The restart of Palisades nuclear power plant in Covert, Mich., has hit a milestone with the passivation of its primary system, plant owner Holtec International announced Monday, even as a firm restart date has yet to be announced.
Passivation is a chemical process that improves corrosion resistance by making plant materials less reactive. During the process, the reactor’s primary system was brought to normal operating temperature and pressure. Holtec called this passivation phase an “essential step” in maintaining the long-term reliability of equipment.

Built in 1959, NS Savannah (NSS) was the world's first nuclear powered merchant ship and served as a signature element of President Eisenhower's Atoms for Peace program. While in service, NSS demonstrated the peaceful use of atomic power as well as the feasibility of nuclear-powered merchant vessels. The vessel was retired from active service in 1970 and registered as a National Historic Landmark in 1991. NSS is currently part of MARAD's National Defense Reserve Fleet (NDRF) in retention status. This session will examine the history of other civilian nuclear-powered vessels including the Sturgis, the Otto Hahn and the Russian non-naval vessels.
