Abstract: The enhancement of the breeder blankets operation efficiency is a challenging issue that assumes complex studies involving numerous neutronics analyses based on the Monte Carlo simulations. The current R&D work within EUROfusion DEMO project is concentrated on a search of the new water-cooled blanket layouts: a deep upgrade of the WCLL blanket to ensure a sufficient tritium breeding capability and an elaboration of the hybrid concept coupling technological advantages of water coolant, lead neutron multiplier and ceramic breeder. The presentation gives an outline of the developed simulation procedure to find an optimal breeder blanket design. Several geometry layouts of the hybrid breeder blanket were investigated to reach the TBR sufficient for a sustainable tritium fuel cycle. Promising novel solutions were suggested to significantly enhance the tritium breeding performance of this blanket. Various nuclear safety aspects of the technologies utilized in both blanket con-cepts are addressed in this work to facilitate engineering decisions aimed at the consolidat-ed blanket design for the upcoming DEMO reactor. The conclusion summarizes the pro-gress achieved and gives an outlook for future investigations.
