Organic Cat Litter May Have Caused Nuclear Waste Accident 174

Posted by samzenpus from the that's-a-bad-kitty dept.
mdsolar (1045926) writes in with a story about how important buying the right kind of kitty litter can be. "In February, a 55-gallon drum of radioactive waste burst open inside America's only nuclear dump, in New Mexico. Now investigators believe the cause may have been a pet store purchase gone bad. 'It was the wrong kitty litter,' says James Conca, a geochemist in Richland, Wash., who has spent decades in the nuclear waste business. It turns out there's more to cat litter than you think. It can soak up urine, but it's just as good at absorbing radioactive material. 'It actually works well both in the home litter box as well as the radiochemistry laboratory,' says Conca, who is not directly involved in the current investigation. Cat litter has been used for years to dispose of nuclear waste. Dump it into a drum of sludge and it will stabilize volatile radioactive chemicals. The litter prevents it from reacting with the environment. And this is what contractors at Los Alamos National Laboratory were doing as they packed Cold War-era waste for shipment to the dump. But at some point, they decided to make a switch, from clay to organic. 'Now that might sound nice, you're trying to be green and all that, but the organic kitty litters are organic,' says Conca. Organic litter is made of plant material, which is full of chemical compounds that can react with the nuclear waste. 'They actually are just fuel, and so they're the wrong thing to add,' he says. Investigators now believe the litter and waste caused the drum to slowly heat up 'sort of like a slow burn charcoal briquette instead of an actual bomb.' After it arrived at the dump, it burst."

    It should be noted that this waste is from cold war era defense programs, and not used commercial nuclear fuel which is much easier to handle and store. It should also be noted that although the writers make every effort to call the WIPP a "dump" in order to conjure up images of a simple landfill, it is actually an underground geological (saltbed) monitored storage facility created for storage of radioactive waste.

    Unlike chemical from many industries that are dumped in many places with much less control, this is an example of quick recognition and response to a problem. Cold war nuclear waste comes in all kinds of nasty liquid, solid, and semi-solid forms and will continue to bring challenges as the slow cleanup slog continues.

    Of course, this slashdot submission is one of an ongoing number of agenda driven submissions that intends to obfuscate the challenges of cold ware era defense program neglect with commercial nuclear power. Fortunately, most slashdot readers pick up on the obvious.

      It is absolutely an agenda submission. It even looks to me like it's trying to be critical of the organic movement. I'll reserve my opinion of that kind of thing, but in this case, "organic" means what it actually means, not the hippie non-term it has become. I'd rather they say it was because they switched from clay-based to plant-based kitty litter. The risks of this should have been obvious to someone working with radioactive disposal.

        It's considered a nuisance in this context because it's largely inert (and often formulated for absorbency and clumping, so people are advised not to flush it): Once used, the clay just adds weight and bulk to the solid waste stream and won't be going anywhere in approximately geologic time. Aside from very modest risks from mineral dusts, it's harmless enough; but it's not wildly efficient to landfill something that's mostly clay just to deal with animal feces that would degrade in a few weeks to months under proper conditions.

    Just because a material has a everyday name, it doesn't mean that the original specification didn't have a chemical/mechanical/biological/radiological/whatever reason for specifying it.

    If all the material property requirements were met with a commonly available product that didn't require an expensive supply chain, then that's great.

    HOWEVER...

    I suspect that originally somewhere in the nuclear disposal system, a group identified the need, a solution was found and a materiel was specified. Along the line or through the years, the REASON for that specification was lost to the end of the purchasing chain and the poor sod who orders the stuff was given a directive to "buy sustainably" and substituted the new material without being aware of the original intent.

    That person probably wasn't even been aware of the use of the material - they may have though it was used in the kennels for the guard dogs. It's a nuclear material disposal site. Need to know is important. (1) The suppler wouldn't have known, either.

    There's lots of complaints of expensive procedures and materials(2), but this is a perfect example of the need for a formal supply chain system with provable provenance. You may BUY a commonly available kitty litter to fulfill the order, but what arrives in the sacks will have to match the specification sheet.

    1. Yes, this is irony. The accident may have been prevented if the purchasing officer knew what it was for. Then again, maybe not.

    2. Ferrous hammers are a bad idea around strong magnetic fields. If you're in a lab with a MRI or similar and lots of delicate equipment, a hammer to undo the dog on a vacuum chamber had better be a very special hammer. The kind that you can buy today for less than a hundred bucks, but in the 60's had to be engineered from scratch. Thank someone else's R&D for the fact you can buy a (nearly) chemically inert, non-ferrous, non-sparking hammer for a pittance.
