Effects of CTR irradiation on the mechanical properties of structural materials

Description: Mechanical properties of CTR structural materials are important in determining the reliability and economics of fusion power. Furthermore, these properties are significantly affected by the high neutron flux experienced by components in the regions near the plasma of the fusion reactor. In general, irradiation hardens the material and leads to a reduction in ductility. An exception to this is in some complex engineering alloys where either hardening or softening can be observed depending on the… more

Study of efficient high-power, high-energy neutral beams for the Reference Mirror Reactor

Description: An injector design for the Reference Mirror Reactor is described which uses negative ions created by charge-exchange in a cesium vapor cell and neutralized by photodetachment. Some of the innovations discussed include a continuously operating cathode for an LBL/LLL ion source, a negative ion beam line with cooled grids, a high voltage accelerator configuration with insulators shielded from the neutron and gamma flux, and cryopanels which continuously cycle between pumping and outgassing modes.

Determination of permeability of granitic rocks in GT-2 from hydraulic fracturing data

Description: The Los Alamos Scientific Laboratory is currently conducting a study to determine the feasibility to extract geothermal energy from dry hot rock. The investigated concept calls for the creation of a hydraulic fracture in hot, impermeable rock. Heat will be exchanged subsequently at the fracture surface between the rock and a circulating fluid. The successful creation of hydraulic fractures in the granitic section of exploratory holes GT-1 and GT-2 yielded sufficient data to calculate the averag… more

Potentiometric determination of sulfate with EDTA and the cupric-selective electrode

Description: Sulfate was indirectly determined by precipitating sulfate as BaSO/sub 4/ and then dissolving BaSO/sub 4/ in excess ammoniacal EDTA. The excess EDTA was titrated potentiometrically with La/sup 3 +/. A cupric-selective electrode was used to detect the end point. About 10/sup -3/M SO/sub 4//sup 2 -/ was determined in 3M HCl solutions of metal oxides with a relative standard deviation of 3.5 percent and a bias of +4 percent.

Chemistry of the KALC process. The CO/sub 2/--I/sub 2/--CH/sub 3/I--H/sub 2/O system

Description: The chemistry of the CO/sub 2/--I/sub 2/--CH/sub 3/I--H/sub 2/O system in stainless steel has been investigated with respect to the probable reactions of these components in the KALC process. Iodine is stable in dry CO/sub 2/ contained in stainless steel; but in the presence of organic impurities or water, it is lost from solution via reactions which produce solid phases. Methyl iodide, however, is stable in either wet or dry CO/sub 2/ solutions. Distribution coefficients for I/sub 2/ and CH/su… more

Radionuclide content of an exhumed canyon vessel and neighboring soil. [Health hazards from long-time buried radiochemical process equipment]

Description: The long-term hazard potential associated with burial of process equipment from radiochemical separations plants is being evaluated. As part of this evaluation, a feed adjustment tank was exhumed eighteen years after burial. The tank had been in service in the fuel reprocessing plant for twenty-nine months before it was retired. Assay of the exhumed tank indicated that 7 mg (0.4 mCi) of /sup 239/Pu and 1 mCi of /sup 137/Cs remained on its surfaces; 1.1 mg (0.07 mCi) /sup 239/Pu, 0.4 mCi /sup 13… more

Coal technology program progress report for September 1976

Description: In the separations technology work, bench-scale filtrations using coal and char precoats were compared to standard filtrations using diatomaceous earth precoats. In both cases the filtration rates and filtrate clarities were comparable to standard values; thus, considerable economic savings are possible due to the lower cost and substitution of a material readily available, and subsequent recovery of the energy value of the coal or char precoat by gasification. The demonstrated use of the char … more
