Application of mineralogical methods to assess the thermal stabilities of geothermal reservoirs
Estimates of temperatures, past and present, in geothermal reservoirs can be made by using now standard mineralogical techniques, including fluid inclusion geothermometry, vitrinite reflectance, calc-silicate and clay occurrence, the extent of clay interlayering, and measuring clay crystallinity. Recent studies of clays in 60 drillcores from 6 wells at Wairakei, for example, show an inverse relationship between reservoir temperatures and crystallinities from 90° to 225°C (195 to 435°F) (Kübler Indices: 1.40 to 0.44 <FONT FACE="Symbol">D</FONT>°2<FONT FACE="Symbol">q</FONT>). Fluid inclusion geothermometry results require careful interpretation but the method need not be calibrated with respect to the reservoir, as do other geothermometric methods.

An approach for geochemical assessment of Chipilapa geothermal field
It presents a systematic methodology to evaluate the reservoir characteristics of Chipilapa- Ahuachapan geothermal field through the highly diluted natural manifestations (springs and domestic wells) in its surroundings. The manifestations are classified in three main groups according to their mechanism of formation: high salinity water (HSW), medium salinity water (MSW), and Sulfated Water (SW). The reservoir temperature at Chipilapa geothermal field is around 220°C which is estimated with application of various chemical geothermometers. The isotopic studies indicate that the heating of local meteoric water with the separated steam of deep reservoir fluids is a dominating process in the formation of springs and domestic wells fluids. The process of formation of primary and secondary vapor explains the isotopic composition of fumaroles.

Audit of Department of Energy`s warehouse space
The Department of Energy (Department) and its contractors use warehouses for the storage of various items including furniture, equipment, and office supplies. As of August 23, 1996, the Department had about 3.5 million square feet of total warehouse space of which about 493,000 square feet was leased from outside sources. The annual cost of these leases was over $2.5 million. The purpose of the audit was to assess the efficiency of the Department`s use of warehouse space. Specifically, our objective was to determine whether the Department was minimizing the need for warehouse space for the storage of furniture, equipment, and office supplies.

BIOMASS REBURNING - MODELING/ENGINEERING STUDIES
This project is designed to develop engineering and modeling tools for a family of NO<sub>x</sub> control technologies utilizing biomass as a reburning fuel. The fifth reporting period (October 1 � December 31) included modeling of the Advanced Reburning (AR) process while firing biomass. Modeling of Advanced Biomass Reburning included AR-Lean, AR-Rich, and reburning + SNCR. Fuels under investigation were furniture pellets and willow wood. Modeling shows that reburning efficiency increases when N-agent is injected into reburning or OFA zones, or co-injected with OFA. The kinetic model trends qualitatively agree with experimental data for a wide range of initial conditions and thus can be used for process optimization. No patentable subject matter is disclosed in the report.

BIOSPHERE MODELING AT YUCCA MOUNTAIN, NEVADA
The objectives of the biosphere modeling efforts are to assess how radionuclides potentially released from the proposed repository could be transported through a variety of environmental media. The study of these transport mechanisms, referred to as pathways, is critical in calculating the potential radiation dose to man. Since most of the existing and pending regulations applicable to the Project are radiation dose based standards, the biosphere modeling effort will provide crucial technical input to support the Viability Assessment (VA), the Working Draft of License Application (WDLA), and the Environmental Impact Statement (EIS). In 1982, the Nuclear Waste Policy Act (NWPA) was enacted into law. This federal law, which was amended in 1987, addresses the national issue of geologic disposal of high-level nuclear waste generated by commercial nuclear power plants, as well as defense programs during the past few decades. As required by the law, the Department of Energy (DOE) is conducting a site characterization project at Yucca Mountain, Nevada, approximately 100 miles northwest of Las Vegas, Nevada, to determine if the site is suitable for the nation's first high-level nuclear waste repository.
