Now, plutonium, 10 to 13 pounds this. This is enough plutonium to create a Nagasaki size atomic weapon.

That you'd need 10 to 13 pounds of plutonium.

Maybe keep a few little bombs of plutonium on the side.

Ten reactors that had produced weapons grade plutonium have been shut down.

The nuclear materials in question are plutonium, uranium, thorium, deuterium, tritium and lithium 6.

He said, It's easier to denature plutonium than to denature the evil spirit of man.

The Chernobyl disaster contaminated the Belarusian territory with long lived caesium, strontium and plutonium radionuclides.

Chemical compounds including such material and plutonium in spent fuel elements also belong to this category.

This includes, in accordance with the IAEA definition, nuclear material that can be used for the manufacture of nuclear explosive devices without further adaptation or additional enrichment. This is plutonium containing less than 80 per cent plutonium 238, highly enriched uranium (HEU) and uranium 233.

This is the first time that the plutonium rich carbide fuel has been reprocessed anywhere in the world.

Specific concern was expressed about both the environmental and proliferation risks of plutonium reprocessing and nuclear materials shipments.

12. Supports continued efforts by the United States of America and the Russian Federation to implement the 1997 Agreement concerning Cooperation regarding Plutonium Production Reactors and the 2000 Agreement concerning the Management and Disposition of Plutonium Designated as No Longer Required for Defence Purposes and Related Cooperation

Now you might want to look at plutonium as another fissionable material that you might use in a bomb.

Plutonium produced at the remaining three reactors which generate heat and electricity has not been used for nuclear weapons since 1994.

An RTG is a device without moving parts that converts the heat from the decay of the radioisotope Plutonium 238 (Pu 238) into electricity.

Third, the States parties should improve control over proliferation of sensitive parts of the nuclear fuel cycle, specifically, activities involving uranium enrichment and plutonium separation.

Pyongyang violated its obligations under the Nuclear Non Proliferation Treaty by secretly reprocessing enough plutonium to produce two nuclear weapons in the early 1990 s. After it withdrew from a restraining agreement negotiated by the Clinton administration in 1994, it expelled International Atomic Energy Agency inspectors and began reprocessing spent fuel that could produce another six bombs worth of plutonium.

About 121 incidents were reported to the Agency in 2004, some of which involved weapons usable highly enriched uranium or plutonium being smuggled across national borders.

There are many, many sites where warheads are stored and, in fact, lots of sites where fissionable materials, like highly enriched uranium and plutonium, are absolutely not safe.

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.

From 1993 through 2006, the International Atomic Energy Agency documented 175 cases of nuclear theft, 18 of which involved highly enriched uranium or plutonium, the key ingredients to make a nuclear weapon.

Meanwhile, with the cooperation of Japan, for the first time, 20 kilograms of weapon grade plutonium, equivalent to two to three nuclear warheads, was successfully disposed of with the aid of advanced technology developed by Russian scientists.

For a number of years, I have advocated the consideration of multilateral approaches to the nuclear fuel cycle, so as to address challenges posed by proliferation sensitive operations such as those related to uranium enrichment and plutonium separation.

Every technically competent person knows that the paths to civilian nuclear power and to nuclear weapons are the same, except for a few last, comparatively simple steps. The hard part is obtaining the fissionable materials plutonium or highly enriched uranium.

The indigenously developed unique plutonium rich mixed carbide fuel used in the fast breeder test reactor (FBTR) has performed extremely well, having operated past a burn up of 148,000 megawatt day per tonne (MWd t) without a single fuel pin failure.

On 7 9 February 2005, in the spirit of the Group of Eight's Global Partnership, Switzerland organized a conference designed to facilitate the participation of interested States in the decommissioning of the Russian Federation's three remaining plutonium producing nuclear reactors.

For its part, after announcing the cessation of the production of plutonium and highly enriched uranium for nuclear weapons, France decided in February 1996 to close and dismantle its facilities for the production of such materials at Pierrelatte and Marcoule.

But uranium enrichment makes a lot of sense if you want a nuclear weapon indeed, for that purpose, enrichment is indispensable. Moreover, Iran is building a heavy water reactor, supposedly for research purposes, but which is also needed to build a plutonium bomb.

(iv) Commit themselves to expediting agreement on alternatives, consistent with the Treaty on the Non Proliferation of Nuclear Weapons principles of the right to peaceful uses and the obligations for non proliferation, to the acquisition of domestic uranium enrichment and plutonium separation facilities

We therefore believe that in order to prevent the proliferation of nuclear weapons it is crucial to strengthen the supervisory competencies of the IAEA and to control more effectively the stages in the nuclear fuel cycle that involve uranium enrichment and plutonium processing.

While some States Parties to the NPT with fuel cycle capabilities under IAEA full scope safeguards have been under extensive pressure and restrictions, non parties to the Treaty with unsafeguarded plutonium reprocessing facilities have free access to any nuclear technology and know how.

After consultation with his staff, Bush responded that, absent a plutonium extraction facility, US intelligence could not confirm that the plant comprised a nuclear weapons program. I told him Olmert I had decided on a diplomatic option backed by force to stop Syria, Bush writes.

Lastly, there should be better controls over operations involving uranium enrichment, plutonium reprocessing and the disposal of spent fuel and nuclear waste they were a veritable Achilles heel of the current non proliferation regime, and should be concentrated in a limited number of regional centres.

Approximately 44,000 sq. km (21 per cent of the country's surface area) is contaminated with caesium 137 21,000 sq. km (10 per cent of the surface area) is contaminated with strontium 90 and 4,000 sq. km (2 per cent of the surface area) is contaminated with plutonium isotopes.

The mere threat could have held the Syrian government hostage. Far more worrying, had Syrian engineers built a lab at the site, or in other rebel held territory, to extract plutonium from the reactor s spent fuel, the insurgents might even have found themselves with the ingredients of an atomic bomb.

Mistakes are not limited to reactor sites. Accidents at the Savannah River reprocessing plant released ten times as much radio iodine as the accident at Three Mile Island, and a fire at the Gulf United facility in New York in 1972 scattered an undisclosed amount of plutonium, forcing the plant to shut down permanently.

Promote timely agreements to prevent the spread of uranium enrichment and plutonium separation technologies and facilities that respect fully the right to the peaceful uses of nuclear energy, as set out in the Treaty on the Non Proliferation of Nuclear Weapons, including alternatives such as the provision of guaranteed nuclear fuel supplies

Second, while the access of non nuclear weapon States to the benefits of nuclear technology should not be curtailed, we should focus on creating incentives for States to voluntarily forego the development of domestic uranium enrichment and plutonium separation capacities, while guaranteeing their supply of the fuel necessary to develop peaceful uses.

On 2 April 2002 Uruguay was declared free of nuclear material by IAEA safeguards authorities who, on inspecting the Nuclear Research Centre, where a research reactor had been installed and subsequently dismantled, removed any remaining plutonium or enriched uranium (total fissionable uranium 235) and certified that Uruguay's inventory contained none of either element.

As mentioned in the first report, Section 152 a of the Penal Code makes it an offence to receive, possess, use, transfer, alter, dispose of or distribute any material consisting of or containing plutonium or uranium without lawful permission and thereby cause a risk of damage to any person's body, health, property or living environment.

Japan committed itself, for the purpose of the Partnership, to make a contribution amounting to a little more than 200 million United States dollars, of which 100 million is to be allocated to the G 8 disposition programme for Russian surplus weapon grade plutonium and the rest to projects for dismantling Russian decommissioned nuclear submarines.

I still recall the difficulty that I faced, as South Korea s foreign minister, in convincing Bush administration policymakers to negotiate with North Korea instead of merely applying pressure and waiting for the North to capitulate. Back then, North Korea was restarting its Yongbyon nuclear facility and producing plutonium, thus strengthening its bargaining position vis à vis the US.

In addition, a number of countries with nuclear energy programs have the capability, if they choose, to manufacture nuclear weapons within a matter of months if their security perceptions change, because they have mastered the critical technology uranium enrichment and plutonium reprocessing. If more countries take this path, it could prove to be the Achilles heel of non proliferation.

Six cases mark the most egregious cheating. Twice, Iraq bucked safeguards first when it built the Osirak reactor and failed to provide inspectors full transparency and convincing assurance it would not use the plant to produce plutonium for weapons, and, second, when it nearly completed its secret enrichment program prior to the 1991 Persian Gulf War.

The scope of the treaty should provide for a ban on future production of weapons grade uranium and plutonium for nuclear weapons purposes a ban on assistance in or encouragement of production of these materials by other States prohibition of the transfer of fissile material from the civilian to the military cycle for nuclear weapons purposes.
