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.
The Agreed Framework between the United States of America and the Democratic People's Republic of Korea (북미제네바기본합의서) was signed on 21 October 1994, between North Korea (DPRK) and the United States. The objective of the agreement was the freezing and replacement of North Korea's indigenous nuclear power plant program with more nuclear proliferation resistant light water reactor power plants, and the step-by-step normalization of relations between the U.S. and the DPRK. Implementation of the agreement was troubled from the start, but its key elements were being implemented until it effectively broke down in 2003.
The Nyongbyon Nuclear Scientific Research Center (녕변원자력연구소) is North Korea's major nuclear facility, operating its first nuclear reactors. It is located in Nyongbyon County in North Pyongan Province, about 100 km north of Pyongyang. The center produced the fissile material for North Korea's six nuclear weapon tests from 2006 to 2017, and since 2009 is developing indigenous light water reactor nuclear power station technology.
Iran has research sites, two uranium mines, a research reactor, and uranium processing facilities that include three known uranium enrichment plants.
Iran is not known to currently possess weapons of mass destruction (WMD) and has signed treaties repudiating the possession of WMD including the Biological Weapons Convention, the Chemical Weapons Convention, and the Non-Proliferation Treaty (NPT). Iran has first-hand knowledge of WMD effects—over 100,000 Iranian troops and civilians were victims of chemical weapons during the 1980s Iran–Iraq War.
Nuclear material refers to the metals uranium, plutonium, and thorium, in any form, according to the IAEA. This is differentiated further into "source material", consisting of natural and depleted uranium, and "special fissionable material", consisting of enriched uranium (U-235), uranium-233, and plutonium-239. Uranium ore concentrates are considered to be a "source material", although these are not subject to safeguards under the Nuclear Non-Proliferation Treaty.
The Megatons to Megawatts Program, also called the United States-Russia Highly Enriched Uranium Purchase Agreement, was an agreement between Russia and the United States whereby Russia converted 500 metric tons of "excess" weapons-grade uranium into 15,000 metric tons of low enriched uranium, which was purchased by the US for use in its commercial nuclear power plants. The official name of the program is the "Agreement between the Government of the Russian Federation and the Government of the United States of America Concerning the Disposition of Highly-Enriched Uranium Extracted from Nuclear Weapons", dated February 18, 1993. Under this Agreement, Russia agreed to supply the United States with low-enriched uranium (LEU) obtained from high-enriched uranium (HEU) found to be in excess of Russian defense purposes. The United States agreed to purchase the low-enriched uranium fuel.
A nuclear fuel bank is reserve of low enriched uranium (LEU) for countries that need a backup source of LEU to fuel their nuclear reactors. Countries that do have enrichment technology would donate enriched fuel to a "bank", from which countries not possessing enrichment technology would obtain fuel for their power reactors.
This is the timeline of the nuclear program of Iran.
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.
Nuclear Fuel Services Inc. (NFS) is an American company that has been a major supplier of fuel for the United States Navy's fleet of nuclear-powered vessels since the 1960s. In recent years it has also reprocessed weapons-grade uranium into nuclear reactor fuel. It operates a 65-acre (260,000 m2) gated complex in Erwin, Tennessee. NFS's original facility was based in Ashford, New York from 1964 to 1972, a site now known as the West Valley Demonstration Project. NFS is a subsidiary of BWX Technologies, Inc.
Iran's nuclear program is made up of a number of nuclear facilities, including nuclear reactors and various nuclear fuel cycle facilities.
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.
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 2012 Nuclear Security Summit was a summit held at the COEX Convention & Exhibition Center in Seoul, South Korea, on March 26 and 27, 2012. It was the second time the conference was held after the 2010 Nuclear Security Summit.
The 2014 Nuclear Security Summit was a summit held in The Hague, the Netherlands, on March 24 and 25, 2014. It was the third edition of the conference, succeeding the 2012 Nuclear Security Summit. The 2014 summit was attended by 58 world leaders, some 5,000 delegates and some 3,000 journalists. The representatives attending the summit included US President Barack Obama and Chinese President Xi Jinping.
