Actinide recovery from combustible waste: the Ce(IV)-NHO/sub 3/ system. Final report

Description: Actinides in ash can be leached effectively by refluxing with Ce(IV) in HNO/sub 3/; solubilization of actinide in ash was greater than or equal to 95% at ash concentrations to 30 g/l in stirred leachant. Plutonium and americium were the actinides present in the ash. Solubilized plutonium and americium were recovered from Ce(IV)-HNO/sub 3/ solution by solvent extraction. Extraction of plutonium into 30% tributyl phosphate in n-dodecane gave 99.99% recovery. The plutonium-depleted solution was th… more

Alternative oxidizers for strip coal mine blasting agents. [Including study of possible substitutes; 53 references]

Description: Since ammonium nitrate manufacture is dependent on natural gas, a shortage in natural gas could lead to a critical shortage in coal by limiting the availability of ammonium nitrate for blasting. The purpose of this study was to assess the future availability of ammonium nitrate and to evaluate the potential of alternative oxidizers not dependent upon natural gas for use in blasting agents. Increased storage capacities and rapidly increasing levels of relativey cheap imported ammonia appear to e… more

Capture cross section and gamma-ray spectrum calculations for medium-weight nuclei. [Double-peak, energy-dependent Breit-Wigner model]

Description: A double-peak, energy-dependent Breit-Wigner model of the E1 gamma-ray strength function was applied to nuclei from As to Rh, to predict their neutron capture cross sections and capture gamma-ray spectra. A consistent set of model parameters was obtained in this mass region to describe the step in the low-energy tail of the E1 strength function. This step allows agreement with photonuclear data at high energies, the correct GAMMA/sub gamma/ to be obtained for agreement with neutron capture cros… more

Carbide Precipitation in the Heat Affected Zone of a GTA Weld in 21-6-9 Stainless Steel.

Description: Grain boundary precipitation was observed in a multipass GTA weld in 21-6-9 stainless steel. The precipitate was identified bby electron diffraction as Msub23 Csub6-type carbide. The presence of these carbide particles did not cause intergranular attack in standard corrosion tests.

Cell and stack design alternatives. Second quarterly report, November 1, 1978-January 31, 1979

Description: Progress on a program to develop commercially viable phosphoric acid fuel cell driven on-site integration energy systems is presented. A mass and energy balance was completed for one operating point of a selected power generation sub-system with a power output of 119 kW. Potentially, 87% of the LHV of the input fuel is available as bus bar electricity or useful heat. A 2 kW stack of conventional design and a 0.5 kW DIGAS cooled stack have been constructed and are on test at ERC. Renovation of a… more

Characterization of nuclear waste

Description: Nuclear wastes which are logical candidates for deep geologic disposal include commercial (spent fuel, reprocessing) and defense wastes. It is expected that the 5250 metric tons of spent fuel discharged through the end of 1978 would increase to about 100,000 tons by the end of 2000. The individual characteristics of each waste type (spent fuel, solidified waste, defense wastes) are described in turn. (DLC)
