Selection of a preferred initial access for the exploratory studies facility

Description

An issue of interest to the Yucca Mountain Site Characterization Project Office (YMPO) has been selection of the preferred location for initial access to the Exploratory Studies Facility (ESF) in the event that the U.S. Department of Energy (DOE) elected to proceed with a phased approach to facility development. A task force to conduct an assessment and prepare a recommendation of the preferred initial location (north or south) for starting underground in situ tests at Yucca Mountain was initiated by YMPO to address this issue. The task force addressed geotechnical issues associated with the presence of disqualifying conditions at the ... continued below

Description

An issue of interest to the Yucca Mountain Site Characterization Project Office (YMPO) has been selection of the preferred location for initial access to the Exploratory Studies Facility (ESF) in the event that the U.S. Department of Energy (DOE) elected to proceed with a phased approach to facility development. A task force to conduct an assessment and prepare a recommendation of the preferred initial location (north or south) for starting underground in situ tests at Yucca Mountain was initiated by YMPO to address this issue. The task force addressed geotechnical issues associated with the presence of disqualifying conditions at the site, the inability of the site to meet qualifying conditions, and the potential for unexpected geologic conditions at the site. The task force compared the north and south ramp accesses of the ESF to determine whether either access would be more likely to provide relevant information about potential site unsuitability. The task force did not address issues such as design time or construction costs. Within the aforementioned context, a balanced evaluation of currently available geotechnical information and issues failed to provide a clear mandate for either ramp as the preferred initial ESF access. Neither access was clearly superior in providing geotechnical information to resolve site suitability issues. The task force therefore recommended that other appropriate programmatic factors, such as schedule, be used as a basis in determining the choice of a preferred, initial ESF access in the event of phased construction.
