The file was generated using Python and Geochemist's Workbench (GWB). In Python, the parameters specified in the header are varied within their respective ranges, and GWB is then executed. Input parameters are: Solid/liquid ratio (SLR), pH, concentrations of UO2++, NpO2++, Am+++, Eh, Ca++, HCO3-, mineral composition in wt% (albite, orthoclase, quartz, goethite, phlogopite, illite, clinoclase). The conversion of the minerals to grams is based on the SLR and a water volume of 1 L. Output parameters are the Kd values of UO2++, NpO2++, and Am+++ as well as their logarithms to the base 10 (and the imbalance and imbalance error).
