Analysis of well test data---Application of probabilistic models to infer hydraulic properties of fractures. [Contains list of standardized terminology or nomenclatue used in statistical models]

Description: Statistical and probabilistic methods for estimating the probability that a fracture is nonconductive (or equivalently, the conductive-fracture frequency) and the distribution of the transmissivities of conductive fractures from transmissivity measurements made in single-hole injection (well) tests were developed. These methods were applied to a database consisting of over 1,000 measurements made in nearly 25 km of borehole at five sites in Sweden. The depths of the measurements ranged from nea… more

Structure and thermochemical kinetic studies of coal pyrolysis

Description: The overall objectives of this project is an intensive effort on the application of laser to the microscopic structure and thermochemical kinetic studies of coal particles pyrolysis, char combustion and ash transformation at combustion level that fluxes in a laser beam. Research emphasis in FY91 is placed on setup and calibration of the laser pyrolysis system, preparation and mass loss studies of Beulah lignite and subbituminous coals. The task is therefore divided into three subtasks. 4 figs.,… more

Review of contractors' personnel security clearances at the DOE Field Office, Albuquerque

Description: The DOE Field Office, Albuquerque (AL) Personnel Security Operations Division was responsible for ensuring that the need to access classified information was limited to persons with proper security clearance levels. The responsibility included justifying that need as well as designating, granting, and rescinding employees {prime} clearances based on the Department of Energy's (Department) access requirements. The purpose of this audit was to determine if the Department unnecessarily granted Q s… more

Audit of New Mexico gross receipts taxes paid by DOE Field Office, Albuquerque Management and Operating contractors

Description: The purpose of the audit was to assess whether the Department and its M O contractors had established controls to assure that the contractors accurately computed their tax liability and issued certificates when appropriate. The audit objectives were to determine if the Department and its M O contractors (1) incurred unnecessary New Mexico gross receipts tax, and (2) complied with laws and regulations concerning their taxes. This report discusses the findings of the audit. (JL)

Radioactive Effluents in Savannah River. Summary Report for 1990

Description: During 1990, low-level radiometric studies of the Savannah River continued to distinguish between effluent contributions from Plant Vogtle and the Savannah River Site. Measurements of these radioactive effluents are of mutual interest to both institutions, as they can address disturbing trends before they become health and legal concerns. The Environmental Technology Section (ETS) has conducted radiometric studies of Plant Vogtle since late 1986, prior to its startup. The plant has two 1100 MWe… more

Vent Stack Liquid N2 RTD Temperature Sensor

Description: This engineering note documents the installation of two temperature sensing RTD's in the BC's. Previously, the temperature sensing device used in all three cryostats consisted of a FNAL designed liquid sensing probe (see EN-168, and drawing ME-273505). This device was necessary because of the concern that overfilling LN2 into the main vent line during cooldown could create an undesirable back pressure on the relief valves or rupture disks. This could possibly hinder the relieving of argon gas a… more

[RE: The North Texas Institute Report]

Description: A memo from Brent Wilson to Jack Davis and William McCarter in regards to the North Texas Institute Report. Wilson writes that his suggestions he had offered back in December remain the same except he added one new suggestion. Wilson states that in the report Davis and McCarter will find issues that have presented themselves in the relationship between DBAE and other ares of the curriculum. Attached to the memo is The North Texas Institute for Educators on the Visual Arts: An Evaluation for the… more

Laser Initiated Actuator study

Description: The program task was to design and study a laser initiated actuator. The design of the actuator is described, it being comprised of the fiber and body subassemblies. The energy source for all experiments was a Spectra Diode 2200-H2 laser diode. The diode is directly coupled to a 100 micron core, 0.3 numerical aperture fiber optic terminated with an SMA connector. The successful testing results are described and recommendations are made.

Design of a high activity and selectivity alcohol catalyst

Description: As specified in our original DOE grant proposal, the objective of this research is to design a new alumina-supported bimetallic catalyst for the selective hydrogenation of carbon monoxide to produce methanol and higher alcohols. A key feature of our research program is our intention to rationally design this catalyst based upon fundamental information about the structure, composition and reactivity of preliminary catalysts synthesized throughout the course of this work. During our first year, w… more

Treatment Technologies at Superfund Sites

Description: The Comprehensive Environmental Response, Compensation. and Liability Act of 1980 (CERCLA), commonly known as Superfund, authorizes the Federal Government, through the Environmental Protection Agency (EPA), to clean up hazardous waste sites. There are currently about 1,200 sites on Superfund's National Priorities List, with remedial costs expected to be around $40 billion.

Modernization of Ohio's coal reserves, Phase 1

Description: The objectives of this project were to determine state-level totals of the estimated economic resource, minable reserve base, and recoverable coal in Ohio, allocated to specified ranges of sulfur and heat content. In addition, resources and reserves were to be categorized by mining methods (surface and underground). Land use and environmental restrictions, needed to determine remaining minable reserves, were to be delineated and percentages of restricted coal calculated. In context of a Phase 1… more
