You have the whole CANDU technology behind it. You have the medical isotopes business, which is providing 20 million treatments a year, a business that we created. You have all the research that goes on. On the neutron beams from Chalk River, we invented two major techniques in neutron scattering from that, which are now established worldwide. We have an international reputation and attract the best scientists and engineers to that facility to do both fundamental research and very applied research.
When Columbia blew up, we had pieces from their boosters coming in for analysis so we could understand what was going on in its welds. From rail cars to welds in space rockets, you name it, we've studied it.
