The THERESA project (“Coupled thermal-hydrological-mechanical-chemical (THMC) processes for application in repository safety assessment“) was performed between January 1, 2007, and December 31, 2009, as a Specific Targeted Research and Training Project (STREP) within the Sixth Framework Programme of the European Community (contract no. FP6-036458).

 

The overall goal of THERESA was to develop a scientific method for evaluating the capabilities of mathematical models and computer codes used for the design, construction, operation, performance assessment (PA), safety assessment (SA), and post-closure monitoring of geological nuclear waste repositories. The project work consisted of five work packages (WP1-WP5). WP1 was the overall planning package, designed to supervise the implementation of the other four work packages throughout the duration of the project. In WP2, the issue evaluation tables (IETs) were developed with respect to WP3 and WP4.

 

Therefore, the specific issues in PA that are related to THMC modelling in rock salt, buffer, and buffer-rock interfaces were identified and with these results the project was guided in addressing the relevant issues in WP3 and WP4. WP3 and WP4 are the packages addressing numerical modelling of coupled processes, which are THM processes in salt (WP3) and THMC processes in buffer and buffer-rock interfaces (WP4). WP5 was defined to implement a technical auditing (TA) of the models and codes applied in WP3 and WP4, according to specificly developed IETs in WP2.
