First principles simulation of cement for nuclear waste disposal
The immobilization of wastes that arise from the decommissioning of the UK civil nuclear program is a significant challenge facing both industry and researchers. The current plan for nuclear industry is to dispose of wastes within a deep underground facility and to use cement to immobilise many of …

Analysis and evaluation of three promising nuclear waste disposal options
Disposal of high level nuclear waste has evoked much interest among scientists, engineers and society at large. Numerous schemes have been proposed in this regard and a few have been analyzed thoroughly. However, these schemes have been found to be valid only under very specific environmental …

Effective thermal conductivity measurements relevant to deep borehole nuclear waste disposal
… proposed for use in and around canisters for disposal of high level nuclear waste in deep boreholes. This information is required to insure that waste temperatures will not exceed tolerable limits. Such experimental verification is essential because analytical models and empirical correlations …

Analytical Modeling of Bentonite Swelling and Numerical Reactive Transport Modeling in Nuclear Waste Disposal Systems
… widely used as buffer and backfill materials for nuclear waste disposal in last few decades. The main reasons of bentonite being selected for buffer and backfill materials include its low hydraulic permeability and high plasticity, which can restrict the transport of nuclear waste through the …

Radium cycling in groundwater : implications for bioremediation and tracer studies
… as hydraulic fracturing, uranium mining, and nuclear waste disposal poses significant public and ecological health risks. While occurrence of Ra in groundwater is concerning for public health and safety reasons, Ra is also a powerful tracer for calculating groundwater discharge and pollutant …

Preliminary design and analysis for selected problems in deep borehole disposal of spent nuclear fuel
… have generated interest in deep boreholes as a nuclear waste disposal option for all or part of the U.S. high-level waste inventory. Many design elements of deep borehole disposal have not yet been solidified, and there has not yet been a systematic analysis of the logistics necessary to …

The use of mediation to resolve environmental disputes in South Africa and Switzerland
… about mediation experiences in Switzerland over nuclear waste disposal. Nevertheless, this aforementioned case study shows that the Swiss decision-making system offers a good basis for mediation procedures in areas of politics where there is yet little participation as longs as certain …

Quantifying Iodine-129 Environmental Releases and Surface Water Concentrations at Nuclear Fuel Recycling Facilities
… long-term dose contributors in high-level nuclear waste disposal models, and an important contaminant at sites currently undergoing remediation like Savannah River and Hanford. This is in part due to its environmental mobility, its 15.7 million-year half-life, and its potential for …

Decision making in nuclear waste management:the use of the synoptic approach
… approach within decision making concerning nuclear waste management. The synoptic approach to decision making refers to an approach to rational decision making that assumes as an ideal, comprehensiveness of information and analysis. Two case studies are examined in which a high degree of …

Radioisotope Inventory Of Spent Nuclear Fuel In Mathematica
While nuclear reactors in the United States have produced economy-driving power for several decades, they have also left behind a significant amount of spent nuclear fuel. The federal government, ultimately responsible for this spent fuel, has a history just as long in attempting to effectively …

Mechanisms of Interaction Between Hydraulic and Natural Fractures in Shale Rocks
… oil and gas development in shale formations, and nuclear waste disposal, among others. In all these applications, controlling fracture propagation and interaction is essential for ensuring operational efficiency, safety, and long-term integrity of the system. This thesis presents a comprehensive …

Electrochemical and Modelling Studies on Simulated Spent Nuclear Fuel Corrosion under Permanent Waste Disposal Conditions
… safety assessment models for the deep geological disposal of spent nuclear fuel require a fundamental understanding of the corrosion of spent fuel in a failed waste container. The overall research goal of this project is to investigate the corrosion of simulated spent fuel under permanent disposal …
