This behavior is different than that noted when the need for the specialized carbonate database was identified late in FY 99. ESP calculations for the sodium fluoride sulfate double salt will be revised to examine the use of the Gibbs free energy of formation for the pure species and for the double salt. ESP predictions for the solubility envelope in water indicate significant deviation from the literature experimental data with ESP predicting a lower solubility. Lindner, PI Feed stability and chemistry. Interfacing of the thermocouples and pressure transducers of the salt well pumping test loop with the data acquisition system was completed.
Calibration runs with water indicated equal pressure drops from the regularly spaced transducers.
Experiments using the modified SX-104 surrogate composition have begun and plug formation was observed. Observation of the plug indicated that the material was a gel consisting of sodium dodecahydrate. The data consisting of the pressure drops and temperatures are being analyzed and dilution experiments are in progress. Model development continued. A number of simulations were run where a plug was formed.
