- WMD (weapons of mass destruction)
- WMD: Typically refers to nuclear, biological, or chemical weapons, though there is some debate as to whether chemical weapons qualify as weapons of “mass destruction.”
- Nonproliferation
- Nonproliferation: Measures to prevent the spread of biological, chemical, and/or nuclear weapons and their delivery systems. See entry for Proliferation.
- Treaty on the Non-Proliferation of Nuclear Weapons (NPT)
- The NPT: Signed in 1968, the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) is the most widely adhered-to international security agreement. The “three pillars” of the NPT are nuclear disarmament, nonproliferation, and peaceful uses of nuclear energy. Article VI of the NPT commits states possessing nuclear weapons to negotiate in good faith toward halting the arms race and the complete elimination of nuclear weapons. The Treaty stipulates that non-nuclear-weapon states will not seek to acquire nuclear weapons, and will accept International Atomic Energy Agency safeguards on their nuclear activities, while nuclear weapon states commit not to transfer nuclear weapons to other states. All states have a right to the peaceful use of nuclear energy, and should assist one another in its development. The NPT provides for conferences of member states to review treaty implementation at five-year intervals. Initially of a 25-year duration, the NPT was extended indefinitely in 1995. For additional information, see the NPT.
- Additional Protocol
- The Additional Protocol is a legal document granting the International Atomic Energy Agency (IAEA) complementary inspection authority to that provided in underlying safeguards agreements. The principal aim is to enable the IAEA inspectorate to provide assurance about both declared and possible undeclared activities. Under the Protocol, the IAEA is granted expanded rights of access to information and sites, as well as additional authority to use the most advanced technologies during the verification process. See entry for Information Circular 540.
- International Atomic Energy Agency (IAEA)
- IAEA: Founded in 1957 and based in Vienna, Austria, the IAEA is an autonomous international organization in the United Nations system. The Agency’s mandate is the promotion of peaceful uses of nuclear energy, technical assistance in this area, and verification that nuclear materials and technology stay in peaceful use. Article III of the Nuclear Non-Proliferation Treaty (NPT) requires non-nuclear weapon states party to the NPT to accept safeguards administered by the IAEA. The IAEA consists of three principal organs: the General Conference (of member states); the Board of Governors; and the Secretariat. For additional information, see the IAEA.
- Ratification
- Ratification: The implementation of the formal process established by a country to legally bind its government to a treaty, such as approval by a parliament. In the United States, treaty ratification requires approval by the president after he or she has received the advice and consent of two-thirds of the Senate. Following ratification, a country submits the requisite legal instrument to the treaty’s depository governments Procedures to ratify a treaty follow its signature.
See entries for Entry into force and Signature.
- Comprehensive Nuclear-Test-Ban Treaty (CTBT)
- The CTBT: Opened for signature in 1996 at the UN General Assembly, the CTBT prohibits all nuclear testing if it enters into force. The treaty establishes the Comprehensive Test Ban Treaty Organization (CTBTO) to ensure the implementation of its provisions and verify compliance through a global monitoring system upon entry into force. Pending the treaty’s entry into force, the Preparatory Commission of the CTBTO is charged with establishing the International Monitoring System (IMS) and promoting treaty ratifications. CTBT entry into force is contingent on ratification by 44 Annex II states. For additional information, see the CTBT.
- Fissile material
- Fissile material: A type of fissionable material capable of sustaining a chain reaction by undergoing fission upon the absorption of low-energy (or thermal) neutrons. Uranium-235, Plutonium-239, and Uranium-233 are the most prominently discussed fissile materials for peaceful and nuclear weapons purposes.
- Nuclear power plant
- Nuclear power plant: A facility that generates electricity using a nuclear reactor as its heat source to provide steam to a turbine generator.
- Critical
- Critical: A state where the number of neutrons in each period of time, or generation, remains constant. When a nuclear reactor is “steady-state,” or operating at normal power levels for extended periods of time, it is in this state.
- Nuclear power plant
- Nuclear power plant: A facility that generates electricity using a nuclear reactor as its heat source to provide steam to a turbine generator.
- United Nations Security Council
- United Nations Security Council: Under the United Nations Charter, the Security Council has primary responsibility for maintaining international peace and security. The Council consists of fifteen members, five of which—China, France, Russia, the United Kingdom, and the United States—are permanent members. The other ten members are elected by the General Assembly for two-year terms. The five permanent members possess veto powers. For additional information, see the UNSC.
- Spent nuclear fuel
- Spent nuclear fuel: Irradiated nuclear fuel. Once irradiated, nuclear fuel is highly radioactive and extremely physically hot, necessitating special remote handling. Fuel is considered “self protecting” if it is sufficiently radioactive that those who might seek to divert it would not be able to handle it directly without suffering acute radiation exposure.
- CIS
- The Commonwealth of Independent States (CIS) is an association of former Soviet states that coordinates the facilitation of free movement of goods, services, labor force, and capital among member states and promotes cooperation on security matters.
- Export control
- National laws or international arrangements established to restrict the sale of certain goods to certain countries, or to ensure that safeguards or end-use guarantees are applied to the export and sale of sensitive and dual-use technologies and materials. See entry for Dual-use
- Bilateral
- Bilateral: Negotiations, arrangements, agreements, or treaties that affect or are between two parties—and generally two countries.
- Radioactivity
- Radioactivity: The spontaneous emission of radiation, generally alpha or beta particles, often accompanied by gamma rays, from the nucleus of an unstable isotope.
- (Nuclear) Forensics
- (Nuclear) Forensics: Refers to the process of investigating the origin of nuclear material, for example in nuclear materials trafficking cases. For a related concept, see attribution.
- Biological and Toxin Weapons Convention (BTWC)
- The BTWC: The Convention on the Prohibition of the Development, Production and Stockpiling of Bacteriological (Biological) and Toxin Weapons and on Their Destruction (BTWC) prohibits the development, production, or stockpiling of bacteriological and toxin weapons. Countries must destroy or divert to peaceful purposes all agents, toxins, weapons, equipment, and means of delivery within nine months after the entry into force of the convention. The BTWC was opened for signature on April 10, 1972, and entered into force on March 26, 1975. In 1994, the BTWC member states created the Ad Hoc Group to negotiate a legally binding BTWC Protocol that would help deter violations of the BTWC. The draft protocol outlines a monitoring regime that would require declarations of dual-use activities and facilities, routine visits to declared facilities, and short-notice challenge investigations. For additional information, see the BTWC.
- Biological weapon (BW)
- Biological weapons use microorganisms and natural toxins to produce disease in humans, animals, or plants. Biological weapons can be derived from: bacteria (anthrax, plague, tularemia); viruses (smallpox, viral hemorrhagic fevers); rickettsia (Q fever and epidemic typhus); biological toxins (botulinum toxin, staphylococcus enterotoxin B); and fungi (San Joaquin Valley fever, mycotoxins). These agents can be deployed as biological weapons when paired with a delivery system, such as a missile or aerosol device.
- Pathogen
- Pathogen: A microorganism capable of causing disease.
- Ballistic missile
- A delivery vehicle powered by a liquid or solid fueled rocket that primarily travels in a ballistic (free-fall) trajectory. The flight of a ballistic missile includes three phases: 1) boost phase, where the rocket generates thrust to launch the missile into flight; 2) midcourse phase, where the missile coasts in an arc under the influence of gravity; and 3) terminal phase, in which the missile descends towards its target. Ballistic missiles can be characterized by three key parameters - range, payload, and Circular Error Probable (CEP), or targeting precision. Ballistic missiles are primarily intended for use against ground targets.
- North Atlantic Treaty Organization (NATO)
- The North Atlantic Treaty Organization is a military alliance that was formed in 1949 to help deter the Soviet Union from attacking Europe. The Alliance is based on the North Atlantic Treaty, which was signed in Washington on 4 April 1949. The treaty originally created an alliance of 10 European and two North American independent states, but today NATO has 28 members who have committed to maintaining and developing their defense capabilities, to consulting on issues of mutual security concern, and to the principle of collective self-defense. NATO is also engaged in out-of-area security operations, most notably in Afghanistan, where Alliance forces operate alongside other non-NATO countries as part of the International Security Assistance Force (ISAF). For additional information, see NATO.
- Scud
- Scud is the designation for a series of short-range ballistic missiles developed by the Soviet Union in the 1950s and transferred to many other countries. Most theater ballistic missiles developed and deployed in countries of proliferation concern, for example Iran and North Korea, are based on the Scud design.
- Tactical nuclear weapons
- Short-range nuclear weapons, such as artillery shells, bombs, and short-range missiles, deployed for use in battlefield operations.
- Ballistic missile

- The CW: The Organization for the Prohibition of Chemical Weapons defines a chemical weapon as any of the following: 1) a toxic chemical or its precursors; 2) a munition specifically designed to deliver a toxic chemical; or 3) any equipment specifically designed for use with toxic chemicals or munitions. Toxic chemical agents are gaseous, liquid, or solid chemical substances that use their toxic properties to cause death or severe harm to humans, animals, and/or plants. Chemical weapons include blister, nerve, choking, and blood agents, as well as non-lethal incapacitating agents and riot-control agents. Historically, chemical weapons have been the most widely used and widely proliferated weapon of mass destruction.
- Geneva Protocol
- Geneva Protocol: Formally known as the Protocol for the Prohibition of the Use in War of Asphyxiating, Poisonous or Other Gases, and of Bacteriological Methods of Warfare, this protocol prohibits the use in war of asphyxiating, poisonous, or other gases, and bans bacteriological warfare. It was opened for signature on 17 June 1925. For additional information, see the Geneva Protocol.
