Appendix A is a catalog of the bituminous coal in 29 states of the contiguous United States which contain identified bituminous coal resources.

The following conclusions were drawn from the study: (1) The US will continue to require new sources of energy fuels and substitutes for petrochemical feedstocks into the foreseeable future. Most of this requirement will be met using coal. However, the cost of mining, transporting, cleaning, and preparing coal, disposing of ash or slag and scrubbing stack gases continues to rise; particularly, in the Eastern US where the need is greatest. UCG avoids these pitfalls and, as such, should be considered a viable alternative to the mining of deeper coals. (2) Of the two possible product gases LBG and MBG, MBG is the most versatile. (3) The most logical use for UCG product in the Eastern US is to generate power on-site using a combined-cycle or co-generation system. Either low or medium Btu gas (LBG or MBG) can be used. (4) UCG should be an option whenever surface gasification is considered; particularly, in areas where deeper, higher sulfur coal is located. (5) There are environmental and social benefits to use of UCG over surface gasification in the Eastern US. (6) A site could be chosen almost anywhere in the Illinois and Ohio area where amenable UCG coal has been determined due …

In earlier work a model of fluorescent and Raman scattering by active molecules represented as classical electric dipoles embedded in small particles was developed. The intensity and angular distribution of the inelastically scattered radiation was shown to depend on the geometric and optical properties of the particle. The model was originally developed for particles having spherical shape and later extended to concentric spheres, cylinders, and prolate spheroids. The active molecules were originally assumed to be isotropically polarizable. The model has been recently extended to certain types of anisotropically polarizable molecules. The model had also been applied to particles having internal structure.

CsAlSi/sub 5/O/sub 12/ exhibits more acid resistance than pollucite (CsAlSi/sub 2/O/sub 6/). At pH values of 1.02 and 1.40, the extraction of Cs from CsAlSi/sub 5/O/sub 12/ at 25/sup 0/C was approximately proportional to the square root of leach time. The Cs extraction at 25/sup 0/C varied as (H/sup +/)/sup 0/ /sup 36/ over the pH range of 1 to 6. Also, the Cs extraction in various brines at 300/sup 0/C/30 MPa was comparable with that for pollucite. CsAlSi/sub 5/O/sub 12/ can be crystallized at about 1000/sup 0/C from calcines if a small amount of CaO is present, but in the absence of such sintering acids, crystallization temperatures of about 1400/sup 0/C are necessary. Compatibility data were also obtained with respect to several other phases with which CsAlSi/sub 5/O/sub 12/ might be expected to coexist in tailored ceramics designed for high-level defense waste.

A laboratory study was made of the effects of a massive dose of {gamma} irradiation upon the mechanical properties of Climax stock quartz monzonite. Twenty-nine cylinders of rocks were tested using the Brazilian method and 26 strain gauged cylinders were tested to failure in uniaxial compression. One-half the cylinders in each group were subjected to a {gamma} ray dose of 13.2 MGy (1.32 x 10{sup 9} rads), or six times the maximum five-year dose to rock at the Spent Fuel Test-Climax, Nevada Test Site. The irradiation treatment lowered the ultimate compressional strength and lowered Young`s modulus under uniaxial loads greater than 20 MPa. The treatment did not measurable affect the elastic behavior of the rock in compression, nor did it affect the Brazilian tensile strength. These trends suggest that the {gamma} irradiation lowered the threshold stress at which microfractures begin to form. The irradiation has apparently not directly induced microfracturing in the rock, so a direct degrading effect on thermal and fluid transport properties is not expected.

The backgrund, structure and use of modern forecasting methods for estimating the future development of geothermal energy in the United States are documented. The forecasting instrument may be divided into two sequential submodels. The first predicts the timing and quality of future geothermal resource discoveries from an underlying resource base. This resource base represents an expansion of the widely-publicized USGS Circular 790. The second submodel forecasts the rate and extent of utilization of geothermal resource discoveries. It is based on the joint investment behavior of resource developers and potential users as statistically determined from extensive industry interviews. It is concluded that geothermal resource development, especially for electric power development, will play an increasingly significant role in meeting US energy demands over the next 2 decades. Depending on the extent of R and D achievements in related areas of geosciences and technology, expected geothermal power development will reach between 7700 and 17300 Mwe by the year 2000. This represents between 8 and 18% of the expected electric energy demand (GWh) in western and northwestern states.

We show experimentally that for a staggered scheme on a variable grid the numerical solution of the wave equation exhibits scattering of waves even when the grid varies slowly and the waves are smooth. We also show that this scattering is predicted very well by a modified equation, which thus serves as a backward error analysis.

Most scenarios for geologic disposal of high-level nuclear waste include the eventual intrusion of groundwater into the repository. Reactions in the system and eventual release of the radionuclides, if any, will be controlled by the chemistry of the groundwater, the surrounding rock, the waste form, and any engineered barrier materials that are present, as well as by the temperature and pressure of the system. This report is a compilation and evaluation of the work completed to date on interactions within the waste-form/host-rock/groundwater system at various points in its lifetime. General results from leaching experiments are presented as a basis for comparison. The factors involved in studying the complete system are discussed so that future research may avoid some of the oversights of past research. Although relatively little hard data on prototype waste-form/repository-system interactions exist at this time, the available data and their implications are discussed. Sorption studies and models for predicting radionuclide migration are also presented, again with a study of the factors involved.

An assessment was made of the Energy Data Base (EDB) of the Department of Energy's Technical Information Center (TIC). As the major resource containing access information to the world's energy literature, EDB products and services are used extensively by energy researchers to identify journal articles, technical reports and other items of potential utility in their work. The approach taken to assessing value begins with the measurement of extent of use of the EDB. Apparent value is measured in terms of willingness to pay. Consequential value is measured in terms of effect - for searching, the cost of reading which results; and for reading, the savings which result from the application of the information obtained in reading. Resulting estimates of value reflect value to the searchers, the reader, and the reader's organization or funding source. A survey of the 60,000 scientists and eingineers funded by the DOE shows that annually they read about 7.1 million journal articles and 6.6 million technical reports. A wide range of savings values were reported for one-fourth of all article readings and three-fourths of all report readings. There was an average savings of $590 per reading of all articles; there was an average savings of $1280 …

A geothermal energy feasibility study has been performed for the City of Ouray, Colorado, to determine the potential economic development opportunities to the City. The resource assessment indicates the resource to be associated with the Ouray fault zone, the Leadville limestone formation, the high thermal gradient in the area of the San Juan mountains, and the recharge from precipitation in the adjacent mountains. Four engineering designs of alternative sizes, costs, applications, and years of start-up have been defined to offer the City a range of development scales. Life cycle cost analyses have been conducted for cases of both public and private ownership. All systems are found to be feasible on both economic and technical grounds. 49 refs., 8 figs.

The H/sub 2/O-CHCl/sub 3/-H/sub 2/O liquid membrane system was characterized with respect to the effect on cation (K/sup +/) transport rate of salt concentration and anion type. A bulk liquid membrane cell was used. A mathematical model for cation flux is being developed for several cations, several macrocycles, and mixtures of two or three cations. Eu/sup 3 +/ was not transported by 18-crown-6, but its reduced from Eu/sup 2 +/ was. Cation transport properties of calixarenes are also being investigated. Emulsion membrane systems were studied as a way of increasing the cation transport. Pb/sup 2 +/ was found to be transported by dicyclohexano-18-crown-6 through the liquid membrane. Transport rates of metal cation nitrates were measured in a water-toluene-water emulsion membrane system. 14 figures, 7 tables. (DLC)

Monsanto Research Corporation is charged with processing encapsulated plutonium dioxide heat sources into radioisotopic thermoelectric generators (RTGs) to support deep-space missions. One of the problems associated with the sometimes protracted ground storage of these devices is the ingrowth of carbon dioxide and carbon monoxide in the gas phase due to the cyclical reaction established between the fuel (/sup 238/PuO/sub 2/) and the carbon impact body. This ingrowth proceeds according to the two equations: x(CO) + <PuO/sub 2/> = x(CO/sub 2/) + < PuO/sub 2-x/ and x(CO/sub 2/) + x < C > = 2x(CO), etc. To reduce this effect, a gas management system was instituted that enabled periodic removal of the generated CO and CO/sub 2/ with replacement by argon. The removal of these components was monitored and permitted an assessment of the degree of substoichiometry as well as its effect on the chemical activity of the CO and CO/sub 2/. This in turn was used to estimate the oxygen activity and to calculate ..delta.. anti G(O/sub 2/) as a function of stoichiometry.

A weekly publication, the Texas Register serves as the journal of state agency rulemaking for Texas. Information published in the Texas Register includes proposed, adopted, withdrawn and emergency rule actions, notices of state agency review of agency rules, governor's appointments, attorney general opinions, and miscellaneous documents such as requests for proposals. After adoption, these rulemaking actions are codified into the Texas Administrative Code.

A two-dimensional numerical model of a high-gain (electron-beam power > input laser beam power) free-electron laser (FEL) has been constructed which includes the effects of diffraction, refraction, and off-axis electron-beam current density and wiggler field variations. In this model, laser beam propagation is governed by a paraxial wave equation with FEL source terms. Conventional resonant electron analysis is used to represent the trapping and deceleration of electrons by the electromagnetic field. The trapped electron-beam current density is forced to decrease as the size of the trapping potential decreases so that detrapping can be simulated. The variable-parameter wiggler field is chosen so that synchronism can be maintained at a single, arbitrary radial position. The magnetic field varies at other radial positions in accordance with Maxwell's equations.
