ABSTRACT:
process is disclosed for disposing of a spent NaS cell, which process comprises the steps of: cutting an opening in the NaS cell for flowing out sodium from the cell and allowing an inner tube to be pulled out from the NaS cell; placing oil on sodium inside the inner tube of the spent NaS cell in a given thickness, while the cut opening is directed upwardly; setting the spent NaS cell in a workpiece-setting vessel outside a heating oil vessel, while the cut opening is directed downwardly, thereby flowing out the oil on the sodium inside the inner tube, said workpiece-setting vessel being provided at a bottom with a hole for allowing an inner tube to be pulled out from the the spent NaS cell, immersing the spent NaS cell set in the workpiece-setting vessel into oil in the heating oil vessel in the state that the cut opening is directed downwardly; sodium is melted in the oil of the heating oil vessel and flown out therein through the cut opening; and then the inner tube is pulled out from the NaS cell.
