It would be a bit difficult for me, because I'm not really an actor in this field, but I would imagine that some Canadian universities may be working in the area of nuclear energies and the nuclear fission reaction. AECL could also be pretty much involved.
We also have to realize that nuclear energy is still a global energy, so the American trades are also contributing quite significantly to move the field forward. I could give you the example of France, which is very active in this file, because a lot of their energy is basically coming from nuclear fission and nuclear reactors.
The United States could also be very much involved in this file because, again, they have a lot of capacity in nuclear energy and nuclear physics through the DOE National Laboratories and Technology Centers.
That would be the extent of my answer at this point in time. I apologize. I could try to get additional information, should you wish. I'd be glad to collect that information for you.
