What is a uranium Cascade?
A cascade consists of separation units, in this case centrifuges, arranged in parallel that make up a singlestage. The width of the cascade is the number of elements in a given stage. These elements receive identical feed and generate the same product and waste.
How many centrifuges are in a cascade?
The cascades have 15 stages each and are both composed of 164 IR-1 centrifuges.
How would you separate uranium-238 from uranium-235?
Thermal diffusion uses the transfer of heat across a thin liquid or gas to accomplish isotope separation. The process exploits the fact that the lighter 235U gas molecules will diffuse toward a hot surface, and the heavier 238U gas molecules will diffuse toward a cold surface.
What does a uranium centrifuge do?
The Zippe-type centrifuge is a gas centrifuge designed to enrich the rare fissile isotope uranium-235 (235U) from the mixture of isotopes found in naturally occurring uranium compounds. The isotopic separation is based on the slight difference in mass of the isotopes.
How do uranium centrifuges work?
To enrich uranium, yellowcake is first turned into a gas called uranium hexafluoride. This is pumped into centrifuges that spin so fast the ever-so-slightly heavier gas containing uranium-238 is forced to the outside, while the lighter gas containing uranium-235 stays in the middle.
Why is it difficult to separate U-235 and U-238?
“Enrichment” meant increasing the proportion of U-235, relative to U-238, in a uranium sample. This required separating the two isotopes and discarding U-238. Uranium-235 occurred in a ratio of 1:139 in natural uranium ore. Since they were chemically identical, they could not be separated by chemical means.
What is the difference between uranium-235 and uranium-238?
Uranium is a chemical element well-known for its radioactive decay. U-235 and U-238 are two radioactive isotopes of Uranium. The main difference between U-235 and U-238 is that the number of neutrons present in the U-235 nucleus is 143 whereas the number of protons present in the U-238 nucleus is 146.
What is the fastest centrifuge?
