Pacific Northwest Laboratory monthly report to Advanced Nuclear Energy Systems, Space and Special Purposes Division for November 1975
Abstract
At Hanford, strontium will be separated from the high-level waste, then converted to the fluoride, and doubly encapsulated in small, high-integrity containers for subsequent long-term storage. The fluoride conversion, encapsulation and storage will 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. The information needed for licensing can be divided into three general areas: long-term SrF$sub 2$ compatibility data; chemical and physical property data on $sup 90$SrF$sub 2$; and capsule property data such as external corrosion resistance, crush strength, etc. The current program is designed to provide the required information.

Pacific Northwest Laboratory quarterly report to USERDA Advanced Nuclear Energy Systems, Space and Special Purposes Division, for July--September 1975
Progress during July to October 1975 in research on radioisotope heat sources is reported. The design of the long-term $sup 90$SrF$sub 2$ compatibility tests has been finalized. The effect of thermal aging on the impact strength of Hastelloy C-4 is being evaluated using Charpy test specimens. The solubility of SrF$sub 2$ in seawater and demineralized water was determined at 23$sup 0$C. The equilibrium concentration of Sr in demineralized water is greatly influenced by the presence of fluoride impurities in the SrF$sub 2$, whereas in seawater the presence of fluoride impurities has little effect on the Sr concentration. The effect ofmore »
