Yes. Yes. Thanks, Bob. Let me give maybe sort of a broad perspective on that product line and this development. I think of -- for products like this, you can think about sort of 3 big phases: the research and development phase, of course, which we exited a long time ago; the industrialization phase, which we are going through right now; and then, of course, commercialization phase, that's what everyone's been most interested in. And so we're at the very tail end of industrializing that product line.
And by the way, it's overlapping with commercialization of that product. And so when you think about the industrialization phase, the systems that we've described to you, and you've seen them, you've put your eyes on them for the most part, but it's really exercising the target delivery system and then exercising our radiochemistry and radiopharmacy line. There's other things, too, waste management systems and other such, but those are the big 3.
And by the way, let me pause for a second and remind you that, as Robb said about the -- in his previous answer, we pivoted from a MURR radiation campaign and went directly to the target delivery system, which did cost us some schedule, but it avoids having to do a second filing to get that product approved by the FDA. So I think we're going to look in the rearview mirror and see that as a good decision.
So where we are is we have exercised our target delivery system. We've run targets through the reactor at Darlington in a high-neutron flux environment and produced high activity targets. We have exercised all 4 of those target elevators. We frankly had to work out some kinks in that system, which we have done so. It's working very well now. We have run those high activity targets through radiochem and radiopharm. And I would say that we are doing the final tweaking on both of those systems to get the product exactly right. I would say that we are very well pleased with the product quality. It meets all the drug pharmacopeia. And then we're working through sort of the final items of our checklist with the FDA.
In the meantime, we've been focusing on the commercialization phase. There is quite a bit of enthusiasm in the market for this product. So we've been doing some product testing by way of sending our generators to radiopharmacy networks and tagging our product with cold kits -- tagging cold kits with our product. We're working through in pretty serious ways now, supply agreements with the radiopharmacy networks. And we're working on logistics details now, the shipping costs and how we distribute the product, in particular, with which radiopharmacy. So I'd say I'm super well pleased with all that progress, and it's -- we're pushing through to the finish line.
