In the Introduction, we talked about separating the useful 0.7% of Uranium from the 99.3% of the useless Uranium. The two Uranium's are different due to their masses.

The useful Uranium is about 1.3% lighter than the useless Uranium. It is this difference in the physical property that is used to separate the two Uranium's.

The separation process is extremely complicated and expensive as the mass difference is so tiny. In fact, this is the reason most countries don't have nuclear power/weapons!
