The rock mechanics testing performed at the Earth Mechanics Institute of the Colorado School of Mines for Rockwell Hanford Operations under Subcontract SA-917 is summarized. Cores were supplied from drill hole DC-8 on the Hanford Site, characterized geologically, and tested for thermal and physical properties for designing long-term underground storage of radioactive waste materials. This report presents the approved test procedures, results, and data analysis for this test series. Results indicate significantly lower strengths for drill hole DC-8 than determined for drill hole DC-6 or for the drill holes reported on in our fiscal year 1978 (FY 78) tests. Trends, however, were found to be similar between drill holes DC-6 and DC-8, and it is hoped more definitive conclusions can be found following completion of the final series of tests.

This report is a summary of the rock mechanics testing done at the Earth Mechanics Institute of the Colorado School of Mines for Rockwell Hanford Operations under Subcontract SA-917. Cores were supplied from drill hole DC-6 on the Hanford Site, characterized geologically, and tested for thermal and physical properties for designing long-term underground storage of radioactive waste materials. This report presents the approved test procedures, results, and data analysis for this test series. Results indicated thermophysical properties similar to those of previously tested basalt cores from the Hanford area, but showed no significant trends; thus, generalizations are risky at this time. However, density was found to be a good guide to thermal and physical properties--higher density basalt cores showed significant improvements in physical and thermal properties.

The rock mechanics testing performed at the Earth Mechanics Institute of the Colorado School of Mines for Rockwell Hanford Operations under subcontract SA-917 is summarized. Cores were supplied from drill hole DC-4 on the Hanford Site, characterized geologically, and tested for thermal and physical properties for designing long-term underground storage of radioactive waste materials. The approved test procedures, results, and data analysis for this test series are presented. Uniaxial and triaxial results indicate strengths similar to drill hole DC-6, but significantly higher than drill hole DC-8. Trends with density, depth, confining pressure, and temperature, however, were similar for the three drill hole locations tested.

Meeting our energy needs and protecting the quality of our environment are complementary parts of our national energy planning. The search for energy supplies and the development of new energy sources must go hand-in-hand with clean air, clean water, and a healthy environment. The Office of Environment (EV) has a major responsibility in the Department of Energy (DOE) for assuring that environmental concern are translated into environmental programs and commitments. EV studies the environmental, health and safety effects of all DOE energy programs, overviews the environmental aspects of these programs, and ensures their consistency with environmental and safety laws, regulations, and policies. EV programs support the Department's efforts to achieve the best balance between energy availability and environmental acceptability. This document briefly describes EV activities, summarizes programs for FY 1979, and identifies responsible divisions and offices. Included are funding levels and budgetary trends for EV programs and the energy technologies they support, as well as institutions responsible for performing the EV activities.

The U.S. Department of Energy (DOE) focuses energy Research and Development efforts on new and promising ways to provide for our future energy needs. This document focuses on DOE's programs and projects related to the nation's Fossil Energy resources: coal, oil, natural gas and oil shale. Fossil Energy programs have grown rapidly from about $58 million in FY 1973 to the $802 million requested for FY 1979. As those programs have matured, there have been significant shifts in emphasis. For example, by FY 1979, gasification technologies will have matured sufficiently to enter the demonstration phase. Then we will have to make critical decisions as to which candidate processes to pursue and to encourage industry's active participation as early as possible. We will present the rationale for those changes and others at the beginning of each section describing a particular grouping of similar projects, e.g., coal liquefaction. We will then discuss each project and present its current status along with past and future milestones. Emphasis is on projects with early payoff potential, particularly the direct utilization of coal. However, this near-term emphasis will not overshadow the need for a stong technological base for development of longer-term promising technologies and the need …

This report summarizes recent technical progress in the major areas of study. Because a considerable variety of work has been performed this year they authors first give brief synopses of individual research projects categorizing them as to their relevance to the general areas of plasma stability analyses, plasma heating or basic plasma physics. Next, they discuss these projects as they relate to and support the various DOE experimental programs. The DOE experimental programs are: (1) toroidal confinement systems; (2) open confinement systems; and (3) alternative concepts (EBT, Spheromak, field reversed mirrors and punches).
