Yellowcake (also called urania) is a type of powdered uranium concentrate obtained from leach solutions, in an intermediate step in the processing of uranium ores. It is a step in the processing of uranium after it has been mined but before fuel fabrication or uranium enrichment. Yellowcake concentrates are prepared by various extraction and ...
6, a white solid, is highly reactive (by fluorination), easily sublimes (emitting a vapor that behaves as a nearly ideal gas), and is the most volatile compound of uranium known to exist. [107] One method of preparing uranium tetrachloride (UCl 4) is to directly combine chlorine with either uranium metal or uranium hydride. The reduction of UCl
Uranium-235 has a half-life of 703.8 million years. It was discovered in 1935 by Arthur Jeffrey Dempster. Its fission cross section for slow thermal neutrons is about 584.3 ± 1 barns. [1] For fast neutrons it is on the order of 1 barn. [2] Most neutron absorptions induce fission, though a minority (about 15%) result in the formation of uranium ...
This is when uranium glass reached the height of its popularity in the United States between 1958 and 1978, with more than 4 million pieces of decorative uranium produced, according to Oak Ridge ...
Photos of North Korea's uranium enrichment facility may show an undeclared site for building nuclear bombs just outside of its capital, analysts said. North Korea for the first time showed images ...
SEOUL (Reuters) -North Korea for the first time showed images of the centrifuges that produce fuel for its nuclear bombs on Friday, as leader Kim Jong Un visited a uranium enrichment facility and ...
Little Boy was a type of atomic bomb created by the United States as part of the Manhattan Project during World War II.The name is also often used to describe the specific bomb (L-11) used in the bombing of the Japanese city of Hiroshima by the Boeing B-29 Superfortress Enola Gay on 6 August 1945, making it the first nuclear weapon used in warfare, and the second nuclear explosion in history ...
By IAEA’s definition, around 42 kilograms (92.5 pounds) of uranium enriched to 60% is the amount at which creating one atomic weapon is theoretically possible — if the material is enriched ...
