Proceedings | 16th International High-Level Radioactive Waste Management Conference (IHLRWM 2017) | Charlotte, NC, April 9-13, 2017 | Pages 344-346
For long-term assessment of the safety of final repositories for radioactive waste the program package RepoTREND is being developed and applied by GRS. The statistical framework of RepoTREND is called RepoSTAR. The development of this framework was motivated by a number of practical problems that occurred in the past when performing probabilistic analyses. In this paper we explain these problems and how they are handled by the new concept of RepoSTAR.
