The spark of the Super: Teller–Ulam and the birth of the H-bomb—rivalry, credit, and legacy at 75 years
In early 1951, Los Alamos scientists Edward Teller and Stanislaw Ulam devised a breakthrough that would lead to the hydrogen bomb [1]. Their design gave the United States an initial advantage in the Cold War, though comparable progress was soon achieved independently in the Soviet Union and the United Kingdom.

Advanced reactor development offers the opportunity to re-evaluate site and facility security approaches in the U.S. and abroad. Given the differences between most advanced reactors and the existing large light water fleet, novel approaches such as risk-informed security-by-design (SeBD) and safety-and security-by-design (SSeBD) concepts provide reactor designers the ability to directly incorporate security features into their designs while crediting enhanced safety, security, lower risk profiles, smaller radiological source terms, and compact modular designs. This panel will provide perspectives from safety and security experts who will describe their current work in these areas.
