If I might, just before we go on, slide 15 in your deck is the schedule of what we call “retirement” or “replacement” of coal technology. So the utilities are facing this curve, in other words, and as this capacity comes off line, it will have to be replaced. So as John has said, the middle of that curve is about 2015, 2020, and as a consequence, it will have to move along to replace the capacity that was there before.
You asked a question about next generation nuclear. If you look at the current CANDU system, it's essentially a generation two or a generation two-plus of technology. The technologies referred to as “next generation” are those that will come on stream in 2025 to 2030. So these are technologies of an advanced nature. They often involve combinations of features that we don't have at this time.
Canada is participating in an international collaboration on these technologies, of which six have been chosen. We're participating in two of the six. We're leading on supercritical water reactors and we're working with the community on very high temperature reactors.
The program is built on a national basis. Certainly, Atomic Energy of Canada Limited is the leading performer. But we've also reached out to a number of universities and research institutes across Canada and government as well to try to build this knowledge toward the nuclear technology that will be put into practice at that time.
