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

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.
The assemblies will secure the reactor future by allowing conversion of the reactor from high-enriched uranium (HEU) to LEU use.
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.
Iran, Turkey and Brazil signed Tehran declaration on May 17, stipulates that Tehran send 1,200 kg of its low-enriched uranium (LEU) to Turkey in return for 20 percent high-enriched uranium to be supplied at a later date, the measure was shortly followed by the UN Security Council resolution against Iran early June.
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.
Obama achieved a number of important agreements designed to destroy or secure nuclear materials, including the signing of a protocol with Russia mandating the mutual elimination of "excess weapons-grade plutonium from defence programmes" and a commitment from Ukraine and Canada to dispose of high-enriched uranium.
11 celebrations come as the simmering dispute with world powers over Iran's nuclear program approaches boiling point after the Islamic republic on Tuesday defiantly began work on high-enriched uranium.
Estimates vary, but proliferation experts say 1,000-1,700 kg of low-enriched uranium, if converted into high-enriched uranium, would be enough to make a bomb.
David Albright of Institute for Science and International Security, a Washington think tank that tracks proliferation issues, said Iran now had accumulated enough LEU to convert into high-enriched uranium (HEU) sufficient for one atom bomb.
