... SYNOPSIS: Around the world, there are many nuclear power generating stations producing nuclear waste and this necessitates a need for nuclear waste repositories. The repositories will consist of a large system of deposition tunnels caverns and deposition holes. As a consequence...

... particles can be neglected. Rutqvist et al. [5] have predicted coupled thermo-hydro- mechanical responses during an insitu heater experiment which simulates a nuclear waste deposition hole with a waste over-pack and bentonite buffer, surrounded by fractured rock. Chijimatsu et al. [6] conducted large-scale...

... with a distance of 30m between them. Because of the symmetry of the tunnel arrangement only a half of the whole structure is built in the model as shown in Fig. 1. The tunnels will be assumed to infinitely extend. Therefore, FLAC model consists of one unit section with a repository tunnel and a deposition hole...
