The STURGIS, a former World War II Liberty Ship, was converted into the first floating nuclear power plant in the 1960s. Before being shutdown in 1976, the STURGIS’ nuclear reactor, MH-1A, was used to generate electricity for military and civilian use in the Panama Canal. It is important to note that the MH-1A reactor has no nuclear fuel or special nuclear material. The reactor was de-fueled, decontaminated for long-term storage, and sealed before being towed to the James River Reserve Fleet at Joint Base Langley Eustis, Virginia; where it was stored and maintained since 1978, except for times of periodic dry dock maintenance.
