/sup 238/Pu fuel-form processes. Quarterly report, October-December 1981

Description: Progress in the Savannah River /sup 238/Pu Fuel Form Program is summarized. Work during this period concentrated on the extensive cracking of the /sup 238/PuO/sub 2/ fuel form prior to encapsulation in the iridium containment shell for heat sources. This cracking results in increased recycle cost and decreased production efficiency. To better understand this cracking, Savannah River Laboratory (SRL) has made an extensive review of the development of /sup 238/PuO/sub 2/ fuel forms from small-sca… more

Welding iridium heat-source capsules for space missions

Description: A remote computer-controlled welding station was developed to encapsulate radioactive PuO/sub 2/ in iridium. Weld quench cracking caused an interruption in production of capsules for upcoming space missions. Hot crack sensitivity of the DOP-26 iridium alloy was associated with low melting constituents in the grain boundaries. The extent of cracking was reduced but could not be eliminated by changes to the welding operation. An ultrasonic test was developed to detect underbead cracks exceeding a… more

SNAP-21 program, Phase II. Deep sea radioisotope-fueled thermoelectric generator power supply system. Final design description, 10-watt system

Description: The SNAP-21 10-W system provides electrical power for use under the surface of the sea. It functions by converting the heat from a decaying radioisotope fuel into useful electrical energy. This heat energy is converted into electrical energy by a thermoelectric generator. Semiconductor-type thermoelectric materials, maintained in a temperature gradient, accomplish the conversion. The isotopic fuel supplies heat to the thermoelectric materials and sea water acts as the heat sink to maintain the … more

Comparison of finite-element stress analysis with experimental copper sphere impacts. [NONSAP computer code]

Description: Three copper spheres were impacted on targets of varying surface finishes at 100 m/s. Impact face friction was varied for each test and the impact was photographed with a high-speed camera. Postimpact strains and deformation were measured. A finite-element computer code, NONSAP, was used to model the impact. The best agreement between computer prediction and experiment was obtained using isoparametric elements, a graded mesh, and actual high-strain-rate copper stress-strain data. Frictional con… more

Description: Fuel aging studies were performed on the fuel form (plutonium-238 dioxide and yttrium) used in the Milliwatt Generator Radioisotopic Heat Source to determine the possibility of fuel degradation and of the resultant generation of respirable fines. In addition to long-term thermal aging of the fuel, evaluations included the effects of thermal ramping of the aged fuel to 1000/sup 0/C and of impacting thermally hot (450/sup 0/C) heat sources at 150 m/sec after thermal aging.
