Pressure phase lines and enthalpies for the. cap alpha. -. beta. and. beta. -liquid transitions in beryllium
The effect of hydrostatic pressure on the ..cap alpha..-..beta.. and ..beta..-liquid transition temperatures in Be was measured in a gas pressure system. Differential thermal analysis was used in the pressure range from 0.1 MPa to 0.7 GPa. For the ..cap alpha..-..beta.. transition, dT/dP = 43 +- 7 K/GPa; for the ..beta..-liquid transition, dT/dP = 35 +- 7 K/GPa. Although it is possible that large systematic errors may arise from experimental procedures, our results are seriously at odds with those of other investigators. Transition enthalpies for the ..cap alpha..-..beta.. and ..beta..-liquid transitions were 1.9 +- 0.2 and 2.2 +- 0.2 kcal/g.m., respectively, at a pressure of 0.1 MPa.

Construction features of the exploratory shaft at Yucca Mountain
The Exploratory Shaft (ES) at Yucca Mountain is planned to be constructed during 1985 and 1986 as part of the detailed site characterization for one of three sites which may be selected as candidates for location of a high-level radioactive waste repository. Conventional mining methods will be used for the shaft sinking phase of the ES project. The ES will be comprised of surface support facilities, a 1480-ft-deep circular shaft lined with concrete to a finished inside diameter of 12 ft, lateral excavations and test installations extending up to 200 ft from the shaft, and long lateral borings extending up to 2300 ft from the shaft. The estimated time for sinking the shaft to a total depth of about 1480 ft and completing the lateral excavations and borings is about two years. The major underground development planned for the primary test level at a depth of 1200 ft consists of the equivalent of 1150 ft of 15- by 15-ft drift. The total volume of rock to be removed from the shaft proper and the lateral excavations totals about 1/2 million cubic feet. Construction equipment for the shaft and underground excavation phases consists of conventional mine hoisting equipment, shot hole and …

Federal geothermal royalty income derived from the benefits of government-sponsored R and D
The ability of Federally-sponsored geothermal R and D to, in effect, pay for itself through increased royalty payments resulting from enhanced resource development on Federal lands is investigated. The report concludes that achievement of current Federal R and D objectives is likely to result in significant royalty returns to both state and Federal governments. These returns are measured in terms of the increase in royalty payments attributable to the achievement of Federal R and D objectives, as opposed to those payments which would be expected from the on-going low level of private sector R and D absent any Federal support. To perform this analysis, an integrated approach sequentially addresses (1) future wildcat drilling activity, (2) the number and quality of new resource discoveries, (3) the technological potential (megawatts) of the discovered resource base, and the likelihood that it will be developed, and (4) the royalty income which will be generated as a result of development of Federal land. This computer-based modeling approach has been developed by Technecon over the last 5 years under the sponsorship of both the Department of Energy and private industry. Portions of this model have been specially modified and updated during the course of this study.

Evaluate fundamental approaches to longwall dust control. Phase III report
The overall objective of the contract is to evaluate the effectiveness of available dust control technology for double-drum shearer longwall sections in a coordinated, systematic program at a few longwall test sections and to make the results available to the entire coal mining industry. This program is investigating nine different dust control techniques. These nine subprograms encompass a broad range of dust control measures ranging from administrative controls to new hardware. They span not only presently employed methods but also those recently adopted in the United States and those proposed for the future. This report documents the Phase III effort on each of the subprograms. For clarity, the report is divided in sections by subprogram as follows: Section 2, Subprogram A - passive barriers/spray air movers for dust control; Section 3, Subprogram B - practical aspects of deep cutting; Section 4, Subprogram C - stage loader dust control; Section 5, Subprogram D - longwall automation technology; Section 6, Subprogram E - longwall application of ventilation curtains; Section 7, Subprogram F - reversed drum rotation; Section 8, Subprogram G - reduction of shield generated dust; Section 9, Subprogram H - air canopies for longwalls; and Section 10, Subprogram I - mining …

NNWSI waste form performance test development
A test method has been developed to measure the release of radionuclides from the waste package under simulated NNWSI repository conditions, and to provide information concerning materials interactions that may occur in the repository. Data from 13 weeks of unsaturated testing are discussed and compared to that from a 13-week analog test. The data indicate that the waste form test is capable of producing consistent, reproducible results that will be useful in evaluating the role of the waste in the long-term performance of the repository. 6 references, 3 figures.

Geologic and hydrologic characterization and evaluation of the Basin and Range Province relative to the disposal of high-level radioactive waste. Part I. Introduction and guidelines
The US Geological Survey`s program for geologic and hydrologic evaluation of physiographic provinces to identify areas potentially suitable for locating repository sites for disposal of high-level nuclear wastes was announced to the Governors of the eight states in the Basin and Range Province on May 5, 1981. Representatives of Arizona, California, Idaho, New Mexico, Nevada, Oregon, Texas, and Utah, were invited to cooperate with the federal government in the evaluation process. Each governor was requested to nominate an earth scientist to represent the state in a province working group composed of state and US Geological Survey representatives. This report, Part I of a three-part report, provides the background, introduction and scope of the study. This part also includes a discussion of geologic and hydrologic guidelines that will be used in the evaluation process and illustrates geohydrologic environments and the effect of individual factors in providing multiple natural barriers to radionuclide migration. 27 refs., 6 figs., 1 tab.

Farm scale electrical power production from animal waste. Volume I. Final report, 30 June 1981-30 December 1983
A 1 1/2 (dry) tons per day biodigester cogeneration plant has been designed and constructed. This project is part of a federal program to promote energy conservation and the use of non-conventional energy resources. The main purpose of the project is to demonstrate that a dairy farm can generate its own power and supply excess power to a local utility. Such a facility can produce significant energy savings to livestock farms and small communities by allowing them to get energy from raw animal and human waste. Also, an odorless by-product is produced that is nearly pathogenically free and has the possibility of several end uses such as: fertilizer and soil conditioner, protein-rich animal refeed, livestock bedding material, and aquatic food for fish farming. 53 references, 18 figures, 4 tables.

Performance evaluation of a ceramic cross-flow filter on a bench- scale coal gasifier. First quarterly project report, October 1, 1984--December 31, 1984
The Department of Energy is currently supporting a program that will aid in the development of cross flow filtration technology as applied to combined cycle power generation with coal gasification. The stated overall goal is to gain information on both the operational and economic feasibility of the implementation of cross flow filtration in various gasifier options. Westinghouse has prepared a comprehensive program that will lead directly to these program goals in an efficient manner.
