ABSTRACT:
A process for recovering Na from a spent NaS cell, includes the steps of forming an opening in a spent NaS cell, flowing down molten Na from an interior of the NaS cell through the opening in a heating oil vessel, passing the molten Na through a filter placed in the heating oil vessel to remove metallic powder, collecting the molten Na in a bottom portion of the heating oil vessel by utilizing a difference in specific gravity between the molten Na and an oil, and taking out the Na from an outer side of the filter.
