Terms and Definitions
A nuclear warhead is a type of weapon that uses nuclear reactions to generate destructive force. It can be launched from aircraft, submarines, surface ships, or even from ground installations. Upon detonation, these warheads release energy in the form of an intense light pulse, a shock wave, heat and deadly radiation.
An atomic bomb is a weapon that uses nuclear fission to release energy in a single, sudden burst. Atomic bombs were the first nuclear weapons to be developed and are the type that was used in the bombings of Hiroshima and Nagasaki during World War II.
Also known as a thermonuclear bomb, a hydrogen bomb is a more advanced and powerful type of nuclear weapon. It uses nuclear fusion to release a substantial amount of energy. This process involves fusing isotopes of hydrogen, hence the name. It's significantly more powerful than atomic bombs, which rely solely on fission.
Nuclear stockpile refers to the collection of nuclear warheads that a country has stored. This includes weapons that are active and ready to use, those being held in reserve, and any weapon components that can be used to assemble additional warheads.
The nuclear arms race is a term used to describe the cold war competition between superpowers, specifically the US and the USSR, to build up the largest and most powerful arsenal of nuclear weapons. This period witnessed a rapid increase in the quantity and quality of nuclear weapons on a global scale.
Deterrence theory is the idea in international relations that nuclear weapons are intended to deter other states from starting a conflict, due to the mutual assured destruction that would result. In a nuclear context, it asserts that nuclear weapons provide strategic stability and prevent war through balance of power.
The Non-Proliferation Treaty is an international treaty whose objective is to prevent the spread of nuclear weapons and weapons technology while promoting cooperation in the peaceful uses of nuclear energy. It acknowledges the right of all nations to access and use nuclear energy for peaceful purposes.
Decommissioning refers to the process of retiring a nuclear warhead from active service. This involves safely dismantling the warhead, disposing of any fissile material in a manner that it cannot be used for weapons again, and dealing with any radiological hazards.
Fissile materials are isotopes capable of sustaining a nuclear chain reaction. They are used as fuel in nuclear reactors and as the explosive material in nuclear weapons. Examples include Uranium-235, Uranium-233 and Plutonium-239.
