> Look at France.

You mean the nation that in 15 years decaronized most of the grid? Yeah how horrible to have 40 years of clean power.

The reason France has problems and has to import, is because since the early 1990s France has stopped building new nuclear reactors.

Even worse, since then leftist governments, specially after 2014 when they basically wanted to copy Germany and get ride of all nuclear. They essentially stopped with vital maintenance.

Unfortunately, they built so many plants in the same period, and those are getting in to their mid years and need maintenance. Because they have largely stopped building new plants, some of the knowlage is now lacking.

Overall, the issue in France is not enough nuclear, not nuclear itself.

France even had really awesome advanced nuclear projects, that were all killed off often by Green/Left governments.

Don't you think its kind of funny to point at the only large industrial nation with a green grid and say 'look at the issues those people have'. If I was German I wish we had those kinds of problems.

> And no, building new powerplants is not the solution. None of these plants were constructed on time or within the budget. They need room, they need to be connected, they need trained workers, they need massive oversight (because the owners will do just enough around security to fulfill the letters of the law, never the spirit of the law).

Actually new plants is the solution. Yes, they need time, that's why building shouldn't have been stopped.

Nuclear plants don't need that much room, and there are already train lines most places, adding a branch line isn't that hard.

Yes, training workers for those jobs is actually good.

Energy is mostly government driven anyway, and so it is in France.

> Nuclear reactors are also not fit for the coming climate change, especially not the ones now being turned off. Almost all of them needed to be shut down in the last summers, because the water intake from rivers was either to warm or there was simply not enough water available.

Saying all of them need to shut down because of water is just wrong. Most nuclear reactors continued to operate in most places in Europe.

The hardest energy problems are in winter, all you need to make sure is that you build new plants in places where you can cool them even under worst case assumptions for future climate and it will be fine.

> In addition, nuclear is only viable, because it gets supported by tax money. Nobody will ensure these things against accidents, the companies are not responsible for transport/storage of the waste and get price guarantees. '

In the European context saying only because tax money is nonsense. The 'markets' are so strongly regulated and often lots of it is state owned. Wind and Solar were only made viable by tax money. Massive government projects to push these drove the economics of scale.

The same could have been done for nuclear for the same price. Had Europe built 100 new nuclear reactors in the last 30 years, the economics of nuclear would be way better. Had Europe not invested massively in wind and solar, the economics there wouldn't be as good.

Even going back to 1970, Jimmy Carter killed nuclear project and focused research on solar. And many of the same trends were happening in Europe. If you prioritize one group of technologies and demonize another you can't then act supersized decades later with the results you get.

And even those project just use the grid as balance, if base load and intermittency were correctly priced, a lot of those economics aren't as good. But governments didn't want to do that, because they wanted more solar/wind even at the cost of later dealing with intermittency.

> And despite all of that, the price for nuclear power rises - while the prices for all others forms of energy drop. From a market standpoint, it makes no sense to invest billions (face it, it will be billions, even if companies responsible tell you it will "only be millions") into a technology that is more expensive than others, harder to control, and not flexible enough. (https://en.wikipedia.org/wiki/Economics_of_nuclear_power_pla...) Investing these billions into decentralization of the power grid and renewable energies (Wind, Solar, Hydro, Storage capacities) will yield a way better return with less complications and more stability.

The economics are not nearly as clear as you make it out to be.

If you build large nuclear project with many of the same reactors multiple times it look pretty good. It also requires far less investment in terms of updating the grid, because usually you can just locate reactors where coal plants were before.

Nuclear build cost are dominated by learning cost, if you build many then they get massively cheaper and you can built them far faster. Look at France in the 70/80s as a good example.

You also solve the intermittency issue because nuclear don't have that. So had we just invested in nuclear, rather then wind and solar, we wouldn't have to do all those investments into intermittency mitigation a problem that still remains unsolved.

Even worse, because intermittency was not price correctly, the base load had to suffer and that made their economics worse. Often nuclear also didn't receive the same subsidies as solar and wind. There are many examples of that.

And this is before we even talk about GenIV reactors. Because all research and development was stopped and often made borderline impossible, we have not progressed. Newer reactor designs have massive amount of potential to be cheaper. They can also solve problem such as heat production for industrial heat. But over the last 30 years there was comically little investment in that.

So what you see as 'economics' and 'market' I see as governments 30 years ago deciding that solar/wind were the future and simply going with it. Had the EU fixed on a single reactor design, even Gen3 design, and had said we will de-carbonize by nuclear it would have been far cheaper and we would be further along by now.

In fact, such a standard nuclear plant would have been an amazing thing to export to other nations as well.

And then have a GenIV reactor in the pipeline after that.

Nuclear isn't the future because 'we' didn't want it to be the future. But it could have been, and it would have been far better future then what we have now.

P.S: Let me give you an example. France had the GenIV Superphénix. They had finally worked out all the issues (including somebody shooting an RPG at it) and could have started to seriously think about building then in larger numbers but by that point they had little interest in building new reactors and the left/green govenrment wanted to kill as soon as possible.

https://en.wikipedia.org/wiki/Superph%C3%A9nix

Had France simply started building 5-10 of a next generation of these in the 2000s they would now be a net energy exporter with reactor that had super low fuel cost (because of breeder) and the per plant cost would likely be a fraction of the PWR designs they are currently planning.

You can see how small this reactor is compared to PWRs. So the overall cost when in production at scale would be amazing.
