This annual technical progress report, based on the same four divisions used in our original proposal, provides only a brief synopsis of the research carried out dudng the past three years. We have also included a brief description of algorithms and computer programs that have been transferred to the ARM management. Such transfers of knowledge and technique are vital for the success of the ARM program. Various members of our research group participated in two major field programs: the First ISSCP Regional Experiment (FIRE) Cirrus II Experiment held in November 1991, in Kansas, and the Atlantic Stratocumulus Transition Experiment (ASTEX) held in the Azores in June 1992. Although our participation in these campaigns was funded primarily through other agencies, the data collected in these programs were essential for certain components of our research. The graphical user interface programs that were transferred to ARM were a direct outgrowth of these field activities as well. In addition, we collected a variety of data at Penn State using our 94 GHz radar, microwave radiometer, wind profilers, and other instruments. Again these data were acquired to meet the needs of our proposed research.

We have measured the spectra of gamma rays from approximately 14 MeV to the endpoint in the {sup 89}Y({rvec p},{gamma}) reaction with 19.6 MeV polarized protons from the TUNL tandem accelerator. Gamma spectra were measured with a pair of 25.4 cm {times} 25.4 cm anticoincidence shielded NaI detectors at angles of 30, 55, 90, 125, and 150{degrees} with respect to the incident beam. The {gamma}-ray spectra show significant analyzing powers and forward peaking of the angular distributions. These features allow for the discrimination between compound processes which do not exhibit interference between different channels, and direct processes. The observed interference effects indicate that multistep-direct processes are important at {gamma}-ray energies lower than those for which direct-semidirect capture is the dominant mechanism.

This description of work (DOW) details the field activities associated with assessing the vertical extent of groundwater contamination in the uppermost unconfined and confined aquifers beneath the southeastern portion of the 200 West area. The document serves as the test plan for those performing the work. It should be used in conjunction with the Remedial Investigation/Feasibility Study Work Plan for the 200-UP-1 Groundwater Operable Unit, Hanford Site, Richland, Washington (200-UP-1 Operable Unit Workplan) (DOE/RL 1991) for general investigation strategy and with specific procedures. Work scope for the vertical profiling activity is defined in sections 4.2 and 5.1.3 of the 200-UP-1 Operable Unit Workplan. The work is one portion of a proposed Limited Field Investigation (LFI) data collection program.

This report documents the technical and time bases used to conclude that the fission product, Sr{sup 89}, should no longer be considered as a contaminant of concern and an analyte in SRS environmental samples. This conclusion is the basis for hard-dollar cost savings suggestions to eliminate its analysis in F/H Areas Seepage Basin monitoring wells and in future soil, sediment and water environmental samples for which the analytical contract is to be awarded prior to October 1, 1993. Environmental Restoration should proactively pursue regulatory approval for the elimination of Sr{sup 89} as an analyte in appropriate environmental samples.

This report describes a new algorithm developed for the Imigration and Naturalization Service (INS) in support of the INSENS project for classifying vehicles and pedestrians using seismic data. This algorithm is less sensitive to nuisance alarms due to environmental events than the previous algorithm. Furthermore, the algorithm is simple enough that it can be implemented in the 8-bit microprocessor used in the INSENS system.

This test summary describes the objectives, methodology, and results of a physical separations soil-washing system setup and shakedown test using uncontaminated soil. The test is being conducted in preparation for a treatability test to be conducted in the North Pond of the 300-FF-1 Operable Unit. It will be used to assess the feasibility of using a physical separations process to reduce the volume of contaminated soils in the 300-FF-1 Operable Unit. The test is described in DOE-RL (1993). The setup test was conducted at an uncontrolled area located approximately 3.2 km northwest of the 300-FF-1 Operable Unit. The material processed was free of contamination. The physical separation equipment to be used in the test was transferred to the US Department of Energy (DOE) by the US Environmental Protection Agency (EPA) Risk Reduction Engineering Laboratory. On May 13, 1993, soil-washing equipment was moved to the cold test location. Design assistance and recommendation for operation was provided by the EPA.

This project is a major step in the Department of Energy`s program to show that ultra-clean coal-water slurry fuel (CWF) can be produced from selected coals and that this premium fuel will be a cost-effective replacement for oil and natural gas now fueling some of the industrial and utility boilers in the United States. The replacement of oil and gas with CWF can only be realized if retrofit costs are kept to a minimum and retrofit boiler emissions meet national goals for clean air. These concerns establish the specifications for maximum ash and sulfur levels and combustion properties of the CWF. This cost-share contract is a 48-month program which started on September 30, 1992. This report discusses the technical progress made during the quarter from April 1 to June 30, 1993. The project has three major objectives: (1) the primary objective is to develop the design base for prototype commercial advanced fine coal cleaning facilities capable of producing ultra-clean coals suitable for conversion to coal-water slurry fuel for premium fuel applications. The fine coal cleaning technologies are advanced column flotation and selective agglomeration. (2) a secondary objective is to develop the design base for near-term application of these advanced fine …
