The Fuel Reprocessing Test Plant at JAERI was operated during the period of 1968-1969 to gain experiences of the fuel reprocessing.
Fuel elements reprocessed were irradiated in the JRR-3 reactor up to about 700MWD/ton and cooled for 87-300 days.
The purpose of this paper is to discribe the measured results of airborne radioiodine released in each stage of chemical processing and discuss collection efficiency of the charcoal impregnated filter paper for radioiodine in the presence of process off gas such as NO, NO2, NH3, HNO3 and solvent encountered during the fuel reprocessing.
