Document Type and Number:
Japanese Patent JP2980844
Kind Code:
B2
Abstract:
After opening spent NaS cells, one or more NaS cells are loaded to and maintained in separator plates within a heating tank in such a way that the opening or openings thereof are oriented downwards. After no less than the time required to melt the Na and after Na has drained from the opening, the NaS cells from which Na has drained are removed from the separator plates within the heating tank and, in addition to this, a number of other opened NaS cells equal in number to those removed are loaded into and maintained in the empty spaces within the separator plates from which these NaS cells have been removed. In the recovery of Na, this method is efficient and time reducing and, furthermore, according to this method it is possible to make recovery facilities simpler and smaller.
