  2. Plutonium-239 - Wikipedia

    en.wikipedia.org/wiki/Plutonium-239

    Plutonium-239 present in reactor fuel can absorb neutrons and fission just as uranium-235 can. Since plutonium-239 is constantly being created in the reactor core during operation, the use of plutonium-239 as nuclear fuel in power plants can occur without reprocessing of spent fuel; the plutonium-239 is fissioned in the same fuel rods in which ...

  3. Reactor-grade plutonium - Wikipedia

    en.wikipedia.org/wiki/Reactor-grade_plutonium

    Reactor-grade plutonium (RGPu) [1] [2] is the isotopic grade of plutonium that is found in spent nuclear fuel after the uranium-235 primary fuel that a nuclear power reactor uses has burnt up. The uranium-238 from which most of the plutonium isotopes derive by neutron capture is found along with the U-235 in the low enriched uranium fuel of ...

    Small traces of plutonium-239, a few parts per trillion, and its decay products are naturally found in some concentrated ores of uranium, [54] such as the natural nuclear fission reactor in Oklo, Gabon. [55] The ratio of plutonium-239 to uranium at the Cigar Lake Mine uranium deposit ranges from 2.4 × 10 −12 to 44 × 10 −12. [56]

    Anxiety medications. Anxiety medications called benzodiazepines like alprazolam (Xanax®) , diazepam (Valium®), and clonazepam (Klonopin®) can be used to quickly reduce anxiety attack symptoms.

  6. Weapons-grade nuclear material - Wikipedia

    en.wikipedia.org/wiki/Weapons-grade_nuclear_material

    Weapons-grade plutonium is defined as being predominantly Pu-239, typically about 93% Pu-239. [24] Pu-240 is produced when Pu-239 absorbs an additional neutron and fails to fission. Pu-240 and Pu-239 are not separated by reprocessing. Pu-240 has a high rate of spontaneous fission, which can cause a nuclear weapon to pre-detonate.

  7. Anxiolytic - Wikipedia

    en.wikipedia.org/wiki/Anxiolytic

    An anxiolytic (/ ˌ æ ŋ k s i ə ˈ l ɪ t ɪ k, ˌ æ ŋ k s i oʊ-/; also antipanic or anti-anxiety agent) [1] is a medication or other intervention that reduces anxiety. This effect is in contrast to anxiogenic agents which increase anxiety.

    Allegations that Silkwood's exposure to plutonium-239 was a deliberate act of radiation poisoning are fueled by the fact that she was in possession of potentially compromising evidence that linked Kerr-McGee with egregious safety violations, encompassing unsafe workplace conditions at the plant, faulty manufacture of fuel rod components that ...

  9. Plutonium-240 - Wikipedia

    en.wikipedia.org/wiki/Plutonium-240

    Plutonium-240 (240 Pu or Pu-240) is an isotope of plutonium formed when plutonium-239 captures a neutron.The detection of its spontaneous fission led to its discovery in 1944 at Los Alamos and had important consequences for the Manhattan Project.
