I'll take a shortcut on this. The most significant way to reduce costs would be in replication. The reason that nuclear plants have been expensive and have run over budget, which is perhaps even more of a concern because it leads to uncertainty in the minds of those who are investing in it, is that we keep building first-of-a-kind. We've had numerous examples around the world where new technologies are being developed that look very attractive, and will be very attractive, but that first-of-a-kind build runs into trouble. It's only later that the technology becomes well settled and people are building repeat plants. That has actually been the case in CANDU, where the CANDU 6 units built in the second generation around the world in the 1980s and 1990s benefited from being effectively a replication-type plant. I think that's one benefit, but that means there needs to be a sustained commitment to ordering that may be a worldwide agreement.
Glenn, do you want to comment?
