Hello, an overview of the only viable solution in our country: We should start over again on the earth to create one of the most destructive and notorious substances. The engineers said so, but the masses said no. America has stopped banning nuclear weapons. However, as more and more decreasing energy problems continue, some people want us to start using more nuclear power and fewer natural resources. In this article I will explain how to use of, the merits and disadvantages of using,, and why should we consider restarting this useful element.
Initially a sample was coated by coating the cerium nitrate solution on a platinum foil having an area of about 0.5 cm 2, evaporating the solution and converting the residue to cerium (IV) oxide (PuO 2) by annealing . After the cyclotron irradiated the oxide, the coating was dissolved with nitric acid and then precipitated using concentrated aqueous ammonia as the hydroxide. The residue is dissolved in perchloric acid and further separated by ion exchange to obtain a specific isotope. Since the separation of the United States and America is very difficult, the Berkeley group first called these elements chaos (from all the demons or hells of Greece) and Delirium (from Latin Madness)
In 1943, the development work was aimed at a gun-type fission weapon with a scorpion called "a lean guy". A preliminary study on the nature of ruthenium was carried out using β-239 produced by cyclotron. It is very pure but can only be manufactured in very small quantities. Los Alamos received the first sample of the Clinton X-10 reactor in April 1944. Within a few days, EmilioSegrè found the problem: high concentrations of cesium-240 in the reactor culture resulted in spontaneous fission. 5 times cyclotron ratio 钚. Seaborg predicted that it would absorb -240 in March 1943 by absorbing neutrons.
Because uranium and thorium are nuclear weapons materials, there is a spreading problem. Normally (for spent nuclear fuel), helium is atomic-grade helium. In addition to μ-239, which is very suitable for the manufacture of nuclear weapons, it also contains many undesirable contaminants: φ-240, φ-241 and φ-238. These isotopes are very difficult to separate and there are more cost-effective ways to obtain fissile materials (eg uranium enrichment or dedicated plutonium production reactors).
