Uranium is a chemical element with symbol U and atomic number92. It is a silvery-white metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium is weakly radioactive because all its isotopes are unstable (with half-lives of the six naturally known isotopes, uranium-233 to uranium-238, varying between 69 years and 4.5 billion years). The most common isotopes of uranium are uranium-238 (which has 146 neutrons and accounts for almost 99.3% of the uranium found in nature) and uranium-235 (which has 143 neutrons, accounting for 0.7% of the element found naturally). Uranium has the second highest atomic weight of the primordially occurring elements, lighter only than plutonium. Its density is about 70% higher than that of lead, but slightly lower than that of gold or tungsten. It occurs naturally in low concentrations of a few parts per million in soil, rock and water, and is commercially extracted from uranium-bearing minerals such as uraninite.
That's $1.972 billion more than last year's funding.$810 million for the Uranium Processing Facility at Y-12 in Oak Ridge...I believe they put $800 million on the Uranium Processing Facility in the president's budget and allow me to address that.
K-25 was the largest of all the Oak Ridge sites, and its process for enriching uranium would ultimately prove to be the most successful ... From K-25, the uranium was fed into Y-12's machines to be enriched even further.
Depleted Uranium... Depleted uranium (DU) is a byproduct of the uranium enrichment process, primarily composed of uranium-238 with a reduced concentration of uranium-235 ... The primary concern associated with depleted uranium is its radioactive properties.
We don’t yet know what happened at the targets ... Of perhaps greater significance, the city is at the heart of Iran’s nuclear programme with a research site as well as a processing facility, including stockpiles of highly enriched uranium ... .
So this whole process has been a whole bunch of speed bumps on the way here ... And what happened for 70 years, we were told that we were enriching uranium and doing nothing but uranium ... We have three huge process buildings.
The Islamic Republic has several nuclear research sites, two uranium mines, a research reactor and uranium processing facilities - including three uranium enrichment plants.
Iran does not officially possess nuclear weapons, though Tehran has been enriching uranium at levels closer to weapons production since a nuclear deal fell apart in 2018 after former President Trump withdrew from the pact.
