At Hanford, strontium is separated from high-level wastes, then converted to the fluoride, and doubly encapsulated in small, high-integrity containers for subsequent long-term storage. The fluoride conversion, encapsulation and storage take place in the Waste Encapsulation and Storage Facilities (WESF). This encapsulated strontium fluoride represents an economical source of /sup 90/Sr if the WESF capsule can be licensed for heat source applications under anticipated use conditions. The objectives of this program are to obtain the data needed to license /sup 90/SrF/sub 2/ heat sources and specifically the WESF /sup 90/SrF/sub 2/ capsules. Research progress is reported on long-term compatibility of TZM with /sup 90/SrF/sub 2/, short-term compatibility of cast iron and Hafnalloy with /sup 90/SrF/sub 2/, and the oxidation resistance and seawater corrosion of Hastelloy C-4.
