METHOD OF EXTRACTION, TRAPPING AND STORAGE OF RADIOACTIVE IODINE CONTAINED IN IRRADIATED NUCLEAR FUELS

摘要

ABSTRACTAfter dissolving irradiated nuclear fuel in anitric acid medium, the vapor produced by this dissolutionand consisting of water, nitrogen oxides and iodine ispassed into a condenser, then into a column for the absorp-tion of the nitrous vapor in which is formed recombinednitric acid containing iodine and nitrous ions, the iodinecontained in the recombined acid being then separated-out.The method of the invention is useful in extracting, trappingand storing of radioactive iodine contained in irradiatednuclear fuels.
