【 摘 要 】

Accumulations of two solid phases have formed scale deposits in the Savannah River Site 2H Evaporator system since late 1996. The aluminosilicate scale deposits caused the evaporator pot to become inoperable in October 1999. Accumulations of the diuranate phase have caused criticality concerns in the SRS 2H Evaporator. In order to ensure that similar deposits are not forming in the SRS 3H Evaporator, thermodynamically derived activity diagrams specific to the feeds processed from the 3H Evaporator feed tank (Tank 32) were evaluated.
