There are a number of things that happen. In the event of an unexpected shutdown, they would go into the isotope supplies that we have and would manage that supply to ensure that the most urgent needs are met. Then we would engage with our international partners around the world, looking for alternate supply and doing everything we can.
We don't expect that to happen. As I said earlier, the NRU is operating more safely today than it ever has before in its 50-year history. It has more safety systems on it today than ever before. The CNSC is part of the checks and balances and inspections that happen, to ensure that it can be operated safely and can continue to operate.
Again, we don't anticipate that there will be any issues there. It's not impossible, but it's not something of which I believe there's a very high risk of its happening.
