Department of Physics, Alma College, 48801, Alma, MI, USA aut Liquid Thermal Diffusion during the Manhattan Project [Elektronische Daten] [B. Cameron Reed] On the basis of Manhattan Engineer District documents, a little known Naval Research Laboratory report of 1946, and other sources, I construct a more complete history of the liquid-thermal-diffusion method of uranium enrichment during World War II than is presented in official histories of the Manhattan Project. This method was developed by Philip Abelson (1913-2004) and put into operation at the rapidly-constructed S-50 plant at Oak Ridge, Tennessee, which was responsible for the first stage of uranium enrichment, from 0.72% to 0.85% U-235, producing nearly 45,000 pounds of enriched U-235 by July 1945 at a cost of just under $20 million. I review the history, design, politics, construction, and operation of the S-50 liquid-thermal-diffusion plant. Springer Basel AG, 2010 Philip H. Abelson nationallicence Lyman J.
