I agree and I think the damage to humanity that the anti-nuclear movement has done is incalculable. So many years of progress have been missed out on... and while some of it was due to greed (fossil fuel industry funding), most of it was just misplaced fear, whether propaganda induced or from an inability to see the full picture.

The anti-nuclear movement is also still alive and doing well but at this point it's like arguing over spilled milk, the damage is mostly done and a lot of is irreversible. We can try to salvage nuclear but we've already regressed to further impure sources in some countries so progress seems unlikely.

Fear of nuclear is distrust in the government. I believe in nuclear as a technology, and I believe in mankind's ability to perform science and engineering tasks. I don't have a lot of faith in the role of the government in properly and adequately regulating a booming nuclear industry.

>Fear of nuclear is distrust in the government.

Is it though? The US Navy has a pretty impressive nuclear safety record for the number of reactors they have in service.

To flip it, would you have more trust in a private company with nuclear safety? If the same decisions being made that allows PG&E to cut their funding for maintenance that allows their lines to be the cause of California's forest fires, why would we trust they would pay for the upkeep on a nuclear reactor?

Look here’s what you want to consider. The waste needs to be stored safely and responsibly for not a decade, not a century but for thousands of years. We can’t manage shit that needs a few years of care unless it continues to make profits right now. It’s a fucking joke. So your local government is recommending a nuclear waste dump, as mine is. Here’s basic maths to know if your getting screwed or if they’ll be doing…

> Look here’s what you want to consider. The waste needs to be stored safely and responsibly for not a decade, not a century but for thousands of years.

I find that people making this argument always always fail to engage with at least three important considerations.

1) As a consequence of how physics works, the more dangerous a radioisotope, the shorter the period for which it is dangerous. The most radioactive substances decay in years or decades, not millennia. Anti-nuclear activists routinely engage in a form of equivocation in which they juxtapose dangerous but short lived substances (e.g. Strontium-90 has a half life of a few decades) with long-lived but low-danger substances like Uranium (with a half life of billions of years), pretending that every form of radioactive waste is as dangerous as the most dangerous form for as long as the longest-lived form survives.

2) Anti-nuclear activists routinely ignore the possibility of reprocessing nuclear waste into more nuclear fuel. They pretend that our only option is to store this fuel indefinitely. They also use this epistemic void where reprocessing should be to argue that we don't have enough nuclear fuel on Earth to sustain civilization. We do, and we do by several orders of magnitude if we remember that nuclear "waste" can be turned into new fuel.

3) Anti-nuclear activists routinely ignore how modern civilization produces non-nuclear waste products that prompt similar concerns over waste safety. (See, for example, the famous Love Canal incident.) By fixating on nuclear waste and ignoring other industrial byproducts that are at least equally as harmful, anti-nuclear activists reveal themselves as being motivated by some kind of emotional or ideological opposition to "the atom" in particular instead of, as they claim, an altruistic concern for the safety of humanity in general.

All in all, these people are Luddites, and they've set back the progress of carbon free energy by almost a century. We need to ignore people afraid of nuclear power in the same way that we ignore people who worry in public about the power of witches and Mercury in retrograde.

Your hot spoon is in fact radioactive, emitting thermal radiation. Thermal radiation doesn't make things it hits radioactive. Neither does your microwave oven or even gamma radiation. Radioactivity can be induced in things by neutron radiation, but not EM radiation. It is safe to eat food which has been irradiated with gamma radiation, and chances are you have many times before (it is fairly common for dried spices a…

Things that emit thermal radiation are not radioactive. An easy way to conceptualize it for stuff here on Earth is that radioactivity involves stuff flying out of the nucleus of an atom, while other forms of radiation do not.

Thermal radiation is in fact emitted from the nucleus of atoms; all matter emits black body radiation. The reason hot things generally aren't considered radioactive is because that would pull literally all matter into the discussion.

But that wasn't the point being made here. The point being made with the hot spoon example is that EM radiation doesn't make other things radioactive (except insofar as it heats things up). This is equally true of gamma radiation as thermal radiation. Thermal radiation and gamma radiation can both cause harm directly, but neither will make other things radioactive.

That's why it's completely safe to eat food that was sterilized with gamma radiation intense enough to kill you outright.

Once waste has made it to dry cask storage, it's not much of a problem. But there are still too many spent fuel rods in cooling pools at power stations. That stuff was supposed to go to Yucca Mountain, but for political reasons, that didn't happen.

Until it explodes because it was filled with organic instead of clay kitty litter and costs $500 million to 2 billion and two years to clean up (this happened at WIPP in 2014)

https://theecologist.org/2016/sep/20/wipp-nuclear-waste-acci...

It seems that nobody can safely deal with nuclear material cost effectively.

From the article:

Worse still, mismanagement of the clean-up has involved poor safety practices. Last year, the DOE's Independent Office of Enterprise Assessments released a report that found that WIPP clean-up operations were being rushed to meet the scheduled reopening date and that this pressure was contributing to poor safety practices.

The report states: "The EA analysis considered operational events and reviews conducted during May 2014 through May 2015 and identified a significant negative trend in performance of work. During this period, strong and unrealistic schedule pressures on the workforce contributed to poor safety performance and incidents during that time are indicators of the potential for a future serious safety incident."

The report points to "serious issues in conduct of operations, job hazard analysis, and safety basis." Specific problems identified in the report include:

workers incorrectly changing filters resulting in five safety violations;

waste oil left underground for an extended period despite a renewed emphasis on combustible load reduction;

fire water lines inadequately protected against freezing;

inadequate processes leading a small fire underground, followed by the failure of workers and their supervisor to report the fire;

an operator improperly leaving a trainee to operate a waste hoist, the hoist being improperly used, tripping a safety relay and shutting down the hoist for hours;

an engineer violating two safety postings to remove a waste hoist safety guard;

workers removing a grating to an underground tank and not posting a barricade, causing a fall hazard;

a backlog of hundreds of preventive maintenance items; and

failing to properly track overtime such that "personnel may be working past the point of safety".

While these are reasons to be suspicious, they do not counter a single point she made in her article. Her logic and her facts were solid. If they're not, I'd love to see a take down of that. But I see no problem with anything she wrote, I remain convinced nuclear is the only rational energy source left, and all this fear mongering about nuclear is causing us to slowly kill ourselves.

> I also learned that batteries cannot be recycled.

That seems factually incorrect, and the anti-renewables paragraph was the thing that jumped out at me most, though the author claims not "to say that we should abandon renewables altogether, but to illustrate that all energy generation carries an environmental cost, and no solution is perfect."

We are talking about 32 countries with civilian nuclear power operating for several decades. With oversight by an international body that tracks every bit of nuclear material. Using processes that differ from what was done at Hanford, producing waste different from Hanford. That has been working well, stored well and safely without issue. The military didn't start from that position, it started from "Joe just throw t…

A minuscule amount of tritium, dumped into an ocean that has billions of tons of uranium dissolved in it. This Fukushima water issue is a perfect example of people letting emotions overrule rational thought.

A destroyed dam is temporary damage. There are going to be eventually gravely ill Russian soldiers last year because they ignored the warnings in the Chernobyl exclusion area. https://www.nytimes.com/2022/04/08/world/europe/ukraine-cher... > In a particularly ill-advised action, a Russian soldier from a chemical, biological and nuclear protection unit picked up a source of cobalt-60 at one waste storage site with his…

"Temporary damage", really? The deaths of those downstream from a burst dam are no less permanent than the death of an irradiated Russian. And there are a lot more of the former than the latter.

Yes. Just like the black death was temporary damage.

Fission waste is truly long term. Just like desertification.

I've worked in the energy industry. There is complete capture there. When PG&E is the "bad guy" it's because the government needs them to be. ERCOT works the same way (though is better).

If the government wanted PG&E to properly fund their line maintenance, PG&E would properly fund their line maintenance.

Can you share the details about renewables being cost competitive with oil?

chat.openai.com claims it is true, albeit without specific sources: Yes, there is a significant amount of data and research that supports the increasing competitiveness of renewable energy compared to oil. Here are a few examples: The International Energy Agency (IEA) reported that in 2020, the average global cost of producing electricity from solar photovoltaic (PV) systems was lower than the cost of producing elect…

Out of curiosity, I asked "How can we fix the climate crisis? Be specific."

Obviously we shouldn't rely on ChatGPT for our answers to life, but it's not a terrible list. Except for the absolute lack of any mention of nuclear, which I think fairly reflects the zeitgeist but not the real science.

Here's what it said:

1. Switch to Renewable Energy Sources: We should phase out the use of fossil fuels and switch to renewable energy sources, such as wind, solar, geothermal, and hydropower. This would reduce carbon dioxide emissions and other pollutants from burning fossil fuels.

2. Increase Energy Efficiency: We should invest in technologies and practices that reduce energy consumption, such as LED lighting, efficient heating and cooling systems, and better insulation.

3. Plant Trees and Protect Forests: Trees absorb carbon dioxide, so planting more of them can help reduce the amount of carbon dioxide in the atmosphere. We should also protect existing forests and prevent deforestation.

4. Reduce Food Waste: Food waste is a major contributor to climate change, as it releases methane and other greenhouse gases when it decomposes. We should reduce food waste and increase food recycling.

5. Reduce Meat Consumption: Animal agriculture is a major source of carbon dioxide and other air pollutants, so reducing meat consumption can help reduce emissions. We should also promote plant-based diets.

6. Improve Transportation: We should invest in public transportation, electric vehicles, and other low-emission transportation options. This would reduce emissions from cars and other vehicles.

7. Educate and Advocate: We must educate people about the causes and consequences of climate change, and advocate for public policies that can help mitigate climate change.
