Temperature Distributions in Electron Beam Welding Cavities

Description: Surface temperatures in electron beam welding cavities in stainless steel 304 and aluminum 1100, 2024, and 6061 were measured with a narrow band infrared radiation pyrometer. A special device was designed for mounting the radiation-sensing probe next to the electron beam gun in the welding chamber. This mounting device included a mechanism for oscillating the probe so as to scan the cavity region both perpendicular and parallel to the welding direction. At the center of its movement the probe v… more

The effects of moisture on the microstructure of cement-based materials

Description: New experimental techniques that allow the precise measurement of drying shrinkage of cement-based materials within the Environmental Scanning Electron Microscope have been developed. Accuracies of approximately 1% can be obtained on images as small as 20 {times} 20 pixels. Preliminary results on the shrinking of these materials has been obtained and quantitatively analyzed to produce maps'' of the deformation process. Samples have been dried from saturation in environments which a approximatel… more

Uranium miner lung cancer study. Progress report, July 1, 1975--July 1, 1976

Description: This study on the rate of lung cancer development in uranium miners was initiated in 1957 by the U. S. Public Health and many facets of this project are reaching final objectives. Many new studies have developed in the course of this study and will continue. The projects supported by The Energy Research and Development Administration are of utmost importance and consist of: collection of material from uranium miners known to have cancer of the lung into a tumor registry; manual on pulmonary cyt… more

Conceptual design report for the Solenoidal Tracker at RHIC

Description: The Solenoidal Tracker At RHIC (STAR) will search for signatures of quark-gluon plasma (QGP) formation and investigate the behavior of strongly interacting matter at high energy density. The emphasis win be the correlation of many observables on an event-by-event basis. In the absence of definitive signatures for the QGP, it is imperative that such correlations be used to identify special events and possible signatures. This requires a flexible detection system that can simultaneously measure m… more

Energy and protein production from pulp mill wastes. Progress report, September 15, 1976--December 15, 1976

Description: Significant progress was made during the past quarter in establishing the operability and reliability of major pieces of equipment needed for the production of protein and methane from spent sulfite liquor (SSL). Batch ozonations of SSL were conducted at times varying from 1 to 6 hours at pH's in the range of 10 to 2. These screening experiments consistently indicate that low ph's favor the breakdown of SSL into organic fragments which are more easily assimulated by micro-organisms. Approximate… more

CTR plasma engineering studies. Progress report, 1 September 1975--30 Jun 1976

Description: During the past contract period, this research has been concerned with three principal tasks, namely: (1) Fusion-product studies. The primary objective of this work is to study potential effects (e.g. instabilities, changes in heating profile and wall loadings, etc.) caused by high-energy fusion products. A second objective is to establish the operating conditions and measurements required for use of D-/sup 3/He in early experiments such as TFTR to simulate D-T burns. (2) Mirror system studies.… more

Atmospheric dispersion and noise propagation at Imperial Valley Geothermal Fields

Description: Quantitative estimations are made for the atmospheric dispersion of gases, heat, and noise due to geothermal energy sources in Southern California's Imperial Valley. In particular, gas concentration per unit source strength, change in mixing ratio, relative humidity, temperature, and the ratio of heat flux to solar constant are calculated. The possibility of atmospheric refraction of source noise is also considered.

Inborn anemias in mice. Progress report to accompany twenty-first renewal proposal, 1 May 1975--30 April 1976

Description: Progress is reported on studies on hereditary anemias of mice. At present under study are four macrocytic anemias, four hemolytic anemias, nonhemolytic microcytic anemia, transitory siderocytic anemia, sex-linked iron-transport anemia, and the autoimmune hemolytic anemia of NZB. Each of these blood dyscrasias is caused by the action of a unique mutant gene, each of which determines the structure of different intracellular molecules, and thus controls a different metabolic process. Thus our wide… more

LIMB Demonstration Project Extension

Description: The basic goal of the Limestone Injection Multistage Burner (LIMB) demonstration is to extend LIMB technology development to a full-scale application on a representative wall-fired utility boiler. The successful retrofit of LIMB to an existing boiler is expected to demonstrate that (a) reductions of 50 percent or greater in SO and NO emissions can be achieved at a fraction of the cost of add-on FGD systems, (b) boiler reliability, operability, and steam production can be maintained at levels ex… more

Maximization of energy in the output of a linear system. [LOPAS]

Description: A time-limited signal which, when passed through a linear system, maximizes the total output energy is considered. Previous work has shown that the solution is given by the eigenfunction associated with the maximum eigenvalue in a Hilbert-Schmidt integral equation. Analytical results are available for the case where the transfer function is a low-pass filter. This work is extended by obtaining a numerical solution to the integral equation which allows results for reasonably general transfer fun… more

The solubility of uranium hexafluoride in perfluoroethers

Description: The polyperfluoroethers are compatible with uranium hexafluoride (UF/sub 6/) and are suitable for use in diffusion pumps and in mechanical vacuum pumps which rely on oil as both the lubricant and the seal. The UF/sub 6/ is soluble in all fluids with which it is compatible. Because a number of vacuum pumps in the BOP facilities of the GCEP plant employ these perfluoroether oils as the working fluid and have oil chambers which are large, questions have been raised as to the relationships governin… more

Final report on a calculational parameter study of soils typical of some ESSEX I cratering sites

Description: The one-dimensional computer calculations described in this report were performed to simulate stress-wave propagation and kinetic energy transfer associated with subsurface cratering detonations in soils. A hypothetical 20-ton-yield nuclear explosive was assumed as the energy source, surrounded by a single soil material. Various soil descriptions were selected in order to systematically study the range of soil response to the nuclear detonation. The soils were representative of the layered mixt… more

Slifers revisited: a method for determining yields independent of radiochemical measurements

Description: It would be very desirable if an independent method other than radiochemical measurement were available to determine the yields of low-yield events in the alluviums and tuffs of areas 2, 9, and 10 at the Nevada Test Site. The successful application of slifers to the measurement of yields from high-yield events suggests that under some conditions they may also be usable with low-yield events. This view is supported by the evidence discussed here, which is based on direct experience with slifer y… more
