And I'll need to bookmark this just for the lack of points and the deafening silence, for the next time I see some grandstanding on HN about luddites being paranoid about nuclear waste and dumb one-off accidents.

It's an interesting puzzle, but not one for you and me to worry about. Vote Vault Tec.
Supposed people who otherwise seem very interested in nuclear energy discussed this as the interesting puzzle it is. How many would die? Apparently, all of them. Hence my comment, though its point seems to have escaped you. My concern isn't primarily nuclear radiation, my concern is the weakness of people who weren't even exposed to a lot of it.
99.9% of the time, none. They are stored in a bunker far from people.
A large part of why nuclear power is so expensive is because safety is considered so important. It's hard to get good numbers, but chances are more people have died constructing reactors and mining / refining ore etc. than from nuclear accidents. The difference is simply what people are less concerned when a heavy object falls on someone else.
In 2010 it was around 13,200 deaths/year from particulate emissions[1]. This is actually a big improvement, stricter regulations brought it down from 30,000 deaths/year in 2000 [2]. I should say that these numbers are surely not exact, there are big uncertainties both in the atmospheric modelling (how far the particles propagate) and in how dangerous the exposure is. But it's probably the right order of magnitude, there is a different report from the National Academy of Sciences in 2010 which arrived at a similar (but slightly lower) number [3].
The deaths from particulate emissions are not even necessarily the biggest problem with coal: if you price out the externalities, the cost of climate change (from CO2 emissions) is the biggest item [4].
The expense is already ungodly - "at least half a billion dollars" - one dirty bomb went off, and a whole lot more waiting.
What we should worry about is how critical systems go wrong in human hands - even in the stupidest of all possible ways - since there are more critical systems by the day. Genghis John's limit on maintenance and attention nears... yell it from the mountain tops!
Cornered rats fight hardest. Nuclear is already dead. No one can afford to build a plant, and voters are no longer ignorant enough to chip in. [0] The problem of course is that this particular industrial corpse will hang around stinking up the place for the rest of human existence. [1]
Well, this 'dead industry' still supplies 20% of the United States' electricity and 75% of France's electricity. Hell, France is even a net exporter of electricity...
Not a good example. France has an elite system making all political decisions, and that elite is formed partly by the nuclear industry. Also, its energy industry is on the brinks of collapse - turns out nuclear energy is expensive and the subventions already too high, at least for a country that sees itself as being in crisis. And there are a constant stream of accidents and safety issues in those nuclear plants.
Might be not dead over here, but it certainly isn't healthy.
I am overall a strong proponent of nuclear power -- but I gave you a point and bookmarked the article and this discussion under the "nuclear" tag for future reference.
I am a larger proponent of renewables in almost all forms, but they all share one really critical problem: they can't promise to scale to meet short-term spikes and drops in demand. For that, you need a fuel-based form of energy, and of those, nuclear is still the best we have.
(But demand for fuel energy can be reduced by rushing as quickly as possible to large-scale renewables and new energy storage technologies, and I hope that happens.)
Nuclear is not suited for balancing short-term spikes and drops in demand either. Fast balancing comes from spinning reserve, batteries (early stages still), reservoir-backed hydro power, and open cycle turbines. Take a look here at how little nuclear output ramps up or down over the course of a week, compared to every other source:
But nuclear generation could improve its economics and reduce the use of inefficient fossil fueled open-cycle turbines/spinning reserve if battery storage becomes more common and nuclear electricity recharges the batteries for meeting daily peaks.
What bothers me about this argument is that there's plenty of evidence that the overall public health damage from nuclear disasters is substantially less than from coal plants working as intended, and as Thaumaturgy pointed out, renewables will not be able to cover 100% of power production for many years. Absolutely we should use as much renewable energy as possible, but there has to be something to pick up the slack until the tech catches up, and between combustion and nuclear, nuclear is much safer even with regular disasters.
It seems like a statistical-awareness failure, like the people who won't fly because they're afraid of terrorists even though driving is far, far deadlier.
What argument did I make though? I just found it interesting that this genuinely curious story -- why did one of those 700 barrels react that way -- had literally zero comments after 5 hours on the front page, and was being snarky.
I mean, let's grant all that, let's say nuclear energy is 100000x more clean and safe and cheap than all the alternatives. Then why not discuss this curious thing about this most lovable of energy forms? Seriously, I thought the best stuff in science happens when someone goes "hey, this is interesting..."
If you love or even just like a thing, kick its tires!
Missing from this article is the most fascinating thing about this story- why someone thought it was a good idea to make the cat litter substitution that made this whole mess possible.
In Los Alamos, those charged with repackaging the waste were hearing a speech by an expert on the matter. The expert warned they should be using "INorganic cat litter", which they already were. What a member of the group heard was "AN organic cat litter".
The two look very different in print, but when spoken, they're often indistinguishable to a non-chemist. When the discussion made its way to memos and emails, the die was cast.
They may be indistinguishable but common sense still applies when asking for clarification. For example, I work with folks of a certain intellect where I have to ask very specific and pointed questions that do not contain substantial detail in each question in order to clarify something or to get an answer I need.
When that conversation happened, it should have ended with, "just to clarify, I should, or should not, use organic cat litter?" That would have cleared it up.
Furthermore, “It would have been much clearer if they had said an inorganic zeolite sorbent,” Hobbs says.
Wouldn't one argue that a better way to explain it would be to specify nonorganic kitty litter since that would clear up any confusion whether written or spoken?
Wouldn't one argue that a better way to explain it would be to specify nonorganic kitty litter since that would clear up any confusion whether written or spoken?
I don't know. Spoken, "a nonorganic" doesn't strike me as clearly better than "an inorganic" at differentiating from "an organic". Perhaps if you knew in advance the qualififications of the intended recipient, but in a safety specification like this, you may not know much about who will be (mis)interpreting the directive. Specifying "an inorganic zeolite sorbent" in the context of nuclear waste may make it more likely that someone who isn't sure about the meaning of one of those terms will seek clarification. By contrast, I'd worry that specifying "nonorganic kitty litter" would increase the chances that someone will just ignore the essential qualifier.
Worse, the word "organic" is overloaded, and means different things to the general public than to chemists. Juxtaposing the chemical meaning with the vernacular "kitty litter" increases the likelihood that someone will misinterpret, especially when "nonorganic" is more commonly associated with marketing and "inorganic" with chemistry. In cases like this where a seemingly innocuous detail is actually of critical importance, it needs to be emphasis and redundancy. The oft-quoted rule of "omit needless words" is more applicable to fiction and journalism than to safety specifications. For something as crucially important as this, I probably would suggest something like "a chemically inorganic sorbent, such as a 'kitty litter' made from zeolite clay".
Just such a linguistic difficulty seems to have played out with "flammable". I remember seeing until a few years back gasoline trucks labeled "INFLAMMABLE". No more.
How about not sending a non-expert to the grocery store with a post-it note for supplies when packaging radioactive material for long-term storage. Besides, "organic" when in the grocery store means something completely different any way -- ironically, the organic (wheat-based) product could easily be "non-organic" (meaning not certified to avoid certain pesticides, fertilizers, etc.), while the non-organic (clay-based) product might be labeled "organic" (meaning no pesticides).
Really, how about having a specific written signoff procedure in place, where all supplies must be checked before purchase by a trained expert who knows the difference between organic and inorganic / clay vs wheat, signed off in writing against a checklist developed by experts, then checked again by a separate trained expert when delivered with another signoff, then checked again by a third export when actually used.
We could call this process "receiving inspection" and have dedicated staff who perform this inspection who follow some type of written "work instruction" to inspect the receipt before approval.
> how about having a specific written signoff procedure in place, where all supplies must be checked before purchase by a trained expert who knows the difference between organic and inorganic / clay vs wheat, signed off in writing against a checklist developed by experts, then checked again by a separate trained expert when delivered with another signoff, then checked again by a third export when actually used.
Multiple inspection is a known failure point. A thinks any errors they make will be caught by B and C. B thinks A knows what s/he's doing, and thinks any errors that slip by B will be caught by C. C thinks A and B know what they're doing and so no errors will have reached C.
The boss that recruited A, B, and C to their position pulled the most accurate workers from the shop floor - because you need the inspectors to be better than the shop floor.
Thus quality of product supplied to inspection is reduced; the inspectors are now very busy; and that leads them to shift product through (someone else will catch it; someone else has already caught the problems).
What you need is to give an accurate instruction, and to give people to halt if they're unclear what's meant.
It seems so obvious to us, especially in hindsight. But I reject the notion that it's so obvious "anyone" would question something like this. If an expert says something directly and you are quite sure they said X and not Y, you are not likely to question it. You heard it from the horses mouth. I think that the speaker should try and emphasize INorganic or say it in a clearer way "non-organic" just to drive the point home.
>the speaker should try and emphasize INorganic or say it in a clearer way
The root problem here is that while the speaker may have been an expert in handling nuclear materials, they were not ALSO an expert in communication. The failure was the presumption that an expert can clearly communicate their domain knowledge across an expertise gap. Communication is a skill unto itself, one that often gets handwaved. People just assume they're good communicators because they can assemble a grammatically correct sentence. My wife is an editor. If I had a nickel for every time she's come home with a story about yet another coworker who claimed they "already edited their own paper and it just needs a quick look-over" and then handed her an incomprehensible mess, I'd have a lot of nickels.
How is "kitty litter" even a reasonable specification at all? We're dealing with nuclear waste but with less rigor than my car mechanic putting the right oil in my car?
Well, then, perhaps the key problem here is that the people charged with packaging nuclear waste were not experts in packaging nuclear waste.
For some reason I'm reminded of a recent visit to Takashimaya, a department store in Tokyo. After making a purchase, the checkout operator asked me (in perfectly clear English, for which she unnecessarily apologised) if I would like it wrapped. I said yes (this was a gift). I was directed down the hall to another desk staffed entirely by a team that had apparently been doing nothing for the last eighty years but perfect the art of swiftly and flawlessly packaging objects in attractive wrapping paper.
Thing is, no one I've met ever expects to spend eight decades of their life mastering wrapping paper and little else. In fact, many people might consider that a prison sentence and a slow death.
Some jobs are menial, unattractive, dead-end slots in machines designed to squeeze the youth from you. Motivation and morale matter, and maybe some people are cut out to find their niche early, but many are so painfully not. So what to do about that?
I didn't necessarily mean that the individual team members had all been there for eighty years. More that the team, as a general entity, had evidently persisted for a long time and built up enormous collective competence at a very specific task, but still in the context of an organic larger entity where their role was appreciated and understood.
I think it is a very unhealthy point of view to expect that a single individual perform a single mundane task repetitively and nothing else; sadly it is a common pathology of organisations that many such small roles are used to assemble a larger system.
I'm reminded of an extreme case of this every time I traverse a US airport, where there always appear to be far more staff than necessary (especially compared to the majority of airports I transit in Asia, Europe and Oceania) but none of them can assist you with any other part of the system they comprise, leading to many small systemic failures that leave inexperienced travellers confused, late, lost, even detained; and occasional large systemic failures like those recently in the press.
This is also how many organisations develop software, particularly enterprises & government, and is a partial explanation for the resulting shitshow.
As for what to do about lost potential, I think the answer is the same it ever was: universal education, universal healthcare, eradication of poverty, eradication of conflict, and this a great way to annoy the Randites.
Oh, fair enough. Even so, I don't think that sort of thing (refined collective memory, among simple tasks) happens, except in select societies and subcultures.
Large retail operations in the United States do well at supply chain efficiency, but the last mile is still pretty desolate and miserable. There are still signs of life in smaller or more careful operations, but most corporate store fronts are filled with hateful misery, and I remember being a part of it and feeling all the reasons to hate it, for several years of summer jobs.
I didn't even catch the taste of a vaguely desirable job until my late twenties, and I think I'd choose death over a backslide. Having to face radiation, on top of surrendering 40 hours of my waking life, all while watchng how others live across the internet and on TV, I'm sometimes baffled by the safety of anything at all.
It does seem to be an emergent property of some cultures. My wife, being of Chinese origins, observes frequently on the east Asian preference for collective thought and action, usually contrasting this with her experiences as a senior manager in a western hierarchy.
There are downsides to groupthink, too, though; as a perhaps extreme example, the Fukushima disaster has been partly blamed on the resulting aversion to questioning a status quo.
Here in Australia, and also in the US, I think some managers are not happy until they've reduced every job to a process job. There are still companies where this is not the case, and if you cannot find one, it is also easier here to start your own.
> I'm reminded of an extreme case of this every time I traverse a US airport, where there always appear to be far more staff than necessary (especially compared to the majority of airports I transit in Asia, Europe and Oceania) but none of them can assist you with any other part of the system they comprise
I'm so glad to see someone else mention that! It always makes me think that the US is a communist state in disguise when I see all the unnecessary people in US airports.
This kind of packaging is very common in Brazil. People here certainly don't spend 80 years learning that. Instead, some days watching someone doing it is probably ok.
It's very easy to fall into this mistake because language-wise they're both sorta correct. Using a,an,in etc to prefix a word X to indicate the lack of X is called Alpha Privative which dates back to the ancient Greeks but was later adopted by other cultures. So "inorganic" and "anorganic" might be both correct when expressing the lack of organic material, although as a word "inorganic" is the one that caught up and using "anorganic" - especially in an English speaking context - can lead to misinterpretations like that one.
All they had to say is "use this SKU kitty litter ONLY, nothing else. Here's the link. Do not buy anything else or you can cause a massive disaster. Here's a picture of the bag. Any deviation from this must be approved by a domain expert."
In other words, when failure is not an option you have to engineer out failure vectors. This was stupid simple to prevent. I don't see it as a failure of the workers, they don't know any better.
As an example, in aerospace you vet and qualify every single material through Material's Engineers. Only materials that have been approved for a particular use are designed into an assembly. It would be inconceivable for an assembly technician to order an alternative adhesive from a random catalog. This is proper engineering.
It sounds like the folks running the nuclear waste installation had no idea how to manage a mission critical process.
The whole story can be shortened down to two sentences:
> Investigators traced a series of internal communications in which the specifications for “kitty litter/zeolite clay” were transformed into “kitty litter (clay),” the report says. Combined with inadequate technical review, this resulted in LANL workers filling waste containers with a mixture of nitrate salts and sWheat Scoop, a cat litter that is 100% wheat, according to its manufacturer.
Removing "zeolite" is consistent with just about every popular piece of advice on how to write:
1. Don't use jargon.
2. Remove unnecessary words.
3. Write a third grade level.
So someone comes along and sees the phrase "kitty litter/zeolite clay" and decides that its author does not know how to write based on its author not following the rules and applies syntactic rules without understanding the semantics (in this case the semantics of nuclear chemistry).
Item 1 is especially bad because the whole intent of jargon is to be clear to readers of the same or similar technical level. There's an engineer at work who occasionally tries to harangue me into applying these rules to technical documents and emails to other engineers because she thinks they're "unclear." They're not unclear, she just doesn't have the technical aptitude in my field to read them.
Agreed. As anyone exposed to the media in general knows, we do have a very strong preference for "clear but mistaken" and "false as stated" utterances. Any nuance is quickly labeled a "mixed message" and eliminated - as if the universe never contained a mix of anything that one might want to talk about.
Traditionally, it has been exact. Physicists are ordinary people and use ordinary language to talk to other physicists. It became inexact when the low bidder bought wheat waste and called it "kitty litter" and ignored "(clay)".
I'm not disagreeing. However, I would not be surprised if the price ratios at retail differ from those at bulk wholesale and at moments in the spot market. My suspicion is based on some experience with the spot market for fill dirt and the evidence here that kitty litter made from wheat byproducts was supplied by the low cost bidder and the premise that the low cost bidder was a rational economic actor.
I could believe that Swheat Scoop was the low bidder once someone in the purchasing chain had ruled out the clay options, but I'd be very surprised if any of the organic materials could compete with clay.
With fill dirt the way the market works is if some Owner has an unbalanced site where there's more cut than fill, then the fill dirt is a bargain because the Owner would otherwise have to pay to haul the dirt away. On the other hand, if tho Owner needing fill dirt heads down to his local dirt mine, the proprietor can stick to their asking price because the dirt in the dirt mine doesn't go bad.
My suspicion is that someone was sitting on a big pile of wheat waste, which unlike fill dirt is organic and probably goes bad and probably needs to be moved off the wheat processing lot for next week/month/year's wheat harvest...and the wheat waste (unlike fill dirt) probably needs to be disposed of properly in a sanitary landfill and that's some more expense.
I mean at some point, someone is probably paying to have the wheat waste hauled away, whereas zeolite and other clay minerals are typically mined deliberately.
My suspicion is based on some experience with the spot market for fill dirt and the evidence here that kitty litter made from wheat byproducts was supplied by the low cost bidder and the premise that the low cost bidder was a rational economic actor.
Your suspicion sounds plausible, but looks to be directly contradicted by the Department of Energy's post-investigation report. To the contrary of this being a decision made by the low cost bidder, the problems with the process started with a mistake in the specification that was produced by Los Alamos National Security LLC, the private company specifies the proper operating procedures at the national lab:
"When LANS began using this procedure to process nitrate salt wastes in September 2011, it did not perform a USQD [Undetermined Safety Questions Determination], as required, because the change from inorganic to organic absorbent was incorrectly determined to be an administrative (minor) change."
"In one particular instance, a conduct-of-operations SME [subject matter expert], working outside of his/her area of responsibility, added new text to DOP-0233 that included using organic kitty litter as an absorbent, as opposed to the inorganic zeolite material discussed previously in technical team meetings."
"In the previous example, the SME's addition of the text to DOP-0233, Section 10.6, which included the word 'organic', was submitted informally as a 'minor' comment, rather than an 'essential' comment that would have required explicit concurrence from the entire SME team."
Unless the report is wrong, or unless the SME who made the change was actually working in deep cover for a kitty litter producer with a surplus of wheat, this looks to be an error of knowledge and process, not a cost-cutting measure by a low bidder.
It appears that organic was added alongside inorganic. Which means that the low bid was for organic litter. Having written specs, alternatives to established specifications are often proposed by vendors.
Normally for government specifications, opportunities to enjoy pitches by vendors to have their products added to the specification are not allowed due to the potential appearance of a conflict of interest. On the other hand, an LLC might not have quite as rigid a protocol...and establishing an LLC might even be done to avoid having rigid protocols around bidding and vendors.
Now I could be completely off base and a low level employee went cowboy all on their own due to some previous knowledge of organic kitty liter and the economics of its bulk availability. The center of the distribution when specs get changed to allow an alternative technology is more commonly customer eduction by vendors.
Writing "kitty litter/zeolite clay" certainly was bad style — it left ambiguous what the relation between "kitty litter" and "zeolite clay" is, which invited the editor to assume that they were synonyms and to just pick one.
Remember, kids, if you receive a sentence that's ambiguous, you can't edit it to make it less ambiguous if you don't have an extrinsic reason to know what was meant. Blindly editing can only destroy information, not create it (also known as the autocorrect problem).
Should have been written as 'Zeolite Clay conforming to Specification 239.11'
Specifying a generic or branded product for an off label use is just a bad bad idea. Because the manufacturer of kitty litter can't be counted to control for any properties other than those reflecting use in a cat box. Fatcat(tm) Unscented Kitty Litter might be fine until one batch shows up that's 95% zeolite clay / 5% sawdust.
This is exactly key. In GMP pharmaceutical manufacturing, you have to spell EVERYTHING out - chemical compound, the manufacturer, the batch. I'm quite surprised that the nuclear industry doesn't follow the same level of rigor - there ought to have been some sort of SOP document for which sorbents to mix with radioactive nitrates.
Which is one of the reasons government purchasing specifications are famously absurdly complicated.
First, if you really need zeolite clay you can't use the shortcut term since someone will complain to the IG that you stupidly overpaid and wasted the taxpayer's money.
Second, relatedly, some vendor will sue because you specified a "hammer" but didn't specify the material, thus overlooking their cheap plastic hammer.
And as a result we end up with the $600 toilet seat.
It's a wonderful example why people should be educated far beyond their pay grade. Any mildly trained chemist would know that combining nitric acid and organic material is setting oneself up for an explosion. They should have reached for the Andon cord right tbere.
Confusion about choosing the chemically appropriate kitty litter comes up more frequently than one might expect. While a zeolite clay based litter is the best choice for nuclear waste, the message here isn't that it's the best choice for all purposes. It turns out that different applications require different kitty litters!
Oyster mushrooms can be grown on lots of "plant based" substrates. One easily available substrate is kitty litter made from recycled newspaper, such as the "Yesterday's News" brand. If you to use a zeolite based litter here (even if it had organic certifications) your mushrooms would grow poorly if at all: http://www.namyco.org/docs/grow_oyster_mushrooms_on_kitty_li.... But for bonsai, both clay and recycled newspaper would be a disaster. Here, you need a litter made from "diatomaceous earth", such as Tesco's "Low Dust Lightweight Catlitter": http://www.bonsai4me.com/Basics/Basicscatlitter.htm. Tomato seedlings have about the same requirements as bonsai: http://www.tomatoville.com/showthread.php?t=22329.
I mention these partly as a joke, but there actually is a deep commonality here. All of these are real world situations where the specific type of cat litter used has implications, and in all of them, despite the authors' strong desire for precision and clarity, you find forums full of people who take the "shortcut" of using the wrong type of cat litter and then complaining that it doesn't work. I'm not sure what the solution is, but in the future it sure would be great if we could troubleshoot the instructions in the mushroom, tomato and bonsai communities rather than jumping straight to nuclear waste disposal.
Does anyone have examples of other communities making odd uses of specific types of kitty litter?
I've heard similar claims of that "magic sand" or whatever it's called when you mix fine sand and silicone oil. The results seem to speak reasonably well of the method, if AvE's attempt [1] is any guide.
Kind of funny that I have actually had the same problem. I collect succulent plants and when you get to a certain point you need to start making your own soil mix.
One of the best ways for that is to use soil and hot-fired clay / diatomaceous earth. Which is not really easy to find as a product. Funny enough cat litter can be just that. However, there are many cat litters out there which are made from a wide variety of things. So it's really difficult to eek out the right stuff.
Like the article says it can be organic material, or it can be clay that turns to mush when it gets wet. There are other materials out there though, like Turface, which is always high fired clay, or oil-dry materials from auto supply stores, which varies a lot like the cat litter.
Either way it kind of seems insane that they are acquiring this material instead of finding a direct and reliable source for the exact material they want.
"An October 2014 report from the Department of Energy’s Office of Inspector General points to a change in the packaging procedure at LANL that specified organic cat litter, when an inorganic sorbent was likely intended. Investigators traced a series of internal communications in which the specifications for “kitty litter/zeolite clay” were transformed into “kitty litter (clay),” the report says.
