Description

Development of accident consequence analysis method bas been under carried out at Japan Atomic Energy Agency as a part of research activities for development of probabilistic safety assessment method of nuclear fuel facilities. A computer tool has been developed to simulate boiling event of reprocessed liquid waste which is postulated to be occurred caused by the loss of cooling function at a fuel reprocessing plant. Thermodynamic properties of boiling and condensed nitric acid aqueous solution containing radioactive waste are necessary to assess quantitatively the amount of radioactive materials transferring to gas phase. The developed tool simulates boiling and condensation process of liquid waste based on the ebullioscopy. A simulation study of experimental result has been carried out and it was demonstrated that behavior of temperature and concentration of nitric acid of liquid waste are simulated well. (author)
