Theoretically I would say yes for somebody who uses the same fuel. The main driver fuel in the HANARO reactor is similar to that in MAPLE. It would not be a small matter: you'd have to do a complete new physics analysis, because you replace some of the normal fuel with this very specialized target fuel from which you harvest radioisotopes. That's a very specialized fuel and gives you very strange flux shapes; that is, if you look at the neutron density across the core, in a power reactor you'd generally like a nice smooth shape and for it to be very nice and predictable. When you put a small amount of highly enriched uranium in a small spot to give you your source of isotopes, you get very big peaks in flux shapes, so you'd have to go through that physics analysis and so on.
But theoretically, I would imagine it is possible.
