The author seems to forget that separating U235 from U238, plutonium, and a slew of various highly radioactive and hazardous materials isn't exactly something you do in your shed with a couple of beakers. Especially if you want medical-grade concentrations of exotic isotopes... Saying that plutonium can be reused as fuel is also an assumption on the reactor technology used. Imagine even just transporting the spent fuel to another plant. You can't permanently cast it in concrete and glass if you want to recycle it. Many isotopes for nuclear medicine are also produced in accelerators, not by recycling.
