weapons plutonium
Noun A specific, weapons-grade form of the radioactive element plutonium, specifically the isotope plutonium-239, which is the primary fissile material used in nuclear weapons. This term explicitly refers to plutonium that has been recovered from dismantled nuclear weapons and is typically stored in the weapon's original core components.
The term "weapons plutonium" is used in technical, political, and arms control contexts to specifically denote plutonium of a quality and origin suitable for use in nuclear weapons, particularly material that is no longer in an assembled weapon but poses a proliferation risk.
- The treaty focused on the secure storage and eventual disposal of weapons plutonium from decommissioned warheads.
- Scientists analyzed the sample to confirm it was weapons plutonium and not material from a civilian nuclear reactor.
- The safe management of weapons plutonium is a critical international security issue.
The term is often used in discussions concerning: * Nuclear disarmament: The process of reducing or eliminating nuclear arsenals, which generates this material. * Non-proliferation: Efforts to prevent the spread of nuclear weapons and weapons-usable material. * Materials security: The physical protection and accounting of this hazardous substance to prevent theft or diversion.
- Weapons-grade plutonium: A closely related term emphasizing the quality (high concentration of Pu-239) of the material rather than its specific origin from dismantled weapons. All "weapons plutonium" is "weapons-grade," but not all "weapons-grade plutonium" necessarily comes from a dismantled weapon.
- Reactor-grade plutonium: Plutonium produced in a civilian nuclear power reactor, which typically has a different isotopic composition and is less ideal for efficient weapon design.
- Plutonium pit: The core component of a nuclear weapon where the plutonium is stored; "weapons plutonium" is often stored in these pits after a weapon is taken apart.
- Fissile material (in this specific context)
- Weapons-usable plutonium
The term carries significant political and technical weight. It distinguishes this material from other forms of plutonium (e.g., from civilian nuclear fuel cycles) and underscores its direct connection to nuclear weapons programs, making its handling and disposal a matter of global security.
-
plutonium 239 that is recovered when nuclear weapons are disassembled; it is stored in plutonium pits
