Okay.
What is clear—this has come up in the international discussions we're having—is that if somebody were to look today at creating a new production facility, including the cost of the waste and of going from high-enriched uranium to low-enriched uranium—which is what the United States wants to do, and involves burning more uranium, because it's not as enriched, and creates more waste—it does represent a very substantial cost that the market is unlikely to bear initially. That is one of the key obstacles to bringing forth new sources of production globally, including in the United States.
What the U.S. is doing right now is that they're advancing some sums to some parties to see whether there are some concepts that can be realized and can move forward in terms of production.
But you're absolutely right: the waste is a big issue in terms of cost and in terms of responsibility with regard to the production of isotopes.
