Geological problems in radioactive waste isolation - second worldwide review
The first world wide review of the geological problems in radioactive waste isolation was published by Lawrence Berkeley National Laboratory in 1991. This review was a compilation of reports that had been submitted to a workshop held in conjunction with the 28th International Geological Congress that took place July 9-19, 1989 in Washington, D.C. Reports from 15 countries were presented at the workshop and four countries provided reports after the workshop, so that material from 19 different countries was included in the first review. It was apparent from the widespread interest in this first review that the problem of providing a permanent and reliable method of isolating radioactive waste from the biosphere is a topic of great concern among the more advanced, as well as the developing, nations of the world. This is especially the case in connection with high-level waste (HLW) after its removal from nuclear power plants. The general concensus is that an adequate isolation can be accomplished by selecting an appropriate geologic setting and carefully designing the underground system with its engineered barriers. This document contains the Second Worldwide Review of Geological Problems in Radioactive Waste Isolation, dated September 1996

Geological problems in radioactive waste isolation
The problem of isolating radioactive wastes from the biosphere presents specialists in the fields of earth sciences with some of the most complicated problems they have ever encountered. This is especially true for high level waste (HLW) which must be isolated in the underground and away from the biosphere for thousands of years. Essentially every country that is generating electricity in nuclear power plants is faced with the problem of isolating the radioactive wastes that are produced. The general consensus is that this can be accomplished by selecting an appropriate geologic setting and carefully designing the rock repository. Much new technology is being developed to solve the problems that have been raised and there is a continuing need to publish the results of new developments for the benefit of all concerned. The 28th International Geologic Congress that was held July 9--19, 1989 in Washington, DC provided an opportunity for earth scientists to gather for detailed discussions on these problems. Workshop W3B on the subject, Geological Problems in Radioactive Waste Isolation -- A World Wide Review'' was organized by Paul A Witherspoon and Ghislain de Marsily and convened July 15--16, 1989 Reports from 19 countries have been gathered for this publication. Individual papers have been cataloged separately

MECHANICAL AND THERMAL DESIGN CONSIDERATIONS FOR RADIOACTIVE WASTEREPOSITORIES IN HARD ROCK
This report is one of a series documenting the results of the Swedish-American cooperative research program in which the cooperating scientists explore the geological, geophysical, hydrological, geochemical, and structural effects anticipated from the use of a large crystalline rock mass as a geologic repository for nuclear waste. This paper is broken down into the following 2 parts: (1) An appraisal of hard rock for potential underground repositories of radioactive waste; and (2) In situ heating experiments in hard rock--Their objectives and design

Geosciences program annual report 1978. [LBL Earth Sciences Division]
This report is a reprint of the Geosciences section of the LBL Earth Sciences Division Annual Report 1978 (LBL-8648). It contains summary papers that describe fundamental studies addressing a variety of earth science problems of interest to the DOE. They have applications in such diverse areas as geothermal energy, oil recovery, in situ coal gasification, uranium resource evaluation and recovery, and earthquake prediction. Completed work has been reported or likely will be in the usual channels. (RWR
