It’s safe to say that readers of Nuclear News are familiar with decommissioning. It’s even safe to assume that experienced decommissioning practitioners are familiar with the National Historic Preservation Act (NHPA) and how it applies to typical projects. What’s different about the N.S. Savannah is that the entire project site is a historic property—and in fact, is a federally owned National Historic Landmark (NHL), a status that confers the highest level of protection under law. Federal owners of NHLs are obligated to minimize harm in both planning and actions. Distilled to its salient point, no federal owner of an NHL should destroy it if there’s a reasonable alternative. That level of preservation is not what we normally associate with nuclear decommissioning. This perfectly summarizes the challenges, and opportunities, that decommissioning Savannah offered. The story of how the Maritime Administration (MARAD) managed these two otherwise contradictory processes showcases how historic preservation and decommissioning can positively intersect, provides a pathway for other historic facilities, and further adds to the already illustrious history of one of our nation’s significant 20th century landmarks.

ANS’s first Virtual Trivia Night drew over 80 contestants who were ready to test their nuclear knowledge during an evening of Zoom-based socialization sponsored by the ANS Young Members Group, the Student Sections Committee, and the Diversity and Inclusion in ANS Committee. YMG Vice Chair Catherine Prat hosted the May 8 event. “I really appreciated seeing how engaged the players were throughout the night,” she said. “They were great guinea pigs for this first-of-a-kind event, as we continue to explore ways to connect virtually.”
