The objective of the program discussed in this report has been to develop an on-line aqueous organic digestion process that decomposes the organic compounds in water to ionic species, which can then be removed by the plant's demineralizers. At the Susquehanna Steam Electric Plant (SSES) of Pennsylvania Power and Light Company (PP L), the sonolysis process was tested by application to standard water streams to which ethylene glycol and urea were added. There were a substantial number of ionic species generated from both compounds as determined by ion chromatography. The sonolysis process and another organic destruction method, the General Electric ozone/UV process, were compared for their ability to remove the total organic carbon (TOC) and total inorganic carbon (TIC) from streams from the collection tanks of the plant's radwaste system. The sonolysis process efficiency, evaluated after the effluent from sonolysis was passed through a demineralizer, was estimated to be 55 + 17% for TOC removal as compared to a 93% removal by ozone/UV. Sonolysis led to the removal of 93% of the TIC as compared to 100% by the UV/ozone process.
