Study of multiphase flow useful to understanding scaleup of coal-liquefaction reactors. Technical progress report, September 1, 1981-November 30, 1981
The major portion of the time spent on this project for this quarter involved specifying and ordering the equipment required to construct the 13 inch inside diameter column. The superstructure has been constructed in the laboratory and all major equipment has been ordered. In addition a series of dynamic gas disengagement experiments have been performed using the six inch inside diameter column. The major objective of these experiments was to determine whether the distribution has any effect on the bubble rise velocities. No major difference was found when the data for a porous plate and a sieve plate was compared.

Subsurface evaluation of the geopressured-geothermal Chloe Prospect, Calcasieu Parish, Louisiana
A 123 square mile area approximately 10 miles east of Lake Charles, Louisiana, has been studied to assess its potential geopressured-geothermal resources. Subsurface information was used to study the structure and stratigraphy of the area as they related to the development of geopressured aquifers. The Middle Frio Hackberry wedge was found to contain the geopressured-geothermal reservoir sand, as well as the shales responsible for the origin and sealing of the geopressured strata. The major reservoir within the wedge is the Hackberry massive A sand.

Summaries of the FY 1981 applied mathematical sciences research program
Applied Mathematical Sciences serves as the DOE focal point for monitoring and advancing the state of the art in mathematics, statistics, and computer science. Several DOE mission programs develop and refine specific techniques from the applied mathematical sciences applicable to their immediate needs. In contrast, Applied Mathematical Sciences concentrates on more broadly based, continuing needs throughout the DOE community. Emphasis is placed on research basic to the analysis, development, and use of large-scale computational models; the management and analysis of large, complex collections of information; and the effective use of DOE computing resources. The purpose of this research is not to improve existing technologies and methodologies, but rather to render them obsolete. Each part of the Applied Mathematical Sciences activity has been designed with the help and advice of leading mathematicians and computer scientists from universities, industry, and DOE laboratories to assure the broadest and greatest impact on the nation's energy R and D enterprise. Many of them are expert in industry's needs in the relevant areas. Close liaison is maintained with other federal agencies in the selection of areas of emphasis and of individual research tasks. This is high leverage research. In favorable cases, the results may be of …

Summary: analysis of alternative FBR development strategies
This report summarizes the comparative evaluation of alternative strategies for the development of the commercial fast breeder reactor (FBR) in the United States. For planning purposes, a range of possible FBR development paths called strategies were selected for evaluation. These strategies, designed to be technically and economically feasible, were expressed in terms of the timing and nature of facilities/research and development programs required to reach full power operation of the first commercial FBR. Four of the seven strategies resulted in a large (1457 MWe) FBR as an end point, the other three in a 1000-MWe plant. Probability distributions were calculated for total strategy costs and time to completion. For the seven strategies analyzed, the costs (discounted 1980 dollars) ranged from $1.8 billion to $4.9 billion; the completion times ranged from 24 to 55 years.

Survey of agents and techniques applicable to the solidification of low-level radioactive wastes
A review of the various solidification agents and techniques that are currently available or potentially applicable for the solidification of low-level radioactive wastes is presented. An overview of the types and quantities of low-level wastes produced is presented. Descriptions of waste form matrix materials, the wastes types for which they have been or may be applied and available information concerning relevant waste form properties and characteristics follow. Also included are descriptions of the processing techniques themselves with an emphasis on those operating parameters which impact upon waste form properties. The solidification agents considered in this survey include: hydraulic cements, thermoplastic materials, thermosetting polymers, glasses, synthetic minerals and composite materials. This survey is part of a program supported by the United States Department of Energy's Low-Level Waste Management Program (LLWMP). This work provides input into LLWMP efforts to develop and compile information relevant to the treatment and processing of low-level wastes and their disposal by shallow land burial.

Survey of Radionuclide Distributions Resulting from the Church Rock, New Mexico, Uranium Mill Tailings Pond Dam Failure
An intensive site survey and on-site analysis program were conducted to evaluate the distribution of four radionucliGes in the general vicinity of Gallup, New Mexico, subsequent to the accidental breach of a uranium mill tailings pond dam and the release of a large quantity of tailings pond materials. The objective of this work was to determine the distribution and concentration levels of {sup 210}Pb, {sup 226}Ra, {sup 230}Th, and {sup 238}U in the arroyo that is immediately adjacent to the uranium tailings pond (pipeline arroyo) and in the Rio Puerco arroyo into which the pipeline arroyo drains. An intensive survey between the United Nuclear Corporation (UNC) Church Rock Mill site and the New Mexico-Arizona state border was performed. Sampling locations were established at approximately 500-ft intervals along the arroyo. During the weeks of September 24 through October 5, 1979, a series of samples was collected from alternate sampling locations along the arroyo. The purpose of this collection of samples and their subsequent analysis was to provide an immediate evaluation of the extent and the levels of radioactive contamination. The data obtained from this extensive survey were then compared to action levels which had been proposed by the Nuclear Regulatory Commission …

Technique for measuring the fast /sub 3/He/sup + +/ distribution during /sub 3/He/sup + +/ minority ICRF heating
A technique for measuring the fast /sub 3/He/sup + +/ distribution during /sub 3/He/sup + +/ minority ICRF heating is discussed. The technique involves the use of 10 to 100 keV neutral helium beams to neutralize the fast /sub 3/He/sup + +/ ions by double charge exchange (/sub 3/He/sup + +/ + /sub 4/He/sup 0/ ..-->.. /sub 3/He/sup 0/ + /sub 4/He/sup + +/). The neutralized fast /sub 3/He atoms then escape from the plasma and are detected by conventional neutral particle analyzing apparatus. By the use of such a technique, the effectiveness of the coupling of the ion cyclotron waves to the /sub 3/He/sup + +/ minority could be measured.

Theory of Moessbauer line broadening due to diffusion
We have calculated the line broadening of the Moessbauer line due to diffusion of Moessbauer atoms via single vacanices. We take into account the perturbation of vacancy jumps in the neighbourhood of an impurity Moessbauer atom (e.g. Fe in Al) using the 5-frequency model. The anisotropy of the line width is given by the Fourier transform of the final distribution of a Moessbauer atom after an encounter with a vacancy. This distribution is calculated by Monte Carlo computer simulation. 3 figures, 1 tables.

Thermal-hydraulic analysis of the dual-function gamma thermometer
A computational study was performed to investigate the potential of a modified gamma thermometer (GT) as a monitor of both the localized power level and the core cooling in a PWR. The volumetric heat source within the thermometer was updated to include heat deposited by neutrons as well as heat deposited by decay gammas and neutron-induced gammas. Utilizing this source, along with a more detailed thermal-hydraulics model, a series of thermal-hydraulic calculations were performed to simulate certain reactor transients of interest (i.e., reactor scram, LOCA, etc.) in order to characterize the gamma thermometer response relative to power level monitoring and adequate core cooling indication. Results of this study reaffirm the feasibility of utilizing the GT as a dual-function (power level and adequate core cooling capacity) measurement device, with each function accomplished virtualy independent of the other. The study also indicates that there is a thermal-hydraulic regime for which the GT would no longer give easily interpretable signals.

Third-party financing of central-receiver repowering projects
An innovative third party financing approach for the first solar thermal repowering plants is investigated that may reduce the need for direct DOE cost sharing during the early application of central receiver technology by industry. Third party refers to a corporation, partnership, or a joint venture that can take advantage of existing financial incentives. The available financial incentives are summarized, including the guaranteed market for central receiver power provided by Section 210 of the Public Utility Regulatory Policy Act, and federal and state tax credits and depreciation schedules. The economics of third party central receiver repowering plant financing is analyzed, and the case history of the Arizona Public Service Utility Saguaro Plant No. 1 is used as an example. Finally, a sensitivity analysis examines the effects of variations of different financial parameters on the return on investment. It is found that a substantial portion of investment equity can be recovered in the first few years of plant operation, and good future years cash flows appear possible. Third party financing appears capable of helping stimulate mass production of heliostats and a rapid transfer of central receiver technology to utilities and industry, with attending economic benefits.

Transportation study for the Geysers Geothermal Resource Area
Potential cumulative impacts on the transportation system are assessed and recommendations are made as to options for handling future transportation development. The area is served by state highways, county roads, and an internal network of private roads. Access into the area is limited, and the roads must handle a variety of traffic including an unusually high percentage of heavy trucks transporting construction equipment and materials, hazardous chemicals, and toxic wastes. In conducting the transportation study public documents on geothermal power plant developments were researched and field trips to inspect the transportation facilities were made. People who have a special interest in the transportation system were also interviewed. In addition, traffic, accident, and road data were analyzed. Traffic forecasts based on projected geothermal resource develpoment were made. All access roads are of substandard design and efficient in structural adequacy. With projected traffic at 40% above the current level for most of the next six years, it is expected that cumulative impacts will cause accelerated degradation of the existing roads.

Tritium permeation in fusion reactors: INTOR
Tritium permeation through the first wall of advanced fusion reactors is examined. A fraction of the D-T which bombards the first wall as charge exchange neutral particles will permeate through the first wall and enter the coolant. Calculations of the steady state permeation rate for the US INTOR Tokamak design result in values of less than or equal to 0.002 grams of tritium per day under the most favorable conditions. For unfavorable surface conditions the rate is greater than or equal to 0.1 g/day. The magnitude of these permeation rates is critically dependent on the temperatures and surface conditions of the wall. The introduction of permeation barriers at the wall-coolant interface can significantly reduce permeation rates and hence may be desirable for reactor applications.
