... Abstract The French National Radioactive Waste Management Agency (Andra) is in charge of studying the disposal of high-level and intermediate-level long-lived waste (HLW and ILW-LL) in a deep geological repository (Cigéo project) within the host formation is the Callovo-Oxfordian claystone...

... Abstract Nuclear waste disposal and spent nuclear fuel are a major concern in most countries. International Atomic Energy Agency (IAEA), the world's central intergovernmental forum for scientific and technical co-operation in the nuclear field, recommended the deep geological disposal for high...

.... 1 INTRODUCTION In the construction of an underground facility such as a repository for high-level radioactive waste (HLW) disposal, hydro-mechanical properties of the rock mass around a repository is expected to change significantly as a result of stress redistribution due to excavation...

... application examples are discussed in some detail: shale gas extraction, CO 2 storage, and radioactive waste disposal—with the emphasis being on successfully achieving the project objectives. The paper concludes with ten recommendations, concentrating on the further development of the subjects of uncertainty...

... of nuclear wastes which will be disposed around 400 m–1000m below ground inside the underground nuclear repository. The rock chosen is granite and barrier near the canister is proposed to be clay. In this paper, thermo hydro mechanical (THM) analysis has been done to study the effect of heat on deformations...

... ABSTRACT: Disposal of waste is an essential and important operation of surface mining. At present juncture, there are growing awarness of the problems of environmental pollutions due to waste disposal. Pollutions caused by waste disposal directly impacts on the health of human being, flora...

... ABSTRACT: Coal mine waste material which usually consists of coarse grained particles to rock fragments in gradation, pose unique geotechnical and environmental problems in their disposal. Study of geotechnical aspects is, thus very important in rational planning for disposal, reclamation...
