<p>The present paper focusses on different approaches of numerical model set up and discretisation based on the available geological models by using FEFLOW. In particular, the implementation of the complicated geology with regional faults and thrusts are presented ...

The disposal of nuclear wastes is one of the most controversial issues faced by authorities inJapan. In this regard, a survey was conducted among 172 university students to analyze the attitude towardsthe sitting of a nuclear waste repository in the country. ...

This report summarizes experience from geoscientific studies of the Excavation Damaged and Disturbed Zones in sedimentary rocks. The bulk of these studies have been performed as part of research programs for radioactive waste disposal in argillaceous rocks. ...

During the past decades comprehensive investigations have been made on bentonite clays in order to find optimal components of the multi-barrier system of repositories for radioactive waste. The present study gives a mineralogical characterisation of some selected ...

The technological implications of retrievability in geological disposal concepts are explored in this report. Scenarios for retrieving emplaced waste packages are considered and the report aims to identify and describe any related technological provisions ...

<p>Secure stability and reliable serviceability of radioactive dump is a difficult engineering problem. Due to difficult geological formations determined mainly by great compressibility, low shear strength of soils, and high ground water level, or great upward ...

Geological disposal of radioactive wastes is based on the principle that the deep rock environment is stable and largely unaffected by environmental change for hundreds of thousands – even millions of years – times that are longer than those since the appearance ...

Geological repositories for the disposal of high level radioactive waste are designed to provide isolation of the waste from the human environment for many thousands of years. Monitoring the environment of such repositories is not therefore expected to reveal ...

Most countries intend to dispose of their high-level radioactive wastes by converting them into a solidified wasteform which is to be buried within the earth. SYNROC is a titanate ceramic wasteform which has been designed for this purpose on the basis of geochemical ...
