Title: Summary of geochemical measurements taken in an around the G-Tunnel underground facility, NTS

Technical Report ·
OSTI ID:60049

A summary of field and supporting laboratory data collected in and around the G-Tunnel Underground Facility (GTUF) on the Nevada Test Site (NTS) is presented to provide information concerning the ability of tuffs to contain radioactive wastes. The Nevada Nuclear Waste Storage Investigations (NNWSI) Project is investigating the possibility of constructing a high-level nuclear waste repository within similar tuffs at Yucca Mountain on and adjacent to the NTS. The GTUF investigations included geomechanical measurements covering: in situ stresses, intact rock and joint slip strengths, rock-mass deformational behavior, rock-mass thermal and thermomechanical properties, and rock-mass behavior associated with rock dewatering and fracture flows. The summary primarily contains data and describes behavioral trends for the tuffs as obtained in four major NNWSI-sponsored field testing efforts. NNWSI-sponsored laboratory data and other non-NNWSI-sponsored information obtained from tuffs in the immediate vicinity of the GTUF are included to augment the findings. 81 refs., 27 figs., 22 tabs.
