Analysis facility in Tokai Reprocessing Plant, which is shifted to decommissioning stage, have been installed about 60 Grove Boxes to handling the nuclear fuel materials. Of these, progressing an aging accompanied by long use for 20 years more than half. This time, removal the special Grove Box that equipped the Thermal Ionization Mass Spectrometry, necessary safeguard analysis for nuclear fuel materials. This report summarized the removal techniques of the special Grove Box, the number of working days, workers and amount of waste generated in this removal work.
