, but are estimated at $3B per GW. Again, not competitive.
Ontario produces a majority of its electric power from nuclear (https://en.wikipedia.org/wiki/Nuclear_power_in_Canada) and manages to sell it at competitive rates (https://www.oeb.ca/consumer-information-and-protection/elect...) similar to those in Alberta (https://ucahelps.alberta.ca/your-utilities/rates/historic-ra...) where electricity comes mainly from natural gas after a recent transition from mostly coal. A 2021 report cited at https://www.cns-snc.ca/learn-nuclear/basics-of-nuclear/how-m... finds that nuclear power in Ontario was more cost effective than everything else except hydroelectric power (granted, solar has become much cheaper in just the last few years). And this is in spite of multiple reactor shutdowns.
Yes, running a nuclear power plant is pretty cheap, if you ignore the cost of building and decommissioning it.
