We were extremely lucky with Chernobyl that young men sacrificed themselves, else a large chunk of Europe would be uninhabitable.
We were extremely lucky with Fukushima all the radiated water just went into the ocean. When it was going down there was nothing we could do but stand back and watch how bad it got.
Of course on a regular day nuclear is safe, but every now and then things go extremely badly, and sooner or later we’re not going to get so lucky. We will simply have to watch and retreat from death.
Deepwater horizon was really bad. Plenty of coal accidents are real bad.
Not having energy is really bad.
Nuclear is the safest form of energy - and catastrophic failures are found in other forms of energy production.
We have tools, equipment and people to put out oil rig fires, clean up oil spills and all that.
Obviously Exxon Valdez was very, very bad. So was deep water horizon. Now imagine they were nuclear plantS that went bad and we didn’t get lucky like in the past. It would be many orders of magnitudes worse, for tens of thousands of years.
Now imagine humans can't even go within a few hundred meters to clean anything up, and we have no robots that can either.
Also imagine that humans can't live within 500km ever again.
Nuclear is clearly the best option, right up until the point it's the worst possible thing for humans and planet earth, which seems to happen about every 30 years or so. As I said, we've been lucky with it so far.
In other words, on a risk adjusted basis, the data continually shows nuclear is the safest and most economical bet for removing fossil fuels and all their problems from the energy mix. You’d need a a relative fuckton of very very bad accidents where everything went wrong and by all accounts that doesn’t really happen.
Given how little time we have to react, and how long it takes to build a nuclear plant (and how expensive they are), putting our hopes on nuclear this late in the game is foolhardy and will never save us.
We have no choice but to go with what will have a meaningful impact in the immediate future (5 year horizon) - wind, solar, hydro. Many countries are already past 50% renewable, and many are climbing towards 100%.
Oh, and mass production of carbon zeolithes to regenerate the sucked empty agricultural fields, to make them into something like 'terra preta' without having to use too much fertilizer, instead of uselessly sequestrating it somewhere underground.
Terraforming, so to speak. Like the 'atmospheric processors' from Alien II(Aliens).
edit: Instead of thinking all the raw materials for wind,solar&batteries grow on trees, without any externalities, sustainability problems, and no emissions at all. Which is a fucking cargo cult!
Uh huh. And when exactly will they be online and performing all this work for us?
As well as the time and cost to build the nukes, how much time and money will it take to build the machines to suck the carbon out of the air.
I'm all for solutions, but 30+ years isn't going to cut it. 10 years is a huge risk.
Even after a few decades late into the game?
What is so hard to get about the idea that we can actually modulate the greenhouse gasses in our atmosphere, now that we know that and how they influence our living conditions?
It would even make sense to have something like this in case of the next supervolcano eruption. Call it 'weather control done right', if you like.
Yes, of course that is a great hypothetical option for 30-50 years from now.
We and our children don't have time to wait for that.
Next you're going to tell me if I just wait till fusion works we'll all be saved and can power these "atmospheric processors" with those!
Nope, I won't. Because anything except aneutronic fusion will be much dirtier than the 'nukes' we have now. Which is hypothetical right now, and maybe stays so forever.
Which can't be said about 'nukes', neither the ones we have, or the ones we could have with a little bit of more investment into materials science. (Liquid salt, etc.)
We and our children won't make it with 'renewables' alone, because they emit at least as much greenhouse gasses, or more when you consider all the externalities going into their production. They are not the solution.
Edit: /me mumbling something like 'Look into fucking GESAMTSTOFFMENGENKREISLAUF'
It’s fair to bring up hypotheticals, but you have to do it for everything you’re comparing!
It’s especially important to include “never happened” scenarios for brand new, or lightly used, methods of energy extraction!
What are the worst case scenarios for windmills? Solar panels?
Imagine a major Soviet-level accident at a rare earth element mine.
Imagine a large supply of rare earth metals are improperly labeled.
It might not be as bad as a major nuclear accident … then again maybe it would be.
Not really. If you actually measure it, its not actually that bad.
> We were extremely lucky with Chernobyl that young men sacrificed themselves, else a large chunk of Europe would be uninhabitable.
Often claimed but, the scientific bases for this claim is beyond shake. Maybe at the very worse you could say that radiation that was slightly dangerous would have been measurable all over Europe, but even that is a stretch.
> The problem is when they go bad, it gets really bad.
Fukushima killed people because of rush unnecessary evacuations. Nobody actually died of radiation, maybe a very small group of people will have a slightly higher likely-hood of getting cancer, but even that will most likely not even be measruable.
The actual earth quake and the water killed far more people. The nuclear event made the news because its a novelty, while we have seen many people killed by earthquake and water.
> sooner or later we’re not going to get so lucky.
Given that safety increases over time, even the chance of a minor incident is increasingly less likely.
And if we actually built modern plants not 1970 design we could make it almost impossible for any significant risk to exist at all. But of course research and progress has essentially been stopped.
It is easy to talk for someone who has not experienced the fallout of an nuclear powerplant burning a few countries over. Experiencing such a thing (hopefully understandably) changes how favourable people see the technology.
On top of that the question of safe nuclear waste storage is far from solved in dense Europe. From an ethical standpoint I think an approach of "Lol we need energy now, let's have later generations deal with this and pay for it" highly questionable.
If you produce one kW/h of nuclear energy today, my opinion is that the costs of the potential fallout in the weird rare cataatrophe scenario and the waste storage for the whole lifetime of the waste need to be paid ahead. That, however would make nuclear uneconmical.

While it it not the same as experiencing this terror firsthand, my grandparents lived not very far away from you during the Chernobyl incident. It was very frightening.
Also, I live not so far away from Three Mile Island here in the USA. As well as very several currently functioning nuclear plants.
So while it is "easy" for me to talk about nuclear power, it is not purely fantasy for me.

I am looking at this from the perspective of global warming, which will have disastrous consequences for many billions of people.
Should we also add the costs of global warming to each kW/h of energy produced by coal or natural gas?
Yes. That's what carbon pricing/taxes is all about after all: counting the externalities.
Its basically not statically significant.
There might be a somewhat larger effects on some treatable cancers, but the numbers are still incredibly small compared with the fear mongering and of course compared with other forms of energy used back then.

You are like better of with having a nuclear fallout every could decades rather then a coal plant.
As opposed to many other reliable generation types which have global catastrophic consequences† while running normally.
And by "reliable" I mean can consistently provide power more that 50% of the time:
* https://en.wikipedia.org/wiki/Capacity_factor#Capacity_facto...
† E.g., climate change.
Compare it dollar for dollar.
You can get a lot of curtailment, oversupply, and storage for $12/W
Also if you look at France, nuclear's not doing so hot on the availability front.
Meanwhile, in Ontario, Canada, where I live, nuclear+hydro generate base load 24/7 with little issue:
They're hardly the super-100%-reliable baseload advertised, or anything approaching 'too cheap to meter' though.
Of course, it takes a significant amount diesel fuel, energy, and mining to make EV related equipment, too.
A full life-cycle analysis of nuclear power isn't really favorable. Germany is a net power exporter. Sure, there is more to it since the energy isn't generated in correct place at the right time, the infrastructure has problems and then some.
But in the end nuclear isn't a solution here. Expensive, slow, another resource dependence and nobody knows yet how to get cheap uranium in the future. The developments previously are going in the correct direction and that direction did not include nuclear power in the meantime.
There are ~450 plants currently operating in the world, with an average age of multiple decades. Plus all the ones that have been retired. That's a lot of data.
You don't really have to take anybody's word for it. They're safe.
They are not zero-risk, because literally nothing is. We also absolutely know the risks of fossil fuels (the planet is burning, and buyers potentially become dependent on hostile countries like Russia) and the current limitations of renewable energy sources.
So, to answer your questions: that is how you judge their potential safety in Germany or anywhere else.
