“…In this section, a set of general pathway dose factors (PDFs) was derived for each radionuclide at its unit activity concentration based upon the processing and transportation of a reference SG of the Optimized Power Reactor (OPR 1000) with a weight of 540 tons and reported physical dimensions of 21 m in height and 5.7 m in outer diameter [25,26]. In total, 26 radionuclides are referenced from publicly available inventory data for SGs from a PWR (Kori Unit 1) and a PHWR (Bruce A Unit 1) and considered in the general assessment [14,27]: eight actinides ( 237 Np, 238 Pu, 239 Pu, 240 Pu, 241 Am, 242 Pu, 243 Am, and 244 Cm), six fission products ( 90 Sr, 99 Tc, 106 Ru, 129 I, 137 Cs, and 144 Ce), 10 activated corrosion products ( 54 Mn, 55 Fe, 57 Co, 59 Ni, 60 Co, 63 Ni, 65 Zn, 94 Nb, 125 Sb, and 154 Eu), and two others ( 3 H and 14 C).…”
