Plans for zero discharge of aqueous waste from ERDA's nuclear weapons plant near Denver are discussed. Two plants - a process waste treatment facility now under construction, and a reverse osmosis desalting plant now under design, will provide total reuse of waste water for boiler feed and cooling tower supply. Seventy million gallons of water per year will be conserved and downstream municipalities will be free of inadvertent pollution hazards.

Recommendations to ERDA of four solar heating and cooling demonstration projects are presented. Recommendations include (1) the Westchester Work Center Building owned by Bell Telephone Company of Pennsylvania, (2) the Scottsdale County Courts Building in Scottsdale, Arizona, (3) Howard Johnson's Inc. Hotel in North Miami, Florida, and (4) a combination warehouse, manufacturing facility offered by Mr. John I. Ladd of Ladd Brothers, Pueblo, Colorado. A conceptual diagram and a fact sheet is included for each proposed demonstration site. The combined estimated cost for the four projects is $334,586. (WHK)

A summary is given of the geologic structure of the test facility in Imperial County. The analysis is based on well records, especially electrical logs. (LBS)

MAFJ is a revision of the MAFCO code which generates magnetic fields (B) resulting from collections of current elements. In addition to the original MAFCO's capabilities, MAFJ follows field lines through a region of interest and calculates integrals of functions along these lines. It can also generate three-dimensional grids of B. MAFJ runs from eight to 15 times faster than MAFCO, depending on the types of current elements chosen. 2 tables.

During 1975, approximately 1.33 x 10/sup 13/ liters of gaseous effluents were monitored for radioactivity by the stack sampling program. A summary of the measured radioactivity was as follows: alpha (assumed source--Pu)--1.45 x 10/sup -3/ Ci and beta--0.418 Ci.

An x-ray photodensitometer provided accurate and precise measurements of linear dimensions on radiograph images. These measurements helped to infer the hidden dimensions of objects radiographed. A goal was to achieve an accuracy of +-25 ..mu..m. The recorded accuracy did not measure up to the precision, which, under favorable conditions, was +-25 ..mu..m. Systematic errors caused the errors in absolute value to be considerably higher in some cases. To satisfy this, auxiliary calibrations were made. Many deterrents to successful measurement arose. These included film grain noise, excessive density range and edge penetration, blurring, interfering structures, and scattered radiation. Film grain noise, in particular, limited the resolution of small details (fine structure) in a radiograph. Because of so many deterrents, the applicability of the measurement method used appears quite limited.

Separate abstracts were prepared for seven sections of this report that discuss diagnostic techniques using radioisotopes as tracers.

SIGHDT is a function subroutine for approximating reaction cross sections for hydrogen isotopes. It is available on the OCTOPUS and Controlled Thermonuclear Research (CTR) networks at Lawrence Livermore Laboratory.

A description of the Salton Sea geothermal reservoir is given and includes approximate fault locations, geology (lithology), temperatures, and estimates of the extent of the reservoir. The reservoir's temperatures and chemical composition are also reviewed. The flow characteristics are discussed after analyses of drillstem tests and extended well tests. The field production, reserves and depletion are estimated, and the effects of fractures on flow and depletion are discussed. The reservoir is believed to be separated into an ''upper'' and ''lower'' portion by a relatively thick and continuous shale layer. The upper reservoir is highly porous, with high permeability and productivity. The lower reservoir is at least twice as large as the upper but has much lower storativity and permeability in the rock matrix. The lower reservoir may be highly fractured, and its temperatures and dissolved solids are greater than those of the upper reservoir. The proven reserves of heat in the upper reservoir are about /sup 1///sub 4/ GW.yr (in the fluid) and /sup 1///sub 3/ GW.yr (in the rock). In the lower reservoir the proven reserves of heat are 5/sup 3///sub 4/ GW.yr (in the fluid) and 17 GW.yr (in the rock). Unproven reserves greatly exceed these numbers. Injection …

Runoff-water samples for the first, third, and fourth quarters of 1975 were analyzed for pesticide residues at LLL and independently by the LFE Environmental Analysis Laboratories. For the compounds analyzed, upper limits to possible contamination were placed conservatively at the low parts-per-billion level. In addition, soil samples were also analyzed. Future work will continue to include quarterly sampling and will be broadened in scope to include quantitative analysis of a larger number of compounds. A study of recovery efficiency is planned. Because of the high backgrounds on soil samples together with the uncertainties introduced by the cleanup procedures, there is little hope of evaluating the distribution of a complex mixture of pesticides among the aqueous and solid phases in a drainage sample. No further sampling of soil from the streambed is therefore contemplated.

The usefulness of the Yerzley mechanical oscillograph in detecting differences among Y3333 cellular silicones was evaluated. Four properties of Y3333 were measured: density, thickness, resilience, and effective dynamic modulus. Test samples came from five lots of standard Y3333 compound and from two lots of experimental Y3333. Tests of the four properties revealed that individual sheets of Y3333 were homogeneous. Since sheets from the same lot differed little in properties, normal process variations had minimal effect on properties. Although lot-to-lot variation of standard Y3333 was statistically significant, the coefficients of variation of 5 percent or less indicated a reasonable consistency among the five lots tested. The two experimental lots of Y3333, made with known material and manufacturing variables, showed a response to the variations but maintained low coefficients of variation. After evaluating the Yerzley instrument, it was decided that it demonstrated its worth for detecting differences among Y3333 cellular silicones.

A status report of microinstability as it applies to 2XIIB and MX theory for mirror machines is presented. It is shown that quasilinear computations reproduce many of the parameters observed in the 2XIIB experiment. In regard to large mirror machines, there are presented detailed calculations of the linear theory of the drift cyclotron loss-cone mode, with inhomogeneous geometry and nonlinear diffusive effects. Further, the stability of a mirror machine to the Alfven ion-cyclotron instability is assessed, and the Baldwin-Callen diffusion is estimated for a spatially varying plasma.

The chemical basis for molten salt extraction separation of americium from plutonium is presented. The extraction factor relationship is used to quantify this liquid-liquid extraction (molten salt-molten metal) unit operation. The amount of salt required for an optimum process is an order of magnitude lower than the amount used previously in the production operation of the process.

This completes the first year of the ERDA funded South Atlantic Bight study and much of the activity involved equipment acquisition and historical data analysis. However, in spite of the lack of equipment, we did run a full scale experiment in Onslow Bay in September 1975 and data acquired forms the principal scientific results for the year. Data reports and publications are attached. The accomplishments, scientific and otherwise, are summarized on the next few pages followed by a more lengthy discussion and appendices.

The High Frequency System is a new mobile, digital diagnostic recording system for use at the Nevada Test Site. Many different kinds of event data will be digitized in real-time by this system, and these data will be recorded and stored for later read-out and transmission to NADCEN. The hardware and software requirements of the High Frequency System are examined, and the parameters of the system are proposed.

The circulating protons in the ISABELLE intersecting storage ring accelerator will collide with the residual gas in the vacuum chamber. The electrons produced will tend to be captured by the potential well of the beam itself and result in a neutralization of the space charge of the beam. A detailed analysis is given of the various mechanisms which can be used to reduce the net degree of beam neutralization. It is concluded that the average neutralization will be about 10/sup -4/ for a residual gas pressure of 3 x 10/sup -11/ torr of hydrogen.

Differential cross sections for incoherent scattering by K-shell electrons were measured, using coincidence techniques, for incident photons having energies of 662 keV, 320 keV, and 145 keV. The spectral distributions of the scattered photons emerging at scattering angles from 20/sup 0/ to about 140/sup 0/ are reported. Target materials were iron, tin, holmium, and gold at 320 keV; tin and gold at 662 keV; and iron and tin at 145 keV. A typical energy spectrum consists of a scattered peak that is much narrower than would be expected from the bound state electron motion. The peak also, typically, reaches a broad maximum width for scattering angles between 45/sup 0/ and 60/sup 0/. Rather than monotonically increasing with atomic number the peak width reaches a broad maximum, generally, between Z = 50 and Z = 67, and then decreases with increasing atomic number. No Compton defect appears in any of the peaks to within +- 20 keV. A discussion of the expected magnitude of the Compton defect is included. The peak is superimposed on a continuum that diverges at the low end of the scattered photon spectrum for the following cases: gold, holmium, and tin targets for 320-keV incident photons; gold …

The number of beams required for optimum power transfer from a given power source to the surface of a pellet is derived. The result is valid for linear optical systems, hence, for pellet fusion by laser or high energy ion beams. The optimum number of beams turns out to be inconceivably large for any practical system. Practical pellet fusion by lasers or high energy heavy ion beams must thus compromise physical principles in favor of reduced cost and optical complexity.

Over the course of OBIS II, 3-14 September, two intrusion cores were observed. One was apparently trapped nearshore over much of the study period, but as time went on, it either dissipated, moved too far shoreward or moved too far laterally along the shelf to be detected by the existing observational grid. The other (later) intrusion was first detected on 5-7 September and was observed to be moving into the Bay from the southeast over the remainder of the study period. Plots of the horizontal temperature and salinity distribution were suggestive of these phenomenon by means of the higher salinity-lower temperature relationship. However, the real confirmation rests in the vertical distributions of sigma-t and chlorophyll presented in conjunction with the Bio and Hydrogrids, and the T--S plot which reveals slope waters on the shelf. The intruded waters were not of low enough temperature to carry high nutrient concentrations onto the shelf for study. However, the general results of this study tend to confirm the view that our basic grid array and methods are compatible with measurement of the processes we initially set out to study. Analyses of these data relative to the current meter data will allow a nearly complete …

Measurements of the microwave cross section of the ionized channel created by an intense electron beam propagating in a high density gas are reported. Following a brief theoretical treatment, experimental values at normal incidence for back scattered, forward scattered, and 90/sup 0/ scattered cross section of the beam are reported at 24 GHz for air and nitrogen at 500 torr pressure.

Calculation of the resolved shear stresses (rss) that act on various deformation systems in metals and, in particular, the determination of those systems subjected to the highest rss by a given set of multiaxial stresses is of importance in the study of texture development, yielding and plastic flow. This study examines the geometrical influences of any stress state on the deformation modes of zirconium. One slip mode and three twinning modes, comprising twenty-one deformation systems, are considered. Stress factors computed for these systems are shown on a coordinate system that allows specimen orientation, most highly stressed deformation system, and stress factor to be shown without ambiguity. The information in this report allows the determination of the rss that results from any multiaxial stress state; this information also allows the prediction of the deformation modes that might operate for any specimen orientation in that strss state.
