239 Pu has a higher probability for fission than 235 U and a larger number of neutrons produced per fission event, so it has a smaller critical mass. Pure 239 Pu also has a reasonably low rate of neutron emission due to spontaneous fission (10 fission/s·kg), making it feasible to assemble a mass that is highly supercritical before a detonation ...
The most stable are 244 Pu with a half-life of 80.8 million years; 242 Pu with a half-life of 373,300 years; and 239 Pu with a half-life of 24,110 years; and 240 Pu with a half-life of 6,560 years. This element also has eight meta states ; all have half-lives of less than one second.
In contrast, the generic civilian Pressurized water reactor, routinely does (typical for 2015 Generation II reactor) 45 GWd/tU of burnup, resulting in the purity of Pu-239 being 50.5%, alongside a Pu-240 content of 25.2%, [5] [6] The remaining portion includes much more of the heat generating Pu-238 and Pu-241 isotopes than are to be found in ...
The California Department of Motor Vehicles (DMV) is the state agency that registers motor vehicles and boats and issues driver licenses in the U.S. state of California. It regulates new car dealers (through the New Motor Vehicle Board), commercial cargo carriers, private driving schools, and private traffic schools.
Plutonium is a chemical element; it has symbol Pu and atomic number 94. It is a silvery-gray actinide metal that tarnishes when exposed to air, and forms a dull coating when oxidized. The element normally exhibits six allotropes and four oxidation states. It reacts with carbon, halogens, nitrogen, silicon, and hydrogen.
Plutonium compounds are compounds containing the element plutonium (Pu). At room temperature, pure plutonium is silvery in color but gains a tarnish when oxidized. [1] The element displays four common ionic oxidation states in aqueous solution and one rare one: [2] Pu(III), as Pu 3+ (blue lavender) Pu(IV), as Pu 4+ (yellow brown) Pu(V), as PuO +
Plutonium-239 and 240 emit ionizing radiation in the form of alpha particles. Inhalation is the primary pathway by which plutonium enters the body, though plutonium can also enter the body through a wound. [51] Once inhaled, plutonium can increases the risk of lung cancer, liver cancer, bone cancer, and leukemia. [22]
