A yearlong investigation by government scientists has concluded that a major accident at a nuclear waste dump was caused by the wrong brand of cat litter.
The U.S. Department of Energy has released a 277-page report into an explosion that occurred on Feb. 14, 2014, at the Waste Isolation Pilot Plant in New Mexico. According to a summary of the report, the incident occurred when a single drum of nuclear waste, 68660, burst open.
As NPR reported shortly after the accident, cat litter was the chief suspect. The highly absorbent material is great at soaking up liquid nuclear waste, and it has been used for years in cleanup activities at the nation’s nuclear laboratories.
