It depends on the cost, honestly. If the cost is too high, no utility will continue to run those plants. I agree with you, but the reality is that finance runs everything these days.

Main cost of nuclear power plant is the capital cost of building it. Operating nuclear plant is extremely cheap, even cheaper than maintaining solar or wind power plants.

Yea, and capex is the hardest nut to crack since it requires investors that want to make a profit sooner rather than later. I love nuclear, but it's not a realistic resource at this time. All the downvotes in the world won't make this untrue.
