CHEMICAL ENGINEERING DIVISION SUMMARY REPORT FOR OCTOBER, NOVEMBER, AND DECEMBER 1956

Description: A study of mass transfer in a continuous-flow mixing chamber, fluoride volatilization separations process, corrosion testing in fused fluoride systems, behavior of Pu during volatilization of UF/sub 6/, preparation of PuF/sub 6/ by fluorination of PuF/sub 4/, particle size distribution and U content of UF/sub 4/ , stoichiometric behavior of the reaction IF/sub 5/ + F/sub 2/ + I/sub ignition data on stainless steel, were reported. Studies were continued on the analysis of crude green salt from U ore concentrates, fluidized-bed green salt pilot plant, calcination of reactor fuel wastes, reactor chemistry, chemical- metallurgical separation processes, waste processing operations, and the operation of the gammairradiation facility.

ELECTRONIC SPECIFIC HEAT OF SODIUM TUNGSTEN BRONZE

Description: The design and operation of a calorimeter for use in the temperature range 1.8 to 4.2 deg K are presented, and the methods used in the treatment of data and calculation of results are discussed. The heat capacities of several Na- W bronzes (Na/sub x/WO/sub 3/) were determined in the temperature interval 1.8 to 4.2 deg K. Samples having x equal to 0.89, heat capacities are described adequately by the sum of two terms, one linear and one cubic in temperature. The electronic specific heat of each sample is obtained by evaluating the coefficient of the linear term, and the Rebye eharacteristic temperature derived from the coefficient of the cubic term. Rensities of one-electron energy levels at the Fermi energy, and effective electronic masses are calculated from the electronic specific heats. A plot of the density of states as a function of energy can be made if it is assumed that this curve is independent of Na concentration. The justification of this assumption is discussed in the light of current theories of the solid state. The density of states curve rises rapidly at higher energies, and this rise is interpreted in terms of the filling of a Brillouin zone or of an overlap of two bands. (auth)

FLOW OF AN AQUEOUS SLURRY THROUGH A VERTICAL TUBE

Description: The upward vertical flow of a slurry was investigated utilizing photographic techniques with the intention of obtaining data on solid phase concentration and velocity distribution and to evaluate the use of photography as a tool in slurry analysis. An annalytical expression for tbe ratio of the specific weight of the mixture in tbe tube to the specific weight of the mixture discharged was derived and used to verify certain assumptions indicated in the photographic study.

On the Operator Approach to the Problem of Stability of Difference Schemes and the Convergence of Certain Iteration Procedures

Description: A number of considerations related to the stability of certain difference analogs of the differential equation of heat conduction and with the convergence of iteration procedures derived from implicit difference equations are presented. The operator approach is used in a manner which dispenses with the knowledge of eigenvalues. (J.R.D.)
