Enriched uranium is a kind of uranium in which the percent composition of uranium-235 has been increased through the process of isotope separation. Natural uranium is 99.284% 238 U isotope, with 2...

Highly enriched uranium can be diluted, or "blended down" with depleted, natural, or very low-enriched uranium to produce 3 to 5 percent low-enriched reactor fuel. Uranium metal at various enrichments must be chemically processed so that it can be blended into a homogeneous material at one enrichment level.

Under the U.S.-Russian Highly Enriched Uranium (HEU) Purchase Agreement, 500 tons of HEU from dismantled Russian nuclear weapons enough material to make over 30,000 nuclear weapons[1] is to be blended to proliferation-resistant low-enriched uranium (LEU) by 2013. The material is being sold to the United States for re...

Plutonium and highly enriched uranium (HEU) are the basic materials used in nuclear weapons. Plutonium also plays an important role in the generation of nuclear electricity. Knowing how much plutonium and HEU exists, where, in which form and under which controls is vital for international security and nuclear commerce.
