The DECOY ALEX project is an international co-operative project, initiated by SKI, the Swedish Nuclear Power Inspectorate, to support the development of mathematical models of coupled THM processes in the host rock for potential nuclear fuel waste repositories. The DECOY ALEX project has been running for more than a decade the third phase of DECOY ALEX called DECOY ALEX III is now being finalized with two main objectives. The first objective is the validation of codes by simulating large-scale experiments. The second objective is to determine the relevance of THM processes on the safety of a repository. To achieve the second objective, benchmark tests are proposed, where typical repository designs, engineered barriers and host rocks are examined. The benchmark problem called BMTl defined in this paper looks at the implications of coupled THM processes on the near-field performance of a repository. The performance of a nuclear waste repository is dependent on two main components ...

In addition to deterministic analyses, and simulations performed with thermal-hydraulic computer codes, a level 1 PSA study has been performed for the BWR 90. It was adapted to the off-site electrical power grid in Finland and to recent data on common cause failures obtained from research work sponsored by the Swedish Nuclear Power Inspectorate (SKI). The PSA study addresses internal events only since previous studies have demonstrated that external events do not contribute significantly to the core damage probability. The PSA shows that LOCA events leading to core melt are extremely unlikely which is typical for BWRs with internal recirculation pumps.
