Session II-G. Repository data base development

The development of a comprehensive technical data base is required before a final design of a geologic repository can be determined. Quantitative information regarding complex technical considerations comprises the data base, which supports a variety of activities. These activities include geologic characterization, design development, performance assessment, licensing, construction, operation, and decommissioning of a repository. The overall planning document describing these activities is the NWTS Program Plan, which is under final preparation. Testing (field, in situ, and laboratory) is the primary method for developing the pertinent data base needed to support final design activities. The following papers were presented at this session on repository data development: (1) acqusition of repository design data, 1981 progress; (2) tuff rock mechanics testing in G-tunnel at Nevada Test Site; (3) results from the Near-Surface Test Facility heater tests and block tests; (4) progress of rock-mechanics tests for designing a repository in basalt; (5) conclusions from the Stripa field tests; (6) hydrothermomechanical rock mass characterization using the heated block test; (7) measurement of long-term creep in salt pillars; and (8) Avery Island studies: comparison of numerical simulations and field measurements
