LIVERMORE, Calif. — Crews with the U.S. Department of Energy Office of Environmental Management (EM) have made steady progress removing a legacy research reactor dome, Building 280, located on the Lawrence Livermore National Laboratory site. EM, in coordination with the U.S. Army Corps of Engineers and other partners, is performing radioactive waste management and excess facility demolition at the laboratory site to open space for new opportunities on the laboratory’s small footprint. The first photo shows the dome on Nov. 19. It compares with the second photo taken Dec. 8, following work to remove it.
