[en] QUALITY (Quantitative Assessment Radionuclide Migration Experimental Facility) was constructed to investigate the radionuclide migration behavior under an aerobic condition. The construction commenced on Jan. 22, 1998 and completed on July 30, 1999. The operation was started on Aug. 18, 1999. This facility contains atmosphere controlled glove boxes to obtain basic data of radionuclide migration in engineered barrier materials and rocks on a laboratory scale. Various analytical equipments is available in this facility. This report presents the objectives, the outline and the data use. (author)
