The Department of Energy’s Idaho Cleanup Project (ICP) has improved transuranic waste operations to address aging waste containers being stored at the Advanced Mixed Waste Treatment Project (AMWTP) at the Idaho National Laboratory Site, the DOE’s Office of Environmental Management announced on December 10.

The Idaho National Laboratory is moving closer toward closing its largest building—which, at more than 316,000 square feet, could comfortably house a modern U.S. aircraft carrier, according to the Department of Energy.
