Design, testing, and fabrication of heat sources for underwater application

Description: The sequence of events in the design, testing and fabrication of a radioisotopic heat source using available $sup 238$PuO$sub 2$ fuel that would be amenable to a Navy 0.5-W (electrical) Radioisotopic Thermoelectric Generator for undersea application is discussed. Various designs were considered as a function of heat leak in order to adopt the most desirable capsule for a volume- constrained application. Testing considerations are discussed for capsule compliance with IAEA/ENEA Safety Series 6 a… more

SNS source term evaluation program

Description: Plutonium-238 is currently used in the form of a pure refractory oxide as a power source on a number of space vehicles that have already been or will be launched during the next few years. Results are reported on aerosol experimental studies, that concern interactions between soils and $sup 238$PuO$sub 2$ aerosols which might be created in a space launch abort environment; marine animal studies, which concern support activities for the SNS underwater experiments; ultrafilterability studies, con… more

Pacific Northwest Laboratory monthly report to Advanced Nuclear Energy Systems, Space and Special Purposes Division for August 1975

Description: 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.… more

Savannah River Laboratory monthly report: {sup 238}Pu fuel form processes

Description: Progress during August 1975 in the development of {sup 238}PuO{sub 2} heat sources is reported. In studies to characterize {sup 238}PuO{sub 2}, the following were concluded: particle size was determined to be the most important characteristic affecting the variation in fabricability of {sup 238}PuO{sub 2}; problem feed consists of smaller particles (2 to 4 {mu}m) than older, acceptable feed (4 to 6 {mu}m). The particle size of new feed has varied from 3 to 10 {mu}m primarily as a result of vary… more
