Enrichment of uranium-235 is done.
A cascade is a stage in the process of uranium enrichment; a plant has thousands successive cascades.
Enrichment of uranium in the isotope 235U by: - centrifugal separation - gaseous diffusion separation - many other methods - not so important today
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.
Enrichment
Uranium-235 is not added to natural uranium, it is extracted from natural uranium by a process called enrichment.

See the link below for an MSDS on uranium. Note that each compound has it's own MSDS. Also important is the enrichment of uranium, the quantity, the physical form of a compound, etc.
Enrichment of uranium in the isotope uranium 235 is made by gaseous diffusion or by centrifugation.
The uranium enrichment facilty was at Oak Ridge.
1. The material for enrichment is the uranium hexafluoride (UF6) not uranium dioxide pellets. 2. For a nuclear fission and and a nuclear chain reaction we need thermal neutrons.
