The answer is twofold.
First, the government has committed to ensuring that NRU can produce until October 2016. That's part of the funding going to AECL, to make sure that this will continue until 2016.
Then there are programs in our department, Natural Resources Canada, that have supported the development of alternative technologies, based not on reactors but on cyclotrons or linear accelerators, and bringing them to commercialization in a 2016 timeframe. Those would be Canadian technologies that would be able to compete in the market to try to sell medical isotopes after 2016.
Now, we have to understand that this is a global market, so the fact that NRU has decreased its market share over time has been compensated by other sources. Really, the isotopes are traded globally. We haven't seen the shortage in the magnitude we saw in 2009-10, which means the market has really adapted to the situation. When we look at the projections from third parties, from the OECD, the projections tell us that there will be enough capacity in the system and enough supply to meet demand.
