Abstract: A large amount of radioactive gas is generated during the reprocessing process in spent fuel reprocessing plants. The main forms of I-129 in the gaseous effluent of the reprocessing plants were investigated, and the current monitoring methods for radioactive iodine were summarized. By comparing their advantages and disadvantages, the online monitoring methods suitable for I-129 in the gaseous effluent of reprocessing plants were analyzed. And it is feasible to establish online monitoring technology for I-129 in the gaseous effluent in reprocessing plants. An ICP-MS based online monitoring technology for I-129 in the gaseous effluent in reprocessing plants could be established for experiemnt purpose, with the aim to monitoring the gaseous iodine molecules in the gaseous effluent in reprocessing plants, thereby achieving real-time monitoring of I-129 in the gaseous effluent in reprocessing plants.

Key words: spent fuel reprocessing, gaseous effluents, I-129, online monitoring, ICP-MS
