First-quarter report of neutron logging during the heating phase of the drift-scale test
The Drift-Scale Test (DST) is one of the thermal tests being conducted in the Exploratory Studies Facility (ESF). One of the purposes of the DST is to study, at the ESF, the coupled thermal- mechanical- hydrologic-chemical (TMHC) processes at the repository horizon of the potential high-level nuclear waste repository at Yucca Mountain, Nevada. The objectives, the test design, and the test layouts of the DST are included in the test design report by the Civilian Radioactive Waste Management System Management and Operation (CRWMS M&O) contractors. The configuration of the DST includes a declining observation drift driven mostly east and downwardmore »
