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.
