Radioisotope production in fusion reactors is being investigated as part of the Fusion Applications and Market Evaluation (FAME) study.[1] 60Co is the most promising such product identified to date, since the 60Co demand for medical and food sterilization is strong and the potential output from a fusion reactor is high. Some of the other radioisotopes considered are 99Tc, 131I, several Eu isotopes, and 210Po. Among the stable isotopes of interest are 197Au, 103Rh, and Os. In all cases, heat or electricity can be coproduced from the fusion reactor, with overall attractive economics.
