Littered with errors

By Michael Banks

Photograph of Swheat Scoop cat litter (CC-BY-SA Ryan Forsythe)Cat litter and radioactive waste – not a combination you would normally expect to come across (although some cat owners may disagree).

But a report by the US Department of Energy has squarely blamed kitty litter for the explosion of a single drum of nuclear waste – dubbed “68660” – that burst open at the Waste Isolation Pilot Plant (WIPP) in New Mexico in February 2014.

A year-long investigation by a nine-member panel – led by David Wilson of the Savannah River National Laboratory – has concluded that the incident was caused by the use of the wrong brand of feline litter.

As cat litter is highly absorbent, for years it has been used to help keep nuclear waste contained. Indeed, each barrel of waste at the WIPP is filled with about 26 kg of the stuff.
