Nuclear proponents when trying to sell nuclear love to shout about how successful France is. Someone from France is telling you that actually, it's really not that great...and now France's nuclear program is terrible and the result of 20-30 years of neglect and politics? Also, which part of "nuclear plants are sensitive to environmental changes" didn't you get? If there's no cooling water, or the water is too hot, the plant can't run. How many times do people need to be told that with all the renewables coming onto the grid, we don't need more base load? We need storage. Also, wind keeps working just fine when the sun goes down. Do any of you geniuses realize that it's a lot more difficult for the grid to accommodate the injection of tens of gigawatts of power, than it is to handle tens of gigawatts of highly distributed generation and storage across a large region?Guess where utility companies are spending their money? Hint: not on nuclear. Nuclear is the most expensive form of electrical generation while wind and solar are the cheapest. Nuclear capacity takes a minimum of ten years, more like 20, to come online and then takes decades longer to go carbon-neutral. Solar and wind take months to deploy and are carbon neutral within a few years. Nuclear plants require a continuous, expensive, complicated supply chain and hundreds of people supervising and maintaining it. Solar farms require maintenance that just about any asshole with an electrician's license can handle, the panels last for decades, and can be recycled. Wind turbines require more maintenance but it's standard industrial electrical/mechanical stuff, just on a tall stick.

  Sure, France has it's own issues but they are not really related to the tech itself. Point me any other energy company which could have survived basically 20 years without proper investments and forced to sell back electricity to their competitors. I would even say that the tech is what made the grid still standing against all odds.

  Yes, intermittent (sun/wind) only could work with enough storage. Do you know if/when we could get enough safe storage ? My understanding is batteries is not possible at the scale we would need. Pumping water where it is possible would be nice, but not sure if it would be enough. Do we know the storage capacity than US for instance would need, if only using solar and wind ? Note that the cooling argument would be the same for coal or gas power plant. They work the same way. So, until enough storage is in place, we might need some base production, and it would require access to cold source (river or ocean). France had to reduce the activity of some nuclear power plants last summer because they have rules when it comes to river temperature. The next 8 reactors that France is planning to build would likely be build on the ocean's shore for that reason. The cost of nuclear electricity is mostly impacted by the cost of money. That is why the cost of electricity from a UK nuclear power plant is more expensive than from France nuclear power plant. The UK used private capital (higher interest) when France use gov funds (lower interest). It is correct that it takes time to build a plant, and it requires expertise. But it is also true that a power plant can run for decades (US and France pushing to 80 years) as anything in a plant can be upgraded over time (except the pool). Until there is an efficient storage technology that can be deployed at large scale, we might need to run some nuclear power plants. No idea for how long ?

    A counterintuitive alternative is to invest a fraction of the costs of nuclear in cleaning up emissions from coal plants. We seem to have swung too far by shutting down a reliable source of energy when mitigating technologies to filter emissions [1] and next generation cleaner extraction technologies [2] are coming online to massively improve coal driven electric power generation. These technologies are DoE funded and patented the former has been deployed in production at a 100 Mw plant the latter is at a pilot stage in a 30Mw research generator at a university. In any case coal is not going away and there is no single “answer” to the planet’s energy needs. A resilient grid requires a portfolio of energy sources including nuclear but it’s by no means the single answer as the title of the post suggests. Uranium is “carbon free” but “radioactive waste full” and creates multigenerational environmental debt in the form of waste - nuke proponents usually hand wave and talk in generalities when it comes to this topic. Note the comment that “90% of materials in a nuclear reactor can be recycled” deftly sidestepping the 10% that will live on in deadly form for thousands of years with no solution in sight.

    >Except if you add the cost of 12 hours of batteries to solar it's massively more expensive. Nobody knows what nuclear costs, because nobody knows what it will cost to handle the waste 10 years from now, let alone 100 or 1000 years from now.

    No but some are more resilient than others. It is much easier politically to shut a nuclear power station down than remove dirty wood burners from people's houses.

  Can you give an example of a power source that is resilient to politics? I struggle to imagine what that would even look like.

    Coal power plants, wind turbines and mostly anything else. They can end up catastrophic in a sense, but not to the same degree nuclear fission plants can end up.

      Coal has killed tens of millions from air pollution alone. Civilian nuclear power has probably killed on the order of a few thousand, at most. The studies that say millions have died as a result from Chernobyl is propaganda funded by Greenpeace and friends.

> It's just as easy to find confirmation that all the problems you listed are the result of neglect and politics of the past 20-30 years. This is always my objection to Nuclear. Nuclear's biggest drawback is that it requires proper maintenance and a stable regulatory environment to be safe. Our world is too political and tumultuous. You have to manage too many externalities. This is only going to get worse as our climate continues to change. I just don't see decades long nuclear projects helping us in the short term, and the disruptions on the horizon make long term governance of them problematic.

Neither solar nor wind power fulfills these requirements. The main goal should be to abandon coal and gas power plants as quickly as possible, and Germany showed that it is very hard / impossible without nuclear power.

Blaming things on neglect or politics just isn't useful. We need power sources that have some resilience to those things.

Exactly. Humans are part of the system, so human factors matter to reliability.

  No but some are more resilient than others. It is much easier politically to shut a nuclear power station down than remove dirty wood burners from people's houses.

Can you give an example of a power source that is resilient to politics? I struggle to imagine what that would even look like.

  Coal power plants, wind turbines and mostly anything else. They can end up catastrophic in a sense, but not to the same degree nuclear fission plants can end up.

    Coal has killed tens of millions from air pollution alone. Civilian nuclear power has probably killed on the order of a few thousand, at most. The studies that say millions have died as a result from Chernobyl is propaganda funded by Greenpeace and friends.

> It's just as easy to find confirmation that all the problems you listed are the result of neglect and politics of the past 20-30 years. This is always my objection to Nuclear. Nuclear's biggest drawback is that it requires proper maintenance and a stable regulatory environment to be safe. Our world is too political and tumultuous. You have to manage too many externalities. This is only going to get worse as our climate continues to change. I just don't see decades long nuclear projects helping us in the short term, and the disruptions on the horizon make long term governance of them problematic.
