Abstract
Several innovative solutions for a liquid metal fast reactor design are being investigated within the framework of the ELSY (the acronym for the European Lead-cooled System) Sixth Framework Programme of URATOM. Among these solutions the open-assembly core option adopted by ENEA for the preliminary neutronic analysis requires a new approach to the thermal-hydraulic core design. In addition, it could have important implication on the reactor safety. Therefore a two-step approach at the T/H analysis of the core is being followed: Utilization of a one-dimensional RELAP5 model for independent channels analysis for a prompt verification of the thermal-hydraulic and safety of the core neutronic design. Development of a dedicated tool for the evaluation of the intermingled effects between assembly flows.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
