Quarterly report on the Strontium Heat Source Development program and the Beneficial Isotopes Utilization program, Division of Nuclear Research and Applications for January--March 1977. [WESF /sup 90/SrF/sub 2/ capsules]
Progress on the development of strontium heat sources is presented. Metallographic examination of the Haynes Alloy 25 specimens exhibited considerably more attack than was observed in the initial screening tests with Haynes Alloy 25 and /sup 90/SrF/sub 2/. Attack of the alloy was much greater at 800 and 1000/sup 0/C than at 600/sup 0/C, and the attack mechanisms appeared to vary with temperature. Decreasing the S/V ratio of the test couples produced a marked increase in attack at the higher temperatures. The addition of Zr and ZrF/sub 4/ to the WESF /sup 90/SrF/sub 2/, to simulate decay product buildup, resulted in a marked decrease in attack. The test couples from the 6000 hr tests with WESF /sup 90/SrF/sub 2/ were sectioned and the 36 metallographic specimens shipped to ORNL for examination. The first draft of a report detailing the design criteria and qualification requirements for the /sup 90/SrF/sub 2/ fueled heat source capsule was prepared and is now being reviewed. A draft report on the feasibility of heaters fueled with strontium fluoride capsules for use in cold regions is being reviewed. Similarly, comments are being obtained for the Study of Sludge Handling Alternatives Final Report and the General Application of Radioisotopes in Army Thermal Systems Final Report.
