Assistant Secretary for Environmental Management Tim Walsh Visits EM-Managed Fort St. Vrain Used Nuclear Fuel Storage Facility; New Well to Further Characterization of Hexavalent Chromium Plume at Los Alamos; and much more!

Department of Energy Assistant Secretary for Environmental Management Tim Walsh visited the Fort St. Vrain used nuclear fuel storage facility in Colorado to review site operations. The facility, which stores fuel from the former 330 MWe gas-cooled reactor that operated from 1979 to 1989, recently underwent infrastructure and security upgrades.

These activities highlight ongoing federal efforts to manage legacy nuclear materials and environmental remediation. In addition to the Colorado site visit, crews at Los Alamos National Laboratory completed a new groundwater monitoring well to track a hexavalent chromium plume, while demolition continues on contaminated facilities at Oak Ridge National Laboratory to support site modernization and hazard reduction.

PLATTEVILLE, Colo. — Assistant Secretary for Environmental Management (EM) Tim Walsh recently visited a used nuclear fuel storage facility in northern Colorado managed by the U.S. Department of Energy's (DOE) Idaho Cleanup Project and contractor Idaho Environmental Coalition (IEC).

Walsh toured the facility and several support buildings to better understand the Fort St. Vrain mission and its history. The facility safely stores used nuclear fuel generated by the former Fort St. Vrain Generating Station, a gas-cooled reactor that operated from 1979 to 1989. It was later shut down and decommissioned, and the site was converted to a natural gas-powered generating station.
