“We do like to work with the customer to define a source of enriched material. Once we define that source of material it becomes easy to work with.  Now to say, if we had to work with something that was at a very low level, that means is it’s detectable.  Because it’s separatable, we can scale that separation up, and at a minimum, isolate the small peak.  So, given the fact that you can detect it at 0.01% means it is possible to isolate it.”
