A Coupled Modeling Simulator for Near-Field Processes in Cement Engineered Barrier Systems for Radioactive Waste Disposal

Evaluation on Mechanical Stabilities of Clay-Sand Mixtures Used as Engineered Barrier for Radioactive Waste Disposal

In this study, natural bentonite was used as natural clay material and samples were taken from the Kalecik district in Ankara. In this research, bentonite is the subject of an analysis from standpoint of assessing the basic properties of engineered barriers with respect to the buffer material. Bentonite and sand mixtures were prepared for tests. Some of clay minerals give relatively higher hydr...

Disposal of Radioactive Waste

Perhaps the most important single problem arising from the increasing use of atomic energy for peaceful purposes is how to dispose of the growing amounts of radioactive waste. Many of its complex aspects were discussed at the scientific conference on the disposal of radioactive waste held by IAEA in Monaco from 16 to 21 November 1959. The conference was organized jointly with UNESCO, with the c...

Cements in Radioactive Waste Disposal

The use of cement and concrete to immobilise radioactive waste is complicated by the wideranging nature of inorganic cementing agents available as well as the range of service environments in which cement is used and the different functions expected of cement. For example, Portland cement based concretes are widely used as structural materials for construction of vaults and tunnels. These const...

Investigations of Near-field Thermal-hydrologic- Mechanical-chemical Models for Radioactive Waste Disposal in Clay/shale Rock

Technical Considerations in the Design of near Surface Disposal Facilities for Radioactive Waste

FOREWORD The International Atomic Energy Agency (IAEA) has, since its inception, recognized the importance of radioactive waste management. Low and intermediate level radioactive wastes are produced in almost all countries and their safe management is of great importance. Near surface disposal of the wastes is an option being practised or planned in many countries. There is a growing need in th...
