After initial runs using a mix of radiological waste and nonradioactive simulant, the Integrated Waste Treatment Unit (IWTU) at the Idaho National Laboratory site has progressed to treating sodium-bearing waste entirely, the Department of Energy’s Office of Environmental Management (DOE-EM) announced on May 22.

The United States and Canada will cooperate on spent nuclear fuel management under a statement of intent (SOI) signed between the U.S. Department of Energy and the Nuclear Waste Management Organization, the nonprofit responsible for the management of Canada’s commercial spent fuel.

Since the launch of operations just over a month ago, the Integrated Waste Treatment Unit (IWTU) at Idaho National Laboratory has increased sodium-bearing waste treatment fivefold. This activity is a vital step in removing the remaining liquid waste from nearby underground tanks at the site and protecting the underlying Snake River Plain Aquifer.

After nearly three years of discussions and more than 60 mediation sessions, the Department of Energy, Washington State Department of Ecology, and the Environmental Protection Agency announced that they have reached a conceptual agreement on revising plans for managing millions of gallons of waste stored in tanks at the Hanford Site near Richland, Wash.

The Department of Energy’s Waste Isolation Pilot Plant (WIPP) recently marked a milestone after its drivers exceeded 16 million safe miles without a serious accident or injury—equivalent to 33 round trips to the moon or more than 642 trips around the world, the DOE’s Office of Environmental Management announced.

The Department of Energy’s Office of Environmental Management (EM) has made great progress in accomplishing its cleanup of legacy radioactive waste but has yet to tackle its most challenging tasks, including the treatment of liquid tank waste at the Hanford, Idaho, and Savannah River sites. That was the consensus of the DOE-EM officials who took part in a panel session of the 2023 Waste Management Symposia, held February 26–March 2 in Phoenix, Ariz.

While still lacking a deep geological repository for the permanent disposal of its commercial used nuclear fuel and high-level radioactive waste, the United States does have regulatory standards for geological nuclear waste disposal.
Having been written nearly 40 years ago, however, those standards are outmoded and lack transparency, according to a special committee of the American Nuclear Society, which has released draft recommendations on revising public health and safety standards for future geological repository projects in the United States.

The Defense Waste Processing Facility (DWPF) at the Department of Energy’s Savannah River Site (SRS) in South Carolina has resumed operations after a completing a processing improvement that the DOE said will enable safer operations and more efficient vitrification of radioactive waste.
