ADDITIONAL ANALYSIS OF THE SL-1 EXCURSION. Final Report of Progress, July- October 1962

Description: Work was carried out to obtain significant data on reactor excursions, in particular the SL-1 excursion, to extend the analysis of reactor transient behavior so as to obtain an improved understanding of the thermal and mechanical processes that take place during and following a reactor excursion, and to obtain chemical, metallurgical, and nuclear data relative to the pre-accident performance of the SL-1. Laboratory investigations were made of samples of the SL-1 power plant. Results are given a… more

ANGULAR DISTRIBUTION OF FRAGMENTS FROM FISSION INDUCED BY HEAVYIONS IN GOLD AND BISMUTH

Description: We present the results of measurements of the angular distribution of fission fragments produced by irradiation of Au{sup 197} and Bi{sup 209} with various heavy ions. The projectiles, B{sup 11}, C{sup 12}, N{sup 14}, and O{sup 16}, had energies from a few MeV above the Coulomb barrier to 10.4 MeV per nucleon. The gross features of these results can be explained by use of a model and parameters that have been used by others to account for angular distributions of fission fragments from helium-i… more

CHARACTERIZATION OF UO$sub 2$ POWDERS. Quarterly Report No. 5, October 10, 1961 to January 10, 1962

Description: The particle size distribution of UO/sub 2/ powders gave good eorrelation with the sintered density of pellets. The method involves gravity sedimentation techniques. The green pressing step of pellet fabrication was found to affect the particle size distribution of the UO/sub 2/ powders. The magnitude of this effect is considered in characterization of the pressed powders. (J.R.D.)

Chemical Technology Division, Chemical Development Section C Progress Report for October-December 1961

Description: Recovery of Th (and U) from Granitic Rock. Recovery of Th by acid leaching ten addltlonal granite samples (36 to 82 ppm Th) from the Conway formation in N. H. ranged from about 50 to 85%, and averaged about 70%, Study of the effect of grind size on the recovery of Th from Conway and Plkes Peak granites showed no significant differences in the range minus 20 to minus 200 mesh. The Th concentration in a sized Conway granite sample was found to be much greater in the fine than in the coarse fracti… more

Description of the net return optimization computer program, IBM 7090, Fortran monitor

Description: During the past four years, IBM data processing computers have been utilized to perform countless studies involving the optimization of the HAPO plutonium production complex (RA.PO and off-site supporting plants). During this time, three process optimization models have been constructed and associated Fortran programs have been written. These three are (1) maximum net return, (2) minimum reactor unit cost, and (3) maximum grams. This document will be concerned only with the first program: net r… more

Development of Techniques for Power Production From Mixed Fission Products

Description: "Progress is reported on Phase II of a program for the development of a mixed fission product fueled thermoelectric generator. Materials studies are described in which bonded assemblies of bismuth telluride were life tested up to 3000 hours at 350 to 400 deg F hot junction temperature. Data were too inconsistent to define any satisfactory long-life bonding process. Further work is needed to eliminate the process variables. Insulation studies aimed at determining the thermal conductivity of vari… more

Electrical Properties of the Tungsten Bronzes

Description: From abstract: "The electrical resistivity of NaxWO3, LixWO3, and KxWO3 has been measured at 300°K. The range of x-values was 0.25 < x < 0.9. All resistivities were characteristic of a metal and lie on a single curve. An extrapolation of the conductivity curve to zero conductivity indicated that the tungsten bronzes should be semiconductors for x < 0.25. The resistivities that have been measured for tungsten bronzes with x < 0.25 showed semiconducting behavior. The resistivity of LixWO3 exhibit… more

Electronic Spectra of Catacondensed and Pericondensed Aromatic Hydrocarbons

Description: From abstract: "The electronic spectra arising from the excitations of pi-electrons in homo-nuclear conjugated bond systems are calculated for 37 aromatic hydrocarbons. The theoretical approach used takes into account overlap effects between different a atoms, correlation between different electrons, variations in internuclear distances, and the influence of non-conjugated neighbors, hydrogen and carbon. Four types of approximations are carried trough for the molecules in order to obtain an est… more
