Diffusion estimation for small emissions. Preliminary report

Description: A simplified approach is presented to the calculation of ground level concentrations of effluents from small industrial and fuel burning installations. It is intended to serve as a first approximation to a very complex process. Because each stack, building, and terrain configuration is different, actual ground concentrations may frequently differ from the values calculated here by a factor of two. Nonetheless, this procedure should be useful for determining whether ambient air quality standards… more

LIQUID XENON FILLED WIRE CHAMBERS FOR MEDICAL IMAGINGAPPLICATIONS

Description: In 1968, Luis Alvarez suggested that a high-resolution multiwire particle detector could be developed using a thin layer of liquified noble gas as the detection medium. After key problems in chamber construction, purification, and readout had been solved, a spatial resolution of 15 {micro} rms was demonstrated. Work is in progress to build high-resolution chambers and measure their properties for particle physics experiments at high-energy accelerators. The liquid xenon multiwire chamber also h… more

Loft Heater Pin Thermocouple Attachment Testing. Heater Rod Blowdown Tests

Description: Blowdown/reflood testing of two heater rods containing laser welded thermocouple attachments is described. Two series of tests were conducted, one of three and another of nine blowdowns. Test parameters were controlled such that the blowdown/reflood cycles duplicated those predicted for the LOFT reactor. Thermocouple performance throughout the test series was very good in that the only failures observed were caused by bowing of the heater rod. Data from all tests are included as are photographs… more

pi. /sup +/p,. pi. /sup +/n, and. pi. /sup +/d interactions. A compilation. Part II. [Authors, title, abstract, references, beam, momentum, target, data tables, techniques]

Description: A listing is presented of the 297 articles from which the data in Part I were abstracted. These listings contain additional information on each of these articles: authors, title, abstract, closely related references, beam, momenta of experiment, target, etc. One also gives tables of the data as they appeared in the original articles. Systematic comments are made specifying how the final data were obtained; for example, mass cuts for resonance production cross sections, spectator momentum cuts, … more

An Investigation of Metallurgical Factors Which Affect the Fracture Toughness of Ultra High Strength Steels

Description: The relationship between microstructure, heat treatment and room temperature fracture toughness has been determined for the low alloy ultra-high strength steels 4130, 4330, 4340, 4140 and 300-M. Optical metallography, microprobe analysis, and scanning electron microscopy were used to characterize the structure and morphology, while both Charpy V-notch impact tests and plane strain fracture toughness tests were used to determine the fracture properties. The normal commercial heat treatment resul… more

Influence of machine organization on algorithms

Description: A comparative analysis of the CDC STAR-100 and the ILLIAC IV for a given code is given. A large two-dimensional Lagrangian hydrodynamic model for the STAR-100 computer was programmed. Some theoretical considerations concerning execution rates are Presented. Some examples are given of where these theoretical considerations were important considerations in the design of the algorithms. Finally, several observations and opinions, many of which may be controversial but which should be considered by… more

Seismic refraction exploration for engineering site investigations

Description: The theory and practice of using the refraction seismograph for shallow, subsurface investigations is summarized. This is 1ntended to be a guide to the application of the technique and not a comprehensive analysis of every aspect of the method. The fundamentals are presented and their use in time-intercept calculations and interpretations using delay times are discussed. The limitations of this exploration tool are discussed, and other applications of the equipment, such as uphole surveys, are … more

Uncertainties in the analysis of plutonium fueled light water moderated assemblies

Description: A theoretical analysis of UO/sub 2/-- PuO/sub 2/ fueled, light-water- moderated lattice experiments has been performed to aid in establishing technical bases and design criteria for the utilization of plutonium bearing fuel in thermal power reactors. Results for UO/sub 2/ and Al-- Pu lattices are included in order to understand the effects due to uranium and plutonium separately. The problems involved in calculating high leakage critical experiments are discussed. Estimates of the effects of va… more

Radioecology of Some Natural Organisms and Systems in Colorado. Eleventh Technical Progress Report, May 1, 1972--April 30, 1973

Description: The broad purpose of this research is to provide information on the behavior of radionuclides in, and radiation sensitivity of, selected organisms and natural ecosystems in Colorado. Components of alpine tundra, montane forests, shortgrass plains, and freshwater lakes and streams are currently under investigation with respect to behavior and effects of radionuclides. Data are presented from studies on the content of /sup 238/Pu and /sup 239/Pu in samples of soil, litter, vegetation, and tissues… more
