WebEnriched Uranium HEU is defined as uranium that has the fraction of the fissile isotope 235U greater than 20%, LEU is less than 20%. From: Comprehensive Nuclear Materials, 2012 View all Topics Add to Mendeley About this page Nuclear Proliferation and Diversion H.A. Feiveson, in Encyclopedia of Energy, 2004 8.2 Research Reactors Using HEU WebHighly enriched uranium is considered weapons-grade when it has been enriched to about 90% U-235. [citation needed] U-233 is produced from thorium-232 by neutron capture. The U-233 produced thus does not require enrichment and can be relatively easily chemically separated from residual Th-232.

Fact Sheet: Uranium Enrichment: For Peace or for Weapons

Webhighly enriched uranium or "HEU" means the equivalent (in terms of uranium and enrichment content) of 50 metric tons of uranium with an average Assay of approximately forty percent (40%) as either metal (hollow cylinders, broken or sheared pieces, and other small pieces) or oxide (either UO (3) or U (3)O (8). Sample 1 Based on 1 documents Save Copy WebThis small mass difference allows the isotopes to be separated and makes it possible to increase (enrich) the percentage of U-235 in uranium.
