enriched uranium

Uranium with a higher concentration of the radioisotope 235U than is found in natural uranium ore. The isotope 235U is used to manufacture nuclear fuel rods (for electrical power generation) and nuclear weapons. See: depleted uranium

'In this regard, Ghanaian scientists in collaboration with Scientists and Experts from the Argonne National Laboratory (ANL) and Idaho National Laboratory (INL) of the United States Department of Energy (US DoE), the International Atomic Energy Agency (IAEA) and China Institute of Atomic Energy, undertook the process of converting our high-enriched uranium fuel reactor to low-enriched uranium fuel one,' he remarked.
The fuel in question is from UK nuclear research programs spanning more than four decades and contains plutonium and high-enriched uranium. They are potentially recyclable and are therefore not classified as waste, but require enhanced security.
'The Yongbyon nuclear complex includes a small research reactor called the IRT-2000, a 5MW(e) gas-graphite moderated reactor, an unfinished 50MW(e) reactor, a spent fuel reprocessing facility, multiple waste storage sites, a uranium enrichment facility, and light water reactor.' Precisely, it contains both Radiochemical Laboratory (Reprocessing plant) to produce weapons-grade plutonium, Fuel Fabrication complex that includes the Uranium Enrichment Plant to produce weapons-grade high-enriched uranium.
Iran's current timeframe for acquiring enough high-enriched uranium to make a nuclear bomb--known as breakout time--is around two or three months, and the United States wants a deal that extends that period to at least one year (see "Iran's Nuclear Breakout Time: A Fact Sheet," PolicyWatch 2394).
In that time, the Russians dismantled about 20,000 nuclear warheads, processed their high-enriched uranium cores into low-enriched fuel, and sent it to the United States.
Uniform sanctions from the international community have taken their toll on Iran, and the two writers note, "perhaps it is their public's strengthening attitude favoring concessions that has convinced Iran's leaders to admit misleading the IAEA about past nuclear advances, to slowing the pace of enrichment, and to begin transforming high-enriched uranium into a powdered form unsuitable for use in weapons." Perhaps Iran and other countries, too, will come to understand that rejecting nuclear-weapons capability signals strength and confidence in an interconnected world.
That is above the 20 per cent enrichment level Iran has declared at the site, and takes it across the line from low-enriched to high-enriched uranium.

Under a deal proposed in May known as the Tehran Declaration, Iran would ship some low-enriched uranium to Turkey in return for 20 percent high-enriched uranium to be supplied at a later date for a Tehran research reactor.
Hailed by the three, the declaration stipulates Iran is ready to send 1,200 kilograms of its low-enriched uranium (LEU) to Turkey to be supplied at a later date with high-enriched uranium by Russia and France.
Turkey and Brazil voted against the sanctions after brokering a deal with Iran last month under which the Islamic Republic agreed to ship 1,200 kilograms of its low-enriched uranium abroad in return for high-enriched uranium fuel for a research reactor in Tehran.
