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 ...

Beyond electricity generation: Nuclear power plants as circular chemical manufacturing hubs for plastic waste valorization

Environmental Progress &Sustainable Energy, EarlyView.
Abstract Large nuclear power plants have traditionally been regarded as facilities dedicated to electricity generation. This study proposes a systems‐level concept in which they function as circular chemical manufacturing hubs integrating plastic waste valorization, hydrogen production, carbon utilization, and downstream polymer synthesis within a ...
