Preliminary near-field environment report; Volume 1, Technical bases for EBS design

Large Block Test Final Report

“…Summing up a number of the earlier tests on tuff specimens from the proposed repository horizon, Wilder (1993) Martin et al (1993) have performed ultrasonic velocity and uniaxial compressive strength measurements on six Topopah Spring tuff specimens. Their strength data are not comparable to ours because they used a much slower loading rate (10-9/s), but the velocity data are comparable.…”

Near-field/altered-zone models report

“…The Preliminary Near-Field Environment Report, Volume I: Technical Bases for EBS Design was published in 1993 to summarize, in a form that could be readily used by repository designers and analysts, the state of knowledge of expected near field conditions (Wilder, 1993). This volume was revised in 1997 and renamed the Near-Field and Altered-Zone Environment Report, Volume I: Technical Bases for EBS Design to emphasize the importance of thermally driven coupled processes in the host rock (Wilder, 1997).…”

Performance Assessment Modeling for Savannah River Glass HLW Disposal in a Potential Repository at Yucca Mountain

“…The local groundwater chemistry in the vicinity of the repository will likely be dominated by the host rocks 4 and the incoming silica concentration Q Inflow is therefore expected to be close to cristobalite saturation at the ambient temperature. Cristobalite is a common constituent of the host rocks at Yucca Mountain.…”
