An Ultrasonic System for Testing Isotope Heat Capsules

Description: Introduction: This report describes a program to develop a nondestructive (ultrasonic) tester and testing procedure to perform integrity tests on isotope heat source containers. The increased application of isotope heat sources has brought more attention to the engineering problems encountered during fabrication. One of the most important of these problems is insuring the isotope containment during the long unattended periods of use. To determine the integrity of the heat source container, a no… more

Trafficability of Soils: Eighteenth Supplement, Development of Revised Mobility Index Formula for Self-Propelled Wheeled Vehicles in Fine-Grained Soils

Description: The main purposes of this study were to (a) obtain adequate test data to determine experimentally the vehicle cone index (VCI) for 50 passes for vehicles mounted with nonconventional tires and (b) use results of the field tests to develop a revised mobility index (MI) formula for self-propelled wheeled vehicles.

Playa Surface Morphology: Miscellaneous Investigations

Description: Abstract: Numerous environmental processes affect the development and stability of playa (lakebed) surfaces. Of special significance are hydrologic processes that control the amount and flow of both surface and ground water, and climatic variations which in turn influence the hydrology. This report, in six parts, examines some aspects of the playa surface environment. Chapter 1 is an introduction. Chapter 2 describes microrelief changes that developed at Harper Playa, California, following floo… more

Oscillator Strengths and Transition Probabilities fro 3288 Lines of Fe I

Description: Report of a homogeneous set of intensity-related data calculated for 3288 spectral lines of Fe I in the region from 2100 to 9900 angstroms. The quantities tabulated in the present monograph include log (g__), log (gf), gf,f,gA, and A. Since recent investigations do not support excitations corrections in the case of Fe I and certain other spectra, the present tabulation incorporates a removal of that normalization function. This recalculation affects the values for all lines whose upper energy l… more

Design and Testing of a High-Heat Flux Electron-Bombardment Heater

Description: Report issued by the Argonne National Laboratory discussing the testing of an electron-bombardment heater. As stated in the abstract, "the applications of electron-bombardment heating to liquid-metal heat transfer and reactor safety experiments are discussed. The design of a high-heat-flux, electron-bombardment heater (EBH) is presented" (p. 7). This report includes tables, illustrations, and photographs.
