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.
Uranium Chemistry Tutorial
December 8, 2020|10:30AM–12:00PM (11:30AM–1:00PM EST)
Available to 2020 ANS Virtual Winter Meeting Attendees
ANS Members, please log in to watch this webinar.
This is part four of a nine-part tutorial series exclusively available to 2020 ANS Winter Meeting attendees.
Examples where chemistry has unexpectedly impinged (or might have impinged) on criticality control are explored.
Case 1: How poor engineering altered the chemistry of a dissolver system and caused an unexpected criticality hazard… or how a lack of engineering know-how fooled the chemists.
Case 2: How a criticality safety improvement made things less safe as chemistry triumphed over physics.
Case 3: How chemistry fooled even the chemists.
