With regard to the operation and maintenance of the plants, as Patrick indicated, these plants have been producing power safely in Ontario now for over 40 years. They produce over 52% of our energy currently. Our members are quite comfortable with the operation.
I think it's important to know that, like any mechanical device, there are multiple safety systems. In areas where there's mechanical wear, are they going to wear out? Do you have to replace them? Absolutely. It's just like the brakes on your car, although when you're dealing with a nuclear station there's a significant magnitude involved.
Nonetheless, we have operated these things safely and efficiently for a good long time. We have the CNSC right on sight. They're the monitors. Do they find things from time to time? Absolutely. That's their job. That's what they're there to do. They point that out and those issues are corrected. We're quite comfortable with the CANDU model.
