abstract

A number of sodium fast reactors around the world have been shut down permanently, most of which use sodium as coolant in liquid form. Owing to the extremely high chemical reactivity of sodium, radioactive sodium waste arising during decommissioning reactors requires unique treatment technologies. The paper introduces various technologies about treatment of radioactive sodium, as follows: drained bulk radioactive sodium treatment, polluted radioactive sodium treatment. By comparing the discussed technologies in the following aspect of advantages, disadvantages, limitations, industry experiences, hazards, and final waste products, the paper concludes with recommendations about the preferential treatment technology of radioactive sodium.
