One of the major tasks involved in the recent Hanford strontium-90 recovery program was the purification of some 60,000 curies of strontium-90. One facet of this work was the defining of conditions necessary to contain and hold the strontium-90 for shipment from Hanford to Oak Ridge, where it would be pelletized and packaged. Of the methods considered for shipment, that accepted was the absorption of the strontium onto an inorganic exchanger contained in some suitable vessel. Decalso, a synthetic sodium aluminosilicate, showed this to be feasible. As a result, a special annular-shaped insent to hold Decalso, interchangeable with the filter unit of the HAPO I cerium cask already on hand, was designed. This insert was designed to hold 1.4 cubic feet of Decalso and was equipped with the necessary lines for slurrying the Decalso in and out and for the circulation of the strontium90 product solution through the Decalso. This insert was sealed into the cerium-cask body, and the combination is referred to as the HAPO-IA cask. To protect the cask against both mechanical shock and excessive heat in event of a fire, it was placed in an insulated buffer for shipment across country. A series of experiments are described that were performed to define the conditions necessary for loading the cask from the different types of strontium product solutions obtained from the recovery process in A-Cell.
