Reducing Radioisotope Concentrations in Reactor Effluent by High Coagulant Feed
This paper discusses a method to reduce the concentrations of radioisotopes and radioarsenic discharged to the Columbia River in Washington State by at least one order of magnitude (one‐tenth of the current levels), and at the same time, minimize the concentrations of the other radioisotopes. In‐pile evaluation of experimental water treatment processes designed to reduce the concentration of parent materials in the coolant was made by treating the water for one‐half of a reactor by the normal method and applying the proposed treatment to the other half. The use of a model treatment plant provided a transitional step between beaker test evaluation and plant application. More efficient parent isotope removal was obtained with the model than was observed in plant operation. For example, results from the model water treatment plant predicted removal efficiencies of greater than 93 per cent for arsenic and phosphorus compounds, compared with the 60‐75 per cent reductions actually observed. This discrepancy is due in part to mixing of the water between the two sides of the reactor.
