U.S. investigates after lab improperly ships nuclear material
This is marking the latest safety lapse for Los Alamos National Laboratory as it faces growing criticism over its track record.
The National Nuclear Security Administration said it was informed by the lab in New Mexico that procedures were not followed when shipping small amounts of "special nuclear material" to facilities in California and South Carolina.
The material had been packaged for ground transport. But instead it was shipped via a commercial air cargo service, which isn't allowed under U.S. regulations.
Tests done on the shipments once they arrived at their destinations confirmed no contamination or loss of radioactive material, officials said.
But it comes as criticism has been intensifying over the history of safety lapses at Los Alamos as work ramps up to produce key components for the nation's nuclear weapons cache.
"This failure to follow established procedures is absolutely unacceptable," Frank Klotz, head of the National Nuclear Security Administration, said in a statement.
The agency oversees the lab and other facilities that make up the U.S. nuclear complex.
Contractors who manage the labs, production plants and waste repositories are required to rigorously adhere to what Klotz called the highest safety and security standards as part of their national security work. ■
