Yes. With respect to spent nuclear fuel, the system is as follows: We refuel our CANDU plants continuously on load. We move our fuel. We store it on-site, underwater. We have a fuel base with a capacity sufficient to take about 25 years of normal operation.
I think many of you would be somewhat surprised to see the volume of waste that's been generated in such a long operating period. It's not as large as perhaps people might think. Over the last three or four years we have been moving fuel progressively from this underwater storage into dry fuel storage casks, which are effectively lowered into the water. So all this fuel is handled underwater. It's put inside a concrete cask. The water is then evacuated, and they are stored and sealed. They are all transported within the Bruce site into dry fuel storage concrete casks, which are capable of storing the fuel for up to 100 years.
This is an integral part of the adaptive phased management program. For example, fuel can come from the reactor. It can stay in the fuel bay for 25 to 30 years. It can then be moved into concrete casks, which again can be stored on the site for 100 years. The intention of the adaptive phased management is that after this, they will then be moved to a central location, which has yet to be determined.
All that is managed by federal regulation. Everything we do on the site is part of federally regulated activity. We are the licensee for the site, so whether we own the assets or not, as a licensee we are bound by the federal regulations for all those activities.
