The blossoming of cooperation between the U.S. and Canada
The United States and Canadian nuclear industries used to be an example of how two independent teams of engineers facing an identical problem—making electricity from uranium—could come up with completely different answers. In the 1950s, Canada began designing a reactor with tubes, heavy water, and natural uranium, while in the U.S. it was big pots of light water and enriched uranium.
But 80 years later, there is a remarkable convergence. The North American push for a new generation of nuclear reactors, mostly small modular reactors (SMRs), is becoming binational, with U.S. and Canadian companies seeking markets and regulatory certification on both sides of the border and in many cases sourcing key components in the other country.

We show that it is possible to denature the plutonium produced in pebble bed modular reactors by doping the nuclear fuel with either 3050 ppm of 237Np or ~2100 ppm of isotopic composition of Am. A correct choice of these isotope concentrations yields denatured plutonium with isotopic ratio 238Pu/Pu 6%, for the entire fuel burnup cycle. The penalty for introducing these isotopes into the nuclear fuel is a subsequent shortening of the fuel burnup cycle, with respect to a nondoped reference fuel cycle, by ~40 and 20 full-power days, respectively, which correspond to 4.1 and 2.0 GW(d)/ton reduction in fuel discharge burnup.
