Repository data base development

Developing a data base for repository design requires the planning, design, execution, and interpretation of tests and experiments. This is a complex set of activities involving a variety of scientific and engineering disciplines. In the limited time available in this session, only a small sampling of this set of activities can be presented. The subjects chosen for presentation in this session include: a discussion of rock mechanics planning for multiple geologic media, results of ongoing rock mechanics investigations in salt and basalt, results from crystalline rock investigations in Sweden, development of basic rock properties for tuff, and fluid behavior in salt and tuff. The titles of the eight papers presented are: (1) Rock Mechanics in the National Waste Terminal Storage Program; (2) Creep of Rock Salt; (3) Rock Mechanics Strategies to Support Repository Design in Basalt; (4) Status of Test Results from Stripa Experiments; (5) Thermal and Mechanical Properties of Silicic Tuffs; (6) In Situ Tuff Water Migration/Heater Experiment; (7) Fluid Migration Studies in Salt; (8) Migration of Fluid Inclusions in Polycrystalline Salt Under Thermal Gradients in the Laboratory and in Salt Block II
