We recently welcomed Timothy Walsh, the assistant secretary of the U.S. Department of Energy Office of Environmental Management (EM) and Ray Geimer, the manager for DOE’s Hanford Site Field Office, to PNNL.
With roots in the Manhattan Project and Hanford Site, PNNL has supported the EM mission for nearly 60 years. Our expertise and innovations are helping to shape cleanup at Hanford and across the nation.
During the visit, PNNL researchers demonstrated our expertise, innovation, and operational support in glass and grout waste forms as well as soil and groundwater remediation. PNNL also showcased our leadership in artificial intelligence and energy resiliency.
