Evolution and current state of radio-iodine control

The history, development, and problems existing in the US nuclear power reactor iodine clean-up technology are discussed. The areas of iodine transport in containment, adsorbent types, impregnation effects, mechanical and testing problems are reviewed, particularly in view of the TMI-II accident. The problems resulting from the fragmentation of responsibility and the very slow transfer of technology from research to application are pointed out
