Essentially, we looked at the characteristics of the steam generators in terms of the content of radioactivity and the characteristics of the generator in terms of the radionuclides, which are not soluble, so it's a coating inside the tubes that is not soluble in water. There are plates that are welded shut, so there is no foreseeable manner in which the plates would fall off. Essentially we looked at those characteristics, and in our evaluation we looked at scenarios where the spikes....
Despite those characteristics, we made the assumption that radioactive material would find itself in water, and we looked at what the consequences to drinking water would be and hence to people who are drinking water. All those scenarios looked at steam generators falling into the Great Lakes or looked at the St. Lawrence or Owen Sound. We looked at the dispersion of material, contamination of drinking water plants, and what the consequences would be.
Even considering what is not possible because of the characteristics, no one would be exposed to levels of radioactivity that would approach the limit set for drinking water standards. No one would be at risk in terms of health.
