    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?

      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.

        >Nuclear has no real cons other than time/cost of deployment,

        That's not true. It'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't.

        Also of course each nuclear plant carries a nonzero chance of a trillion dollar incident (we'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.

        >t'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't realized it. Like batteries. They'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's the path to true energy independence.

        And anyway, europe still gets 70% of it'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.

            >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't do anything to protect themselves from it, and have to live with the consequences for 30+ years. That's much worse by any metric.

            Deepwater horizon was bad, but nowhere near as bad as Chernobyl or Fukushima. Also it wasn'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't exist is not rational.

              So we're not counting natural disasters that cause power infrastructure failure? I take it you don't consider the events of the Tohoku earthquake and tsunami to be a nuclear accident then.

              > With nuclear, people in Scotland are in danger from a plant in the Ukraine, can't do anything to protect themselves from it, and have to live with the consequences for 30+ years. That's much worse by any metric.

              And people in Scotland are in substantially greater danger from the emissions of coal plants in China.

              > Deepwater horizon was bad, but nowhere near as bad as Chernobyl or Fukushima.

              It was much worse in terms of environmental impact, particularly the area impacted.

              > Also it wasn't a power plant

              I don't see any reason to limit the discussion to electrical power plants.

              > Risk is often defined as consequence x likelihood

              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's risk is unique - uniquely low. I fully agree this should be accepted and considered in any discussion.

                Of course not, if I did that's 20 000 dead from a "nuclear accident" right there. But that would be dishonest and silly, and I aim for rationality.

                >And people in Scotland are in substantially greater danger from the emissions of coal plants in China

                Not even if you assign all the blame of global warming to chinese coal plants would this be even remotely true.

                >I don't see any reason to limit the discussion to electrical power plants.

                You responded to a claim that no other power plant represent as great a risk at a nuclear power plant.

                Maybe you should have created a new thread saying something like "a nuclear plant is not as bad as the entire fossil fuel industry worldwide"? ;-)

                >The consequences are no worse than the dominant alternatives

                You completely ignored the facts that clearly tell you that the consequences are orders of magnitude worse.

                That's no way to convince anyone. Just saying.

                  So you are in a phase where coal is safer than nuclear? Sorry but that's bullshit. German early nuclear phaseout did already cause due to pollution half of total nr of estimated deaths from Chernobyl per UN assuming LNT is true at low doses. It's you that are ignoring facts and spread literally fossils fuel propaganda to justify your antinuclear position

                    The permanent truth phase yes. Coal is so much safer than nuclear that a comparison is hardly meaningful.

                    Let me put it this way - If coal power plants were run with as much security as nuclear plants they wouldn't kill mosquitoes sleeping in their chimneys. If nuclear power plants were run with as little security as coal plants however, we would not be here to have this discussion.

                    You seem to be well aware of the dangers of fossil fuels, but you come across as entirely ignorant of the dangers of nuclear power. Good decisions need knowledge of both.

                    I'm as anti coal as I am anti nuclear because both are terrible ideas. Renewables, batteries, e-fuels and other storage options are here now. They're better, faster, cheaper, safer. Let's do that.
