We are using a transponding geostationary satellite to collect surface environmental data to describe the fate of soil-borne radionuclides. The remote, former atomic testing grounds at the Eniwetok and Bikini Atolls present a difficult environment in which to collect continuous field data. Our land-based, solar-powered microprocessor and environmental data systems remotely acquire measurements of net and total solar radiation, rain, humidity, temperature, and soil-water potentials. For the past year, our water flux model predicts wet season plant transpiration rates nearly equal to the 6 to 7 mm/d evaporation pan rate, which decreases to 2 to 3 mm/d for the dry season. Radioisotopic analysis confirms the microclimate-estimated 1:3 to 1:20 soil to plant /sup 137/Cs dry matter concentration ratio. This ratio exacerbates the dose to man from intake of food plants. Nephelometer measurements of airborne particulates presently indicate a minimum respiratory radiological dose.

Research into deuterium-from-protium isotope separation via both metal hydride chromatography and CO/sub 2/ laser multiple-photon dissociation (MPD) of trifluoromethane (CDF/sub 3//CHF/sub 3/) is discussed. Several new classes of alloy compositions, including Mg-rare earth, NiTi/sub x/, and (Ca+Ce,Zr,Ti)./sub 8//sup -/Ni/sub 4/Cu compounds, were evaluated for chromatograhic isotope separation; no tested alloy exhibited properties suitable for commercial deuterium separation. For deuterium separation by MPD of CDF/sub 3/, construction of a CO/sub 2/ laser system was completed that is capable of delivering either 2 nsec short pulses at a single wavelength or 200 nsec long pulses simulatneously at two different laser frequencies. The wavelength dependence of single-line multiple-photon dissociation probability of CDF/sub 3/ was measured, and is reported here. Deuterium separation by CO/sub 2/ laser photolysis of CDF/sub 3//CHF/sub 3/ near 10.3 ..mu.. using approx. 2 nsec pulses still appears to be a commercially viable process for heavy water production.

The laboratory facility for photochemical tritium separation research has been completed. Methods for synthesizing the mono-tritiated halogenated methanes have been developed. Notably, CTF/sub 3/ has been synthesized and spectrally analyzed. The CTF/sub 3/ vibrational frequencies are found to be in quite good agreement with earlier calculations.

The fluid motion in the cavity of a HYLIFE reactor was calculated for the two extreme cases of optically thin and thick lithium gas in the hot core. The distinction is important because in the optically thin case (emission approximation) a major fraction of the gas energy is re-radiated to the main fall, following the lithium implosion, whereas in the optically thick case (diffusion approximation) virtually none escapes. This, in turn, has a major influence on the impulse ultimately imparted to the reactor walls. The complete set of finite difference equations used is given in an appendix.

A design study of a closed loop test facility for eight-inch hot dirty gas valves is presented. The objective of the facility is to quality valves for use in coal gasifiers, combined cycle plants, and pressurized fluid bed combustors. Outline sketches and estimated costs are presented for the selected design.

This manual is intended to serve several purposes. The first goal is to describe the capabilities and operation of the SMC processor package from an operator or user point of view. Secondly, the manual will describe in some detail the basic hardware elements and how they can be used effectively to implement a step motor control system. Practical information on the use, installation and checkout of the hardware set is presented in the following sections along with programming suggestions. Available related system software is described in this manual for reference and as an aid in understanding the system architecture. Section two presents an overview and operations manual of the SMC processor describing its composition and functional capabilities. Section three contains hardware descriptions in some detail for the LLL-designed hardware used in the SMC processor. Basic theory of operation and important features are explained.

The subject program is primarily an exploratory and demonstration study of the use of silicate glass-based adhesives for bonding silicon-base refractory ceramics (SiC, Si/sub 3/N/sub 4/). The projected application is 1250 to 2050/sup 0/F relaxing joint service in high-performance energy conversion systems. The five program tasks and their current status are as follows. Task 1 - Long-Term Joint Stability. Time-temperature-transformation studies of candidate glass adhesives, out to 2000 hours simulated service exposure, are half complete. Task 2 - Environmental and Service Effects on Joint Reliability. Start up delayed due to late delivery of candidate glass fillers and ceramic specimens. Task 3 - Viscoelastic Damping of Glass Bonded Ceramics. Promising results obtained over approximately the same range of glass viscosity required for joint relaxation function (10/sup 7.5/ to 10/sup 9.5/ poise). Work is 90% complete. Task 4 - Crack Arrest and Crack Diversion by Joints. No work started due to late arrival of materials. Task 5 - Improved Joining and Fabrication Methods. Significant work has been conducted in the area of refractory pre-glazing and the application and bonding of high-density candidate glass fillers (by both hand-artisan and slip-spray techniques). Work is half complete.

These notes present a brief survey of some of the current diagnostic techniques used in magnetic fusion plasma devices. To give an idea of the range of parameters and geometries encountered the parameters of four representative experiments - PLT, TMX, ZT-40 and EBT-I(S) - are given. The central issue of all experiments is to understand the flow of power which can be summarized by two volume integrated equations for the ions and electrons.

Income, ethnicity, education, and occupation are examples of socio-economic factors associated with the occurrence of disease, whether an investigation focuses on an individual or on an aggregation of individuals. In this study, data aggregated to the county level are used to explore two issues - geographic variation and geographic covariation of ten selected causes of death in the United States. The counties of the United States are characterized by 15 socio-economic variables and age-adjusted mortality rates for the ten selected causes of death. The observed variation among the US counties, as measured by the socio-economic variables, is first assessed, then the geographic variation and covariation are described for each cause of death and, finally, the covariation among causes of death is analyzed after adjusting for the influences of the measured sources of county variation.

This report contains background information and investigations regarding the Three Mile Island nuclear power accident near Harrisburg, Pennsylvania. It also shows the President's Commission and overall chronology of Committee responses on one of the largest nuclear power plant accident.

The paper discusses two treaties that are being negotiated: Multilateral Treaty, which bans all nuclear weapon tests and establishes a moratorium on PNEs (Peaceful Nuclear Explosions) for the life of the treaty, and a separate verification agreement, which provides for much more extensive verification measures that does the Multilateral Treaty and to which only the US, UK, and USSR will adhere. On the latter treaty, agreement has been reached that there will be improved seismic stations (NSS) in each country. Discussed are the outstanding general points of agreement or disagreement on NSS; technical characteristics of NSS; and a joint cooperative program for NSS.
