But it's nuclear safety, and you're very involved with what happens with the nuclear reactors across the country.
Is it true that one of the problems here was that it was designed to have a negative power coefficient and when it was operated it ran with a slightly positive power coefficient? As I understand it, it's true that some CANDU reactors actually do operate with a positive coefficient, but the issue is the predictability. Is that right? Could you comment on that?
