Usually it's renewables that's sold over the border rather than nuclear energy. Also, nuclear and batteries, for example, are not comparable. Batteries have an ROI of less than three years. It'll be profitable long before nuclear is even constructed. That's presuming private companies are interested in them. Are you aware of a single nuclear power plant, anywhere in the world, that is unsubsidised? Or even an insurance company that's willing to insure a plant in full? Usually not, usually it's subsidised by the government, with guarantees of profitability to private companies, and at least partially insured and decommissioned by the government. Because nobody wants anything to do with nuclear. Not even nuclear companies. EDF's renewables part of the company, is subsidising the nuclear side. On top of all this, studies are clear on what is faster and more effective at reducing emissions.

Renewables are sold over the border more because they are naturally geographically distributed. I want to see nuclear on the grid as a power source of last resort, so we can destroy the fossil fuel infrastructure, yet keep civilization running if a volcano blocks out the sun or climate change turns the deserts cloudy, or who knows what the future holds.

Fossil fuels are incredibly subsidized, both explicitly and through unpriced externalities. If we must subsidize the alternative, then so be it. Nuclear should get cheaper as we build more.

Most nuclear plants today will melt down if left unattended. That's pretty stupid. We should let engineers make them orders of magnitude safer, with passive air cooling or huge water reserves, so they can be insured at reasonable cost. There is no shortage of ideas on that front.
