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 velocity delivered by this gas-powered gun can be regulated to within +-2%.

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, and complete technical data relating to MG set efficiency, battery operating procedures and cold temperature derating. Revision B supersedes and replaces all previous issues.

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 personnel dosimetry and neutron field monitoring, particularly as they relate to proposed changes in the neutron quality factor and the implied reduction in allowable dose limits.

A weekly publication, the Texas Register serves as the journal of state agency rulemaking for Texas. Information published in the Texas Register includes proposed, adopted, withdrawn and emergency rule actions, notices of state agency review of agency rules, governor's appointments, attorney general opinions, and miscellaneous documents such as requests for proposals. After adoption, these rulemaking actions are codified into the Texas Administrative Code.

A two year design study has been completed for medical ion accelerators with beams of sufficient range and intensity for therapy. The particles of main interest were ions between carbon and neon, but the generation of proton and neutron beams was studied also. Cyclotrons appear to be good injectors for a heavy ion medical synchrotron, particularly if neutron and/or isotope production is desired as well. They also offer a competitive solution for proton beams of 250 MeV. A superconducting cyclotron design for 380 MeV/u carbon was worked out, but a synchrotron for heavy ion beams of 400 to 600 MeV/u and 5 x 10/sup 9/ particles/sec was found to be more economical and flexible.

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.

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 waterfall reactor. In addition, we have taken the most attractive features from our laser fusion studies and used them to compare laser fusion to other long-range sources of energy (breeder reactors and solar energy). It is our contention that all three sources of electrical energy should be developed to the point where the final selections are primarily based on economic competitiveness. The other potential applications of laser fusion (fissile fuel production, synthetic fuel production, actinide burning, and propulsion) are also discussed, and our preliminary plan for the engineering development of laser fusion is presented.

An analytic calculation of the cooling by thermal conduction of a hot, cylindrically symmetric gas bubble is presented. The results are in good agreement with an exact numerical calculation. 1 figure, 4 tables.

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.

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 of all major components have been prepared, and detailing is currently in progress; bills of material for long-delivery items were released to Manufacturing in June. Two critical components have already undergone advance trials: the recharging mechanism, which has been in use for four months, and the crystal lift mechanism, which has been bench-tested and is to be mounted on the laboratory Varian 2850 puller. Further, the fabrication of the transducer/control assembly - the automation system - has been accelerated in order to permit testing and preliminary process development on the 2850 furnace prior to the completion of the prototype puller. The SAMICS analysis of ingot growth and wafering has been completely revised and has been extended to 1986.

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 variables on power output from RED cells is given, and estimates of capital and operating costs of RED power units are detailed. (WHK)

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 demonstrating effects emphasis was focused upon the case of isotropically polarizable molecules that fluoresce or Raman scatter through electric dipole transitions. Some preliminary results are described. One result of these investigations that is of particular significance for remote sensing of pollutants is that it would be a serious mistake to use inelastic scattering techniques such as Raman and fluorescent scattering for quantitative assay of specific molecules in aerosols containing particulates without taking into account the size, structure and refractive index of the particles. A list of publications is included.

The implementation of a nuclear waste management technology raises several issues concerning the regulation of social risk. This paper presents a decision analytic approach to resolving some of those issues. A methodology for developing a radiological risk measure is presented, and several approaches to defining acceptable levels of that risk measure are considered. The methodology presented is oriented toward the development of radiological performance objectives for use as guidance in the drafting of regulations.

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 resolution limit of the crystal was not measured, this limit is demonstrated to be significantly less than 50 microns.
