Abstract:
A method for separating zirconium, which is one of long-lived fission products (LLFPs), from a zirconium-containing radioactive solution (a high-level radioactive waste liquid), said method comprising adding molybdenum to the radioactive solution to form a precipitate comprising a product of a reaction between zirconium and molybdenum, and then separating the precipitate from the liquid.
