This is a difficult question because if you build 1 plant, it clearly isn't. But there are large learning effect. Any nation that builds many plants, shares workforce and management rapidly drops cost. If you look at UAE building South Korean plants, they were finishing plants pretty rapidly and if they had simply continued, they could have turned 100% green in just a few more years at quite a low cost overall. It also depends on your energy market and financing. If you have a lot of solar, that simply destroys the market during certain periods, nuclear isn't gone be that profitable. But if you don't have a bunch of wind/solar and you actually value stable energy production. Then its much more reasonable. A nuclear plant can run for 80+ years. So it depends on interest rates you use.
