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

摘要

After dissolving irradiated nuclear fuel in a nitric acid medium, the vapor produced by this dissolution and consisting of water, nitrogen oxides and iodine is passed into a condenser, then into a column for the absorption of the nitrous vapor in which is formed recombined nitric acid containing iodine and nitrous ions, the iodine contained in the recombined acid being then separated-out. The method of the invention is useful in extracting, trapping and storing of radioactive iodine contained in irradiated nuclear fuels.
