Where are the comments about „molten-salt reactors dont need any of that”. And a closed water loop. China builds them on a desert and we cannot build them anywere in Europe due to plain stupidity.

>we cannot build them anywere in Europe due to plain stupidity. Economics I think. Nuclear power has gone bankrupt in France already (arguably more than once) and gotten bailed out. Now they produce electricity at a price that's often above market price, with losses covered by the taxpayers. This despite relying on cheap cooling from rivers. Adding more expensive cooling won't help. We've quite recently reached mass production economies of scale for both solar panels and batteries. The implications are that the price of electricity is set to drop even more in the years to come.

  Solar panels keep getting better and cheaper every year. Can't say the same for nuclear.

    I believe this is why the USA recently declared that it's no longer going to follow the "linear no-threshold model" and "as low as reasonable achievable" principle of radiation exposure. In other words they're declaring that a small amount of radiation is good for you. Building a reactor without shielding and with a single open-cycle water loop should reduce costs, right? (Do you know what else reduces costs? Apparently, putting a foot of graphite at the bottom of your control rods and not paying close attention to a dangerously unstable reactor during an unusual experiment. These aren't official American policy yet.) Also, the USA's recent ban on solar electricity equipment should help make other forms more competitive.

      The harms of radiation are massively overhyped. Nobody from the Fukushima accident died from radiation sickness or radiation syndrome, and so far there's been no evidence of long term elevated cancer rates either. Meanwhile the nuclear industry has been drowning for 50+ years from egregious layers of overregulation. It costed NuScale $500+ Million just to write the documents required for regulatory approval for a new reactor design. Microsoft is spending $60 Million a year to build an LLM whose only purpose is to automate writing nuclear regulatory documents. I don't support the Trump admin one iota, but I'm also saddened that democrats tend to be too safetyist to do an honest cost benefit evaluation of some of these insane regulations.

        >The harms of radiation are massively overhyped. >Nobody from the Fukushima accident died from radiation sickness or radiation syndrome, and so far there's been no evidence of long term elevated cancer rates either. You say these two things as if the second statement supports the first, but it doesn't. The dangers of radiation are very well known and don't change at all based on what happened at Fukushima. If you fire a gun and miss, the gun is still dangerous. >Meanwhile the nuclear industry has been drowning for 50+ years from egregious layers of overregulation. Here's an account of two gruesome deaths caused by poor regulation of nuclear materials in Japan. It happened 12 years before Fukushima. https://science.howstuffworks.com/hisashi-ouchi.htm https://science.howstuffworks.com/hisashi-ouchi.htm

        Interesting but people die (or are severely injured) in all kinds of industrial accidents all the time. Unfortunately, with or without regulation it comes with the territory of a modern industrial society.

  > Now they produce electricity at a price that's often above market price Do you have any source? I'm not french and all I can hear from the news is that France's nuclear electricity is cheap, for example: https://thenextweb.com/news/france-energy-advantage-ai-data-centres https://thenextweb.com/news/france-energy-advantage-ai-data-... Now I'm curious what the truth is. Are these articles just fake-news trying to ride the AI wave? (not suggesting, just asking)

    At this point in time it can be assumed that 90% of everything on the internet is a lie. French nuclear electricity is cheap because the government subsidizes it to keep it afloat. And because continental European electricity is generally expensive. It probably wouldn't survive in a free market.

      Free market probably means they rely on Russian gas or coal from other countries ? Sometimes it’s worth paying a bit more to be independent

    >Do you have any source? There are many sources and it's of course complicated, but around 6 eurocents per kWh seems to be an accepted semi-official figure. "The full cost of existing nuclear power calculated by the CRE amounts to respectively €60.7/MWh" (https://www.enerdata.net/publications/daily-energy-news/frances-cre-unveils-forecast-nuclear-power-costs-over-period-2026-2040.html https://www.enerdata.net/publications/daily-energy-news/fran...) One can also deduce that it's somewhere between the old ARENH price of 4 cents (which is known to be unsustainable) and the new price of 7 cents. Prices for wholesale electricity in the FR region have dipped below 5 cents (monthly average) several times in recent years. (Source: Nordpool).

  The bad financial shape of EDF had multiple reasons: 1. Cost overruns in construction of the new EPR reactors. The EPR is a extremely safe and as a result extremely overengineered and expensive design. The aim was to merge the French N4 design and German Konvoi design and have a standard design which would satisfy nuclear regulators in all countries. France wants now to simplify EPR and build cheaper and simpler EPR2. 2. EDF was mandated to sell large part of it's electricity production at bellow the market value. The ARENH mechanism. "The ARENH (which in French means “regulated access to historic nuclear energy”) was created in 2011 in the context of the opening of the electricity market to competition. The law that provided a framework for this opening-up had the main objective of enabling all consumers to benefit from the competitiveness of the French nuclear fleet. Before the ARENH, EDF was the main electricity supplier, covering 95% of the French territory (the rest being covered by local distribution companies). Under the ARENH, so-called alternative suppliers (i.e. other than EDF) obtained access to a regulated price (€42/MWh) for the electricity produced by EDF’s historic nuclear fleet within a volume limit of 100 TWh per year. This is equivalent to almost a third (27.64%) of 2024 French nuclear production (361.7 TWh)." https://hayaenergy.com/blog-end-of-french-nuclear-procurement/ https://hayaenergy.com/blog-end-of-french-nuclear-procuremen...
