Retired Lt. Gen. Ernest Graves sits at the control panel of the deactivated SM-1 nuclear reactor and power plant at Fort Belvoir during a site visit Tuesday September 19, 2017. As a major with the U.S. Army Corps of Engineers, Graves oversaw the completion of the construction of the facility and its initial operation in the late 1950s. While SM-1’s reactor was deactivated in 1973 and placed into safe storage, the U.S. Army Corps of Engineers is in the process of planning for the reactor’s final decommissioning and dismantlement for the facility. Bringing Graves to the facility served two main purposes: allowing the team to gather as much information as possible about the construction of the facility; and providing historical context and additional history of SM-1’s operation.
