Sure. It's not the cheapest proposal out there, I'll say that up front, and that's just to say it's establishing a new reactor. The approach we took involves a couple of things. One, we wanted to build on our existing strengths, and two, we wanted to put together a proposal that minimized technical risk, so our proposal is really modelled after the OPAL reactor in Australia. It recently came on line, so it's proven technology.
There's a sense of what it's capable of and there's a sense, at least in Australia, of what the costs might be, so our proposal is at a high level on costs. The costs are in the range of $500 million to $750 million in capital and then roughly 10% of that in terms of operating. As well, we've been quite clear with the proposal that the isotope business could account for approximately 15% of the operating revenues required to operate the facility. That's a high level view of the economics and some of what we based our proposal on.
