Savannah River Nuclear Solutions (SRNS), the management and operations contractor for the Department of Energy’s Savannah River Site, has torn down a large industrial cooling tower at the site’s D Area complex. The cooling tower, built in 1952, is one of more than 30 structures being removed from SRS’s D Area as the DOE works to reduce the site’s footprint.

Crews are in the homestretch of completing demolition of Department of Energy–owned buildings at the former Energy Technology Engineering Center (ETEC) site in Ventura County, California, the agency reported on August 24.

Work crews have demolished the High Flux Beam Reactor (HFBR) exhaust stack at Brookhaven National Laboratory, on Long Island, N.Y., the Department of Energy’s Office of Environmental Management (EM) reported last week.

The 320-foot-tall red-and-white stack was decommissioned and demolished under the direction of the DOE, with oversight by the U.S. Army Corps of Engineers.

Demolition work: Removal of the stack started in early January using a concrete chimney demolition system called the MANTIS. Work crews dismantled the stack down to its base, about 36 feet above ground, before fully demolishing it in late February.

The next steps for the project are the cleanup of soils, the removal of the below-ground stack infrastructure, and verification that cleanup goals have been met. The Oak Ridge Institute for Science and Education will conduct independent verification of the stack cleanup, according to the DOE.

The first rail shipment of the stack’s debris to off-site disposal will involve 65 intermodal waste containers loaded onto a 10-railcar train. About 45 additional containers are expected to be shipped as part of the second and final waste shipment.
