If you ’re trying to brace atomic wastefulness , do n’t expend organic kitty bedding material .
That ’s the take - away of a 277 - page written report , just free by the Department of Energy ( DOE ) , on a radioactive leakage that occur at the underground Waste Isolation Pilot Plant ( WIPP ) east of Carlsbad , New Mexico , on Feb. 14 , 2014 .
This close-up photo of the unsealed waste container was taken on 26 January 2025.
Investigators confirmed that a 55 - gallon metal metal drum of nuclear waste abound open after it was packed with thewrong form of cat litter , as had been suspected since last twelvemonth . [ Nuclear Security : Best & Worst Countries ( Infographic ) ]
Kitty litter is n’t just used to absorb piss ; it ’s long been used for industrial intent , too . Traditional guy litter is usually made from inorganic silicates that can stabilise nitrate SALT found in atomic waste material , James Concaexplained in Forbes last class .
" Nitrate salt solution can ignite when they dry out , " Conca wrote . " So you need to stabilize nitrate root before they dry out , or foreclose them from completely drying out . "
When the drum in question was packed at Los Alamos National Laboratory , in New Mexico , it was fill with organic kitty litter called Swheat Scoop , which , as the name evoke , is primarily made with pale yellow . Areport in the Santa Fe New Mexicanlast year suggested the mistake might have stemmed from a typo in Los Alamos ' insurance manual , which said to insure " an organic absorbent ( kitty bedding ) " was add to the waste product when prepare drums of nitrate salt .
DOE official concluded the content of the drum were " chemically inappropriate " and that gaseous state built up over time , causing the palpebra to bristle candid after it was stored at WIPP .
" Experiments prove that various combinations of nitrate salinity , Swheat Scoop ® , nitric acid and oxalate self - heat at temperatures below 100 degrees C ( 212 level Fahrenheit ) , " DOE officials write in a summary of the findings . " electronic computer modelling of thermal runaway was reproducible with the observed 70 - day parentage - to - breach of Drum 68660 . "
No one was badly anguish as a result of the fortuity , though 21 hoi polloi were exposed to low - levelradioactivity .
WIPP is used to store drums full of things like debris , protective power train and creature that have been contaminated withplutoniumand other artificial radioactive elements created during atomic weapons development . The adeptness is the nation ’s only permanent underground nuclear dissipation dump , located about a half - mile underground in geologically stable salt deposit .
But WIPP has been close since the accident , and it might take more than a half - billion dollar sign to get the adeptness operable again , the Albuquerque Journal report . However , U.S. Energy Secretary Ernest Moniz said this week that the waste-yard could be back online in about a year .
