The International Atomic Energy Agency (IAEA) is an intergovernmental organization that seeks to promote the peaceful use of nuclear energy and to inhibit its use for any military purpose, including nuclear weapons. It was established in 1957 as an autonomous organization within the United Nations system; though governed by its own founding treaty, the organization reports to both the General Assembly and the Security Council of the United Nations, and is headquartered at the UN Office at Vienna, Austria.
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.
A dirty bomb or radiological dispersal device is a radiological weapon that combines radioactive material with conventional explosives. The purpose of the weapon is to contaminate the area around the dispersal agent/conventional explosion with radioactive material, serving primarily as an area denial device against civilians. It is not to be confused with a nuclear explosion, such as a fission bomb, which produces blast effects far in excess of what is achievable by the use of conventional explosives. Unlike the cloud of radiation from a typical fission bomb, a dirty bomb's radiation can be dispersed only within a few hundred meters or a few miles of the explosion.
Nuclear terrorism refers to any person or persons detonating a nuclear weapon as an act of terrorism. Some definitions of nuclear terrorism include the sabotage of a nuclear facility and/or the detonation of a radiological device, colloquially termed a dirty bomb, but consensus is lacking. In legal terms, 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", according to the 2005 United Nations International Convention for the Suppression of Acts of Nuclear Terrorism.
A nuclear and radiation accident is defined by the International Atomic Energy Agency (IAEA) as "an event that has led to significant consequences to people, the environment or the facility." Examples include lethal effects to individuals, large radioactivity release to the environment, reactor core melt." The prime example of a "major nuclear accident" is one in which a reactor core is damaged and significant amounts of radioactive isotopes are released, such as in the Chernobyl disaster in 1986 and Fukushima nuclear disaster in 2011.
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.
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. By contrast, North Korea has and is developing additional nuclear weapons.
The United States and the Republic of Kazakhstan established diplomatic relations on December 16, 1991. The United States opened its embassy in Almaty in January 1992 and then relocated to Astana in 2006.
United Nations Security Council resolution 1540 was adopted unanimously on 28 April 2004 regarding the non-proliferation of weapons of mass destruction. The resolution establishes the obligations under Chapter VII of the United Nations Charter for all member states to develop and enforce appropriate legal and regulatory measures against the proliferation of chemical, biological, radiological, and nuclear weapons and their means of delivery, in particular, to prevent the spread of weapons of mass destruction to non-state actors.
The Global Initiative to Combat Nuclear Terrorism (GICNT) is an international organization consisting of 89 countries that have endorsed a set of nuclear security principles for nuclear terrorism deterrence, prevention, detection, and response. It is co-chaired by the United States and Russia. The organization aims to develop partnership capacity to combat nuclear terrorism, consistent with national legal authorities and obligations as well as relevant international legal frameworks such as the Convention for the Suppression of Acts of Nuclear Terrorism, the Convention on the Physical Protection of Nuclear Material, and United Nations Security Council Resolutions 1373 and 1540.
Iran convened a conference titled "International Disarmament and Non-proliferation: World Security without Weapons of Mass Destruction" on 17 and 18 April 2010 in Tehran. The theme of the conference was Nuclear Energy for All, Nuclear Weapons for No One.
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 2010 Review Conference for the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) was held at United Nations Headquarters in New York City from 3 to 28 May 2010. The President of the Review Conference is Ambassador Libran N. Cabactulan of the Philippines. UN Secretary-General Ban Ki-moon used the opening of the conference to note that "sixty five years later, the world still lives under the nuclear shadow".
The Nuclear Security Summit (NSS) is a 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 summit was held in Washington, D.C., on March 31–April 1, 2016
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.
Nuclear Non-Proliferation Act of 1978, 22 U.S.C. § 3201, is a United States federal law declaring that nuclear explosive devices pose a perilous threat to the security interests of the United States. The law restricts U.S. export of civil nuclear programs to other states.
The vulnerability of nuclear plants to deliberate attack is of concern in the area of nuclear safety and security. Nuclear power plants, civilian research reactors, certain naval fuel facilities, uranium enrichment plants, fuel fabrication plants, and even potentially uranium mines are vulnerable to attacks which could lead to widespread radioactive contamination. The attack threat is of several general types: commando-like ground-based attacks on equipment which if disabled could lead to a reactor core meltdown or widespread dispersal of radioactivity; external attacks such as an aircraft crash into a reactor complex, or cyber attacks.
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.
Material unaccounted for (MUF), in the context of nuclear material, refers to any discrepancy between a nuclear-weapons state's physical inventory of nuclear material, and the book inventory. The difference can be either a positive discrepancy or a negative discrepancy. Nuclear accounting discrepancies are commonplace and inevitable due to the problem of accurately measuring nuclear materials. This problem of inaccurate measurement provides a potential loophole for diversion of nuclear materials for weapons production. In a large plant, even a tiny percentage of the annual through-put of nuclear material will suffice to build one or more nuclear weapons.
