> Partly I think nuclear triggers a cognitive bias where humans will tolerate ongoing low-level shittiness, but really struggle with large catastrophes, even if the catastrophe is far less damaging than the ongoing low-level damage. How come hydroelectric dams don't get treated this way? In 2019 a dam in Brazil had a catastrophic failure that cost the lives of 270 people. In 2019! In 1975 a dam failed in China and th…

Hydro disasters have been large, but are tangible/sensible, immediate, and resolve relatively quickly (days for rescue, months for recovery, possibly a few years for rebuilding). Banqiao is now home to 17 million people (after 40 years, largely achieved within a decade or so). Meantime, Chernobyl still hasn't seen complete containment (after 34 years), and Fukushima hasn't begun initial cleanup (after 9 years). The t…

That equals to slow but solid dissemination. Good luck trying to keep the migratory birds or fishes inside their boundaries at any time.

For the uninitiated, nuclear power is actually much, much safer than it was in the previous century, and fossil fuel power plants have killed exponentially more people through pollution than all nuclear power accidents combined – it's just not something that happens all at once so it doesn't seem like a big deal to most people. We will not be able to "defeat" climate change and keep this planet inhabitable for future…

We have Hyman G. Rickover, Admiral in the US Navy to thank for steering nuclear energy research away from thorium to uranium. He very much wanted the Navy to be in command of nuclear wessels carrying nuclear missiles. If I can remember correctly from research in US energy policy history in college, the US had sunk about 10 years into thorium reactor research when Hyman came along. Seems rather important to not ignore…

> the Navy has never had a nuclear accident. We've proven it's doable

Ehem... Where the USS Thresher and the USS Scorpion sailing under Mauritanian flag?

Nope. The US navy has never had a nuclear accident, they just lost two whole nuclear submarines that sank near Azores and Massachussets (but only 220 people were killed so it seems that the army forgot all about it yet).

The Navy has never admitted to a nuclear accident (other than radioactive coolant spills and the like, which it has admitted and which are nuclear accidents), but the US government has in other contexts kept nuclear accidents secret for decades after they happened, notionally for security reasons, so why wouldn't they do that with one occurring in the fleet?

Ongoing shittiness is predictable and easy to understand. We've survived so far, surely we can survive if it gets just a little worse. Big disasters are unpredictable and hard to understand. One of those could end the world at any time. AFAICT that's the whole reason people are more afraid of them.

> Big disasters are unpredictable and hard to understand. One of those could end the world at any time. In the context of nuclear reactors, Fukushima and Chernobyl are pretty much the worst case scenario. A large nuclear disaster is very disruptive to the immediate area but it would not "end the world" in any sense.

It's weird to see these two accidents grouped like that, given how they differed in severity.

Please stop with this. Nuclear is the only way to keep our current level of society. Our solar plants are going to lead to massive poisoned landfills due to their heavy metals. They are hard to recycle and so many are just dumping them. Modern nuclear can meet all our needs and stop global warming. If we pursued nuclear in the last century, we would be facing global warming now.

>Our solar plants are going to lead to massive poisoned landfills due to their heavy metals. "heavy metals" as in leaded solder, something that was banned in 2006?

> Our solar plants are going to lead to massive poisoned landfills due to their heavy metals.

How anybody would suspect that metals were so fully recyclable again and again? You just melt it in a mold, and voila!. Raw material. That was a lot of luck.

well,... unless they are radioactive metals of course. Then is more difficult.

Germany imports much of its electricity, which often isn’t generated from renewable resources.

Germany is a net energy exporter of 36.6 TWh last year. https://de.statista.com/statistik/daten/studie/153533/umfrag...

I can't read German so it's hard to consider this source. That said, it doesn't square with other sources I've seen that show Germany importing >50% of it's electricity, much of which is generated from fossil fuels:

Almost certainly nuclear accidents & other externalities were avoided. But would those have been more costly than the costs of fossil fuels (e.g. international conflicts, tens or hundreds of gigatonnes of CO2, many other contaminants, oil spills, etc.)?

We will never know. Stop acting like you know the wrong decision was made because the sports team you bet against made it.

Wind blows around the clock and solar runs most of the time we are awake. If renewables are super cheap but storage is not viable, can't we simply overbuild?

Wind is not as predictable as it seems, and most importantly, you don't get to control the production except for clamping down when you overproduce (this results in negative prices on the market and such). Then you have to add transfer issues, and you have situations where North Germany is exporting, while south Germany is importing, and there's a lot of fossil fuels burned just so you have capacity to keep the grid…

In my ideal future, demand doesn't need to be controlled that forcefully. Tank water heaters, electric cars, air conditioning, furnace fans, and dryers can all be networked and choose to operate when power is cheap. They can soak up spikes in production and back off in troughs. These things are also the vast majority of residential power (the only other heavy hitter is cooking)

Improved distance transmission would definitely be a big help.

Once I saw a TV show about the challenges of constructing a deposit for nuclear waste that is expected to operate for thousands of years. In this show, they mentioned that they did not want to use skulls to represent danger, because skulls are not seen as dangerous in some cultures (with "Dia de los muertos" as an specific example).

This was discussed extensively on a previous HN discussion: https://news.ycombinator.com/item?id=11851871

Major takeaway - you also can't say it's a place of death because an unscrupulous/desperate warlord might view symbols of death as ways to achieve power.

Another look at Fukushima can be that the incident was pure bad luck.

Can you elaborate? Do you mean having a Tsunami is pure bad luck in Japan? (With Tsunami actually beiing a japanese word...) I see your point though, one shouldnt go too much into 'what ifs', because all accidents are in a sense accidents/bad luck. But I still feel we can apply the what if on the outcome of the disasters, especially if it is that seasonal clear cut with high propability.

Related hypothetical: if a hydroelectricity dam failed when hit by an earthquake stronger than the one it was designed for, how much of a pass would we give Hydroelectricity?
