I think you'd have to go back and look at the experiments that happened, but in terms of the licences that we gave, which were these very specific licences to look at bringing it up to power.... I don't have the schedule in front of me; they were the licences at the very end. That's why there was this optimism that the problems could be solved. It wasn't until it really hit the fan that we knew it wouldn't work.
I'd like to emphasize that this positive coefficient of reactivity, and the fact that it doesn't correspond with the projected performance of the reactor, is extremely serious. And it was treated seriously by everyone, including AECL.
