That's a great question. When you look at a truly economic competitiveness environment, you have to look at both the construction costs and the long-term operating costs, that is, with a total cost-of-ownership perspective. It's not only imperative that the construction costs be competitive but also the operating costs. Again, for a two-unit type of power plant, you're looking at a couple of hundred people to operate it in total, and that would include maintenance, operating, security, all of those types of things.
One of the features of our design is that it only needs to be refuelled every four years. It was specifically designed that way to reduce the amount of continuous on-site presence and logistics requirements. That period is approximately twice as long as the normal refuelling interval for a large non-CANDU-type heavy water reactor.
