Treatment of spent solvent in STRAD project

Radioactive liquid wastes generated in nuclear facilities such as nuclear power plants, reprocessing facilities, research reactors and laboratories often contain not only radiotoxic isotopes but also hazardous chemicals. 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. The facility has been operating mainly for development of reprocessing technologies of spent fast reactor fuel. More than 30 years operation with irradiated MOX fuel has generated many kinds of liquids, and those would be ideal targets of the studies. Several collaborative studies with universities, national organizations and private companies are launched to deal with each challenging task
