Transcript of 110513Seminar

Nobel Prize
in Chemistry 1934
Common Moderators
- Graphite, Light water, Heavy water

Heavy water
: Do NOT require enriched uranium
(Light water must use enriched uranium)
Nuclear reactor overheating
Harold C. Urey
Chemist at Columbia University.
"Discovery of isotope of Hydrogen"
In late 1931
Mass spectrometer could NOT find.
1. Evaporation
2. Triple point
Concentrated Deuterium at H triple point
Urey's Prediction
Chemical, physical atomic weight scale Study of H
Isotope of H might be PRESENT!
Ordinary H
Evaporated sample
Separation of the isotope ( Lab scale)
Industrial scale(2H, 10B, 235U)
World War II
G.N Lewis
Pure deuterium oxide
(Electrolytic method)
Deuterium oxide Electrolyzer
