Management of Iodine in Fuel Reprocessing Plants

Systems for removal of iodine from gaseous effluents at fuel reprocessing plants have generally been classed into primary, secondary, and final cleanup systems. Primary iodine removal systems are de-

Numerous fuel reprocessing plants have been operated (or planned) that included iodine removal systems on the gaseous effluent streams (CEC, 1982a). Table 6.1 lists several reprocessing plants along with type of iodine removal system used at each and the overall stack decontamination factor. Overall stack DFs can vary considerably compared to the theoretical efficiency of the individual systems because of routing in the plant of streams that may contain iodine.
