The point of making a profit, is so that you can re-invest and allow private industries into the market.
If I made you a loaf of bread, which took 15 mins, and you could sell it for $2 profit. You would be able to sell more pieces of bread correct?
If another person made you a loaf of bread, which took three days to complete, and you make a loss of $10 with each one sold, how many more pieces of bread are you willing to sell?
One feeds your population, the other has to be bailed out by the government, and everyone loses money and investment and time.
The pro-nuke argument is literally funded by the mining lobby and the fossil fuels industry. Which is why most of their resources are from lobby groups, YouTube videos, public books, and TED talks... Because they know it's going to be ineffective, and they only need to convince the public. Much like how the whole hydrogen-powered cars narrative is going, or environmentally friendly fuels. It's an expensive distraction.
See the RAB that the UK has for the HPC nuke plant build. Companies are allowed to make a profit even before the powerplant is completed. The government will handle insurance, and decommissioning. Which, happens over a century, at taxpayers expense, and it produces no energy. There's also the storage of radioactive material. All of this, uses money and resources that could otherwise be used for constructing renewables (and the fossil fuels industry loves this plan, because every moneypit nuke plant that is constructed, less renewables are built, and fossils gets to remain in the game because they then become only just one of the underperformers, rather than all), decarbonising the grid (faster, see study), and on top of that, everybody makes money.
But don't worry, renewables are also cheaper and more profitable than fossils in most applications as well, so they'll lose out on future energy projects, besides, like in Germany's case, being used as a backup.
