    It is sad that this has become a topic of the culture wars. Nothing good comes out of this, certainly not a rational weighing of the pros and cons of nuclear power.

    I’m particularly interested in how they plan to finance reactors in a grid dominated by solar. I wouldn’t be surprised if they legally allow the building of new reactors but then fail to find investors. But perhaps they plan on using them as some sort of strategic assets and will just run them at a loss?

      > certainly not a rational weighing of the pros and cons of nuclear power.

      Nuclear has no real cons other than time/cost of deployment, and it should be a no brainer for a place like Europe without significant energy resources. Once the power plant is built, it provides 50+ years of nearly free energy. It's that or buying gas from Russia.

        Cost and time seem like a pretty important con to me.

        Yes no real cons if we exclude the small con of being completely economically unviable.

        How about nuclear fuel still being dependent on either russia or us? and that is just one reason.

          Conspiracy hat time: I think this is the main reason it's being pushed so hard. The US and Russia feel threatened by the rise of renewables and will do anything to get countries dependent on them again.

            This isn't right, in fact one of the main reasons for building nuclear power plants is independence from politically unstable places like Russia and the Mideast.

                There are some better mines in different areas of course, but it is available across most of the planet. Processing it is way harder than finding a source of it, but that is also a solved problem, you just gotta put in the capital to build it.

                    But it also secures your energy needs independent from anybody else and still scales. Solar lasts a long time, but not nearly as many countries have the minerals for building more panels and batteries as they do uranium refinement.

                      What? Solar panels last virtually forever. The oft-quoted 25 years is for a 30% efficiency loss, they actually last way longer.

                      Any country that can figure out uranium processing can figure out solar panel production, and they are made entirely from common materials with advanced processing steps. I'm not sure about batteries though.

        &gt; it should be a no brainer for a place like Europe without significant energy resources.

        The uranium needs to be regularly replaced. Europe currently imports virtually all of the uranium used by its nuclear power plants. While Europe has some decommissioned uranium mines, they would have to be reopened, but the known deposits are estimated to cover less than the 50 years you cite, at current levels of nuclear production (much less when expanding production).

        So if this is about energy independence rather than cost, I’m not sure that it would be such a great win.

        1. icantevenhold · · focus · HN ↗
          Idk we can import uranium from lots of places; i think currently mostly from Canada.

          But I just don’t get why it’s being discussed at all - its obviously so much more expensive and time consuming to build than the alternatives

        2. philipkglass · · focus · HN ↗
          Nuclear fuel rods get used for 1-2 years before they need to be replaced. This is much longer than it takes to burn a shipload of liquefied natural gas, though it&#x27;s much shorter than it takes for solar panels or grid scale batteries to need replacement. Both nuclear energy and renewable energy are less sensitive to supply shocks than fossil energy, even if Europe doesn&#x27;t reduce the percentage of its energy needs that depend on imports.

            Yes, but the parent was implying 50+ years of nothing to worry about once a plant is built.
            1. AngryData · · focus · HN ↗
              It would cost a bit more is the worst case if you had to build your own centerfuges, uranium is not all that rare. And a single ship could carry a decades worth of fuel (not that I recommend a decade of fuel on a single ship), so even if shipping was costly it would be cheap compared to the actual fuel refinement. You couldn&#x27;t Hormuz a uranium fuel supply because it doesn&#x27;t take thousands of ships or miles of pipeline to deliver.

              So maybe not worry free, but if you are able to run nuclear reactors for power to start with, obtaining fuel for them in any scenario shouldn&#x27;t be impossible. You got atleast a year or two lead time between refuelings, and it might be able to be stretched a little longer in an emergency. And even more time if you hold some in reserve.

        3. Emma_Goldman · · focus · HN ↗
          Australia and Canada are top producers of uranium ore, and uranium ore is a small fraction of total lifecycle costs. Given a ~2 year refuelling cycle and the possibility of stockpiling uranium, this is very far from an interruption to oil and gas flows - which you need a continuous supply of. Security isn&#x27;t just a function of autarkic raw material supplies.

          There are many more deposits to explore, like Sweden. And we can start doing purex+mox recycling to extend operation further

        Cost of deployment is a massive consideration in our not-yet-post-scarcity society.

        It takes billions to certify a nuclear power plant, and it takes billions more to re-certify it every few decades, to say nothing of the costs of modernization.

        To be clear, I consider myself generally pro-nuclear power, but let&#x27;s not ignore the massive upfront and ongoing capital and operational costs that really undermine this idea that it&#x27;s free power.

          It&#x27;s perfectly figured out. Just entomb it in concrete and store it on site. All spent nuclear fuel to date combined would quite comfortably fit in an average Walmart parking lot. It&#x27;s a complete non-issue. And if we&#x27;d get really desperate, the spent fuel could be re-enriched.

        &gt;Nuclear has no real cons other than time&#x2F;cost of deployment,

        That&#x27;s not true. It&#x27;s extremely expensive to operate for one, so expensive in fact that nobody in the private sector wants to do it without having nation states basically guarantee profits for the lifetime of the plant or accept all liability. Which in several countries means that he operator is the nation state. Like in France.

        The profits are guaranteed by collecting extra taxes from the population, not by increasing the price of electricity. Which is why people believe France has cheap electricity when they really don&#x27;t.

        Also of course each nuclear plant carries a nonzero chance of a trillion dollar incident (we&#x27;ve had two so far) as well as a nonzero chance of millions of casualties. Both these cons are entirely unique to nuclear power plants. No hydro plant, solar plant, wind farm, coal, oil or gas plant can cause as much damage as a nuclear plant.

        &gt;t&#x27;s that or buying gas from Russia.

        Not at all, there are many options (including buying gas from someone else). Some options got viable so recently people still haven&#x27;t realized it. Like batteries. They&#x27;re cheap now, you know, and China can build as many as we want. China has also caused a severe drop in the cost of hydrolyzers, used to create e-fuel. E-fuel means you can use solar power in winter and during night, which removes the remaining weakness of renewable sources. Europe should spend every eurocent in that direction instead of nuclear. That&#x27;s the path to true energy independence.

        And anyway, europe still gets 70% of it&#x27;s nuclear fuel from Russia. How is that better than gas?

          The Banqiao dam failure killed 250,000 people in a single incident. Pollution from coal plants running normally causes 1 million premature deaths per year. The deepwater horizon spill was a $100 billion disaster with an environmental impact greater than any nuclear incident. The Centralia fires in PA are still burning after over 60 years and lead to a town being abandoned. Nuclear is not uniquely risky by any rational metric.

            &gt;The Banqiao dam failure killed 250,000 people in a single incident.

            The incident was a typhoon that caused 60 dam failures in a densely populated area prone to flooding. Estimates range from 26000 to 240000 people dead, but rationally one has to assume the typhoon would have caused some damage in these areas even without the dams.

            So claiming this was a single hydro dam causing 250 000 dead is hardly rational.

            If you live in a narrow valley downstream from a dam you are aware of the danger. You as an individual can take action to protect yourself. If you live upstream by even 10 feet you are in no danger at all from the dam.

            With nuclear, people in Scotland are in danger from a plant in the Ukraine, can&#x27;t do anything to protect themselves from it, and have to live with the consequences for 30+ years. That&#x27;s much worse by any metric.

            Deepwater horizon was bad, but nowhere near as bad as Chernobyl or Fukushima. Also it wasn&#x27;t a power plant, not even indirectly as oil is mostly used for transportation, not electricity. Chernobyl and Fukushima were power plants.

            So again, there is just no comparison between nuclear plants and any other power plant. Nuclear really does have a unique level of risk.

            Risk is often defined as consequence x likelihood, and for nuclear the consequence is immense. Meaning effort has to be spent keeping the likelihood extremely small, in order for the risk to be low.

            This has to be accepted and considered in any discussion about nuclear power. Pretending it doesn&#x27;t exist is not rational.

              I was being generous in only looking at consequences without considering likelihood. The consequences are no worse than the dominant alternatives, but the likelihood has been astronomically less, hence Nuclear has been the safest power source ever utilized by mankind. So yes, in a way nuclear&#x27;s risk is unique - uniquely low. I fully agree this should be accepted and considered in any discussion.

            It&#x27;s not, the estimated production cost for existing swiss nuclear plants is 4-6 centimes per kWh, which is already expensive electricity and frequently higher than the market prices today. That is also the self-cost price, meaning whenever the market pays less for electricity, ch nuclear plants lose money.

            And as always, swiss taxpayers cover that loss so you won&#x27;t ever see it in the operators financial reports.

            Also worth noting is that EDF in France sells for 7 cents after being bailed out when sellng at 4 cents. This is not cheap electricity.

            &gt; What non zero chance of millions of casualties?

            Just to take one trivial example:

            If nobody is able to refill the water in spent fuel pools at any nuclear plant, they will catch fire. Assuming a radial spread of the fallout it will be near guaranteed lethal for at least 50 miles, probably lethal for some 500 miles, and you &quot;won&#x27;t want to live there&quot; for even further than that. And this will remain the case for millennia to decades, depending on weather and distance.

            So basically 500 miles radius, uninhabitable for several generations if you run out of water.

            Then consider that Switzerland is covered by a circle of some 120 miles, and has a population of several million.

            Do you think the 4-6 centimes per kWh covers a scenario like that? I don&#x27;t. Good thing Switzerland has lots of water...

              The price includes their profit margin. Even if they sell at lower, they&#x27;ll still make profit, just less.

              The claim about swiss taxpayers is bullshit, please stop spreading it, there&#x27;s no proof to this whatsoever. Swiss nuclear plants operation is not subsidized.

              Edf was not bailed out. It was renationalized (albeit state was always majority owner) to push for construction of epr2. EDF debt to EBITDA is healthy. It made profit pretty much every single year despite arenh, except 2022. EDF could definitely operate their npp more profitable but that&#x27;s another story.

              But even if we assume that 9bn transaction was a subsidy, do you realize it&#x27;s merely half of what Germany is spending for EEG alone EACH YEAR?

                It&#x27;s not nonsense but you made a different statement than I.

                Switzerland doesn&#x27;t use market prices. Electricity in Switzerland is regulated so they pay vastly more than the european market at most times.

                This Sunday for example, Germany enjoyed spot wholesale prices of 2 centimes per kWh while Switzerland had 12. You can verify the German prices on nordpool and an equivalent swiss energy market site.

                Citizens in Switzerland pay much more than wholesale, averaging over 20 centimes last year. They are forced to do so by regulations.

                When you force your population, aka the taxpayers, to pay 5-10x as much for electricity as it costs in the open market you using taxpayer money to subsidize electricity.

                You follow?

                &gt;Edf was not bailed out. It was renationalized

                Thats synonymous, and it was actually the second time EDF were bailed out, France had to pay for the overruns on the plant in Finland too. Lucky Finland!

                The mechanism varies by country, but the bottom line is that taxpayers always have to pay for nuclear. They have no choice.

                There is no option to walk away, you can&#x27;t leave it, it has to be taken care of. Every other power plant you can shut down and walk away but nuclear is, again, unique in this respect.

                When all the swiss nuclear operators go bankrupt, the swiss will still have to pay people to operate the plants, or decommision them, and then store the waste, for longer than Rolex has existed as a company.

                Nobody else will. So it&#x27;s the taxpayers, always.

                The spent fuel fire will be the most terrible thing that happened that day, unless the cause was an actual nuclear weapon strike.

        2. Even that cost is only obtained by accounting tricks, basically arguing the life of the plant is 60 years;

        4. Processing of uranium ore into fuel creates is an unsolved problem when it comes to waste byproducts eg UF6;

        5. Processing and storage of spent fuel is an unsolved problem. No, you can&#x27;t just stick it in a cave. Most spent fuel requires active cooling for years, possibly decades;

        6. Long term investment in maintenance is super-important and something that particularly private companies are incredibly bad at as evidence by the infrastructure management of every private utility in the US;

        7. They take 15-25 years to build, typically, if you&#x27;re anyone but China. Who know how cheap the alternatives will be by then? Look at solar&#x27;s price collapse;

        8. SMR does not work and will not work. It&#x27;s a myth sold to government to siphon grants;

        9. The cost of a catastrophe of a single plant is many orders of magnitude higher than any other power plants. Examples: Chernobyl, Fukushima. And yes I can already feel the hand-waving away of &quot;outliers&quot;;

        10. No nuclear power plant has ever been built without significant government subsidies; and

        11. No nuclear power plant pays the true insurance cost. Those costs will ultimately fall onto the taxpayer who will typically enjoy none of the proits.

          Do fossil fuel plants pay co2 costs, or insurance costs for killing the planet? Well, it wouldn&#x27;t make any sense, since it&#x27;s not accidents that kill in that case, but the steady state.

          The radiation from coal power alone (excluding accidents) kills more people every single year than nuclear power has killed in its entire existence (even including accidents).

          About waste: somehow, this is a solved problem (at scale) ? Fast breeder reactor, half life ~= 30 years (IIRC)

          From your message, I understand that your country fails to build nuclear plant in a timely fashion but that other (china) can. Seems like a lack of skill&#x2F;willingness to me, not a technical issue.
