Big Science 2015-07-07T00:00:00Z This causes the uranium to change into an entirely new element, one that doesn’t occur in nature— scientists named it plutonium. Bomb 2012-01-01T00:00:00Z The key unsolved question was whether electromagnetic separation could produce more than a single uranium bomb core. Big Science 2015-07-07T00:00:00Z What staggered Hahn was that the force of the collision seemed to be causing the uranium atoms to split in two.

Big Science 2015-07-07T00:00:00Z A power plant based on element 94 would require perhaps a hundred pounds of the material, rather than the hundred tons thought to be necessary for uranium reactors. Big Science 2015-07-07T00:00:00Z Lawrence reasoned, however, that although domestic sources of uranium ore were practically nonexistent, uranium was plentiful in another form: tons of uranium tailings piled up as waste at Oak Ridge and Hanford. Big Science 2015-07-07T00:00:00Z Surrounding the uranium would be a tamper—a shield of very dense metal. Bomb 2012-01-01T00:00:00Z As long as the cadmium poles were in place, they would absorb the neutrons shooting out of the uranium.

Bomb 2012-01-01T00:00:00Z We have relatively abundant gold and uranium on Earth only because many supernova explosions had occurred just before the solar system formed. Cosmos 1980-01-01T00:00:00Z But a long-lived fissionable isotope, especially one that could be chemically separated from its uranium grandparent, might be especially suitable for a bomb.

If the human medicine didn’t work, then how did the uranium affect Pond? Isn’t uranium a human product?” Healer of the Water Monster 2021-05-11T00:00:00Z None of the four options for uranium enrichment—electromagnetic or thermal separation, gaseous diffusion, or the centrifuge—had clearly outdistanced the others, so none could be ruled out. Big Science 2015-07-07T00:00:00Z In 1950, uranium production from mines in Colorado increased sharply, exceeding Canadian output for the first time. Big Science 2015-07-07T00:00:00Z These atoms would also split, releasing still more neutrons, which would hit more uranium atoms, causing more fission, more free-flying neutrons, more fission, more neutrons, and so on. Bomb 2012-01-01T00:00:00Z Growing ever more puzzled, he quickly flicked through the rest of the files, which covered counterterrorism, the movement of uranium across Europe, and interrogation techniques.

Bomb 2012-01-01T00:00:00Z Conant had advised Bush to put the uranium project on the shelf for the duration of the war, but that advice had been based on his impression that a bomb was purely conjectural.

Bomb 2012-01-01T00:00:00Z The work, Wilson explained, had to do with uranium and fission and a whole new kind of bomb. Bomb 2012-01-01T00:00:00Z The speeding neutrons would collide with other uranium atoms, causing them to fission also. Bomb 2012-01-01T00:00:00Z That suggested that the activity resulted not from fission but from some other reaction—most likely the absorption of a neutron by the uranium nucleus. Big Science 2015-07-07T00:00:00Z From the slugs of irradiated uranium, fissile plutonium would be extracted at a second plant ten miles away, eventually to be sent on its way to Los Alamos. Big Science 2015-07-07T00:00:00Z The reaction would begin—speeding neutrons would hit uranium atoms, which would split, re- leasing energy and more neutrons.

Big Science 2015-07-07T00:00:00Z Natural uranium’s fission cross section—that is, the probability that the nucleus would fission under given circumstances—was highly sensitive to the energy of the impinging neutrons. Big Science 2015-07-07T00:00:00Z Even Harold Urey, who was a member of the Briggs committee, had no luck obtaining access to other scientists’ work to help him develop an isotope separation process for uranium.

Bomb 2012-01-01T00:00:00Z But this was tantamount to calling Lawrence’s bluff: at its current level of development, Ernest acknowledged, the calutron could produce enriched uranium fast but only in very small quantities. Big Science 2015-07-07T00:00:00Z But within less than one millionth of a sec ond, so many atoms would fission that the lump of uranium would blow itself apart with the force of millions of pounds of regular explosive.

In any case we have no uranium.” Bomb 2012-01-01T00:00:00Z This was a chilling clue—the Germans were grabbing all the uranium they could get. Bomb 2012-01-01T00:00:00Z It began in 1896 when Henri Becquerel in Paris carelessly left a packet of uranium salts on a wrapped photographic plate in a drawer. A Short History of Nearly Everything 2003-05-06T00:00:00Z That news, which broke in January 1939, launched physicists upon flights of learned speculation about the enormous energy released when the uranium nucleus split following its absorption of a stray neutron. Big Science 2015-07-07T00:00:00Z After the cyclotron, Lawrence would not receive another patent until wartime, when federal officials demanded that his inventive process for uranium separation be protected legally—and the patent rights be assigned permanently to the government. Big Science 2015-07-07T00:00:00Z The Allies may have used a very powerful bomb, he said, but not a real atomic bomb, not a bomb based on the fission of uranium atoms. Bomb 2012-01-01T00:00:00Z The main obstacle for the diffusion process being developed by Urey was its reliance on uranium hexafluoride gas, the detestable “hex,” which lived up to its nickname by severely corroding every permeable barrier Urey tried. Big Science 2015-07-07T00:00:00Z There are, of course, exceptions to this rule, such as gold or uranium, elements prized because of arbitrary economic conventions or aesthetic judgments, or because they have remarkable practical applications. Cosmos 1980-01-01T00:00:00Z Fission occurred even faster than expected in plutonium, causing a chain reaction to begin more quickly than in uranium. Bomb 2012-01-01T00:00:00Z Chemically distinct from uranium and therefore theoretically separable by chemical means, element 94 appeared to be about five times more fissionable than uranium.
