Solved: One way to utilize naturally occurring uranium
Chapter 5, Problem 5.148(choose chapter or problem)
One way to utilize naturally occurring uranium (0.72% 235U and 99.27% 238U) as a nuclear fuel is to enrich it (increase its 235U content) by allowing gaseous UF6 to effuse through a porous membrane (see the margin note, p. 215). From the relative rates of effusion of 235UF6 and 238UF6, find the number of steps needed to produce uranium that is 3.0 mole % 235U, the enriched fuel used in many nuclear reactors.
