Gas Generation and Migration Studies in Repositories
We provide an integrated package, based on laboratory, modelling and assessment studies, to address problems created by generation of gas in deep geological repositories and the implications for the short and long-term safety of the repository. We offer:
prediction of quantities and generation rates of gas arising from metals and organic materials, based upon waste inventory, repository design and the predicted ambient conditions (the GAMMON code);
calculation of gas migration through fractured or porous rocks containing liquids (the techSIM, CapFracBundle and PORES codes);
assessment of the consequences for repository performance of gas generation and migration;
assessment of consequences (radiological, toxicological, flammability) of release of gas to biosphere (GAS2/RIMERS);
design and execution of experimental programmes to provide key data, e.g., on gas production from corrosion or biodegradation;
development/tailoring of models
coordination of large multi-partner projects, for example the Europe-wide PROGRESS initiative sponsored by the CEC
internationally-recognised expertise on the effects of gas on repository safety NEA concerted action.
