The application of chemistry to the technological requirements of the mineral industry is attended by problems of communication, isolation and application. Examples of research related to mineral exploration, underground fires, and the treatment of refractory ores suggest that the effective mineral chemist must learn the language of geology, metallurgy and engineering; that he must extend his s...

The transmutation of spent nuclear fuel is considered as a prospective alternative concept to the current concept based on the non-reprocessed spent fuel disposal into underground repository. The Czech research and development programme in the field of partitioning and transmutation is founded on the Molten-salt Transmutation Reactor system concept with fluoride salts based liquid fuel, the fue...

Characterization of Excavation Damaged Zone (EDZ) around an underground excavation is a major research topic for deep geological disposal of medium to high level radioactive waste. Rock fracturing due to excavation and thermal loading and its resultant rock mass permeability change in the EDZ are important aspects in the EDZ characterisation. A new function to predict rock mass permeability cha...

 Mineralogical Association of Canada Short Course 43, Winnipeg MB, May 2013, p. xx-xx INTRODUCTION The direct disposal of spent nuclear fuel in geologic repositories, built several hundred metres underground, has been under consideration internationally for 20 to 30 years. Various geologic formations are being, or have been, studied including tuff rock, salt domes, sedimentary clay deposits an...

In the last decade, voluntary efforts by firms to reduce their environmental impacts have received increasing attention from both policymakers and scholars. In this article, we consider polluters’ incentives to reduce their releases. In particular, using data from Canada’s National Pollutant Release Inventory, we examine the impacts of conventional regulation, threats of regulation, and non-gov...

The safety of an underground waste disposal site depends to a large extent on the presence and migration of the water in the rock. Geoelectrics is the most suitable method particularly in underground mining conditions to explore and monitor the moist zones in many different rocks. Recent developments in hardware, inversion schemes and petrophysical interpretation of the resistivity enable relia...

Significant interest has been devoted to claystones and shales in the context of geological radioactive waste disposal at great depth. The determination their mechanical properties is needed for appropriate design underground galleries tunnels. Given high sensitivity changes water content, special care be taken so as provide characteristics close possible (saturated) insitu ones. Based on hydro...

With the exception of recent progress in Sweden and Finland, traditional planned high-level nuclear waste processing disposal methods have yet to be successfully implemented on a commercial scale. Failure solve issue is an impediment expansion power production particularly North America Europe. Given these issues, this paper presents three speculative accelerator/reactor approach process waste....
