“Unfortunately, workers at Los Alamos National Laboratory, also in New Mexico, apparently switched from inorganic clay litter to organic litter. According to the report, workers put the brand “Swheat Scoop” inside drum 68660.
“Experiments showed that various combinations of nitrate salt, Swheat Scoop®, nitric acid, and oxalate self-heat at temperatures below 100°C. Computer modeling of thermal runaway was consistent with the observed 70-day birth-to-breach of Drum 68660,” the summary of the report concluded.”
