The authors characterized surface and variable depth samples from the feed (Tank 32H) and drop (Tank 30H) tanks for the new Replacement High Level Waste Evaporator (3H) prior to startup. The results indicate very low silicon concentrations (less than 30 mg/L). Modeling of the aluminosilicate formation suggested little solid formation for the planned operation of the 3H Evaporator (approximately 1 g/L of supernate processed). The amount of solids predicted to form in the 3H Evaporator agreed with prediction for the operation of the 2H prior to the introduction of DWPF recycle waters.
