A Critical Review of the Recent Improvements in Minimizing Nuclear Waste by Innovative Gas-Cooled Reactors

Figure 10

Spent fuel radiotoxicity versus time for GCFR, “final” step (“waste” = FP): LOMBT = 159 years. (The fission products considered here are the following: Rb⁸⁷, Sr⁹⁰, Zr⁹³, Nb⁹⁴, Tc⁹⁹, Pd¹⁰⁷, Sn¹²⁶, I¹²⁹, Cs¹³⁵, Cs¹³⁷, Sm¹⁴⁷, Sm¹⁵¹, and Eu¹⁵⁴.) (If we would consider as waste FP and MA, the LOMBT would become equal to 20491 years.)
