    I don't understand this argument, isn't Japan known for its earthquakes? 
Chernobyl has often been characterized as the result of a corrupt and incompetent late-stage USSR, whereas post-WWII Japan is seen as a generally well-run country.

I'm not agreeing or disagreeing with that, just trying to describe public opinion.

Re:Germany extends lifetime of all 3 remaining nuclear plants by avgcorrection on Monday October 17, 2022 @04:41PM (#33239255)
You’re not countering the implicit argument that Germany won’t have a problem with earthquakes ruining their nuclear powerplants.

Germany is also a “well-run country” if you want to run with the old anti-Soviet argument.

Re:Germany extends lifetime of all 3 remaining nuclear plants by johannes1234321 on Monday October 17, 2022 @04:49PM (#33239333)
It's not fully an objective argument, butnan emotional. "Even Japan can't run them safely!" Where Japan is known for its precision and strict following of rules (perception!)

Yes, rationally the maths is a lot different, but countering emotions with facts is hard. (And then consider facts like long term deposition of nuclear waste etc.)

As compared to the Germans? Supposed rule-sticklers without earthquakes.

FWIW, I'm a fan of nucear, but ... they don't have to counter that argument. It doesn't have to be earthquakes - it can be 1 of 100 problems. Japan knew they have to deal with earthquakes and didn't. What should make people more comfortable that Germany will be able to safeguard against their known risks?

The safety of nuclear power plants isn't exactly some great unknown.

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.

Re:Germany extends lifetime of all 3 remaining nuclear plants by grecy on Monday October 17, 2022 @07:11PM (#33240749)
The problem is when they go bad, it gets really bad.

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.

Re:Germany extends lifetime of all 3 remaining nuclear plants by grecy on Monday October 17, 2022 @07:37PM (#33241027)
The difference is even when coal or oil goes “worst case scenario” bad, it’s still entirely manageable.

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.

Re:Germany extends lifetime of all 3 remaining nuclear plants by grecy on Monday October 17, 2022 @10:13PM (#33242182)
Absolutely those are horrifically bad.

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.

Re:Germany extends lifetime of all 3 remaining nuclear plants by vlovich123 on Monday October 17, 2022 @10:47PM (#33242406)
This is the core problem. In this thread people keep referencing the data of the actual historical track record and you’re bringing up imaginary scenarios that haven’t existed and might never. Of course, the flip side argument is that past performance is not indicative of future results. Still, the track record approach feels like a better way to evaluate because a) non-green alternatives are waaaay worse b) green alternatives have a comparable number of deaths per MWh produced c) nuclear can reasonably ween us off fossil fuels d) if you actually invest in technology and make the regulatory environment sane, over time the cost and risk of nuclear decrease really rapidly.

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.

Re:Germany extends lifetime of all 3 remaining nuclear plants by grecy on Tuesday October 18, 2022 @12:35AM (#33243024)
The time to start building tons of new nuclear plants was 20 years ago.

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%.

You are thinking too small. With enough 'nukes' we could suck the carbon out of the atmosphere, and use that to make syngas/synfuels for the applications where it would be impractical to replace them. That alone would be almost carbon neutral. Similar for hydrogen production by electrolysis and process heat for many industrial applications.

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.

Re:Germany extends lifetime of all 3 remaining nuclear plants by LargoLasskhyfv on Tuesday October 18, 2022 @02:38AM (#33243748)
Did it ever occur to you that we actually could revert the atmospheric conditions we produced with those 'nukes' and attached 'atmospheric processors'?

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!

Re:Germany extends lifetime of all 3 remaining nuclear plants by LargoLasskhyfv on Tuesday October 18, 2022 @03:59AM (#33244306)
> Next you're going to tell me...

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.

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.

Re:Germany extends lifetime of all 3 remaining nuclear plants by atoav on Tuesday October 18, 2022 @02:51AM (#33243851)
Oh sure. The wave of deformed children that I grew up with in the shouthern German, southern Austrian area surely had nothing to do with this, pure coincidence. There are certain mushrooms that are still forbidden to eat.

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.

First, I am very sorry. That must have been unimaginably scary.

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 mostly agree, but I would also say the same thing about fossil fuels.

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?

Yeah most of this 'deformed children' stuff is also not really true. The reported facts about this are just not correct.

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.

The problem is that nuclear plants only need to fail once to have global catastrophic consequences. Chernobyl was so catastrophic that Gorbachev blamed the Soviet Union's collapse on it. Solar and other renewable energy sources can never even remotely approach this level of environmental risk.

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:

Candu's actually solve most of the problems the PWR constantly lies about. If people were proposing building those (and demonstrating that they weren't even more expensive) I don't see the issue.

They're hardly the super-100%-reliable baseload advertised, or anything approaching 'too cheap to meter' though.

Re:Germany extends lifetime of all 3 remaining nuclear plants by PM_me_your_math on Tuesday October 18, 2022 @09:14AM (#33246607)
Solar and wind can never even approach a fraction of the baseline power requirements either.

Of course, it takes a significant amount diesel fuel, energy, and mining to make EV related equipment, too.

Re:Germany extends lifetime of all 3 remaining nuclear plants by raxxorraxor on Tuesday October 18, 2022 @07:24AM (#33245669)
Problem is that one plant critically failing is enough to devastate large portions of land, especially in tightly packed Europe. And the fault in Fukushima was due to economic reasons, the risk of backup generators being flooded was known. These are realities that you won't ever address fully because it would make energy generation too expensive.

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.

See France and its maintenance issues with not just one but many of their power plants, accumulated over decades and now greatly contributing to the European energy problems. (https://www.economist.com/europe/2022/10/13/frances-nuclear-...)

Some issues I see are accountants, management, laziness, "somebody else's problem", etc. Those are businesses and they will try all the well-known ways to save money. Which the politicians will also encourage, because nuclear power will need to be justified continuously (like all other forms).

There also are water issues, not just river temperature (France, this summer), we also had a lot of European rivers with barely enough or not enough for most of the normal uses of those rivers this summer - and predictions are we'll have more such extremes. So, ensuring water supplies will be adequate at all times will become harder too, and much more expensive.

Not to mention that Russia - Rosatom - will again play a big role in Western European energy when it comes to nuclear. (https://www.investigate-europe.eu/en/2022/russias-multi-mill...)

Air plane and human space flight accidents are extremely rare but they still occur despite all the rules and regulations and the training and the many levels of precautions, but nuclear has to be even better.

Good thing that 1), nuclear fuel storage in europe tend to have almost decade long stockpiles, 2), there are plenty of alternative to Rosatom to buy nuclear fuel from, 3), nuclear fuel is fairly easy to import compared to massive amount of natural gas.

Sweden is only a stone throw away and they have nuclear fuel production that they sell as exports. They also acquired the design and patents to produce nuclear fuel that fit power plants from Rosatom. Those 20% of fuel that Russia sell is a solvable problem, but as with anything it would cost money, investments and a bit of time to ramp up production.

Re:Germany extends lifetime of all 3 remaining nuclear plants by panick21_ on Monday October 17, 2022 @08:22PM (#33241425)
And France having maintenance issues is in large part because of the anti-nuclear campaign that increasingly started to attempt to move away from nuclear. For a while even in France they basically just wanted to run the reactors out and switch to renewables.

So the politics goes like this, cause maintenance delay, condemn nuclear for maintenance delay. Seriously, these delays are being handled in a reasonable time-frames and most of the reactors will be back when they are really needed.

Consider that with the age of these reactors, wind-farms would have to be mostly rebuilt to a larger degree.

Also, if we actually made progress on technology then we could have had moved on to air-cooled designs but sadly we can't have nice things.

Just take a brief look at the list of nuclear accidents: https://en.wikipedia.org/wiki/Nuclear_and_radiation_accident...

There's various kinds of human errors (and humans will continue to make errors), equipment malfunctions, problems during equipment maintenance and so on.

Can you call "human incompetence" something to be planned for? Yes, sure, you have to plan for it. Can you plan it well enough so that it simply doesn't happen? Doesn't seem to have happened so far. Does it concern me too much? No. But do other people have to have the same risk tolerance? Also no. It's been proven that people are averse to rare-but-acute risks and can more easily accept frequent small risks (i.e. radiation and contamination from coal plants).

All that is to say that if people are concerned, it's on us to understand the reasons, not just shout into that void that "nuclear is SAFE!!!"

Re:Germany extends lifetime of all 3 remaining nuclear plants by karamanolev on Monday October 17, 2022 @06:20PM (#33240261)
Agreed. "A good reactor design" to that definition is enormously hard though - I'll be incredibly happy if that gets solved, hopefully with a modular "built in a factory" design that can be easily replicated and remain very safe.

No bad reactor designs get built or have been built in the West in many decades.

Better designs would have been here long ago if we actually had continued with this technology, but its not that current reactors are truly bad designs.

The problem with them is more that they don't fit into how energy markets and energy investments are made and have been made. That goes for both the US and Europe.
