4 days ago · Plutonium is a chemical element; it has symbol Pu and atomic number 94. It is an actinide metal of silvery-gray appearance that tarnishes when exposed to air, and forms a dull coating when oxidized. The element normally exhibits six allotropes and four oxidation states.
May 21, 2024 · Plutonium (Pu), radioactive chemical element of the actinoid series of the periodic table, atomic number 94. It is the most important transuranium element because of its use as fuel in certain types of nuclear reactors and as an ingredient in nuclear weapons. Plutonium is a silvery metal that takes.
3 days ago · Trinity was the code name of the first detonation of a nuclear weapon, conducted by the United States Army at 5:29 a.m. MWT (11:29:21 GMT) on July 16, 1945, as part of the Manhattan Project. The test was of an implosion-design plutonium bomb, nicknamed the "gadget", of the same design as the Fat Man bomb later detonated over Nagasaki , Japan ...
May 15, 2024 · The photo is from April 2022. The Plutonium Uranium Extraction Plant (PUREX) was the fifth and final chemical processing facility built at Hanford. The plant operated from 1956 to 1972 and 1983 to 1988, to chemically process uranium fuel rods irradiated in Hanford’s reactors.
May 25, 2024 · World & Nation. Sites with radioactive material more vulnerable as climate change increases wildfire, flood risks. In February, wildfires came within three miles of the Pantex Plant in Panhandle,...
1 day ago · The second line of development pursued by the Manhattan Project used plutonium. Although small amounts of plutonium exist in nature, the best way to obtain large quantities is via a reactor. Natural uranium is bombarded by neutrons and transmuted into uranium-239, which rapidly decays, first into neptunium-239 and then into plutonium-239.
May 7, 2024 · The fissile material is enriched uranium or plutonium. The energy output of the reaction can range from the equivalent of about a ton of the explosive trinitrotoluene, or TNT, to as much as 500 kilotons of TNT. The bomb also releases radioactive fission fragments, which result from the heavy nuclei breaking into smaller ones.
