Why Uranium and Plutonium? Nuclear Fission Science ,
Why Uranium and Plutonium? Scientists knew that the most common isotope, uranium 238, was not suitable for a nuclear weapon There is a fairly high probability that an incident neutron would be captured to form uranium 239 instead of causing a fission However, uranium 235 has a ,...

Natural uranium deposits exist all over the world, but uranium in this form is not suitable for nuclear weapons, and cannot be used in most nuclear reactors for either electricity or plutonium production Natural uranium is composed of various isotopes, or different types of uranium It contains approximately 993 of the isotope uranium-238 ....
Plutonium Manufacture and Fabrication All plutonium originates in nuclear reactors and is produced by the capture of extra neutrons by uranium-238 to form U ,...
Are the peaceful and military uses of uranium incompatible? Nuclear reactors fuelled with uranium automatically produce plutonium as a byproduct If that plutonium is chemically separated from the rest of the radioactive garbage in the spent reactor fuel, it can be used as a nuclear explosive...
Fissile Materials Basics Nuclear reactors and nuclear weapons derive power through the fission splitting of nuclei of uranium or plutonium atoms, a process that releases large amounts of energy These fissile materials are used for a variety of civil and military purposes, as shown in the table below Uranium...
Uranium and plutonium resource basics For all practical purposes, uranium-235 is the only naturally-occurring fissile material one that can sustain a chain reaction and can fuel nuclear reactors However, uranium-235 makes up only about 07 percent of natural uranium ore...
Japan, Bowing to Pressure, Defers Plutonium Projects
Feb 22, 1994 0183 32 By the 1990 s, the Government said, uranium would be scarce and expensive, making the high cost of recovering plutonium from spent nuclear fuel a bargain Uranium ,...
Plutonium and Reprocessing of Spent Nuclear Fuel Frank N von Hippel Historically, chemical separation or reprocessing technologies have been used to separate the plutonium and uranium in irradiated nuclear fuel from fission products and from other isotopes that have built up as a result of neutron absorption Reprocessing is as old as...
Jun 27, 2006 0183 32 Plutonium was discovered in the US in 1941 when scientists exposed uranium to neutron radiation in a laboratory There is nothing natural about it, and has only been in the environment since the first atomic bomb was detonated in the US in 1945 in the Japanese city of Nagasaki and killed 50,000 people in August 1945 The bomb contained only 61 kilograms of plutonium...
