Neutronic benchmark based on previous activities with ALLEGRO – gas cooled fast reactor demonstrator – was defined in the framework of EC project VINCO. This assembly based benchmark was solved by HELIOS and SERPENT codes and results were compared with other solutions. Main comparison results and conclusions are included in the paper as well.
