The Treaty on the Non-Proliferation of Nuclear Weapons, commonly known as the Non-Proliferation Treaty or NPT, is an international treaty whose objective is to prevent the spread of nuclear weapons and weapons technology, to promote cooperation in the peaceful uses of nuclear energy, and to further the goal of achieving nuclear disarmament and general and complete disarmament. Between 1965 and 1968, the treaty was negotiated by the Eighteen Nation Committee on Disarmament, a United Nations-sponsored organization based in Geneva, Switzerland.
Nuclear proliferation is the spread of nuclear weapons, fissionable material, and weapons-applicable nuclear technology and information to nations not recognized as "Nuclear Weapon States" by the Treaty on the Non-Proliferation of Nuclear Weapons, commonly known as the Non-Proliferation Treaty or NPT. Proliferation has been opposed by many nations with and without nuclear weapons, as governments fear that more countries with nuclear weapons will increase the possibility of nuclear warfare, de-stabilize international or regional relations, or infringe upon the national sovereignty of nation states.
North Korea has a military nuclear weapons program and, as of 2024, is estimated to have an arsenal of approximately 50 nuclear weapons and sufficient production of fissile material for six to seven nuclear weapons per year. North Korea has also stockpiled a significant quantity of chemical and biological weapons. In 2003, North Korea withdrew from the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). Since 2006, the country has conducted six nuclear tests at increasing levels of expertise, prompting the imposition of sanctions.
Nuclear terrorism refers to any person or persons detonating a nuclear weapon as an act of terrorism. Nuclear terrorism outlines a broad category of possible terror incidents, ranging in feasibility and scope. Possible methods include the sabotage of a nuclear facility, the intentional irradiation of citizens, and/or the detonation of a radiological device, colloquially termed a dirty bomb, but consensus is lacking. According to the 2005 United Nations International Convention for the Suppression of Acts of Nuclear Terrorism. nuclear terrorism is an offense committed if a person unlawfully and intentionally "uses in any way radioactive material … with the intent to cause death or serious bodily injury; or with the intent to cause substantial damage to property or to the environment; or with the intent to compel a natural or legal person, an international organization or a State to do or refrain from doing an act."
The Baghdad Nuclear Research Facility adjacent to the Tuwaitha "Yellow Cake Factory" or Tuwaitha Nuclear Research Center contains the remains of nuclear reactors bombed by Iran in 1980, Israel in 1981, and the United States in 1991. It was used as a storage facility for spent reactor fuel and industrial and medical wastes. The radioactive material would not be useful for a fission bomb, but could be used in a dirty bomb. Following the 2003 invasion of Iraq, the facility was heavily looted by hundreds of Iraqis, though it is unclear what was taken.
Iran has research sites, two uranium mines, a research reactor, and uranium processing facilities that include three known uranium enrichment plants.
Pakistan is one of nine states that possess nuclear weapons. Pakistan began developing nuclear weapons in January 1972 under Prime Minister Zulfikar Ali Bhutto, who delegated the program to the Chairman of the Pakistan Atomic Energy Commission (PAEC) Munir Ahmad Khan with a commitment to having the device ready by the end of 1976. Since PAEC, which consisted of over twenty laboratories and projects under reactor physicist Munir Ahmad Khan, was falling behind schedule and having considerable difficulty producing fissile material, Abdul Qadeer Khan, a metallurgist working on centrifuge enrichment for Urenco, joined the program at the behest of the Bhutto administration by the end of 1974. Producing fissile material was pivotal to the Kahuta Project's success and thus to Pakistan obtaining the capability to detonate a nuclear weapon by the end of 1984.
During World War II, Japan had several programs exploring the use of nuclear fission for military technology, including nuclear reactors and nuclear weapons. Like the similar wartime programs in Nazi Germany, it was relatively small, suffered from an array of problems brought on by lack of resources and wartime disarray, and was ultimately unable to progress beyond the laboratory stage during the war.
South Korea has the raw materials and equipment to produce a nuclear weapon. However, it has not opted to make one. South Korea has continued on a stated policy of non-proliferation of nuclear weapons since 2004 and has adopted a policy to maintain a nuclear-free Korean Peninsula. South Korea also allows the United States to maintain nuclear weapons on its territories, which the US first brought to the peninsula in January 1958. North Korea has and is developing additional nuclear weapons.
The La Hague site is a nuclear fuel reprocessing plant at La Hague on the Cotentin Peninsula in northern France, with the Manche storage centre bordering on it. Operated by Orano, formerly AREVA, and prior to that COGEMA, La Hague has nearly half of the world's light water reactor spent nuclear fuel reprocessing capacity. It has been in operation since 1976, and has a capacity of about 1,700 tonnes per year. It extracts plutonium which is then recycled into MOX fuel at the Marcoule site.
Weapons-grade nuclear material is any fissionable nuclear material that is pure enough to make a nuclear weapon and has properties that make it particularly suitable for nuclear weapons use. Plutonium and uranium in grades normally used in nuclear weapons are the most common examples.
The Rokkasho Nuclear Fuel Reprocessing Facility is a nuclear reprocessing plant with an annual capacity of 800 tons of uranium or 8 tons of plutonium. It is owned by Japan Nuclear Fuel Limited (JNFL) and is part of the Rokkasho complex located in the village of Rokkasho in northeast Aomori Prefecture, on the Pacific coast of the northernmost part of Japan's main island of Honshu.
Libya pursued programs to develop or acquire weapons of mass destruction from when Muammar Gaddafi seized control of Libya in 1969 until he announced on 19 December 2003 that Libya would voluntarily eliminate all materials, equipment and programs that could lead to internationally proscribed weapons. This included weapons of mass destruction and long-range ballistic missiles.
The National Nuclear Security Administration (NNSA) is a United States federal agency responsible for safeguarding national security through the military application of nuclear science. NNSA maintains and enhances the safety, security, and effectiveness of the U.S. nuclear weapons stockpile; works to reduce the global danger from weapons of mass destruction; provides the United States Navy with safe and effective nuclear propulsion; and responds to nuclear and radiological emergencies in the United States and abroad.
Reprocessed uranium (RepU) is the uranium recovered from nuclear reprocessing, as done commercially in France, the UK and Japan and by nuclear weapons states' military plutonium production programs. This uranium makes up the bulk of the material separated during reprocessing.
The 2010 Nuclear Security Summit was a summit held in Washington, D.C., on April 12 and 13, 2010. The Summit focused on how to better safeguard weapons-grade plutonium and uranium to prevent nuclear terrorism.
The Nuclear Security Summit (NSS) was a semi-annual world summit, aimed at preventing nuclear terrorism around the globe. The first summit was held in Washington, D.C., United States, on April 12–13, 2010. The second summit was held in Seoul, South Korea, in 2012. The third summit was held in The Hague, Netherlands, on March 24–25, 2014. The fourth and final summit was held in Washington, D.C., on March 31–April 1, 2016.
Gift basket diplomacy is an approach to multilateral negotiation aimed at pushing forward progress on a particular issue without the requirement of consensus. The policy is most often seen in United Nations style diplomatic meetings where a particular group of countries wishes to take action or make a joint statement but is unable to do so without the consensus of all parties involved. Gift basket diplomacy fundamentally is collective action agreed by smaller groups of participants that goes beyond the lowest common denominator consensus that larger groups often reach in large multilateral fora. The United States first introduced Gift basket diplomacy in 2011 during the Nuclear Security Summit preparation process and more than 30 countries participated in fourteen Gift basket diplomacy statements at the 2012 Nuclear Security Summit in Seoul.
