Cleanex process: a versatile solvent extraction process for recovery and purification of lanthanides, americium, and curium

Description: At a concentration of 1 M in straight-chain hydrocarbon diluent, HDEHP will extract americium, curium, and other trivalent actinide and lanthanide elements from dilute acid or salt solutions. The solute is back-extracted with more concentrated acid, either nitric or hydrochloric. The process has been used in the continuous, countercurrent mode, but its greatest advantage arises in batch extractions where the excess acid can be titrated with NaOH to produce a final acidity of about 0.03 M. Under… more

Evaluation of the effect of break nozzle configuration in loss-of-coolant accident analysis

Description: The Semiscale Mod-1 test program has utilized two different break nozzle configurations in a test facility with identical initial and boundary conditions. An evaluation has been made to determine the effect these break nozzle configurations have on system thermal-hydraulic response during a 200% double-ended cold leg break loss-of-coolant accident simulation. The first nozzle had a convergent-divergent design; the second nozzle had a convergent design with an elongated constant area throat foll… more

Interactive programs for low-flow frequency analyses for use in regional studies

Description: Seven-day ten-year low-flow values have been used as indices of water availability for regional energy facility siting. This paper describes an automated system for generating low-flow frequency distributions for United States Geological Survey streamflow gaging sites. Since no single frequency distribution will match the low flow frequencies at all stream gaging stations, it is necessary to examine several possible distributions for each station to determine the most useful one. Four represent… more

Laboratory scale glass melter for testing defense waste glass

Description: A one-liter joule heated glass melter was built to test the applicability of continuous melting to simulated high-level calcined defense waste. Inconel 690 electrodes and K-3 refractory brick were chosen for their corrosion resistance to fluoride glass. The melter maintained a full melt at 1100/sup 0/C using 3 kW. After approximately 2 months of operation, the melter was dismantled for metallurgical examination. The Inconel 690 electrodes were heavily corroded. A second melter is now in operati… more

Nondestructive assay of subassemblies of various spent or fresh fuels by active neutron interrogation

Description: Recent studies show that subassemblies containing various spent fuels could be assayed rapidly and accurately by a nondestructive assay system using active neutron interrogation and prompt-neutron detection. Subassembly penetration is achieved by 24-keV (Sb--Be) interrogation neutrons; the spent-fuel neutron background is overridden by using strong interrogating sources and prompt-neutron signals, and background gammas are absorbed by lead. Experiments have demonstrated the potential for assayi… more

Reforestation of borrow pits by use of specific mycorrhizal fungi, soil amendments, and site preparation. [A borrow pit is an excavation from which materials (earth) are removed to be used as fill at another location]

Description: Second-year results are presented from three separate studies concerned with reclamation of borrow pits using specific mycorrhizal fungi and various soil amendments. Study I demonstrates that container grown loblolly pine (Pinus taeda) seedlings inoculated with certain ectomycorrhizal fungi respond to soil amended with sewage sludge, but not to inorganic fertilizer applied at a rate of 500 lbs/acre of 10-10-10. In Study II, the average volume of nursery produced loblolly pine seedlings is great… more
