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.
2023 ANS Student Conference Speaker
Julie Ezold has 30 years’ experience in the nuclear sciences and is currently the Californium-252 Program Manager; a multi-million-dollar enterprise that includes the production of Berkelium-249, Einsteinium-253, and other trans-curium products. These trans-curium products have been used in the discovery of a new element, Element 117, aptly named Tennessine. Previously she was the Radioisotope Production and Operations Section Head; responsible for managing the production and optimization of all radioisotopes that are in a continuing and sustained state of demand and production beyond the research and development phases. Ms. Ezold has actively supported nuclear science educational activities through the Nuclear Science and Engineering Directorate’s Educational Outreach Committee, K-2 Science Club, Mentor Program, and others. Ms. Ezold holds a BS, Nuclear Engineering from Rensselaer Polytechnic Institute and a Masters, Nuclear Engineering, from North Carolina State University. Her master’s research, “Determination of Iodine-129 Production in Light Water Reactors”, was conducted at the High Flux Isotope Reactor at ORNL. After completing her master’s, she joined the staff at ORNL and has held positions in engineering, waste management, criticality safety, and isotope production. Ms. Ezold has been an active ANS member since 1988; where she is currently serving on the Board of Directors and is Chairperson of the Scholarship Policy and Coordination Committee.
