Framework model for hydrogen redistribution in Zircaloy sheathing

Multidimensional simulations of hydrides during fuel rod lifecycle

“…Notably, only Sawatzky's model reasonably fits the data from the experiment, yet this model does not account for hysteresis between T SS d and T SS p nor does it use a finite precipitation rate. (Not shown in Figure 2 is that the model of [28] also fits the data well since it is very similar to Sawatzky's model and also neglects the hysteresis.) To investigate this difference, we first note that the solvus given by Sawatzky is much higher than the other results in Table 1.…”
