ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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.

Webinar: MC&A and safety in advanced reactors in focus
Towell
Russell
Prasad
The American Nuclear Society’s Nuclear Nonproliferation Policy Division recently hosted a webinar on updating material control and accounting (MC&A) and security regulations for the evolving field of advanced reactors.
Moderator Shikha Prasad (CEO, Srijan LLC) was joined by two presenters, John Russell and Lester Towell, who looked at how regulations that were historically developed for traditional light water reactors will apply to the next generation of nuclear technology and what changes need to be made.

Following his groundbreaking “Atoms for Peace” speech before the United Nations on December 8, 1953, President Eisenhower in 1955 proposed the design and construction of a nuclear-powered merchant ship. With congressional approval in 1956, the 22,000 ton passenger and cargo ship NS Savannah was constructed, tested, and delivered for sea service in 1962. The purpose of the Savannah was to demonstrate the application of nuclear technology (80 MWth PWR) to merchant ships with all its new concomitant regulations, standards, training, operations, and design features. Between 1962 and 1970, when it was shutdown, Savannah had sailed over 450,000 miles, called 32 domestic and 45 foreign ports in 26 nations, carried 848 passengers, and hosted over 1.4 million visitors, all while burning only 163 pounds of enriched uranium.
An in-depth detailed virtual tour of the Savannah, now berthed in Baltimore, was developed under sponsorship by the ANS DC Section, N.S. Savannah Association, and the Maritime Administration (MARAD). This approximately 1-hour video tour takes viewers on a journey, which could not be taken in person, around and inside the Savannah which is undergoing decommissioning and decontamination (D&D). Extensive video footage accompanied by knowledgeable expert commentary was taken of the nuclear steam supply system (NSSS) inside the containment, control room, engine room, bridge, cargo holds, and public areas. The video of the interior of the containment is especially historic as component removal began right after film shooting in October 2021. Unique D&D design modifications are also featured in this virtual tour. The MARAD Savannah Project Director and the last Savannah Reactor Operator discuss design and operating features as well as memories.
A special thank you to the tour sponsors
