In this week’s “EM Update,” the Department of Energy’s Office of Environmental Management (EM) reports that its contractor Savannah River Nuclear Solutions (SRNS) has successfully reduced degreasing solvents in the aquifer beneath the Savannah River Site in South Carolina using a technology that injects a form of iron and oil into groundwater.
“The oil attracts the Cold War[–era] cleaning solvents while the iron degrades and neutralizes the contamination,” said Shannan Lucero, SRNS manager for area closure projects.

The remediation of two former Soviet-era uranium mining sites in Kyrgyzstan has been completed on schedule and below budget, despite difficulties caused by the COVID-19 pandemic, the European Bank for Reconstruction and Development (EBRD) announced on March 28.

Canadian Nuclear Laboratories (CNL) is asking its stakeholders (members of the public, industry, elected officials, and employees) to support a proposal to construct the Near Surface Disposal Facility (NSDF) to dispose of legacy radioactive waste at the Chalk River Laboratories in Ontario.

The Department of Energy’s Office of Environmental Management (DOE-EM) has awarded a cleanup contract to North Wind Portage, Inc. for completion of environmental remediation of a uranium ore processing site near Moab, Utah. North Wind Portage is located in Idaho Falls, Idaho.
More information about the Moab project is available here.

Savannah River Nuclear Solutions (SRNS), the Department of Energy’s management and operating contractor for the Savannah River Site in South Carolina, has reached an agreement with the state of South Carolina and federal environmental regulators on the final cleanup of a 25-mile-long stream corridor at the site that was radiologically contaminated as a result of operations during the Cold War.
The corridor consists of Par Pond, nine miles of canals adjacent to the pond, and a stream named Lower Three Runs. The stream begins near the center of the site, just above Par Pond, and winds its way southward across SRS.

Soil and groundwater contamination at the Hanford Site’s 100-BC Area will be treated under a record of decision (ROD) signed by the Department of Energy and the Environmental Protection Agency, with the concurrence of the Washington State Department of Ecology.

Some of the major achievements of the nuclear safety cooperation agreement between the International Atomic Energy Agency and the European Union (EU) include more than 100 nuclear safety review missions, environmental remediation at former uranium sites in Central Asia, and more effective radioactive waste management in Africa.

The Department of Energy’s Office of Environmental Management (EM) is managing the release of tritiated water using a 62-acre plantation of pine trees and other natural resources to limit radioactively contaminated groundwater from reaching waterways on the Savannah River Site in South Carolina.

The Department of Energy is preparing to demolish two large, complex facilities at the Nevada Nuclear Security Site with ties to historical nuclear propulsion rocket development and testing programs. The DOE’s Environmental Management (EM) Nevada Program and its environmental program services contractor, Navarro Research and Engineering, have begun characterization and hazard reduction work on the site’s Engine Maintenance, Assembly, and Disassembly (EMAD) and Test Cell C (TCC) complexes.

The Savannah River Site is reducing the flow of hazardous and radioactive metal contaminants to South Carolina’s rivers and streams by injecting a mix of clean water and baking soda into the site’s groundwater. The base mix neutralizes groundwater that has become acidic as a result of SRS’s chemical separations work, helping restrict the flow of contaminants.

While it has been known for decades that bacteria known as Geobacter could clean up uranium waste, researchers at Michigan State University recently uncovered the biological mechanism behind the bacteria’s ability to do it.

Department of Energy site contractors Savannah River Nuclear Solutions and Savannah River Remediation received high marks from a recent independent audit of their environmental management work at the Savannah River Site in South Carolina.

The Department of Energy’s Office of Environmental Management will award the Idaho Cleanup Project contract for the Idaho National Laboratory site to Idaho Environmental Coalition (IEC), of Tullahoma, Tenn. The contract has an estimated ceiling of approximately $6.4 billion over 10 years, with cost reimbursement and fixed-price task orders to define the contract performance.

A silver chloride–based cleanup technology is expected to reduce radioactive iodine-129 contamination found in soil and groundwater near the center of the Department of Energy’s Savannah River Site in South Carolina to levels well below regulatory limits. The I-129 was created during the production of plutonium and tritium at the site throughout the Cold War era.

A project to passively remove nonradioactive contaminants from the soil and groundwater at the Department of Energy’s Savannah River Site in South Carolina is coming to an end, as workers prepare to remove solar-power “plugs” from 19 soil remediation locations at the site.
