In Canada, like the United States, many of these reactors used to use highly enriched uranium, and in many cases weapons-grade highly enriched uranium. Both of our countries are working to convert to low enriched uranium. I believe—I imagine Mr. Barber can correct me if I'm wrong—that McMaster has in fact already converted to this and is not using highly enriched uranium. However, down the street from me, at MIT, for example, our colleagues there have 12.5 kilos of weapons-grade highly enriched uranium in the core of their research reactor.
Unfortunately, you can imagine that a little research reactor, with not very much revenue at a university, is not the kind of place where you're going to have the kind of armed protection you would imagine would be suitable for the kind of material you can use to make a nuclear bomb. That's one of the reasons I've been one of the strongest advocates pushing for eliminating the civil use of highly enriched uranium.
The United States is now on record saying we as a government want to eliminate completely all civil uses of highly enriched uranium. They're not needed anymore and they pose a security risk. I would love it if Canada, in its statement for December 2013 about minimizing the use of highly enriched uranium, would join us in that goal. I think it's the right goal of complete elimination from the civil sector.
