Multiphysics Modeling and Validation of Spent Fuel Isotopics Using Coupled Neutronics/Thermal-Hydraulics Simulations

Figure 9

Variation of isotopic concentrations of six major actinides with burnup for the 2F2D1/F6 rod. Note: g/gHmi means that the isotope mass (g) is normalized to the grams of heavy metal observed initially in the region at the beginning of cycle. (a) U-235. (b) U-236. (c) U-238. (d) Pu-239. (e) Pu-240. (f) Pu-241.
