Again, I can't give you a date. As I said before, this is determined by the aging management program and the inspections that we do going forward.
We are committed to operating the NRU through the next licence interval, 2011 to 2016. We believe it can be operated cost-effectively beyond that point. There is no defined end date when the NRU will be taken out of service. That will be determined as we continue to gather data on the aging over the years ahead.
