Uranium 235 Definition & Meaning - Merriam-Webster
WebThis small mass difference allows the isotopes to be separated and makes it possible to increase (enrich) the percentage of U-235 in uranium. Most civilian power reactors use enriched uranium fuel containing 0.8 to 8.0% U-235, known as low enriched uranium (LEU). WebThis incident does not fit the definition of war terrorism.

WebEnriched-uranium definition: Uranium enriched with a much higher than normal amount of the fissile isotope U-235; used in nuclear reactors and nuclear weapons. ... We should set … Enriched uranium is a type of uranium in which the percent composition of uranium-235 (written U) has been increased through the process of isotope separation. Naturally occurring uranium is composed of three major isotopes: uranium-238 ( U with 99.2739–99.2752% natural abundance), uranium-235 ( U, … See more Uranium as it is taken directly from the Earth is not suitable as fuel for most nuclear reactors and requires additional processes to make it usable (CANDU design is a notable exception). Uranium is mined either … See more "Separative work" – the amount of separation done by an enrichment process – is a function of the concentrations of the feedstock, the enriched output, and the depleted tailings; and is expressed in units that are so calculated as to be proportional to the … See more The opposite of enriching is downblending; surplus HEU can be downblended to LEU to make it suitable for use in … See more During the Manhattan Project, weapons-grade highly enriched uranium was given the codename oralloy, a shortened version of See more Isotope separation is difficult because two isotopes of the same element have nearly identical chemical properties, and can only be separated gradually using small mass differences. ( U is only 1.26% lighter than U). This problem is compounded because uranium is rarely … See more In addition to the separative work units provided by an enrichment facility, the other important parameter to be considered is the mass of natural uranium (NU) that is needed … See more The following countries are known to operate enrichment facilities: Argentina, Brazil, China, France, Germany, India, Iran, Japan, the Netherlands, North Korea, Pakistan, Russia, the United Kingdom, and the United States. Belgium, Iran, Italy, and Spain hold an … See more 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).
