... ABSTRACT: The Ghareb Formation in the Yasmin Plain of Israel is under investigation as a potential disposal rock for nuclear waste disposal. Triaxial deformation tests and hydrostatic water-permeability tests were conducted with samples of the Ghareb to assess relevant thermal, hydrological...

... ABSTRACT: Salt has long been considered as a potential host rock for the geological disposal of radioactive waste because of its favorable properties, including self-sealing, low permeability and high thermal conductivity. The feasibility of nuclear waste disposal within salt formations has...

...1. INTRODUCTION The Blue Ribbon Commission (BRC) on America s Nuclear Future Report to the Secretary of Energy (2012) identified the urgent need for the US to develop a new strategy for long-term disposal of the tens of thousands of tons of spent nuclear fuel currently housed at dozens of locations...

... Abstract: Rock salt provides the world's best barrier, and has thus long been considered as a host rock for nuclear waste repositories. Salt domes have vertical extensions of several kilometres and are consequently well-suited for deep borehole disposal, as an alternative to a mined...

... Abstract: Deep-borehole disposal has received increased attention in recent years as a potential strategy for the long-term disposal of nuclear waste. The target disposal interval for the deep-borehole option is granitic rock at depths between 3 and 5 km below the surface. The feasibility...

.... The stability of mines deteriorates when exposed to moisture. On the other hand, due to more stringent Environmental Protection Agency (EPA) regulations slurry backfilling of mines as one of alternatives for disposing fine coal waste has attracted more attention. Slurry backfilling consists of pumping coal fine...

... Abstract With an abundance of scientific information in hand, what are the remaining geomechanics issues for a salt repository for heat-generating nuclear waste disposal? The context of this question pertains to the development of a license application, rather than an exploration...

... as in the surrounding salt rock mass due to the nonexcludable infiltration of pore fluids from the waste. The Lux/Wolters constitutive model was developed not only specially for this question, but also for other purposes at Chair in Waste Disposal and Geomechanics of Clausthal University of Technology. This model...

... Abstract Posiva in Finland and SKB in Sweden are preparing for spent nuclear fuel disposal in crystalline bedrock. Disposal relies on the geological KBS-3 multiple barrier concept. In this concept surrounding rock mass is considered as one barrier preventing radionuclide transportation...

... that was recently chosen as a host formation for the disposal of high-level nuclear waste in Switzerland [1]. This clay rock has several advantageous characteristics for nuclear waste isolation, such as extremely low permeability, high sorption capacity and the potential for self-sealing. However, its relatively...

... of this assessment model, it is applied to a number of areas representing diverse geology in North America. Deep slurry injection is a process of solid waste disposal that is used by the petroleum industry to permanently dispose of non-hazardous oilfield solid waste [1]. This process consists of grinding the solid...

... to dispose of significant volumes of drill cuttings and fluids into an unconsolidated formation, it is necessary to fracture the formation. A number of injection mechanisms are possible; and the dominating mechanism depends on the leak characteristics of the disposal formation, the direction of minimum...
