Abstract: Early in 1990, the Yucca Mountain Project Office (Project Office; presently the Yucca Mountain Site Characterization Project Office) of the U.S. Department of Energy (DOE) completed two prototype boreholes at Apache Leap, Arizona, to test dry drilling and coring techniques that will be used during site characterization activities at Yucca Mountain, Nevada. Staff of the Sample Management Facility (SMF), Technical and Management Support Services contractor, used the boreholes to test sample handling and geologic logging procedures. Results of this testing indicate that modifications to approved Project Office procedures will be necessary before site characterization commences. These modifications include reduction of paperwork, verification of drill depths, upgrade of equipment, and enhanced training of SMF field staff.
