其他摘要：In this paper we present a brief description of the last version of the nuclear fuel performance code DIONISIO. Designed to describe most of the main phenomena occurring in a fuel rod during operation of the power reactor, the code is under continued development in the Code and Models Section of the Nuclear Fuel Cycle Management of CNEA. The new version of the code was improved with the incorporation of calculation tools designed to extend the application range of the code to high burnup and accident condition across the participation of two international projects sponsored by IAEA.
