Evaluation of extraction chromatography for americium recovery

Description: Extraction, or reverse-phase partition chromatography, as used mostly for analytical separations, employs an organic solvent extractant as a stationary phase on an inert support material. This technique, which has the advantage of utilizing the versatility of solvent extraction systems with the less expensive operation of ion exchange equipment, was evaluated for a process to recover low level concentrations of americium from acidic process waste streams at Rocky Flats. The bidentate organophos… more

Computation of the bounce-average code

Description: The bounce-average computer code simulates the two-dimensional velocity transport of ions in a mirror machine. The code evaluates and bounce-averages the collision operator and sources along the field line. A self-consistent equilibrium magnetic field is also computed using the long-thin approximation. Optionally included are terms that maintain ..mu.., J invariance as the magnetic field changes in time. The assumptions and analysis that form the foundation of the bounce-average code are descri… more

Summary report on salt dissolution review meeting, March 29--30, 1977

Description: It is the unanimous conclusion of the Ad Hoc Committee that radioactive waste can be stored in salt and underground repository sites sufficiently removed from natural and/or man-made dissolution areas so that the waste will not be liberated during its hazardous period at projected rates of future salt dissolution. To ensure long-term isolation of radioactive waste in salt formations, specific recommendations are given for needed research concerning (A) General Principles, (B) Basinal or Regiona… more

Analysis of Lime-Slurry Stirred Tank Carbonation Reactor

Description: Gas residence time distributions were determined for a stirred tank carbonation reactor. Empirical correlations for the first and second moments of the residence time distribution (RTD) curves as functions of flow rates and impeller speeds were obtained. Decontamination factors for /sup 85/Kr were measured.

Progress report for the Division of Safeguards and Security: January--June 1977

Description: Development of the calorimeter equilibrium prediction program has been completed, and tests of the software program have been conducted on calorimeters ranging from 1 to 6 in. (2.5 to 15 cm) in diameter and power inputs between 0.1 and 8.3 W. Equilibrium values have been predicted with relative accuracies of better than 0.1% (95% confidence) and with an average time improvement factor of 2.1, which represents a 52% time saving, for every test case. A computer code is being developed by the Univ… more
