Before and after views of the demolition of Building 175 at Lawrence Livermore National Laboratory.
EM partnered with Lawrence Livermore National Laboratory (LLNL) and the U.S. Army Corp of Engineers (USACE) to complete the recent demolition of a building and removal of a reactor to make room for new facilities on the lab’s 1-square-mile footprint.
During an EM cleanup project, crews drained and deactivated 8,500 feet of piping of the East Column Exchange (COLEX) equipment at the Alpha-4 facility at the Y-12 National Security Complex. These efforts retrieved 2.3 tons of mercury and prevented a potential release into the environment.
EM has prepared the East Column Exchange (COLEX) equipment at Oak Ridge for demolition following deactivation work that involved retrieving mercury from the deteriorating structures to prevent a potential environmental release.
Waste retrieval from Tank AX-101, the last of four tanks to be retrieved in the Hanford Site’s AX Farm, is set to begin this fall. This in-tank photo shows the salt-based waste and the tank’s 22 air-lift circulators.
Tank by tank, batch by batch, the EM Office of River Protection (ORP) & tank operations contractor Washington River Protection (WRPS) are reducing risk to the environment by retrieving waste from the Hanford Site’s single-shell waste-storage tanks.
