Improvement, calibration and partial validation of the CODE_BRIGHT numerical code, considering coupled thermal, mechnical, and hydraulic processes in an engineered barrier composed of compacted benton

The most significant result is a validated model for predicting the THM processes in a clay buffer and its interaction with the host rock, to be used in the performance assessment exercises for HLW disposal in clayey formations.

The initial numerical model got additional developments/modifications for taking into account the specific characteristics of the host rock formation. The final adjustment of the model was done by adjusting rock and buffer parameters based on laboratory results, and by comparisons between the predictions made, and the test data recorded.
