    en.wikipedia.org/wiki/Weapons-grade_nuclear_material

    To reduce the concentration of Pu-240 in the plutonium produced, weapons program plutonium production reactors (e.g. B Reactor) irradiate the uranium for a far shorter time than is normal for a nuclear power reactor. More precisely, weapons-grade plutonium is obtained from uranium irradiated to a low burnup.

  3. Plutonium (IV) oxide - Wikipedia

    en.wikipedia.org/wiki/Plutonium(IV)_oxide

    Plutonium(IV) oxide, or plutonia, is a chemical compound with the formula Pu O 2. This high melting-point solid is a principal compound of plutonium . It can vary in color from yellow to olive green, depending on the particle size, temperature and method of production.

  4. Plutonium - Wikipedia

    en.wikipedia.org/wiki/Plutonium

    When inhaled, plutonium can pass into the bloodstream. Once in the bloodstream, plutonium moves throughout the body and into the bones, liver, or other body organs. Plutonium that reaches body organs generally stays in the body for decades and continues to expose the surrounding tissue to radiation and thus may cause cancer. [148]

    Apr. 14—It's been almost 80 years since the first atomic bomb was detonated, and scientists say there's still much to learn about how nuclear devices function as they reach the point of exploding.

  6. Isotope separation - Wikipedia

    en.wikipedia.org/wiki/Isotope_separation

    Plutonium-based weapons use plutonium produced in a nuclear reactor, which must be operated in such a way as to produce plutonium already of suitable isotopic mix or grade. While chemical elements can be purified through chemical processes , isotopes of the same element have nearly identical chemical properties which makes this type of ...

    U will inevitably be enriched slightly stronger than 235 U, which is a negligible effect in a once-through fuel cycle due to the low (55 ppm) share of 234 U in natural uranium but can become relevant after successive passes through an enrichment-burnup-reprocessing-enrichment cycle, depending on enrichment and burnup characteristics. 234

    Joseph G. Hamilton was the primary researcher for the human plutonium experiments done at U.C. San Francisco from 1944 to 1947. [1] Hamilton wrote a memo in 1950 discouraging further human experiments because the AEC would be left open "to considerable criticism," since the experiments as proposed had "a little of the Buchenwald touch."
