First, as I say, it's very difficult to start talking about radioactive half-lives of components. You can easily mention the word “plutonium” and people immediately take that to a different point. You have to ask how much and in what form.
I think Dr. Thompson answered the question placed by one of the committee members earlier, which was, what is the absolute bounding...what's the worst thing that can happen, whether credible or not?
The most incredible thing is that all 16 steam generators somehow get smashed apart, and remember that these are 100-tonne pressure vessels, massive structures in themselves. We are assuming that they all get smashed to smithereens, and every piece of radioactive inventory that was inside every one of those steam generators gets released into the lake, right outside the water intake for the people of Sarnia. That's an incredible scenario, but let's assume it happens. Even in that scenario, it would only achieve 40% of their maximum allowable limit for safe drinking water. It doesn't even get close. That is such an incredible scenario, I might as well be planning a loss of gravity event. It does not compute. But that's what we did in an effort to reassure people.
