Alpha Fuels Environmental Test Facility impact gun

Description: The Alpha Fuels Environmental Test Facility (AFETF) impact gun is a unique tool for impact testing /sup 238/PuO/sub 2/-fueled heat sources of up to 178-mm dia at velocities to 300 m/s. An environmentally-sealed vacuum chamber at the muzzle of the gun allows preheating of the projectile to 1,000/sup 0/C. Immediately prior to impact, the heat source projectile is completely sealed in a vacuum-tight catching container to prevent escape of its radioactive contents should rupture occur. The impact v… more

Capability of LOFT vital batteries to supply emergency power demands during severe cold weather conditions

Description: This study evaluates the capability of the vital batteries (PPS) to provide electrical power via the vital DC-AC motor generator sets to the LOFT PPS loads during severe cold weather conditions. It is concluded that these batteries while at a temperature of 5/sup 0/F will supply the necessary PPS electrical loads for a time in excess of the one hour permitted to start the diesel generators and are, therefore, adequate at this temperature. This Revision B of the LTR includes revised, more recent… more

Personnel neutron monitoring developments at LLL. [Development and calibration of various types of neutron detectors and monitors]

Description: Approximately 40 employees at LLL work in areas where personnel neutron monitoring is necessary. The dose rate in these areas is low, rarely exceeding 0.5 rem per year. However, the wide variety of neutron environments (dt neutron generators; a 3 MW pool type reactor; a 100 MeV electron Linac; and a number of vaults and glove boxes where alpha, n and spontaneous fission sources are stored) makes the neutron monitoring task difficult. As a result, we have been studying potential developments in … more

Offsite exposure from failure of waste gas processing system piping failure

Description: A calculation has been performed to determine the offsite exposure to the general public in the unlikely event of the failure of Waste Gas Processing System (WGPS) piping. The consequences for this type of accident are limited by DOEM 0524 with an offsite dose of 1.5 REM. As can be seen in this LTR, the doses from this accident are far in excess of the 0524 limits. Also included in this LTR is a calculation of the BST gas space contents vs. time in the event of a WGPS piping failure.

Civilian applications of laser fusion

Description: The commercial aspects of laser fusion were evaluated in an attempt to relate the end products (neutrons and energy) to significant commercial applications. We have found that by far the largest markets and highest payoffs for laser fusion are associated with electric power production. Hence, much of this report evaluates the prospects of producing commercial electricity with laser fusion. To this end, we have described in detail a new and promising laser fusion concept--the liquid lithium wate… more

Biostratigraphic analysis of core samples from wells drilled in the Devonian shale interval of the Appalachian and Illinois Basins

Description: A palynological investigation was performed on 55 samples of core material from four wells drilled in the Devonian Shale interval of the Appalachian and Illinois Basins. Using a combination of spores and acritarchs, it was possible to divide the Middle Devonian from the Upper Devonian and to make subdivisions within the Middle and Upper Devonian. The age of the palynomorphs encountered in this study is Upper Devonian.

Development of advanced methods for continuous Czochralski growth. Silicon sheet growth development for the Large Area Silicon Sheet Task of the Low Cost Silicon Solar Array Project. Third quarterly progress report, March 18--July 14, 1978

Description: Six batch melt-replenishment runs were performed. In the most recent, five crystals were grown with a total through-put of 48 kg. In addition to its stated purpose of developing the growth and recharge process for continuous silicon production, this experimentation has served to prove completely both the concept of charging with granular (viz., niblet) feed and the design of the pellet-feeder/isolation-lock assembly. The design of the prototype Czochralski puller was begun on schedule. Layouts … more

Energy by reverse electrodialysis. Final report

Description: The principles and history of converting the difference between the chemical potentials of concentrated and dilute salt solutions to useful energy by reverse electrodialysis (RED) are discussed. The potential sources of brines discussed include the brines of oil and natural gas fields, the brines from flooding of salt domes, the brines of salt lakes, seawater, and geothermal brines. Equations for predicting the performance of RED units are presented and discussed. A study of the effects of vari… more

Fluorescent scattering by molecules embedded in small particles. Progress report, May 1, 1977--October 31, 1978. [Summaries of research activities at Clarkson College of Technology]

Description: A model for the fluorescence and Raman scattering by molecules that comprise or are embedded in small particles was developed and numerical calculations performed. The emphasis during this first year of the contract was on writing and testing the computer programs necessary for numerical calculations and on demonstrating the extent of the potential effects that the geometrical and optical properties of the particle would have on the Raman and fluorescent emissions. For the purpose of demonstrat… more

Preliminary evaluation of a spherical bragg x-ray crystal

Description: Recently, preliminary measurements were taken to demonstrate the quality of narrow spectral band, two-dimensional imaging of a specially-shaped quartz x-ray diffracting crystal. The evaluation consisted of back-illuminating a fine wire mesh, located off the focal circle of the crystal, with a monochrome of aluminum K radiation and observing the quality of the grid-shadowed pattern diffracted by the crystal. The experiment was performed in a vacuum diffractometer. While the actual spatial resolu… more

Final report, Task 3: possible uses of the Nuclear Fuel Services, Inc. reprocessing plant at West Valley, New York. [For research on alternative fuel cycles, spiking, coprocessing, waste solidification, and recovery of radioactive gases]

Description: The West Valley Plant could readily be used for work on reprocessing of alternative fuels, spiking, coprocessing (including CIVEX), waste solidification, and the recovery of radioactive gases. The plant could be easily modified for any scale between small-scale experimental work to production-scale demonstration, involving virtually any combination of fissile/fertile fuel materials that might be used in the future. The use of this plant for the contemplated experimental work would involve lower… more

Corrosion of steel tendons in concrete pressure vessels: review of recent literature and experimental investigations

Description: The fundamentals of localized corrosion are briefly discussed, and the literature concerning corrosion of carbon steel in aqueous environments, in particular the stress-corrosion cracking of carbon steels, is reviewed. The behavior of high strength steels in specific environments, including concrete and organic substances, is also summarized. The available information indicates that the corrosion of steels in correctly formulated concrete is minimal. Even appreciable concentrations of chloride,… more

Limitations of rock mechanics in energy-resource recovery and development

Description: Rock-mechanics problems which limit energy-resource recovery and development are assessed. The most serious limitations were found in the fields of geothermal exploration, mining and in-situ recovery, nuclear-waste disposal, oil and gas recovery, underground storage, and under-ocean tunneling. Recommendations include research to determine and predict porosity, permeability, and fluid flow in situ; research to develop better methods for determining and obtaining shallow and deep in situ stresses… more

Condensed molecular beam as gas target for antiprotons in the SPS

Description: With condensed molecular beams of hydrogen as described in literature, very well defined high local gas densities can be produced, which for antiproton beams of 5 x 10/sup 11/ give luminosities between 10/sup 30/ and 10/sup 31/ cm/sup -2/ sec/sup -1/, two orders of magnitude higher than the luminosity estimates for p-anti p physics in the ISR (10/sup 28/ to 10/sup 29/) and one order of magnitude higher than the luminosity for p-anti p physics in the SPS. After some minor modifications, the same… more
