Airborne temperature surveys were used to depict the small surface temperature differences related to heat flow anomalies. Zones with conductive heat flow differences of 45 +- 16 ..mu..cal/cm/sup 2/(s) had predawn surface temperature differences of 1.4 +- 0.3/sup 0/C. Airborne temperature surveys were coordinated with field temperature surveys at Long Valley, California, the site of a known geothermal resource area. The airborne temperature surveys recorded redundant, predawn temperatures at two wavelengths and at two elevations. Overall temperature corrections were determined by calibrating dry soil surface temperatures with thermistor probes. The probes measured air and soil temperatures within 2 cm of the surface, every twenty minutes, during the survey overflights.

Infrared radiometers have been used to make time-resolved emission measurements of shocked explosives. Instruments of moderate time resolution were used to estimate temperatures in shocked but not detonated explosives. The heterogeneity of the shock-induced heating was discovered in pressed explosives by two-band techniques, and the time-resolved emittance or extent of hot spot coverage indicated a great dependence on shock pressures. Temperatures in moderately shocked organic liquids were also measured. Faster response radiometers with 5 ns rise times based on InSb and HgCdTe photovoltaic detectors were constructed and tested. Preliminary data on reactive shocks and detonations reveal a resolution of the heating in the shock wave and the following reaction.

The method of two-time expansions is extended to include the effects of the outer, non-adiabatic layers in stellar pulsation. The evolution of pulsating stellar models can be examined, including the approach to limit cycle behavior. The method is demonstrated by a calculation of the eigenvectors for a ..beta.. Cepheid model. It is argued that the method is promising as a practical tool for treating the approach to limiting oscillations, as well as resonant and multimode behavior.

The present report begins with a brief overview of nuclear shapes and level structures at high-spin values. The new spectroscopy associated with angular-momentum alignments is described, and some of the exciting possibilities of this spectroscopy are explored. Nuclear moments of inertia are discussed and a somewhat different one is defined, together with a method for measuring it and some early results. Finally a few comments on the future prospects for high-spin physics are offered.

The three current bubble-chamber experiments on charmed-particle lifetimes are compared. Their most recently released results are discussed.

In this paper we describe the calibration of a photometer designed to measure the cosmic microwave background radiation in the frequency range from 3 to 10 cm/sup -1/. The general problem of absolute calibration for such measurements is discussed. The design of a new experiment which is different in most important respects from the Woody-Richards experimentis then presented. A mathematical model of the calibration procedure is developed which includes an analysis of ways in which the procedure can fail to give accurate results.

General Atomic Company (GA) is conducting pilot-plant-scale tests that simulate the treatment of radioactive and other noxious volatile and gaseous constituents of off-gas streams from nuclear reprocessing plants. This paper reports the results of engineering-scale tests performed on the CO/sub 2//krypton separation and radon holdup/decay subsystems of the GA integrated off-gas treatment system. Separation of CO/sub 2/ from krypton-containing gas streams is necessary to facilitate subsequent waste processing and krypton storage. Molecular sieve 5A achieved this separation in dissolver off-gas streams containing relatively low krypton and CO/sub 2/ concentrations and in krypton-rich product streams from processes such as the krypton absorption in liquid carbon dioxide (KALC) process. The CO/sub 2//krypton separation unit is a 30.5-cm-diameter x 1.8-m-long column containing molecular sieve 5A. The loading capacity for CO/sub 2/ was determined for gas mixtures containing 250 ppM to 2.2% CO/sub 2/ and 170 to 750 ppM krypton in either N/sub 2/ or air. Gas streams rich in CO/sub 2/ were diluted with N/sub 2/ to reduce the temperature rise from the heat of adsorption, which would otherwise affect loading capacity. The effluent CO/sub 2/ concentration prior to breakthrough was less than 10 ppM, and the adsorption capacity for krypton was negligible. …

Electron-capture, ionization, and recoil-ion-production cross sections are measured and calculated for fast highly charged projectiles in hydrogen and rare-gas targets. Recoil-ion-production cross sections are found to be large; the low energy and high charge states of the recoil ions make them useful for subsequent collision studies.

The common approach to leakage area measurements in residential housing through pressurization of an entire structure with a blower door. However, this technique does not provide quantitative measurements of the leakiness of individual building components. By pressurizing individual components, it is possible to determine the distribution of leakage within a structure. The studies described in this paper involved measurement of the leakage areas of fireplaces, bathroom and kitchen exhaust vents, electrical outlets and leakage in the ducts of forced air distribution systems. Component leakage measurements were made in a total of thirty-four houses in Atlanta, Georgia, Reno, Nevada and the San Francisco Bay area. Damperless fireplaces and ductwork were found to be the most significant sources of leakage in the western houses. In the Atlanta houses, where cooling loads dominate, the significant leakage area was in the ductwork of the distribution system for central air conditioning that passes through the unconditioned space in the attic and crawlspace.

The problems and potentials for using daylighting to provide illumination in building interiors are reviewed. It describes some of the design tools now or soon to be available for incorporating daylighting into the building design process. It also describes state-of-the-art methods for analyzing the impacts daylighting can have on selection of lighting controls, lighting energy consumption, heating and cooling loads, and peak power demand.

Double mode pulsation is a very pervasive phenomenon in stars all over the Hertzsprung-Russell diagram. In order of increasing radius, examples are: ZZ Ceti stars, the sun, the delta Scuti stars, RR Lyrae variables, the ..beta.. Cephei variables and those related to them, Cepheids, and maybe even the Mira stars. These many modes have been interpreted as both radial and nonradial modes, but in many cases the actual mode has not been clearly identified. Yellow giants seem to be the most simple pulsators with a large majority of the RR Lyrae variables and Cepheids showing only one pulsation period. We limit this review to those very few cases for classical Cepheids and RR Lyrae variables which display two modes. For these we know many facts about these stars, but the actual cause of the pulsation in two modes simultaneously remains unknown.

Several analytical and numerical studies that address injection and thermal breakthrough in fractured geothermal reservoirs are described. The results show that excellent thermal sweeps can be achieved in fractured reservoirs, and that premature cold water breakthrough can be avoided if the injection wells are appropriately located.

Data relative to aquifer locations, temperature, and water quality for Pleistocene aquifers has been collected and preliminary interpretations of this data are presented here.

The Fermi-Teller theory was originally used to predict the stopping, by ionization losses, of slow charged particles in materials. The theory is based on a calculation of the energy cost to a uniform Fermi sea. However, the Fermi velocity cancels out in the derivation, so the calculated results also apply to a Thomas-Fermi atom, in which each volume element is considered to be a Fermi sea filled to the top of the potential well with atomic electrons. An outline is presented of the modifications required to make the Fermi-Teller theory valid for a slow monopole traversing an insulator using the Thomas-Fermi model of the atom. (GHT)

The paper presents the results of an experimental investigation on the formation mechanism and physical characterization of simulated nuclear aerosols that could likely be released during an HTGR core heat-up accident. Experiments were carried out in a high-temperature flow system consisting essentially of an inductively heated release source, a vapor deposition tube, and a filter assembly for collecting particulate matter. Simulated fission products Sr and Ba as oxides are separately impregnated in H451 graphite wafers and released at elevated temperatures into a dry helium flow. In the presence of graphite, the oxides are quantitatively reduced to metals, which subsequently vaporize at temperatures much lower than required for the oxides alone to vaporize in the absence of graphite. A substantial fraction of the released material is associated with particulate matter, which is collected on filters located downstream at ambient temperature. The release and transport of simulated fission product Ag as metal are also investigated.

Fusion research has matured during the last decade and significant insight into the future program needs has emerged. While some will properly note that the crystal ball is cloudy, it is equally important to note that the shape and outline of our course is discernable. In this short summary paper, I will draw upon the National Mirror Program Plan for mirror projects and on available design studies of these projects to put the specific needs of the mirror program in perspective.

Separate abstracts were prepared for the seventeen papers in this proceedings.

The status of ongoing structural materials programs being conducted in the US to support development and deployment of the high-temperature gas-cooled reactor (HTGR) is described. While the total US program includes work in support of all variants of this reactor system, the emphasis of this paper is on the work aimed at support of the steam cycle/cogeneration (SC/C) version of the HTGR. Work described includes activities to develop design and performance prediction data on metals, ceramics, and graphite.

The soft x-ray streak camera uses the RCA C73435 streak tube body fitted with a removable x-ray cathode. The front of the streak tube is exposed to the vacuum of an experimental chamber, which is not entirely under the control of a streak camera operator. Occasionally, the vacuum becomes poor enough to cause corona and arcing from the cathode to the chamber wall. The corona problem is more difficult because the dimensions of the x-ray camera body are smaller than for the optical camera body. Therefore, we investigated the effects on camera performance of decreasing the accelerating voltage at the cathode from the customary 17 kV. Several operating points were evaluated and 12 kV cathode-to-anode with 5 kV cathode-to-grid were selected for more detailed investigation. Transverse spatial resolution and dynamic range were found to be essentially the same as at our normal operating point of 17 kV for the cathode and 2500 V on the grid. Magnification, sweep linearity and absolute sensitivity changed as expected. In the course of the investigation, we measured the dynamic range with our CCD readout system. The effect of Coulomb repulsion at the crossover point was also measured and found not to affect dynamic range.

The local structure at individual ion sites in simple and multicomponent glasses is simulated using methods of molecular dynamics. Computer simulations of fluoroberyllate glasses predict a range of ion separations and coordination numbers that increases with increasing complexity of the glass composition. This occurs at both glass forming and glass modifying cation sites. Laser-induced fluorescence line-narrowing techniques provide a unique probe of the local environments of selected subsets of ions and are used to measure site to site variations in the electronic energy levels and transition probabilities of rare earth ions. These and additional results from EXAFS, neutron and x-ray diffraction, and NMR experiments are compared with simulated glass structures.

We present preliminary results for the production of the J/psi resonance in 125 GeV/c antiproton and pi minus-nucleon interactions as determined from an analysis of 9100 antiproton and 28,750 pi minus induced J/psi's. Total cross sections (x/sub f/ > 0) for J/psi production by both particle types are determined and the ratio of sigma/sub anti p//sigma/sub ..pi..//sup -/ is found to be 0.88 +- 0.05. Differential cross sections for J/psi production are given as a function of x/sub F/ and p/sub T/. The ratio of the d sigma/dx/sub F/ cross sections as a function of x/sub F/ is shown.

This paper describes an integrated decision procedure for deciding whether a diversion of SNM has occurred. Two possible types of diversion are considered: a block loss during a single time period and a cumulative trickle loss over several time periods. The methodology used is based on a compound Kalman filter model. Numerical examples illustrate our approach.
