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.
Diagram of a gas centrifuge with countercurrent flow, used for separating isotopes of uranium. A gas centrifuge is a device that performs isotope separation of gases. A centrifuge relies on the principles of centrifugal force accelerating molecules so that particles of different masses are physically separated in a gradient along the radius of a rotating container.
Gernot Zippe (November 1917 – 7 May 2008) was an Austrian mechanical engineer and a nuclear physicist of German origin who is widely credited with leading the team which developed the Zippe-type centrifuge– a centrifuge machine for the enrichment and collection of uranium-235, during his time in the former Soviet program of nuclear weapons.: 47 [1]
The National Enrichment Facility (NEF) is a nuclear facility for the enrichment of uranium associated with the Los Alamos National Laboratory. The plant uses a gas centrifuge technology known as Zippe-type centrifuges. It is located 5 miles (8.0 km) east of Eunice, New Mexico. [1]
The company hopes to triple its Oak Ridge workforce in a bid to end U.S. reliance on Russia for enriched uranium. Centrus puts up $60M for centrifuges to replace Russian reliance with Oak Ridge ...
American Centrifuge Achieves Two RD&D Program Milestones BETHESDA, Md.--(BUSINESS WIRE)-- USEC Inc.'s (NYS: USU) American Centrifuge uranium enrichment technology recently achieved two important ...
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).
Gaseous diffusion uses microporous membranes to enrich uranium. Gaseous diffusion is a technology that was used to produce enriched uranium by forcing gaseous uranium hexafluoride (UF 6) through microporous membranes. This produces a slight separation (enrichment factor 1.0043) between the molecules containing uranium-235 (235 U) and uranium ...
