ALBUQUERQUE, N.M. (AP) — The federal government has issued a pair of preliminary notices of violation against two contractors after a radiation leak forced the shutdown of the nation's only underground nuclear waste repository.
The U.S. Department of Energy said Friday the notices mark the completion of investigations into the 2014 disaster as well as the enforcement process against the managers of Los Alamos National Laboratory and the Waste Isolation Pilot Plant.
The notices cover worker safety violations at the southern New Mexico repository as well as violations stemming from the handling of waste at the lab.
The contractors did not immediately respond to requests for comment.
Investigators determined the radiation leak was caused by waste that had been inappropriately packed at the lab then shipped to the repository for storage.
