A rock brittleness index based on the postpeak energy release rate and damage surface characteristics for brittle hard rock

Deep Underground Science and Engineering, EarlyView.
This study examines energy evolution in rock rupture via triaxial direct shear tests, exploring the impact of confining pressure and temperature on fracture surface randomness. A novel energy‐based brittleness index is proposed, validated experimentally, and compared with existing methods for reliability and accuracy.

Thermal‐induced fracture evolution and acoustic signature of Beishan granite: Insights into tensile strength of barrier system for high‐level radioactive waste disposal

Deep Underground Science and Engineering, EarlyView.
The tensile strength of granite, a proposed host for nuclear waste, degrades severely above 400°C. We link this to specific microcracking patterns captured by acoustic emission, establishing a scientific basis for assessing repository safety under thermal load.

Review of aluminum solubility behavior in the Hanford 200 South West Area tanks targeted for retrieval

Environmental Progress &Sustainable Energy, EarlyView.
Abstract The behavior of aluminum‐bearing phases in tank wastes from the southwest quadrant of the Hanford Site's 200 West Area primarily determines solids accumulation, retrieval performance, and downstream processability. This review synthesizes historical tank characterization data, laboratory dissolution studies, and process‐relevant observations ...
