If natural uranium is enriched to 3% U-235, it can be used as fuel for light water nuclear reactors. If it is enriched to 90% uranium-235, it can be used for nuclear weapons. Diagram of the principles of a Zippe-type gas centrifuge with U-238 represented in dark blue and U-235 represented in light blue.
Enriched uranium is a type of uranium in which the percent composition of uranium-235 (written 235 U) has been increased through the process of isotope separation.Naturally occurring uranium is composed of three major isotopes: uranium-238 (238 U with 99.2732–99.2752% natural abundance), uranium-235 (235 U, 0.7198–0.7210%), and uranium-234 (234 U, 0.0049–0.0059%).
VIENNA (Reuters) -Iran has informed the U.N. nuclear watchdog that it plans to install more than 6,000 extra uranium-enriching centrifuges at its enrichment plants and bring more of those already ...
VIENNA (Reuters) -Iran has installed half the advanced uranium-enriching machines it said earlier this month it would quickly add to its Fordow site dug into a mountain but has not yet brought ...
Centrifuges are the machines that enrich uranium transformed into gas by rotating it at very high speed, increasing the proportion of fissile isotope material (U-235).
The Helikon vortex separation process is an aerodynamic uranium enrichment process designed around a device called a vortex tube. Paul Dirac thought of the idea for isotope separation and tried creating such a device in 1934 in the lab of Peter Kapitza at Cambridge. [1]
Iran's IR-9 centrifuge, when operational, would have the ability to separate uranium isotopes more quickly than the current centrifuges being used, thereby enriching uranium at a faster pace. The ...
It's unclear if Iran has begun feeding the uranium yet into the centrifuges. Tehran so far has been vague about its plans. But starting the enrichment at 5% gives Tehran both leverage at negotiations with the West and another way to dial up the pressure if they don't like what they hear. Weapons-grade levels of enrichment are around 90%.
