The Electrical Resistivity of Liquid Sodium and Dilute Sodium Alloys. Final Report

Description: "The factors of atomic size, ion core potential, and charge, which contribute to the increment in electrical resistivity produced by solutes in metallic solutions, were separated and experimentally evaluated in liquid sodium. The results are expressed in a semi-empirical relationship which defines the increment in resistivity of a monovalent solution as the sum of the fractional difference in atomic volume of solute and solvent and the difference in atomic number of Na and the solutes Li, K, Cs… more

An approach to the study of solid state bonding

Description: The program objective has been to investigate the possible similarity between a bond interface and a grain boundary. The criterion for establishing the similarity of a bond interface and a grain boundary was the migration characteristics of the boundary under the influence of controlled orientation, strain level, temperature and time. In addition, the orientation dependency of the "threshold", or minimum deformation, for bonding would have to be determined. The initial bonding studies were to … more

The Pebble Bed Reactor Program

Description: Several different types of experimental facilities have been evaluated to determine the most suitable and economical means of demonstrating the technical feasibility of the Pebble Bed Reactor concept. The criteria for demonstrating technical feasibility are: 1) bulk irradiation of fuel elements in order to obtain statistical data on performance, 2) Maintenance of system activity at specified levels, and 3) Feasible maintenance procedures. An additional criterion, which is required to achieve b… more

Interpretation of Westwood, New Jersey Rainfall Data

Description: "Progress is reported in an evaluation of fission product concentration in rain as a function of time, location, and meteorological setting. Data on rainfall collected at Westwood, N. J., were analyzed for information on the mechanisms of fallout deposition, seasonal variations in fallout, the stratospheric residence time of W/sup 185/ resulting from Operation Hardtack, and the accuracy of pot samplers for sample collection. Data from other collection stations were also analyzed for consistency… more
