No, there's more than a hope. If you look at the figures, there has actually been quite a movement in terms of more diversity of supply since that time.
If you look at 2010 and before that time, the NRU produced over 40% of the global supply of isotopes. Today it supplies between 15% and 20%, depending on when exactly you measure it. We've seen a decreased reliance on the NRU, but certainly it is a contributor.
The plan is to make sure that there are those other sources available when the NRU does cease to produce medical isotopes.
