Evaluation of selective ion exchange to process liquid radwaste at Susquehanna

EPRI sponsored this engineering evaluation of the use of selective ion exchange to process liquid radwaste (LRW) at Susquehanna. This focused on the benefits and impacts of using selective ion exchange, however, it did not evaluate specific selective ion exchange technologies available for this application. Overall, it appears that the use selective ion exchange media for processing LRW at Susquehanna can be implemented with little or no changes to existing systems. The processing capacities of the radwaste and Make-up Systems are adequate to accommodate the discharge mode. It will be necessary to maintain the Make-up Water Treatment System in sound working order to achieve the water quality and system processing capacities required for the discharge mode. The environmental doses are likely to be somewhat higher than are now being achieved, but should still remain a small fraction of Appendix I guidelines. The use of selective ion exchange processing will essentially eliminate in-plant sources of organic. At reasonable low run length ratios, the economics will favor the use of selective ion exchange over conventional organic resin
