Domain‐Knowledge‑Guided Rule Extraction for Governing Nepheline Amount in High‑Level Waste Glasses

International Journal of Applied Glass Science, Volume 17, Issue 4, October 2026.
ABSTRACT Nepheline crystallization during canister centerline cooling is one of the most constraining factors limiting waste loading in high‐level waste (HLW) borosilicate glasses. Existing predictive models treat nepheline formation as a binary outcome, yet durability degradation depends continuously on nepheline fraction.

Geological disposal of high-level radioactive wastes

, 1979
The importance of nuclear powered electricity generation in helping to solve Canada's future energy requirements is well documented. It is also well known that whereas nuclear reactors are technically feasible, they also involve serious human and environmental problems which remain to be solved.

Optical Basicity of Glasses: Review and Application in Nuclear Glass Formulation

International Journal of Applied Glass Science, Volume 17, Issue 4, October 2026.
A self‐consistent set of optical basicity (OB) values was compiled and evaluated for 95 binary oxides using electronegativity, ionic–covalent, and optical‐property approaches, providing a robust basis for estimating the basicity of complex compounds and glasses.

Experimental activation assessment of open‐type yoke in a PET cyclotron by non‐destructive/destructive γ‐ray measurement approaches

Medical Physics, Volume 53, Issue 9, September 2026.
Abstract Background During decommissioning of positron emission tomography (PET) cyclotron facilities, metallic components—including the iron yoke—are typically classified as radioactive waste, incurring substantial disposal costs. In contrast to concrete, standardized decommissioning procedures for metallic components have not yet been established ...

Recent Development in Solar‐to‐Hydrogen Conversion Systems

WIREs Energy and Environment, Volume 15, Issue 3, September 2026.
This review compares three solar‐driven hydrogen production methods, photocatalysis (PC), photoelectrochemical cells (PEC), and photovoltaic–electrochemical (PV–EC) systems by examining their mechanisms, materials, stability, and efficiency. Nanocrystal‐based PC catalysts achieved the highest quantum efficiency (94%), while PV–EC and Si nanowire PEC ...

Spatial Variability in Recent Phototroph Production in a Large, Fluvial Lake Driven by Local Land‐Use Changes (St. Lawrence River, Canada)

Freshwater Biology, Volume 71, Issue 9, September 2026.
ABSTRACT Increases in lake production and the abundance of cyanobacteria have been reported in many temperate freshwater systems, with their rise typically attributed to elevated nutrient influx or climate change. On the St. Lawrence River (SLR), recent evidence suggests that cyanobacterial abundances have increased since ca. 2000, although the precise

Spatial distribution of the stochastic discontinuities of Shazaoyuan granite masses in Beishan

工程科学学报
Shazaoyuan granite masses are a substitute location for high-level radioactive waste disposal in China. The widely distributed stochastic discontinuities in the granite bodies in this area are crucial factors that control rock deformation and nuclide ...
