- Accumulations of two solid phases occurred in the Savanah River Site (SRS) 2H-Evaporator system since late 1996. The aluminosilicate scale deposits caused the evaporator to become inoperable in October 1999. Accumulations of the diuranate phase have caused criticality concerns in the SRS 2H-Evaporator. In this study, thermodynamically derived activity diagrams, also known as stability diagrams, are developed from historic analytic data from the SRS 2H-Evaporator system feed tank (Tank 43H) and drop tank (Tank 38H) in order to understand the tank chemistry conditions that caused the scale formation in the 2H-Evaporator. The SRS 2F-Evaporator system, which is not precipitating aluminosilicate solids, is modeled for comparison.
