I would not characterize it as a design flaw; I would characterize it as a design attribute. The decisions were made balancing many different factors—again, predating my arrival, so I'm only repeating what I'm told. But the decisions have been made to optimize the various factors in the design of the ACR-1000 in a way that achieves our objectives in performance, productivity, cost, and all the other factors that are important to our customers and are important to being competitive in the international marketplace.
Product development in any industry is iterative and involves examination of technical risk and the review of different alternatives. So as the concept and the definition of the next generation of CANDU reactor beyond the CANDU 6 took shape, inevitably changes were made. Design decisions were made, but not to correct flaws; in fact, to optimize the product and to make it as competitive as can be in the market.
