A PRACTICAL METHOD FOR COUPLED THM SIMULATIONS OF THE YUCCA MOUNTAIN AND FEBEX CASE EXAMPLES FOR TASK D OF THE DECOVALEX-THMC PROJECT
Task_D of the DECOVALEX_THMC project focus on predictive analysis of the long-term coupled processes(up to 10,000 years) in two generic repositories, FEBEX type and Yucca Mountain Project type for comparison. To better understand the coupled THM processes and their influence on the system behavior, we have introduced a set of generic coupled THM governing equations. Basing on these equations, we develop simplified models according to given Task_D model inception phase request. Boiling model and empirical bentonite swelling model are introduced into general simulation which makes model more practical. Our numerical code FRT-THM upon this practical models is developed and used in two BMT case study of Task_D. Simulation results are shown and verified in the 3rd and 4rh workshop of DECOVALEX_THMC in 2005. There is a good agreement with results of different participant teams which enhances confidence in prediction of coupled THM processes.
