Let me respond by saying that I keep hearing people referring to an aging, creaky, leaky NRU production, but there is no real set time for some of those reactors. If you look at what's happening in power reactors, they're being refurbished and put in place. Some of them are running for 60 years, and people are arguing that they may run for 100 years.
The way to do it is to continue to improve safety. If there is any problem, you replace it. That's exactly what AECL will have to determine, the extent of.... It's not the aging; it's a corrosion. There's some real reason for this particular corrosion, and they have to determine the extent of this corrosion.
