Nuclear power requires low enriched uranium as fuel. Enrich it further, in the same facilities, and you have bomb grade highly enriched uranium (HEU).

In order to produce plutonium the Israelis needed a large supply of uranium ore.

But, in the midst of those meetings, it was revealed that Iran has been secretly building a second enrichment facility with the potential to produce weapons grade uranium.

The film, produced by Shoko Hara and Paul Brenner, won the award for Best Animated Film at the International Uranium Film Festival in 2013.

President Bush now argues that all along it has been the above board enrichment of uranium, not some other, secret program, that carries Iran ever closer to having nuclear weapons.

Such non prohibited purposes should include, inter alia, the production and use of uranium as a fuel for power plants for sea going vessels, including submarines.

But months later, it is clear that the danger is not past, because Iran has not renounced the production of nuclear weapons, which its enriched uranium could eventually be used to fuel.

Uranium in the environment refers to the science of the sources, environmental behaviour, and effects of uranium on humans and other animals.

One, once headed by Dr. Khan, is responsible for producing bomb grade uranium gas that, when converted to metal, provides the crucial fuel for a nuclear explosion.

Proposals have been mooted to impose a moratorium on uranium enrichment and plutonium separation, to multilateralize the nuclear fuel cycle or to banish the building of new national fuel cycle facilities.

The participation of the largest possible number of States is vital first and foremost the nuclear Powers, but also countries which possess the potential to produce nuclear explosive devices and have uranium enrichment and spent fuel reprocessing facilities.

The uranium was seized in a sting operation.

The uranium was delivered in 1993.

Such uranium was the material of choice for terrorists.

The organ which is most affected is the kidney.

In nature, uranium is found as uranium 238 (99.2739 99.2752 ), uranium 235 (0.7198 0.7202 ), and a very small amount of uranium 234 (0.0050 0.0059 ).

Featured in these images is a new tunnel entrance near the Uranium Conversion Facility (UCF) at Esfahan and continued construction at the Natanz uranium enrichment site.

Iran responded to the demand to stop enrichment of uranium 24 August 2006, offering to return to the negotiation table but refusing to end enrichment.

On 9 April 2007, Iran announced that it has begun enriching uranium with 3 000 centrifuges, presumably at Natanz enrichment site.

The Uranium Enrichment Technology (Prohibition on Disclosure) Regulations 2004 make it an offence to make an unauthorised disclosure of uranium enrichment technology.

It has a smaller critical mass than uranium.

In most of these cases, however, low enriched uranium (LEU) can be substituted for HEU, or other techniques can be applied to achieve the required results.

Encouraged by the rich uranium deposits the Namibian government plans to erect its first nuclear power station by 2018, also uranium enrichment is envisaged to happen locally.

Indeed, Iran may already be enriching uranium secretly.

Because of its uranium content, the mineral is radioactive.

Agreement on the supply and leasing of enriched uranium and the transfer of equipment and special nuclear materials

Uranium enrichment is certainly the first condition for making bombs, but the level of enrichment must reach about 95 , compared to 3.5 for energy production.

LEU cannot be used to make weapons.

This feature is available only to nations with a great wealth of fissile uranium.

We have scant information about this, beyond some limited information about international acquisitions and some detection of traces of highly enriched uranium (HEU) on materials brought out of North Korea. If North Korea is using HEU in its bomb design, we have little knowledge about where it comes from and how much of it they have, or could have in the future.

Uranium is a chemical element with symbol U and atomic number 92.

This is of crucial importance to us, as our uranium resources are modest.

One example was the announcement that some of its enriched uranium is being diverted to medical research in other words, uranium enrichment, according to this message, can be slowed down.

Qadaffi exploited a network of opportunity. French controlled mines in Niger provided uranium ore. An undisclosed country conveyed a pilot uranium conversion facility.

According to the International Atomic Energy Agency (IAEA), Iran began enriching uranium at a pilot centrifuge plant last August, and is constructing larger underground enrichment facilities.

First, Iran must halt all enrichment of uranium to 20 purity (a level required for research reactors, but only a short step away, in practical terms, from weapons grade uranium).

An ensuing arms race during the Cold War between the United States and the Soviet Union produced tens of thousands of nuclear weapons that used uranium metal and uranium derived plutonium 239.

Police seize 2 tons of uranium in Sopocachi, La Paz, on August 28.

Canada also exports significant amounts of uranium and coal to Asia, Europe and Latin America.

Weapons grade uranium has not been produced in our country since 1989.

In 1970, Mexico's national institute for nuclear research successfully refined weapons grade uranium which is used in the manufacture of nuclear weapons but in April 2010, Mexico agreed to turn over its weapons grade uranium to the United States.

Bio fuel subsidies, which have encouraged the shift of land from producing food into energy, must be repealed.

It also had to verify the origin of the enriched uranium particles found at a number of locations, and find out how the Islamic Republic of Iran had come into possession of a P 2 uranium enrichment centrifuge technology.

An international co production is a production where two or more different production companies are working together, for example in a film production.
