In August of 1990 the Savannah River Site Photography Group began testing on a different type of silver recovery system. This paper describes the baseline study and the different phases of installation and testing of the system.

The purpose of this audit was to determine whether the Department of Energy's (Department) management of its contract with Ross Aviation, Inc. (Ross) provided reasonable assurance that the inventory of aircraft major spare parts at Ross was economical and efficient. The audit disclosed that approximately $447,000 (acquisition and interest carrying costs) of low-use major spare parts was excessive. Internal control deficiencies which fostered the excessive inventory included: (1) Ross had set stock levels without considering such factors as consumption or projected needs; and (2) the Department had not reviewed inventory quantities when appraising Ross' property management. The Albuquerque Operations Office (AL) agreed to take the corrective actions recommended in the report.

This publication presents current data on production, consumption, stocks, imports, exports, and prices of the principal energy commodities in the United States.

This memorandum discusses five key issues that initial interviews have brought into focus: The preoccupation of the public with nuclear waste disposal, the credibility of public opinion polls addressing nuclear power, the unlikelihood of dramatic change in opinion by nuclear critics, difficulties in communicating technical concepts, and the problem of focussing narrowly or broadly on policy issues.

As scintillating plate calorimetry is a viable option for the SDC detector, it is imperative that the phase space of passive and active materials be explored in a systematic fashion. To this end, we have examined several different configurations of passive and active materials as a function of incident energy, to see what the resolution and e/h characteristics are of each of these configurations. These studies have been carried out using the CALOR89 Monte Carlo simulation package. 3 figs., 5 tabs.

We have developed a system of quantitative radiography in order to produce quantitative images displaying homogeneity of parts. The materials that we characterize are synthetic composites and may contain important subtle density variations not discernible by examining a raw film x-radiograph. In order to quantitatively interpret film radiographs, it is necessary to digitize, interpret, and display the images. Our integrated system of quantitative radiography displays accurate, high-resolution pseudo-color images in units of density. We characterize approximately 10,000 parts per year in hundreds of different configurations and compositions with this system. This report discusses: the method; film processor monitoring and control; verifying film and processor performance; and correction of scatter effects.

The accomplishments of the work done under DOE sponsorship are summarized in the list of publications at the end of this narrative. Here we give a brief description of the nature and the significance of the accomplishments. The activity can be roughly subdivided into three parts: studies of surface alloys, studies of epitaxial ultra-thin films, and studies of electron band structure of metals. The list reflects the developments of particular areas of research and the phasing out of others as this was suggested by the interest in, and the success of, specific experimental projects.

A multiphase experimental program to assess and understand waste glass behavior under a wide range of conditions has been in progress at the Savannah River Laboratory (SRL) for over a decade. An important part of this experimental effort is to assess the effects of repository relevant conditions on performance of SRS waste glass, in both controlled laboratory tests, as well as in actual field experiments. In laboratory test, SRS waste glass, simulated and in many cases also fully radioactive, has been tested in environments of salt, basalt, shale, granite, clay and tuff. In field experiments, there are four joint international programs being conducted in four different countries, involving burial of SRS simulated waste glass in granite, limestone, clay and salt geologies. This report discusses the SRS waste glass studies in limestone at Ballidon, UK..

This is an evaluation of the Crude Oil Policy Model (COPM) and the assumptions driving the estimates of future crude oil production and abandonments attributable to an accelerated federal oil R&D program which were cited in the National Energy Strategy. This evaluation focuses on the logic and inputs to the model itself, and their impact on the NES estimates. A plan for making the recommended enhancements is also discussed. A parallel effort is also now in progress to make a number of model enhancements that will facilitate the analysis of RCRA impacts. This effort is scheduled to be completed for the Office of Planning and Environment in mid-August. A description of these enhancements is also included in our plan for correcting and enhancing the COPM.

The design of the EC carriage is based on the design of the CC carriage documented in D-0 Engineering Note 3740.215-EN-14. The non-symmetric weight distribution of the EC cryostat results in uneven loading of the arms of the EC carriage. The design load on each rear arm is 220,000 lb, while each front arm supports 40,000 lb. (The CC carriage design load was 200,000 lb on all four arms.) ANSYS finite element models were made representing various combinations of plate thicknesses in an attempt to balance the deflections of the arms. In the final design a 3/4-inch curved top plate is used with an additional 1.75-inch thick 'doubler plate' incorporated into the rear arms. The bottom flanges are 2-inch and 3/4-inch for the rear and front arms, respectively. Web plates are 3/4-inch for all arms. The carriage bottom plate is 2-inch thick, and other details are similar to the CC design.

During the accelerator studies period of 12/90-1/91 much study time was dedicated to improving the E760 deceleration ramps. 4 general goals were in mind: (1) Reduce the relative orbit deviations from the nominal reference orbit as much as possible. This reduces the potential error in the orbit length calculation - which is the primary source of error in the beam energy calculation. (2) Maximize the transverse apertures. This minimizes beam loss during deceleration and during accidental beam blow-ups. (3) Measure and correct lattice parameters. Knowledge of {gamma}{sub T}, {eta}, Q{sub h}, Q{sub v}, and the dispersion in the straight sections allows for a more accurate energy calculation and reliable SYNCH calculations. (4) Minimize the coupling. This allows one to discern between horizontal and vertical tunes.

Ongoing studies by the National Aeronautics and Space Administration (NASA) for the robotic exploration of Mars contemplate a network of at least twenty small and relatively inexpensive landers distributed over both low and high latitudes of the Martian globe. They are intended to explore the structural, mineralogical, and chemical characteristics of the Martian soil, search for possible subsurface trapped ice, and collect long-term seismological and meteorological data over a period of ten years. They can also serve as precursors for later unmanned and manned Mars missions.; The collected data will be transmitted periodically, either directly to Earth or indirectly via an orbiting relay. The choice of transmission will determine the required power, which is currently expected to be between 2 and 12 watts(e) per lander. This could be supplied either by solar arrays or by Radioisotope Thermoelectric Generators (RTGs). Solar-powered landers could only be used for low Martian latitudes, but RTG-powered landers can be used for both low and high latitudes. Moreover, RTGs are less affected by Martian sandstorms and can be modified to resist high-G-load impacts. High impact resistance is a critical goal. It is desired by the mission designers, to minimize the mass and complexity of the system …

Pressure vessels must be protected against overpressure scenarios. A scenario of particular concern is that from a high pressure LN2 pump, now standard on LN2 delivery trailers. A safety mechanism must be in place to prevent the overfilling, and subsequent overpressure from occurring because these pumps have a higher mass flow output than reasonably sized relief valves provide. The original solution to the problem was to close a valve on the fill line when a certain liquid level in the dewar is reached. The valve remains closed until the level drops below that threshold. The trigger level was about 13,000 gallons for the 20,000 gallon capacity dewar. The solution was in place from 1989 until present, 2004.

In both Japan and in the United States, industrial associations play an important role in enhancing government understanding and interaction with industries and in easing cooperative efforts among firms. This report examines the role of industrial associations and related organizations in high-technology policymaking and in accelerating technological development.

Trade relations between the United States and Japan in the 1980s were marked by U.S. efforts to pressure Japan to absorb increasingly greater amounts of U.S. exports. The United States sought to improve its steadily worsening bilateral trade deficit with Japan by negotiating to lower barriers to U.S. exports through the General Agreement on Tariffs and Trade, the Market Oriented, Sector Selective Talks, the Super 301 process, the Structural Impediments Initiative, and other bilateral fora. The United States succeeded in having Japan take some market-opening measures, and despite fluctuations, U.S. exports to Japan of most of the products which were the subject of negotiations by the two countries between 1985 and 1990 have increased.

In September of 1987, the principals of what is now Hi-Z TECHNOLOGY, INC. applied to the National Bureau of Standards (now National Institute of Standards and Technology, NIST) under the Energy Related Inventions Program. The invention was entitled ``Thermoelectric Generator for Diesel Engines.`` The National Institute of Standards and Technology evaluated the invention and on January 12, 1989 forwarded Recommendation Number 455 to the Department of Energy (DOE). This recommendation informed the DOE that the invention had been selected for recommendation by the NIST for possible funding by the DOE. Following the recommendation of the NIST, the DOE contacted Hi-Z to work out a development program for the generator. A contract for a grant to design, fabricate, and test a Proof-of-Principle exhaust powered thermoelectric generator for Diesel engines was signed October 19, 1989. Hi-Z provided the thermoelectric modules used in the generator as their contribution to the project. The purpose of this Grant Program was to design, build, and test a small-scale, Proof-of-Principle thermoelectric generator for a Diesel engine. 15 figs., 1 tab.
