I'll say a couple of things.
First of all, as we are all now well aware, the half-life of isotopes is such that you're really dealing with, in some cases, a 72-hour timeline, so it's not the usual situation in which you can stockpile supplies. I wish it were not that way, but that is the way it is with radioisotopes. That's the first issue.
The second issue was that we had almost a perfect storm of circumstances around this shutdown, in that at the same time as the unscheduled shutdown, because of the regulatory issues with Chalk River and the NRU, two out of the four were also in scheduled shutdown at precisely the same moment. If you believe in Murphy's law, then certainly we faced a variation of that.
I think the protocol we have in place right now, Ms. Bell, will be helpful in this regard.
