Overview of accident analysis in nuclear research reactors

Advanced safety evaluations and design optimizations that were not possible few years ago can now be performed. Nowadays, it becomes possible to switch to new generation of computational tools in order to get better realistic simulations of complex phenomena and transients. The challenge today is to revisit safety features of the existing research reactors in order to verify that the safety requirements still met and when necessary to introduce some amendments, coming from not only the new requirements but also, in order to introduce new equipments from recent advancement of new technologies. The objective of this work is to give an overview of the state of the art in performing safety analysis of research reactors and to emphasize the need and the provision to achieve such goals.
