Abstract
With the sustained development in computer technology, the possibilities of code capabilities have been enlarged substantially. Consequently, 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 as coupled code technique. This method consists in coupling advanced codes 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. It has been found that suitable-mature methods exist, but the spread of these methods and procedures within the community of scientists working in research reactor technology is limited. The purpose of the present paper is to provide an overview of the accident analysis technology applied to the research reactor, with emphasis given to the capabilities of computational tools.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
