name a few reactors that use this element
The X-10 Graphite Reactor,  Argonne National Laboratory's Experimental Breeder Reactor I, BORAX-III.
Uranium
The X-10 Graphite Reactor at Oak Ridge National Laboratory (ORNL) in Oak Ridge, Tennessee, formerly known as the Clinton Pile and X-10 Pile, was the world's second artificial nuclear reactor (after Enrico Fermi's Chicago Pile) and was the first reactor designed and built for continuous operation. Argonne National Laboratory's Experimental Breeder Reactor I, located at the Atomic Energy Commission's National Reactor Testing Station near Arco, Idaho, became the first nuclear reactor to create electricity on 20 December 1951. Initially, four 150-watt light bulbs were lit by the reactor, but improvements eventually enabled it to power the whole facility (later, the town of Arco became the first in the world to have all its electricity come from nuclear power generated by BORAX-III, another reactor designed and operated by Argonne National Laboratory). The world's first commercial scale nuclear power station, Obninsk in the Soviet Union, began generation with its reactor AM-1 on 27 June 195
where is uranium found and how abundant is it In nature and in and a very small amounts. how does it look? When refined, uranium is a silvery white, weakly radioactive metal. what military uses does it have? The major application of uranium in the military sector is in high-density penetrators. and civilian? The main use of uranium in the civilian sector is to fuel nuclear power plants. is it radioactive? Yes who discovered it? Martin Heinrich Klaproth. what kind of research is being done on it? Fission research. can it be used to make weapons? Yes. Two major types of atomic bombs were developed by the United States during World War II: a uranium-based device whose fissile material was highly enriched uranium. what is its origin? Along with all elements having atomic weights higher than that of iron, uranium is only naturally formed by the r-process in supernovae and neutron star mergers. what 'ph' effects does it have? When the pH of a uranium(VI) solution increases, the uranium is converted to a hydrated uranium oxide hydroxide and at high pHs it becomes an anionic hydroxide complex. how is it related to halides? All uranium fluorides are created using uranium tetrafluoride, itself is prepared by hydrofluorination of uranium dioxide. why is it enriched? For nuclear weapons and most nuclear power plants. what happens to people who are exposed to it? After entering the bloodstream, the absorbed uranium tends to bioaccumulate and stay for many years in bone tissue because of uranium's affinity for phosphates. what precautions need to be taken to prevent exposure? Uranium metal is commonly handled with gloves as a sufficient precaution. Uranium concentrate is handled and contained so as to ensure that people do not inhale or ingest it. what is its atomic number? Its atomic number is 92. how is it related to carbonates? The interactions of carbonate anions with uranium(VI) cause the Pourbaix diagram to change greatly when the medium is changed from water to a carbonate containing solution.
