A soil-gas survey was conducted near the 382 Pump House in the 300 Area of the Hanford Site. The objective of the soil-gas survey was to characterize the extent of petroleum product contamination in the soil beneath the 382-1 underground gasoline storage tank excavation. The tank was discovered to have leaked when it was removed in September 1992. The results of this soil-gas survey indicate petroleum products released from the 382-1 tank are probably contained in a localized region of soil directly beneath the tank excavation site. The soil-gas data combined with earlier tests of groundwater from a nearby downgradient monitoring well suggest the spilled petroleum hydrocarbons have not penetrated the soil profile to the water table.

Worldwide efforts in fusion energy research are designed to develop fusion power as a safe, environmentally sound, and economically competitive source of energy. The International Thermonuclear Experimental Reactor (ITER) project is a worldwide effort to demonstrate the scientific and technological feasibility of fusion power. The European Community, Japan, the Russian Federation, and the United States are collaborating on ITER, with each of the four parties expected to equally share costs and benefits. Shared costs for the current engineering design phase of the project are estimated at $1 billion in 1989 dollars, excluding certain management and support costs to be absorbed by each partner, with an early estimate of $6 billion, also in 1989 dollars, for construction of the reactor. Engineering design formally began in July 1992, and this phase is in its formative stages. The US had already spent about $100 million since 1987 on ITER conceptual design activities and other preparatory activities in advance of the engineering design phase. Because of its cost significance, the importance of ITER to the US fusion energy program, and the project`s unique aspects which may provide a framework for future international endeavors, we initiated an audit of the ITER project. The purpose of …

This description of work (DOW) details the field activities associated with the vadose zone drilling and soil sampling in the 200-UP-2 Operable Unit (Task 2, 3, and 5) and will serve as a field guide for those performing the work. It will be used in conjunction with the 200-UP-2 RCRA Facility Investigation/Corrective Measures Study (DOE-RL 1993a,[LFI]) and Site Characterization Manual (WHC 1988a). Vadose zone borings are being constructed to characterize the vertical and horizontal extent of contaminants in sediments within and beneath the cribs. The locations for the proposed borings are presented in Figure 1. The contaminants of concern for the project are presented in Table 1.

We apply dual-band infrared (DBIR) imaging as a dynamic thermal tomography tool for wide area inspection of a Boeing 737 aircraft, and several Boeing KC-135 aircraft panels. Our analyses are discussed in this report. After flash-heating the aircraft skin, we record synchronized DBIR images every 40 ms, from onset to 8 seconds after the heat flash. We analyze selective DBIR image ratios which enhance surface temperature contrast and remove surface-emissivity clutter (from dirt, dents, tape, markings, ink, sealants, uneven paint, paint stripper, exposed metal and roughness variations). The Boeing 737 and KC-135 aircraft fuselage panels have varying percent thickness losses from corrosion. We established the correlation of percent thickness loss with surface temperature rise (above ambient) for a partially corroded F-18 wing box structure and several aluminum reference panels. Based on this correlation, lap splice temperatures rise 1{degrees}C per 24 {plus_minus} 5 % material loss at 0.4 s after the heat flash. We show tables, charts and temperature maps of typical lap splice material losses for the riveted (and bonded) Boeing 737, and the riveted (but unbonded) Boeing KC-135. We map the fuselage composite thermal inertia, based on the (inverse) slope of the surface temperature versus inverse square root of …

During this reporting period, the solubilities of nitrogen in n-decane and in n-eicosane were measured at temperatures form 323.2 to 423.2 K (122.0 to 302.0{degrees}F) and pressures to 17.2 MPa (2,49 psia). These data are described with root-mean-square (RMS) errors typically less than 0.001 in mole fraction by the Soave-Redlich-Kwong and Peng-Robinson equations of state when a single interaction parameter, C{sub ij}, is used for each isotherm.

The electrical discharge techniques, called non-thermal, utilize high voltage breakdown of gases using short pulses of one to a few hundred nanoseconds. These short pulses between metal electrodes generate energetic electrons without appreciable thermal heating of the gas. The energetic electrons collide with gas molecules to form radicals. The radicals then react with pollutants to form harmless compounds. Our experimental device uses a wire in a pipe geometry. The wire is driven by a 40 kilovolt pulse 100 nanoseconds long. Gas is circulated in a loop through the pipe geometry in a closed system. This system permits the introduction of various gas combinations prior to testing. The recirculated gas can be heated to determine the effect on the electrical discharge, and chemical reactions. The efficiency of pollutant removal is the key to applications. We have been able to significantly improve the efficiency of NO removal by the addition of hydrocarbons. Nitric oxide has been removed with an energy cost of 15 ev per NO molecule. We believe the hydrocarbon additive serves by recycling the hydroxyl radicals during the oxidation and reduction of NO. The implementation of this process will depend largely on how much additives, electrical power consumption, and final …

This document is a progress report to the USDOE Atmospheric Radiation and Measurement Program (ARM). The overall project goal is to relate subgrid-cumulus-cloud formation, coverage, and population characteristics to statistical properties of surface-layer air, which in turn are modulated by heterogeneous land-usage within GCM-grid-box-size regions. The motivation is to improve the understanding and prediction of climate change by more accurately describing radiative and cloud processes.

The safety of the GEM Detector Magnet is analyzed using a computational model to determine current sharing between the cabled conductor and the external aluminum stabilizer. The model includes inductive and transverse conductive effects due to the geometries of the coil and the conductor. A conservative analysis indicates a peak conductor hotspot temperature of {approximately} 50 K at two seconds after the initiation of quench. After this time, additional heating is limited because most of the current in the normal zone region is carried by the aluminum stabilizer and an external protection circuit should have begun to diminish the total current. The analysis shows that conductor safety requires adequate transverse conductivity between the cable and the aluminum stabilizer. The calculated transverse conductance of the GEM conductor, 1 {times} 10{sup 7} mho/m, is at least 100 times greater than the minimum value necessary to limit the hotspot temperature to {approximately} 50 K after two seconds. This report describes the results of calculations based on a realistic assumption of GEM conductor performance during a quench.

The status of the pore water and sediment core analysis of the surface sediments that overlie a major gas-hydrate field on the Carolina Continental Rise and Blake Ridge is reported here. Funding from NIGEC`s southern regional center provided support for a cruise of the RV Cape Hatteras in September 1992 (CH-11-92) on which 20 piston cores were taken. However, over the last 18 months we have had the opportunity to collect an additional 35 piston cores in this region, in part through the assistance of another DOE funded project that is being run by the USGS. At this date, we have pore water data from 55 piston cores which gives us both a regional and a site-specific insight into the processes in this region. It is our intention to combine the results of all these cores to arrive at a unified understanding of the processes acting on the continental margin which influence gas-hydrate formation and distribution. Some of the highlights of this work and some of accomplishments of this project to-date are outlined.

This is the final report for the DOE project ``Silicon Drift-Chamber studies for Possible use at RHIC`` carried out at the University of Pittsburgh by T. J. Humanic. This study was carried out during the period March 1989--April 1993 under DOE Grant No. DE-FG02-89ER40503. The termination of this grant was caused by the movement of the principal investigator from the University of Pittsburgh to Ohio State University, where this work is continuing under a different grant. During this period we investigated various aspects of silicon drift chambers including two-track resolution, effects of external magnetic fields and different detector designs.
