Absolutely. The chemical and physical compositions of CANDU spent fuel are quite different from light-water reactor spent fuel. There are technologies—I think some colleagues mentioned fast reactor technology—that could use CANDU spent fuel as a waste product, to feed into it as a power reactor. What we are doing with the AFCR is adapting this reactor design to use light-water reactor spent fuel. Light-water reactors constitute 90% of the global fleet of approximately 440 reactors, and so what we're doing is utilizing the spent fuel from there.
You could move to what's known as a three-stage cycle—I don't want to get too technical—to use that. There is still a considerable amount of energy in CANDU spent fuel that could be used in other reactor types, such as the molten salt reactors and the fast reactors that we talked about, but that wouldn't be in a CANDU reuse application, per se.
