The higher enrichment needed the more enrichment and stripper stages needed. However the speed of enrichment depends more on how fast you can pump the uranium hexafloride through the individual stages without exceeding their limits. These limits will vary depending on enrichment technology used.
No, the atomic bomb and depleted uranium are not the same thing. Nuclear weapons are made with enriched uranium or with plutonium as the fissionable material. Depleted uranium is uranium that is "left over" after natural uranium is put through a process called enrichment to inprove the concentration of the isotope U-235 over that in natural uranium. The enriched uranium with its higher percentage of U-235 is fissionable, and it can be used in nuclear reactors and in nuclear weapons. Depleted uranium is used to make armor-piercing projectiles, and can be put through the neutron flux in an operating reactor to be transformed (transmuted) into plutonium.

The Olympic motto "Citius, Altius, Fortius" is Latin for "Faster, Higher, Braver," but is universally accepted to mean "Swifter, Higher, Stronger."
You say: Plus vite, plus élevé, plus fort.
Hz on a RAM is the speed of which the hardware can read. the higher the Hz the faster RAM.
Enrichment of uranium in the isotope 235U by: - centrifugal separation - gaseous diffusion separation - many other methods - not so important today
The references I have state Oralloy is 93.5% U235. Oralloy (Oak Ridge Alloy) was used in US Uranium atomic bombs as the fissile material. However they also say that any enrichment 20% U235 or higher is fissile and could be used to make a bomb, it would require a higher critical mass to work though. One source I have states that early Soviet Uranium atomic bombs used ~97% U235, but the US felt this level of enrichment to be unnecessary and excessively expensive.
Academic enrichment refers to programs, activities, or opportunities that go beyond the standard curriculum to enhance students' learning experiences. These may include advanced courses, workshops, research projects, study abroad programs, or extracurricular activities geared towards developing critical thinking, creativity, and specialized skills. The goal of academic enrichment is to provide students with a more well-rounded education and prepare them for success in higher education and future careers.
235U with a 5% enrichment of 238U is generally used to fuel a controlled nuclear chain reaction. In a navy nuclear application, such as a submarine, a higher enrichment of 238U is used, around 20%.

Enriched uranium is uranium that has had its U-235 isotope content elevated above what it would be when we refine natural uranium after recovering the metal from ore.We know that U-235 is the desired fissionable isotope of uranium, but it is the isotope U-238 that is present in over 99% of all the naturally occurring uranium we mine and recover. We have to put the uranium through a process to separate the U-235 from the U-238. As these two isotopes are chemically identical, it takes a mechanical process to separate them. After running the uranium through a process designed to take advantage of the difference in the mass of the two atoms, the industry will recover uranium with a very high percentage of the U-235 isotope, and this is called enriched uranium.If uranium is enriched to a point where there is up to about 20% U-235, it is low-enriched uranium. Above that 20% mark we see highly enriched uranium. Above about 85%, we call the product weapons-grade uranium. A link can be found below for more information.
All the isotopes of uranium are radioactive !
Enriched uranium is still usually mainly 238U, but it has a higher percentage of 235U than the natural abundance. Depleted uranium is exactly the opposite: it's got a LOWER than normal amount of 235U.

In a fast reactor there is no moderator, which in most (almost all) fission reactors used for power production is provided to slow down the neutrons produced in the fission reaction. This is because the capture cross-section of U-235 and PU-239 is much larger for slow neutrons, enabling the use of low enrichment fuel, or even natural uranium fuel with a graphite or heavy water moderator. In a fast reactor the fission chain reaction is sustained by fast neutrons, ie as produced by the nuclear fissions. This requires a higher enrichment of the fuel. Typically this could be 20 percent Pu-239, and the remainder Uranium. This type of reactor can actually breed more plutonium from the U-238 in the fuel and in a blanket around the reactor, since neutrons are absorbed into the U-238 turning it into Plutonium. However liquid metal (sodium or sodium/potassium) is nasty stuff to handle and the costs of the engineering involved have not been attractive enough for commercial use so far.
- the energy released from enriched uranium is higher compared to natural uranium- the amount of uranium needed for a reactor is lower- research reactors work only with enriched uranium- atomic bombs have highly enriched uranium or plutonium
