UF6, which is solid at room temperature but is easily vaporized, was the best choice Fig.
Iran is to refrain from feeding uranium hexafluoride
into its installed centrifuges that are not enriching uranium.
, a toxic gas, is the form of uranium used in the enrichment process.
Although the enrichment facility was undergoing maintenance work at the time of the visit, an engineer gave an explanation showing the entire process for manufacturing uranium hexafluoride
from yellow cake, which is uranium ore crushed to a fine powder.
Its report is expected to focus on Iran's work with devices that spin uranium hexafluoride
gas to produce low-enriched uranium for power plants or highly enriched uranium for weapons, depending on the duration of the process.
Uranium Participation is an investment holding company created to invest at least 85 per cent of its assets in uranium oxide concentrates and uranium hexafluoride
In 2000, USEC discovered that 9,550 metric tons of that inventory may have contained elevated levels of technetium, making it out-of-specification according to standards for uranium hexafluoride
for enrichment as set by the American Society for Testing and Materials.
Yellow cake' is put through a series of chemical processes and heated to turn into a gas, uranium hexafluoride
Then this crumbled material is heated to produce a gas, uranium hexafluoride
The EU-Iran talks, which in 2004 began with an agreement in Paris, broke down after Tehran denounced an EU offer as inadequate and resumed production of uranium hexafluoride
, a nuclear feedstock, at a plant in Isfahan.
The State Department claimed it had information that Iran was adapting missiles to carry nuclear warheads, and the White House pointed to reports that Iran had accelerated the production of uranium hexafluoride
, a gas used in the production of nuclear weapons.
It recently started producing uranium hexafluoride
at its plant in Isfahan, the diplomats said.
