    People do not want to ear this, but depending on your definition of clean, nuclear is as clean as solar, wind and batteries. No source of energy is free from death, carbon emissions and pollution. Solar, wind and batteries requires extensive mining for rare materials and carbon intensive factory production. If we check all factors again nuclear, the number are remarkably similar to solar, wind and batteries.

    In a world where gas, oil and coal exists, nuclear must be put on the same category as renewable. We cannot afford to close any nuclear power plant, as closing a nuclear power plant before the last coal power plant is closed, means we are killing people. Numbers do not lie.

      Based on a cursory skim through the article, it does not seem to be claiming that nuclear energy is a “dirty energy”.
      Cooling towers, as depicted in the thumbnail, are not exclusive to nuclear plants. Coal plants can have cooling towers as well.

      I’m agreed with you. The German Grüne logic doesn’t make much sense to close nuclear before coal.

      However for new production, solar and wind makes more fiscal and technological sense than new nuclear.

        I think even with solar, wind, tidal and perfect grid storage nuclear is still worth investing in, simply because its a useful technology to have in some space travel applications, in some cases even more useful than fusion power would theoretically be.

        Everyone hates getting stuck because it turns out that one tech from half the tech-tree ago was mandatory for progression.

        In the current European legislative environment yes. We lack common certification rules, standardized procurement and security standards that make sense. Nuclear in Europe is double the time to build and double the cost of nuclear in Japan. This was not always the case. France was able to decarbonized faster than any other big country in the world thanks to the rapid deployment of his fleet. If we fix that, new nuclear in Europe makes sense. We currently lack the technology and the industrial capacity to not be dependent on China for solar, wind and batteries. Nuclear provide energy when you need it, stabilize the grid and ultimately reduce the price of energy (like you see in Finland). The higher the share of renewable in the European grid, the higher the amount of batteries needed. In general one could argue that the best grid mix for lowering external dependencies and costs is 10% to 20% nuclear, and the rest hydro, solar, wind and batteries. In the north of Europe wind is a great resource, but in the most industrialized part of the south (Italian padana plain) the wind potential is very low, as the solar potential in winter when the fog would cover everything. The amount of connections to make a renewable only grid work on the European level are not trivial nor cheap, and we should do anything we can to promote and regulatory environment where the best tool for the job can be deployed.

          Is there sufficient uranium mining in the EU? If not then nuclear doesn’t make the EU energy-independent.

            cheap uranium can be bought from Canada and Kazakhstan. In Europe there are big reserves in Ukraine. But uranium can also be extracted from water. Getting uranium from the ocean is 3 to 5 times more expensive. But uranium is a minimal part of the cost of nuclear energy. So if we get uranium from the ocean, energy price will raise by 10% to 15%. On fossil fuel power plant the actual fuel is most of the cost of the energy. Furthermore you can buy uranium years in advance, making it much easier to prevent jump in market prices.

              I don’t know, somehow that doesn’t sound to me more independent than buying a shit ton of solar from China which gives 2 decades of runway to develop domestic production for replacement. Solar + sodium-ion which os already in production and cheaper than Li-Ion in China.

              I don’t mind nuclear btw.

                If we can do both we should do both. This is not nuclear vs renewable. They solve different problems. Modern nuclear reactor design like Terrapower are created to work with renewable (using molten salt energy storage). Humanity will not reduce the amount of energy it uses, and we need to force the electrification transition if we do not want to destroy our planet.

          I mean the industrial barriers to developing new nuclear energy are (AFAICT) similar to the industrial barriers to developing the production and Euro-sovereign supply chain for new battery solar and wind generation. Happy to be shown differently if you can point to me some differences that would have nuclear development require fewer physical resources, time or money.

          I think some development in Small Modular Reactor tech is promising. Any in-progress or in-operation nuclear should stay the course. But if there was one technology we could choose to either ride fully into or vastly increase development alongside nuclear and other energy sources, the drastic cut in costs for renewables with battery storage seem to me like the silver bullet to the climate crisis everyone was waiting for, we just need our governments to pursue it NOW. In Italy’s particular case, tidal energy seems very suitable due to its massive coast relative to land size.

            The main problem is that in europe there is no single regulatory body for the certification of nuclear reactor. That means that a nuclear reactor certified for france needs to be certified again for UK, Poland or Czechia. The requirements for nuclear are much higher then a solar power plant. Each single material and part needs to be certified and the entire production is tracked (material traceability, QA testing, chain of custody). A valve in a nuclear power plant cost 100 times more then the same valve in a coal plant. There are very few companies that deal with this level of paperwork required, this means often you need to create new production lines. Regulation in nuclear is not outcome oriented, but process oriented. So you do not have incentive to make everything more efficient: you do not care about the end result, you care about every single steps in the process. This make everything much longer and expensive. Post Fukushima raised a lot the cost of all design made before as new requirements caused to modify previous plants. This is one of the main reasons for the delay in nuclear deploy in the last 20 years.

              So you’re arguing that the cost and regulation barriers are higher than renewable development. Are those increased costs proportional to the benefit to the higher baseload, and would an equivalent baseload not be able to be met through battery storage?

                Yes, the barrier for nuclear is much much much higher then renewable development. We know that the same nuclear reactor costs 3.5 billion in china, 4.5 billion in japan, and 9 billion in Europe. That is a huge difference. This is not just a technology problem, but an issue about regulation and processes. I an not arguing for going back to the regulatory framework before Chernobyl and Fukushima, but to take some lessons from the world of aviation where safety is important, but outcome driven and pragmatic regarding costs.

                If we want SNR to succeed we need to make it so that you certify one reactor out of the factory line and then you can build a hundred more without to having to re-certify every single reactor.

                Battery can met the equivalent baseload. The problem is production capacity, cost, connections and the pollution caused by this deployment. Often is simply better to deploy more renewable then needed. Today you need curtailment to manage grid stability, the higher the percentage of nuclear is the higher the dependency on battery and curtailment is raising the cost of renewable.
