DOE to treat groundwater at Santa Susana Field Laboratory

In the November 10 Federal Register, the Department of Energy published a record of decision to begin groundwater remediation at the Santa Susana Field Laboratory site in Ventura County, Calif. The cleanup of groundwater will take place at seven locations within Area IV of the former industrial research and development complex.

Santa Susana’s Area IV contains the Energy Technology Engineering Center (ETEC), which was used for liquid metals research and where 10 nuclear research reactors were built and operated. Under an agreement with the state of California, the DOE is currently removing inactive buildings from the ETEC as part of the site cleanup.

Last of historic LLW removed from Lake Ontario shores

Canadian Nuclear Laboratories (CNL) announced on November 9 that it has completed the excavation and transfer of about 450,000 cubic meters of historic low-level radioactive waste (LLW) and contaminated soils away from the Lake Ontario shoreline in Southeast Clarington, Ontario. The waste resulted from radium and uranium refining operations of the former Canadian Crown corporation Eldorado Nuclear and its private sector predecessors, which operated from the 1930s to 1988.

CNL said the placement of the last truckloads of waste in the aboveground mound at the new long-term waste management facility, located about 700 meters north of the shoreline site, marks a milestone for the Port Hope Area Initiative (PHAI), Canada’s cleanup and long-term management response to LLW in the municipalities of Port Hope and Clarington. CNL is implementing the PHAI on behalf of Atomic Energy of Canada Limited.

Uranium mining settlement could fund new cleanup industry

The Santa Fe New Mexican, in its October 24 edition, reported on a study by the University of New Mexico’s Bureau of Business and Economic Research that found that the state could use money from a nearly $1- billion federal mining settlement to create a new industry around the cleanup of abandoned uranium mines in the Southwest.

DOE marks 75th anniversary of Trinity Test by highlighting cleanup progress

On July 16, 1945, the research and development efforts of the nation’s once-secret Manhattan Project were realized when the detonation of the world’s first atomic device occurred in Alamogordo, N.M., more than 200 miles south of Los Alamos, in what was code-named the Trinity Test—a name inspired by the poems of John Donne.

On the 75th anniversary of this landmark event, the Department of Energy’s Office of Environmental Management (EM) is highlighting the cleanup, long-term management, and historical significance of the Manhattan Project sites—Los Alamos, Oak Ridge, Tenn., and Hanford, Wash.—that were conceived, built, and operated in secrecy as they supported weapons development during World War II.

Under an agreement with the state of California, the Department of Energy will soon resume environmental cleanup of the Energy Technology Engineering Center (ETEC) at the Santa Susana Field Laboratory site in Ventura, Calif., about 36 miles northwest of Los Angeles. In a legal order signed on May 19 with the California Department of Toxic Substances Control, the department has agreed to demolish 10 of the remaining DOE-owned buildings within the ETEC, including several of the most contaminated buildings.
