The Department of Energy’s Office of Environmental Management and its cleanup contractor at the West Valley Demonstration Project have removed the largest of nine tanks from a liquid waste cell as part of the ongoing demolition of the Main Plant Process Building, the office announced on February 6.

A team of designers from Central Plateau Cleanup Company (CPCCo), a contractor of the DOE-EM Richland Operations Office, is using 3D laser scanning technology to gather data to help workers prepare some of the facilities at the Hanford Site for demolition.

The Molten Salt Reactor Experiment (MSRE) facility is one of hundreds of old, contaminated buildings at Oak Ridge National Laboratory and the Y-12 National Security Complex in Tennessee that are slated to be taken down.

A new animated video from the Department of Energy's Office of Environmental Management (EM) shows how cleanup contractor CH2M HILL BWXT West Valley (CHBWV) will take down the main plant process building at the West Valley Demonstration Project (WVDP).

The EM team at West Valley wanted to convey the project to the public, and they believe the animation accomplishes that goal, according to Stephen Bousquet, EM WVDP federal project director for the Main Plant Deconstruction Project.

In a first for the Department of Energy’s Oak Ridge Site, a former reactor facility is being demolished. The site’s cleanup contractor, UCOR, began tearing down the Bulk Shielding Reactor, also known as Building 3010, last week.

“While this project is not the biggest demolition we’ve undertaken, it carries a lot of significance,” said Laura Wilkerson, acting manager for the Oak Ridge Office of the DOE’s Office of Environmental Management (EM). “It is the first removal of a former reactor at [Oak Ridge National Laboratory], and it is a signal of much more to come at the site in the immediate future.”

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.
