  • M-1392 Publication Title: Bush-Conant File
    Publication Number: M-1392 Publication Title: Bush-Conant File Relating to the Development of the Atomic Bomb, 1940-1945 Date Published: n.d. BUSH-CONANT FILE RELATING TO THE DEVELOPMENT OF THE ATOMIC BOMB, 1940-1945 The Bush-Conant File, reproduced on the 14 rolls of this microfilm publication, M1392, documents the research and development of the atomic bomb from 1940 to 1945. These records were maintained in Dr. James B. Conant's office for himself and Dr. Vannevar Bush. Bush was director of the Office of Scientific Research and Development (OSRD, 1941-46), chairman of the National Defense Research Committee (NDRC) prior to the establishment of OSRD (1940-41), chairman of the Military Policy Committee (1942-45) and member of the Interim Committee (May-June 1945). During this period Conant served under Bush as chairman of the National Defense Research Committee of OSRD (1941-46), chairman of the S-1 Executive Committee (1942-43), alternate chairman of the Military Policy Committee (1942-45), scientific advisor to Maj. Gen. Leslie R. Groves (1943-45), and member of the Interim Committee (May-June 1945). The file, which consists primarily of letters, memorandums, and reports, is part of the Records of the Office of Scientific Research and Development, Record Group (RG) 227. The Bush-Conant File documents OSRD's role in promoting basic scientific research and development on nuclear fission before August 1942. In addition, the files document Bush and Conant's continuing roles, as chairman and alternate chairman of the Military Policy Committee, in overseeing the army's development of the atomic bomb during World War II and, as members of the short-lived Interim Committee, in advising on foreign policy and domestic legislation for the regulation of atomic energy immediately after the war.

  • Early Planning for Construction of Y-12
    Early planning for construction of Y-12 Last week we examined the interactions and influences leading to a full scale electromagnetic separation production plant in East Tennessee. We noted that James B. Conant, President of Harvard University and a strong member of the S1 Committee, was a key factor in getting the electromagnetic separation technology selected as one of the three main approaches to getting enough uranium 235 or plutonium 239 for atomic weapons. One story I heard just this last week from a local Oak Ridger, Harold McCurty, who shared some historical documents with me and who is a member of the ’43 Club, fit right in line with the research I have been doing on how the decision to construct Y-12 was made. He said he recalled hearing the story that Ernest O. Lawrence had become discouraged because he could not seem to get the right people to understand the electromagnetic separation process well enough to support it over the other methods to separate uranium. McCurty’s recollection of the story has Conant taking Lawrence for a walk where they agreed to try one more time to convince the decision makers that Lawrence’s calutrons would do the job. Both of them were convinced that Lawrence’s calutrons likely could separate enough uranium 235 for a bomb well ahead of gaseous diffusion or any other separation method. When he returned to the meeting, Conant made a strong defense of Lawrence’s research and first agreed to a smaller facility than Lawrence wanted built. However, this got their foot in the door with the calutrons and later the Y-12 construction effort was expanded several times, finally installing 1152 calutrons in nine major buildings! Earlier in 1942, the experimentation at Berkeley by Lawrence and his staff had been expanded to include the giant 184-inch magnet - the largest magnet in existence at the time.

  • Manhattan Project “The Effects Could Well Be Called Unprecedented, Magnificent, Beautiful, Stupendous and Terrifying
    Quickwrite Mind Map: War Background: The Manhattan Project “The effects could well be called unprecedented, magnificent, beautiful, stupendous and terrifying. No man-made phenomenon of such tremendous power had ever occurred before. The lighting effects beggared description. The whole country was lighted by a searing light with the intensity many times that of the midday sun. It was golden, purple, violet, gray and blue. It lighted every peak, crevasse and ridge of the nearby mountain range with a clarity and beauty that cannot be described but must be seen to be imagined. It was the beauty the great poets dream about but describe most poorly and inadequately.” -- Brigadier General Thomas F. Farrell, Deputy Commander to General Leslie R Groves "We knew the world would not be the same. A few people laughed, a few people cried, most people were silent. I remembered the line from the Hindu scripture, the Bhagavad-Gita. Vishnu is trying to persuade the Prince that he should do his duty and to impress him takes on his multi-armed form and says, ‘Now, I am become Death, the destroyer of worlds.’ I suppose we all felt that one way or another." -- J.

The fuel would contain the fissile material needed to support the fission process. The neutrons generated by the fission process had to be slowed by the moderator so that they could initiate addi- tional fission reactions. The heat that resulted from this process had to be removed by the coolant. Fermi’s initial research explored the possibility of a chain reaction with natural urani- The 1930s were a time of rapid progress in the development of nuclear physics. um.

  • Memories of Secret City Days1
    MEMORIES OF SECRET CITY DAYS1 William J. (Bill) Wilcox Jr., Oak Ridge City Historian Retired Technical Director for the Oak Ridge Y-12 & K-25 Plants [During the Manhattan Project (from May 25, 1943) a Jr. Chemist, Tennessee Eastman Corp., Y-12 Plant] A Guest Column for the Newspaper Based on the Memoirs Paper, June, 19991 We need to go back to the early days of 1939 for a little background in telling why Oak Ridge came to be in World War II and to appreciate better the remarkable things that were done here. PRELUDE In January of 1939, two brilliant chemists over in Germany proved that if you bombard the heavy ele- ment uranium with neutron radiation, some of the uranium atoms split in two and become entirely different elements of about half the weight of uranium, like barium and lanthanum. And when the atom's nucleus splits, a huge amount of energy is released-10 million times the energy released in chemical reactions we are familiar with, like burning coal and gasoline, or exploding dynamite and TNT. The physicists in those days were working with only microscopic amounts of uranium, but could detect the energy released easily. Nu- clear energy is the energy of the universe-God’s way- the energy of the sun that keeps us warm. On the grand scale, nuclear energy is the most common kind; the chemical energy that we humans know is a rare thing only known on planets such as ours! Now a significant aspect of this finding was that the world in January 1939 was still at peace, so this exciting development was immediately published in a scientific journal read by scientists in every country all over the world.
