Progress in the strontium heat source and beneficial isotopes utilization programs is discussed. The couples required for the long-term tests compatibility were fabricated and the tests are under way. The 1000-hr tests were completed, and examination of the test couples has been started. Compatibility testing of two full-scale WESF /sup 90/SrF/sub 2/ capsules at 800/sup 0/C has started. Additional short-term compatibility testing of 25 potential containment materials are also under way. The 5000-hr aging tests of Hastelloy C-4 were completed and the specimens are being examined. Conceptual flowsheets were drawn up for recovery of various combinations of radioisotopes from stored high level wastes, and rough cost estimates were made. Additional calculations of /sup 137/CsCl capsule irradiation efficiency are reported. Conclusions of a study of the beneficial utilization of WESF /sup 90/SrF/sub 2/ capsules are presented.
