Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

Two updated standards on criticality safety published
The American National Standards Institute (ANSI) recently approved two new American Nuclear Society standards covering different aspects of nuclear criticality safety (NCS).

Cost $50. Bus leaves from T Street exit, accessible from the Terrace Level.
NS Savannah, the world’s first nuclear-powered merchant ship. Christened in 1959 under President Dwight Eisenhower’s Atoms for Peace initiative, which challenged world leaders to develop peaceful uses of nuclear power, the ship served as a demonstration project for the potential maritime use of nuclear energy. On March 23, 1962, the NS Savannah became the first nuclear merchant ship at sea and is one of just four nuclear-powered cargo ships ever built. The vessel is equipped with a two-loop, 80 MWt pressurized water reactor.
During its time as an active merchant vessel, Savannah sailed more than 450,000 miles, serving as both a passenger cargo ship and a nuclear power educational ambassador. The ship was designated a National Historic Landmark in 1991 for “exhibiting exceptional value in illustrating nuclear, maritime, transportation, and political heritages of the United States.”
The S.S. JOHN W BROWN is the last remaining troop transport from WWII and the last to have landed troops ashore as part of an amphibious landing. It is also the oldest remaining Liberty Ship in the world. It was built in and now is homeported in Baltimore in the pier adjacent to the NS Savannah.
Transportation and Lunch are included.
NOTE: The guests will be transported by the bus and divided into two groups. The tours will take place concurrently, and all participants will gather at the Savannah for lunch. Following the meal, the groups will exchange tours. Kindly be aware that the ships do not adhere to ADA compliance standards.
