I think nuclear has parallel to mainframes. Capital intensive, long lead time, expensive to operate/maintain/dispose and practically irrelevant in the day of distributed (computing) generation and storage.

It’s uncanny how the narrative rhymes: we have insanely capable portable computing devices at price points that are accessible to every person across the planet. Similarly, distributed generation (and storage) are already bringing electricity to people who have no real chance of being on the grid ever.

I see no way the economics working out for nuclear, except for niche uses.

I can even imagine the grid being something relegated for long range / high intensity applications (instead of household distribution) in a few hundred years

Consider Poland. 80% of its electricity production (as of this moment, almost midnight) is coal + gas (and it imports from Germany). Its generation mix results in 855 grams of CO₂ per kWh.

Consider Germany. 50% is coal + gas, 22% is wind + biomass. At 490 g/kWh.

Italy: 60% gas at 386 g/kWh.

Then compare them to France: 75% of the electricity comes from nuclear, at 47 g/kWh.

All of this despite abundant wind+solar capacity installed in Germany, France, Italy, and Poland.

There is a strong need to remove CO₂-intensive generators and replace them by something that does not send CO₂ into the air.

There is also a strong need to build up capacity to store energy.
