I suppose that's what the Japanese said in terms of reasonable assumptions. When they were designing those reactors, they said it was outside of a reasonable assumption to assume a 9.0 quake.
I'm not suggesting a 9.0 earthquake is going to hit Ontario or Quebec or other places where there are nuclear reactors. I guess I wonder why you don't go up to a standard of a 9.0. Does it cost a lot more? Does it make the reactor unfeasible?
