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.
Technical Session|Panel|Modeling and Simulation for Fusion Neutronics

With the growth of the private fusion industry and a shift in R&D programs toward the engineering aspects of fusion energy systems, the study of neutronics is likely to play an increasingly important role in the overall design of fusion systems. The geometric complexity, deep shielding type problems, and needs for multiphysics integration and uncertainty quantification in fusion systems pose significant methodological challenges to be addressed by the fusion neutronics community. This panel brings together experts from industry, academia, and government laboratories to discuss the current state of fusion neutronics modeling and where challenges lay ahead.
