Abstract
AbstractA variety of low‐level radioactive waste streams are being generated from the decontamination and decommissioning of the former nuclear fuel reprocessing plant at West Valley, New York. It is presently planned to remove the radioactive contaminants from the solutions by ion exchange. Natural zeolites, such as clinoptilolite, erionite, chabazite, and phillipsite, were felt to provide desired flexibility and capacity under varying conditions. Batch and column testing were conducted on these materials using representative waste streams containing radioactive cesium, strontium, and cobalt. Sorption coefficients, dynamic decontamination factors, capacity, and sorption kinetics were determined. In addition, testing was conducted on prepared zeolites (i.e., Linde IE‐95 and A‐51) to provide comparative data.
