Summary
DescriptionCumuative Shipments of U-235 from Y-12 to Los Alamos 1944-1946.png |
English: During the Manhattan Project, the final stage of uranium enrichment was performed by the Y-12 plant at Oak Ridge, Tennessee. The "product" was then shipped to Los Alamos for machining and casting. This graph shows the volume of product shipped to Los Alamos under the auspices of the Manhattan Project, which lasted until its abolishment at the end of December 1946 (at which point the US Atomic Energy Commission took over all of its property and operations). Of note on the graph is the rough indication of the assembly of the Hiroshima bomb (the final pieces were sent to Tinian at the end of July 1945), which had 64 kilograms of (on average) 80% enriched uranium as its nuclear fuel. Note that the enrichment level of the uranium on this graph is not equal: the uranium shipped in 1944, for example, had an average enrichment level no higher than 70.6% (per page 4 in the same document this chart came from). By July 1945, this average had been raised to 81.6%, and by December 29, 1946, the average enrichment level of the 1,041,026.5 grams of uranium shipped was over 90% (either "approx. 93%" or "approx. 95%" — the document's final digit is obscured).
The overall appendix has the date "10/7/47" written on its cover, though it may have been written earlier than this (it contains data through December 31, 1946). |
