The final drums of old transuranic waste stored at Oak Ridge National Laboratory have been prepared for disposal.

The U.S. Department of Energy’s Oak Ridge Office of Environmental Management reported Tuesday that it had recently completed installing vents and sample ports in the final drums of the legacy transuranic waste stored at ORNL. The decade-long effort ensures that the drums do not contain any hazardous gases that could cause rapid combustion.

The ventilated unit where the drums were vented is closed and explosion-proof, DOE said. It is capable of withstanding a combustion event while keeping workers and ORNL, the nation’s largest multi-program national laboratory, safe, DOE said.

“Venting and sampling these drums is an essential part of the waste disposal process,” ORNL Portfolio Federal Project Director Bill McMillan said. “Now that we can ensure the safety of each drum, they are ready for transport to the Transuranic Waste Processing Center for processing and subsequent shipment to a permanent disposal facility away from Oak Ridge.” [Read more…]
