Okay. So there were technological problems with it. Were those problems being overcome, in your opinion?
We've heard from Dr. Waddington that there was a ton of issues with those things. They took a whole host of different approaches to try to solve that, including bringing in Idaho, including, I think, another national lab from the States, dozens of experts from around the world, all the AECL people, and they could not solve those problems even though they were trying some different things. Were those technological challenges being addressed and were they being dealt with, do you think, or were they at a stalemate?
