Enriched uranium is a type of uranium in which the percent composition of uranium-235 (written 235U) has been increased through the process of isotope...

research sites, two uranium mines, a research reactor, and uranium processing facilities that include three known uranium enrichment plants. Commencing...

natural uranium, but light water reactors must use low enriched uranium because of the higher neutron absorption of light water. Uranium enrichment removes...

enriching is downblending. Surplus highly enriched uranium can be downblended with depleted uranium or natural uranium to turn it into low-enriched uranium...

the 38.53 kilograms (84.9 lb), 80%-enriched, cylindrical "projectile" was an insufficient amount of enriched uranium to be a "bare sphere" critical mass...

abundance of uranium-235 in natural uranium (which is, overwhelmingly, mostly uranium-238), uranium needs to undergo enrichment so that enough uranium-235 is...

nature, and natural uranium is about 99.3% uranium 238 (U-238) and 0.7% U-235. Therefore, to make a weapon, either uranium must be enriched or plutonium must...

codename given by the Manhattan Project to the program to produce enriched uranium for atomic bombs using the gaseous diffusion method. Originally the...

enriching uranium, which produces fuel for nuclear reactors and nuclear weapons. Uranium dioxide is converted with hydrofluoric acid (HF) to uranium tetrafluoride:...

emission. Enriched uranium contains more 234U than natural uranium as a byproduct of the uranium enrichment process aimed at obtaining uranium-235, which...

of Piketon, Ohio, that previously produced enriched uranium, including highly enriched weapons-grade uranium, for the United States Atomic Energy Commission...

more enriched uranium from a given amount of natural uranium, by re-enriching tails ultimately leaving a depleted uranium tail of lower enrichment. This...

use uranium enriched to 3–5% U-235, the only fissile isotope that is found in significant quantity in nature. One alternative to this low-enriched uranium...

the near future. Most nuclear power plants use thermal reactors with enriched uranium in a once-through fuel cycle. Fuel is removed when the percentage of...

enriched uranium fuel to low-enriched uranium, and to supply the low-enriched uranium to Iran in 1987–88. TRR core was converted to use Low Enriched Uranium...

nuclear program, making the Soviet Union the most effective supplier of enriched uranium. Franz Simon, Rudolf Peierls, Klaus Fuchs and Nicholas Kurti made important...

Pennsylvania was investigated for losing 200–600 pounds (91–272 kg) of highly enriched uranium, with suspicions that it had gone to Israel's nuclear weapons program...

COVID-19 pandemic. NTI supported the development of an international low-enriched uranium bank to help prevent the proliferation of nuclear technology. NTI advisor...

use enriched uranium. Nuclear weapons take a concentration of 90% uranium-235, and light water reactors require a concentration of roughly 3% uranium-235...

It is a step in the processing of uranium after it has been mined but before fuel fabrication or uranium enrichment. Yellowcake concentrates are prepared...

separating natural uranium into enriched uranium and depleted uranium is the largest application. In the following text, mainly uranium enrichment is considered...

Nigeria. In 2018, NIRR-1 completed a conversion from high-enriched uranium fuel to low-enriched fuel. NIRR-1 is a Miniature neutron source reactor (MNSR)...

Fordow Fuel Enrichment Plant (FFEP) is an Iranian underground uranium enrichment facility located 20 miles (32 km) northeast of the Iranian city of Qom...

produce enriched uranium by forcing gaseous uranium hexafluoride (UF6) through microporous membranes. This produces a slight separation (enrichment factor...

Project, to build a nuclear explosive. In May 1944, the first grams of enriched uranium ever produced reached criticality in the low power (LOPO) reactor at...

their fuel requires more highly enriched uranium, typically up to 20% U-235, although some use 93% U-235; while 20% enrichment is not generally considered...

neutron moderator. PHWRs frequently use natural uranium as fuel, but sometimes also use very low enriched uranium. The heavy water coolant is kept under pressure...

percentage of 235U, enrichment produces large quantities of depleted uranium. For example, producing 1 kilogram (2.2 lb) of 5% enriched uranium requires 11.8...
