Thermodynamic description of U(IV) solubility and hydrolysis in chloride systems: Pitzer activity model for the system U$^{4+}$–Na$^+$–Mg$^{2+}$–Ca$^{2+}$–H$^+$–Cl$^-$–OH$^-$–H$_2$O(l) [PDF]
This study presents updated chemical, thermodynamic, and activity models for the system U$^{4+}$–Na$^+$–Mg$^{2+}$–Ca$^{2+}$–H$^+$–Cl$^-$–OH$^-$–H$_2$O(l)derived using the Pitzer formalism and a strict ion interaction approach.

CSH-Phasenbildung und Löslichkeitsverhalten vor dem Hintergrund der Anwendung von Zement in Endlagerkonzepten für radioaktive Abfälle [PDF]
Die Bildung und Beständigkeit von CSH-Phasen wurde in Abhängigkeit von Zeit, Ca/Si-Verhältnis, Temperatur, SiO2-Reaktivität, w/s-Verhältnis und NaCl-Sättigung der Lösung untersucht.

Experimentelle und model-theoretische Untersuchungen des chemisch-hydraulischen Verhaltens von Sorel- und Salzbeton als Dichtelemente im Steinsalz [PDF]
For the safe disposal of radioactive waste in Germany the enclosure of the waste in deep geological formations is foreseen. During mining activities, the host rock is penetrated by shafts and drifts, which must be plugged by sealing elements of adequate ...

Sorption Modelling of Np(IV), Np(V), and Pd(II) on Illite and Montmorillonite Under High Ionic Strength Conditions [PDF]
A database is being developed by the NWMO that will be capable of predicting sorption for key elements of interest onto crystalline and sedimentary rocks in the highly saline groundwaters and porewaters at DGR depths in Ontario, Canada. Pd(II), Np(IV),

Implementation of Carbonates and CO2 into the T-dependent Pitzer Model of Oceanic Systems. I. System NaOH – Mg(OH)2 – Ca(OH)2 – CO2 – H2O [PDF]
The THEREDA model has been extended by phases and species formed within the title system. A temperature range of 0 °C to 100 °C is considered. Most of the solubility products, Pitzer parameters and association constants were adapted from the model of ...
