Japan Atomic Energy Agency has been conducting STRAD (Systematic Treatment of RAdioactive liquid waste for Decommissioning) project for treatment of legacy liquid wastes accumulating in hot laboratories. In this project, fundamental studies to develop new technologies for the treatments are conducted utilizing stored liquids in Chemical Processing Facility (CPF) of Japan Atomic Energy Agency as reference. One of the challenging tasks is treatment of spent organic liquids involving spent solvent loading radioactive nuclides. In this study, several technologies for the spent solvent treatment were developed.
