Pacific Northwest Laboratory monthly report on the strontium heat source development program, Division of Nuclear Research and Applications for February 1977. [WESF /sup 90/SrF/sub 2/ capsules]
At Hanford, strontium is separated from the high-level waste, 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). The 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; (1) chemical and physical properties of /sup 90/SrF/sub 2/; (2) /sup 90/SrF/sub 2/ compatibility studies; and (3) capsule qualification and licensing.
