If I might, I'll comment on the question of regulatory inflexibility and net benefit, which was the question raised, and I'll help answer what you've just raised as well.
Let me make the point that the question of regulatory inflexibility is a bit of a historical thing. It happened then. Things have certainly changed in recent times with the way CNSC operates, as best as I'm able to tell.
What we got cornered into in the 2002 to 2006-08 timeframe was trying to prove a philosophical negative: Tell me something doesn't exist; I don't like positive reactivity, so try to prove to me that it doesn't exist. That's where the whole simulation question got stuck.
