A scientist carefully handles a plutonium sample in a secure laboratory.

Definition
  1. Noun:
    • A radioactive metallic chemical element: "Plutonium" is a dense, silvery-gray, artificially produced radioactive element. It is classified as a transuranic element, meaning its atomic number is higher than that of uranium. It is primarily known for its use in nuclear reactors and nuclear weapons due to its fissile properties.
Usage Examples
  • Noun:
    • The reactor core contains both uranium and plutonium.
    • Plutonium-239 is a key isotope for nuclear energy production.
    • Handling plutonium requires extreme safety precautions due to its radioactivity.
Advanced Usage

  • "Weapons-grade plutonium": Plutonium that has a high concentration of the isotope Pu-239, suitable for use in nuclear weapons.

    • The treaty aimed to reduce stockpiles of weapons-grade plutonium.

  • "Plutonium pit": The core component of a nuclear weapon's primary stage, made of plutonium.

    • The facility was responsible for manufacturing plutonium pits.
Variants and Related Words
  • Plutoniferous (adj): Containing or yielding plutonium. (Technical term)
  • Transuranic element (n): Any element with an atomic number greater than 92 (uranium). Plutonium is one such element.
Synonyms
  • Pu: The chemical symbol for plutonium.
  • Element 94: Refers to plutonium's atomic number.
Related Phrases

  • "Plutonium separation": The process of chemically isolating plutonium from spent nuclear fuel or other materials.

    • The reprocessing plant specializes in plutonium separation.

  • "Plutonium dioxide" (PuO₂): A common compound form of plutonium, often used as a nuclear fuel.

    • The mixed oxide (MOX) fuel contains plutonium dioxide.
Related Terminology

  • "Plutonium economy": A hypothetical or historical concept regarding a nuclear fuel cycle based on the reprocessing and reuse of plutonium.

    • Debates about the safety of a plutonium economy have persisted for decades.

  • "Plutonium disposition": The management and final disposal of surplus plutonium, especially from dismantled weapons.

    • The international agreement focused on plutonium disposition.
