    14 years and 35 billion (combined with #4 which has not been finished) and didn’t generate a single kWh in anger until now. Put the same investment into renewables and it would generate similar or greater energy and would start doing so within a year.

    The argument against nuclear now is not about safety. It is about money. Nuclear simply cannot compete without massive subsidies.

      France was able to output 2 reactors per year at 1,5 billion of euros per 1000MW for more than 2 decades during the 70’s to 90’s. The whole French nuclear industry has cost around 130-150 billions between 1960 and 2010, including researches, build and maintenance of France’s whole nuclear fleet.

      A 1000MW reactor, at current French electricity price and for a 80% capacity factor, generates 1,4 billion of euros worth of electricity per year, for a minimum of 60 years.

      Nuclear is not costly, and can absolutely compete by itself, if you don’t sabotage it and plan it right.

        I would be very interested to know why the trend has moved away from building reactors in time and within a reasonable budget. It seems that most projects after the turn of the millennium haven’t been cost effective.

        Why did we manage to build reactors well before but not now?

          Every year a reactor operates is a year of experiencing new ways they suck. The fixes and added complexities are rolled into the next reactor.

          Thr grifters running the show also learn new ways to grift, so the small new delays and costs are amplified.

          For older reactors the costs this imposes are rolled into operational budgets (and more often than not reactors are closed as unprofitable and the public or ratepayers are left holding the bag).

          Additionally regulatory agencies keep finding new instances of fraud, stopping these adds costs to the regulator and regulatee.

          This has happened since well before three mile island, so all misdirections to “scare mongering about meltdowns” are lies (the rate of cost escalation actually slowed significantly after three mile island).

          Chernobyl and Fukushima. These two events, which between them account for a few thousand deaths at most (compared with the tens of thousands of deaths caused by coal in Europe alone, for example), triggered a panic fear of nuclear power.

          For decades, the nuclear industry has been abandoned and sabotaged, with projects such as Phénix, Superphénix and Astrid in France, and virtually all new reactor projects, cancelled due to anti-nuclear opposition.

          Competent nuclear engineers and technicians have retired without being able to pass on their know-how, and cutting-edge nuclear-related industries have disappeared or been converted.

          We can also thank the Germans for sabotaging the EPR. We started the project together, they forced us to add a lot of totally unjustified redundancies and safety features that made the prototype very complex and therefore costly to build, and then they slammed the door on us.

            Competent nuclear engineers and technicians have retired without being able to pass on their know-how, and cutting-edge nuclear-related industries have disappeared or been converted.

            This same fear has been enough to fund SLS and Ariane programs. Basically to avoid the loss of a capability in case it’s needed later on. For some reason it doesn’t seem to apply to nuclear. And now people are complaining that building new reactors is expensive, arguably at least partially due to the supply chains no longer existing in the same scale as before.

              If loss of expertise were the cause, then there would have been a cost minimum in the late 80s when the maximum number of engineers had 5-15 years of experience.

              Instead costs rose for each new reactor (including repeat builds of each model).

              This theory has no explanatory power over reality and predicts the opposite of what happened.

                Should the delays and subsequent costs overruns then be simply attributed to increased regulatory complexity or corporate greed?

                I’m looking at the list of reactors in France, most of the builds during the last millennium were completed in more or less 10 years. Then there was a gap, and the new one is taking way longer than previous ones.

                Same thing has happened in many other countries. Including finland, where at first we got 4 reactors in 6-10 years, and then after a gap of 25 years the next reactor was a clusterfuck that took almost 20years to build.

                Both of these reactors are of the same design, and the issues are at least partially attributed to the company having forgot how to manage such large projects due to the years long gap in construction.

                  Part is the neoliberal economic model is really really bad at big projects. Part is the regulations and engineering complexity involved in not having them all shut down because they caught fire or the steam generators corroded (almost every program has “cheap” reactors at the beginning which have massive maintenance issues and leaks 10-30 years later, followed by expensive ones with massive delays). Part is corporate greed. Part is revealing and stopping rampant fraud and finding safety-compromising cost-cutting measures. Part is the lack of pressure from the military to make it happen as there is no longer a need for as much Plutonium. Part is that there actually are some semblance of environmental laws. Part is the fossil fuel industry interfering (as they do with all non-fossil-fuels).

        Except those reactors are off 30-50% of the time due to shoddy construction, €1.5/W in 2023 money is pure fiction, and overnight costs with free capital aren’t real costs once you adjust for inflation and stop cherry picking the first reactors before negative learning rates kicked in.

          Except those reactors are off 30-50% of the time due to shoddy construction

          For French nuclear power, the lowest load factor ever recorded is 54% in 2022. The cause is the number of maintenance operations postponed because of COVID, plus a corrosion problem detected on several reactors of the same generation, which have since been repaired.

          • This is an extremely unlikely combination of circumstances, on the one hand
          • On the other hand, it wouldn’t have had any consequences if we’d had more redundancy, and hadn’t suddenly stopped building reactors for 25 years.
          • Despite this, nuclear power still has a load factor 2x higher than French wind or solar power.

          The rest of the time, the load factor of French nuclear power hovers around 70-75%, and that’s not due to bad design, it’s a strategy. I’ll let you read this link to learn more.

          €1.5/W in 2023 money is pure fiction

          Of course it does. But the fact is that french nuclear power has paid for itself dozens of times over. It’s factual, it’s historical.

          and overnight costs with free capital aren’t real costs once you adjust for inflation and stop cherry picking the first reactors before negative learning rates kicked in.

            Yes it was a “strategy” for EDF to go tens of billions into debt, and the other 30-50% of french power infrastructure is there just for fun. These mental gymnastics are incredibly tiresome.

                More deranged doublethink.

                ARENH can’t be causing losses if the price it sets is profitable (so by citing it you are claiming that the french nuclear fleet has never broken even).

                It also can’t be causing a production shortfall requiring buying expensive hydro if the reactors are off because of a “strategy”.

                Your debt doesn’t go up every year if you’re making a profit.

                Deferring maintenance doesn’t make costs magically vanish.

                Decomissioning, waste management and hundreds of billions for license extensions are also completely unfunded. So the french people were just bilked another €10 billion for taking on a larger share of a half trillion dollar liability.

      Renewables and nuclear play different sports.

      Renewables are better for most of our needs but there is a backbone need of base power. Nuclear is an expensive but clean way to provide that.

        By my very very very rough calculations, you could build a large scale solar farm with 3x power output and have enough money left over to build a 33GWh battery. That would more than cover a continuous supply of 1GW.

        That video completely ignores decommissioning costs for nuclear power plants and long-term nuclear waste storage costs in its calculation. Only in the levelized cost of electricity comparison does it show that nuclear is by far the most expensive way of generating electricity, and that it simply can’t compete with renewables on cost.

        People love to look at nuclear power plants that are up and running and calculate electricity generation costs based just on operating costs - while ignoring construction costs, decommissioning costs, and waste disposal costs.

          The cost of storing nuclear waste for a running plant is only a few hundred thousand a year; basically just just salary for a few people to transport it to a big hole in the ground.

          Decommissioning costs a few hundred million, which sounds like a lot, but for a project that lasts for decades it’s basically nothing.

            Estimated total cost of decommissioning in the UK is £120bn. But it’s going to take 100 years to do it… so yay lots of rotting radioactive buildings for the next century.

            The nuclear waste storage facility cost 53bn to build, let alone run… so way off your ‘few hundred thousand a year’.

              That’s for way more than just one plant, and there’s a lot more going on that resulted in such a high price tag. That isn’t normal.

              The nuclear waste storage facility cost 53bn to build, let alone run

              It’s a reinforced hole in the ground, designed to last a long, long time after humans forget it exists. Of course it cost money to build, but now it’s just there. It doesn’t cost anything for it to continue to exist. Maybe there’s a little security or staff for some purpose, but I don’t know what they would even do.

                No, that’s pretty normal. Current experience with decommissioning German nuclear power plants show that the cost is about $1.2 billion per power plant, and that decommissioning takes about 20 years.

                Of course it cost money to build, but now it’s just there.

                That doesn’t mean you simply get to ignore the $53 billion it cost to dig that hole.

              The Department estimates that continued operation of the current fleet of nuclear power reactors could ~70,000 metric tons of uranium * increase the total inventory of spent fuel from 70,000 metric tons of uranium to 140,000 metric tons of uranium. Nearly all of this spent fuel is being stored at the reactor sites where it was generated, either submerged in pools of water (wet storage) or in shielded casks (dry storage). The Dept of Energy

              Those must be some big fucking trucks. And as far as I know, only Finland has actually developed any long-term storage which could be considered safe.

              Nuclear is fine, but nuclear fanboi takes are similar to weed fanbois, it’s not a perfect solution.

        There are plenty of firming options (battery, pumped hydro, flywheels etc) which deliver reliability for a fraction of the price of this boondoggle. Not to mention a diverse portfolio of renewable technologies spread over a large geographical area is actually quite stable. When the sun isn’t shining in one area, the wind may be blowing or the sun shining in another area.

          Those can only hold enough power for minutes or hours.

          We need to be able to store power from the summer until the winter. Months. We need to store energy from when the sun is shining in July until it’s not in December.

          The only possible way to do that now is to store it as hydrogen or hydrocarbons. That infrastructure is currently very lossy, expensive, and only hypothetical.

            You don’t need power storage for months, if you combine different renewable sources and have power lines connecting different areas. Wind and solar complement each other usually.

            You need to be able to bridge a few weeks though, because there will be gaps, but you don’t need to store solar power for half a year to make it. It is still a big issue, but no need to exaggerate.

            This idea they can only hold for minutes or hours is simply not true not to mention the entire premise is false. Only the cloudiest of days the solar panels produce 20% what they do on the sunniest days that means you only need to build out 5 times the expected output to always be able to produce what you need during sunny hourse. That means you only need to have battery backup for 16 hours. Something that’s completely feasible. The idea batteries can’t hold power for months isn’t true it’s that it’s not currently economical. How long do you think your electronics take to get from the plant to the store till you buy it and turn it on. If we’re talking about cost then let’s look at this plant. 1.1GW nuclear reactor costs 35 billion and 15 years. A solar farm built out to 5 times capacity would cost roughly 6 billion. Now triple that for battery costs if you want 24/7 electricity were on the order of 18 billion. That’s nearly half the cost and this is being very conservative assuming you want this to be a baseload supplier but will output way more most of the time. Now you will have nearly free electricity during most of the year that other industries could take advantage of like aluminum processing or something like that.
