Title: Aging Hanford Nuclear Waste and Simulants Using Carbon Dioxide to Evaluate Corrosion at Lower pH Limits

Abstract

Carbon dioxide gas was used to mimic the environmental chemistry that takes place as air contacts the surface layer of the waste solutions. Carbon dioxide acts as an acid in tank waste and has an affinity to the high pH solutions. Sodium hydroxide (a base) is added to tank waste according to waste handling specifications. This reagent is added in order to keep the tank metal protected from pitting corrosion. Problems that arise with performing sodium hydroxide additions are that volumes in some tanks are currently approaching capacity and every addition adds to the waste volume needing to be removed in order to close Hanford.
