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.

The participatory turn in radioactive waste management:Deliberation and the social-technical divide [PDF]

, 2015
National policies for long-term management of radioactive waste have for decades been driven by technical experts. The pursuit of these technocratic policies led in many countries to conflict with affected communities.

Phosphate and fluoride removal options for Hanford high‐level waste sludge processing

Environmental Progress &Sustainable Energy, EarlyView.
Abstract High‐phosphate and high‐fluoride sludges represent some of the most challenging waste streams within the Hanford High‐Level Waste (HLW) inventory due to solubility constraints, impacts on glass loading, and corrosion risks during vitrification.

Gas Network Development in Compact Bentonite: Key Controls on the Stability of Flow Pathways

Geofluids, 2019
Compacted bentonite is proposed as an engineered barrier material within facilities for the geological disposal of radioactive waste. Barrier performance and its interaction with a free gas phase must be considered as part of sound repository design ...

Robust Control Using a Matrix Converter to Enhance Wind Turbine Systems

Energy Science &Engineering, EarlyView.
This study uses a more efficient and effective solution to improve the operational performance of a wind turbine‐based power system. This system uses a doubly fed induction generator and relies on a matrix converter and fractional‐order proportional–integral controller.
