Annual progress report

Description: A single-mode, nonlinear analysis of the 2XIIB experimental results is under development. A Model-I (infinite geometry, no mirror losses or source beams) analysis is nearly complete. Model II (mirror losses, beams, energy drag) is in progress. Nonlinear analysis of the 2..omega../sub p/ instability near the quarter-critical point in an inhomogeneous plasma is continuing.

Brayton-cycle heat-recovery-system characterization program. Gas-conditioning final evaluation report

Description: Flue gas conditioning approaches for the Brayton-cycle heat recovery system are discussed. This revision incorporates the results of recent AiResearch tests on the subatmospheric system (SAS) turbocompressor, as well as the Electric Power Research Institute sponsored tests on ceramic fiber filters. The two primary purposes of the gas conditioning evaluation are: to determine the need for protecting the Brayton-cycle turbocompressor and heat exchanger from the potential damaging effects of erosion and deposition, and to determine what type of approach should be used for cleanup, if protection by flue gas conditioning is required.

Brayton-cycle heat recovery-system characterization program. Subatmospheric-system test report

Description: The turbine tests and results for the Brayton cycle subatmospheric system (SAS) are summarized. A scaled model turbine was operated in the same environment as that which a full-scale SAS machine would experience from the hot effluent flue gas from a glass container furnace. The objective of the testing was to evaluate the effects of a simulated furnace flue gas stream on the turbine nozzles and blades. The following specific areas were evaluated: erosion of the turbine nozzles and blades from the dust in the flue gas, hot corrosion from alkali metal salts in the dust and acid vapor (sulfur trioxide and hydrogen chloride) in the flue gas, and fouling and flow blockage due to deposition and/or condensation from the flue gas constituents.

Ceramic phases for immobilization of /sup 129/I. [Sodalite and boracite]

Description: Materials for ultimate disposal of /sup 129/I have been studied. At present, iodide-sodalite, though not ideal, appears to be the best material for /sup 129/I immobilization from the aspects of ease of preparation, thermal stability, cost of materials, and leach resistance. Good consolidation of the material was achieved by sintering in air at 1000 to 1200/sup 0/C, but the iodine content was significantly below stoichiometric expectations. Hot aqueous media preferentially removed iodine, apparently by OH/sup -/ substitution in near-neutral solutions, and I reversible reaction Cl/sup -/ exchange occurred in brine. Alternation of the sodalite also took place. Soxhlet leach rates were about 5 x 10/sup -4/ g/cm/sup 2/-day by total weight loss, but physical weathering contributed significantly to this value. Moderate doses of radiation had no observable deleterious structural effects. Iodoboracites seemingly cannot be prepared by ceramic or nonhydrothermal wet chemical techniques. Fe-iodoboracite has inferior thermal stability to iodide-sodalite and was completely altered to hematite after treatment at 200/sup 0/C in deionized water. Silver zeolites retained some iodine in the form of crystalline ..cap alpha..-AgI at temperatures up to 1300/sup 0/C even though heating above approx. 700/sup 0/C altered the alumino-silicate framework. However, some of the iodine appeared to be present as soluble iodine, even in heated materials. Treatment at 200/sup 0/C in deionized water or 2M NaCl significantly decreased the crystallinity of the aluminosilicate framework and the ..cap alpha..-AgI reflections in the x-ray patterns were enhanced. Mild ..gamma.. irradiations (approx. 50 MR) affected the x-ray diffraction patterns of some of the zeolites. Various lead oxyhalides had very poor thermal stability.

Northern Marshall Islands Radiological Survey: Sampling and Analysis Summary

Description: A radiological survey was conducted in the Northern Marshall Islands to document reamining external gamma exposures from nuclear tests conducted at Enewetak and Bikini Atolls. An additional program was later included to obtain terrestrial and marine samples for radiological dose assessment for current or potential atoll inhabitants. This report is the first of a series summarizing the results from the terrestrial and marine surveys. The sample collection and processing procedures and the general survey methodology are discussed; a summary of the collected samples and radionuclide analyses is presented. Over 5400 samples were collected from the 12 atolls and 2 islands and prepared for analysis including 3093 soil, 961 vegetation, 153 animal, 965 fish composite samples (average of 30 fish per sample), 101 clam, 50 lagoon water, 15 cistern water, 17 groundwater, and 85 lagoon sediment samples. A complete breakdown by sample type, atoll, and island is given here. The total number of analyses by radionuclide are 8840 for /sup 241/Am, 6569 for /sup 137/Cs, 4535 for /sup 239 +240/Pu, 4431 for /sup 90/Sr, 1146 for /sup 238/Pu, 269 for /sup 241/Pu, and 114 each for /sup 239/Pu and /sup 240/Pu. A complete breakdown by sample category, atoll or island, and radionuclide is also included.

Preparation and properties of SYNROC D containing simulated Savannah River Plant high-level defense waste

Description: We describe in detail the formulation and processing steps used to prepare all SYNROC D samples tested in the Comparative Leach Testing Program at the Savannah River Laboratory. We also discuss how the composition of the Savannah River Plant sludge influences the formulation and ultimate preparation of SYNROC D. Mechanical properties are reported in the categories of elastic constants, flexural and compressive strengths, and microhardness; thermal expansion and thermal conductivity results are presented. The thermal expansion data indicated the presence of significant residual strain and the possibility of an unidentified amorphous or glassy phase in the microstructure. We summarize the standardized (MCC) leaching results for both crushed Synroc and monoliths in deionized water, silicate water, and salt brine at 90/sup 0/C and 150/sup 0/C.

Advanced Selenide Thermoelectric Development Program. Final Report

Description: The primary objective of this work was to demonstrate that copper silver selenide and TAGS could be segmented. The hot junction temperature was planned to be 725/sup 0/C with the segmentation temperature at 400/sup 0/C, both temperatures were selected to prevent excessive sublimation from the hot ends of the segments, respectively. The program was planned as a cooperative effort between General Atomic company and Teledyne Energy Systems. Accordingly, General Atomic synthesized the CuAgSe that was used to fabricate the test hardware that was ultimately delivered to General Atomic for testing. Both the CuAgSe and TAGS were hot pressed in an argon atmosphere then the segments were furnace-bonded to each other. A secondary objective was to produce CuAgSe powder by rapid solidification.

Effect of non-adiabaticity of alpha particles in the axisymmetric cusp TMR

Description: One of the end plug configurations we have investigated for use in a tandem mirror reactor is the axisymmetric cusp. We show that because of non-adiabaticity, the containment of 3.5 MeV alpha particles in this configuration is insufficient for the attainment of acceptable plasma performance.

Exact calculations of nuclear-recoil energies from prompt gamma decays resulting from neutron capture

Description: The results of an accurate determination of the recoil spectrum from (n, ..gamma..) reactions in molybdenum are presented. The recoil spectrum has been calculated from nuclear level structure data and measured branching ratios. Angular correlations between successive gammas have been accounted for using the standard theoretical techniques of Racah algebra and the density matrix formalism.
