ELECTRA is the European lead cooled training reactor, which is a passively liquid lead cooled reactor of compact size fueled with plutonium nitride. This contribution aims at investigating the flow patterns in the reactor vessel and identifying modifications to the design. The investigation is carried out using 3D computational fluid dynamics. The core and the heat exchanger are modeled using the porous media approach in order to reduce the mesh size. The results show that a CFD approach can be used to model a full system such as ELECTRA. Changes to the thermal hydraulic design to ELECTRA are proposed, which include a redesign of the bottom plate to reduce the bypass flow and this way reduce the temperature difference over the core, which at the current design exceeds the design specifications.
