France To Cut Carbon Emissions, Russian Energy Influence With 14 Nuclear Reactors (arstechnica.com) 110

An anonymous reader quotes a report from Ars Technica: France is planning to build up to 14 nuclear reactors in an attempt to shore up the country's aging nuclear fleet while also reducing the country's carbon emissions. And while the first reactors won't open for years, the announcement could serve to undercut Russia's attempts to keep Europe dependent on natural gas. President Emmanuel Macron announced the decision last week, saying that state-backed Electricite de France, also known as EDF, will build six new plants starting in 2028, with the option to build another eight by 2050. EDF estimates that six next-generation pressurized water reactors will cost around $57 billion. The first could be commissioned as early as 2035.

The move is a sharp reversal of Macron's earlier pledge to close several reactors over the next decade or so. National politics almost certainly play a role -- the nuclear power sector in France employs around 220,000 people, according to one estimate. "What our country needs is the rebirth of France's nuclear industry," Macron said at a nuclear turbine factory that EDF had just purchased from GE. "The time has come for a nuclear renaissance," he said. Macron also said that EDF will build a prototype small modular reactor, or SMR, by 2030. SMRs are fission reactors that are designed to be built in a factory and transported to their final destination. They generally produce less than 1 MW of power and are intended to be more economical than traditional reactors, which are constructed on-site. EDF will face stiff competition from numerous companies, from heavyweights like Westinghouse to startups like NuScale and Chinese firms like China Huaneng Group, which are pushing to commercialize SMRs.

France's new plans were announced less than two weeks after the EU announced that nuclear power would be considered "sustainable," a decision that was subject to intense lobbying by the French government. It also comes at a time of heightened tensions with Russia and its president, Vladimir Putin. Russia has flooded the EU with cheap natural gas, leaving the bloc dependent on the country for much of its energy. In 2020, the EU received more than 40 percent of its natural gas from Russia. The Nord Stream 2 pipeline, which could double Russian exports to the region, appears likely to increase the bloc's dependence. Macron's announcement, while possibly coincidental, could signal that France is interested in taking over as Europe's power center.

      Nuclear power has been important to France for decades. This is not the type of commitment that Macron can back out of. While there has recently been some anti-nuclear sentiment in France that swayed Macron the candidate, I think it's clear that once in office he realized it was their best option. Nuclear power has allowed France to have the cleanest energy production of any first world nation. With Germany's retreat from nuclear, France could set themselves up to be the primary power producer in Europe, especially if they export those SMRs. There are good political, economical, and environmental reasons for France to do this and Macron is a pragmatist.

      What are you basing your statement on?

        Yep. Germany is importing more and more electricity from France as they shut down their nuclear program. These power stations swill supply that demand in the future.

          France should build the nuclear plants right on the French/German border. So Germany has to pay for French power while at the same time suffering all the consequences of a melt down for a reactor that isn't theirs. That's called not having your cake and not eating it too.

          • I'm sure the risk of a melt-down is baked into whatever price Germany is paying for the power.

              Your point that it was detected far away stands, but I'm pretty sure the first ones to know were in Chernobyl. Years ago, I read an interesting interview with one of the operators that survived. He posted guard outside the reactor building while his soon to be deceased colleagues investigated the anomaly. He still spent months in the hospital.

                  The quote directly contradicts your implied claim that Germany has to import power because of lack of nuclear power. Looking at the data of the last seven years, Germany always exported more power to France than vice versa . The idea that Germany depends on power imports from France is simply false.

          It is getting boring to always respond to this nonsense with data: Since the beginning of 2022, Germany exported 3.2 TWh to France and imported 0.3 TWh from France.

          In the past, nuclear proponents on slashdot sometimes had good arguments (okay, they were always clowns like the one who insisted that radiation is actually good for you), but today's endless repetition of easily debunked nonsense just starts to get annoying.

So the project is about paying other countries for something he could have by paying french workers. This shows that he never had a shirt, middle and long term vision, just randomly follies polls.

      • What are you basing your statement on?

        Probably simply irrational dislike of nuclear energy.

        Nuclear fission energy is a debate where few keep a level head that is drowned in the stench of tribalism. There is also a smal party in the Netherlands that wants to build more nuclear reactors, clearly only because “the leftists” hate it. On it's website, nothing is mentioned for instance on that it's not a fossil fuel and they don't seem to give a compelling reason either.

      Nuclear power contributes more than 70% of France's needs. It just so happens that France is due to decommission 14 of its 50+ nuclear reactors & it's now announcing it's going to build 14 more. Unless France formerly intended to shift away from nuclear energy to something else, & taking into consideration the timescales involved (20-30 years), this looks a lot like business as usual & nothing to do with Russian gas or the Ukraine/NATO situation.
      • by Anonymous Coward

        Newer reactors are generally pushing out more power relative to older reactors built on roughly the same site footprint.

        So it's possible to retire 14 reactors, build 14 reactors, and still help the rest of Europe transition away from Russian gas with increased energy exports.

      • Supposedly French electricity needs are 70%+ met with nuclear power. But the goal of moving towards zero emissions will mean that there should be a growth of electricity needs whilst ramping down carbon based energy. So there must be an increase of total power output. Not to say that's not possible with the same number of plants, but there should be more than power replacements. Indeed, regardless of Russian gas etcetera.

          France has a long maritime coastline. If push comes to shove, it has access to as much uranium as it wants or needs.

          True, seawater extraction will never be the preferred option while cheaper methods are available, but it's very reassuring to have this available as a backstop.

        • How much access to Uranium and other fissionable materials does France have?

          With access to the sea there's an effectively limitless supply of uranium, there's uranium salts in the sea and more produced all the time through erosion.

          Thorium is as common in the Earth's crust as lead, we are not going to run out.

      But it does have an effect. Russia can now only afford to lean so hard knowing that France's need for their gas has an expiration date. Lean too hard and there ios nasty blowback coming .

      • France does not import much gas from Russia ....

        No idea where that stupid /. "Russia gas dependency" meme is coming from.

        The world is completely dependent on petrol from Arabia and around - seems no one cares about that.

        • Probably from the big ass pipeline being built to send Russian gas to Germany?

          • Yes, and?

            What has the pipeline to do with France? Not much. Why would France be depending on it? Why would Germany? A pipeline is a pipeline. Do you really think anyone in Europe is making himself dependent on Russia? You are delusional.

            • So I'm delusional because Russian gas flowing through a pipeline to Germany doesn't make Germany dependent on Russian gas? And everyone knows every molecule of gas going through that pipeline stays in Germany (who isn't dependent on it and could care less about it according to you), and absolutely doesn't get distributed to the rest of Europe in any way. And certainly not France, who shares a border with Germany!

              If Europe doesn't need it, why was it built? Was it a thousand kilometers of make-work for pi

                Exactly.

                the amount of gas going through the pipeline per year is roughly 20 - 100 times the amount of gas Germany uses per year. Are you really that dumb?

                and absolutely doesn't get distributed to the rest of Europe in any way. And

          I guess you missed the whole electric car thing then?

          Actually, the U.S. is a net exporter of petroleum, but we don't hear a lot about that because it blows up the whole narrative of "having" to raise prices at the pump whenever someone farts in the desert.

  • less than 1GW not less than 1MW. I believe the technical definition of SMR is 1GW thermal which translates into around 300MW juice. If France planned on building 28 1MW plants that gets a whole 28MW of power. Not even a dent in the total power needed by France.
    • Power plant speccs are given in MWh/GWh electricity.

      If you want to know thermal, you either know the formula how to calculate it (hint, just roughly double it and add 10%) or it is given in a site note.

        PWRs and BWRs are typically about 35% efficient - a reactor producing 1GW of electricity gross will be producing about 3GW of heat. They actually operate at quite a low temperature, relatively speaking (about 350 deg C) compared to a gas turbine generator burning natural gas (ca. 2000 deg C) hence the low efficiency figure.

        There are more efficient power reactors in use today, like the British AGRs which use CO2 for cooling and heat transfer. They manage about 40% efficiency, operating at over 400 deg C. Som

  • Energy self sufficiency reduces the chances of political bullying. ie Germany

    • France is already self sufficient except for O&G. The electricity that they import is doing a favor for Germany. Basically, France with nuclear and Poland with Coal, enable Germany to live on their expensive wind/solar.
  • Build them all along the German border. That will keep them out for sure.
  • The only way to make SMRs more profitable than full-sized reactors is to skimp on safety and security. Per-unit costs necessary to make reactors as safe as possible (like inspections) cost much the same amount no matter the size of the reactor. Increasing the number of installations means increasing the number of installations which must be secured. SMRs have been tried several times and never actually even worked right, but even if you solved that problem they still wouldn't make sense. Constructing them a

  • I wonder if the 1MW quoted in the article for the SMR's is correct? For a comparison of scale, until recently I took care of the power system at a medium sized paper mill. Our typical electrical load was about 70MW. We had a co-generation facility, whee a single boiler fed steam to a geneartor with a nameplate rating of 105MW. 1MW is, in reality, not much power.
    • by nojayuk ( 567177 )

      The 1MW comment about SMRs is probably a typo for 1GW since most real reactors being built these days are designed to produce 1GW-plus of electrical power, although there are one or two builds that only will produce 300MW or 450MW when complete.

      Small Modular Reactor designs are typically sub-100MW, sometimes a bit more but usually a lot less. The proposed Rolls-Royce "SMR" is theoretically capable of outputting 440MW. At that rating it's probably aimed at replacing Britain's existing AGRs which produce betw

  • Macron said six reactors with an option to build 8 additional others. 14 is the maximum number the French nuclear industry can build according to RTE which has consulted the French nuclear industry. RTE stands for Reseau de Transport d'Electricite,, the entity that manages most of the French grid. They could ramp up production but after 2050 if all goes to plan.

    And even 14 reactors plus an extension of many others still means a reduction of the nuclear part of their electricity mix. Not because they wanted

    One impetus behind the revival of nuclear is that Europe recently commissioned studies examining how much wind and solar they will need to fully replace existing energy sources and satisfy future needs. The answer was that they will need to mow down every living tree in Europe to cover the entire landscape with wind turbines and solar panels.

    So Germany and France are running in opposite directions with that finding.

    Germany is enthusiastically pursuing the "we need to destroy the environment to save it approach," having commenced destruction [wattsupwiththat.com] of about 5,000 acres of pristine 1,000 year-old forest to put up wind turbines.

    Wind and solar have terrible space efficiency and those are hard limits established by the density of the energy in the environment. It is a definite impossibility to engineer your way around that. Then, also, the intermittency problem of those requires spending several times the GDP of your nation on batteries.

    France is going 180 degrees the other direction by choosing the smallest possible energy footprint. The power density of nuclear is a zillion times higher than wind and solar.

    Fission works now and has feasible potential for orders-of-magnitude improvements in price per kWh. Unlike with wind and solar, there is a lot of room to engineer big improvements. Advanced small modular reactors mean not every reactor is a one-off design built on-site, but instead comes off a factory production line, greatly reducing design, manufacturing, licensing and construction costs. Passively safe designs rule out the possibility of meltdowns. Experimental seawater harvesting if fissionable materials continues to improve, with the possibility of a virtually endless supply of fuel. Even just modernizing conventional reactor design has reduced the number of parts to about 1/4 of a 1970s design. Wave reactor research continues to advance, improving the recyclability of fuel. Estimates are that with wave reactors and sea water harvesting we have enough fissionable materials on earth for about a billion years at current energy consumption levels, which might be enough time to get fusion reactors to breakeven.

           

    • we have enough fissionable materials on earth for about a billion years at current energy consumption levels, which might be enough time to get fusion reactors to breakeven.

      I'll believe it when I see it. Fusion power has been "only a billion years away" for over four billion years now.
