Project Details
Description
The deep geological disposal is considered for the long-term isolation of spent nuclear fuel (SFD)/ high-level radioactive waste (HLW) from biosphere. Coupled thermo-hydro-mechanical-chemical (THMC) processes occurs in deep geological repositories for SNF/HLW disposal. Therefore, the coupled THMC processes must be well understood for safe deep geological disposal because they play important roles in the design, construction, operation and close of a repository. Moreover, THMC processes should be predicted using the state-of-the-art numerical tools because they are integral to building confidence in the safety assessment. This project is thus designed to develop a novel numerical model for predicting the coupled THMC processes in a SNF/HLW disposal. In particular, the developed numerical model will fully couple THMC processes in a computercode rather than combining two different codes to sequentially simulate THMC processes. Several comparisons of the developed THMC numerical models against existing analytical models will be executed for verification andperformance evaluation of the newly developed model.
