Description

Special Publication 415

Understanding the behaviour of gases in the context of radioactive waste disposal is a fundamental requirement in developing a safety case for the disposal of radioactive waste. Of particular importance are the long-term performance of bentonite buffers and cement-based backfill materials that may be used to encapsulate and surround the waste in a repository, and the behaviour of plastic clays, indurated mudrocks and crystalline formations that may be the host rocks for a repository. The EC Euratom programme funded project, FORGE, has provided new insights into the processes and mechanisms governing gas generation and migration with the aim of reducing uncertainty. This volume brings together papers on aspects of this topic arising from both the FORGE project and work undertaken elsewhere. This has been achieved by the acquisition of new experimental data coupled with modelling, through a series of laboratory and field-scale experiments performed at a number of underground research laboratories throughout Europe.

This Special Publication summaries the recent research studies addressing these issues that were undertaken primarily within the EU Euratom programme FORGE (‘Fate Of Repository GasEs’) project.

The volume provides an excellent synthesis of the current research within this important area. All papers are well written and edited, concisely laid-out with clear and appropriate figures, photographs and data-tables. The inclusion of numerous colour figures and photographs enhances the understanding of the accompanying text.

The insights presented will be directly relevant to both research students and geoscientists in the field and practising radioactive waste management professionals undertaking potential repository design and performance evaluation, risk assessment and safety case development.
