When plutonium was first being produced in quantity during the Manhattan Project, no one really knew anything about it. One researcher, Donald Mastick, accidentally swallowed a small amount of plutonium chloride and it was detectable in his body for 30 years. From 1945 to 1947, 18 people were...
stable form from room temp to 115°C; enthalpy of vaporization 333.5kJ/mol; enthalpy of fusion 2.82kJ/mol; discovered in 1940–1941; prepared in ton quantities in nuclear reactors; 238Pu produced in kg amounts from 237Np; important fuel for producing power for terrestrial and extraterrestrial ...
Today, however, it is mostly used for creating energy throughout the world. In fact, over one-third of energy produced in most nuclear power plants comes from plutonium. Plutonium’s elements are found in naturally-occurring uranium ores, where it is formed by irradiation of natural uranium ...
The plutonium that will be produced in the nuclear fuel cycle is a matter of extreme importance to regulators and to members of the public concerned with the environment. At the present time there is plutonium present in the environment on a global scale from weapons testing and from a satelli...
Metallic plutonium is produced by reacting plutonium tetrafluoride with barium, calcium or lithium at 1200 °C.[28] It is attacked by acids, oxygen, and steam but not by alkalis and dissolves easily in concentrated hydrochloric, hydroiodic and perchloric acids.[29] Molten metal must be kept in...
"What is fascinating is that you find some six or 10 atoms which you can identify in the end as not from Earth but from space, and then you get some hints about where it had been produced and when it had been produced," Wallner said. The research was published today (May 13) in ...
The U.S. government plans to process its declared excess at the Energy Department's Savannah River Site, where much of its weapons plutonium was produced. In Russia, the plan is to store the material in a high-security facility being built at the Mayak plutonium complex in the Ural ...
The plutonium produced in the UK is unique, as it was produced from two different types of reactors. Magnox reactors were a creation of the UK's historic civil nuclear program. They produced plutonium isotopes less radioactive than the ones produced in the alternative Advanced Gas Reactors (AGR...

Uranium-238 is fissionable by fast neutrons, and is fertile, meaning it can be transmuted to fissile plutonium-239 in a nuclear reactor. Another fissile isotope, uranium-233, can be produced from natural thorium and is studied for future industrial use in nuclear technology.[citation needed] ...
