An underground structure known as X-tunnel was investigated for the viability as an underground deep based missile system that included the capability to maintain survivability following...

A Note on Physical Modeling Approach for Assessment of Excavation Techniques
With the growing interest in utilizing underground space, the need for quantitative and qualitative assessment of excavation techniques to dictate the best choice for mining is now becoming...

Role of Fracture Zones in Controlling Hydraulic Head and Groundwater Flow?Experience from Site Characterization Program in Finland
The preliminary site investigations for the final disposal of HLW produced by TVO have been carried out during 1987 - 1992 in five areas. All the areas consist of Precambrian crystalline...

Prioritization of ESF Testing and Integration with Design and Construction
The developmental strategy for underground site characterization testing in the Exploratory Studies Facility (ESF) of the Yucca Mountain Site Characterization Program is outlined. The...

Control of Tracers, Fluids, and Materials for the Yucca Mountain Site Characterization Project
This paper describes use and control of tracers, fluids, and materials (TFM) at the Yucca Mountain Site Characterization Project. Management of TFM is necessary to ensure that site characterization...

Modeling of the Ventilation for Emplacement Drift Re-Entry and Rock Drying
Different ventilation scenarios were analyzed for a hot repository with a 114 kw/Acre heat load, to determine the time required to cool a drift to the point where the temperature of the...

Structural Character of the Ghost Dance Fault, Yucca Mountain, Nevada
Detailed structural mapping of an area that straddles the southern part of the Ghost Dance Fault has revealed the presence of several additional subparallel to anastomosing faults. These...

Geohydrologic Data and Models of Rainier Mesa and Their Implications to Yucca Mountain
The geohydrologic data collected at Rainier Mesa provide the only extensive observations in tunnels presently available on flow and transport in tuff units similar to those of a potential...
