It's Elemental The Element Uranium

The Element Uranium. Uranium-238, uranium's most common isotope, can be converted into plutonium239, a fissionable material that can also be used as a fuel in nuclear reactors. To produce plutonium-239, atoms of uranium-238 are exposed to neutrons. Uranium-239

Uranium in ia

Milling consists of grinding the ore, then soaking the powdered rock through highly-alkaline fluids to separate out the uranium. The final product at the mine site is "yellowcake," with ore concentrated to about 80% uranium oxide (U 3 O 8).

Calculation of Decay Activity of One Gram of Natural Uranium

The final answer The total activity of one gram of natural uranium that has been sitting around for a few months or longer is the activity of uranium-238 and its decay products thorium-234, protactinium-234, and uranium-234 (49.2 kBq); plus the activity of the 0.72% of uranium-235 present and its decay product thorium-231 (1.1 kBq).

Secular Equilibrium in Radioactive Decay Chains

The uranium-234 starts producing thorium-230, but the latter has a half-life of 75,000 years, so it takes many thousands of years to accumulate to significant levels. Eventually, after about half a million years, the uranium reaches secular equilibrium,

Nuclear Fission Fragments

Fission Fragments. When uranium-235 undergoes fission, the average of the fragment mass is about 118, but very few fragments near that average are found. It is much more probable to break up into unequal fragments, and the most probable fragment masses are around mass 95 and 137. Most of these fission fragments are highly unstable ( radioactive ),

CHEMICAL, PHYSICAL, AND RADIOLOGICAL INFORMATION

For the uranium isotopes, this is a complex process involving the serial production of a chain of decay products, called progeny, until a final stable element is formed. The decay products of the uranium isotopes, which are also radioactive, are shown in Table 4-4.

What is the nuclear equation for uranium-238 after alpha

Explanation Uranium-238 produces thorium-234 by alpha decay. An α-particle is a helium nucleus. It contains 2 protons and 2 neutrons, for a mass number of 4. During α-decay, an atomic nucleus emits an alpha particle. It transforms (or decays) into an atom with an atomic number 2

Uranium-235 Chain Reaction

Uranium-235 Chain Reaction. A critical chain reaction can be achieved at low concentrations of U-235 if the neutrons from fission are moderated to lower their speed, since the probability for fission with slow neutrons is greater.

Uranium Element information, properties and uses

Uranium is certainly one of the most famous, or perhaps I should say infamous, elements. It is the heaviest naturally occurring element. It is actually more abundant in the earth's crust than silver. It is one of eight elements named in honour of celestial objects, but you might not think that uranium deserves to be named after the planet Uranus.
