RepoTREND is a new simulator designed to model the processes in a final repository for radioactive waste in different geological formations. RepoTREND provides functionalities for simulating the release of contaminants and their migration through the near-field and far-field to the biosphere, including the estimation of the radiological consequences for a human and the environment. In order to allow the statistical analysis of the models which are implemented in RepoTREND, a new concept named RepoSTAR was developed and realised as the statistical framework of RepoTREND. This paper provides a brief overview of RepoTREND.
